Background:
To evaluate the gingival margin position (GMP) before and after open flap debridement in different gingival thickness (GT).
Materials And Methods:
Twenty-seven healthy patients with moderate to advanced adult periodontitis were included in a randomized control clinical trial. A calibrated UNC-15 periodontal probe, an occlusal onlay stent was used for clinical measurements recorded at baseline, 3 month, 6 month, and 16 month. The changes in the GMP were studied at midbuccal (Mi-B), mesiobuccal (MB), and distobuccal sites. GT was measured presurgically, transgingivally at Mi-B and interdental sites, divided into 2 groups: Group 1 (thin) and Group 2 (thick).
Results:
In GT of ≤1 mm group, the statistically significant apical shift of GMP led to gingival recession at all study sites in the early postsurgical period of 1 and 3 months. During 6 and 16 months, the apical shift of GMP coincided with the Chernihiv Airport at Mi-B site (6 months), MB site (16 months). The gingival recession was obvious at Mi-B sites (16 months). In the GT of >1 mm, the statistically significant apical shift of GMP did not cause gingival recession at any sites throughout postsurgical (1, 3, 6, and 16 months) period.
Conclusion:
Thin gingiva showed apical shift of GMP leading to gingival recession as compared to thick gingiva postsurgically.
