Background/Aim: Emergency physicians are among the first healthcare professionals to manage traumatic dental injuries, yet knowledge deficiencies may compromise early care. This study evaluated emergency physicians' knowledge of traumatic dental injury management, ToothSOS awareness, and factors independently associated with overall knowledge. Materials and Methods: This questionnaire-based cross-sectional study was conducted among emergency physicians in Turkey between April 2 and May 19, 2026. The survey assessed demographic and professional characteristics, traumatic dental injury knowledge, ToothSOS awareness, and willingness to use the application. Item-level associations were analyzed using chi-squared or Fisher's exact tests. An overall knowledge score, ranging from 0 to 8, was analyzed using univariable comparisons and multivariable linear regression. Factors associated with willingness to use ToothSOS were evaluated using multivariable logistic regression. Results: A total of 208 emergency physicians were included. Correct-response rates ranged from 47.1% for the first intervention for an avulsed permanent tooth to 91.8% for identifying the most commonly affected teeth. ToothSOS awareness was 1.0%, although 79.6% of unaware participants stated they would consider using the application. The mean overall knowledge score was 5.23 ± 1.48. Previous dental trauma training and clinical exposure to traumatic dental injury cases were associated with higher scores in univariable analyses; only clinical exposure remained an independent predictor after adjustment. No factor independently predicted willingness to use ToothSOS. Conclusions: Emergency physicians demonstrated moderate overall traumatic dental injury knowledge, with deficiencies in avulsion management and referral decisions. Previous clinical exposure to such cases was the only independent predictor of higher knowledge scores, supporting structured training rather than reliance on incidental experience. Low ToothSOS awareness, despite high willingness to use it, supports integrating dental trauma education and digital decision-support tools into emergency medicine training and clinical protocols.

İncele - MakaleAçık Erişim2023Scopus SJRQ2Assessment the impact of operator experience on cyclic fatigue resistance in reciprocating and rotary NiTi files: a comparative study between dental students and pediatric dentistry specialists

Introduction: Devices reducing clinical practice time, and which get minimally affected by user experience are invaluable in pediatric dentistry. Additionally, knowing the fracture resistance of different nickel-titanium (NiTi) files for root canal preparation of primary teeth is important for treatment success. Thus, the present study aimed to compare the instrumentation time (IT) and fracture resistance of reciprocating T-endo MUST (TEM) and continuously rotating AF Baby File (ABF) NiTi files according to the use of pediatric dentistry specialists. Methods: According to their clinical experience level, 3 experimental groups (EG)s were formed namely: no experience, 2-years (less-experienced), and 10-years experienced pediatric dentistry specialists' groups. The fourth group was the control group (CG). In each EGs, 10 TEM (25/.06) and 10 ABF 20/.04, and 10 ABF 25/.04 NiTi file systems were used in 20 artificial resin teeth. Instrumentation time was recorded for each tooth. In the CG, the same number of files were not used for instrumentation. The files in all groups were subjected to a dynamic cyclic fatigue test, and the data were analyzed using the Kruskal–Wallis test at 5% significance level. Results: In all groups, TEM files showed a significant higher fatigue resistance as compared to ABF files. However, fatigue resistances were significantly lower in (EG)s both in TEM and ABF compared to (CG)s. The instrumentation time was found to be significantly lower in TEM compared to the ABF. Also, for both file systems, the experience level did not affect the fatigue resistance, and instrumentation time. Discussion: The experience level of the pediatric dentist did not affect the cyclic fatigue resistance of the reciprocating and rotating NiTi files, but the instrumentation time was lower for the reciprocating NiTi files.
