Objective: To determine the morphological numbers of cusps and occlusal features of maxillary second molar among patients visited to Khyber College of Dentistry, Peshawar.
Materials & Methods: This was a cross-sectional study based on clinical observation among patients visited for oral health services other than for the treatment of maxillary second molar. A total of 200 patients were examined from July to December 2017. A thorough examination of the maxillary second molar was done using examination instruments. The data was entered into SPSS version 20 and analyzed for descriptive statistics. Chi-square test was used for comparing the occlusal features among gender where p ≤0.05 was considered as significant.
Results: Two hundred patients were included in the study, out of whom 112(56.0%) were male and 88(44.0%) female with a mean age of 23.0±5.0 (ranged from 15 to 37 years). Individuals with four cusps in the right maxillary second molar were 139(69.5%), while three cusps were 61(30.5%). The difference between gender was not significant (p>0.05). In right maxillary second molar distolingual cusp was observed in 59(29.5%) while in left maxillary molar distolingual cusp was found in 63(31.5%). There was no significant difference in gender. Oblique ridge and distal triangular fossa were present, while Cusp of Cerabelli was absent in all cases.
Conclusion: The maxillary second molar in the sample population is characterized by four and three cusps along with apparent oblique ridge and distal triangular fossa with no Cusp of Cerabelli. There are no significant difference among gender.
