A Histopathological Study on Carious Permanent Teeth in the Population of Jalalabad

Background: Dental caries is an irreversible, multi-factorial disease that is ranked among the top most prevalent diseases. It involves the dissolution of inorganic components and the decomposition of the organic components of the tooth. It may extend from the enamel surface towards the inner structures in a horizontal, vertical, or oblique manner resulting in pain, sensitivity, and even extraction of the affected tooth. Objective: To determine the histological classification and extent of dental caries on ground sections of the permanently extracted teeth. Material and Methods: In this cross-sectional study, Participants were selected according to the inclusion criterion of the study; the sample teeth were collected, sterilized, decalcified, and ground with a slow hand-piece, lathe, and sandpaper to achieve 3-4mm thickness. Conventional H&E stain was used for tissue staining followed by light microscopy for reporting the observed cases. Results: Caries were more prevalent (84%) in the dentin-pulp complex. Males (77%) were more commonly affected as compared to females and the most common age group for caries development was 7-12 years. Mandibular molars were predominantly affected by dental caries, in permanent teeth, followed by maxillary molars. Conclusion: It can be concluded that the extent of dental caries is significantly associated with the path of decomposition of the inorganic and organic matrix of the tooth.
