Review of periodontal considerations and surgical retraction techniques for operative dentistry.

Gingival margins of restorations should generally be placed supragingivally or at the gingival crest; however, some valid parameters exist for the extension of margins into the gingival crevice. The successful restoration of teeth in subgingival locations requires familiarity with periodontal anatomy. This paper reviews periodontal considerations, then presents several surgical techniques that facilitate access and improve the periodontal prognosis of teeth that have been compromised through fracture, caries, prior restorative treatment, or habit.

Operative dentistry: an alternative to orthodontics.

The purpose of this paper is to describe a clinical case, which highlights the role of Operative Dentistry in the treatment of Dento-alveolar Disproportion in an impoverished tropical environment. The patient had a diastema located between tooth 24 and tooth 25 due to an atypical position of his tongue while swallowing. The patient had been referred to because he could not afford Orthodontics. We suggested a conservative bridge compounded of 2 resin veneers and pontic bounded by the composite tetric ceram. The 0.5 mm teeth reduction concern lingual and proximal faces with retention form, starting at 0.3 mm from the incisal edge to 0.5 mm from the gingiva was performed with diamond burs (Shoulder and finishing). The result was satisfactory and leads us to conclude that Operative Dentistry is a good alternative to Orthodontics in a very specific social context.

Action research in the professional development of university staff: a case study from operative dentistry.

Action research has long been used in educational research and increasingly features in the professional development of university staff. A brief review of the historical development of action research is presented together with the range of approaches covered and their common characteristics. To illustrate the elements of action research, an example is drawn from operative dentistry. The steps taken by a lecturer to improve a pre-clinical course in operative dentistry are described in some detail and the outcomes of the action are reported and evaluated. The findings support the suitability of action research for professional development in dental education. The kinds of problems likely to be encountered by teachers using this methodology are reported. The ability of the participant investigators to reflect critically on the action taken was found to be a key component of action research.
