Abstract

Objectives: Occlusal alterations may result in changes in thefunctional performance of masticatory muscles. This studywas planned to evaluate mandibular elevator muscles ofpatients with dental attrition by using ultrasonography(USG).Materials and Methods: 30 physiologically dental attritionsubjects, aged 35–65 years, were clinically examined bytooth wear index (TWI). Patient group (TWI scores of 2–4)and age-matched controls (TWI scores of 0–1) underwentultrasonographic analysis to assess the thickness of anteriortemporalis, superficial masseter muscles, bilaterally, duringclench and rest positions.Results: The mean thickness of masseter and temporalmuscles for rest and clench positions and the ratio betweenthickness of clench and rest position (C/R) were evaluated.Muscle thickness had a higher mean value in the tooth weargroup. However, the only significant differences were in theC/R ratio for left side of masseter (p=0.04) and temporalmuscles (p=0.03). Although, there was a negative correlationbetween TWI scores and the muscle C/R ratio for the toothwear group. A significant positive correlation was foundbetween age and TWI in both groups.Conclusion: The contraction capacity of the chewingmuscles and the attrition mutually interact. This studyshowed an associate on between the severity of occlusaltooth wear and the C/R of chewing muscles. Although dentalattrition can occur due to increased jaw muscle activation,and it can also cause a reduction in the contraction capacityof mandibular elevator muscles.

Özet

Amaçlar: Okluzal değişiklikler çiğneme kaslarının fonksiyonel performansında değişikliklere neden olabilir. Bu çalışma ultrasonografi (USG) ile dental atrizyonu olan hastaların mandibular elevator kaslarını değerlendirmek amacıyla planlanmıştır. Gereç ve Yöntemler: 35–65 yaşları arasında 30 adet fizyolojik atrizyonu olan hasta, diş aşınma indeksi (TWI) kullanılarak klinik olarak incelendi. Hasta grubu (2–4 TWI skorları) ve yaş eşleştirilmiş kontroller (0–1 TWI skorları), anterior temporal ve yüzeysel masseter kaslarının, bilateral olarak, diş sıkma ve dinlenme pozisyonları sırasında kalınlığını değerlendirmek amacıyla ultrasonografik analizi yapıldı. Bulgular: Dinlenme ve diş sıkma pozisyonları için masseter ve temporal kasların ortalama kalınlığı ve diş sıkma ile dinlenme pozisyonu (C / R) arasındaki oran değerlendirildi. Kas kalınlığı, atrizyon grubunda daha yüksek bir ortalama değere sahipti. Bununla birlikte, tek anlamlı fark masseter kasın sol tarafında C / R oranında (p = 0,04) ve temporal kaslarda (p = 0,03) bulundu. Bununla birlikte, TWI skorları ile atrizyon grubu için kas C / R oranı arasında negatif bir korelasyon vardı. Her iki grupta yaş ve TWI arasında anlamlı pozitif korelasyon bulundu. Sonuç: Çiğneme kaslarının kasılma kapasitesi ve atrizyon karşılıklı olarak etkileşmektedir. Bu çalışmada, okluzal diş aşınmasının şiddeti ile çiğneme kaslarının C/ R' si arasında ilişki bulunmuştur. Çiğneme kaslarının aktivitesinin artması nedeniyle atrizyon meydana gelebilir ve bu da mandibular elevatör kasların kasılma kapasitesinde azalmaya neden olabilir.
