Minimally invasive use of coloured composite resin in aesthetic restoration of periodontially involved teeth: Case report.

Gingival recession causes not only aesthetic problems, but problems with oral hygiene, plaque accumulation, speech, and tooth sensitivity. Replacing the missing gingival tissue with composite resin, when indicated, can be a time- and cost-effective solution. Here we report the case of a 25-year-old female who presented with generalized gingival recession. Black triangles were present between the maxillary and mandibular anterior teeth due to loss of interdental tissues, caused by recent periodontal surgery. She also had slightly malposed maxillary anterior teeth. The patient elected to replace gingival tissue with pink composite resin and to alter the midline with composite resin veneers. The first treatment phase involved placement of pink gingival composite to restore the appearance of interdental papilla to her upper (16, 15, 14, 13, 12, 11, 21, 22, 23, and 24) and lower (34, 33, 32, 31, 41, 42, 43, and 44) teeth. Phase two was to place direct composite resin bonded veneers on her upper (16, 15, 14, 13, 12, 11, 21, 22, 23, and 24) teeth to alter the midline and achieve desired colour. The third treatment phase was to level the lower incisal edge shape by enameloplasty (31, 32, 41, and 42) to produce a more youthful and attractive smile. This case report and brief review attempt to describe the clinical obstacles and the current treatment options along with a suggested protocol. Use of contemporary materials such as gingival coloured composite to restore lost gingival tissue and improve aesthetics can be a simple and cost-effective way to manage patients affected by generalized aggressive periodontitis (AgP).

An in-vitro comparative study of the retention of grooved and flat endodontic posts in treated root canals using two different types of cements.

This study evaluated and compared the retentive capability of performed cast posts in endodontically treated premolar teeth using the following: 1--smooth versus grooved post design 2--surface treatment of the root canals with either 17% EDTA followed by 2.25% Naocl or using Naocl only. 3--cementation of the posts with either polycarboxylate cement or C & B Metabond. Cast metal posts were made, cemented in root canals and divided into groups representing combinations of variables. The force required for post removal were recorded and statistically analysed. The results indicated that cementation of the grooved cast metal post with polycarboxylate cement after removal of the smear layer was the most retentive system. More over C & B Metabond resin cement with any post design in presence or absence of smear layer gave high retentive values.
