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.

Association of gingival exhibit with lip dimensions, intercommissural width, and gingival and interdental smile lines - a gender-based evaluation.

OBJECTIVE: The present study aimed to evaluate the gender-based association of gingival exhibit with lip dimensions, intercommissural width (ICW), interdental smile line (ISL), and gingival smile line (GSL) in periodontally healthy patients. MATERIALS AND METHODS: 120 patients aged between 20 and 40 years were divided equally into two groups based on gender. The parameters of lip length (LL) at rest and on smiling, ICW, and the intraoral parameters of gingival exhibit in ISL and GSL were measured on digitized photographs in the maxillary anterior teeth. RESULTS: The LL positions at rest and on smiling differed significantly: 23.50 ± 3.31 mm and 19.89 ± 1.91 mm, and 16.53 ± 2.94 mm and 13.91 ± 1.93 mm for males and females, respectively. The gingival exhibit of the interdental papillae in ISL was 3.01 ± 1.85 mm for males and 4.26 ± 1.85 mm for females, while the midfacial exhibit in GSL was 0.62 ± 1.01 mm for males and 1.24 ± 1.44 mm for females; both the differences were statistically significant. CONCLUSION: The gender variability in LL, the interdental papillae exhibit in ISL, and the midfacial exhibit in GSL can provide constructive guidelines that can be implemented in the esthetic zone.
