“…Despite efforts in the Arab world during the last decades to make health systems more equitable[1415161718] access to dental healthcare is still far from adequate, especially in poor communities. In Yemeni population, there is no previous study carried out on the mandibular arch dimensions.…”

Objective:To assess the relationship between mandibular arch length and widths in a sample of Yemeni subjects aged (18-25) years.Materials and Methods:The investigation involved clinical examination of (765) adults; only 214 (101 females, 113 males) out of the total sample were selected to fulfill the criteria for the study sample (normal dento-skeletal relationship). Study models were constructed and evaluated to measure mandibular arch dimensions. The Spearman's correlation coefficient (r) was calculated between the measurements of arch widths and lengths.Results:Overall, the male group demonstrated greater transverse and sagittal mandibular dimensions; However, this was only statistically significant for measurements of inter-first and second molar distances and anterior arch length (P < 0.05). Relatively stronger linear relationships were observed between the inter-canine distance and mandibular arch lengths (P < 0.05, Spearman's r ranged between 0.17 to 0.50).Conclusion:Among studied mandibular dimensions in subjects with normal dento-skeletal relationship, only the inter-canine distance demonstrated a week to moderate linear relationship with the mandibular arch lengths.

“…It is evident that there is a range of variation, either in structure, shape, size configuration or other distinct contrasting characteristics (Hardlicka, 1907;Pittard, 1926). A number of anthropologists have related maxillary arch development to different dietary, environmental and physical factors for various populations (Sawiris, 1977;Mack, 1981;Gridly & Daas, 1985;Sarhan & Diwan, 1987;Younes, Al Shammery & El Angbawi, 1988;Diwan & Elahi, 1990;Merz et al, 1991).…”

The present study constitutes an attempt to compare normal traits for palatal height and width at different stages of dentition development of two ethnic groups of the Middle East. The observations were obtained from 346 randomly selected normal subjects, 188 Saudis and 158 Egyptians. The stone models were divided into three categories in both groups--primary, mixed and permanent dentitions. Palatal index values were calculated at two levels. Vernier calipers were used to measure the palatal width. Palatal depth was measured by profile Gauge by Vitrex. The results of this study demonstrate no significant difference between ethnic groups at levels 1 and 2 in relation to the palatal height, width and index. For both groups, palatal index increased significantly from the primary to mixed and permanent dentition at level 1. At level 2, palatal index and height showed decreases in measurement in the mixed dentition compared with the primary and the permanent dentitions. Subjective assessment of the palatal height correlated with palatal index. The casts were then labelled so that the shallow group had the smallest palatal index followed by the normal and the deep group had the largest palatal index. The results contribute to the information available on the development of palatal shape within two Middle Eastern populations. Knowledge of the normal range in shape can act as a baseline for studies of certain oral developmental abnormalities.

“…In another study significant differences between the arch width measurements were found to exist between several classes of subjects based on race and sex [11]. The results of one research showed wider PAW for the Egyptians than for the Filipinos, who also showed wider AAW than the Saudi Arabians [12].…”

A cross-sectional study was conducted to compare maxillary arch and head measurements between ethnic Malays and Chinese. Mean ages were 23.5 years (Malay) and 21.1 years (Chinese), and both groups were brachycephalic with the cephalic index 86.4 for Malay and 85.9 for Chinese which is not significantly different between them. Means of anterior arch width (AAW), posterior-arch-width (PAW) and arch-length were significantly different between two groups. AAW and PAW were significantly different from their corresponding indices for Malays but not for Chinese. The Pont's and Korkhaus' Indices could not be applied to the Malays but moderately to the Chinese.
