The aim of this study was to evaluate the efficacy of double-application of PRP (DA-PRP) on bone healing in rabbit cranial defects by examining osteonectin (ON) and osteocalcin (OC) expression.Materials and methods: Twenty-eight rabbits, each with two surgically prepared calvarial bone defects, were included in this study and divided into six groups: The defects (N=56) were treated with either a single-application of PRP (SA-PRP) (n=10), a combination of SA-PRP and betatricalciumphosphate (SA-PRP+β-TCP) (n=10), only DAPRP (n=8), both DA-PRP and beta-tricalciumphosphate (DA-PRP+β-TCP) (n=8), only beta-tricalciumphosphate (β-TCP) (n=10), or controls (n=10). The animals were sacrificed at 30th day postoperatively and samples were immunohistochemically examined for ON and OC expressions.Results: It was determined that DA-PRP did not significantly improve the ON and OC percentages achieved by SA-PRP or the controls. The three groups treated with β-TCP showed a higher percentage of ON than those treated without β-TCP (p<0.05). The β-TCP treated groups and SA-PRP group demonstrated higher OC percentage than DA-PRP and control groups (p<0.05).Conclusion: The present findings suggest that DAPRP did not have a significant effect on the healing of non-critical size rabbit cranial bone defects.","PeriodicalId":30947,"journal":{"name":"Journal of Istanbul University Faculty of Dentistry","volume":"50 2","pages":"1-9"},"PeriodicalIF":0.0,"publicationDate":"2016-04-01","publicationTypes":"Journal Article","fieldsOfStudy":null,"isOpenAccess":false,"openAccessPdf":"https://ftp.ncbi.nlm.nih.gov/pub/pmc/oa_pdf/86/85/jiufd-050-001-b.PMC5573525.pdf","citationCount":null,"resultStr":null,"platform":"Semanticscholar","paperid":"35452323","PeriodicalName":null,"FirstCategoryId":null,"ListUrlMain":null,"RegionNum":0,"RegionCategory":"","ArticlePicture":[],"TitleCN":null,"AbstractTextCN":null,"PMCID":"OA","EPubDate":null,"PubModel":null,"JCR":null,"JCRName":null,"Score":null,"Total":0}

Root canals of the teeth were instrumented and filled before being randomly assigned to three groups. Guttapercha was removed using the Reciproc system, the Twisted File system (TF), and Hedström-files (H-file). Apically extruded debris was collected and dried in pre-weighed Eppendorf tubes. The amount of extruded debris was assessed with an electronic balance. Data were statistically analyzed using one-way ANOVA, Kruskal-Wallis, and Mann-Whitney U tests.Results: The Reciproc and TF systems extruded significantly less debris than the H-file (p<0.05). However, no significant difference was found between the Reciproc and TF systems.Conclusion: All tested file systems caused apical extrusion of debris. Both the rotary file (TF) and the reciprocating single-file (Reciproc) systems were associated with less apical extrusion compared with the H-file.","PeriodicalId":30947,"journal":{"name":"Journal of Istanbul University Faculty of Dentistry","volume":"50 2","pages":"31-37"},"PeriodicalIF":0.0,"publicationDate":"2016-04-01","publicationTypes":"Journal Article","fieldsOfStudy":null,"isOpenAccess":false,"openAccessPdf":"https://sci-hub-pdf.com/10.17096/jiufd.96734","citationCount":null,"resultStr":null,"platform":"Semanticscholar","paperid":"35452327","PeriodicalName":null,"FirstCategoryId":null,"ListUrlMain":null,"RegionNum":0,"RegionCategory":"","ArticlePicture":[],"TitleCN":null,"AbstractTextCN":null,"PMCID":"OA","EPubDate":null,"PubModel":null,"JCR":null,"JCRName":null,"Score":null,"Total":0}

The periapical status of all teeth (with the exception of third molars) was examined using periapical index scoring system (PAI).

Out of 6196 examined teeth, the frequencies of apical periodontitis and endodontic treatment was 1.8% and 3.7%, respectively. Gender had no effect on the presence of apical periodontitis or the frequency of endodontic treatment.

Group 1 was the control group in which no laser application was performed prior to the shear bond strength (SBS) testing. In Group 2, Er:YAG was applied in 3W power for 6 seconds using the scanning method. The brackets were tested for SBS with an Instron universal testing machine and results were expressed in megapascals (MPa). The amount of adhesive remnant was evaluated with Adhesive Remnant Index (ARI). One-way analysis of variance and Tukey's post-hoc tests were used for statistical analysis.Results: Mean ± standard deviation of SBS values in the control group was 13.42 ±1.23 MPa and 8.47 ±0.71 MPa in the Er:YAG group and this difference was statistically significant (p<0.05). The evaluation of ARI scores demonstrated more adhesive was left on the enamel surface with Er:YAG group.Conclusion: 3W power Er:YAG laser application with the scanning method to polycrystalline ceramic brackets demonstrated lower bond strengths and higher ARI scores during the debonding procedure.","PeriodicalId":30947,"journal":{"name":"Journal of Istanbul University Faculty of Dentistry","volume":"50 2","pages":"24-30"},"PeriodicalIF":0.0,"publicationDate":"2016-04-01","publicationTypes":"Journal Article","fieldsOfStudy":null,"isOpenAccess":false,"openAccessPdf":"https://sci-hub-pdf.com/10.17096/jiufd.39114","citationCount":null,"resultStr":null,"platform":"Semanticscholar","paperid":"35452326","PeriodicalName":null,"FirstCategoryId":null,"ListUrlMain":null,"RegionNum":0,"RegionCategory":"","ArticlePicture":[],"TitleCN":null,"AbstractTextCN":null,"PMCID":"OA","EPubDate":null,"PubModel":null,"JCR":null,"JCRName":null,"Score":null,"Total":0}
