Dişli ve Posterior Kısmi Dişsiz Hastalar Arasında Masseter Kas Kalınlığının ve Mandibulanın Morfolojik Özelliklerinin Karşılaştırılması

Abstract

Amaç: Dişli ve posterior kısmi dişsiz hastaların masseter kas kalınlıkları ve mandibular morfolojilerinin karşılaştırılmasıydı. Gereç ve Yöntemler: 40-60 yaş arası 90 kadın hasta, dişli ve posterior dişsiz olmak üzere ikiye ayrıldı. Çalışmaya katılan bireylerin herhangi bir iskelet kas hastalığı, bruksizm alışkanlığı yoktu. Kontrol grubu ve bilateral posterior dişsiz hastalarda ölçümler çift taraflı yapıldı ve sağ sol taraf ölçümlerinin ortalamaları alındı. Tek taraflı posterior dişsiz hastaların sadece dişsiz olan tarafları ölçüldü. Masseter kası kalınlığını değerlendirmek için, ultrasonografi ile, istirahat ve ısırma pozisyonlarında, aynı gözlemci tarafından beş dakika aralıklarla iki kez ölçüm yapıldı. Mandibular morfolojinin yorumlanması için, panoramik radyograf üzerinde gonial ve antegonial açılar ölçüldü. Aynı gözlemci bir hafta sonra ikinci kez ölçümlerini tekrarladı. Bulgular: Masseter kası kalınlığı ile posterior kısmi dişsizlik arasında herhangi bir anlamlı ilişki bulunamadı (ısırma durumunda p=0,793, serbest durumda p=0,962). Pearson korelasyon testi sonuçlarına göre hem kontrol hem çalışma grubunda gonial açı ile masseter kas kalınlığı arasında anlamlı bir negatif korelasyon vardı (-0,402≤r≤-0,375). Sonuç: Posterior kısmi dişsizlik, masseter kas kalınlığında anlamlı bir azalmaya neden olmamıştır. Masseter kasının fonksiyonel aktivitesi, gonial bölgenin şekillenmesinde etkilidir. Ultrasonografi, masseter kası kalınlığının değerlendirilmesinde güvenilir, doğru ve tekrarlanabilir bir yöntem olarak bulunmuştur. Anahtar kelimeler: Antegonial açı, Gonial açı, Masseter kası, Panoramik radyograf, Ultrason.

Comparison of Masseter Muscle Thickness and Morphological Properties of Mandible Between Dentulous and Partially Posterior Edentulous Patients

Abstract

Background: The aim of this study was to investigate the relationship between thickness of masseter muscle and mandibular morphology of dentulous and partially posterior edentulous patients. Methods: 90 female patients between the ages of 40 and 60 were divided into two groups: control dentulous group and posterior edentulous group. Patients had no musculoskeletal systemic disease and no bruxism habit. The measurements of control group and bilateral posterior edentulous patients were performed bilaterally and the averages of right and left were obtained. Only the toothless side of unilateral edentulous patients was measured. Ultrasonography was used to examine the thickness of the masseter muscle, during rest and maximum voluntary contraction, twice with five minutes intervals by the same observer. Gonial and antegonial angles were analysed on panoramic radiography to evaluate mandibular morphology, twice with one week interval by the same observer. Results: There was no statistically significant association between masseter muscle thickness and posterior partially edentulism (bite position p=0,793, relax position p=0,962). The results of the Pearson’s correlation test showed that masseter muscle thickness in both control and experimental groups was negative correlated with the gonial angle (-0,402≤r≤-0,375). Conclusion: Posterior partially edentulism does not reason a significant decrease of masseter muscle thickness. The functional activity of masseter muscle is influential in the formation of the gonial region. Ultrasonography is found to be a reproducible, reliable and accurate tool to examine the thickness of the masseter muscle.
