Abstract Clear aligner therapy (CAT) has gained popularity due to its aesthetic benefits, especially among adults. However, with ongoing advancements in appliance materials, concerns about resin allergies have emerged because of the extended contact between plastics and oral tissues. This case series highlights important clinical features this rare increasingly recognised issue. Diagnosing proved challenging variability presentation test results. All cases were females aged 23 28 years no...

Artificial WSLs produced buccal teeth immersed in saliva for 8 weeks. Colour components (L∗, a∗, b∗) (Sa∗) assessed 40 using difference meter RD-100 Alicona® Infinite Focus profilometer respectively....

The introduction of auxiliaries such as composite attachment has improved the force delivery clear aligner (CA) therapy. However, placement may give rise to a flash, defined excess resin around which affect CA delivery. This in vitro study aims determine differences generated by presence or absence flash CA.

The objective of this study was to assess the accuracy Chat Generative Pre-trained Transformer 4.0 (ChatGPT-4; OpenAI, San Francisco, CA ) compared Statistical Product and Service Solutions (SPSS; IBM SPSS Statistics for Windows, Armonk, NY) in performing statistical analyses commonly used medical dental research.

Objective. The purpose of this cross-sectional study was to assess the legal representatives' perceptions on dental care access individuals with Down syndrome (DS) compared their non-DS siblings in Peninsular Malaysia. Methods: This conducted throughout community-based rehabilitation centers (CBRC) and Syndrome Organization. Legal representatives DS within criteria were given a structured validated questionaire. Result. demonstrated that (76.9%) significantly utilized more health services...

Abstract 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 contain a wealth phenotypic information that can provide an understanding morphological variation and evolution. The geometric morphometric method (GMM) with landmarks the development sliding semilandmark techniques has greatly enhanced quantification shape. This study aimed to determine whether...

Abstract Although there is clinical applicability of the palatal rugae as an identification tool in forensic odontology, controversy exists whether patterns are stable or variable. The greater genetic component, higher probability that stable. aim this study was to compare morphology between full siblings and proportion variability due component. This cross‐sectional conducted on digital models 162 aged 15–30 years old. were assessed with Thomas Kotze (1983) classification using Geomagic...

ABSTRACT Objectives To compare the clinical effectiveness of Hawley retainers (HRs) and modified vacuum-formed (mVFRs) with palatal coverage in maintaining transverse expansion during a 12-month retention period. Materials Methods Data were collected from postorthodontic treatment patients who met inclusion criteria. A total 35 randomly allocated using centralized randomization technique into either mVFR (n = 18) or HR group 17). The outcome assessor data analyst blinded to method. Dental...

Information and communication technology (ICT) is an increasingly important tool in dental education practice. This may benefit the students' personal professional development. The aim of this study was to investigate attitudes perception towards ICT resources skill among clinical group students Universiti Kebangsaan Malaysia. A selfadministered questionnaire developed pretested. reliability with Cronbach's coefficient alpha 0.761. With responded rate 96.1%, revealed that majority reported...

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 base (ANB <1 o ) and lower incisor angle (<99 were included.Nine-landmarks x y coordinates identified on MS TPSDig2 software, then exported into Morpho J for statistical analysis.Principal component analysis showed that three main dimensions a total...

To evaluate the prevalence and significance of malocclusion traits orthodontic treatment needs Down syndrome (DS) subjects with matched non-syndromic (NS) controls.This cross-sectional study involved 222 (50% DS, 50% NS) who were by gender age. The casts digitized into three-dimensional images. These images used alongside ten occlusal characteristics Dental Aesthetic Index (DAI) to determine severity need for treatment.There 58 (52.3%) females 53 (47.7%) males a mean age 18.4 ± 8.4 years in...
