Title: Comparative Evaluation of Maxillary and Mandibular Anterior Teeth Width with the Length of Index and Little Fingers among Sudanese Population
Author: Mohamed, Nada Fathalla Abdelbagi Abdelbagi
Abstract: Background: The primary concern for patients seeking prosthodontic treatment is aesthetics. The mesiodistal width of the anterior teeth is important because they are the most prominent teeth in the arch when viewed from the frontal aspect. Various methods have been suggested for selecting the size of the anterior teeth like bizygomatic width, and intercanine width. The anthropometric measurements like finger length can serve as a basic guide in estimating the size of anterior teeth in males and females when pre extraction records are not available. Materials and Methods: This was a cross sectional study performed at the University of Khartoum and enrolled in 150 dental students. Both males and females were included, with age ranged from 18 to 25 years old. Data were collected using a meter tape for measuring the mesiodistal width of the maxillary and mandibular anterior teeth and an acrylic finger device for recording the length of the index and little fingers. Pesrson Correlation Coefficient test was used for the correlation between the study variables and the regression analyses was used to predict the appropriate equations. All statistical analyses were set at p-value < 0.05. Results: The mean width of the maxillary anterior teeth for the whole sample was (5.5 ± 0.5) while the mean width of the mandibular anterior teeth for the whole sample was (4.2 ± 0.3). The mean length of the index finger was (7.2 ± 0.5) while the mean length of the little finger was (5.9 ± 0.5). The following formulas could be applicable to all Sudanese: The Maxillary anterior teeth width can be calculated from the formula (3.207 + length of index finger X 0.312. Mandibular anterior teeth width can be calculated with the formula (16.608 + length of little finger X 0.496). Conclusion: Significant correlation between the maxillary and mandibular anterior teeth width with the length of the index and little finger. The length of the index finger can be used to predict the width of the maxillary anterior teeth while the length of the little finger can be used to predict the width of the mandibular anterior teeth.
