ClinConnect Summary

INTRODUCTION

The pulp tissue within the tooth and surrounding periodontium are interrelated to each other due to structural, functional and microbiological similarities. Cross infection of bacterial colonies take place in between these sites through dentinal tubules, apical foramen, lateral and accessory canals.Concurrent endodontic- periodontic lesions are those lesions where both endodontic and periodontal diseases occurring at same time in relation to single tooth.

Endodontic infection present in tooth is responsible for more bone loss, attachment loss and results in impaired healing o...
