Rashid","doi":"10.4103/2321-4619.143601","DOIUrl":"https://doi.org/10.4103/2321-4619.143601","url":null,"abstract":"Risk of exposure to blood‑borne pathogens has always been a problem for healthcare professionals including dental professionals. The emergence of acquired immunodeficiency syndrome (AIDS) in 1981 brought the issue to the forefront of public health policy. Percutaneous injuries, which include needle stick injuries (NSI), expose dental healthcare workers to deadly blood‑borne pathogens such as Hepatitis C virus (HCV), Hepatitis B virus (HBV), and Human Immunodeficiency Virus (HIV). The risk of transmission of HCV, HBV, and HIV from patient to the healthcare personnel is 3%, 30%, and 0.3%, respectively. [1,2] Although the likelihood of being infected by a blood‑borne virus (BBV) may be low after a single exposure, the consequences for the dental professional who becomes infected are potentially serious and include the potential of transmission of blood‑borne pathogens and associated detrimental effects on their personal and professional lives. [3] Needles used for injecting local anesthesia during restorative procedures and the use of sharps during endodontic and prosthodontic procedures pose a high risk of transmission of BBVs. Procedures in restorative dentistry that may make the patient to cause a sudden jerky movement can lead to increase probability of NSI. Thus, education and training regarding the use of universal precautions when handling body fluids should be conducted. New employees should go through the training program stressing the need to report all injuries and the availability of chemoprophylaxis. Improving sharps disposal by introducing improved sharps containers in the dental clinics. Sharps should be disposed immediately. Recapping and re‑sheathing should be discouraged and new arrangements for sharps disposal should be done to avoid overfilling boxes. NSI prevention strategies for dental professionals should be implemented in the dental curriculum and during the pre‑occupational/occupational training programs. Since a relatively high percentage of patients are positive for major blood‑borne infections, the risk of exposure to blood‑borne pathogens for healthcare workers through NSI should not be ignored. Regular health checkups, tests for serum antibodies and antigens of HBV, and appropriate hepatitis B vaccination are mandatory for occupational safety of healthcare workers. Report of NSI cases should be encouraged since it is needed for root cause analysis of the adverse events and future prevention. The report of NSI events is also highly important for the injured parties in view of risk assessment and implementation of appropriate prophylactic measures for blood‑borne infections.","PeriodicalId":17076,"journal":{"name":"Journal of Restorative Dentistry","volume":"26 1","pages":"157 - 157"},"PeriodicalIF":0.0,"publicationDate":"2014-09-01","publicationTypes":"Journal Article","fieldsOfStudy":null,"isOpenAccess":false,"openAccessPdf":"","citationCount":null,"resultStr":null,"platform":"Semanticscholar","paperid":"91120254","PeriodicalName":null,"FirstCategoryId":null,"ListUrlMain":null,"RegionNum":0,"RegionCategory":"","ArticlePicture":[],"TitleCN":null,"AbstractTextCN":null,"PMCID":"","EPubDate":null,"PubModel":null,"JCR":null,"JCRName":null,"Score":null,"Total":0}

Materials and Methods: In the present study, 20 caries-free human molar teeth were used. Occlusal surfaces were removed to achieve a uniform dentin surface under water cooling by using a low-speed diamond saw. The dentin surfaces obtained were abraded for one minute by using 600-grit silicon carbide papers. Then, the teeth were randomly assigned into four groups (n = 5). For restoration of teeth prepared, four different one-step self-etching adhesive systems, including Clearfil S 3 Bond Plus, Clearfil S 3 Bond, Xeno V Bond and Adper Easy Bond were used according to manufacturer′s instructions. A 4 mm thick of composite resin crown (ClearfilAP-X) was applied to surfaces pre-treated with bonding agent. Samples were stored in distilled water at 37°C for 24 hours until micro-tensile bond strength tests were performed. Statistical analyses were performed by using one-way ANOVA and post-hoc Tukey tests (α =0.05). Fracture surfaces were evaluated using a stereomicroscope. Results: Significant differences were observed in bond strength to dentin among one-step self-etching adhesive systems (P < 0.05). The highest bond strength was achieved by Clearfil S 3 Bond Plus system (P < 0.05). No significant difference was observed in bond strength among other groups (P > 0.05). Conclusion: There were differences between bond strength values of tested one-step self-etch adhesives. Clearfil S 3 Bond Plus exhibited higher values.","PeriodicalId":17076,"journal":{"name":"Journal of Restorative Dentistry","volume":"5 1","pages":"130 - 135"},"PeriodicalIF":0.0,"publicationDate":"2014-09-01","publicationTypes":"Journal Article","fieldsOfStudy":null,"isOpenAccess":false,"openAccessPdf":"","citationCount":null,"resultStr":null,"platform":"Semanticscholar","paperid":"90305604","PeriodicalName":null,"FirstCategoryId":null,"ListUrlMain":null,"RegionNum":0,"RegionCategory":"","ArticlePicture":[],"TitleCN":null,"AbstractTextCN":null,"PMCID":"","EPubDate":null,"PubModel":null,"JCR":null,"JCRName":null,"Score":null,"Total":0}

However, polymerization shrinkage and the resultant microleakage remain major obstacles in the successful use of these materials. Aims: The aim of this study was to investigate the effects of placement technique on microleakage of Quixfil® composite restorations bonded with Xeno III® bonding agent Settings and Design : In vitro study. Materials and Methods : Thirty-four cylindrical cavities measuring 5 mm in diameter and 3 mm in depth were prepared on the buccal aspect of extracted human teeth. The apices of all the teeth were sealed and the teeth randomly assigned into the bulk and the incremental groups for restoration. Restorations were polished and two layers of nail varnish applied on all tooth surfaces except a rim of 1 mm around the restorations. The teeth were thermo-cycled and stained with 2% methylene blue dye. The restorations were sectioned and examined under light microscopy. Dye penetration on the tooth-restoration interface was scored on an ordinal scale of 0 to 4. Statistical Analysis Used : Pair-wise comparison of the two placement groups was done using the Wilcoxon Signed Ranks Test. Results : No statistically significant difference was observed in the microleakage of the two study groups (P value > 0.05). Conclusions : There is no statistically significant difference in the microleakage of the bulk and the incremental Quixfil restorations. It is feasible to place Quixfil restorations in layers of up to 3 mm in depth.","PeriodicalId":17076,"journal":{"name":"Journal of Restorative Dentistry","volume":"105 1","pages":"136 - 143"},"PeriodicalIF":0.0,"publicationDate":"2014-09-01","publicationTypes":"Journal Article","fieldsOfStudy":null,"isOpenAccess":false,"openAccessPdf":"","citationCount":null,"resultStr":null,"platform":"Semanticscholar","paperid":"85787761","PeriodicalName":null,"FirstCategoryId":null,"ListUrlMain":null,"RegionNum":0,"RegionCategory":"","ArticlePicture":[],"TitleCN":null,"AbstractTextCN":null,"PMCID":"","EPubDate":null,"PubModel":null,"JCR":null,"JCRName":null,"Score":null,"Total":0}

A 42-year-old woman applied to our clinic with complaint of pain on her left mandibular second premolar tooth. Radiologic examination by panoramic radiograph indicated that the teeth had a root canal treatment and there was a radiolucency through the mesial area of the root. This data was considered that there might be a root fracture, which cannot be detected on panoramic radiograph. Thus, the condition was told to the patient and after her permission, it was decided to take a CBCT image for definite diagnosis. The tooth was scheduled for extraction and socket preservation. A new CBCT image was taken from the extracted teeth with much more dosage to observe the fracture line every aspect. Also, the tooth was sent to the histology department for histologic investigation. The CBCT image demonstrated hardly visible VRF at the coronal, mid-root and apical levels in the axial views. Fracture line that extends through the long axis of the tooth was seen obviously on CBCT image which was taken after extraction and histologically with different zoom in (×25, ×40, ×100, ×200, and ×400). Different stages of endodontic treatment may cause VRFs. Symptoms of VRF are often not obvious, because of this diagnosis may be difficult for dentists. CBCT images could be helpful to evaluate VRFs which cannot diagnose.","PeriodicalId":17076,"journal":{"name":"Journal of Restorative Dentistry","volume":"73 1","pages":"154 - 156"},"PeriodicalIF":0.0,"publicationDate":"2014-09-01","publicationTypes":"Journal Article","fieldsOfStudy":null,"isOpenAccess":false,"openAccessPdf":"","citationCount":null,"resultStr":null,"platform":"Semanticscholar","paperid":"85999921","PeriodicalName":null,"FirstCategoryId":null,"ListUrlMain":null,"RegionNum":0,"RegionCategory":"","ArticlePicture":[],"TitleCN":null,"AbstractTextCN":null,"PMCID":"","EPubDate":null,"PubModel":null,"JCR":null,"JCRName":null,"Score":null,"Total":0}

Materials and Methods: Forty extracted human molars were randomly assigned to four groups (n = 10). Teeth in Groups 2-4 received root canal treatment and a MOD cavity preparation. Group 1 served as control. Group 2 was restored with composite resin. In Group 3, the fiber was inserted into the cavities in buccal to lingual direction by coating the occlusal one-third of the buccal wall to the occlusal one-third of the lingual wall, and lastly, the teeth were restored with composite resin. In Group 4, the flowable resin was coated inside the cavities with the fiber, as Group 3 was before restoring teeth with composite resin. Compressive loading of the teeth was performed at a cross-head speed of 0.5 mm/min. Data were analyzed using one-way ANOVA and Tukey post-hoc tests. Results: Fracture resistance values of all the groups were compared; the differences between Groups 2 and 3 or Groups 2 and 4 were found to be statistically significant. Conclusions: As a result, use of the fiber under composite resin with a flowable resin increased fracture strength to MOD cavities.","PeriodicalId":17076,"journal":{"name":"Journal of Restorative Dentistry","volume":"103 1","pages":"144 - 148"},"PeriodicalIF":0.0,"publicationDate":"2014-09-01","publicationTypes":"Journal Article","fieldsOfStudy":null,"isOpenAccess":false,"openAccessPdf":"","citationCount":null,"resultStr":null,"platform":"Semanticscholar","paperid":"78612756","PeriodicalName":null,"FirstCategoryId":null,"ListUrlMain":null,"RegionNum":0,"RegionCategory":"","ArticlePicture":[],"TitleCN":null,"AbstractTextCN":null,"PMCID":"","EPubDate":null,"PubModel":null,"JCR":null,"JCRName":null,"Score":null,"Total":0}

In this kind of injury, root canal treatment is indicated when the signs of pulp necrosis such as spontaneous pain, pain to percussion, periradicular pathosis, inflammatory root resorptions and discoloration are present. In cases of coronal fractures, the treatment strategy differs according to the status of pulp tissue. If the fracture line is limited in enamel or dentin, restoration of the missing tissues can be achieved with composite resin.
