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

Abstract

Background: Radiographs in periodontics will provide a two-dimensional image of a three-dimensional object and this leads to problems in terms of validity, accuracy and precision. Hence, the study was conducted with an aim to assess the accuracy of IOPA And CBCT for Maxillary Molar Furcation involvement by clinical and radiological methods.Methods: The study sample consisted of 17 subjects from the Out patient Department of A.J. Institute of Dental Science, Manglore belonging to both sexes and with age ranging from 35-55 years. The selected patients were those having presence of periodontal pockets of >5-6mm and advanced periodontal disease requiring surgical intervention. For the purpose of standardization, 3 sites of the maxillary first molars were assessed-Mid-buccal, Mesio-buccal, Disto-buccal. Iopa and CBCT measurements were taken which was followed by surgical intervention during which probing measurements were recorded. Statistical analysis was done using ‘unpaired t test’.Results: There was no statistically significant difference between CBCT measurements and surgical measurements (p≤0.05).Conclusions: CBCT accurately reproduced the clinical measurement of periodontal bone defects.

Assessment of alveolar bone level and furcation involvement in periodontal diseases using dental cone-beam computed tomography (CBCT): a systematic review

“…Specific furcal parameter investigated in the study included horizontal bone loss at furcation entrance level, maximum horizontal bone loss, maximum vertical bone loss and root trunk length. The accuracy of CBCT measurements were in furcation involvement was further reinforced by results obtained in studies conducted by Parvez MF et al and Sreih R et al [22,25] In a study conducted by Aghanashini S et al the furcation areas were grades from I-III during clinical, intra-surgical and CBCT assessment. This methodology was different from majority of studies, which tended to measure the dimensions of furcation involvement rather than grade the furcation defect [20].…”

“…Endodontic file and assessed with a digital vernier caliper , Nabers probe and UNC 15 probe were the armamentarium used for the intrasurgical evaluation of periodontal defects in the clinical studies listed in our systematic review (12)(13)(14)(15)(16)(17)(18)(19)(20)(21)(22)(23)(24)(25)(26). While most of the researchers used Nabers probe and UNC 15 probe for measurement of bony defects Padmanabhan S et al used a combination of endodontic files and digital vernier caliper [19].…”

Role of CBCT in Periodontal Diagnosis; Mandatory or Overkill

“…While CBCT images have shown greater accuracy while co-relating to direct measurements no significant differences have been reported between CBCT and conventional periodontal diagnosis. [6,7] Indiscriminate use of CBCT for routine periodontal diagnosis and care thus continues to be excessive. However specific clinical situations may warrant their use as has been outlined below:…”

Furcation From Clinical and Periodontal Perspectives

“…The radiographic gold standard for diagnosing FI is CBCT. A diverse number of studies compared CBCT with presurgical and intra surgical (IS) measurements and found CBCT having agreeable or better accuracy compared to probing and intra-surgical measurements [12][13][14][15]. RadioVisioGraphy (RVG) is a 2D digital imaging aid that projects the image directly in the monitor.…”
