Evaluation of oral manifestations and masticatory force in patients with polymyositis and dermatomyositis

Abstract

In conclusion, the present study showed that, patients with IIM diseases have hyposalivation and mucosal alterations, mainly in the form of telangiectasia. They have increased prevalence of dental caries, which may be secondary to the hyposalivation. The masticatory and the upper extremity flexor forces indicate that the weakness of the masticatory muscles can manifest earlier than that of the arms.

Eighteen Months Follow-Up with Patient-Centered Outcomes Assessment of Complete Dentures Manufactured Using a Hybrid Nanocomposite and Additive CAD/CAM Protocol

“…The general improvements in patient satisfaction were in accordance with the study by Katadiyil and co-workers, comparing treatment outcomes from two fabrication techniques (conventional and CAD/CAM) [35]. They reported that patients revealed significantly higher overall patient satisfaction with CAD/CAM complete dentures.…”

“…The nanocomposites with higher elastic moduli were better for our intended application, manufacturing 3D-printed complete dentures, as were better able to withstand higher occlusal forces, being able to avoid deformation and fractures of teeth and the denture base. The maximum masticatory force in some people may reach up to 500 to 700 N/cm 2 [35]. Consequently, the calculated values for E = 6.34 GPa (as compared to 5.46 for E-Dent 100) and for hardness 0.35 GPa (0.32 GPa for E-Dent 100) provided a comfortable mechanical resistance of the 3D-printed nanocomposite to masticatory forces, being suitable for complete denture manufacturing.…”

Periodontal disease in pediatric rheumatic diseases

“…58,59 Alterations in the masticatory system have been identifi ed in JDM patients, such as: hyposalivation, mucosal alterations, mainly in the form of telangiectasia, [58][59][60][61][62][63] and weakness of the masticatory muscles. 58 The reduction of mandibular mobility, particularly mouth opening in active JDM patients reinforces the possibility that this fi nding is an additional manifestation of JDM in the masticatory system and a consequence of muscle weakness. 59 One relevant aspect evidenced in JDM patients was a unique gingival pattern, characterized by gingival erythema, capillary dilation and bush-loop formation (similar to periungual capillary changes observed in nailfold capillaroscopy) associated with cutaneous disease activity.…”

Spontaneous and Bite-Evoked Muscle Pain Are Mediated by a Common Nociceptive Pathway With Differential Contribution by TRPV1

“…These conditions also interfere with normal muscle functions, e.g., limited range of motion in low back pain or decreased bite force in TMJD. Although mechanisms underlying muscle pain have been studied in multiple preclinical models 21,37 , molecular mechanisms and neural circuits underlying spontaneous muscle pain or muscle function-related pain, such as reduced bite force 34,36 , are not well understood. Scarcity of readily available rodent models for assessing spontaneous pain and muscle function-related pain is an impediment to progress.…”
