Different Cuspal Pattern In Mandibular Second Premolar And Its Association With Other Dental Anomalies

Original Article

Abstract

Objective: to ascertain the unique cuspal pattern in the mandibular second premolar and how it relates to further
dental abnormalities.
Study Design: This was a descriptive cross-sectional study.
Place and Duration Of Study: This study was conducted in the Orthodontic Department of Sardar Begum
Dental College Peshawar from June 2014 to July 2015.
Methodology: 370 individuals, 165 men. Non-probability selection procedures were used to choose 205 female
participants for the research who met the inclusion and exclusion criteria. Casts from the orthodontics department of
Sardar Begum Dental College in Peshawar were used for the research. Each cast was categorized as either tricuspidate
or bicuspidate. Data analysis was performed using SPSS version 16. Chi-square and the odds ratio were used to
compare the groups. A p-value of less than 0.05 was deemed significant.
Result: It is not statistically significant that the tricuspidate pattern, mostly seen in females (56%), is more frequent
in men (66%). The relationship between dental abnormalities and tricuspidate and bicuspidate was not statistically
significantly different. The maxillary canine impaction, peg lateral maxillary incisor, absent maxillary lateral incisors,
and Carabelli cusps all have P-values over the crucial threshold.
Conclusion: The bicuspidate pattern is typical of second premolars in the mandible. Two cuspal variations in the
mandibular second premolar do not significantly correlate with other dental abnormalities.
