Frequency of class II type carious lesions in first permanent molars and their association with pulp

ABSTRACT

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 call 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 lesion was more in females and in mandibular molars. Regarding pulp exposure, a significant relationship was present between clinical and radiographic examination
