Pate li životinje od karijesa, poput šupljina? Je li to u istoj mjeri kao i kod ljudi ili životinjski zubi manje ili više propadaju? Ako zubi propadnu i kod životinja, postoje li prirodne strategije koje životinje koriste za njihovo liječenje? I na kraju, kako se životinje brinu o svojim zubima?


Ako je to u usporedbi s ljudima, životinje su manje -više oslobođene od dviju uobičajenih zubnih bolesti zbog kojih se zubi gube kod ljudi. To su karijes (karijes) i parodontopatija (bolest desni).

Zajednički za obje bolesti je biofilm koji nastaje na zubima poznat kao zubni plak.

Ako je plak koloniziran acidogenim mikroorganizmima (koji stvaraju kiselinu), šupljine se stvaraju u prisutnosti rafiniranih ugljikohidrata.

Bolest desni nastaju bakterijskim toksinima iz plaka koji uzrokuju upalu okolne desni što rezultira gubitkom potpornih struktura zuba uključujući i kosti što rezultira olabavljenjem i gubitkom zuba.

Kod životinja u divljini nakupljanje plaka učinkovito se kontrolira grubom neprerađenom prehranom koja ima vrlo dobar učinak ribanja. Osim toga, divlje životinje nisu izložene rafiniranim ugljikohidratima poput šećera.

Stoga divlje životinje nemaju ove dvije bolesti. Međutim, pripitomljene životinje na ljudskoj prehrani sklone su sličnim bolestima.

U divljih životinja češće je ozbiljno trošenje (trošenje) i lom zuba.

Divlje životinje neće dugo preživjeti bez odgovarajućeg broja funkcionalnih zuba.


Ljudski karijes uglavnom nastaje konzumiranjem hrane bogate šećerom. Dakle, životinje općenito ne dobivaju karijes. (Osim za kućne ljubimce.) Ali životinje mogu imati i druge probleme sa zubima. Na primjer, slonovi melju kutnjake jedući toliko biljnog materijala. Na njihovu sreću, imaju zalihe novih kutnjaka koji redovito dolaze. Na njihovu žalost, ta je ponuda ograničena. Kad slonu ponestane kutnjaka, on umire od gladi. Drugi primjer je plak na zubima pasa, koji može dovesti do bolesti desni, baš kao i kod ljudi.


Izvan sisavaca životinje samo dopuštaju da ispadnu loši zubi i zamijene ih kao dio kontinuiranog ciklusa gubitka i zamjene zuba, oni ne drže zube dovoljno dugo da bi to mogao biti problem. Sisavci su ... čudni, dobivaju samo dva seta. Otišao bih dalje, ali Ramov odgovor pokriva kako se ovo pitanje prilično dobro odnosi na sisavce. Iako bih trebao napomenuti da ljudi imaju relativno tanku caklinu, dijeta je prilično niska u velikoj mjeri zbog izuma vatre.

II. ORCAS U ZAPOČENJU

Trenutno u zatočeništvu diljem svijeta živi oko 50 orki. Većina ovih kitova smještena je u morskim zabavnim parkovima u spremnicima ili oborima koji su samo dio veličine njihovog normalnog okoliša. Zatvoreni prostori i ograničena interakcija s drugim pripadnicima vrste ne uspijevaju ponoviti prirodno postojanje orke. To može dovesti do opasnosti po tjelesnu dobrobit životinje, kao i po stres za njezino mentalno zdravlje. Orke koje žive u zatočeništvu radi javnog prikazivanja žive znatno drugačije od svojih divljih kolega. Njihovo fizičko i društveno okruženje mijenja se njihovom prisutnošću u zatočeništvu.

A. Fizičko okruženje

Ne samo da je društvena struktura orke pogođena u zatočeništvu, već je i njezino stanište uvelike smanjeno, što ponekad uzrokuje fiziološke promjene. Zabilježeno je da su divlje orke ronile stotine stopa pod vodom, a rekordnih 1.000 stopa, a najveći dio vremena provode pod vodom. Zbog očiglednih strukturnih ograničenja, orke koje žive u zatočeništvu nemaju to mogućnost jer je prosječni izložbeni bazen dubok samo 27,6 stopa. [1] Dakle, skloni su provoditi većinu svog vremena na površini vode, osobito u interakciji sa svojim ljudskim trenerima i voditeljima. To potencijalno može biti uzrok onoga što je poznato kao "leđna opuštenost". Češće prisutna kod muškaraca (zbog njihove veće leđne peraje), "leđna opuštenost" je kada se leđna peraja sruši na sebe kao da je presavijena strana u luku. Neki nagađaju da dok kit provodi više vremena na površini, kit više ne koristi uzgon vode i peraja se ne može nastaviti održavati protiv gravitacije. Drugi kažu da je od hrskavice koja se srušila na sebe od stalnog plivanja u krugovima. Kitovi orke u zatočeništvu prisiljeni su plivati ​​u krugovima nasuprot 100 milja koje mogu plivati ​​u divljini. [2]

Neki se sisavci drže u ogradama umjesto u bazenima. Morske ograde ograđene su dijelovima otvorene morske vode ili lagune. Neki sugeriraju da su olovke bolje za kitove zbog prirodne morske vode i prirodnijeg okruženja. Međutim, još uvijek postoji više problema s olovkama. Obično su blizu zagađenja (otjecanje s ceste i kanalizacija iz septičkih jama na kopnu, fekalni otpad i detritus iz nepojedene ribe u raspadanju), te visoke razine zvučnog zagađenja prometom plovila i obalnim razvojem koje može uzrokovati nevolje i oštećenje sluha . [3]

Morske ograde obično se nalaze u područjima koja su izložena uraganima ili tajfunima. [4] Kitovi se obično ne evakuiraju što dovodi do bijega stranih vrsta u otvorene vode ili čak do smrti. [5] Kada je uragan Katrina pogodio 2005. godine, osam dupina je ostalo iza oceanarija Marine Life u Mississippiju. Svi su izvedeni u Zaljev u olujnom naletu. Na kraju su spašeni, što je koštalo desetke tisuća dolara novca poreznih obveznika. [6] Morske ograde također uzrokuju oštećenja prirodnih barijera u vodama jaružanjem i stvarnim fizičkim uklanjanjem istih kako bi se smjestili olovke.

Prirodne razine aktivnosti orke, društvenost, lovačko ponašanje, zvučna percepcija i tekstura njihovog prirodnog okruženja ugroženi su zatočeništvom. Stanište morskih sisavaca složeno je i teško te ga je često nemoguće ponovno stvoriti ili simulirati. Tipični bazeni kitova čine oko deset tisuća tisuća 1% njihove normalne veličine staništa. Stadion Shamu u SeaWorld San Diegu ima oko 2,5 milijuna litara vode. Da to stavimo u perspektivu:

Erich Hoyt u svom izvješću iz 1992. 'Orca koja izvodi' izračunao je da je (na temelju dnevnih putovanja mahune divlje orke i uzimajući u obzir čak i najmanju prijeđenu udaljenost, minimalnu dubinu zarona i tako dalje), minimalni volumen vode prešao prosječna 24 sata ukupno bi iznosila 6,006,000,000 kubnih stopa, što sadrži više od 45,302,778,000 galona. To je više od 9000 puta veće od zbroja međusobno povezanih bazena orka u Sea Worldu, San Diegu ili Orlandu. [7]

Mali bazeni stvaraju nedostatak aerobne kondicije i uzrokuju plivanje kitova u beskrajnim krugovima. Pokazalo se da veći bazeni smanjuju agresivnost i povećavaju uspjeh uzgoja. [8] Međutim, dužnosnici nastavljaju lobirati protiv bilo kakvih regulatornih revizija koje bi povećale standarde minimalne veličine bazena.

Dok neki bazeni koriste stvarnu slanu vodu ispumpanu iz oceana, većina to nije u stanju učiniti. Umjesto toga, moraju koristiti proizvedenu mješavinu morske vode primjenom metoda filtriranja i pročišćavanja kako bi osigurali bistrinu vode. "Orke imaju vrlo mali mjehur i mokre gotovo neprestano, proizvodeći nekoliko litara urina, kao i nekoliko kilograma polutekućeg izmeta dnevno", što je dosta posla na filterima. [9] Stoga se klor često koristi za nadopunu sustava za filtriranje jer je dobar dezinficijens i pomaže u održavanju bistrine vode. [10] Ova proizvedena voda još je jedna prilagodba koju kitovi orke moraju napraviti u zatočeništvu jer njihova tijela koriste prirodnu morsku vodu.

B. Društveno okruženje

Kada ih uzmu iz divljine, obiteljske veze su im narušene. Orke žive u skupinama matrilinealnih obitelji poznatih kao mahune sastavljene od 15-40 kitova. Orke u zatočeništvu ne doživljavaju društvenu atmosferu kakvu pokazuju njihove mahune u divljini jer, zbog ograničenja zadržavanja, tenkovi obično ne drže više od četiri orke. U zatočeništvu se različite populacije orka miješaju. I Atlantske i Pacifičke dionice smještene su zajedno. I rezidentne i prolazne orke smještene su zajedno iako se drže različite prehrane, imaju različite navike i društvenu strukturu [Za biološki sažetak orka, kliknite ovdje.] [11]

Kitovi ubojice komuniciraju i love pomoću eholokacije i zvukova sonara. Svaka mahuna ima svoj jezik komunikacije koji koristi istu vrstu zvukova. Čak i nakon godina provedenih u zatočeništvu, orke i dalje koriste jezik svoje obiteljske mahune, o čemu svjedoči orka po imenu Lolita koja je u zatočeništvu gotovo četiri desetljeća. Život unutar bazena okruženog bijelim cementnim zidovima nudi malo za stimuliranje orke, a njihovi zvukovi često se iskrivljuju kada se odbiju od zidova zbunjujući kitove i otežavajući međusobnu komunikaciju.

C. Zdravlje

Orke u zatočeništvu suočavaju se s jedinstvenim nizom zdravstvenih problema od svojih divljih kolega. Čini se da stanje zatočeništva povećava učestalost nekih infekcija koje se rijetko sreću u divljim populacijama. "Izvještaji o obdukciji (obdukciji) obično prijavljuju najezdu parazita poput nematoda, trematoda i trakavice." [12] Povećana razina stresa može dovesti i do tjelesnih zdravstvenih problema. Neke se orke brzo prilagođavaju životu u zatočeništvu, dok se druge ne. Mnogi čimbenici mogu dovesti do veće razine stresa, uključujući kretanje kitova, ljudsku interakciju, konkurentsku društvenu strukturu kitova i performanse. Stres tada može dovesti do oštećenja imunološkog sustava ostavljajući kitove osjetljivijima na infekcije. Izvješća su pokazala "visoku učestalost smrti uslijed bakterijskih infekcija, osobito infekcija gornjih dišnih putova. Iako takve infekcije nisu samo zarobljenici, može se zaključiti da su pogoršane, ako ne i uzrokovane, izrazito umjetnim uvjetima zatočeništva." [13] Orke u zatočeništvu obično umiru od bolesti koje nisu povezane sa starošću, možda zbog smanjenja dugovječnosti u zatočeništvu.

Agresija, i među kitovima i prema trenerima, zabrinjava i istraživanja. Budući da su kitovi različitih populacija i mahuna zajedno smješteni, postoji stalna borba za dominaciju u društvenoj strukturi. Kitovi će nabiti druge kitove kako bi pokazali dominaciju ili nekompatibilnost među kitovima. Također je poznato da iskazuju agresiju prema sebi, u onome što znanstvenici vjeruju da je ponašanje izazvano stresom. Zapaženo je da kitovi udaraju glavom o bočne strane spremnika i da im nanose štetu, pa čak i prijelome lubanje. Čini se da je agresija prema njihovim trenerima najveći problem jer uključuje sigurnost ljudi. Godinama su zabilježeni slučajevi kitova koji su vukli trenere na dno bazena, hvatali ih za noge i iskakali iz vode kako bi se spustili na svoje trenere. Neki su incidenti doveli do toga da parkovi nisu dopuštali ljudsku interakciju u bazenima s orkama, ali nakon nekog vremena parkovi su dopustili trenerima povratak u bazene. "Čini se najvjerojatnije da agresija proizlazi iz kombinacije čimbenika: stres neprirodnog zatvaranja, ponekad s nekompatibilnim partnerima u bazenu, pritisci od mladih i često neiskusnih trenera u vrlo umjetnom i bučnom okruženju i iznad svega, čista frustracija i dosada svojstveni situaciji u zatočeništvu. " [14]

Još jedno zdravstveno pitanje zarobljenih orki s kojima se rijetko može znati su stomatološki problemi. Loše zdravlje zubi može dovesti do prerane smrti među kitovima. Primarni čimbenici za razvoj zdravstvenih problema zuba u kitova su starost i zatočeništvo. Slomljeni i slomljeni zubi nisu neuobičajeno mjesto u morskim parkovima. Većina štete nastaje zbog prikaza prijetnji između kitova poznatih kao "puckanje čeljusti". Pucanje čeljusti je kada kitovi, obično odvojeni čeličnim vratima, udaraju o vrata u nastojanju da pokažu dominaciju. [15] Prijelomi zuba mogu dovesti do kronične boli koja može rezultirati kitovima koji se samelju u čeljusti.

Drugi uzrok zdravlja zubi su postupci poznati kao "spljoštavanje" zuba i "bušenje zuba". "Malo je ljudi svjesno prakse u kojoj se zatočenim orkama rutinski izbušu rupe u zubima, kao i" brušenju "ili" spljoštenju "zuba." [16] Kitovi tada obično dobivaju "ispiranje zuba" tri puta dnevno, gdje se zubi "ispiru" "punjenjem spremnika uređaja otopinom betadina koja se ispumpava u čeljust." Rupe na zubima treba isprati jer ako se ostaci hrane ne isperu, to može dovesti do infekcije. Loša njega zuba može dovesti do drugih zdravstvenih problema kao što su endokartisa, upala pluća, sepsa, srčana bolest. [17]


Pseći zubi: savjeti za njegu

"Pranje zuba vašem psu prva je obrana od bolesti desni", kaže dr. Lippman. "Svakodnevno čišćenje, zajedno s povremenim profesionalnim čišćenjem kod vašeg veterinara, učinit će mnogo za sprečavanje bolesti desni."

Što mogu koristiti za pasju zubnu pastu?

Za pranje pasjih zubi kod kuće, roditelji kućnih ljubimaca mogu isprobati enzentni komplet enzentnih četkica za zube Vetoquinol Vet Solutions za odrasle pse ili Nylabone naprednu stomatološku garnituru za njegu štenaca. Ovi kompleti za zube za pse dolaze s četkicom za pse i pastom za pse posebno dizajniranom za njegu pasjih zubi.

Kako biste spriječili nastanak plaka, maramice za pse koje se lako koriste, poput zubnih maramica za pseće naslage od svježe nane Petkin, može pomoći u uklanjanju dnevnih ostataka. Također možete osvježiti dah vašeg psa dodatkom u vodi, poput dodatka vode za svježe dah TropiClean, koji je formuliran da spriječi nakupljanje kamenca i promiče opće oralno zdravlje.

A, ako želite održavati zube vašeg ljubimca zdravim između četkanja i veterinarskog čišćenja zubi, pokušajte koristiti zubne žvakaće pseće zube ili poslastice, poput zubnih pasa Greenies ili stomatoloških pasa dr. Lyon. Ove zubne poslastice za pse pomažu u borbi protiv nakupljanja naslaga i zubnog kamenca, kao i osvježavaju dah vašeg psa.

Još jedna izvrsna opcija je VetriScience Perio Support puder, koji je prirodno enzimsko sredstvo za čišćenje pasa i jednostavno se svakodnevno dodaje u njihovu hranu.

Yosry S Morsi

Tehnološko sveučilište Swinburne

Biografija

Profesor Morsi magistrirao je, doktorirao. i D.I.C. s Imperial College/University College London te je svoju početnu akademsku izobrazbu proveo kao znanstveni novak na UCL -u i kao predavač na Loughborough University of Technology UK. Istraživanje dr. Morsija usmjereno je na eksperimentalnu i numeričku kvantifikaciju jednofaznih i višefaznih tokova u složenim okruženjima. On je priznati stručnjak za primjenu tehnika laserske dijagnostike, kao što su LDA, PIV i analizator dinamike čestica, kao i računske dinamike fluida za analizu problema protoka tekućine i hemodinamike u industrijskim istraživanjima. Tijekom svoje karijere, koja se proteže kroz 30 godina, profesor Morsi obnašao je dužnosti u industriji i niz viših akademskih pozicija, uključujući predavanje istraživačkog nadzora nad istraživačkim vodstvom i industrijsku suradnju. Također je bio član brojnih viših akademskih odbora i odgovoran za upravljanje vlastitom istraživačkom grupom, kao i za doprinos u upravljanju svojim fakultetom. Doktor Morsi trenutno je profesor biomehaničkog inženjerstva na Fakultetu inženjerskih i industrijskih znanosti (FEIS) na Tehnološkom sveučilištu Swinburne u Melbourneu u Australiji. Godine 2003., kao odgovor na stratešku inicijativu prorektora Swinburnea, profesor Morsi osnovao je Laboratorije za tkivno inženjerstvo i biomehaniku u Institutu za industrijsko istraživanje Swinburne (IRIS). Ti su se laboratoriji sastojali od odjeljka za mehaniku bio-tekućina za modeliranje i proizvodnju posebno dizajniranih skela za stanično dinamičko i in vitro kondicioniranje, kao i laboratorija za kulturu tkiva, opremljenog za staničnu kulturu, karakterizaciju, histomorfometrijsku analizu stanica i konstruiranu stanicu/polimer konstrukti. Grupa za biomehaniku i inženjering tkiva koja radi u tim laboratorijima interdisciplinarni je tim s različitim iskustvom u hemodinamici, CAD modeliranju, dizajnu skela i kulturi stanica. U projektiranju i optimizaciji skela koriste se različite proizvodne tehnike, poput modeliranja taloženim taloženjem i elektropredenja, za izradu biokompatibilnih i biorazgradivih materijala. Laboratoriji su također aktivni u biomehanici inženjerskih tkiva, s posebnim naglaskom na razumijevanju procesa in-vitro i in-vivo remodeliranja iz funkcionalne bio-mehaničke perspektive. Štoviše, CFD i interakcije tekućina-struktura (FIS) stalno se koriste za usavršavanje dizajna skela za različite primjene mekih i tvrdih tkiva, uključujući srčane zaliske i različite konfiguracije arterija. Istraživanje koje je provela grupa profesora Morsija u konačnici ima za cilj stvaranje živih srčanih zalistaka i arterija kao zamjenskih entiteta, umjesto korištenja trenutne mogućnosti umjetnih srčanih zalistaka i stentova. Dosad je stvorena poliuretanska skela sa srčanim ventilom s tri krila, a dizajn se stalno poboljšava pomoću in vitro bioreaktora za simulaciju prirodnih srčanih zalistaka. Grupa je uspješno proizvela prvu australijsku skelu s ovčjim srčanim zaliskom (s CT-om) izrađenu od poliuretana. Ovaj rad je uključivao izradu celulariziranih predložaka za skele za definirano kondicioniranje protoka u bioreaktorima. Ljudske mezenhimalne matične stanice također su korištene za stvaranje sva tri sloja listića srčanih zalistaka.

Perform the Experiment

  1. Boil the eggs, making sure to have a few extra in case some of them crack while you boil them. A cracked shell will change the results of the experiment.
  2. Help your child fill each of the plastic cups, one with regular soda, one with diet soda, and one with water.
  3. Once the eggs have cooled, have your child put one in each cup and leave it overnight.
  4. Ask your child to check the eggs the next day. You may need to pour the liquid out of the cup to see how each egg has been affected. Most likely, the eggs in the cola have been stained by the liquid overnight.
  5. Discuss the changes you see in each egg and ask your child what they think happened. Then ask what they think you can do to “help” the eggs that have been immersed in soda get back to their original state (no stains).
  6. Give your child a toothbrush and some toothpaste to see if he can brush the stains off the eggshell.

As a variation, you might also want to boil a few extra eggs and add cups with clear soda, orange juice, and coffee for comparison.


Dental enamel can't regenerate, right? Razmisli ponovno

Zasluge: CC0 Public Domain

Dental enamel is tricky stuff. Even though it's the body's hardest material, if it wears away from cavities, acidic food or drinks or overbrushing, it doesn't regenerate.

All that could change in the future, though. Ostrow Professor Janet Moradian-Oldak has been developing a special hydrogel that can promote the growth of an enamel-like surface on teeth and remineralize the dentin.

The patented hydrogel is based on chitosan-amelogenin peptide. Amelogenin is a substance that animals and human use to build dental enamel. A peptide is a chain of amino acids.

Painting on protection

Moradian-Oldak has received three new grants to continue her work. One grant will allow her to test the use of amelogenin-derived peptides in the gel. She explains that using short peptides—like the one she's using derived from the main protein in enamel—has a few benefits over longer ones: It's less expensive, and the path to getting this approved by the U.S. Food and Drug Administration is simpler. Peptides could be incorporated into a gel that could then be painted onto teeth eroded by early cavities or hypersensitivity.

She has already found that the peptide can regrow the aprismatic-like layer on teeth. Now the researchers will test whether this hydrogel works also for dentin remineralization.

The second grant will continue the work to understand the basic structural biology of tooth enamel, and the third grant is the exploratory proposal, with the idea to completely use chemistry strategies to synthesize a material similar to enamel in its properties. "Our idea is to use these short peptides to eventually develop new filling material," explains Moradian, who works out of USC's Center for Craniofacial Molecular Biology.

Creating artificial cavities

To test the new hydrogels, Moradian-Oldak has developed a method. She and her team of students—including Qichao Ruan, Kaushik Mukherjee, Gayathri Viskan and Amrita Chakraborty DDS '19—use a diamond saw to slice third molars (wisdom teeth) into uniform thin discs. They then paint the teeth with a clear nail polish, leaving only a small window of unpainted surface. The researchers then place the tooth slices in acid to demineralize the exposed parts, creating artificial cavities or lesions.

Net, they put the hydrogel on those lesions and place the teeth in artificial saliva—made from calcium phosphate—to see how the gel promotes new growth on the enamel's surface. To test the hardness, Oldak teams up with a mechanical engineer with special machines. She also uses microscopes to analyze the regrowth's composition.

Overall, she's testing her models against teeth treated with fluoride. "Our goal is to achieve properties that are comparable with natural tooth or other treatment modalities," she says. Fluoride is a cheap and easy way to make teeth stronger: it basically crates patches of calcium-phosphate deposits on top of the tooth, blocks the dentinal tubules.

"Fluoride promotes mineralization, and it really helps, but it doesn't rebuild enamel the way our peptide does," Oldak says. "Fluoride is really about blocking the nerve, and our peptides are made in a biomimetic [lifelike] way."

Oldak started off as a chemist with a background in biomineraliziation, studying the mechanisms that organisms use to make minerals in their bodies like teeth, bone, seashells or even kidney stones. "I wanted to expand the basic science into something translational, something that could be developed as a treatment," she says. Teeth were a perfect fit.

Future patients would not be able to avoid going to the dentist altogether, she says. "We don't have an intention to jeopardize dentistry jobs," she says. "You would still need to go to the dentist. But the most important implication is really preventing deep decay by addressing lesions early, to rebuild the lost enamel."


How Poor Oral Hygiene Affects Your Dog

If left unaddressed, dental disease can cause progressive issues that put your dog’s entire body and overall health at risk.

Here are some of the health problems that can result from periodontal disease.

Gum Inflammation

Beneath the gumline, the bacteria associated with plaque release toxins that damage the surrounding tissues.

White blood cells then enter those areas in an effort to destroy the bacteria. This process causes significant inflammation of the gums, known as gingivitis.

The inflammation causes the gums to look abnormally red and puffy, and the tissue may bleed when touched.

Inflammation also commonly leads to periodontitis, or loss of the supportive, structural tissues surrounding the teeth.

When white blood cells attempt to clear accumulating bacteria, the resulting inflammatory process erodes the supporting tissues of the tooth. Over time, this destruction causes structural weakening of the tooth sockets and jaw bones.

Symptoms of periodontitis include loose teeth and infection or fracture of the jaw.

Kidney and Liver Disease

Oral inflammation allows bacteria in the mouth to enter directly into the bloodstream. Once circulating, these bacteria can travel to and establish in other organs, especially the liver and kidneys.

Organ infection (like liver disease or kidney disease) and failure are well-documented consequences of untreated canine periodontal disease.

Chronic inflammation from periodontal disease can also increase a dog’s risk of heart disease.

Circulating bacteria can cause an inflammatory condition known as endocarditis. Studies have also shown that dogs with dental disease have an increased risk of congestive heart failure, a progressive and potentially fatal disease.

Loss of Weight and Appetite

Dental issues may cause feeding to become an uncomfortable or even painful process for your dog. As a result, they may be reluctant to open their jaw and chew food properly, and may drop food from their mouth while eating.

Over time, the reluctance to eat can take a toll on your dog’s body condition, leading to weight loss.

Poor appetite and weight loss may also indicate that dental disease is causing chronic problems in the liver, heart and kidneys.

Diseases of the teeth and gums are common in cats. Studies report that between 50 and 90% of cats older than four years of age suffer from some form of dental disease, but fortunately the most common forms of these diseases are largely preventable or treatable with appropriate preventive dental care and monitoring.

The three most common dental diseases in cats are gingivitis, periodontitis, and tooth resorption, and the severity of each of these conditions can vary significantly. Dental disease in cats can cause serious pain and discomfort, which can impact a cat’s quality of life. In many cases, dental disease causes a cat to stop eating, which leads to a variety of health problems.

Gingivitis
Gingivitis is a condition in which the gums around the teeth become inflamed (red, swollen, and painful). This inflammation is usually the result of a process that begins with the buildup of plaque, a film that harbors bacteria, on the teeth. In cats with good oral health, the bacteria that live in this film are believed to be beneficial, and the plaque that harbors them accumulates above the line where the base of the teeth meets the gums (gingiva).

If not regularly removed, plaque migrates deeper toward where the gingiva meets the base of the tooth. Eventually, plaque will migrate below this point to the subgingival region, where a cat’s immune system may mount a response to these bacteria, resulting in the inflammation that we refer to as gingivitis. Some researchers believe that the onset of gingivitis may be caused by a shift in the populations of bacteria in plaque from normal, healthy species, to disease-causing species. Tooth crowding and insufficient oral health care may contribute to plaque accumulation.

When plaque becomes hardened by absorbing minerals from both the saliva and from the gingiva itself, it is referred to as calculus or tartar. Calculus provides a rough surface that disease-causing species of bacteria can attach to. It is not the calculus itself that promotes an inflammatory response, but rather the bacteria that attach to the calculus.

Disease-causing bacteria that accumulate on and below the gums produce substances that damage the cells that form a barrier between the gums and the teeth. This allows the bacteria access to the connective tissue below the teeth where the cat’s immune system will probably react by making the gums inflamed and painful. If the cat’s immune response to these disease-causing bacteria is strong, he or she will develop gingivitis, but it is also possible the cat’s immune system will tolerate the bacteria without any detrimental effects on either.

Gingivitis may also be brought on by a number of infectious or systemic diseases, including feline leukemia virus, feline immunodeficiency virus, feline calicivirus, severe kidney disease, diabetes mellitus, and autoimmune disease. When caused by one of these systemic diseases, gingivitis may be accompanied by inflammation or sores in other parts of the pink mucous lining of the mouth, a condition known as stomatitis.

Gingivitis is characterized by swelling, redness, discomfort, and, in severe cases, bleeding where the gums and the teeth meet (the gingival margin). Depending upon the severity of the gingivitis, cats may be hesitant to eat, may turn their heads unusually while eating, may stop eating, drool, or develop bad breath (halitosis). In some cases, cats with gingivitis will show a preference for soft foods.

The best way to prevent gingivitis in cats is to regularly remove plaque build-up by tooth brushing (see Figure 1). It is important to use only tooth gel or toothpaste designed specifically for cats, as human products can be toxic to cats. While some cats require gradual introduction before they will allow regular tooth brushing, most cats can eventually be trained to accept this preventive measure. If a cat has severe gingivitis, tooth brushing can be quite painful, so consult with a veterinarian before considering brushing the teeth of a cat with gingivitis.

Luckily for cats who have already developed gingivitis, the condition is usually reversible. The recommended treatment will depend upon how severe your cat’s case is and on the underlying cause, and may involve cleaning your cat’s teeth at home, giving him or her antibiotics (either taken as a pill or as an oral rinse), scaling of inflammation-inducing plaque from the teeth (which usually requires anesthesia), the use of immunosuppressive drugs, and in extreme cases, the removing of teeth that may serve as sources of inflammation. There is little or no evidence that treating gingivitis with antibiotics alone is effective.

In cases of feline gingivitis that are due to systemic or infectious underlying diseases, it is important to address the primary disease in order to manage the gingivitis.

Periodontitis
If gingivitis is not controlled, it can progress to periodontitis, a condition that eventually cannot be reversed. In periodontitis, the tissues that attach the tooth to the underlying gums and bone are weakened as a result of damaging substances produced by disease-causing bacteria and the inflammation caused by the cat’s own immune system.

The destruction of the tissues that attach the tooth to both the soft and bony structures that anchor the tooth may lead to loose teeth and tooth loss. Periodontitis is almost always the result of untreated gingivitis, so controlling this inciting process is crucial.

Given that gingivitis leads to periodontitis, most cats with periodontitis will show signs of gingivitis (redness, swelling, bleeding along the gingiva at the base of the teeth), and may also be reluctant or unwilling to eat, drool, turn their heads to the side when chewing, and develop halitosis. In addition to these signs, they may show recession of the gingiva, exposure of tooth root surfaces, and mobility of the teeth. In extreme cases, a cat may lose one or more teeth.

A complete evaluation of cats with periodontitis involves probing the gums, and examining X-rays of the head and jaw, which require anesthesia.

To treat feline periodontitis, your veterinarian will recommend removing plaque and mineral buildup by scaling and polishing the teeth while trying to save the teeth wherever possible. In extreme cases of periodontitis, extraction of teeth, sometimes of numerous teeth, may be required.

Tooth Resorption
Tooth resorption is a process in which the tooth structure breaks down, beginning inside the tooth, and often progressing to other parts of the tooth. Tooth resorption is the most common cause of tooth loss in cats, and between 30 and 70% of cats show some sign of this destructive process. The cause of tooth resorption is not known.

Tooth resorption in cats is usually first identified as a pinkish defect in the tooth at the line where the tooth meets the gums. By the time a defect like this shows up, the tooth is already significantly damaged. Resorptive lesions like these can vary in severity from relatively small defects at the gum line to large defects in the enamel of the tooth crown. Tooth resorption may or may not be associated with gingivitis.

Tooth resorption can be very painful, so affected cats may be reluctant or unwilling to eat, may drool, turn their heads to the side while eating, and may be irritable. Veterinarians will usually make a diagnosis by examining the mouth and teeth, carefully probing any lesions, and examining X-rays of the head and jaw, which require anesthesia.

To treat feline tooth resorption, a veterinarian will aim to manage the cat’s pain, prevent the condition from progressing, and restore the function of the tooth or teeth as much as possible. Your veterinarian may recommend careful monitoring in cases in which lesions are limited to the tooth root and obvious discomfort is not apparent.

In cases in which a cat is showing signs of pain or discomfort and the lesions extend into the crown of the tooth, it’s best to remove the tooth. If there is significant damage, it can be difficult to extract the entire tooth. In these cases, your veterinarian may consider amputating the crown of the tooth (the part visible above the gum line). Regardless of the treatment, careful follow-up and monitoring are important.
