Gingival retraction is the procedure of bending gingival margin away from tooth surface, which provides sufficient horizontal and vertical space between prepared finish line gingiva for introduction a amount impression material. Several factors influence success durability orthopedic restorations in dentistry. In particular, supragingival margins are necessary to maintain periodontal health, bu...

Cordless retraction paste material for gingival retraction in implant dentistry has recently become of interest to the clinician. However, few studies have been conducted on the use of retraction pastes and their possible interaction with implant surfaces. This in vitro study evaluated the effect of a cordless retraction paste material, Expasyl® (Acteon), on TiUnite® (Nobel Biocare) implant sur...

An increased significance on perio–restorative interface in restorative dentistry essential enable utilization concept biologic width practical manner. The goal, regarding management gingival tissues, ensure peridontium healthy state. oral cavity difficult treat because lips...

Control of hemorrhage is one of the challenging situations dentists confront during deep cavity preparation and before impressions or cementation of restorations. For the best bond and least contamination it is necessary to be familiar with the hemostatic agents available on the market and to be able to choose the appropriate one for specific situations. This review tries to introduce the comme...

Objective: to assess the amount of vertical and lateral gingival tissue displacement recovery obtained by aretraction cord Magic Foam® paste. Material Methods: twenty- two participants, requiring full coverageprosthesis in anterior area, were prepared using a deep subgingival chamfer finish line, then randomly allocatedto retraction group (Group RC, n = 11 teeth) or Paste FP, teeth).The was mea...

OBJECTIVE To evaluate the influence of Expasyl® gingival retraction paste on the shear bond strength of self-etch and total-etch adhesive systems. MATERIALS AND METHODS Twenty-four specimens of extracted, caries-free, sound human molars were used in this study. The molars were then cut vertically into halves through the buccal and lingual cusps. Forty-eight specimens were divided into four gr...

Subcutaneous facial emphysema after dental treatment is an uncommon complication caused by the invasion of high-pressure air; in severe cases, it can spread to the neck, mediastinum, and thorax, resulting in cervical emphysema, pneumomediastinum, and pneumothorax. The present case showed subcutaneous cervicofacial emphysema with pneumomediastinum after class V restoration. The patient was fully...
