Tooth-size discrepancy (TSD), i.e. the disproportion between the size of the maxillary teeth and that of the mandibular teeth, impacts the quality of esthetic and occlusal results in orthodontic treatment. Various studies have shown that, in anterior TSDs, the deficit is most often maxillary and the small size of the upper lateral incisor is incriminated. The present study was performed on a sample of 30 moulds from Moroccan patients displaying an anterior TSD. The differences in the sizes of the upper and lower lateral incisors were compared with a control sample with normal occlusion. The aim of the study was to check the validity of similarity of size between the upper and the lower lateral incisors as a clinical sign of possible anterior TSD. Our results confirmed the efficacy of this rapidly detectable clinical sign in the diagnosis of anterior TSDs.

Comparison of dentoalveolar protrusion values in Moroccans and other populations.

Eur J Orthod 2010 Aug 16;32(4):430-4. Epub 2009 Dec 16.

Summary: The aim of this retrospective study was to evaluate bimaxillary protrusion among Moroccans and to compare the Moroccan population with other Arabic, Caucasian, and Mediterranean populations. Cephalometric radiographs of 102 Moroccan adult university students (73 females and 29 males, mean age: 21 years 6 months +/- 1 year 6 months) with a normal occlusion were traced. Fifteen measurements concerning the upper and lower incisors, upper and lower lips, and the Frankfort to mandibular plane angle were assessed. Statistical analysis of the data was undertaken using independent t-tests. Eight angular and six linear measurements were statistically significantly different compared with Caucasian cephalometric norms (P < 0.001). Significant differences were observed compared with other adult Arabic populations (Palestinians and Saudis) and with Turkish Anatolian adults. Relative to Caucasian cephalometric norms, Moroccans showed bimaxillary protrusion and, therefore, these norms cannot be applied to Moroccan faces. In general, there was a great similarity in incisor position between the Moroccan and Saudi populations.
