Abstract

Objective: Dentistry is widely recognized as an ergonomically challenging profession, with work-related musculoskeletal disorders (WMSDs) often developing early during undergraduate education. While physical workload is heavily studied, how preclinical education affects body awareness and pain sensitivity remains unexamined. This prospective observational study aimed to investigate concurrent changes in self-reported musculoskeletal discomfort, subjective body awareness, and objective pressure pain thresholds (PPT) among third-year dental students during their initial 14-week preclinical training, thereby demonstrating how early ergonomic conditions affect the human body. Method: Thirty-two voluntary, consenting third-year dental students (17 females, 15 males) were prospectively investigated at baseline and at the end of a 14-week preclinical semester. Students with a history of surgery, congenital musculoskeletal anomalies, or chronic diseases were excluded from the study. Subjective parameters were evaluated using the Body Awareness Questionnaire (BAQ) and the Cornell Musculoskeletal Discomfort Questionnaire (CMDQ). Objective tissue hypersensitivity and pain thresholds were mapped via a Baseline® mechanical dolorimeter across validated myofascial trigger points. Statistical significance was set at p<0.05. Results: Following the 14-week curriculum, participants experienced a significant increase in total musculoskeletal discomfort, with CMDQ scores surging significantly (p<.001). Importantly, there was a marked decline in body awareness, as BAQ scores significantly decreased (p<.001). In parallel, algometric tests revealed significant declines in PPT across every tested muscle group throughout the body (p<.001). Conclusion: Preclinical dental practice induced musculoskeletal disorders and impaired body awareness are fully initiated during the earliest stages of dental training. In conclusion, proper ergonomic approaches and preventive rehabilitation strategies must be established during the undergraduate dental education period.

Özet

Amaç: Diş hekimliği, işe bağlı kas-iskelet sistemi hastalıklarının sıklıkla lisans eğitimi sırasında geliştiği, ergonomik açıdan zorlayıcı bir meslektir. Çalışmalarda hekimlerin fiziksel iş yükü incelenmiş, ancak lisans döneminde preklinik dönemin vücut farkındalığı ve ağrı hassasiyeti üzerindeki etkileri henüz araştırılmamıştır. Bu çalışma, üçüncü sınıf diş hekimliği öğrencilerinde ilk 14 haftalık preklinik eğitimlerinin başlangıcında ve sonunda, kas-iskelet sistemi rahatsızlığı, vücut farkındalığı ve objektif basınç ağrı eşiklerindeki (BAE) eşzamanlı değişimleri incelemeyi ve böylece erken dönemdeki ergonomik koşulların vücudu nasıl etkilediğini ortaya koymayı amaçladı. Yöntem: Çalışmaya katılmaya gönüllü olan ve bilgilendirilmiş onam veren 32 üçüncü sınıf diş hekimliği öğrencisi (17 kadın, 15 erkek) başlangıçta ve 14 haftalık preklinik dönem sonunda prospektif olarak incelendi. Cerrahi öyküsü, doğuştan kas-iskelet sistemi anomalisi veya kronik hastalığı olan öğrenciler çalışmadan dışlandı. Subjektif parametreler Vücut Farkındalığı Anketi (VFA) ve Cornell Kas İskelet Sistemi Rahatsızlık Anketi (CKİSR) kullanılarak değerlendirildi. Artmış doku hipersensitivitesi ve basınç ağrı eşikleri (BAE), miyofasiyal tetik noktaları üzerinden Baseline® marka mekanik dolorimetre aracılığıyla değerlendirildi. İstatistiksel analizlerde anlamlılık düzeyi p<0.05 olarak kabul edildi. Bulgular: On dört haftalık müfredatın ardından katılımcıların CKİSR skorlarının anlamlı şekilde yükselmesiyle (p<.001) toplam kas-iskelet sistemi problemlerinde anlamlı bir artış bulundu. Ek olarak, VFA skorlarının anlamlı derecede düştüğü (p<.001) ve vücut farkındalığında belirgin bir azalma olduğu görüldü. Paralel olarak algometrik testler, vücut genelinde değerlendirilen her kas grubunda BAE değerlerinde anlamlı düşüşler ortaya koydu (p<.001). Sonuç: Preklinik dönem diş hekimliği uygulamalarının tetiklediği kas-iskelet sistemi bozuklukları ve bozulan beden farkındalığı diş hekimliği eğitiminin henüz en erken aşamalarında başlamaktadır. Sonuç olarak, doğru ergonomik yaklaşımların ve önleyici rehabilitasyon stratejilerinin lisans diş hekimliği eğitimi sürecinde planlanması gerekmektedir.
