Abstract

The objectives of this study were to measure the Furcation Entrance Dimensions of first and second permanent molars in Malaysian samples and to compare the Furcation Entrance Dimensions with the blade widths of periodontal Gracey?s curette used for root surface instrumentation. A total of 199 extracted permanent teeth were measured, which comprised of 51 mandibular first molars, 51 mandibular second molars, 45 maxillary first molars and 52 maxillary second molars. Furcation Entrance Dimension was measured using calibrated test gauges. Results showed 51.91% of Furcation Entrance Dimension was <0.70mm. Forty eight percent (48.09%) of Furcation Entrance had Furcation Dimension of more than 0.70mm. It was concluded that 51.91% of all the Furcation Entrance Dimensions of these teeth were less than the blade width of new Gracey curettes. Therefore, new periodontal Gracey?s curette of small dimension may be the best choice of instrumentation and that ultrasonic debridement using a narrow tip may be a more appropriate choice.

Highlights

Methods for the treatment of furcation involving molars have been shown to have variation degrees of success.[1]
The result showed that 42.86% of buccal furcation for mandibular second molar and 41.18% of buccal furcation for mandibular first molar had an entrance dimension of
The results showed that 44.44% of the maxillary first molars and 71.15% of the maxillary second molars had Furcation Entrance Dimension of less and equal to 0.70mm (

Summary

Introduction

Methods for the treatment of furcation involving molars have been shown to have variation degrees of success.[1]. It has been shown to reduce the efficacy of periodontal therapy that had been found in multirooted teeth with furcal involvement, regardless of the treatment modality employed.[4,5] Molar root morphology influences the diagnosis, prognosis and treatment of periodontal disease.[6] Numerous studies have documented a high loss of maxillary and mandibular molars because of Corresponding author: Fouad Hussain Al-Bayaty periodontal disease[7]. This is due, at least in part to difficulty in instrumenting the furcation areas. The purpose of this study was to measure the Furcation Entrance Dimension in Malaysian first and second upper and lower permanent molars and to compare these dimensions with the blade of periodontal curettes which have been used in root debridement within furcation at the Faculty of Dentistry, University of Malaya
