Nutrition and chronic musculoskeletal pain: A narrative review and directions for temporomandibular disorder research and management.

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.

Evaluation of one versus two glaze firings on the color stability and mechanical properties of an extrinsically characterized monolithic CAD-CAM lithium disilicate glass ceramic.

Purpose: To evaluate the effects of 1 versus 2 glaze firings on the color and mechanical properties of an extrinsically characterized lithium disilicate ceramic after thermal cycling, brushing, or both.

Materials And Methods: Eighty specimens were divided into 2 groups: 1 glaze firing (GL1) and 2 glaze firings (GL2). Each group was subdivided into 4 groups (n = 10), according to the experimental conditions: thermal-cycling, brushing, thermal-cycling + brushing, and immersion in distilled water (control).

Management of Cancer Therapy-Induced Oral Mucositis Using Photobiomodulation Therapy: An Overview of Systematic Reviews.

To systematically summarize the evidence for photobiomodulation therapy (PBMT) in the prevention and treatment of oral mucositis (OM) in patients undergoing cancer treatment. An electronic search was conducted in 8 databases and grey literature. PBMT is recommended for the management of OM resulting from cancer treatment, with several systematic reviews (SRs) being published in recent years on this topic.

Antimicrobial Photodynamic Therapy as a Technique for Decontamination of Acrylic Resin Devices Provided by Different Dental Laboratories.

Dentures, occlusal splints, surgical guides and orthodontic appliances are examples of acrylic resin devices made in dental laboratories, which must be disinfected and even sterilized before insertion into the oral cavity. This study evaluated the antimicrobial effect of photodynamic therapy (PDT) applied to acrylic resin specimens received from different laboratories. Three hundred standardized specimens were ordered from six randomly selected laboratories registered in the Council of Dentistry of Ceará (n=50).

Gluten-Free Diet Reduces Pain in Women with Myofascial Pain in Masticatory Muscles: A Preliminary Randomized Controlled Trial.

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.

Candida biofilm matrix as a resistance mechanism against photodynamic therapy.

Background: Antimicrobial photodynamic therapy (aPDT) efficiency on Candida albicans is recognized in free-floating cultures. Though, the lack of aPDT effectiveness against C. albicans organized in biofilms is still unclear.

Clinical study of the biofilm of implant-supported complete dentures in healthy patients.

Objective: The purpose of this study was to quantify the area covered by biofilm and identify bacteria and yeasts present in mandibular acrylic resin full-arch implant-supported fixed prostheses.

Background: Biofilm control of implant-supported fixed prosthesis is hampered by their design, and it can cause oral and systemic problems, mainly in immunocompromised patients like the elder. Knowledge about microbiota reinforces the awareness about the need for periodic professional cleaning maintenance.

Regimen and different surfaces interfere with photodynamic therapy on Candida albicans biofilms.

The aim of this study is to compare antimicrobial photodynamic therapy (aPDT) against Candida albicans biofilms formed on two different substrates - acrylic resin or bottom of polystyrene plate; and two aPDT application regimens - twice-daily over the course of 48 h or single treatment after 48 h biofilm formation. C. albicans SN425 biofilms cultivated on Roswell Park Memorial Institute medium were incubated for 5 min with toluidine blue O (44 μM) used as a photosensitizer before red light (635 nm; 175.

Orofacial pain secondary to acoustic neuroma-A case report.

Aim: The present study aimed to report a case of orofacial pain secondary to acoustic neuroma (AN).

Methods And Results: A 66-year-old female presented with unilateral facial pain and odontalgia. The pain was described as throbbing, dull, and constant.

Effects of low-level laser therapy on bone regeneration of the midpalatal suture after rapid maxillary expansion.

This study evaluated the effect of low-level laser therapy (LLLT) on bone regeneration at the midpalatal suture (MPS) after rapid maxillary expansion (RME), using cone beam computed tomography. Fourteen 8-14-year-old patients with transverse maxillary deficiency underwent RME with a Hyrax-type expander activated with one full turn after installation and two half turn daily activations until achieving overcorrection. Patients were randomly assigned to either a control group (RME alone, n = 4) or an experimental group (n = 10) in which RME was followed by 12 LLLT sessions (GaAlAs, p = 70 mW, λ = 780 nm, Ø = 0.

Effect of toothbrushes and denture brushes on heat-polymerized acrylic resins.

It is important to choose an appropriate brush for denture cleaning to prevent damage to the surface properties of prosthetic devices. The purpose of this study was to evaluate the abrasiveness of toothbrushes and denture brushes on boiled and microwave-processed acrylic resins. Specimens of 4 resin brands were prepared (n = 30).

Photosensitization of in vitro biofilms formed on denture base resin.

Statement Of Problem: Proper sterilization or disinfection of removable prostheses and surgical guides has been problematic in dental practice because of the absence of simple and low-cost techniques that do not cause damage to acrylic resins.

Purpose: The purpose of this study was to study the effect of photodynamic therapy against Streptococcus mutans, Staphylococcus aureus, Escherichia coli, Pseudomonas aeruginosa, and Candida albicans biofilms formed on acrylic resin specimens.

Material And Methods: The specimens were sterilized in ethylene oxide gas and submitted to in vitro biofilm growth.

Effects of 2 polishing techniques and reglazing on the surface roughness of dental porcelain.

The aim of this study was to compare the effect of 2 polishing systems and reglazing of dental porcelain through a quantitative and qualitative analysis of surface roughness using a stylus profilometer and scanning electron microscope. Fifteen porcelain specimens (10 x 3 x 3 mm) were used. On 1 surface of each block, a layer of glaze was applied, and surface roughness (Ra) was analyzed.

Effect of surface pretreatments on the microtensile bond strength of lithium-disilicate ceramic repaired with composite resin.

The aim of this study was to evaluate the influence of ceramic surface treatments and silane drying temperature on the microtensile bond strength (µTBS) of a resin composite to a lithium disilicate ceramic. Twenty blocks (7x7x5 mm) of lithium disilicate-based hot-pressed ceramic were fabricated and randomly divided into 4 groups: G1: acid etching with 9.5% hydrofluoric acid for 20 s and drying silane with room-temperature air; G2: acid etching with 9.
