An In Vitro Evaluation Of Deepest Portion Of Furcal Groove In Maxillary First Premolars Before And After Instrumentation With Stainless Steel Hand Files And Two Niti Rotary File Systems Under CBCT

Abstract

The objective of this study is to perform a morphometric assessment of the buccal furcation grooves in bifurcated maxillary first premolars and to evaluate anatomical measurements before and after operative procedures using three different file systems: stainless steel K file, Wave One, and NeoEndo file, utilizing CBCT imaging.

Method: 99 extracted human bifurcated maxillary first premolars were selected, and an initial CBCT scan was conducted. Dentin cementum wall thickness at the mid-groove area was measured prior to instrumentation. Subsequently, access cavity preparation was performed. The teeth were then randomly allocated into three groups, with 33 teeth in each group. The first group underwent instrumentation with a stainless steel (SS) K-file up to apical size 25 with a 2% taper, the second group with a Neoendo flex file (NF) up to apical size 25 with a 4% taper, and the third group with a WaveOne (WO) primary file size 25 with an 8% taper. Following instrumentation, a post-operative CBCT scan was conducted, and dentin cementum wall thickness was re-measured at the same location.

RESULT: When compared the dentine removed after instrumentation in the furcal groove is more in WaveOne file (0.24mm) followed by stainless steel file (0.154 mm) and Neoendo file (0.148 mm)

CONCLUSION : Dentin removed at furcal groove region is more in waveone file compared to stainless sttel files and neoendo files
