The prevalence of specific dental anomalies in a group of Saudi cleft lip and palate patients.

Objective: The aims of this study were to investigate the prevalence and distribution of dental anomalies in a group of Saudi subjects with cleft lip and palate (CLP), to examine potential sex-based associations of these anomalies, and to compare dental anomalies in Saudi subjects with CLP with published data from other population groups.

Design: This retrospective study involved the examination of pre-treatment records obtained from three CLP centers in Riyadh, Saudi Arabia, in February and March 2010. The pre-treatment records of 184 subjects with cleft lip and palate were identified and included in this study.

The applicability of a non-anatomical soft and hard tissue centroid line (S&H centroid) in cephalometrics.

The applicability of a newly introduced non-anatomical soft and hard tissue cephalometric centroid line (S&H centroid) was investigated. The "S&H centroid" line established from 12″ × 14″ lateral cephalometric radiographs of 57 selected adults was used as a base to create a new cephalometric reference line "Centroid-Nasion". The reliability and the use of the newly created "Centroid-Nasion" as a reference line was tested against the conventional "Sella-Nasion" cephalometric reference line to evaluate the sagittal and vertical maxillary and mandibular relationship.

The distribution and classification of clefts in patients attending a cleft lip and palate clinic in Riyadh, Saudi Arabia.

Objective: To evaluate and discuss the etiology, distribution, and classification of cleft lip and palate (CLP) patients in one of the most active CLP clinics in Riyadh, Saudi Arabia.

Methods: The records of all 171 CLP patients attending the CLP clinic at the College of Dentistry, King Saud University in Riyadh, Saudi Arabia, were collected in November and December 2006. Variables such as etiology, age, gender, type of cleft, and location of cleft were statistically analyzed.

The effect of different lower third molar conditions on the re-crowding of lower anterior teeth in the absence of tight interproximal contacts one-year post orthodontic treatment: a pilot study.

The role of lower third molars in lower incisor crowding is a debatable topic. Some believe the presence or eruption of lower third molars is associated with the crowding of mandibular incisors, others negate such association. Thirty-two newly debonded orthodontic patients, with ages ranging from 14-19 years, were randomly selected.

Orthodontic treatment planning: do orthodontists treat to cephalometric norms?

Cephalometric norms are important to orthodontists in their diagnosis, treatment, and evaluation of orthodontic treatment outcomes. The purpose of the present study is to establish if orthodontists treat and finish their cases to the cephalometric means or norms. Pre- and post-cephalometric radiographs and dental casts of 35 orthodontically treated cases were analyzed.
