AI Article Synopsis
- This study compared clear aligners (CA) with removable inclined planes (RIP) for treating anterior crossbite in children aged 8 to 12, using 3D digital models to assess treatment outcomes.
- Twenty-four patients were randomly divided into two groups and evaluated on various dental metrics before and after 4 months of treatment, focusing on the movement of maxillary incisors.
- Results indicated that while both methods were effective, the clear aligner group showed greater improvements in maxillary incisor movement, intermolar width, and arch perimeter compared to the RIP group.
Article Abstract
Background: This study aimed to compare the efficacy of clear aligners and removable inclined planes (RIP) in management of anterior crossbite in late mixed dentition patients using a 3D digital model.
Materials And Methods: Twenty-four patients with functional anterior crossbite, aged 8 to 12 years old, were randomly assigned to two parallel groups: the clear aligner (CA) group with a mean age of 10.74 ± 1.1 years, treated with clear aligner, and the RIP group with a mean age of 10.54 ± 1.06 years. Digital models were obtained for each patient before (T0) and after 4 months of starting the treatment (T1) using an intraoral scanner. The T0 to T1 digital model was superimposed to assess the primary outcome, labial movement of the maxillary incisors. For each model, the following secondary outcomes were evaluated: overbite, intermolar width (IMW), incisor leveling, arch perimeter (AP), and mesiodistal angulation. Data analysis included descriptive statistics, paired t tests, independent t tests, one-way ANOVA, and Tukey's HSD test.
Results: There was no significant difference between CA and RIP groups regarding overjet, overbite, incisor leveling, and mesiodistal angulation of the maxillary incisors (P < 0.05). However, a significant difference was found between two groups in IMW, AP, and incisor superimposition (P < 0.05).
Conclusions: The CA group showed a more significant increase in labial movement of maxillary incisors, IMW, and AP compared to the RIP group. However, both treatment protocols were effective in treating anterior crossbite. This study was recorded in the ClinicalTrials.gov database (identifier: NCT06015386).

Dental arch dimensional changes in deep bite adults treated with orthodontic fixed appliances in conjunction with maxillary incisor vs. canine bite turbos during the levelling and aligning phase: a randomized clinical trial.

Introduction: This randomized clinical trial compared arch dimensional changes, dentoskeletal changes, and the rate of overbite correction in deep bite adults treated with fixed appliances and either maxillary incisor bite turbos (IBT) or canine bite turbos (CBT).
Materials And Methods: Forty-six deep bite subjects treated with fixed appliances were randomized into IBT (n = 23) and CBT (n = 23) groups. Changes in intercanine width (ICW), arch height (AH), and Little's Irregularity Index (LII) were analyzed from before treatment (T) to 3 months after aligning with 0.
Background: Tooth wear is an important mechanism for reducing dental dimensions and, consequently, dental crowding. The objective of this cohort study was to examine the relation of tooth wear, adjusted for covariates (age, tooth loss, arch perimeter and intercanine width), on tertiary crowding in Amazon Indigenous populations.
Methods: A sample of 40 Indigenous people in permanent dentition at T0 (baseline) and after 13 years (T1) were evaluated.

Temporomandibular joint osteoarthritis (TMJ OA) is a common degenerative disease characterized by cartilage degeneration. However, the therapeutic strategies aimed to maintain cartilage homeostasis remain unclear. Fostamatinib (Fos) is a potential clinical drug for rheumatoid arthritis (RA) and predicted as target drug for many inflammatory diseases.

Background: Anterior disc displacement (ADD) is the most common type of temporomandibular joint (TMJ) internal derangement and may lead to condylar resorption (CR) during the adolescence period, but the specific malocclusion associated with ADD and CR remains unclear.
Objective: This study aimed to investigate the malocclusion associated with TMJ ADD and CR in adolescents.
Methods: This cross-sectional study included a clinical examination of adolescent patients aged 11-19 years.

Objective: Abnormal mechanical stress is intimately coupled with osteoarthritis. Microtubules play a vital role in the regulation of mechanotransduction and intracellular transport. The purpose of the present study was to investigate the impact of stress-induced microtubule impairment on intracellular transport and lipid droplet (LD) accumulation in chondrocytes.
