Tooth shade selection using a colorimetric instrument compared with that using a conventional shade guide.

Objectives: The aim of this study was to compare the colour matching ability of instrumental colorimetry with that of a conventional visual colour matching technique.

Setting: The study was conducted in a dental clinic at the University of Otago, School of Dentistry, New Zealand.

Materials And Methods: Three dentists with normal colour vision used a Vita Classical shade guide to determine the shade of the maxillary right central incisor of 10 randomly chosen individuals.

An evaluation of polymer rotary instruments' ability to remove healthy, non-carious dentine.

The aim of this study was to confirm that Smartprep burs do not cut non-carious, healthy dentine. Twenty non-carious extracted molars were trimmed with a diamond bur to remove enamel and to create a flat dentine surface. A new Smartprep bur (RA # 4) was applied to each tooth for 30 seconds.

Patients' satisfaction with prosthetic devices.

The purpose of the paper was to ascertain the factors which affect the satisfaction of patients with the prosthetic therapy. The purpose of the paper was also to ascertain if there are common factors characteristic for patients dissatisfied with the prosthetic therapy although the specialist appraises it as objectively successful. 52 patients of the Clinical Institute for Rehabilitation and Orthopedic Devices were participating in the research, to which, after unsuccessful surgical-prosthetic rehabilitation, reamputation and prosthetic provision was carried out, which was appraised successful by the doctor.

Distal implants to modify the Kennedy classification of a removable partial denture: a clinical report.

Dental implants or precision attachments can be used to resolve the bilateral distal extension removable partial denture (RPD) dilemma. This report describes the fabrication of a mandibular implant-supported chromium-cobalt RPD with a combination of bilateral single molar implants and metal ceramic crowns using the principles of the channel-shoulder-pin system. The maxillary arch was restored with splinted metal crowns and a conventional RPD retained by extracoronal precision attachments.

Anterior loop of the mental nerve: a morphological and radiographic study.

Treatment planning for dental implant patients is often complicated by the unknown extent of the anterior loop of the mental neurovascular bundle. The aim of this study was to determine the correlation between the visual interpretation of the panoramic radiographs and the anatomical dissection findings in a cadaveric sample. Panoramic radiographs of the 22 randomly selected coronally sectioned human head specimens were taken using the Scanora (Soridex, Orinon Corporation Ltd, Helsinki, Finland) radiographic unit jaw panorama (Programme 001, magnification 1.

Patterns of emergence of the human mental nerve.

This study investigated the path of emergence of the mental nerve in a number of human population groups. Skeletal material comprised 117 Negro skulls (53 males), 114 caucasoid skulls (62 males) and 100 pre-contact Maori skulls (70 males). In each case, the path of emergence was classified into posterior, anterior, right-angled or multiple.
