INTRODUCTION The early orthodontic treatment allows correction of skeletal discrepancies by growth control, and the elimination of deleterious habits, which are risk factors for the development of malocclusions, favoring for the correction of tooth positioning later in a second treatment stage. During development of teeth and occlusion, the mandibular second molars commonly erupt in the oral ca...

INTRODUCTION Adequate tooth-size ratios are required to ensure the satisfactory outcome of orthodontic treatment. Consequently, various methods of measuring tooth-size ratios have been developed being the Bolton ratio the most commonly accepted, known and used one. This ratio depending directly on mesiodistal tooth size has been associated with different ethnic backgrounds. Some authors suggest...

Missing tooth in the anterior region of maxilla lies aesthetic zone and create quite noticeable discrepancies. With a paradigmshift patient expectations towards functional as well aesthetically appealing replacements for edentulism, implant basedoral rehabilitation has emerged sole winner fulfilling all aspects needs. Interdisciplinary team treatment planning is aparamount approach achieving op...

background and aims. tooth loss may lead to mastication disability, which in turn has important impact on individual’s quality of life. social and psychological factors have been shown to be associated with tooth loss. this study aimed to investigate the social determinants and prevalence of tooth loss, and presence of functional dentition among female heads of household under support of welfar...

Background: The use of a bone graft in regeneration is challenging. Tooth material has been used as alternative due to its similar composition organic and inorganic materials close the bone. Recently, nanotechnology improve quality. osteoconduction rate defect area represents Purpose: This study aimed compare number osteoblasts using nano-tooth grafts micro-tooth Wistar rats. Methods: rats were...

PURPOSE The aim of this study was to evaluate the mesiodistal primary tooth size diameter and posterior sagittal tooth-size ratio in an African American population and compare to existing African American and European American norms. METHODS A sample of 1,124 African American children, 564 males and 560 females, was used to record crown size diameters employing indirect (cast) and direct (int...

  In this study two groups of dental study models were selected to evaluate the relationship between the tooth size, arch dimensions , and dental crowding. The first group consisting of 56 pairs of dental study models (28 males and 28 females) with normal occlusion ( without dental crowding) ranging in  age from 16 to 20 years, were selected among 4445 students from Kerman by multi stage rando...

Second molar length and body weight are used to test the correlation between tooth size and body size in living Hominoidea. These variates are highly correlated (r= 0.942, p less than 0.001), indicating that tooth size can be used in dentally unspecialized fossil hominoids as one method of predicting the average body weight of species. Based on tooth size, the average body weight of Aegyptopith...

Exploration of the relationship between tooth dimensions, body size, and age is important in paleontology, forensic odontology and aesthetic dentistry. It is reasonable to speculate that tooth length is associated with stature since teeth contribute to facial height. This study aimed to determine whether there was an association between tooth length and stature and age in a sample of Sri Lankan...
