Publication Metadata only Evaluation of the Effectiveness of Er:YAG Laser and Conventional Periodontal Treatment in a Patient with Acute Streptococcal Gingivitis: A 2-Year Follow-Up(MARY ANN LIEBERT, INC, 2010) KADİR, TANJU; Gursoy-Mert, H.; Altan-Koran, M.; Noyan, U.; Kadir, T.; Cologlu, S.; Yilmaz, S.Objective:The aim of this study was to evaluate the effectiveness of Er:YAG laser and conventional periodontal therapy in the treatment of acute streptococcal gingivitis both clinically and microbiologically. Background Data:This case report describes a 2-year follow-up of a 30-year-old, female, chronic periodontitis patient, presenting severe gingival inflammation, sensitivity, pain, and acute gingival lesions that were treated with Er:YAG laser and conventional hand and ultrasonic instruments. Materials and Methods:Before the initial periodontal treatment, microbiological samples were taken from the lesion sites with sterile paper points from the sulcuses bilaterally, and excisional biopsies were obtained from the lesions. Following diagnostic tests, the lesions were identified as acute streptococcal gingivitis. Following the measurement of clinical indices, initial periodontal therapy was performed with Er:YAG laser on the right side and conventional hand and ultrasonic instruments on the left side, which were performed as two sessions at weekly intervals. As an adjunct to mechanical periodontal therapy, 500 mg amoxicillin was prescribed t.i.d. for a week. Results:Microbiological samples grew mostly Streptococcus sp. and black pigmented obligate anaerobic bacteria. The histopathological examination revealed acanthosis, papillomatosis, and spongiotic lesions in the keratinized stratified squamous epithelium; infiltration of polymorphonuclear neutrophils, lymphocytes, and macrophages and plasma cells in the connective tissue; infiltration and accumulation of polymorphonuclear neutrophils in the epithelium, especially in the spongiotic lesions; and formation of microabscess-like clusters. After the initial periodontal treatment, clinical and microbiological measurements were repeated and reductions in clinical indices and the number of microorganisms were observed. Both treatment modalities gave similar results, and no recurrences were observed during the 2-year follow-up. Conclusion:Er:YAG laser seems to be promising and as effective as conventional periodontal therapy in the treatment of acute streptococcal gingivitis.Publication Metadata only Er:YAG Laser Versus Systemic Metronidazole as an Adjunct to Nonsurgical Periodontal Therapy: A Clinical and Microbiological Study(MARY ANN LIEBERT INC, 2012) KADİR, TANJU; Yilmaz, Selcuk; Kut, Burak; Gursoy, Hare; Eren-Kuru, Bahar; Noyan, Ulku; Kadir, TanjuObjective: The objective of this randomized clinical trial was to describe the clinical and microbiological results obtained by treatment with Er:YAG laser and systemic metronidazole used as adjuncts to mechanical subgingival debridement in chronic periodontitis. Methods: Twenty-seven chronic periodontitis (CP) patients were randomly divided into three parallel groups each comprising nine individuals with at least four teeth having at least one approximal site with a probing depth (PD) of >= 5 mm and gingival index (GI) of >= 2 in each quadrant. Groups of patients received: (1) Scaling and root planing (SRP) + Er:YAG laser (10 hz, 30 mJ/pulse, 1 min per pocket, apico-coronal direction in parallel paths with 30 degree angle tips, under water irrigation), (2) SRP + systemic metronidazole, or (3) SRP alone. In all treatment groups, SRP was performed at 1 week intervals in two sessions. The microbiological and clinical effects of the treatments were evaluated after 90 days. Results: At the end of the experimental period, statistically significant improvements in plaque index, GI, PD and attachment level, as well as reductions in the number of total bacteria and proportions of obligately anaerobic microorganisms were observed within each group. Although intergroup comparisons revealed no significant microbiological differences, clinical parameters as attachment gain and PD reduction were found significantly higher in Group 1 compared with the other groups. Conclusions: Within its limits, this study demonstrated the possibility of better resolution of infection with combined SRP + Er: YAG laser treatment. However, microbiological results failed to demonstrate significant advantages of this combination in comparison with SRP alone or SRP + systemic metronidazole.Publication Metadata only Evaluation of the Clinical and Antimicrobial Effects of the Er:YAG Laser or Topical Gaseous Ozone as Adjuncts to Initial Periodontal Therapy(MARY ANN LIEBERT INC, 2013) KADİR, TANJU; Yilmaz, Selcuk; Algan, Serdar; Gursoy, Hare; Noyan, Ulku; Kuru, Bahar Eren; Kadir, TanjuObjective: The aim of this study was to evaluate the clinical and microbiological results of treatment with the Er:YAG laser and topical gaseous ozone application as adjuncts to initial periodontal therapy in chronic periodontitis (CP) patients. Background data: Although many studies have evaluated the effectiveness of the Er:YAG laser as an adjunct to initial periodontal therapy, few studies have focused on the use of gaseous ozone as an adjunct. Materials and methods: Thirty patients with CP were randomly divided into three parallel groups, each composed of 10 individuals with at least four teeth having at least one approximal site with a probing depth (PD) of >= 5mm and a sulcus bleeding index (SBI) >= 2 in each quadrant. Groups of patients received: (1) Scaling and root planing (SRP) + Er:YAG laser; (2) SRP + topical gaseous ozone; or (3) SRP alone. The microbiological and clinical parameters were monitored at day 0 and day 90. Results: At the end of the observation period, statistically significant improvements in clinical parameters were observed within each group. Parallel to the clinical changes, all treatments reduced the number of total bacteria and the proportion of obligately anaerobic microorganisms. Although intergroup comparisons of microbiological parameters showed no significant differences, clinical findings, including attachment gain and PD reduction, were found to be statistically significant in favor of the SRP + Er:YAG laser group. Conclusions: Although statistically nonsignificant, the fact that the obligate anaerobic change was mostly observed in the SRP+ Er:YAG laser group, and a similar decrease was noted in the SRP + topical gaseous ozone group, shows that ozone has an antimicrobial effect equivalent to that of the Er:YAG laser.Publication Metadata only Er:YAG Lasers Versus Ultrasonic and Hand Instruments in Periodontal Therapy: Clinical Parameters, Intracrevicular Micro-organism and Leukocyte Counts(MARY ANN LIEBERT, INC, 2012) KADİR, TANJU; Malali, Ezgi; Kadir, Tanju; Noyan, UlkuObjective: The aim of this study was to compare the clinical parameters and crevicular cell population, particularly leukocyte counts, changes after initial periodontal therapy with different instruments by a chairside laboratory technique, in severe periodontitis patients. Background data: Although scaling and root planing (SRP) with hand curettes or ultrasonic scalers may alter the subgingival microbial composition and improve clinical parameters, it is known that this effect decreases as the pocket depth (PD) increases. Material and methods: Thirty systemically healthy subjects with severe chronic periodontitis were randomly assigned to three groups (n = 10), and were treated either with hand curettes, ultrasonic scalers, or Er:YAG laser alone. Clinical measurements were made before and 90 days after treatment. A total of four subgingival plaque samples were collected from pockets with a PD 4-6 and >= 7 mm and were analyzed with a phase-contrast microscopy for microorganism proportions and leukocyte counts at baseline and 7 and 90 days after treatment. Results: From day 0 to day 90, clinical parameters were significantly improved in all groups (p < 0.01), but there were no significant differences among groups. Laboratory assessments revealed significant differences in all groups between baseline, day 7, and day 90. However, considering changes from day 7 to day 90, hand curettes were the most successful for maintaining the levels of micro-organisms and leukocytes. Conclusions: Although Er:YAG lasers are promising in treating periodontitis, the results of this study favor finishing SRP with hand curettes. Moreover, as there is a similar tendency between micro-organism and leukocyte count changes, leukocyte counts may be used as chairside marker to evaluate the efficacy of SRP.
