Materials and methods: Twenty-eight patients participated in this prospective clinical study. After tooth/implant extraction, labial bone defects were grafted with xenogenic bone substitute and covered with a collagen membrane. An implant was placed eight months after the reconstruction surgery and loaded three months later. An evaluation of the hard and soft tissues was performed after a mean of 3 years of follow-up. Cone-beam computed tomography was performed to examine the stability over time and measure the thickness of the reconstructed buccal bone plate. The Pink Aesthetic Score was used to evaluate the aesthetic outcome of the peri-implant soft tissues. Patient satisfaction with aesthetics was also evaluated with a questionnaire 15 months after loading the implant. Results and conclusions: All patients attended the follow-up examination. At the follow-up examination, the mean of the reconstructed facial bone thickness was greater than 2 mm. Based on the examinations using the Pink Aesthetic Score, 10.7% of the cases had a good outcome (> 9 and < 12), and twenty-five out of 28 (89.3%) had a perfect result (> 12). Eleven patients out of 28 indicated good satisfaction, and 17 indicated excellent satisfaction fifteen months after the implant loading. *Correspondence to: Marzio Todisco, via Agello 68/c Desenzano del Garda 25015 Italy, Tel: 39-030-990-1158, E-mail: marzio@marziotodisco.com","PeriodicalId":321276,"journal":{"name":"Journal of Dental Research and Reports","volume":"114 1","pages":"0"},"PeriodicalIF":0.0,"publicationDate":"1900-01-01","publicationTypes":"Journal Article","fieldsOfStudy":null,"isOpenAccess":false,"openAccessPdf":"","citationCount":null,"resultStr":null,"platform":"Semanticscholar","paperid":"117258755","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 cone-beam computed tomography (CBCT) scan showed an impressive lesion with great bone destruction, in direct contact with the inferior alveolar nerve, compressing it. Besides a complete medical history, a CBCT scan may be crucial to identify the cause of the paresthesia, supporting the clinical exam and preventing an irreversible nerve injury.","PeriodicalId":321276,"journal":{"name":"Journal of Dental Research and Reports","volume":"51 1","pages":"0"},"PeriodicalIF":0.0,"publicationDate":"1900-01-01","publicationTypes":"Journal Article","fieldsOfStudy":null,"isOpenAccess":false,"openAccessPdf":"","citationCount":null,"resultStr":null,"platform":"Semanticscholar","paperid":"125063423","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 sample of 50 patients determined by inclusion and exclusion criteria were randomly selected from an initial sample of 200 patients. The pre and posttreatment maxillary and mandibular arch stereolithography (STL) files taken from the iTero digital scans were imported into computer software for measurement. Point to point millimetric measurement of crowding or spacing was measured from the distal of one maxillary or mandibular lateral incisor to the distal of the opposite lateral incisor on the pre and posttreatment models. Lastly, the subjective measure of patient satisfaction was tabulated for each patient. General linear models found treatment effectiveness to achieve statistical significance in the multivariate tests conducted. There was no statistically significant difference between treatment supervised by general practitioners versus orthodontic specialists. Lastly, Fisher’s exact test determined that there was no significant association between satisfaction and who the respondent was treated by. *Correspondence to: Marc B Ackerman, American Teledentistry Association, 9 Roberts Road, Wellesley Hills, MA, USA, Tel: 1-781-304-4409; E-mail: admin@americanteledentistry.org","PeriodicalId":321276,"journal":{"name":"Journal of Dental Research and Reports","volume":"52 1","pages":"0"},"PeriodicalIF":0.0,"publicationDate":"1900-01-01","publicationTypes":"Journal Article","fieldsOfStudy":null,"isOpenAccess":false,"openAccessPdf":"","citationCount":null,"resultStr":null,"platform":"Semanticscholar","paperid":"125871528","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}

The purpose of this case report is to present clinical and radiographic findings of a regenerative endodontic procedure that utilizes MTAD for single-visit disinfection of a tooth with necrotic pulp and open apex with 4-year follow-up. A maxillary central incisor of a 7-year-old girl was avulsed and replanted. The tooth developed pulpal necrosis and symptomatic apical periodontitis. After access preparation into the empty chamber, the canal was irrigated with 5.25% NaOCl followed by BioPure MTAD (Dentsply, Tulsa Dental Specialties, Tulsa, OK). Intracanal bleeding was stimulated. 3 mm of Mineral Trioxide Aggregate (MTA) was placed directly over the clot and access was permanently restored with composite. Clinical examination at 1 year and 6 months showed a closed apex with no sensitivity to percussion or palpation. After 4 years, the tooth was asymptomatic and responsive to both cold and electric pulp testing. Potential differences in angulation between preoperative and recall images were corrected with a geometrical imaging program, NIH ImageJ with TurboReg plug-in. The present case demonstrates REP of a tooth with necrotic pulp and open apex in a single visit with MTAD disinfection. *Correspondence to: Rita Hung, Department of Endodontics, School of Dentistry, Loma Linda University, USA, E-mail: drhungendo@gmail.com Received: January 12, 2019; Accepted: January 21, 2019; Published: January 25, 2019 Introduction Pulpal status and degree of root development are major factors in treatment planning for teeth requiring vital pulp treatment or root canal treatment [1]. Vital pulp treatment can be performed on teeth with open and closed apices. Permanent teeth with closed apices are routinely endodontically treated with a high rate of long-term success [2]. However, teeth with immature and often divergent apices are not suitable for routine endodontic techniques due to large diameter apical foramens and thin dentinal walls susceptible to root fracture [3]. Onevisit or two-visit mineral trioxide aggregate (MTA) apexification is currently used in teeth with necrotic pulps and open apices [3] with a high success rate [4]. However, this procedure addresses only technical issues involved in treatment of these teeth and does not completely eliminate the chance for root fracture [5]. There is a growing body of evidence suggesting the possibility of bringing vital tissues into the pulp space of teeth with necrotic pulps and open apices, along with continued growth of the root and thickening of the root canals walls [6]. Hargreaves et al. [3] identified three components necessary for the success of this procedure: stem cells, signaling molecules and a three-dimensional physical scaffold that can support cell growth and differentiation. Regenerative endodontic procedures are only possible when the root canal space is completely disinfected, and a mi","PeriodicalId":321276,"journal":{"name":"Journal of Dental Research and Reports","volume":"243 1","pages":"0"},"PeriodicalIF":0.0,"publicationDate":"1900-01-01","publicationTypes":"Journal Article","fieldsOfStudy":null,"isOpenAccess":false,"openAccessPdf":"","citationCount":null,"resultStr":null,"platform":"Semanticscholar","paperid":"124529675","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 the DI teeth, a number of cracks and fractures were observed not only in the dentin but in the enamel, and irregular dentinal tubules were remarkable in the internal area of the mantle dentin layer. The circumpulpal dentin of DI teeth was significantly different from that of the control teeth. Results of Raman analysis showed that quantitative differences in the mineral content (carbonate and phosphate) between DI teeth and the control were not significant. However, the amount of matrix (amide I of collagen) was decreased in DI teeth. The DI teeth were found to have increased fragility in both dentin and enamel, it might be due to decreased type I collagen formation. *Correspondence to: Yoko Kamasaki, Department of Paediatric Dentistry, Nagasaki University Graduate School of Biomedical Science, 1-7-1 Sakamoto, Nagasaki 852-8588, Japan, Tel: +81-95-819-7675; Fax: +81-95-819-7675; E-mail: ichiro@nagasaki-u.ac.jp","PeriodicalId":321276,"journal":{"name":"Journal of Dental Research and Reports","volume":"207 ","pages":"0"},"PeriodicalIF":0.0,"publicationDate":"1900-01-01","publicationTypes":"Journal Article","fieldsOfStudy":null,"isOpenAccess":false,"openAccessPdf":"","citationCount":null,"resultStr":null,"platform":"Semanticscholar","paperid":"113999257","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}
