Abstract

This observational study aimed to determine the prevalence and identify the presence of mamelons while simultaneously correlating the age, gender, and bite relationship of the subjects.

Total sample size included 518 patients, both males and females. Study participants were selected by systematic random sampling using the randomizer.org website. Clinical examination as well as the presence of mamelons on each jaw and the relationship of anterior teeth such as open bite, functional contact, or not were screened by trained personnel performed by using a mouth mirror, latex gloves, a dental probe, and a dental chair light.

256 (49.4%) males and 262 (50.5%) females participated in this study. It was observed that the presence of mamelons was more frequent among females (84.7%) rather than males (79.3%). During the first decade of life, the percentage of mamelons is higher, irrespective of gender. However, the frequency and percentage of mamelons start to decrease with age. Mamelons are more prevalent in an open bite occlusion (90.0%) followed by a non-functional occlusion, i.e., 81.7% (edge to edge relation) and then a functional occlusion, i.e., 75.5%.

Persistence of mamelons in either gender is higher up to the age of 25 years, afterward mamelons dramatically reduce. Additionally, mamelons appear more in maxillary incisors than mandible incisors.
