Abstract Background Since in children and adolescence prevalence is assessed mainly on self‐reported or proxy‐reported signs symptoms; there a need to develop more comprehensive standardised process for the collection of clinical information diagnosis TMD these populations. Objective To new instruments adapt diagnostic criteria temporomandibular disorders (DC/TMD) evaluation adolescents. Method A modified Delphi method was used seek international consensus among experts. Fourteen clinicians...

The aim of the present study was to evaluate tactile detection threshold (TDT), filament-prick pain (FPT), pressure (PPT), and tolerance (PTOL) at multiple measuring points in orofacial region normal subjects. Sixteen males 16 females (age range from 20 41 years) participated. TDT FPT were measured on cheek skin overlying central part masseter muscles (MM), maxillary gingiva, tip tongue, using Semmes-Weinstein monofilaments. PPT PTOL MM, a algometer. intensity during FPT, measurements...

This study was conducted to assess the psychological characteristics of, and determine effectiveness of group cognitive-behavioral (CB) treatment for, patients with burning mouth syndrome (BMS). The baseline 24 female (age 69.7 ± 5.9 years) an identical number healthy control subjects 69.2 5.5 were compared. patient had significantly higher anxiety scores (P < 0.05) at baseline. A brief CB intervention delivered in a small-group format. Two sessions planned 6 months apart. numeric rating...

The Diagnostic Criteria for Temporomandibular Disorders (DC/TMD) use in adults is worldwide. Until now, no version of this instrument adolescents has been proposed.To present comprehensive and short-form adaptations the adult DC/TMD that are appropriate with clinical research settings.International experts TMDs pain psychology participated a Delphi process to identify ways adapting protocol physical psychosocial assessment adolescents.The proposed adaptation defines adolescence as ages 10-19...

In this study, we applied cognitive behavioural intervention to subjects who had painful limited mouth opening, with or without posture correction in daily life. The efficacy of non‐intervention control was then compared it order study the effectiveness as part a biobehavioural therapy. visual analogue scale (VAS) value pain intensity at maximum opening and disturbance life sharply declined group which received only those together although there little difference between groups. Moreover,...

There is general agreement that excessive stress to the bone-implant interface may result in implant overload and failure. Early failure of due loading occurs shortly after uncovering implant. Excess load on a final restoration successful integration can physical structure. Many clinicians believe dental implants risk factor for vertical peri-implant bone loss and/or be detrimental suprastructure prostheses. It has been documented occlusal parafunction, such as, bruxism (tooth grinding...

There have been many reports on fatal distortion of heat-activated acrylic denture-base resin which is still widely used in the field removable prosthodontics. However, these failed to report quantitatively polymerization and thermal shrinkage factors. In present study, we attempted verify that was caused mainly by contraction after processing. Furthermore, examined degree resulting from long, low-temperature processing, compared results with conventional method. The strain gauge...

This study compared pain intensity and psychosocial characteristics between patients with burning mouth syndrome (BMS) those trigeminal neuralgia (TN). Data from 282 BMS 83 TN were analyzed. Patients reported duration of illness: ≤ 6 months was defined as acute illness > chronic illness. Present worst during the past using a 0-10 numeric rating scale (NRS). In addition, depression somatization scores evaluated on questionnaires. significantly higher had worse than did BMS. Pain in patients,...
