Öğe Applying nano-HA in addition to scaling and root planing increases clinical attachment gain(Korean Acad Periodontology, 2022) Uysal, Ozge; Ustaoglu, Gulbahar; Behcet, Mustafa; Albayrak, Onder; Tunali, MustafaPurpose: This study evaluated the efficacy of treating periodontitis using subgingival nano-hydroxyapatite powder with an air abrasion device (NHAPA) combined with scaling and root planing (SRP). Methods: A total of 28 patients with stage III periodontitis (grade B) were included in this study, although 1 was lost during follow-up and 3 used antibiotics. The patients were divided into a test group and a control group. All patients first received whole-mouth SRP using hand instruments, and a split-mouth approach was used for the second treatment. In the test group, the teeth were treated with NHAPA for 15 seconds at 70% power per pocket. Subgingival plaque samples were obtained from the 2 deepest pockets at the test and control sites before treatment (baseline) and 3 months after treatment. The full-mouth plaque index (PI), gingival index (GI), papillary bleeding index (PRI), bleeding on probing (BOP), probing depth (PD) and clinical attachment level (CAL) were recorded at baseline and at 1- and 3-month post-treatment. Real-time polymerase chain reaction was used to determine the colonisation of Treponema denticola (Td), Porphyromonas,gingivalis(Pg), and Aggrega Odder actinomycelemcomitans in the subgingival plaque. Results: From baseline to the first month, the test group showed significantly larger changes in BOP and CAL (43.705%+/- 27.495% and 1.160 +/- 0.747 mm, respectively) than the control group (36.311%+/- 27.599% and 0.947 +/- 0.635 mm, respectively). Periodontal parameters had improved in both groups at 3 months. The reductions of PI, GI, BOP, PD, and CAL in the test group at 3 months were greater and statistically significant. The total bacterial count and Td and Pg species had decreased significantly by the third month in both groups (P<0.05). Conclusions: Applying NHAPA in addition to SRP improves clinical periodontal parameters more than SRP alone. Subgingival NHAPA may encourage clot adhesion to tooth surfaces by increasing surface wettability.Öğe Authors’ response(Faculdade De Odontologia De Bauru, 2022) Saglam, Ebru; Ozsagir, Zeliha Betul; Unver, Tugba; Alinca, Suzan Bayer; Toprak, Ali; Tunali, Mustafa[No abstract available]Öğe Management of Deep Gingival Recessions by Modified Coronally Advanced Tunnel Technique with Titanium Platelet Rich Fibrin Membrane or Connective Tissue Graft: 36 Months Follow-up Clinical Study(Marmara Univ, Inst Health Sciences, 2020) Koyuncuoglu, Cenker Zeki; Ercan, Esra; Uzun, Bilge Cansu; Tunali, Mustafa; Firatli, ErhanObjective: The goal of the study is to evaluate the results of Titanium-Platelet Rich Fibrin (T-PRF) membrane and Connective Tissue Graft (CTG) with modified coronally advanced tunnel technique (MCATT) in treatment of deep gingival recession defects. Methods: Twenty-one systemically healthy patients displaying 62 Miller Class I/II gingival recession defects >= 3.0 mm in depth, treated either with MCATT with CTG or with T-PRF membrane were included in this retrospective study. The periodontal parameters were assessed at baseline, and at 6 and 36 months after surgery. The percentages of the mean root coverage (MRC) and complete root coverage (CRC) were calculated. Results: The probing depth values were decreased at 36 months according to baseline values for both groups (p<0.05). Keratinized tissue (KT) was increased at 6 months according to baseline for both groups (from 1.69 +/- 0.74 mm to 3.61 +/- 0.67 mm for T-PRF; and 3.40 +/- 1.60 mm to 4.52 +/- 2.33 for CTG). The 36th month measurement of KT showed an increase in the T-PRF group compared to the 6th month measurement, while the CTG group showed a significant decrease (3.86 +/- 0.76 mm and 2.76 +/- 1.45 mm, respectively). The CRC ratios were 80% and 56% at 6 and 36 months, respectively for the CTG group. However, this ratio remained the same (64.86%) for the T-PRF group. There was statistically significant difference between CRC ratios of both groups at 36 months (p<0.05). Conclusion: T-PRF membrane with MCATT procedure is as predictable as CTG with MCATT for management of deep gingival recessions. However, future prospective studies about this topic with a split-mouth design are needed.Öğe Nano-Hydroxyapatite Airborne-Particle Abrasion System as an Alternative Surface Treatment Method on Intraorally Contaminated Titanium Discs(Quintessence Publishing Co Inc, 2020) Gumus, Kerem Caglar; Ustaoglu, Gulbahar; Kara, Levent; Ercan, Esra; Albayrak, Onder; Tunali, MustafaThe aim of this study was to test the nano-hydroxyapatite powder decontamination method on intraorally contaminated titanium discs and to compare this method with current decontamination methods in the treatment of peri-implantitis. Contaminated discs were assigned to six treatment groups (n = 10 each): titanium hand curette; ultrasonic scaler with a plastic tip (appropriate for titanium); ultrasonic scaler with a plastic tip (appropriate for titanium) + H2O2; short-term airflow system (nano-hydroxyapatite airborne-particle abrasion for 30 seconds); long-term airflow system (nano-hydroxyapatite airborne-partide abrasion for 120 seconds); Er:YAG laser (120 mJ/pulse at 10 Hz). There were also two control groups (n = 10 each): contaminated disc (negative control) and sterile disc (positive control). Scanning electron microscopy, energy-dispersive x-ray spectroscopy, and dynamic contact angle analysis were used to determine the most effective surface-treatment method. The highest percentage of carbon (C) atoms was observed in the negative control group, and the lowest percentage of C atoms was found in the long-term airflow group, followed by the short-term airflow, laser, ultrasonic + H2O2, ultrasonic, and mechanical groups. When the groups were examined for wettability, the lowest contact angle degree was observed in the long-term airflow, short-term airflow, and laser groups. Nano-hydroxyapatite and laser treatments for detoxifying and improving infected titanium surfaces may show the most suitable results for reosseointegration.
