OBJECTIVE: To evaluate the aesthetic outcome by varying the duration allowed for infiltrant penetration when treating white spot lesions with resin infiltration. DESIGN: An in vitro, experimental randomised study. METHODS: Artificially created white spot lesions (WSLs) were induced on 100 extracted anterior teeth (T1). Teeth were divided into enamel and dentine groups depending on the extent of the lesion and then randomly assigned into different treatment protocol groups: penetration times of 3, 6 and 9 min...

Meta-analysis is a statistical method used in systematic reviews to provide a quantitative estimate of the effect. However, including very few studies and participants may increase the risk of spurious findings. Trial sequential analysis (TSA) has been introduced to enhance the robustness of meta-analysis. TSA is a cumulative meta-analysis method that weighs type I and II errors while estimating the effect. The application of TSA can lead to a more accurate estimation of the clinical effectiveness of the intervention...

OBJECTIVE: This systematic review aimed to compare periodontal outcomes of surgically exposed and orthodontically aligned buccally impacted maxillary canines to spontaneously erupted maxillary canines. DATA SOURCES: An unrestricted search was carried out of indexed databases (Medline, EMBASE, Web of Science and Scopus), reference lists of included studies, and grey literature published until December 2023. DATA SELECTION: Observational and experimental studies that addressed the focused question 'Do periodontal outcomes of buccally impacted maxillary canines that were surgically exposed and subsequently extruded and aligned using orthodontic alignment differ from those of spontaneously erupted maxillary canines?' were included...

OBJECTIVE: To assess and compare the validity of 2D modified Easy Box and measurement of the Beta angle on standard conventional orthopantomogram (OPG) versus 3D cone-beam computed tomography (CBCT) OPG-constructed view. DESIGN: A retrospective agreement study. METHODS: The aim of this study was to construct an Easy Box on a standard conventional OPG and to validate this novel method by comparing it with the Easy Box method on 3D CBCT. After approval from the Ethics Committee, OPG and CBCT radiographs were obtained for the study from departmental records and five private practices in the same location (Indore, India)...

The aim of this case series was to illustrate the development of late-forming supernumerary teeth (LFST) and highlight the implications for orthodontic treatment. There are limited studies relating to the aetiology, prevalence and treatment of LFST and the cases presented here demonstrate the management of LFST within a tertiary care centre. Five cases are presented, which show various presentations and chronological ages in the development of LFST. This case series emphasises the significance of maintaining a low threshold for suspecting LFST in patients where supernumerary teeth have previously been identified...

OBJECTIVE: To evaluate the difference in the oral hygiene status of participants with fixed appliances between a 'weekly WhatsApp application oral hygiene message reminders' trial group and a 'verbal instructions' control group over a follow-up duration of 12 weeks. DESIGN: Prospective, single-blind, randomised controlled trial with an allocation ratio of 1:1 over a 12-week follow-up. SETTING: Government Orthodontic Unit, Raub Dental Clinic, Raub, Pahang, Ministry of Health, Malaysia...

OBJECTIVE: To evaluate the prevalence of bullying among schoolchildren and to study the correlation between bullying and a specific type of malocclusion, self-esteem, oral health-related quality of life (OHRQoL), the need for orthodontic treatment and socioeconomic status. DESIGN: A cross-sectional study. SETTING: Low, middle and high socioeconomic-class schools in the same educational district in Cairo, Egypt. PARTICIPANTS: A total of 324 Egyptian schoolchildren aged 11-14 years...

OBJECTIVE: To evaluate the knowledge and preference of patients treated at a Dental School in Jaraguá do Sul, Brazil, about using aligners and the reasons for choosing this device as a treatment option. DESIGN: A cross-sectional study. PARTICIPANTS: A total of 82 participants aged 18-45 years recruited at a screening clinic. METHODS: A questionnaire was completed in person using a tablet with digital forms. RESULTS: Almost half of the participants (49%) knew about aligners; 40% were aged 18-24 years, and 77% were female...
