Abstract
Aim: This study aimed to evaluate the efficacy of dehydrated amnion allograft with coronally positioned flap procedure in paired Miller's class I recession defects.Methods: A total of 51 subjects were included in the study with bilateral Miller's class I gingival recession defects. In the test group, patients were treated with an amniotic membrane (AM) with a coronally positioned flap, while in the control group, patients were treated with coronally positioned flap alone. Clinical parameters such as recession depth, recession width (RW), probing depth (PD), relative attachment level (RAL), width of keratinized gingiva (WKG), and thickness of keratinized gingiva (TKG) were recorded at baseline and after 5 years of follow-up.Result: The mean baseline recession was 2.95 ± 0.89 in the test group and 2.70 ± 0.85 in the control group, and both were statically non-significant. At the end of 6 months, all the parameters, when compared with the baseline, showed a significant improvement. Intergroup comparison showed the non-significant difference in all settings except the TKG.Conclusion: AM proved to help improve the TKG. This increase in thickness helps in the long-term maintenance of the gingival margin in Miller's class I recession defect.
Highlights
The gingival recession is one of the most significant public health issues [1]
Intragroup data after 6 months (Table 2) showed that healing about Recession depth (RD), Recession width (RW), clinical attachment level (CAL), and width of keratinized gingiva (WKG) in both the groups was highly significant when compared with baseline
The test group showed a higher gain in the thickness of keratinized gingiva (TKG) when compared to baseline and was statistically significant (2.46 ± 0.22, p = 0.0001), whereas there was a non-significant gain in the control group (1.80 ± 0.16, p = 0.3382)
Summary
The gingival recession is one of the most significant public health issues [1]. A gingival recession usually exhibits an esthetic problem, primarily when it affects the anterior region of oral cavity. It is very often associated with dentinal hypersensitivity, root caries, and cervical abrasion due to the exposure of the root surfaces to the oral environment and an increase in plaque accumulation [3]. The prevalence of gingival recession is different in different parts of the world [4]. In India, the prevalence of gingival recession ranges from 24.29 to 67.23% [5]
