    Assessment of health technician students' awareness of dental trauma in Turkey
    (Bmc, 2026) Altintas, Elif Defne; Kurt, Sebnem Sarioglu; Ozatik, Sebnem; Ozturk, Aysegul
    Background Traumatic dental injuries (TDIs) require prompt and appropriate emergency management. In Turkey, university-affiliated Health Services Vocational Schools train auxiliary healthcare personnel who may be first responders in such cases. However, the extent of their knowledge on dental trauma remains unclear. This study aimed to assess the awareness regarding TDI emergency management among students enrolled in university-affiliated Health Vocational Schools in Turkey, and to determine whether these levels differ between academic years. Methods A cross-sectional survey was conducted among 333 students from 16 programs across 7 vocational schools. Participants completed a 17-item online questionnaire assessing demographic data and dental trauma knowledge. Six key knowledge questions were classified based on the International Association of Dental Traumatology (IADT) guidelines. Descriptive and inferential statistics were used (p < 0.05). Results Only 7.2% of students reported receiving first aid training that included dental trauma content. A majority (78.7%) felt their knowledge was insufficient, and 89.8% believed dental trauma education is necessary. While 21% reported knowing what to do in the event of tooth avulsion, only 38.1% selected an appropriate storage method. Second-year students showed a significantly higher rate of receiving first aid training (p = 0.001) and asking about tetanus vaccination status (p = 0.017) than first-year students. Significant differences were found in correct responses based on self-reported knowledge levels regarding tooth contamination (p = 0.001) and fractured tooth management (p = 0.025). Conclusions Health technician students in Turkey demonstrated limited knowledge about the emergency management of dental trauma. Integrating structured dental trauma education into vocational health curricula is recommended to improve early response and patient outcomes.

    Thermal, mechanical, and densification analysis of osteotomy drill designs for implant placement: an analysis on foam blocks representing type IV bone
    (Quintessence Publishing Co Inc, 2025) Ozturk, Aysegul; Arisan, Vokan; Rojas, Godoberto Guevara
    Objectives: To analyze the effects of three osteotomy drill designs (conventional, reverse helix, and densification) and running directions on heat generation, primary implant stability, block-to-implant contact, peri-implant block volume, and resistance to unscrewing forces in a low-density alveolar bone model. Method and materials: Eighty-eight dental implants were placed in artificial bone blocks using manual and computer-controlled osteotomies. Temperature changes, insertion torque value, resonance frequency analyses (implant stability quotient [ISQ]), block-to-implant contact, and peri-implant block volume were measured. Statistical analyses used ANOVA and Kruskal-Wallis tests (P <.05). Results: Densification drill designs produced the lowest temperature change (17.52 +/- 2.57 degrees C and 28.06 +/- 4.35 degrees C for the second and third drills), while conventional drills had the highest (27.53 +/- 5.17 degrees C and 38.03 +/- 8.08 degrees C). Counter-clockwise (CCW) conventional drilling significantly reduced the temperature change compared to clockwise (CW). Densification drill designs achieved the highest primary implant stability (38.01 +/- 1.87 N/cm, 65.00 +/- 4.69 ISQ) and removal torque (25.40 +/- 5.08 N/cm), while conventional CW drills had the lowest (33.23 +/- 2.91 N/cm, 61.83 +/- 4.28 ISQ). Densification drill designs showed the highest peri-implant block volume (87.71 +/- 4.23 mm3) but the lowest block-to-implant contact (49.12 +/- 2.93%). CCW conventional drilling improved insertion torque value over CW (36.21 +/- 3.63 vs 33.23 +/- 2.91 N/ cm). Conclusion: Densification drill designs demonstrated better performance in heat reduction, primary implant stability, and peri-implant block volume, but had lower block-to-implant contact. CCW running of conventional drills showed improvements over CW in several parameters. While densification drilling excelled in most aspects, its lower block-to-implant contact and the positive outcomes of CCW conventional drilling warrant further investigation.
