A survey on orthodontic services provided by general dental practitioners.

The aim of this survey-based study was to recognize professional determinants that account for variations in the level of orthodontic services provided and which distinguish providers and nonproviders of orthodontic services. Multiple regression analysis revealed that four practitioner characteristics explained 43% of the variance in the number of orthodontic patients treated. Dentists who treated more orthodontic patients (1) treated more general practice patients, (2) frequently used multiple sources to keep up to date in orthodontics, (3) perceived their patient base to contain more children, and (4) were likely to have attended an orthodontic course.

Correlation of soft palate morphology to growth pattern: A retrospective cephalometric study.

Aim: The aim of the present study was to evaluate the radiographic length of velum (LV), width of velum (WV), velum angle (AV), depth of pharynx (PD), Need's ratio (NR), inclination angle (AI) in different morphological types of soft palate according to growth patterns in skeletal class I individuals.

Methodology: 80 pretreatment lateral cephalograms of patients with skeletal class I malocclusion (ANB 2--4°) were divided on basis of six types of soft palate and further into three subgroups according to growth pattern and evaluation of LV, WV, angle with the palatal plane, and NR was done. Kruskal--Wallis test was used for the comparison between the groups.
