A novel soft tissue cone-beam computed tomography study in the evaluation of gingival thickness associated with subepithelial connective tissue graft versus acellular dermal matrix in the management of gingival recession: A clinical study

Comparative evaluation of pinhole surgical technique with and without A-PRF in the treatment of multiple adjacent recession defects: A clinico radiographic study

BACKGROUND

To evaluate and compare efficacy of pinhole surgical technique (PST) alone and with advanced platelet rich fibrin (A-PRF) in the management of bilateral multiple adjacent gingival recession defects (MAGRD).

METHODS

One hundred and sixty five MAGRD were randomly assigned to control group (treated with PST) and test group (PST with A-PRF). Clinical parameters of gingival recession depth (GRD), gingival recession width (GRW), width of keratinised gingiva (WKG), complete root coverage (CRC) and gingival thickness (GT) on ST-CBCT was measured at 2, 4 and 6 mm apically from the gingival margin. Also, root coverage aesthetic score and patient satisfaction ratings were recorded at baseline, 6 and 12 months postoperatively.

RESULTS

Substantial reduction in GRD (Test: 1.29 ± 0.69 mm and Control 0.98 ± 0.30 mm) (p < 0.001) and GRW (Test: 2.03 ± 0.90 mm and control 1.73 ± 0.99 mm) (p < 0.05) with associated gain in WKG and GT was observed (p < 0.001). Mean GT values were increased in both the groups at 2, 4 and 6 mm from the crest. Comparison of Test and Control groups yielded significant reductions in GRD (-0.17 ± 0.56 mm) and WKG (0.73 ± 1.07 mm) favoring the Test group (p < 0.05). Similar increase in GT was observed with better results in Test than control group. (p < 0.001).

CONCLUSION

Both groups exhibited sound clinical outcomes with test group offering better resolution of MAGRD in comparison to control group. Also, it enhances clinical and therapeutic end results in terms of attaining reduction in GRD and GRW along with greater gain in KTW and GT.

CLINICAL SIGNIFICANCE

PST as a minimally invasive approach has numerous benefits, some of which include the absence of scarring and improved aesthetics linked to faster wound healing. The addition of A-PRF enhances the intended therapy outcomes, which is beneficial for both patients and professionals in the field of periodontics.

A Comparative Evaluation of Dentogingival Tissue Using Transgingival Probing and Cone-Beam Computed Tomography

Background and Objective: Gingival biotype can be assessed using a variety of invasive and non-invasive procedures, such as direct probing, transgingival probing, ultrasound-guided approaches, and, for the more sophisticated, cone-beam computed tomography. The aim of this study was to evaluate gingival biotype in relation to transgingival probing and cone-beam computed tomography (CBCT). Materials and Methods: This study included a total of two hundred healthy individuals. Gingival thickness was assessed and measured from the right and left maxillary central incisor teeth using CBCT and transgingival probing of the attached gingiva. The measurements were analyzed with regard to tooth type (central incisor). Linear measurements for gingival biotype were measured using both methods. Correlations and differences between measurement methods were assessed. Results: The mean age of study participants was 32.49 ± 8.61 years. The radiographic measurements on CBCT were 1.34 ± 0.17 mm for the right central and 1.28 ± 0.21mm for the left central. The transgingival probing measurements were 1.31 ± 0.18 for the right central and 1.22 ± 0.21mm for the left central. Conclusion: As per the results of this study, there is a significant positive correlation between transgingival probing and CBCT measurements of gingival biotypes.
