OBJECTIVE To compare the accuracy and reproducibility of tooth measurements using newly developed software that gives 2-dimensional scanned images of dental setups with direct measurements using digital calipers. METHODS This experimental study was performed at the Dental Laboratories of the Faculty of Dentistry, University of Jordan, Amman, Jordan from September 2010 to December 2010. Ten se...
Statement of Problem: In some cases, a difference in size between the right and left teeth, during band selection for first molars, is observed. Purpose: The aim of this study was to measure the mesiodistal width and to compare the teeth on left and right sides of jaws in individuals with normal occlusion, according to the sex. Materials and Methods: In this cross-sectional study, sixty student...
This paper details a method for age determination of adults from single rooted teeth. The sample consisted of 100 Italian white Caucasian patients (46 men, 54 women) aged between 18 and 72 years. The single rooted maxillary right canine was utilized in this preliminary study. Pulp/root ration, tooth length, pulp/tooth length ratio, pulp/tooth area and pulp/root width ratios at three different l...

The neonatal line is a histologic landmark in primary tooth enamel corresponding to the event of birth. The average width of the neonatal line (NNL) in primary tooth enamel of 147 children was measured. In children with normal birth histories the width of the NNL was found to be 11.9 +/- 4.8 microns. It was wider (18.6 +/- 5.7 microns) in children born by difficult operative delivery and thinne...
Background and purpose: In tooth selection for dentures, the size of the tooth is really important. To estimate the size, a group of landmarks of the face have been investigated. This study evaluated the relationship between the length and width of maxillary central incisors and measurable indices of the face in patients with complete denture. Materials and methods: A descriptive-analytic cro...
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...
The purpose of this study were to compare the emergence profiles of crowns with their contralateral tooth, in vitro, and to determine if there is any association between the design of tooth preparations and the resultant emergence profile. 50 working models used for single crown construction were examined. Measurements of the faciolingual width of the crowns and contralateral teeth were taken u...
