Frequency and distribution of dental caries in teeth and arches of patients examined at Punjab Dental Hospital, Lahore

Worldwide prevalence of dental caries is very high reaching to more than 95% in developing countries. . 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. Total of 15323 patients with caries reporting to the OPD of Operative dentistry at Punjab Dental hospital were examined with age range of 10 to 60 years or more. Frequency of carious teeth in age group 20-29 years was maximum and minimum in age group 60 years or more. Dental caries was more prevalent in mandible [53%][n=8162] than in maxilla[47%] [n=7158]. In both the arches, first molars were the most frequently affected teeth by caries. Caries was found to be more prevalent in mandible than maxilla

Dens invaginatus: aetiology, classification, prevalence, diagnosis and treatment considerations

Dens invaginatus is a developmental malformation of teeth.Affected teeth show a deep infolding of enamel and dentine starting from the foramen caecum or even the tip of the cusps and which may extend deep into the root. Teeth most affected are maxillary lateral incisors. The malformation shows a broad spectrum of morphologic variations and frequently results in early pulp necrosis. Root canal therapy may present severe problems because of complex anatomy of teeth. Aetiology, classification, prevalence, diagnosis and treatment considerations are reviewed

Management of crown-root fracture - a case report

This case report describes the management of an oblique crown-root fracture of maxillary left lateral incisor. After removal of the fractured fragment, endodontic treatment, the remaining tooth was provisionally restored. The tooth was then orthodontically extruded by 3 mm to raise the defect supraginigivally. Periondontal fibres were cut with a surgical blade. A metallic screw type post was inserted in the root and core was built with composite restoration. Porcelain fused to metal crown was fitted over the core built up. This case report demonstrates that a multidisciplinary treatment approach to an oblique subgingival crown-root fracture is a reliable and predictable option to save a tooth
