UNLABELLED Regards and Tribute: Late Dr Narender Hasija was a mentor and visionary in the light of knowledge and experience. We pay our regards with deepest gratitude to the departed soul to rest in peace. Bolton's ratios help in estimating overbite, overjet relationships, the effects of contemplated extractions on posterior occlusion, incisor relationships and identification of occlusal misfit...

Study background: Bolton Index is one of the most commonly used analysis in order to evaluate tooth-size discrepancy. Even if this measure could represent an important tool in clinical practice, many Authors questioned its widespread applicability. The aim of this study was to compare the anterior and total tooth width ratios of an orthodontic population with the Bolton standards and analyse di...

This retrospective investigation was designed to compare tooth size discrepancies among subjects with different skeletal malocclusions in an orthodontic population. The study employed the pre-treatment models of 200 patients (100 males, 100 females, aged from 14 to 20 years) selected from the records of the Orthodontic Department, Shiraz Dental School. The subjects were from four malocclusion g...

A. Error. This word is used correctly with two different meanings: 1. To denote the difference between a measured value and the "true" value. Except in a few trivial cases, the "true" value is unknown and the magnitude of the error is hypothetical. 2. When a number such as (±.087) is given or implied, "error" refers to the estimated uncertainty in an experiment and is expressed in terms of such...

This study aimed to assess and compare the overall and anterior ratios of tooth size discrepancies in all Angle malocclusion groups. The following null hypothesis (H0) was tested: no difference between tooth size discrepancies (overall and anterior) would be observed among Angle malocclusion groups. The sample comprised of 711 pre-orthodontic treatment study casts of Brazilian patients with a m...

Dental professionals have long been guided by mathematical principles when interpreting aesthetic and tooth proportions for their patients. While many acknowledge that such principles are merely launch points for a smile design or reconstructive procedure, their existence appears to indicate practitioners' desire for predictable, objective, and reproducible means of achieving success in aesthet...
