Aim: To assess the furcation entrance dimension (FED) in extracted maxillary 1st, 2nd and 3rd molars and to correlate the findings to periodontal instrumentation. Methodology: 103 teeth were included in the study and tooth type was determined. The sample consisted of 43 first, 34 second and 22 third maxillary third molars. Teeth were placed on a 1mm graph and photographs were taken on the buccal, mesial and distal aspects. Dimensional analysis was performed using Adobe Photoshop wherein various diameter circles were placed to scale with the most coronal aspect of the buccal, medical and distal furcations. The circles were placed such that they fit along the mesiodistal dimension on the inner aspect of the furcations. Result: Buccal furcations (0.76mm) were found to be narrower followed by distal (0.95mm) and mesial (0.96mm) furcations of maxillary molars. Mention the mean values in MM for each furcation. Also mention the average blade widths of specific Periodontal instruments besides curettes. in relation to the instruments, average blade width of the curretes 7-8 (0.75mm), 9-10 (0.75mm), 11-12 (1mm), 13-14 (0.75mm), 2R/2L (1mm), 4R/4L (1mm), piezoelectric ultrasonic scaler tip (0.5mm). 49% of 1st, 65% of 2nd and 73% of 3rd maxillary molars had furcation entrance dimension less than 0.75mm. Conclusion: Maxillary molars furcation entrances are not only difficult to access but are also ineffectively debrided with standard periodontal instruments much as piezoelectric ultrasonic tips and area-specific curettes. Furcations that are narrower than 0.75mm therefore require instruments that can access and diagnose furcation involvements. In addition, improvements and standardization of piezoelectric ultrasonic tips, periodontal curettes pertaining as well as rotary instruments should be considered to adequately eliminate local factors within narrow furcations.
