Assessment of facial self-image by means of a distorting mirror and its relationship to personality.

A flexible distorting mirror was used to give a distorted image of volunteers, who then attempted to alter the mirror to give a true reflection of their faces. Their accuracy in performing this task was correlated with age, sex, extroversion, neuroticism and also with total body and facial self-image as obtained from questionnaires. On average, subjects could not accurately define the size of their faces to within 5 cm, and the higher the body image score on the questionnaire, the less well subjects performed on the flexible mirror.

Studies in tooth crown temperature gradients with the use of infrared thermography.

With the use of an infrared thermographic camera; temperature patterns over the crowns of teeth were recorded. The temperature of upper incisor teeth decreased from gingival margin to incisal edge by approximately 2.5 degrees C. Vital and nonvital teeth were the same temperature at rest, but after cooling with cold air, nonvital teeth were slower to rewarm than vital teeth. The infrared thermographic camera could provide a method of testing tooth vitality based on blood supply rather than nerve supply.

Infrared thermography in oral and maxillofacial surgery.

A highly sensitive infrared thermographic camera was evaluated in a variety of physiologic and pathologic conditions associated with the head and neck. Although it may have clinical applications, particularly in the field of facial pain and the temporomandibular joint, such wide variations in normal values were noted that any standardization was extremely difficult.

The marginal mandibulectomy for the treatment of mandibular tumours.

With the knowledge and techniques gained from orthognathic surgery and more precise imaging techniques, it has become more practical to carry out rim or marginal resections for some malignant tumours of the alveolus to preserve mandibular continuity and yet have adequate tumour margins. This is of great functional and cosmetic importance to the patient. A study of 11 patients is presented to analyse criteria for carrying out this procedure.

Central giant cell granulomas of the jaws. Nuclear DNA analysis using image cytometry.

Giant cell nuclear DNA, in 30 giant cell lesions of the jaws, was quantified by computer-assisted image analysis. DNA content was then used to predict clinical behavior and outcome. 4 nuclei in each of 25 giant cells (total = 100 nuclei) were randomly selected and the DNA content was quantified by the Leitz Texture-Analysis-System-Plus. DNA in nuclei of normal appearing stromal fibroblasts (n = 20) was similarly measured. The DNA index was calculated as the mean nuclear DNA content of giant cells divided by the mean DNA content of control fibroblasts. The mean DNA-index of aggressive lesions (1.09, SD = 0.12) was not significantly different from that of non-aggressive lesions (1.18, SD = 0.15) (p = 0.093). The results indicate that the nuclear DNA content of giant cells is not useful as a predictor of the clinical behavior of giant cell lesions of the jaws.

Liquid crystal thermography as a diagnostic aid and objective monitor for TMJ dysfunction and myogenic facial pain.

Liquid crystal contact thermography was used to assess both normal control patients and patients with temporomandibular joint and myofascial pain. The technique appears capable of detecting temperature changes around the TMJ and muscles of mastication. Patients with painful internal derangements of the TMJ have warm areas over the joint, and those with myogenic facial pain symptoms have areas of variable temperature over the masseter muscle. After successful nonsurgical treatment of these conditions, the thermograms return to normal.

Intraoral findings in patients with psoriasis with a special reference to ectopic geographic tongue (erythema circinata).

One hundred patients with a severe relapse of cutaneous psoriasis underwent a full intraoral examination. Nineteen patients had "ectopic geographic tongue" of the palate or buccal mucosa, and there appeared to be an increased incidence of periodontal disease. All other findings were within the normal range. HLA antigen studies of eight patients were carried out and showed an increased incidence of DR7.

The lower border rib graft for mandibular atrophy.

Eight patients treated by a modified lower border rib grafting technique for severe mandibular atrophy have been followed for between two and eight years. The clinical results have been very satisfactory and resorption has been less than 12% after two years.

Arteriographic assessment of patency of the inferior alveolar artery and its relevance to alveolar atrophy.

Patency of the inferior alveolar artery was investigated on 84 patients who had undergone selective external carotid angiography with digital subtraction. Patency of the artery was lost earlier in males than females, but the presence or absence of teeth did not appear to affect the outcome. The artery was visualized less well on patients with medical conditions that may predispose to early or excessive atherosclerotic disease.

Articular eminectomy for recurrent dislocation.

Articular eminectomy was carried out on 15 patients for correction of recurrent temporomandibular joint dislocation. The operation was successful in all cases in that recurrent dislocation was prevented. The success, however, seemed to occur because of restriction of condylar motion on the affected side, rather than by allowing greater freedom. The main complication of the surgery was transient paresis of the associated branches of the facial nerves.
