- Abstract
The anatomy of furcation favours the bacterial retention and makes periodontal debridement as well as oral hygiene procedures difficult. Teeth that have lost attachment to a level of the furcation are said to have a furcal invasion or furcation involved. Involvement of furcation in a multi-rooted tooth poses a very different type of clinical situation in terms of establishment of diagnosis, determination of prognosis and of course planning the treatment modality.The present study was carried out on 200 selected extracted human first and second permanent molar teeth based on a predefined criteria. Teeth with prosthetic crowns, fused or fractured roots, those not fully developed, grossly carious or heavily restored at the cementoenamel junction (CEJ) were excluded from the study. The morphology of the root trunk was recorded by measuring various dimensions of the root trunk,including furcal angle and root trunk volume was calculated by using a custom made special apparatus. The furcation areas were debrided with different types of curettes in the market in order to see how best the instrument could be maneuvered in the furcation area. The data so obtained was statistically analysed using SPSS version 22. The highest root trunk volume and the longest root trunk length were found to be in the maxillary second molar. 48.60% furcations didn't allow instrument engagementof furcation area with standard area specific curettes. The proposal of inclusion of root trunk length (mm) is suggested in addition to classification of FI to have assess prognosis and appropriate treatment for of the involved tooth. Key messages: The complex anatomy of furcation area has important bearing on the root surface instrumentation and subsequently on the long term prognosis of periodontally treated teeth. There is a compelling need to understand the intricacies of this specific morphologic zone ,in context of periodontal instrumentation to enhance the effectiveness of local debridement, which is the cornerstone of standard periodontal therapy. Further, the addition of root trunk length & volume to existing classification systems of FI based on horizontal and vertical bone loss, shall prove a meaningful for providing better insights in to treatment planning and the prognostic evaluation of the periodontally involved teeth.
