Thermographic findings related to facial pain - a survey of 40 subjects.

Objective: The purpose of this study was to assess how thermography findings relate painful symptoms and signs of temporomandibular disorders (TMD).

Methods: Thermography, combined with chewing of paraffin wax, was performed on 40 subjects. The results were analyzed according to gender and pain-related TMD symptoms and clinical signs.

Topical tacrolimus, triamcinolone acetonide, and placebo in oral lichen planus: a pilot randomized controlled trial.

Objective: To carry out a double-blind randomized controlled trial (RCT) to compare the effectiveness of topical tacrolimus (TAC), triamcinolone acetonide (TRI), and placebo (PLA) in symptomatic oral lichen planus (OLP).

Subjects And Methods: A clinical score (CS, range 0-130) was developed to measure the clinical signs and symptoms of OLP. Twenty-seven OLP patients with a CS of ≥20 were randomly allocated to receive 0.

Effect of display type, DICOM calibration and room illuminance in bitewing radiographs.

Objectives: To compare observer performance in the detection of both anatomical structures and caries in bitewing radiographs using consumer grade displays with and without digital imaging and communications in medicine (DICOM) calibration, tablets (third generation iPad; Apple, Cupertino, CA) and 6-megapixel (MP) displays under different lighting.

Methods: 30 bitewing radiographs were blindly evaluated on four displays under bright (510 lx) and dim (16 lx) ambient lighting by two observers. The dentinoenamel junction, enamel and dentinal caries, and the cortical border of the alveolar crests were evaluated.

Root resorptions related to ectopic and normal eruption of maxillary canine teeth - A 3D study.

Objective: To assess the incidence and severity of root resorption of maxillary incisors caused by ectopically and normally erupting maxillary canines and to analyse factors influencing root resorption of incisors using cone beam computed tomography.

Subjects And Methods: The study sample comprised 59 patients with a total of 80 canines. Forty-six of the canines, in 37 patients, were defined as ectopic and 34 canines, in 22 patients, were defined as normal.

Comparison between DICOM-calibrated and uncalibrated consumer grade and 6-MP displays under different lighting conditions in panoramic radiography.

Objectives: To compare observer performance in the detection of anatomical structures and pathology in panoramic radiographs using consumer grade with and without digital imaging and communication in medicine (DICOM)-calibration and 6-megapixel (6-MP) displays under different lighting conditions.

Methods: 30 panoramic radiographs were randomly evaluated on three displays under bright (510 lx) and dim (16 lx) ambient lighting by two observers with different years of experience. Dentinoenamel junction, dentinal caries and periapical inflammatory lesions, visibility of cortical border of the floor and pathological lesions in maxillary sinus were evaluated.

Healing of rabbit calvarial critical-sized defects using autogenous bone grafts and fibrin glue.

Purpose: This study aimed to evaluate ossification of cranial bone defects comparing the healing of a single piece of autogenous calvarial bone representing a bone flap as in cranioplasty compared to particulated bone slurry with and without fibrin glue to represent bone collected during cranioplasty. These defect-filling materials were then compared to empty control cranial defects.

Methods: Ten White New Zealand adult male rabbits had bilateral critical-sized calvarial defects which were left either unfilled as control defects or filled with a single full-thickness piece of autogenous bone, particulated bone, or particulated bone combined with fibrin glue.

Comparison of consumer grade, tablet and 6MP-displays: observer performance in detection of anatomical and pathological structures in panoramic radiographs.

Objective: To compare observer performance in the detection of anatomical structures and pathology in panoramic radiographs using a consumer grade display and tablet (3(rd) generation iPad; Cupertino, CA, USA) under suboptimal conditions compared to 6 MegaPixels (6 MP) display under dim lighting conditions.

Study Design: Thirty panoramic radiographs were selected. All images were blindly evaluated on three displays by two observers with different amounts of experience.

Healing of extraction sockets in collagenase-2 (matrix metalloproteinase-8)-deficient mice.

Matrix metalloproteinase-8 (MMP-8) participates in skin wound healing and inflammation. We hypothesized that MMP-8 plays a role in wound healing after tooth extraction and in periapical inflammation. Bone formation, collagen metabolism, and inflammation in tooth extraction socket and in periapical lesions were analyzed in wild-type mice and in MMP-8-deficient (MMP-8(-/-)) mice.
