Counterclockwise maxillomandibular advancement surgery and disc repositioning: can condylar remodeling in the long-term follow-up be predicted?

This study investigated predictive risk factors of condylar remodeling changes after counterclockwise maxillomandibular advancement (CCW-MMA) and disc repositioning surgery. Forty-one female patients (75 condyles) treated with CCW-MMA and disc repositioning had cone beam computed tomography (CBCT) scans taken pre-surgery, immediately after surgery, and at an average 16 months post-surgery. Pre- and post-surgical three-dimensional models were superimposed using automated voxel-based registration on the cranial base to evaluate condylar displacements after surgery.

Cone beam computed tomography evaluation of midpalatal suture maturation in adults.

The aim of this study was to evaluate midpalatal suture maturation in adults, as observed in cone beam computed tomography (CBCT) images. CBCT scans from 78 subjects (64 female and 14 male, age range from 18 to 66 years) were evaluated. Midpalatal suture maturation was verified on the central cross-sectional axial slice in the superior-inferior dimension of the palate, using methods validated previously.

Failure torque of ceramic neck titanium implant.

Statement Of Problem: Dental implants are typically made of titanium. However, with the current systems on the market, the implant neck often shows through the gingival tissues as a black or dark gray line and/or as a grayish discoloration of the peri-implant soft tissue.

Purpose: The purpose of this in vitro study was to test a new implant design.

An appropriate Wnt/β-catenin expression level during the remodeling phase is required for improved bone fracture healing in mice.

Accumulating evidence demonstrates that the Wnt/β-catenin signaling pathway plays a dominant role in bone repair. However, the role of Wnt/β-catenin signaling in the remodeling phase during bone fracture healing is currently unknown. In the present study, β-catenin was activated at different levels or deleted in mice at the late stage of fracture healing, and the effects on healing quality were investigated.

Historical Perspectives on the Use of Microscopes in Dentistry.

The use of microscopes in dentistry has become quite popular since the late 1980s. However, its origin for dental applications can be traced to the early 20th century, when a microscope, invented by an American biologist named Greenough, working in the Zeiss Company, was adapted for use in dentistry. Initially it had been used in botany, metallurgy, and zoology, in addition to revolutionizing the study of coral and entomology.

Origins of the Electronic Apex Locator - Achieving Success with Strict Adherence to Business.

Current history would have you believe that the evolution and development of the electronic apex locator for use during root canal procedures emanated from the work of Suzuki in 1942, which was developed as a product by Sunada in 1962. Yes, this is partly correct, however the concept of using electrical means to locate the ends of root canals was brought to the dental profession as early as 1918 by Dr. Levitt Ellsworth Custer, which was not addressed until Suzuki revisited Custer's concepts.

Effects of bone grafting, performed with corticotomies and buccal tooth movements, on dehiscence formation in dogs.

Introduction: A randomized split-mouth experiment was performed in dogs to determine the effects of bone grafting, together with corticotomies and buccal tooth movements, on dehiscence formation.

Methods: Bilateral full-thickness mucoperiosteal buccal flaps were raised, and corticotomies were performed with a piezosurgery unit adjacent to the maxillary second premolars in 7 dogs. The experimental (graft+) side received a demineralized freeze-dried allograph and a resorbable collagen membrane.

Longitudinal cephalometric growth of untreated subjects with Class II Division 2 malocclusion.

Introduction: Our objective was to evaluate the craniofacial growth of subjects with untreated Class II Division 2 malocclusion.

Methods: A mixed longitudinal sample of 39 white Class II Division 2 subjects was analyzed at 5 time points: T1 (6 or 7 years), T2 (9 or 10 years), T3 (12 or 13 years), T4 (15 or 16 years), and T5 (18 or 19 years). They were compared with an age- and sex- matched sample of Class I controls.

Does Orthognathic Surgery Cause or Cure Temporomandibular Disorders? A Systematic Review and Meta-Analysis.

Purpose: There is still controversy about whether orthognathic surgery negatively or positively affects temporomandibular disorders (TMDs). The purpose of this study was to determine whether orthognathic surgery has a beneficial or deleterious effect on pre-existing TMDs.

Materials And Methods: A systematic review and meta-analysis were conducted based on Preferred Reporting Items for Systematic Reviews and Meta-Analyses (PRISMA) guidelines.

Angiopoietin-2 is expressed in oral Kaposi's sarcoma.

Background: Kaposi's sarcoma (KS) persists today as a highly prevalent vascular cancer, often found in HIV patients. Studies have shown that angiopoietin 2 (Ang2), a pro-angiogenic protein, is involved in the pathogenesis of this tumor. However, expression of this protein has not been investigated in oral KS lesions.

Historical Perspectives on Core-Carrier Gutta-Percha Obturation.

Dr. William Ben Johnson introduced the contemporary use fo core-carrier technology for root canal obturation in the late 1970s. This technology has undergone multiple enhancements since its commercial introduction in the early 1990s and has provided a unique clinical treatment regimen for clinicians globally.

Finding Small Root Canals.

One of the main reasons for failure of teeth that have been root treated is the inability to locate and clean canals that are very small or not identified by the clinician. In contemporary practice the use of dyes, such as methylene blue, or magnificatin, such as the microscope are used rotinely in these situations to find the canal orifice in the pulp chamber. Prior to this, other more aggressive methods have been used, such as that identified in 1920.

Laser Assisted Non-surgical Periodontal Therapy: A Double Blind, Randomized Clinical Trial.

The objective of this study was to examine potential benefits of using laser therapy for secular decontamination in conjunction with scaling and root planing in the treatment of chronic periodontitis. The study was performed on 173 teeth in 14 patients in a split-mouth design, one side received scaling and root planing followed by laser therapy using a carbon dioxide (CO) laser with an ablative handpiece (test group); the contralateral side received scaling and root planing without laser (control group). Clinical and laboratory parameters were evaluated prior to treatment and at 3 and 6 months following therapy; clinical measurements were performed by two blinded examiners.

Wnt3α and transforming growth factor-β induce myofibroblast differentiation from periodontal ligament cells via different pathways.

Myofibroblasts are specialized cells that play a key role in connective tissue remodeling and reconstruction. Alpha-smooth muscle actin (α-SMA), vimentin and tenascin-C are myofibroblast phenotype, while α-SMA is the phenotypic marker. The observation that human periodontal ligament cells (hPDLCs) differentiate into myofibroblasts under orthodontic force has provided a new perspective for understanding of the biological and biomechanical mechanisms involved in orthodontic tooth movement.

Application of optogenetics-mediated motor cortex stimulation in the treatment of chronic neuropathic pain.

Motor cortex stimulation provides an alternate approach for intractable pain treatment. Optogenetic manipulation can produce gain- or loss-of-function in specific type of cells following light application. This state-of-the-art technology may be used in motor cortex stimulation to produce circuit-specific neuromodulation and regulate neuronal activities in motor cortex, thereby treating pain in the clinic.
