A bstract Objectives Türkiye has implemented an open-door policy for Syrians since the beginning of the Syrian crisis in 2011 and has been providing medical and dental services for Syrian asylum seekers. Bursa, being the 5th largest city in the Western region of the Turkish Republic, hosts 1,83,355 registered Syrians. The present study was designed to analyze the caries-related dental services and preventive applications among 5-, 12-, and 15-year-old Syrian patients admitted to a state-affiliated dental hospital in Bursa, Türkiye. Design This study comprises retrospective data analysis. Place and duration of study The data from 1 st January 2016 to 1 st September 2021 were derived from the Bursa Oral and Dental Health Training and Research Hospital. Materials and methods The dental records of Syrian patients aged 5, 12, and 15 years were reviewed for caries-related (restorations, extractions, and root canal treatments) and preventive applications (fissure sealants and topical fluoridation); others were excluded. Results A total of 3,388 dental records of 1,179 Syrian children aged 5 (N = 369), 12 (N = 498), and 15 (N = 312) years were analyzed. The highest percentages of dental services offered to 5-, 12-, and 15-year-old were “tooth extractions” ( n = 369; 42.2%), “fissure sealants” ( n = 555; 33.7%), and “restorative treatments” ( n = 384; 44.4%), respectively ( p < 0.001). Considering all years (2016–2021), male subjects [odds ratio (OR)—1.42, 95% confidence interval (CI) 1.09–1.85; p = 0.01] and 12-year-old (OR—1.87, 95% CI 1.31–2.66; p = 0.001) were more likely to visit a dentist more than once per year. Conclusion Caries-related dental services, which are an indicator of poor oral health, are common in 5-, 12-, and 15-year-old Syrian patients.

Objectives: The aim of this study was to evaluate the effect of two different repair methods (Er:YAG laser and bur) with or without silane application on the microtensile bond strength of a nanohybrid resin composite aged with two different aging methods (pH cycling and thermocycling). Material and Method: Resin composite blocks (Clearfil Majesty Esthetic, Kuraray, Japan) were randomly assigned into two groups for aging process: (a) pH cycling (b) thermocycling (5,000 cycles). After aging, the blocks were assigned to one of the following repair procedures: (1) Er:YAG laser (LightWalker STE-E, Fotona Medical Lasers, Ljubljana, Slovenia) (2) Er:YAG laser+silane (3) bur (4) bur+silane and (5) no-pretreatment group and (6) Cohesive control (cohesive strength of the resin). Resin composite (Clearfil Majesty Esthetic) was bonded to the conditioned substrates incrementally and light polymerized. Repaired samples were thermocycled (5.000 cycles). The microtensile bonding test was performed. The data were analyzed using Scheirer-Ray-Hare, Kruskal-Wallis Mann-Whitney U tests, Chi-square and Z tests with Bonferroni correction (p=0.05). Results: No statistically significant difference was found between the aging methods applied to filling material (p=0.821) and the interaction of applied surface treatments and aging (p=0.289). All repair procedures achieved bond strength values higher than the no-pretreatment group but they did not reach the resin composite’s cohesive bond strength. Failure modes distribution was found statistically different according to repair procedure and also aging methods (p

Objective: Vaccines were considered as one of the most important public health measures during the coronavirus disease 2019 (COVID-19) pandemic. The aim of this study was to quantify and compare restorative dental practices of geriatric patients during pre-pandemic, prevaccination, and post-vaccination periods. Materials and Methods: Dental records of patients aged older than 65 who presented to Bursa Oral and Dental Health Training and Research Hospital were included in the study. Restorative dental practices during the three periods: pre-pandemic period (01.01.2019−10.03.2020), pre-vaccination period (11.03.2020−13.02.2021) and post-vaccination period (14.02.2021−01.09.2021) were reviewed according to the patient's age (young-old, middle-old and old-old), sex, tooth number (anterior and posterior), restoration type (occlusal, proximal, or cervical) and the type of restoration material (amalgam or composite).Results: Anterior restorations accounted for more than half (53%) of all restorations in the pre-COVID-19 pandemic period and 46.5% and 55.4% of restorations in the pre-and post-vaccination periods, respectively. The distribution of posterior amalgam restorations in the prepandemic period (31.5%) was higher than the pandemic period; in contrast, the composite restorations were higher during the pandemic pre-vaccination (73.9%) and post-vaccination (76.3%) periods (p<0.001). The males (odds ratio (OR): 1.17, 95% CI: 1.03-1.34, p=0.02) and middle-old (OR: 0.79, 95% CI: 0.64-0.96, p=0.019) were more likely to use restorative dental services as compared to females and youngold age, respectively. Conclusion:Vaccination had a noticeable effect on increased admissions of geriatric patients and restorative dental treatments compared to the pre-vaccination period. In addition, in the post-COVID-19 vaccination period, composite restorations seem to have replaced amalgam restorations.
