Students' perception on flipped classroom in contrast to live demonstration for teaching orthodontic wire-bending skills: A focus group study.

Objective: This study aimed to explore students' perceptions of flipped classroom (FC) compared to live demonstration (LD) in transferring skills of fabricating orthodontic wire components for orthodontic removable appliances.

Methods: Forty third-year undergraduate dental students were randomly assigned to two groups: FC (n = 20) and LD (n = 20). Students in group FC attended FC, while students in group LD attended LD.

Students' perception on flipped classroom with formative assessment: A focus group study.

Objective: To explore students' perception on the implementation of flipped classroom (FC) combined with formative assessment during the undergraduate teaching of orthodontic wire-bending skills.

Methods: Third-year undergraduate dental students were taught wire-bending skills via FC teaching method using a series of pre-recorded online video demonstrations. As part of the formative assessment, the students were given the results and assessment rubrics of their prior wire-bending assessment before every subsequent session.

A multicenter study on the prevalence of adults and children seeking orthodontic treatment at high risk of obstructive sleep apnea.

Objective: To investigate the prevalence of adults and children seeking orthodontic treatment at high risk of obstructive sleep apnea (OSA) and pediatric OSA (POSA) and its association with demographic variables.

Methods: One hundred-eleven adults and 105 children were consecutively recruited from three centers. The Epworth Sleepiness Scale (ESS) and ESS for Children and Adolescents were used for Risk stratifications for OSA and POSA.

The effect of live demonstration and flipped classroom with continuous formative assessment on dental students' orthodontic wire-bending performance.

Background: Wire-bending skills is commonly taught through live demonstrations (LD) though flipped classroom (FC) method has gained popularity. Continuous formative assessment promotes personalised learning via closely monitored progress, with the identification of students' strengths and weaknesses. This study aims to evaluate the effects of LD and FC teaching methods, supplemented with continuous formative assessment, on dental students' learning of wire-bending skills for six types of removable orthodontic appliance components.

The global distribution of permanent canine hypodontia: A systematic review.

Objective: To systematically review studies on canine agenesis prevalence in different populations and continents, based on the jaw, sex, location, and associated dental anomalies.

Methods: Electronic and hand searches of English literature in PubMed, Web of Science, Scopus, OpenGrey, and Science Direct were conducted, and the authors were contacted when necessary. Observational studies (population-based, hospital/clinic-based, and cross-sectional) were included.

Distribution of mandibular trabeculae bone volume fraction in relation to different MOP intervals for accelerating orthodontic tooth movement.

Objectives: To investigate the effect of micro-osteoperforation (MOP) on the horizontal and vertical distribution of mandibular trabeculae bone volume fraction in relation to different MOP intervals during canine retraction.

Materials And Methods: This single-center, single-blinded, prospective randomized split-mouth clinical trial included 30 healthy participants aged 18 years and older, randomized into three groups of different MOP intervals (4, 8, and 12-weekly). Cone beam computed tomography images were taken to assess the bone volume fraction (bone volume over total volume or BV/TV).

Osseous evidence behind micro-osteoperforation technique in accelerating orthodontic tooth movement: A 3-month study.

Introduction: The study aimed to investigate the effects of micro-osteoperforations (MOPs) on the mandibular bone volume/tissue volume (BV/TV) ratio changes and the rate of orthodontic tooth movement using cone-beam computed tomography images. Another objective was to evaluate the effects of MOP frequency intervals (4 weeks, 8 weeks, and 12 weeks) on the BV/TV ratio and rate of tooth movement.

Methods: In 24 participants, 140-200 g of force was applied for mandibular canine retraction.

Coordination of Nanoconjugation with an Antigen/Antibody for Efficient Detection of Gynecological Tumors.

Cervical, ovarian, and endometrial cancers are common in the female reproductive system. Cervical cancer starts from the cervix, while ovarian cancer develops when abnormal cells grow in the ovary. Endometrial or uterine cancer starts from the lining of the womb in the endometrium.

The effect of micro-osteoperforations on the rate of orthodontic tooth movement: A systematic review and meta-analysis.

Introduction: Minimally invasive micro-osteoperforations (MOPs) look promising for a routine acceleration of orthodontic tooth movement (OTM). The objective of this research was to systematically evaluate evidence regarding the effects of MOPs on the OTM rate, treatment duration, and associated complications.

Methods: Electronic database and hand search of English literature in PubMed, Cochrane Central Register of Controlled Trials, Embase, Web of Science, and clinical trial.

Mini-implant supported canine retraction with micro-osteoperforation: A split-mouth randomized clinical trial.

Objectives: To investigate, using a split-mouth randomized clinical design, the effect of micro-osteoperforation (MOP) on mini-implant supported canine retraction using fixed appliances.

Materials And Methods: Thirty subjects (seven males and 23 females) with a mean age of 22.2 (3.

Mandibular arch orthodontic treatment stability using passive self-ligating and conventional systems in adults: A randomized controlled trial.

Objective: This randomized controlled trial aimed to compare the stability of mandibular arch orthodontic treatment outcomes between passive self-ligating and conventional systems during 6 months of retention.

Methods: Fortyseven orthodontic patients with mild to moderate crowding malocclusions not requiring extraction were recruited based on inclusion criteria. Patients (mean age 21.

Anthropometric Study of Three-Dimensional Facial Morphology in Malay Adults.

Objectives: To establish the three-dimensional (3D) facial soft tissue morphology of adult Malaysian subjects of the Malay ethnic group; and to determine the morphological differences between the genders, using a non-invasive stereo-photogrammetry 3D camera.

Material And Methods: One hundred and nine subjects participated in this research, 54 Malay men and 55 Malay women, aged 20-30 years old with healthy BMI and with no adverse skeletal deviation. Twenty-three facial landmarks were identified on 3D facial images captured using a VECTRA M5-360 Head System (Canfield Scientific Inc, USA).

The oral health of people with chronic schizophrenia: A neglected public health burden.

Objective: People with chronic schizophrenia have high rates of physical ill-health such as heart disease. However, there has been less attention to the issue of poor oral health including dental caries (tooth decay) and periodontal (gum) disease, although both have consequences for quality of life and systemic physical health. We therefore measured tooth decay and gum disease in Malaysians with schizophrenia.

The safety zone for mini-implant maxillary anchorage in Mongoloids.

Aim: This study aimed to establish a safety zone for the placement of mini-implants in the buccal surface between the second maxillary premolar (PM2) and first maxillary molar (M1) of Mongoloids.

Methods: Thirty-two digital orthopantomograms of Mongoloids were selected and the interdental distance between the second premolar and first molar at 2, 5, 8 and 11 mm from the cemento-enamel junction (CEJ) was measured. The distance between the PM2 and M1 root apices and from the apices to the maxillary sinus was also determined.

Condylar growth and mandibular positioning with stepwise vs maximum advancement.

Introduction: The aim of this study was to compare the effects of several Class II malocclusion treatments on condylar growth and positioning of the mandible.

Methods: The material comprised series of lateral cephalograms obtained at the start, after about 6 months, and after about 12 months of treatment from 3 groups of consecutively treated patients who used a headgear-activator with stepwise mandibular advancement (HGA-S), a headgear-activator with maximum jumping of the mandible (HGA-M), and a headgear-Herbst appliance with stepwise advancement (HGH-S), respectively. Six-month growth data from matched controls were used to calculate the net treatment effects.
