Dental caries is a multi-factorial, dynamic and infectious microbiologic disease process resulting from imbalance in the physiologic equilibrium between the tooth mineral and the plaque liquid. The study design was cross-sectional. This study aim was to evaluate the frequency and distribution of dental caries in teeth and arches of caries patients reporting to department of Operative dentistry at Punjab Dental Hospital, Lahore.
