Temporomandibular joint (TMJ) and infratemporal fossa (ITF) tumors, even though rare, present diagnostic complexities due to their nonspecific symptoms. Synovial sarcoma comprises 5-10% of adult soft-tissue sarcomas and is uncommon in the head and neck and exceptionally rare in the TMJ/ITF region. We presented a case of monophasic synovial sarcoma affecting the left TMJ/ITF in a 24-year-old man with severe preauricular pain who was misdiagnosed with temporomandibular disorder for 3 years.

Purpose: In this study, we examined the facial, dental, periodontal, and tomographic features associated with excessive gingival display (EGD) when smiling in young adults self-reporting a "gummy smile," categorized by potential etiology.
Methods: The study included 25 healthy adults (18-42 years old; 23 women and 2 men) who self-reported EGD. Participants completed a health questionnaire and underwent a periodontal examination assessing probing depth, clinical attachment level, keratinized gingival width, and gingival thickness (GT).

Objective: The aim of this study was to analyze the effectiveness of L-PRF as a healing agent in the postoperative period of third molar extraction surgeries, as well as to investigate secondary effects, such as the reduction of pain, edema and other discomforts after the surgical intervention.
Materials And Methods: The methodology adopted consisted of carrying out a systematic review of the literature, following the model outlined by the Preferred Reporting Items for Systematic Reviews and Meta-Analyses (PRISMA). The inclusion criteria were previously established according to a systematic review protocol approved by the Prospective Register of Systematic Reviews (PROSPERO) under number CRD42023484679.
Background: Currently, even individuals who do physical activity regularly have some degree of dissatisfaction with their own bodies. The electromagnetic field for supramaximal muscle contraction has been the subject of research. High-intensity supramaximal muscle stimulation (HI-SMS) is a non-invasive technology used to strengthen, firm, and tone the abdominal muscles, arms, buttocks, and thighs and has been indicated for aesthetic purposes.

Objective: The purpose of this study was to evaluate the 3D changes in the upper airway space after maxillomandibular advancement surgery (MMA).
Methods: A retrospective analysis of 56 patients, 21 male and 35 female, with a mean age of 35.
Camurati-Engelmann Disease (CED), also known as progressive diaphyseal dysplasia, is a rare congenital disorder inherited in an autosomal-dominant pattern, most commonly affecting the skull and diaphysis of long tubular bones. Clinical symptoms start in early age and include ostealgia, muscle atrophy and weakness in the lower limbs, generalized fatigue in addition to gait disturbances (Garcia Armario and Lebron, 2011, Andreu-Arasa et al., 2019; Fyrgiola et al.

Materials And Methods: It was a retrospective cohort study.
Background: Dento-skeletal deformities are treated combining orthodontic treatment with orthognathic surgery. One of the techniques most used in this type of surgery is the sagittal osteotomy of the mandible. This technique offers many advantages, but within its disadvantages is the inferior alveolar nerve paresthesia.

The aim of this study was to compare the morphometric and bone density changes after using two different bovine bone graft blocks in segmental osseous defects in the mandible of rabbits following different postoperative periods.
Material And Methods: Critical size segmental defects were surgically created bilaterally in the jaw of 18 rabbits.
Three-dimensional (3D) software has revolutionized planning in orthognathic surgery. This technology allows the simulation of surgical movements and evaluation of the volume and area of the pharyngeal airway space (PAS), which are not possible with two-dimensional (2D) software. Many patients undergo orthognathic surgery to improve occlusion and facial profile.

However, paresthesia is common in the postoperatory, sometimes permanent, and undesirable fractures in the subcondylar region can occur leading to longer operative time and extraoral scars. The short lingual split technique is an easy technique that simplifies the horizontal osteotomy of the ramus and decreases the risk of undesirable fractures with a neurosensitive recovery of patients in a much shorter time because of minor trauma and nerve manipulation during the execution.
