Background: Myofascial pain syndrome (MPS) is a particular type of temporomandibular joint disorder. Research findings comparing various treatment approaches are scarce and controversial. Therefore, this study aimed to compare the effectiveness of ultrasound therapy, stabilization splint, TheraBite device, and masticatory muscle exercises in reducing pain intensity and improving mandibular mobility in patients with MPS.

Objective To evaluate the relative efficacy of periodontally accelerated osteogenic orthodontics (PAOO) compared to conventional fixed appliances in correcting lower anterior teeth crowding using a non-extraction treatment approach. Material and methods A single-center, two-arm, parallel-group randomized controlled trial was conducted on 38 patients (9 males, 29 females) with moderate crowding. These patients did not require premolar extraction and were randomly allocated into two treatment groups: the PAOO group and the conventional orthodontic treatment group.

Article Synopsis
  • * A study in Yemen involving 310 dental health professionals revealed a low level of ergonomic awareness and a significant prevalence of MSDs, particularly in the neck, lower back, and shoulders.
  • * The findings highlight the need for preventive measures, such as adopting ergonomic positions, using appropriate equipment, and incorporating exercise and breaks into their work routines.

Objective: The primary aim of this study was to determine the effect of implant-supported porcelain-fused-to-metal (PFM) and indirect-composite-resin (ICR) fixed dental prostheses on peri-implant marginal bone resorption (MBR) in custom-made anatomic modified zirconia dental implants.

Methods: A prospective randomized controlled clinical trial was conducted. Participants with premolars indicated for dental extractions were recruited into this study to receive a single-unit implant-supported fixed dental prosthesis.

Purpose: The primary objective of this randomized controlled trial is to compare the clinical impact of using crowns manufactured by 3D printing and direct composite celluloid crowns as a final restoration for primary molars after pulpotomy procedures.

Material And Methods: Fifty primary molars selected from the children needing treatment at the Pediatric Dentistry Clinic at Damascus University Faculty of Dentistry were randomized by using SPSS and divided into 2 groups based on fabricating methods: Group A: 3D-printed crowns with the utilization of biocompatible light-curing composite, and Group B: Crowns were made directly using composite carried out by prefabricated celluloid crown. The evaluation team assessed the crowns in each group using the United States Public Health Service (USPHS) criteria for retention, marginal integrity, and gingival health at baseline, followed by 3 follow-up sessions at 3, 6, and 12 months.

Objectives:  This randomized clinical trial aimed to evaluate clinical outcomes of two types of esthetic crowns fabricated using a three-dimensional (3D) dental printer and computer-aided design and manufacturing (CAD/CAM) system as an alternative full-coronal restoration for extensively carious pulp-treated primary molars.

Materials And Methods:  Randomization was done for 50 lower primary molars in 50 child patients, split into two groups based on the fabrication method used: Group A: CAD/CAM crowns using polymethyl methacrylate (PMMA) blocks and Group B: 3D dental printed crowns using GC photopolymer resin. All crowns were evaluated at baseline and at 3rd, 6th, and 12th months using the U.

Article Synopsis
  • The study investigates the link between psychosocial stress and temporomandibular disorder (TMD) by comparing salivary cortisol levels and stress/depression scores between TMD patients and matched controls.
  • Conducted with 60 TMD patients and an equally sized control group, it utilized the Perceived Stress Scale (PSS) and measured salivary cortisol to assess stress levels.
  • Results indicated significant differences in stress measures between the two groups, highlighting the role of psychosocial stress in TMD, with a higher prevalence in women and similar stress levels among different TMD sub-types.
