Its main function is the regulation of the circadian rhythm (day–night cycles). It plays an anti-inflammatory, antioncotic, and immunomodulatory role by scavenging free-radicals and through interactions with cell membrane and intracellular proteins. Melatonin is capable of entering the oral cavity by diffusing into the saliva from blood. As the majority of the melatonin remains bound to serum albumin, the amount of melatonin in saliva is approximately one-third of that present in the blood. The existence of MT1 receptors on healthy and cancerous oral mucosal cells is suggestive that melatonin may act as an anti-inflammatory or antioncotic agent in the oral cavity; for example, its anti-inflammatory effects have been reported on human gingival fibroblasts. Furthermore, intraperitoneal melatonin has been reported to reduce periodontitis in diabetic rats. Similarly, topical application of melatonin in diabetic patients has diminished the progression of periodontal bone loss as evident by the downregulation of pro-inflammatory factors. Hence, it has been suggested that melatonin may be used in the management of perimucositis and peri-implantitis in the field of dental implants. The aim of this review is to critically analyze and summarize the research focusing on the potential of melatonin in the fields of oral implantology.","PeriodicalId":212982,"journal":{"name":"Journal of Dental Implants","volume":null,"pages":null},"PeriodicalIF":0.0,"publicationDate":"2019-07-01","publicationTypes":"Journal Article","fieldsOfStudy":null,"isOpenAccess":false,"openAccessPdf":"","citationCount":null,"resultStr":null,"platform":"Semanticscholar","paperid":"114038369","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}

This study aims to evaluate the current level of knowledge and attitude of Nigerian general dental practitioners toward the immediate loading protocol of dental implants. Materials and Methods: This is a descriptive, cross-sectional survey conducted among Nigerian dental practitioners. Self-administered, pretested questionnaires were used to collect data regarding their knowledge and attitude to immediate loading of implants. Data collected were analyzed using the Statistical Package for the Social Sciences version 22 (IBM Corp, Armonk, NY, USA) Results: A total of 237 dentists completely filled the questionnaires. Nearly 46% of the participants had good knowledge on the procedure and advantages offered by the immediately loading dental implants with provisional restorations, whereas 81% had negative reservations toward implant placement using the protocol. In addition, this study found a statistically significant association (P < 0.05) between the knowledge and attitude of the dental practitioners regarding the protocol. Conclusion: There is slighlty poor knowledge and significant negative attitude of dentists toward the immediate implant loading protocol in Nigeria. Improved information dissemination from general dental practitioners to patients, and practice of the protocol in indicated cases by implantologists is expected with increased awareness and subsequent training on its use and viability.","PeriodicalId":212982,"journal":{"name":"Journal of Dental Implants","volume":null,"pages":null},"PeriodicalIF":0.0,"publicationDate":"2019-07-01","publicationTypes":"Journal Article","fieldsOfStudy":null,"isOpenAccess":false,"openAccessPdf":"","citationCount":null,"resultStr":null,"platform":"Semanticscholar","paperid":"129014549","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}

Aims: The purpose of this study was to radiographically evaluate the bone formation around the dental implants which were placed at different depths into the maxillary sinus by intentional perforation of maxillary sinus floor during implant placement and its effect on implant survival rate. Settings and Design: A total of 86 implants of varying dimensions were placed in maxillary premolar and molar region by intentional perforation of the maxillary sinus floor during implant placement in 57 patients. Subjects and Methods: They were divided into three groups G1, G2, and G3 based on the depth of penetration into the maxillary sinus (region by [IS] compartment) (IS-G1-1 mm; G2-2 mm; G3-3 mm). The following parameters were evaluated-torque, bone density, and bone fill after 6 months of implant placement. Statistical Analysis Used: The comparison among groups for repeated measures data was made by ANOVA repeated measures test. The correlation between two parameters, i.e., torque and bone fill was done by Karl Pearson's correlation test Results: No significant differences were observed among the three groups for torque, bone fill, and bone density from baseline to 6 months. The correlation between torque and bone fill revealed R = 0.198, P = 0.293 which was statistically insignificant Conclusions: There were minimal failure rates and complications observed at the end of the study period. The survival rate of implants was not influenced either by torque or by the depth of penetration of implant into the maxillary sinus.","PeriodicalId":212982,"journal":{"name":"Journal of Dental Implants","volume":null,"pages":null},"PeriodicalIF":0.0,"publicationDate":"2019-07-01","publicationTypes":"Journal Article","fieldsOfStudy":null,"isOpenAccess":false,"openAccessPdf":"","citationCount":null,"resultStr":null,"platform":"Semanticscholar","paperid":"121520331","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}

Different levels of gingival display, along with the uncertainty of soft- and hard-tissue changes postextraction make things highly predictable in this part of the alveolar ridges. This difficulty is augmented by the patient's desire to have teeth in this esthetic zone immediately. Researchers have devised certain techniques to address this issue and one such method of an immediate, highly esthetic rehabilitation is called the socket shield technique (SST). The use of cortical engagement in this region along with SST gives the operator an opportunity to immediately load the prosthesis with optimal esthetic outcomes. Another challenging issue secondary to implant therapy is peri-implant infections, including the more common peri-implantitis. The presence of rough implant surfaces, when exposed to the oral environment, leads to the formation of a kind of nidus, which, further, feeds soft- and hard-tissue loss. The presence of a periapical pathology from previous dentition may also infect the implant surface. An attempt was made in this case to utilize the SST along with the provision of smooth-surfaced dental implants, stabilized with cortical engagement, for the replacement of missing maxillary anterior teeth.","PeriodicalId":212982,"journal":{"name":"Journal of Dental Implants","volume":null,"pages":null},"PeriodicalIF":0.0,"publicationDate":"2019-07-01","publicationTypes":"Journal Article","fieldsOfStudy":null,"isOpenAccess":false,"openAccessPdf":"","citationCount":null,"resultStr":null,"platform":"Semanticscholar","paperid":"115326144","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: Fourteen completely edentulous patients with age ranged from 47 to 65 years planned to receive conventional complete denture. Following the treatment protocol, each patient received two implants in the mandibular anterior region, and after insurance of the osseointegration, the patients were randomly divided into two groups – Group A received Ball/O-Ring attachment and Group B received locator attachment. The retention of two groups was assessed by the digital force meter at three times (T): T0 – retention of conventional complete denture, T1 – at time of insertion of implant-retained mandibular overdenture, and T3 – retention after 3 months of insertion of implant-retained mandibular overdenture. The implant stability quotient (ISQ) was done using Magnetic Resonance Frequency Analyzer (Osstell, ISQ) at the time of loading then after 3 and 6 months. Results: The retention values before the insertion of overdenture (T0) were considerably low in comparison with those at time of insertion of overdenture (T1) and after 3 months from denture insertion (T3). Regarding the ISQ values, there was no significant difference between the two groups before and at the time of insertion of implant while there was a significant difference between the two groups with better stability results in the locator attachment group after 3 months (P < 0.05). Conclusion: Within the limitation of this study, both types of attachment systems, i.e., Ball/O-Ring and locator attachments are reliable modalities for improving the retention and stability of implant-retained mandibular overdenture with superior initial stability results for the locator attachment.","PeriodicalId":212982,"journal":{"name":"Journal of Dental Implants","volume":null,"pages":null},"PeriodicalIF":0.0,"publicationDate":"2019-03-01","publicationTypes":"Journal Article","fieldsOfStudy":null,"isOpenAccess":false,"openAccessPdf":"","citationCount":null,"resultStr":null,"platform":"Semanticscholar","paperid":"132444756","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}
