Frequency of Class Ii Type Carious Lesions in First Permanent Molars and Their Association with Pulp

The objective of the present study was to determine the frequency of class II type carious lesions in first permanent molars and its possible association with the pulp when examined clinically and radiographically. Two hundred and forty two subjects were examined in the Dept. of Operative Dentistry, Khyber College of Dentistry, Peshawar for the presence of Class II type carious lesions in the period of two months. This study showed that 62 % subjects had a Class II type carious lesion. In the maxilla, unilateral class II carious lesions were 19% and bilateral 2.5%, while in the mandible, unilateral 36.4% and bilateral 4.1% respectively. The occurrence of class II carious lesions was more in females and in mandibular molars. Regarding pulp exposure, a significant relationship was present between clinical and radiographic examination.
