Evaluation of accuracy of cone beam computed tomography for measurement of periodontal defects: A clinical study

Abstract

Aims:The aim of the present study was to evaluate the accuracy of Cone Beam Computed Tomography (CBCT) measurements of alveolar bone defects caused due to periodontal disease, by comparing it with actual surgical measurements which is the gold standard.Materials and Methods:Hundred periodontal bone defects in fifteen patients suffering from periodontitis and scheduled for flap surgery were included in the study. On the day of surgery prior to anesthesia, CBCT of the quadrant to be operated was taken. After reflection of the flap, clinical measurements of periodontal defect were made using a reamer and digital vernier caliper. The measurements taken during surgery were then compared to the measurements done with CBCT and subjected to statistical analysis using the Pearson's correlation test.Results:Overall there was a very high correlation of 0.988 between the surgical and CBCT measurements. In case of type of defects the correlation was higher in horizontal defects as compared to vertical defects.Conclusions:CBCT is highly accurate in measurement of periodontal defects and proves to be a very useful tool in periodontal diagnosis and treatment assessment.

Comparative assesment of accuracy of IOPA and CBCT for maxillary molar furcation involvement: a clinical and radiological study

“…15 However, evaluation of the type and depth of the defect during surgery gives little time to the surgeon to plan out the type of procedure for periodontal regeneration. 16 Radiographs are valuable diagnostic tools which act as an adjunct to clinical examination. On subsequent radiographic examinations bone loss or gain may be assessed by comparing subsequent radiographs to the initial radiographs.…”

“…Banodkar et al, conducted a similar study to evaluate the accuracy of CBCT in the detection of alveolar bone defects by comparing it with surgical methods. 16 Hundred periodontal bone defects in fifteen patients were included in the study. There was high correlation between surgical and CBCT measurements which proved that CBCT was highly accurate in the measurement of periodontal defects.…”

Tomografia computadorizada no planejamento cirúrgico em Periodontia: revisão de literatura

“…A TCFC demonstrou ser confiável na medição de defeitos ósseos alveolares 12,13,16,29,30 e na avaliação de envolvimentos de furca, apesar de alguns estudos terem encontrado discrepâncias entre as medições da TCFC e as medições transcirúrgicas diretas. Um fator a ser considerado é que existe uma grande variação entre os estudos com relação ao software utilizado na análise das imagens e a ao tamanho do voxel da digitalização para as medições.…”

“…Banodkar et al 12 avaliaram a precisão da TCFC nas medições de defeitos ósseos alveolares causados pela doença periodontal, comparando-as com medidas cirúrgicas reais, que é o padrão-ouro. Cem defeitos ósseos periodontais em quinze pacientes, que sofriam de periodontite e agendados para cirurgia de retalho, foram incluídos no estudo.…”

Role of Cone Beam Computed Tomography in Dentistry

“…Since the advent of CBCT in various fields of dentistry, various studies have been conducted to evaluate the potential of this technique in periodontics, and mixed results have been obtained. CBCT has been found to be accurate to sub millimeter levels in measuring horizontal bone loss [22]. Three dimensional quantitative information on periodontal bone levels has been reported to be slightly better than conventional radiography.…”
