Official Title: Evaluation of Endodontic Status on Periodontal Healing of Concomitant Endodontic Periodontal Lesions

Brief Summary:

Introduction:

To evaluate the effect of untreated endodontic infection on periodontal status in untreated non vital teeth with periapical radiolucency as compared to contralateral vital teeth. And also to evaluate the role of endodontic treatment on periodontal healing in successfully endodontically treated teeth with contralateral vital teeth.

Methods:

This study was performed in two parts. First part of this study was an observational cross sectional survey and second part was a clinical trial on patients selected from the survey.

Title: EVALUATION OF ENDODONTIC STATUS ON PERIODONTAL HEALING OF CONCOMITANT ENDODONTIC PERIODONTAL LESIONS

INTRODUCTION:

Although deleterious effects of endodontic tissue on the periodontium are well documented, the converse effect of periodontal disease on pulp remains unclear. There is abundance of research on the avenues of communication but still many doubts exist. High prevalence of accessory canals has been seen but not all primary endodontic lesions drain through the periodontal ligament. Many endodontic lesions are more prone to drain through cortical bone rather than through the periodontal ligament. It may be because of the nature of periradicular lesions which initially try to expand horizontally through cancellous bone and then progressing vertically. Evidence also suggests that endodontically treated teeth lack the same proprioceptive capability as endodontically untreated teeth so they may be subjected to greater occlusal forces. More forces could enhance the propagation of fracture lines along the root surface, resulting in more periodontal attachment loss. Also teeth associated with either root perforations or fractures appear to follow periodontal drainage routes whereas lesions of primarily pulpal origin seem to remain localized or drain through cortical bone. Many explanations are provided, firstly periodontal ligament may be resistant to bacterial insult of endodontic origin, or injuries originating through mechanical trauma are faintly recognized, causing a subtle attachment loss occurring secondary to routine endodontic disease. Another explanation could be that the main or accessory canals might not be the solo and most important route of communication and endodontic infection might also proceed along cervically located dentinal tubules.

Current Primary Outcome: Improvement in periodontal parameters Probing depth [ Time Frame: baseline to 6months ]

periodontal parameters pocket depth (in mm) was measured at baseline to 6 months with the help of calibrated manual periodontal probe.
