Achieved competences in temporomandibular disorders/orofacial pain: a comparison between two dental schools in Europe
The aim was to study achieved competences in temporomandibular disorders (TMD)/orofacial pain (OP) at two universities by comparing student's knowledge and understanding, satisfaction with their education and confidence in their clinical competences of TMD/OP
Using Teledentistr y to Improve Access to Dental Care for the Underser ved
Advances in dental care have documented that early diagnosis, preventive treatments, and early intervention can prevent or reduce the progress of most oral diseases, conditions that, when left untreated, can have painful, disfiguring, and lasting negative health consequences. 1 Unfortunately, millions of American children and adults lack regular access to routine dental care, and many of them suffer needlessly with disease that inevitably results in significant decrements in their quality of life. Problems in access to oral health care cut across economic, geographic, and ethnographic lines. Racial and ethnic minorities, people who have disabilities, and those from low-income families, particularly children, are especially hard hit. In most rural areas in this country, especially, there are many barriers to dental health care, including geographic remoteness, sparse population, adverse seasonal weather and road conditions, poor or no public transportation, poverty and lack of health insurance, a less mobile aging population, culturally specific health care needs of many groups (especially American Indian and immigrant populations); a low number of dentists relative to total population, and a scarcity of specialty and subspecialty dentists. Teledentistry is an exciting new area of dentistry that uses electronic health records, telecommunications technology, digital imaging, and the Internet to link health care providers in rural or remote communities to enhance communication, the exchange of health information, and access to care for underserved patients.

Pathophysiology, diagnosis and treatment of somatosensory tinnitus: a scoping review
Somatosensory tinnitus is a generally agreed subtype of tinnitus that is associated with activation of the somatosensory, somatomotor, and visual-motor systems. A key characteristic of somatosensory tinnitus is that is modulated by physical contact or movement. Although it seems common, its pathophysiology, assessment and treatment are not well defined. We present a scoping review on the pathophysiology, diagnosis, and treatment of somatosensory tinnitus, and identify priority directions for further research.
Methods: Literature searches were conducted in Google Scholar, PubMed, and EMBASE databases. Additional broad hand searches were conducted with the additional terms etiology, diagnose, treatment.
Results: Most evidence on the pathophysiology of somatosensory tinnitus suggests that somatic modulations are the result of altered or cross-modal synaptic activity within the dorsal cochlear nucleus or between the auditory nervous system and other sensory subsystems of central nervous system (e.g., visual or tactile). Presentations of somatosensory tinnitus are varied and evidence for the various approaches to treatment promising but limited.
Discussion and Conclusions: Despite the apparent prevalence of somatosensory tinnitus its underlying neural processes are still not well understood. Necessary involvement of multidisciplinary teams in its diagnosis and treatment has led to a large heterogeneity of approaches whereby tinnitus improvement is often only a secondary effect. Hence there are no evidence-based clinical guidelines, and patient care is empirical rather than research-evidence-based. Somatic testing should receive further attention considering the breath of evidence on the ability of patients to modulate their tinnitus through manouvers. Specific questions for further research and review are indicated
Evaluation of Surgically Retrieved Temporomandibular Joint Alloplastic Implants: Pilot Study
PURPOSE: The purpose of this study was to perform a retrieval analysis of temporomandibular joint (TMJ) alloplastic interpositional implants and test possible correlation between implant failure features and patient clinical outcomes. In addition, we investigated the implants' surface and examined the foreign body reaction associated with different types of alloplastic materials.
MATERIALS AND METHODS: Twelve implants (Proplast/Teflon [Vitek, Houston, TX] and Silastic [Dow Corning, Midland, MI]) were surgically removed from the patients' TMJs. Implant surface failure features (fracture length, perforation of the implants) were observed using stereomicroscopy and recorded for description of the failure mechanisms and to statistically compare with clinical outcomes. Patients' clinical data (pain symptoms and mandibular function) were collected and examined. Clinical outcomes were obtained relative to symptom severity (Symptom Severity Index [SSI]) and jaw function (modified Mandibular Function Impairment Questionnaire [mMFIQ]). Peri-implant soft tissues and implants were analyzed with light microscopy and stereo zoom microscopy. Electron microprobe analysis of implant fragments and peri-implant tissues was performed.
RESULTS: The statistical results showed that only the presence of implant perforation was statistically associated with the SSI, specifically with the pain tolerability dimension. No statistical association was seen between any of the other implant failure predictors and the SSI and between the predictors and the mMFIQ. Stereo zoom microscopy suggested that Proplast/Teflon implants (n = 7) were susceptible to perforation, layer tearing, fracture and fiber extrusion. The Silastic implants (n = 3) revealed a possible center perforation with fracture lines towards the periphery and fiber extrusion. Teflon implant wear debris particles appear to trigger a multinucleated giant cell foreign body reaction.
CONCLUSION: Facial pain was a significant correlate to perforation and breakdown of the alloplastic TMJ interpositional implants, and most likely was the reason for implant removal
