Prevalence of cusp of carabelli in permanent teeth in a group from Khyber Pakhtunkhwa, Pakistan

ABSTRACT

The aim of this study was to determine the prevalence of cusp of carabelli in permanent teeth in a sample from the population of Khyber Pakhtunkhwa. A special proforma was developed to collect the data. A total of 400 subjects [patients attending Khyber College of Dentistry hospital and students of Khyber College of Dentistry] were included in the study. Cusp of Carabelli was present in 29.7% of the study population in maxillary first permanent molar and was totally absent in maxillary second permanent molars. Prevalence in males [31.9%] was slightly greater than females [25.9%]. Similarly unilateralism was also greater in males than females. It was concluded that the prevalence of cusp of Carabelli is lowest in the population sample of Khyber Pakhtunkhwa as compared to other similar Asian population's samples. However, unilateralism was at par with other Asian studies. In permanent teeth the Cusp of Carabelli occurs only on maxillary first molar
