Evaluation of the Effects of Diode (980 Nm) Laser on Gingival Inflammation after Nonsurgical Periodontal Therapy

Introduction: Periodontitis is an inflammatory disease, for which, scaling and root planning (SRP) is the common approach for non-surgical control of inflammation. Using lasers is another approach in the first phase of periodontal treatment for control of inflammation. Diode laser has some beneficial effects such as acceleration of wound healing, promotion of angiogenesis and augmentation of growth factor release. Thus the aim of this study is the evaluation of diode laser (980 nm) effect on gingival inflammation when it is used between the first and second phase of periodontal treatment, in comparison with common treatment (SRP) modality alone.Methods: In this study, 21 patients with moderate to severe chronic periodontitis were selected and divided in to control group (SRP) and test group (SRP + laser). Two months after the last scaling and laser radiation, indexes including gingival level (GL), bleeding on probing (BOP) and modified gingival index (MGI) were recorded and compared with baseline.Results: Two months after the beginning of the study, all indices improved in both groups. The indices were not different between two groups except for BOP which was lower in laser group.Conclusion: Based on overall improvement in parameters such as superiority of laser application in some indices, lack of thermal damage and gingival recession with the specific settings used in this study, the application of laser as an adjunctive treatment together with common methods is preferable

Health Literacy in Periodontal Patients

Introduction: health literacy is a fundamental part of the healing promotion. The aim of this study was to evaluate periodontal health literacy among patients. Materials and methods: 296 patients attending periodontal clinic who were above 16 years old participated in this study. Gathering data was based on screening questions on a 5-point Likert scale. After completion questionnaire, data was analyzed by Mann-Whitney and Kruskal-Wallis test. Based on the scores of questions, patients were classified as weak, medium and good health literacy. Result: This study showed significant difference in health literacy between age and education groups (P value = 0.015, P value = 0.003), while there was no significant difference between male and female (P value = 0.54). It was also revealed that patients who had been exposed to oral health education had higher health literacy levels ( P value < 0.0001, P value = 0.001). Conclusion: The results of this study showed patients less than 20 years and over 50 years old had poorer heath literacy in relation of periodontal heath, also, patients with higher educational level have higher health literacy

Clinical evaluation of the use of diode (980 nm) laser as an adjunct to traditional periodontal Treatment

Introduction: In periodontal pockets, the exposed root surfaces are contaminated with an accumulation of plaque and calculus. Usually, in the initial phase of periodontal therapy, debridement of the diseased root surface is non surgically. However, complete removal of plaque and calculus is not always achieved with only the use of conventional mechanical therapy. The outcome of other studies showed that adding diode laser therapy to the initial phase of periodontal therapy significantly improved treatment results. The aim of this study was the evaluation of the effects of diode (980 nm) laser on clinical periodontal parameters after nonsurgical periodontal therapy. Methods: Twenty-one patients with moderate to severe chronic periodontitis (11 men and 10 female with mean age of 42.2) were selected and divided into the control group (SRP) and test group (SRP + laser). Two months after the last scaling and laser radiation, clinical parameters were recorded and compared with baseline. This clinical trial study was in splint mouth design which was done on randomized selection in two quadrant (Maxilla and Mandible) in test group. the data were entered in computer and analysed bying SPSS 16 and Mannywhitny and Wilcoxon test. Results: After two months, clinical parameters improved in both groups. There were statically significant difference between two groups in PI and PD (0-3) mm, however in CAL and PPD (3-5) mm, (>5) mm no statically significant difference were seen. Conclusion: According to an overall improvement in clinical parameters, usage laser as an adjunctive treatment besides common methods could be suggested

Evaluation of the Effect of Surgical Crown Lengthening on Periodontal Parameters

Background: Surgical crown lengthening is needed for teeth with subgingival caries, fractured teeth, insufficient crown length, and deep subgingival margin of failed restorations. Since there is no agreement on the effects of crown lengthening surgery on gingival parameters, the purpose of this study was to evaluate periodontal parameters in patients who needed crown lengthening surgery. Methods: Twenty patients who had healthy periodontium and needed surgical crown lengthening were included in this study. After professional dental cleaning, gingival parameters including gingival index (GI), probing depth (PD), bone level (BL), and transsulcular probing (TSP) were recorded in interproximal and keratinized gingiva (KG) in mid buccal portion. The patients were evaluated one and three months after the surgery. Results: After one and three months of the surgery, the amount of PD reduced from 2.32 mm to 1.25 mm and 1.17 mm, respectively (P=0.001). The mean of BL reduction was 0.88 mm after one month (P=0.001), but there was no reduction between 1 month and 3 months. Amounts of KG at baseline andone month later were 4.2 mm and 2.9 mm, respectively (P=0.001), and remained at the same level up to three months. TSP significantly reduced (from 3.67 mm at baseline to 2.62 mm after 1 month, and to 2.27 mm after 3 months) (P=0.001, P=0.005). Conclusion: The present  study suggests that in the presence of good oral hygiene, except BW (biological width), other parameters including PD, BL, KG, and TSP had significant changes after crown lengthening surgery in the period of 1 month and 3 months (
