Introduction An individual's sex, age and height are of great importance in legal medicine, especially with regard to identifying corpses. Height estimates are based on the proportionality relationship that exists between an individual's height and his various body parts. Objective To analyze the relationship between mandible measurements (length of the mandibular arch and bigonial width) and height. Materials and methods This study was conducted on the population of the Mussuca quilombo settlement, which is in the municipality of Laranjeiras, state of Sergipe, Brazil. The sample was composed of 300 individuals: 150 women and 150 men aged between 18 and 85 years old. The statistical analysis was done using the Statistical Package for the Social Scienes SPSS®, version 19.0, for Windows (SPSS Inc., Chicago, EUA) and Excel 2010 (Microsoft Corp., Redmond, WA, USA). Results The correlation coefficients were found to be low, with weak correlations between the measurements of the mandibula and height. Analysis on these values shows a very small positive correlation between height and the length of the mandibular arch among males (r = 0.177; p < 0.05) and among females (r = 0.271; p = 0.001); and between height and bigonial width among females (r = 0.169; p < 0,05). Conclusion Height may be estimated less exactly in cases in which only cephalofacial dimensions are available for legal medical examination.

ABSTRACT Introduction: The alterations in the arch form during treatment are dictated by the dimensions of the archwires. Objective: This study aimed to determine the mean arch dimensions of a sample of Pakistani subjects and to evaluate the conformity of preformed archwires with mandibular arch form. Methods: The dental records of 1,500 adult subjects were evaluated. The mandibular casts of 42 subjects (males = females = 21) with balanced facial profile, Class I occlusion, ideal overjet and overbite were included. Brackets were bonded on all teeth. Arch dimensions were evaluated at canines, first premolars, second premolars, first and second molars, with digital vernier calipers. The arch widths at the level of aforementioned teeth were evaluated on the digitized archwires, using the mean arch depths of the subjects. Results: In males, the archwires were found to be wider at canines and premolars, and significantly narrower at first (p< 0.001, 95% CI = 2.03 - 5.74) and second molars (p< 0.001, 95% CI = 2.29 - 7.73) as compared to the arch dimensions of the mandibular casts. In females, the archwires were significantly narrower at canines (p< 0.001, 95% CI = 1.4 - 3.97), and first (p= 0.02, 95% CI = 0.402 - 4.41) and second molars (p< 0.001, 95% CI = 1.76 - 6.13). Conclusion: No single commercially available archwires evaluated in the present study conformed to the arch dimensions of our subjects. Utilization of the currently available archwires may result in unwarranted modification of arch form, which may lead to unstable post-treatment teeth position.

Abstract: Mandibular arch size and form are required in order to establish proper diagnoses and orthodontic treatment plans. Mandibular dental arch is a factor affecting maximum stability of treatment outcomes. The purpose of this study was to determine means of mandibular arch size and form in Mongondow ethnic group.This research was classified into descriptive observational with cross sectional study. Sample of this research were 35 peoples aged 18-25 years at the original Mongondow ethnic group based on two generation of grandparents. Samples were taken by using purposive sampling method. The measurement of dental arch length and width were done in sagittal and transversal direction based on the Raberin’s method. Results showed that the average values of mandibular arch length in Mongondow ethnic group which categorized as depths of canines (L31), depths first molars (L61) and depths of second molars were 5.18 mm;24.26 mm; and 39.34 mm respectively. The average values of mandibular arch width which categorized as inter canines (L33), inter first molars (L66) and inter second molars (L77) were 27.38 mm, 45.60 mm and 53.59 mm respectively. The most mandibular arch form of Mongondow ethnic group was mid (51.4%) and the less of this group was pointed (5.7%).Keywords: dental arch size, dental arch form, mandibular, Mongondow ethnic groupAbstrak: Ukuran dan bentuk lengkung gigi rahang bawah sangat diperlukan dalam menentukan diagnosa dan rencana perawatan ortodontik yang tepat. Lengkung gigi rahang bawah merupakan faktor yang sangat berpengaruh dalam mempertahankan stabilitas hasil perawatan ortodonti. Tujuan penelitian ini yaitu untuk mendapatkan rerata ukuran dan bentuk lengkung gigi rahang bawah pada suku Mongondow. Jenis penelitian ini yaitu observasional deskriptif dengan desain penelitian cross sectional study. Sampel yang diperoleh sebanyak 35 orang suku Mongondow asli dari dua generasi yag berusia 18-25 tahun. Pengambilan sampel dilakukan dengan menggunakan teknik purposive sampling. Pengukuran panjang dan lebar lengkung gigi diukur dalam arah sagital dan transversal pada model studi/hasil cetakan rahang bawah dengan metode Raberin. Hasil pengukuran diperoleh rerata ukuran panjang lengkung gigi rahang bawah pada suku Mongondow yang dikategorikan sebagai kedalaman kaninus (L31), kedalaman molar pertama (L61) dan kedalaman molar kedua (L71) berturut-turut yaitu 5,18 mm; 24,26 mm; dan 39,34 mm. Rerata ukuran lebar lengkung gigi yang dikategorikan sebagai lebar interkaninus (L33), lebar intermolar pertama (L66) dan lebar intermolar kedua (L77) berturut-turut yaitu 27,38 mm; 45,60 mm dan; 53,59 mm. Bentuk lengkung gigi rahang bawah pada suku Mongondow paling banyak yaitu bentuk mid (51,4%) dan yang paling sedikit yaitu bentuk pointed (5,7%).

Dental Arch Form

This study evaluated the early changes of maxillary alveolar arches of operated unilateral cleft lip and palate patients. Dental casts were available at four age increments. Triangular flap cheiloplasty was carried out at an early age. Two-stage palatoplasty by vomer flap and soft palate closure took place later. Prior to lip repair, the alveolar arches were classified according to the relationship between greater and lesser segments. Almost a quarter had overlap of the alveolar segments with no contact between the alveolar ridges at the cleft site; some had no overlap with contact of the alveolar segments in the cleft region; almost a quarter had both overlap of the alveolar segments and contact; and almost half had no overlap of the segments and the alveolar ridges were not in contact at the cleft site. After lip repair, the arch relationships were examined and the percentage of patients in each of the four groups indicated a moulding effect of lip repair on the alveolar segments. This moulding effect caused the alveolar segments in most patients to be in contact at the cleft site. Most of these also had segment overlap. All patients were re-examined shortly after palatal repair. The trend for segment overlap and contact continued after palate surgery. However, when all patients were seen at age 4, percentages of patients in each group indicated that previous overlap of segments improved to a more desirable nonoverlapped relationship in approximately half of the patients. The other half continued to demonstrate arch collapse, in excess of what would be considered ideal ridge relationship.
