Retrospective Study of the Epidemiological Profile of Facial Trauma Related to Violence.

Facial trauma is now considered an epidemic due to its high incidence. This type of injury represents an impact on the social, psychological and professional life of the victim. It may be associated with poor protection and exposure of this region of the body, as well as with the attempt to disfigure the face of victims of aggression, to affect their identity and self-image.

Management of excessive gingival display using botulinum toxin type A: a descriptive study.

Botulinum toxin is a protease used by the bacterium Clostridium botulinum that causes chemical denervation of skeletal muscles, producing a temporary weakening of muscle activity. Despite having a transitory effect, the application of botulinum toxin has been identified as an alternative for correcting an excessive gingival display (EGD). However, studies evaluating the maintenance of long-term results of botulinum toxin remain scarce.

Comparative effectiveness of photobiomodulation and manual therapy alone or combined in TMD patients: a randomized clinical trial.

The effectiveness of photobiomodulation (PBM) and manual therapy (MT), alone or combined (CT), were evaluated in pain intensity, mandibular movements, psychosocial aspects, and anxiety symptoms of temporomandibular disorder (TMD) patients. Fifty-one TMD patients were randomly assigned to three groups: the PBM group (n = 18), which received PBM with 808 nm, 100 mW, 13.3 J/cm2, and 4 J per point; the MT group (n=16) for 21 minutes each session on masticatory muscles and temporomandibular joint TMJ; and the CT group (n = 17), applied during twelve sessions.

Influence of a Magnetic Field and Laser Therapy on the Quality of Mandibular Bone During Distraction Osteogenesis in Rabbits.

Purpose: This study evaluated the use of low-level laser therapy (LLLT) and exposure to a magnetic field (MF) during distraction osteogenesis.

Materials And Methods: The sample consisted of 18 rabbits divided into 3 groups of 6 animals each: control, MF exposure (briefly, magnetized gold-coated washers were placed next to the distractor device), and LLLT exposure (830 nm applied every 48 hours over 4 points [dose, 5 J/cm] during the consolidation period). The same distraction osteogenesis protocol was used in all 3 groups (0.

Finite element analysis of masticatory stress on neoformed bone tissue after distraction osteogenesis and low-level laser therapy: a pilot study.

Objective: This study aimed to understand the action of masticatory forces on an implant virtually introduced into the sheep mandible after distraction osteogenesis and low-level laser therapy (LLLT) by using finite element analysis.

Background Data: Distraction osteogenesis as an alternative for bone reconstruction that may be used in the treatment of deformities.

Methods: Four ewes underwent distraction osteogenis to elongate the left mandibular body by 15 m, and three of them underwent LLLT with the purpose of improving bone properties.

Oral myiasis.

Human myiasis results from parasitic tissue infestation by maggots. It often develops in open or necrotic wounds and has its highest prevalence among poor populations in tropical regions. This study reports 2 cases of human myiasis in the oral cavity and describes its clinical aspect and treatment.

A preliminary study of hardness and modulus of elasticity in sheep mandibles submitted to distraction osteogenesis and low-level laser therapy.

Objectives: To investigate the quality of newly formed bone in sheep mandibles submitted to distraction osteogenesis and low-level laser therapy (LLLT), based on hardness and modulus of elasticity values. The ideal moment for laser application (during the latency/activation period vs. during the bone consolidation period) was also evaluated.

Effect of low-level laser therapy after implantation of poly-L-lactic/polyglycolic acid in the femurs of rats.

This study evaluated the use of red and infrared lasers on tissue surrounding the femurs of 60 rats randomly divided into three groups after implantation of bioabsorbable plates. The control group were not subjected to laser irradiation; group A was treated with red laser [indium-gallium-aluminum-phosphide (InGaAlP) laser, wavelength 685 nm, 35 mW, continuous wave (CW), Ø = 0.06 cm, 2.
