title: The retrocuspid papilla. A clinical survey.
abstract: 1. As mentioned previously in the literature, RCPs are commonly found in the young but become progressively less evident with advancing age. 2. The incidence of the RCP in Negroes is approximately the same as that in Caucasians. 3. Bilateral RCPs are more common than unilateral papillae. 4. The occurrence of RCPs is consistently more common in females than in males, in both Caucasians and Negroes. 5. Histologically, the RCPs are essentially normal, showing features indicative of those seen in frictional irritation during mastication and phonation. 6. The 72.5 per cent incidence of RCPs in children under 11 years of age confirms the trends of past studies and indicates that the RCP is a normal entity in pediatric dental patients and should be included in the literature as such. 7. The clinical significance of the RCP is that it be recognized as a normal anatomic structure that regresses with age and requires no treatment.
