OBJECTIVE This study evaluated dental arch dimensional changes of Brazilian children. MATERIAL AND METHODS Dental casts were taken from 66 children (29 males; 37 females) with normal occlusion selected among 1,687 students from public and private schools aged 9, 10, 11 and 12 years, according to the following criteria: Class I canine and molar relationships; well-aligned upper and lower denta...

OBJECTIVE To determine the most common maxillary and mandibular arch form and size in primary dentition stage. MATERIAL AND METHODS Four hundred thirty five preschool children were included in this study with an age range of 3.5-5.5 years old. Dental casts were digitized and landmarks for the measurements were identified and marked on each model. Ten points were determined on the dental arch....

Introduction: The mandibular arch form is considered one of the main references among the diagnostic tools because the maintenance of this arch form and dimension is an important factor for stability of orthodontic treatment. Objectives: to evaluate the changes in mandibular intercanine and intermolar widths during orthodontic treatment and 3 years of post treatment, in which the WALA ridge was...

The purpose of this study was to provide information about arch shape variations among South Pacific populations. The application of Fourier transforms, Y(phi i) = ao/2 + sigma (aicos phi i + bisin phi i) was used to separate two components of variation; size and shape. Dental arch size can be described by one coefficient (ao), while the shape can be summarized by the first three harmonics (amp...

OBJECTIVE To describe the distribution of edentulism and estimate the prevalence of functional dentition and shortened dental arch among elderly population. METHODS A population-based epidemiological study was carried out with a sample of 5,349 respondents aged 65 to 74 years obtained from the 2002 and 2003 Brazilian Ministry of Health/Division of Oral Health survey database. The following va...

Introduction: A study model is a precise three dimensional replica of patient’s dentition and plays an important role in treatment planning. Many digital multi-media applications have become available to the clinician and his or her staff to facilitate standard procedures in practice and management. The aim of this study is to evaluate reliability and validity of dental measurement made on dig...

The salivary glands may be classified from three aspects: size: large and small (or accessory) salivary glands; the position of the efferent outlet: outside or within the dental arch; the character of the secretion produced: serous or mucinous. When the classification is made on the above basis, the large salivary glands are as follows: the parotid gland, which is situated outside the dental ar...

Introduction With the advancement in imaging technology, 3D dental computed tomography plays a very significant role in orthodontic treatment and diagnosis. Aim To evaluate dental crowding in relation to the mesiodistal crown widths and arch dimensions and also to determine the differences of dental crowding among males and females, in Southern Indian population. Materials and Methods A tot...
