Development and validation of the Thai Halitosis Associated Life-Quality Test (T-HALT): an evaluation of psychometric properties.

Background: Halitosis appears to have significant impacts on quality of life, necessitating reliable assessment tools. The Halitosis Associated Life-Quality Test (HALT) has been validated in various populations, but not among Thai people. While HALT provides a valuable foundation, there is a need for a culturally adapted and expanded instrument for the Thai context.

A Comparison of Tooth Size and Arch Dimensions Among Measurements Taken Intraorally with 3D-Printed and Digital Models Obtained from Intraoral Scans.

Background: To compare measurements of tooth size and arch dimensions among those taken directly intraorally with those made on digital and 3D printed models produced by intraoral scanning.

Material And Methods: Sixty-six participants were recruited. Intraoral tooth size and arch measurements were taken intraorally with a digital caliper.

Classification of cervical vertebral maturation stages with machine learning models: leveraging datasets with high inter- and intra-observer agreement.

Objectives: This study aimed to assess the accuracy of machine learning (ML) models with feature selection technique in classifying cervical vertebral maturation stages (CVMS). Consensus-based datasets were used for models training and evaluation for their model generalization capabilities on unseen datasets.

Methods: Three clinicians independently rated CVMS on 1380 lateral cephalograms, resulting in the creation of five datasets: two consensus-based datasets (Complete Agreement and Majority Voting), and three datasets based on a single rater's evaluations.

Impacts of mandibular setback with or without maxillary advancement for class III skeletal correction on sleep-related respiratory parameters: A systematic review and meta-analysis.

A systematic review and meta-analysis was conducted to evaluate the impacts of mandibular setback with or without maxillary advancement for class III skeletal correction on respiratory parameters measured by polysomnography (PSG) and to compare these respiratory parameters between these procedures for class III skeletal correction. Six electronic databases were searched up to June 2023. Studies comparing PSG parameters before and after orthognathic surgery for skeletal class III patients were selected for further analysis.

Effects of nasoalveolar molding on nasolabial aesthetics in patients with cleft lip and palate during pre-adolescence: A systematic review and meta-analysis of retrospective studies.

This study aims to analyze long-term effects of nasoalveolar molding (NAM) as a part of cleft primary management protocols on nasolabial aesthetics for patients with non-syndromic cleft lip and palate by conducting a systematic review and meta-analysis. Six electronic databases and two journals were searched up to July 2023. Studies comparing nasolabial outcomes between NAM and non-NAM protocols were selected for further analysis.

Association between nasal septum deviation and transverse maxillary development: A retrospective cross-sectional study.

Introduction: The few studies investigating the relationship between nasal septum deviation (NSD) and maxillary development, using different assessment methods and the age of subjects, reported contradicting results.

Methods: The association between NSD and transverse maxillary parameters was analyzed using 141 preorthodontic full-skull cone-beam computed tomography scans (mean age, 27.4 ± 9.

Occlusal stimuli regulate interleukin-1 beta and FGF-2 expression in rat periodontal ligament.

While many studies reported the structural changes in the periodontal ligament (PDL) under hypofunctional conditions, the associations of cytokine growth factors are still unclear. They are known to take part in inflammation, and may affect the biological properties of hypofunctional tooth. To investigate the hypofunctional PDL and the recovery from this condition, we focused on interleukin-1 beta (IL-1beta) and basic fibroblast growth factor (FGF-2).
