BACKGROUND: Lateral cephalometric analysis (LCA) is the reference standard for identifying common skeletal relationships in orthodontics, such as Cl II and hyperdivergent skeletal discrepancies, but it entails radiation exposure. Therefore, photographic soft-tissue profile analysis (PSPA) could be a useful alternative for these diagnoses, particularly for paediatric patients. This study aims to estimate the accuracy of PSPA for determining common skeletal discrepancies in children. METHODS: Cephalometric radiographs and profile photographs of a consecutive series of 100 children (8...

OBJECTIVES: Positive effects of irisin on osteogenic differentiation of periodontal ligament (PDL) cells have been identified previously, this study aims to examine its effect on orthodontic tooth movement (OTM) in vivo. MATERIALS AND METHODS: The maxillary right first molars of male Wistar rats (n = 21) were moved mesially for 14 days, with submucosal injection of two dosages of irisin (0.1 or 1 μg) or phosphate-buffered saline (control) every third day. OTM was recorded by feeler gauge and micro-computed tomography (μCT)...

BACKGROUND: Orthodontic treatment is a long process that requires patient cooperation. Risks of side effects such as caries formation, periodontal problems, and root resorption increases as well as problems in patient cooperation arises with longer treatments. Several different techniques were developed that may shorten the treatment time. OBJECTIVE: The aim of this study was to evaluate the effectiveness of micro-osteoperforations (MOPs) performed during the alignment stage...

BACKGROUND: Maxillary bonded and removable retainers maintain teeth in correct positions following orthodontic treatment. There is insufficient evidence regarding the capacity of the retention methods to stabilize the maxillary teeth both during and after retention. OBJECTIVE: To evaluate retention capacity and 1-year post-retention changes in the irregularity of maxillary anterior teeth and single anterior tooth contact point discrepancy (CPD) of two bonded and one removable retention method...

BACKGROUND: Non-nutritive sucking habits likely may cause occlusal changes such as anterior open bite (AOB) if they persist over extended time. OBJECTIVES: To assess if there is self-correction of AOB after cessation of non-nutritive sucking habits in children older than 4 years old, through a systematic review. SEARCH METHODS: Data sources included PubMed, Scopus, Web of Science and Latin American and Caribbean Health Sciences (LILACS) databases, gray literature as Google Scholar, the database System for Information on Gray Literature in Europe (OpenGrey) and ProQuest Dissertations and Theses Database, also hand searches of the included studies references...

OBJECTIVE: Few studies within orthodontics present both economic and clinical findings. Missing maxillary lateral incisors is a frequently occurring anomaly. The treatment alternatives most used are orthodontic space closure and prosthetic replacement of the missing tooth. Our aim is to compare the total societal costs of orthodontic space closure (SC) and implant therapy (IT) in patients missing maxillary lateral incisors. METHODS: Records of 32 patients treated with SC (n = 18) or IT (n = 14) due to missing maxillary lateral incisors were retrieved from the archives...

BACKGROUND: 3D facial landmarking is becoming a fundamental part of clinical and biological applications. Manual landmarking is time consuming and prone to cumulative errors, so attempts have been made to automate 3D facial landmarking. However, data in the literature are sparse. OBJECTIVES: The objectives of this study are to investigate current evidence for the accuracy and reliability of various 3D facial automated landmarking methods used in medical and biological studies and evaluate their performance against the manual annotation method...

BACKGROUND: Early loss of second primary molars may lead to different malocclusions, mainly caused by the mesial migration of the first permanent molar. To prevent space loss in the dental arch, different types of space maintainers (SM) are used. OBJECTIVES: The main objective of this systematic review is to examine the evidence in the literature regarding the effect of SM, including the clinical effect, risk of developing caries and periodontal disease, patient satisfaction, and cost-effectiveness after the premature loss of the second primary molar in children...

BACKGROUND: Malocclusions in adolescents might have a negative impact on oral health-related quality of life (OHRQoL). Potential confounding variables (confounders) such as age, gender, caries, and socioeconomic status may skew the real relationship between malocclusions and OHRQoL. OBJECTIVES: To analyse the effect of malocclusions in adolescents on OHRQoL, when controlled for potential confounders. SEARCH METHODS: Five databases (PubMed, Cochrane Library, Cinahl, Scopus, and Web of Science) were searched up to 15 June 2022...

BACKGROUND/OBJECTIVES: Hypoxia during orthodontic tooth movement (OTM) induces reactive oxygen species (ROS) production in periodontal tissues. Superoxide dismutase 3 (SOD3) is an anti-inflammatory enzyme that protects cells from ROS. This study investigated the expression and function of SOD3 during rat OTM and in hypoxia-exposed rat periodontal ligament (PDL) cells. MATERIALS/METHODS: OTM of right maxillary first molars were performed in 8-week-old male Sprague-Dawley rats using closed-coil spring for 1 and 14 days (n = 6 per group)...
