The outcomes of the present study suggest that both regenerative approaches yielded significant improvements in both clinical and radiographic assessments. The procedure using a collagen membrane in combination with a bone substitute showed better results at 12 months in RST of peri-implantitis.

PurposeThe decontamination procedure is a challenging aspect of surgical regenerative therapy (SRT) of peri-implantitis that affects its success. The purpose of the present study was to determine the impact of additional topical gaseous ozone therapy on the decontamination of implant surfaces in SRT of peri-implantitis.MethodsA total of 41 patients (22 males, 19 females; mean age, 53.55±8.98 years) with moderate or advanced peri-implantitis were randomly allocated to the test group (ozone group) with the use of sterile saline with additional ozone therapy or the control group with sterile saline alone for decontamination of the implant surfaces in SRT of peri-implantitis. Clinical and radiographic outcomes were evaluated over a period of 12 months.ResultsAt the 12-month follow-up, the plaque and gingival index values were significantly better in the ozone group (P<0.05). Probing depth decreased from 6.27±1.42 mm and 5.73±1.11 mm at baseline to 2.75±0.7 mm and 3.34±0.85 mm at the end of the 12-month observation period in the ozone and control groups, respectively. Similarly, the clinical attachment level values changed from 6.39±1.23 mm and 5.89±1.23 mm at baseline to 3.23±1.24 mm and 3.91±1.36 mm at the 12-month follow-up in the ozone and control groups, respectively. According to the radiographic evidence, the defect fill between baseline and 12 months postoperatively was 2.32±1.28 mm in the ozone group and 1.17±0.77 mm in the control group, which was a statistically significant between-group difference (P<0.05).ConclusionsImplant surface decontamination with the additional use of ozone therapy in SRT of peri-implantitis showed clinically and radiographically significant.

Objectives To compare the 3-year clinical and radiographic outcomes of two different reconstructive surgical management of peri-implantitis using a bone substitute in combination with either concentrated growth factor (CGF) or collagen membrane (CM). Material and methods Fifty-one patients who had at least one implant presenting peri-implantitis with an intrabony defect were filled with a xenogenic bone grafting material and covered either CGF or CM. Clinical and radiographic assessments were carried out at baseline and postoperative years 1 and 3. Three different composite outcomes were defined to evaluate treatment success at a 3-year follow-up. The effects of possible prognostic indicators on treatment success were identified by using multilevel regression analysis. Results The changes in probing depth (PD) and radiographic vertical defect depth (VDD) between baseline and year 1 and baseline and year 3 presented significantly greater decreases for the CM group in comparison with the CGF group (p < 0.05). No significant differences between the two treatment modalities were demonstrated regarding treatment success outcomes. History of periodontitis, VDD at baseline, and the number of intrabony defect walls revealed significant impacts on treatment success (p = 0.033; OR = 3.50, p = 0.039; OR = 0.975, and p = 0.024; OR = 7.0 and p = 0.019;OR = 6.0, respectively). Conclusions CM in combination with a bone substitute seems to have slightly better outcomes compared to the CGF membranes in reconstructive surgical therapy of peri-implantitis. The history of periodontitis, baseline VDD, and peri-implant bone defect configuration could be possible predictors influencing treatment success. Trial registration ClinicalTrials.gov NCT04769609. Clinical relevance For the reconstruction of peri-implant bone defects, using a bone substitute in combination with a collagen membrane may show more favorable outcomes.

The purpose of this study was to examine the relation between sibling relationships, life satisfaction, and the loneliness level of adolescents with regard to gender, order of birth, and sibling dyads. The study group consisted of 382 (209 female, 173 male) students in total, who were studying at high schools (regular high school, vocational high school, Anatolian High School, private colleges) selected from Karşıyaka District in the city of İzmir, Turkey. The data collection tools used were the Life Span Sibling Relationship Scale, Life Satisfaction Scale, and Ucla Loneliness Scale III. The multivariate analysis of variance (MANOVA) was used for the analysis of data. The results from the research demonstrated that gender, birth order, and sibling dyads led to significant differences in life satisfaction, level of loneliness, and sibling relationships. In line with the results obtained from the research, it could be recommended that sibling relationships in the Turkish culture should be examined in terms of various age groups and different variables, and their psychosocial consequences should be subject to research.

Yeni koronavirus hastalığı (COVID-19) Dünya Sağlık Örgütü tarafından 11 Mart 2020 tarihinde pandemik bir hastalık olarak ilan edilmiştir. Vakaların ülkemizde görülmesiyle birlikte başta sağlık çalışanları olmak üzere risk altındaki bireylerin korunmasıyla ilgili birçok kaynaktan çeşitli bilgiler paylaşılmaya başlanmıştır. Hastalıktan korunmada gereken sosyal mesafenin diş hekimliği uygulamalarında sağlanamaması ve klinik işlemler sırasında oluşan aerosol ve damlacıklar yoluyla COVID-19'dan sorumlu SARS-CoV-2'nin bulaşma olasılığı nedeniyle diş hekimlerinin yüksek risk grubunu oluşturduğu öngörülmektedir. Bu derlemede, diş hekimliğinde COVID-19 bulaşma riskleri, genel korunma prensipleri, elektif tedaviler dışındaki acil tedavi sınırlarının neler olduğu ve diş hekimliği hastaneleri ve kliniklerinde konuya ilişkin mali ve etik sorunlar güncel literatür eşliğinde irdelenmiş ve öneriler getirilmiştir.
