To assess the knowledge, awareness, and perception of non-dentists offering orthodontic treatment among the Malaysian young adult population.

Background: The increasing number of young adults seeking cheaper and easily accessible orthodontic treatment from unlicensed practitioners in Malaysia poses significant risks to patients. Therefore, it is essential to evaluate their motivations and awareness regarding such practices. The objective of our study was to assess the knowledge, awareness, and perceptions of non-dentists offering orthodontic treatment among the Malaysian young adult population.

Hard and soft tissue shape variation and changes in Class II division 1 malocclusion during orthodontic treatment: a geometric morphometric analysis.

Background: This study aims to determine the hard and soft tissue shape variation and its changes in Class II division 1 malocclusion before and after orthodontic treatment using Geometric Morphometric Analysis.

Methods: This retrospective study included 141 pre-treatment and near-end treatment lateral cephalometric radiographs of Class II division 1 malocclusion patients aged 16-40 years with a skeletal II pattern (ANB > 4). 32 landmarks in Cartesian coordinates were created and identified using MorphoJ software to establish a shape analysis.

A morphometric approach to morphology analysis of palatal rugae in sibling groups.

Recent advances in imaging technologies, such as intra-oral surface scanning, have rapidly generated large datasets of high-resolution three-dimensional (3D) sample reconstructions. These datasets contain a wealth of phenotypic information that can provide an understanding of morphological variation and evolution. The geometric morphometric method (GMM) with landmarks and the development of sliding and surface semilandmark techniques has greatly enhanced the quantification of shape.

Gender and age effects on dental and palatal arch dimensions among full siblings.

Purpose: This study was conducted to investigate the dental and palatal arch dimensions of male and female siblings in relation to gender and age, using three-dimensional (3D) digital casts.

Methods: This study involved 54 subjects (27 pairs) of male-female siblings aged 15 to 45 years. Dental casts were digitized and analyzed for tooth size (TS), arch width (AW), arch length (AL), arch length discrepancy (ALD), and palatal arch dimensions (PAD).

Geometric morphometric analysis of mandibular symphysis in Class III skeletal base.

This study aimed to investigate the general mandibular symphysis (MS) shape variation among Class III skeletal base, using geometric morphometric analysis. Pre-treatment lateral cephalometric radiographs of 254 patients aged 11-40 years old, with Class III skeletal base (ANB <1°) and lower incisor angle (<99°) were included. Nine-landmarks with x and y coordinates were identified on MS using TPSDig2 software, then exported into Morpho J for shape and statistical analysis.

The Heritability of Palatal Rugae Morphology Among Siblings* †.

Although there is clinical applicability of the palatal rugae as an identification tool in forensic odontology, controversy exists whether the palatal rugae patterns are stable or variable. The greater the genetic component, the higher the probability that palatal rugae patterns are stable. The aim of this study was to compare the palatal rugae morphology between full siblings and the proportion of variability due to genetic component.

study of white spot lesion: Maxilla and mandibular teeth.

Aim: The aim of the study was to evaluate the effect of resin infiltration on colour changes and surface roughness of artificial white spot lesions (WSLs) on maxillary and mandibular premolar.

Materials And Methods: Sixty (60) extracted sound Maxilla (Mx) and Mandibular (Mn) premolars were randomly divided into 2 groups (test and control). Artificial WSLs were produced on buccal surface of teeth and were immersed in artificial saliva for 8 weeks.

Human evaluation in association to the mathematical analysis of arch forms: Two-dimensional study.

Objectives: To evaluate the relationship between human evaluation of the dental-arch form, to complete a mathematical analysis via two different methods in quantifying the arch form, and to establish agreement with the fourth-order polynomial equation.

Materials And Methods: This study included 64 sets of digitised maxilla and mandible dental casts obtained from a sample of dental arch with normal occlusion. For human evaluation, a convenient sample of orthodontic practitioners ranked the photo images of dental cast from the most tapered to the less tapered (square).

Correlation and agreement of a digital and conventional method to measure arch parameters.

Objective: The aim of the present study was to determine the overall reliability and validity of arch parameters measured digitally compared to conventional measurement.

Methods: A sample of 111 plaster study models of Down syndrome (DS) patients were digitized using a blue light three-dimensional (3D) scanner. Digital and manual measurements of defined parameters were performed using Geomagic analysis software (Geomagic Studio 2014 software, 3D Systems, Rock Hill, SC, USA) on digital models and with a digital calliper (Tuten, Germany) on plaster study models.

Dental care access among individuals with Down syndrome: a Malaysian scenario.

Objective: The purpose of this cross-sectional study was to assess the legal representatives' perceptions on dental care access of individuals with Down syndrome (DS) compared to their non-DS siblings in Peninsular Malaysia.

Methods: This cross-sectional study was conducted throughout community-based rehabilitation centers (CBRC) and the Down Syndrome Organization. Legal representatives of individuals with DS within the criteria were given a structured and validated questionaire.

Malocclusion and orthodontic treatment need evaluated among subjects with Down syndrome using the Dental Aesthetic Index (DAI).

Objective: To determine the prevalence of malocclusion and need for orthodontic treatment among persons with Down Syndrome (DS).

Materials And Methods: Study participants were 113 persons with DS from the selected community-based rehabilitation center who fulfilled the inclusion and exclusion criteria. Ten occlusal characteristics of the Dental Aesthetic Index (DAI) were measured on study models to determine the degree of malocclusion.
