Objectives: To determine the anterior and overall Bolton’s ratio in the Sudanese population, investigate gender differences in tooth size ratios, and to compare these results with Bolton’s original ratio norm. Material and Methods: The sample consisted of dental casts of 104 Sudanese University students with normal occlusion (52 females, 52 males), aged between 16-26 years randomly selected from AL- Neelain University. An electronic digital caliper was used to measure the mesiodistal tooth size of the maxillary and mandibular teeth anterior to the second molars. These measurements were then used to obtain Bolton’s ratio. Mean, range, and standard deviation of the anterior and overall ratios were computed for each subject. T-Tests were used to compare gender differences and to i...

The purpose of this study is to analyze the mandibular dental arch forms of Sudanese adults with normal occlusion and provides an easy method for orthodontists to determine different types of arch form. Methods: This Descriptive analytical, cross-sectional study determined the mandibular arch in a sample of 104 Sudanese university students. Measurements were done in the mandibular dental cast. Three arch widths and three arch lengths measurements were established and five ratios were determined. Analysis of arch form was done according to Raberin’s polynomial method. Results: The mid arch form was the most prevalent (75%), followed by narrow arch form (11.54%), ...

Materials and Methods: This descriptive, analytical, cross-sectional study determined the mandibular arch in a sample of 104 Sudanese university students. The measurements were collected from the mandibular dental cast, established three arch width and three arch length measurements, and determined five ratios. The arch form was analyzed according to Raberin’s polynomial method. Results: The mid arch form was the most prevalent (75%), followed by the narrow arch form (11.54%), wide arch form (6.73%), and pointed arch form (6.73%). No case had flat arch form. Conclusion: Four types of arch forms were recognized in Sudanese subjects. Norms of transverse and sagittal dimensions of the mandibular arch to determine types of the mandibular arch form in Sudanese orthodontic patients were established.

Material and methods: A sample of 312 university students, were selected and divided into normal, crowded, and spaced groups. Each group included 104 students with equal males to females ratios. Age was ranged from 16 to 26 years. Mesiodistal (MD) tooth width of all teeth (except molars), arch perimeters, and dimension at the level of intercanine, interpremolar, and intermolar were measured for each group. ANOVA and student t-test were performed for the comparison between groups. Results: The MD dimensions of all teeth are greater in crowded arches as compared to the teeth in normal dental arches, except for the width of the maxillary, left second premolar in females, and mandibular left second premolar in male. Spaced arches were presented with significantly smaller MD width in all teeth when compared to normal arches, except for the width of maxillary right second premolar, maxillary left first premolar, mandibular right and left second premolars in female, and maxillary right second premolar in male. Crowded arches exhibit the largest total tooth material followed by normal and spaced dentition. Spaced arches show the widest arch dimension and perimeters followed by normal and crowded dentitions. Conclusions: Both tooth size and arch dimensions contribute to dental crowding and spacing. Clinical relevance: Since the size of the teeth and dental arches affect the space availability of the dentition. These factors should be considered in the initial stages of orthodontic treatment planning to avoid compromised treatment outcomes.
