METHODS: One hundred and forty dental students (age 21 to 42 years, mean 27.4 years) participated in the study. The ability of each subject to position 3 or 4 fingers, vertically aligned, between the upper and lower central incisors up to the first distal interphalangeal folds, was documented. Measurements of MMO and the width of 3 fingers (index, middle and ring fingers) and 4 fingers (index, middle, ring and little fingers) were recorded. RESULTS: All subjects were able to position 3 fingers (of both the right and left hands) between the upper and lower central incisors. Only 12 subjects were able to position 4 fingers (both right and left) in this way. There were no significant differences among the measurements of MMO (mean 48.8 mm), 3 fingers of the right hand (mean 47.3 mm) and 3 fingers of the left hand (mean 47.0 mm) (p > 0.05). However, MMO was significantly different from the width of 4 fingers of the right hand (mean 58.1 mm) and 4 fingers of the left hand (mean 57.5 mm) (p < 0.001). Moreover, there was a strong positive correlation between MMO and the 3-finger measurements (p < 0.0001). CONCLUSIONS: These findings strongly suggest that the ability to position 3 fingers in the mouth during dental examination is a convenient index for assessing normal MMO  ردمد : 1488-2159  اسم الدورية : J Can Dent Assoc  المجلد : 69  العدد : 11  سنة النشر : 2003 هـ 2003 م  نوع المقالة : مقالة علمية  تاريخ الاضافة على الموقع : Thursday, December 6, 2007  الباحثون اسم الباحث (عربي) اسم الباحث (انجليزي) نوع الباحث المرتبة العلمية البريد الالكتروني خالد زواوي Zawawi, Khalid باحث رئيسي دكتوراه kzawawi@kau.edu.sa الملفات اسم الملف النوع الوصف  An index for the measurement of normal maximum mouth opening.pdf pdf   الرجوع إلى صفحة الأبحاث
