This study aimed to determine the degree of discrepancy between clinical measurement of furcation involvement (FI) and cone beam computed tomography image analysis of multirooted teeth.
FI measurements obtained from clinical records were compared to CBCT images of the same teeth to determine the degree of discrepancy between CBCT FI grading and clinical FI grading.
Of the hundred and fifty-four sites analysed, 22% of FI measurements from probing and CBCT were in agreement. Fifty-eight percent of clinical FI recordings were overestimated, and 20% were underestimated when compared to CBCT analysis.
Clinical recording of FI is both over and underestimated compared to CBCT analysis. This was highest for probing recording grade I furcation involvement where it was highly overestimated. The occurrence of over and under estimation of FI will affect the assignment of prognosis to multirooted teeth, which can influence treatment planning for periodontal therapy and may result in inappropriate treatment.
本研究旨在确定多根牙临床测量的根分叉病变（FI）与锥形束计算机断层扫描图像分析之间的差异程度。
将临床记录中获得的FI测量值与同一牙齿的CBCT图像进行比较，以确定CBCT FI分级与临床FI分级之间的差异程度。
在分析的154个部位中，探诊和CBCT的FI测量值有22%一致。与CBCT分析相比，58%的临床FI记录被高估，20%被低估。
与CBCT分析相比，FI的临床记录既有高估也有低估。对于探诊记录为I度根分叉病变的情况，高估最为严重。FI的高估和低估情况会影响多根牙的预后判定，进而影响牙周治疗的治疗计划，可能导致不恰当的治疗。
