Extra-Short Implants with Osteotome Sinus Floor Elevation: A Prospective Clinical Study

WOS: 000519127500022PubMed: 32142579Purpose: the aim of this study was to assess the radiographic and clinical outcomes of extra-short implants either alone or in conjunction with osteotome sinus floor elevation and to compare these with regular-sized implants in the posterior atrophic maxilla. Materials and Methods: Systemically healthy, nonsmoker individuals having at least one tooth gap in the posterior maxilla were included in the study. When the residual bone height was .05). Conclusion: Extra-short implants placed either in native bone or in conjunction with osteotome sinus floor elevation may provide similar clinical and radiographic outcomes that are comparable to those obtained with regular implants. Both extra-short implant placement methods can be promising noninvasive treatment options for the posterior maxilla, and implant dimension, crown length, crown-to-implant ratio, and residual bone height may not affect the crestal bone level change, at least in the short term

Coronally advanced flap with connective tissue graft or xenogeneic acellular dermal matrix in the treatment of multiple gingival recessions: A split-mouth randomized clinical trial

nizam, Nejat/0000-0003-2739-3919WOS: 000498259100001PubMed: 31762155Objective To evaluate the clinical efficacy of xenogeneic acellular dermal matrix (XADM) or connective tissue graft (CTG) combined with modified-coronally advanced flap (M-CAF) in the treatment of multiple gingival recessions. Materials and methods Twelve participants with bilateral MGRs (multiple gingival recession) (82 gingival recessions) randomly received XADM (test group, 41 teeth) on one side and subepithelial CTG (control group, 41 teeth) on the other side in conjunction with M-CAF in the same session and completed the 18-months study period. Recession depth (RD), recession width (RW), keratinized tissue width (KTW), probing depth (PD), and clinical attachment level (CAL) were recorded at baseline, and 6-, 18-months postoperatively. Results PD was significantly higher in the test group at 18-months (P .05). Conclusion Within the limits of the study, M-CAF combined with XADM or CTG seems to be similarly effective in RD reduction of class I and II MGRs at least in the short term. Soft tissue shrinkage and increase in PD may be observed with XADM, while; CTG seems to provide stable clinical outcomes for 18-months follow-up. Clinical significance Even though the CTG and XADM in conjunction with M-CAF may provide similar RD reduction in class I and II multiple gingival recessions in the short term. CTGs may be superior in terms of soft tissue shrinkage and PD values

What is the rate of tobacco usage among dental school students?

Introduction This survey aimed to investigate the rate of students in dental schools that use various tobacco products and possible factors affecting their attitudes towards tobacco products. Methods The survey was conducted between May 1 and June 30, 2018 and participants were from ten dental schools in Turkey. First year students and fifth year students were compared in terms of tobacco product usage and their attitudes towards tobacco. Data were tested statistically using Statistical Package for Social Sciences (SPSS) 15.0 program and chi-square test. Results A total of 1228 students from eleven different dental schools completed the online survey. Majority of the participants were females (62.1 %) and males were less (37.9 %). Mean age of the participants was 21.8±2.9 years (min-max; 18-54 years). The overall rate of current smokers was 38.11%, but 56.6% of the participants have inhaled tobacco smoke. More than half (55.3%) of the current smokers stated that they wish to quit and 36.7% of these students have attempted to quit within the last six months. More than 10% of all participants defined themselves as highly addicted to cigarette smoking. The rate of waterpipe smokers were 41.2% and 83.7% of these students were not willing to stop waterpipe smoking. Conclusions The rate of current tobacco smokers is rather high among dental school students and this finding points out the need for more effective precautions against tobacco.
