The natural dynamics of the jaw during physical activity and its physiological mechanisms are not fully understood. However, teeth clenching during certain sports activities may be associated with increased strength, power, flexibility, and performance. This behavior is termed awake bruxism (AB) and can lead to intraoral damage, highlighting the importance of patient education and management.

Background: Temporomandibular disorder (TMD) is the main chronic pain that affects the face, and it is associated with dietary changes due to pain and dysfunction. However, there is a scarcity of studies on its impact on nutrition and vice versa.

Objectives: To assess and compare the intake of energy and nutrients among chronic TMD myalgia and asymptomatic women and to evaluate data according to dietary reference intakes (DRI) and the World Health Organization (WHO) values.

Article Synopsis
  • CrossFit® is a popular training method aimed at improving physical fitness, but there's limited research on bruxism (teeth grinding/clenching) among its practitioners, despite previous suggestions of increased clenching during weightlifting.
  • The study examined bruxism signs in 57 CrossFit® practitioners, using various questionnaires and assessments to gather data on oral behaviors and related health metrics.
  • Findings showed a high prevalence of teeth clenching (61.4%) and dental issues like tooth wear and lesions, but no clear link was established between bruxism signs and the intensity of physical activity, highlighting the need for dental health education in CrossFit® communities.

Background: Recent evidence suggests neuro-immune mechanisms may link dietary patterns to chronic painful conditions (CPC). In the research field of oro-facial pain (OFP), studies focuses primarily on dietary mechanical limitations due to pain and dysfunction.

Objective: This narrative review aimed to overview the role of nutrition on CPC, with emphasis on temporomandibular disorder (TMD), enlightening OFP researcher on dietary assessment possibilities and providing directions for studies in the field of OFP and nutrition.

Purpose: To evaluate the vertical misfit, stress distribution around dental implants, and cantilever fracture strength of 3-unit implant-supported cantilever fixed partial dentures (FPDs) using frameworks made from different materials and manufacturing techniques.

Materials And Methods: Forty FPDs were fabricated and divided into 5 groups (n = 8) based on the framework material used: LAS Co-Cr (Conventional casting-laser welding); TIG Co-Cr (Conventional casting -TIG welding); OP Co-Cr (Conventional casting-one-piece); CAD Co-Cr (CAD-CAM); and CAD Zr (CAD-CAM ZrO). The vertical misfit was evaluated before porcelain application (T1) and before (T2), and after thermomechanical cycling (T3) by stereomicroscopy.

Aims: To determine whether there is an association between gene polymorphisms and patients with painful temporomandibular joint (TMJ) clicking when compared to patients with painless TMJ clicking and a healthy control group.

Methods: In this pilot study, the genotypic and allelic frequencies of candidate single-nucleotide polymorphisms (SNP) were compared among 60 individuals divided equally into three groups: patients with painful TMJ clicking (n = 20); patients with painless TMJ clicking (n = 20); and healthy controls (n = 20). Participants were genotyped for the following SNPs using real-time polymerase chain reaction: MMP1 -16071G/2G, COMT Val158Met, TNFα -308, IL1β +3954, IL6 -174, and IL10 -1082.

Objective: This study aimed to evaluate and compare pain intensity and Oral Health-related Quality of Life (OHRQoL) in women with temporomandibular disorder (TMD) before (T1) and during (T2) COVID-19 pandemic.

Materials And Methods: Sample was composed of forty-one female participants with painful TMD, who presented for TMD treatment. Subjects were asked to indicate their pain intensity and to answer the Oral Health Impact Profile-14 (OHIP-14).

Aims: To evaluate the efficacy of a gluten-free diet (GFD) as a treatment modality for pain management in women with chronic myofascial pain in masticatory muscles.

Methods: In this randomized controlled trial, 39 female subjects were evaluated according to the Research Diagnostic Criteria for Temporomandibular Disorders (RDC/TMD) and divided into three groups: a healthy group (n = 14; mean ± SD age = 34.57 ± 9.

Aims: This case report aimed to discuss the multifactorial etiology and also the management of temporomandibular disorders (TMD) by addressing important associated psychosocial and biological factors, emphasizing the interaction between these factors and a probable genetic predisposition.

Methods And Results: A 21-year-old female patient was evaluated according to Research Diagnostic Criteria for TMD and diagnosed with arthralgia, myofascial pain, disc displacement without reduction, and temporomandibular joint (TMJ) degenerative disease. TMJ alterations were confirmed through magnetic resonance imaging and cone-beam computed tomography.

Objective: The aim of this study was to assess the correlation of inflammatory and pain genes polymorphisms with the presence of temporomandibular disorder (TMD) patients and with pressure pain sensitivity.

Design: Data was collected from 268 consecutive subjects at Bauru School of Dentistry. Subjects aged younger than 20 years, with dental and neuropathic pain, sinusitis, cognitive and neurologic disorder were excluded.

Oral rehabilitations in esthetic regions may be challenging when different prosthodontic modalities must be combined with interventions on gingival tissues to create a harmonious smile for the patient. This case report describes the treatment of a 36-year-old man with an esthetically compromised maxillary anterior region by means of periodontal microsurgery, an implant-supported dental prosthesis, and tooth-supported crowns. Combined esthetic-functional planning based on clinical and radiographic examinations, photographs, and a diagnostic wax-up led to correction of the gingival contour and thickness by means of periodontal microsurgery; customization of an implant-supported zirconia abutment with the application of feldspathic porcelain; fabrication of a lithium disilicate ceramic infrastructure to mask darkened substrate; and fabrication of lithium disilicate ceramic definitive restorations.

Aims: To assess the influence of myofascial temporomandibular disorder (TMD) pain on the pressure pain threshold (PPT) of masticatory muscles in women during a migraine attack.

Methods: The sample comprised 34 women, 18 to 60 years of age, with a diagnosis of episodic migraine previously confirmed by a neurologist. All subjects were evaluated using the Research Diagnostic Criteria for TMD (RDC/TMD) to determine the presence of myofascial pain.

Many conditions may cause painful symptoms in orofacial structures. Among the chronic conditions that affect this area, temporomandibular disorders are the most common. Temporomandibular Disorder is a collective term that includes a number of clinical complaints involving the masticatory muscles, the Temporomandibular Joint and associated structures.
