Association of Transgingival Probing with CBCT Evaluation for Determination of Biotype of the Gingiva

Aims: The study aimed for determination of correlation between transgingival probing and CBCT evaluation, for the determination of gingival biotype.

Study Design: Cross-sectional study.

Place and Duration of Study: Department of Periodontics, Fatima Memorial Hospital, Lahore and 17th August 2016 to 16th February 2016.

Methodology: In this cross-sectional study, a total of 40 patients indicated to undergo implant placement for posterior maxillary teeth or any mandibular teeth, 18 to 50 years were included. Patients with the presence of restoration in the anterior maxilla, pregnant or lactating women, root canal treatment in the anterior maxilla, and h/o apical surgery were excluded. A single radiologist examined the CBCT obtained from all of the patients. Linear measurements for buccal wall & gingival biotype were measured.

Results: The mean age was 35.13 ± 7.75 years. Of the 40 subjects, there were 22 (55.0%) females and 18 (45.0%) males. On CBCT, the radiographic measures were 1.49 0.34 mm for the right central and 1.49 0.34 mm for the left central. There is a statistically significant link between transgingival probing and CBCT examination for determining gingival biotype, with a Spearman's correlation coefficient of 0.985 and a p-value of 0.0001.

Conclusion: According to the findings of this study, there is a substantial positive association between transgingival probing and CBCT measures of gingival biotypes.
