This article represents microsurgical treatment of a three-rooted mandibular first molar with a separate DL root. The procedure includes incision and flap retraction, osteotomy, apicoectomy, retropreparation and retrofilling of the root canal, using micro instruments, ultrasonic retrotips and mineral trioxide aggregate (MTA) under a dental operating microscope. Two mm in length of apical root resection, 2 mm in depth of root canal retropreparation with a personalised ultrasonic retrotip, and 2 mm in length of retrofilling with MTA are the key points for accomplishment of apical surgery on separate DL roots. The case was followed up for 15 months after surgery. Clinical and radiographic examinations revealed complete healing of periapical tissue. Separate DL roots of three-rooted mandibular first molars can be treated by endodontic microsurgery with modifications from standard protocol.","PeriodicalId":22405,"journal":{"name":"The Chinese journal of dental research : the official journal of the Scientific Section of the Chinese Stomatological Association","volume":"17 1","pages":"171-4"},"PeriodicalIF":0.0,"publicationDate":"2016-01-01","publicationTypes":"Journal Article","fieldsOfStudy":null,"isOpenAccess":false,"openAccessPdf":"","citationCount":null,"resultStr":null,"platform":"Semanticscholar","paperid":"90712645","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}

METHODS Melamine sponge of thickness 40 mm was compressed and the destruction of the partition wall structure during the compression process was examined under a stereoscopic microscope. An extracted human tooth was cleaned by normal polishing or with melamine sponge for 90 s. To evaluate the stain level, the tooth surfaces were photographed under a stereoscopic microscope at 0, 30, 60 and 90 s. The residual stained region was traced in a high-magnification photograph, and the stain intensity was presented as a change, relative to the intensity before the experiment (0 s). RESULTS Mechanical cleaning by toothbrushing produced polishing scratches on the tooth surface, whereas use of the melamine sponge resulted in only minimal scratches. As the compression level increased, the stain-removing effect tended to become stronger. CONCLUSION Melamine sponge can remove stains from the tooth surface more effectively and less invasively compared to a conventional toothbrush. As no new scratches are made on the tooth surface when using a melamine sponge brush, the risk of re-staining is reduced. Cleaning using a melamine sponge brush can be easily and effectively performed at home and in a dental office.","PeriodicalId":22405,"journal":{"name":"The Chinese journal of dental research : the official journal of the Scientific Section of the Chinese Stomatological Association","volume":"58 1","pages":"235-40"},"PeriodicalIF":0.0,"publicationDate":"2015-01-01","publicationTypes":"Journal Article","fieldsOfStudy":null,"isOpenAccess":false,"openAccessPdf":"","citationCount":null,"resultStr":null,"platform":"Semanticscholar","paperid":"85443337","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 successful surgical procedure is determined by a number of factors. It is reported that different techniques for sinus augmentation have a high percentage of success, but presents a number of intraoperative and postoperative complications such as the Schneiderian membrane perforation and a long operating time. To manage the problem of the insufficient bone height in the posterior maxilla, various bonegrafting materials were applied using different techniques and instruments to elevate the sinus membrane and fill the subsinus cavity thereafter. The article aimed to describe a minimally invasive technique, using a special design bur to wear out the lateral bone safely and elevate the sinus membrane with sophisticated separators. Platelet-rich fibrin (PRF) and decalcified bone allograft was used as grafting material to enhance bone healing. This new technique for the sinus lateral wall osteotomy minimised the incidence of intraoperative and postoperative complications and the mixed use of PRF with decalcified bone allograft showing a satisficatory efficacy.","PeriodicalId":22405,"journal":{"name":"The Chinese journal of dental research : the official journal of the Scientific Section of the Chinese Stomatological Association","volume":"350 1","pages":"241-5"},"PeriodicalIF":0.0,"publicationDate":"2015-01-01","publicationTypes":"Journal Article","fieldsOfStudy":null,"isOpenAccess":false,"openAccessPdf":"","citationCount":null,"resultStr":null,"platform":"Semanticscholar","paperid":"77478084","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}

METHODS Five teeth in four patients were included in this study. Each tooth had buccal and/ or lingual bone loss identified by bone sounding and periapical radiographs before removal. After a flapless, minimally invasive tooth extraction, the socket was grafted with deproteinized bovine bone mineral with or without a collagen membrane. At the buccal and/or lingual bone defect area, the buccal and/or lingual gingival walls may act as holders, to support the materials. Finally, colloidal silver gelatin sponge was packed gently on top of the graft or membrane to avoid graft or membrane exposure, without attempting to achieve primary closure of the soft tissue. Six months after augmentation, changes in ridge width, ridge height and keratinised tissue were measured on clinical photographs or radiographs. RESULTS The alveolar bone widths observed at implant surgery were all greater than 6 mm. All patients showed bone augmentation in terms of ridge height. Keratinised tissue width showed increased or minor reductions. CONCLUSION Treated with this technique, the deficient socket was re-established in the molar area. Clinically, the quantity and quality of the bone obtained in the grafted sockets allowed for successful implant placement.","PeriodicalId":22405,"journal":{"name":"The Chinese journal of dental research : the official journal of the Scientific Section of the Chinese Stomatological Association","volume":"83 1","pages":"221-8"},"PeriodicalIF":0.0,"publicationDate":"2015-01-01","publicationTypes":"Journal Article","fieldsOfStudy":null,"isOpenAccess":false,"openAccessPdf":"","citationCount":null,"resultStr":null,"platform":"Semanticscholar","paperid":"85779814","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}

Retention of composite resin restoration mainly relies on bonding strength between the materials and dental tissue. The clinical outcomes rely greatly on the regulated clinical practice of dentists. In 2011, the Society of Cariology and Endodontology of Chinese Stomatological Association (CSA) published the 'Practices and evaluation criteria of composite resin bonded restoration (Discussion Version)'. Since then, opinions and comments regarding the 'Discussion Version' have been widely circulated within the Society. The final version of the guideline was based on systematic reviews of scientific literature and requirements for the edit of technical guidelines, and through several rounds of discussions, revisions and supplements.

For each cast condition, 24 disk shaped specimens were fabricated (5 mm in diameter, 0.5 mm in thickness). All the recasting was performed without adding new alloy. After the first cast and following each recast, the surface composition and microstructure of the alloy were determined using an X-ray fluorescence spectrometer and optical microscope, respectively. The in vitro cytotoxicity and in vivo mucous irritation potential of the cast and recast Ni-Cr alloy were investigated. The results were statistically analysed at the significance level of 0.05.\u0000\u0000\u0000RESULTS\u0000Recasting neither yielded to cytotoxicity or to changes in the surface composition of the Ni-Cr alloy tested. However, an increase in impurities and porosity of the surface structure was observed with recasting. Also, the segregation of the impurities to grain boundaries was evident after multiple castings. After the fourth recast, the alloys showed significantly greater mucosal irritation than the control.\u0000\u0000\u0000CONCLUSION\u0000After fourth recast, the alloy of this type may contribute to mucosal inflammation.
