Background:Conventional, non-surgical periodontal therapy consists of supra- and subgingival tooth debridement. However, it is a technically demanding procedure and is not always efficient at eradicating all periodontal pathogens and in reducing inflammation. Therefore, local subgingival application of other chemotherapeutic agents may be used as an adjunct to non-surgical therapy. The aim of this study was to investigate the clinical and histological outcomes of local subgingival application of 0.2% hyaluronic acid gel (GENGIGEL®) as an adjunct to scaling and root planing (SRP) in chronic periodontitis patients.Materials and Methods:One hundred and twenty sites were chosen from 26 patients with chronic periodontitis (criteria being periodontal pockets ≥5mm). Experimental sites additionally received HA gel subgingivally at baseline, 1st, 2nd, and 3rd week. Clinical parameters were re-assessed at 4th, 6th, and 12th week. At 4th week recall, a gingival biopsy was obtained from test and control site for histologic examination.Results:Intra-group analysis of all the clinical parameters at all sites from baseline to 4th, 6th, and 12th week showed statistically significant changes. Experimental sites showed statistically significant improvement in Gingival index and Bleeding index at 6th and 12th week when compared with control sites. However, no statistically significant differences were observed in the PPD and RAL between control and experimental sites at 4th, 6th, and 12th week time interval. No statistically significant association was found between the histological grading of the sites that received HA treatment.Conclusion:Subgingival placement of 0.2% HA gel along with SRP provided a significant improvement in gingival parameters. However, no additional benefit was found in periodontal parameters. Histologically, experimental sites showed reduced inflammatory infiltrate, but it was not statistically significant.

We conclude that the biologic width of the DGU in humans can be measured with the PPRx technique. The values obtained agree with the values obtained by transgingival probing, a technique considered standard so far. Thus, the PPRx technique offers a simple, concise, noninvasive, and reproducible method that can be used in the clinical setup to measure both the length and thickness of the DGU with accuracy.

Gingival enlargement is quite a common pathology in pediatric patients and may be inflammatory, noninflammatory, or a combination of both. Idiopathic gingival fibromatosis, although rare, is a slowly progressive benign enlargement that affects the marginal gingiva, attached gingival, and interdental papilla. The fibromatosis may potentially cover the exposed tooth surfaces, causing esthetic and functional problems. The treatment of gingival fibromatosis is essential because it causes difficulties with mastication, speech problems, mispositioning of teeth, esthetic effects, and psychological difficulties for the patient. Traditional gingivectomy procedures have been a challenge for dentists who confront issues of patient cooperation and discomfort. In the last decade, laser procedures in oral cavity had shown many optimum effects in both hard and soft tissue procedures. Laser soft-tissue surgery has been shown to be well accepted by children. The following case report describes a laser-assisted gingivectomy procedure performed on a 13-year-old female.
