OBJECTIVES To measure the temperature rise induced during visible light curing of modern resin-containing dental materials and the effect of dentine sections in reducing this temperature rise. METHODS A variety of newly introduced resin-containing materials were investigated, including flowable, packable and conventional hybrid composites, as well as a(More)
OBJECTIVES To examine the effect of composite shade, increment thickness and curing light characteristics on the temperature rise associated with composite photocuring. METHODS Four shades (C2, A4, B1 and B3), four sample thicknesses (2, 3, 4 and 5 mm) of a hybrid resin composite and two curing units, one with two modes of curing, were investigated. The(More)
A prospective study was undertaken to assess the relationship between recrudescent herpes labialis and host iron status. Forty-one patients with recrudescent herpes labialis, proven by herpes simplex virus isolation, were studied along with an equal number of age-and-sex matched control subjects. The iron status of patients and controls were assessed by(More)
We studied 45 patients with malar fractures who had some degree of infraorbital nerve deficit. Thermographic facial images failed to show any substantial changes in the temperature profiles of the affected and the normal control sides in relation to reco very of their facial sensation. Although some patients who had thermography on the day of injury showed(More)
In the preparation of osseointegrated dental implant sites, the use of bone drilling with conventional external irrigation has been shown to be thermally non-injurious to bovine bone, when employed as a model for dental implantology. The use of internal irrigation drilling systems is promoted on the basis of improved delivery of coolant to the bone/drill(More)
OBJECTIVES Changes in bone temperature during the sequence of drilling for implant site preparation using the Branemark technique were monitored using infra-red thermography. METHODS Bovine mandibles were used to provide cortical bone of a similar quality to human mandibular bone. To ensure the consistency in the drilling procedure, one operator used a(More)
The purpose of this study was to ascertain the applicability of infrared thermography to study the natural history of herpes labialis lesions. Since thermography is capable of detecting changes not visible to the naked eye, then it may be of value in complementing clinical examination of the various stages of herpes labialis. In addition, thermographic(More)
AIM To investigate the rewarming pattern and rewarming rate of clinically healthy teeth following a controlled cold stimulus using TI techniques. METHODOLOGY A controlled cold stimulus was developed using an air stream at 20 degrees C. Gingival and incisal sites on 12 healthy maxillary lateral incisors in six patients were imaged under rubber dam(More)
BACKGROUND Orofacial granulomatosis is a clinical entity presenting with chronic swelling of the oral or facial tissues in association with histological evidence of noncaseating granulomatous inflammation. Its cause remains unclear, but a possible role of contact sensitivity to dietary components has been proposed. OBJECTIVES This study was performed to(More)
BACKGROUND The study was designed to determine the efficacy of OraDisc (active component 2 mg amlexanox) on the prevention of aphthous ulcers treated at the prodromal stage. METHODS Thermographic imaging was used to confirm the presence of a prodromal ulcer. Fifty-two patients were randomized to receive OraDisc (N = 26) or vehicle patches (N = 26).(More)
