Subepithelial connective tissue graft with or without enamel matrix derivative for the treatment of Miller class I and II gingival recessions: a controlled randomized clinical trial

Background The aim of this study was to evaluate whether the combination of enamel matrix derivative (EMD) with subepithelial connective tissue graft (SCTG) plus coronally advanced flap (CAF) would improve the treatment outcomes of Miller class I and II gingival recessions when compared with the same technique (SCTG plus CAF) alone. Methods The study was designed as a randomized, parallel, controlled, double-blinded clinical trial. Forty-two patients were randomly assigned in the test group (SCTG plus EMD) and in the control group (SCTG). Patients had at least one gingival recession ≥ 2 mm. The clinical parameters were evaluated at baseline and at 14 d, 1, 3, 6 and 12 mo follow-up time poin…

Changes in anatomic position of root canal orifices in pluriradicular teeth following re-location during endodontic treatment

Abstract Direct access to the root canals in posterior teeth for endodontic treatment is most frequently facilitated by the straightening of the coronal parts of the root canals, having as a consequence the relocation of the canal orifices on the map of the floor of the pulp chamber ( Christie and Thompson, 1994 ). This procedure intentionally moves the coronal aspect of a canal away from the center of the chamber, while simultaneously removing internal dentin from the pulp chamber walls. The aim of this study was to evaluate the displacement resulting from the relocation of root canal orifices during the initial phase of rotary root canal treatment in molars using the dental operating micr…

The impact of some behavioral aspects on periodontal disease in a group of Romanian students - an epidemiological survey.

Abstract Aims To investigate the prevalence of periodontitis in a young population representative for the North-western part of Romania (Transylvania) and to identify possible risk indicators of periodontitis. Methods The study is a cross-sectional epidemiological survey. The subjects were students randomly sampled from three universities in Cluj-Napoca and high school students from the neighboring city of Bistrita. The sample size of the population was calculated. Overall, 623 subjects aged 16–35 years were evaluated, of which 488 were university students and 135 high school students. A structured questionnaire was administrated to collect information on socio-behavioral status and oral hy…

In vitro and in vivo characterization of porcine acellular dermal matrix for gingival augmentation procedures

Recently, porcine acellular dermal matrix (PADM) has been proposed as a possible alternative to autogenous grafts in periodontal plastic surgery. The aim of the present study was to investigate the in vitro responses of four different oral cell lines cultured on a novel PADM. Furthermore, tissue reaction to PADM was evaluated histologically after subcutaneous implantation in mice.Human gingival fibroblasts (HGF), human osteoblast-like cells, human umbilical vein endothelial cells and human oral keratinocytes (HOK) were cultured and transferred on to the PADM. A tissue culture polystyrene surface served as the control. The viability of all tested cell lines on PADM was measured by using the …
