Chemical cleaning methods for prostheses colonized by Candida spp.: A systematic review.

Statement Of Problem: Different chemical agents have been used to clean and decontaminate dentures. However, consensus on their effectiveness and protocol for use is lacking.

Purpose: The purpose of this systematic review was to evaluate chemical cleaning methods used to promote a reduction in or elimination of Candida spp.

Use of modified lip repositioning technique associated with esthetic crown lengthening for treatment of excessive gingival display: A case report of multiple etiologies.

Excessive gingival display during smile can result in compromised esthetics. This study aims to report a case of excessive gingival display with multiple etiologies treated by means of modified lip repositioning technique associated with esthetic crown lengthening. A 23-year-old female patient, with 5-mm gingival display during smile caused by altered passive eruption and hypermobility of the upper lip, underwent the modified lip repositioning technique associated with gingivectomy followed by flap elevation and ostectomy/osteoplasty.

Over-refractory casting technique as an alternative to one-piece multi-unit fixed partial denture frameworks.

Statement Of Problem: Soldering has been suggested to achieve acceptable fit of multi-unit fixed partial denture (FPD) frameworks of 3 or more elements. However, distortion of the entire framework may occur.

Purpose: The purpose of this study was to evaluate marginal fit in 1-piece-casting FPD frameworks comparing 2 casting techniques: the conventional technique (CT) and the over-refractory technique (ORT).
