Comparison of feline odontoclastic resorptive lesions with caries in humans - similarities and differences

U ovom radu dana je usporedba odontoklastične resorptivne lezije u mačaka (FORL) s humanim karijesom, kao dvije najčešće dijagnosticirane bolesti u usnoj šupljini ovih dviju vrsta. FORL najčešća je bolest zuba u felida što prouzroči bol, gingivalnu upalu, uništavanje parodontnog veziva i gubitka zuba. Progresivna je bolest te je jedini tretman ekstrakcija zuba. Klinički se očituje hiperplastičnom ili hiperemičnom gingivom, a lezije su najčešće locirane na području premolara vrata zuba te se nazivaju vratnim lezijama. Specifične promjene koje se javljaju kod FORL-a su hipercementoza koja prouzroči gomoljast oblik vrha korijena, supererupcija, zadebljanja kosti duž alveolarne granice ili površine alveolarnih ploča. Simptomi su hipersalivacija i bolnost u području čeljusti gdje su oboljeli zubi i bolnost zuba zbog otvorenog pulpinog kanala. Karijes je po učestalosti druga bolest čovječanstva te obično započinje na mjestima gdje se najviše nakupljaju ostatci hrane te se oblikuje zubni plak, a to su fisure zuba, plohe između zuba i vratni dijelovi zubne krune. Simptomi mogu uključivati poteškoće s prehranom i bol, a komplikacije koje se mogu javiti su upala gingive, infekcija ili apsces te gubitak zuba. Inicijalna karijesna lezija obično započinje kao proces demineralizacije na glatkim plohama, a prikazuje se kao bijelo zamućenje, odnosno bijela mrlja. Specifične promjene koje se javljaju kod karijesa su tubulusna skleroza, odgovor pulpe na različite stadije razvoja karijesa u obliku tercijarnog dentina te recesija gingive. Karijes se liječi konzervativno ili operativno. Iz svega navedenoga se može zaključiti da se FORL i karijes razliku po simptomima, etiologiji i terapiji, a najbitnija je razlika histopatološka.In this review article, feline odontoclastic resorptive lesion (FORL) was compared with human caries as the most commonly diagnosed disease in the oral cavity of both species. FORL is the most common disease of teeth in felines and causes pain, gingival inflammation, destruction of periodontal tissue and tooth loss. FORL is a progressive disease and the only treatment is tooth extraction. It is clinically manifested by hyperplastic or hyperemic gingivitis, and the lesions are usually located in the area of the neck of the tooth and are called cervical lesions. Specific changes that occur in feline odontoclastic resorptive lesion are hypercementosis, which causes bulb on the roots and super-eruption and thickening of the bone along the alveolar surface. Caries is the second most common human ailment and usually appears in places where food remains trapped and dental plaque is formed, i.e. in the tooth fissures, surfaces between teeth and the cervical parts of the tooth crown. Symptoms may include eating disorders and pain, while possible complications include inflammation of the gingiva, infection or abscess and loss of teeth. The initial carious lesion usually begins as a process of demineralization on smooth surfaces and appears as a white blur or white stain. Specific changes in caries are tubular sclerosis, pulp response at different stages of caries development in the form of tertiary dentine and gingival recession. Medical treatment of caries can be conservative or surgical. In conclusion, FORL and caries differ in their symptoms, etiology and therapy, while the most important difference is in their histopathology
