AIM: To analytically determine the furcation entrance dimensions of extracted permanent mandibular first, second and third molar teeth with relation to periodontal instruments used in the furcation. MATERIALS AND METHODS: 114 extracted permanent mandibular molars were collected and segregated into first, second and third molars post decontamination and debridement. Each tooth was placed on a 1mm paper grid and photographs of the buccal and lingual aspects were taken using a DSLR camera. The furcal entrances were measured using Adobe photoshop wherein circles of 0.25mm diameter were drawn to scale to the grid. These circles were drawn adjacent to each other in one plane to measure the mesiodistal aspect at the highest aspect of the furcation. The values obtained were compared to that of the diameters of the working ends of periodontal instruments commonly used in the furcation. RESULTS: 13% of mandibular first molars and 51.7% of mandibular second molars had furcation entrance dimension less than 0.75mm which is lesser than the blade width of standard curettes. Only ultrasonic scaler tips would fit in the furcations of 34.5% of mandibular second molars. All mandibular third molars evaluated in this study had fused roots with fluting and only Naber’s probe and ultrasonic tips would engage the furcations. CONCLUSION: The complexity of molar furcation areas provides a challenge for periodontal treatment that can lead to increased tooth loss compared to other tooth types. Standard hand curettes generally advocated for root surface instrumentation are standardized based on Caucasian populations and thus may show variation while instrumenting. An under instrumented furcation entrance provides a nidus for plaque accumulation and periodontal infection, greatly affecting the prognosis and treatment outcomes.
