OBJECTIVE To compare the vertical facial and dental arch dimensional changes occurring with extraction and nonextraction orthodontic treatments. STUDY DESIGN Cross-sectional comparative study. PLACE AND DURATION OF STUDY The Aga Khan University Hospital, Karachi during the period 2003 to 2005. METHODOLOGY Data were collected using records of patients who visited the study setting during t...

BACKGROUND The aim of this retrospective study was to identify which dental and/or cephalometric variables were predictors of long-term maxillary dental arch stability in patients treated with a transpalatal arch (TPA) during the mixed dentition phase followed by full fixed appliances in the permanent dentition. METHODS Thirty-six patients, treated with TPA followed up by full fixed appliance...

The purpose of this study was to compare the dentoalveolar changes produced when using two different intraoperative surgical procedures for maxillary distraction osteogenesis. Eight patients were assigned into two groups according to the surgical procedure: down-fracture (DF, n = 6) vs non-down-fracture (NDF, n = 2). Lateral cephalograms and 3-D models before and after maxillary distraction wer...

The stature or height of an individual is useful for assisting in forensic identifications. Teeth can act as a valuable tool for stature estimation when only the skull is available. Carrea's index estimates the stature of a person from the dimensions of lower anterior teeth. The aim of this study was to assess the reliability of the Carrea's index in an Indian population. Data was collected fro...

Detailed oro-maxillofacial studies using dental cast, pantomogram and cephalogram were performed in 43 patients with GH deficiency aged 7-17 years and compared statistically to the results from 62 short children with normal GH secretion. The dental age was retarded as compared to the chronological age in patients with GH deficiency by a mean of 2.0 +/- 1.3 years. This value did not differ stati...

Cleft malformations belong to the most common facial congenital defects. This study compares the impact of early and late reconstruction of complete unilateral cleft lip and palate on the growth and development of the posterior part of dentoalveolar arch. Maxillary dental casts of 35 infants were used for analyses. They were divided into 2 groups according to the timing of the lip reconstructio...

As noted in a recent article, 1 interest in rapid palatal expansion (RPE), which has traditionally been used to resolve crossbites, has increased markedly in the past 2 decades. Orthodontists using this procedure might be seeking to gain arch perimeter to avoid extractions. This treatment, which is most often started in the mixed dentition, raises some interesting questions. One question is thi...
