Background:The purpose of this study was to assess the efficacy of hyaluronic acid (HA) in root coverage procedures as an adjunct to coronally advanced flap (CAF) procedure.Materials and Methods:This was a randomized clinical trial with split mouth design, where 10 patients with 20 sites of Millers Class I recession were treated and followed-up for a period of 6 months. CAF procedure was performed, HA was applied onto the experimental sites before suturing the flap. Recession depth (RD) was measured regularly at baseline 1, 3, 6, 12, and 24 weeks postoperatively. Probing pocket depth (PPD) and clinical attachment level (CAL) were also measured along with RD at baseline and 12 and 24 weeks.Results:There was a significant change in RD, PPD, CAL, and percentage of root coverage in both groups when compared to the baseline values. There was no statistically significant difference between experimental and control group in terms of RD (P = 0.917), PPD (P = 0.917) and CAL (P = 0.761). RD was 3.2 mm ± 0.78 mm in experimental site and control sites 2.9 mm ± 0.73 mm reduced to 1.1 mm ± 0.99 mm in experimental sites and 1.0 mm ± 0.66 mm in control sites. Though, there is no statistically significant difference root coverage in the experimental group appeared to be clinically more stable compared with the control group after 24 weeks.Conclusions:This study suggests that use of HA may improve the clinical outcome of root coverage with CAF procedure.

IntroductionA smile is an expression denoting pleasure, sociability, happiness or amusement and can reflect self-confidence of an individual. A smile seems to have a favorable influence upon others and makes one likeable and more approachable. The beauty of a smile is not only influenced by how the teeth and lips look, but also by the way gingival tissue appears. A dark or black colored gum is one of the concerns of patients reporting to dental clinics. Dark pigmentation of the gum usually occurs due to excessive melanin deposition in gingival epithelium. Melanin pigmentation of the gingiva is a physiologic process that occurs in all ethnicities.1 The prevalence of melanin pigmentation varies between 0% to 89% in different populations with regard to ethnic factors and tobacco usage. Gingival hyperpigmentation is termed as physiological or racial pigmentation, as it occurs as a genetic trait in some populations.3 Gingival hyperpigmentation in patients with gummy smile or excessive gingival display could pose an esthetic problem. Gingival depigmentation is a periodontal plastic procedure carried out by various techniques like conventional scalpel technique, gingivec- Abstract Introduction: Dark or black coloured gingiva is an esthetic concern especially in subjects with high lip line or gummy smile. Gingival depigmentation procedure is a type of perioplastic surgery where the gingival epithelium is excised with various techniques to lighten the colour of the gingiva. The aim of this study was to compare the clinical efficacy of gingival depigmentation procedure with conventional scalpel technique and diode laser application. Methods: This split mouth randomized study was conducted on 12 subjects (18-40 years of age), exhibiting melanin hyperpigmentation of gingiva. The anterior labial sextant of maxilla and mandible were divided into two halves involving three anterior teeth i.e. central incisor, lateral incisor and canine on each side. The divided areas were randomly allotted for depigmentation procedure either with scalpel technique or diode laser operating at 980 nm wavelength. Various parameters such as bleeding, pain, difficulty of procedure and wound healing were assessed and compared between the two techniques. The level of melanin pigment was assessed with Dummette Gupta index and photographic analysis with the help of adobe software. The subjects were followed up to one year to see for recurrence of melanin pigmentation. Results: Bleeding during surgery, pain score and difficulty of procedure assessed by the operator were statistically higher for scalpel technique as compared to laser technique. Wound healing did not show any statistical significant difference between both techniques. Gingival depigmentation ...
Objective: The objective of present study was to compare the efficacy of 0.2% chlorhexidine and 0.25% sodium hypochlorite as a mouthwash in controlling chronic gingivitis.Methods: A total of 80 patients suffering from chronic marginal gingivitis were recruited for the study. Non-surgical periodontal therapy was completed for all the patients to bring the gingival status to healthy levels. The patients were divided into two study groups with 40 patients in each group, Group A patients were asked to use 0.2% chlorhexidine mouthwash, and Group B patients used 0.25% sodium hypochlorite mouthwash as an adjunct to brushing twice daily for 2 weeks. After a period of 2 weeks, the gingival status was recorded using the oral hygiene index simplified (OHIS), plaque index (PI), and modified gingival index (MGI) and compared between the two groups.
Results:The mean OHIS score for Group A was 1.38 and for Group B it was 1.05. The mean PI for Group A and B was 3.62 and 2.32, respectively. The mean MGI score for Group A was 1.22 and for Group B was 1.20. Group B showed better results than Group A. Intergroup comparison of OHIS and PI revealed significantly better results in Group B than Group A while MGI did not show any statistical difference on comparison.Conclusion: Nearly 0.25% sodium hypochlorite was more effective than 0.2% chlorhexidine in reducing the gingival inflammation. Thus, 0.25% sodium hypochlorite may represent an efficacious, safe and affordable antimicrobial agent in the prevention and treatment of gingival disease.
Introduction: Dentinal Hypersensitivity (DH) is one of the most commonly encountered clinical problems. Literature reveals no specific therapy to satisfactorily eliminate dentinal hypersensitivity.
