OBJECTIVES Proper diagnosis and prevention of malocclusion are superior to treatment. Discrepancy between arch length and tooth size in mixed dentition period is a condition requiring timely diagnosis. Estimating the mesiodistal width of unerupted teeth according to the size of erupted ones can lead to earlier diagnosis of malocclusion. On the other hand, the best timing for serial extractions ...

This study aimed at evaluating measurements relative to the mesiodistal crown width and enamel thickness of maxillary first bicuspids. The sample consisted of 40 extracted sound bicuspids (20 right and 20 left), selected from white patients (mean age: 23.7 +/- 4.2 years), who were treated orthodontically with tooth extraction at a private clinic in São Paulo, SP, Brazil. All teeth were embedded...

the permanent successor is present, eruption of a submerged tooth may be delayed or redirected from its normal path into a malaligned position. If the permanent successor is absent, loss of dental arch space is likely, and a midline discrepancy may occur because the mesiodistal width of the primary submerged tooth is greater than that of the contralateral premolar. Also, overeruption of the opp...

background and aims. hypodontia is a common developmental abnormality of dentition. this study aimed to determine tooth width in patients affected with mild hypodontia and compare the results with a control group without tooth agenesis. materials and methods. the orthodontic records of 25 patients with congenital missing of one or two teeth (hypodontia group), and 25 subjects with full dentitio...

Clinical studies suggest that maternal smoking during pregnancy can reduce the crown size of the child's teeth. Delayed dental age compared with chronological age has also been reported in children whose parents smoke. Among the main components of tobacco smoke are nonhalogenated polycyclic aromatic hydrocarbons (PAHs), many of which are highly toxic. Humans are exposed to PAH compounds mainly ...

Proper occlusion depends on the correct width ratio between upper and lower teeth, known as Bolton's ratio. In fact, this ratio can be calculated for each pair of teeth from the central incisor to the first permanent molar. This set of ratios, known as comprehensive cumulative percentage ratios (CPRs), can be used not only to determine which tooth or teeth have a tooth width discrepancy, but ca...

The size and shape of a tooth vary between individuals different ethnic groups genders because the influence genetic factors. information regarding anatomical factors using maxillary anterior teeth is very scanty. Thus to give more clarity, study was planned assess correlation head circumference tooth-mesiodistal width among children origins.The carried out on 210 aged 7 12 years in schools at ...

OBJECTIVE Provide reference basis for the clinical implant restoration to select implant diameter through measuring each data of 7 teeth in the dental neck of bilateral upper and lower jaws of the young volunteers with normal dentition. METHODS Select 30 healthy young volunteers with complete dentition but no malocclusion, take cone beam CT (CBCT), measure the mesiodistal and buccolingual dis...
