These are related, among other elements, to the type of connection with which the abutments and attachments are joined to the implant. For this reason, in this study we performed an overview of systematic reviews with FRISBEE methodology on the use of internal connections compared to external connections of dental implants for the treatment of single, partial, or total rehabilitation. Materials and Methods: We performed a systematic search in the Epistemonikos database. We extracted data from the included systematic reviews, reanalyzed data of primary studies, and generated a summary of findings table. We used RevMan 5.3 and GRADEpro for data analysis and data presentation. Eleven systematic reviews were included after full-text screening, which had thirty-three clinical trials. Results: The outcomes were analyzed: mechanical complication (RR: 0.64), biological complications (RR: 1.01), survival (RR: 0.99), and mean marginal bone loss (MD: 0.3 mm lower). Conclusion: The use of internal connections in dental implants could lead to less marginal bone loss and fewer mechanical complications than implants with external connections, however, the confidence in the effect is limited due to a low certainty of evidence for both outcomes. Additionally, results show that different implant connections do not have an impact on dental implant survival and biological complication rates, with a moderate and low certainty of evidence, respectively.","PeriodicalId":16138,"journal":{"name":"Journal of International Oral Health","volume":null,"pages":null},"PeriodicalIF":0.7,"publicationDate":"2023-05-01","publicationTypes":"Journal Article","fieldsOfStudy":null,"isOpenAccess":false,"openAccessPdf":"","citationCount":null,"resultStr":null,"platform":"Semanticscholar","paperid":"48550954","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 aim of this study was to evaluate the antimicrobial, cytotoxic, and mechanical properties of a novel chitosan-modified (CH) orthodontic primer and compare it with a control primer. Materials and Methods: This in-vitro study involved two groups (Group A: CH-modified primer and Group B: control primer). Antibacterial properties against Streptococcus mutans were evaluated using the agar well-diffusion technique to measure the zone of inhibition, and minimum inhibitory concentration (MIC) was evaluated using the two-fold diffusion technique. 3-(4,5-Dimethylthiazol-2-yl)-2,5-diphenyltetrazolium bromide (MTT) fibroblast assay was done to evaluate the cytotoxicity. After bonding brackets on extracted natural teeth the shear bond strength (SBS), contact angle (CA), and adhesive remnant index (ARI) were evaluated for both groups. Statistical analysis was done using SPSS software and the independent t-test and Mann–Whitney test were performed. Results: The CH primer when compared to the control primer had higher zone of inhibition values and lower MIC value. MTT fibroblast assay showed that the cell viability percent shown by the CH primer was more in comparison to the control primer. Statistically nonsignificant differences were found between the two primers for SBS (P > 0.05), CA (P > 0.05), and ARI (P > 0.05).

However, its bond strength to the dentin substrate is not known, especially for its use in primary teeth. Hence, the current study aimed to evaluate and compare the shear bond strength of two pulp capping materials, Biodentine and TheraCal PT in primary molars. Materials and Methods: In this experimental study, 28 non-carious human primary molars, which were nearing exfoliation, retained, or for orthodontic purposes, were extracted and collected. Using simple random sampling, they were randomly allocated into two groups with n = 14 in each group. Following occlusal flattening, cylindrical plastic tubes were stabilized and filled with TheraCal PT in group A and Biodentine in group B. All samples were incubated, subjected to universal testing machine, and analyzed under stereomicroscope for assessing the modes of failure. The statistical methods used were Independent t test, frequency, percentage (%), and Chi-square for intergroup comparison. The level of significance was kept at 0.05. Results: Significant differences in modes of failure were observed between TheraCal PT and Biodentine groups with P = 0.041. The modes of failure observed were mostly adhesive in group A compared with group B. The mean values of shear bond strength observed for groups A and B were 5.1 ± 3.5 and 3.1 ± 1.2 MPa, respectively.

Alpha-mangostin contained in mangosteen peel extract can reduce alveolar bone resorption while speeding up the bone formation process. This study determined whether the administration of α-mangostin decreases Interleukin-6 (IL-6) and increases Bone Sialoprotein (BSP) in the inflammatory process. Materials and Methods: The following four groups were subjected to an in-vitro assay to compare variations in the expression of inflammatory markers IL-6 and osteogenic markers BSP in LPS-induced cell line 7F2 cells before being administered α-mangostin. The bone sialoprotein (BSP), which is used as the osteogenesis marker of the effects of α-mangostin, is examined. Lipopolysaccharides (LPS) are employed in cell line 7F2 cultures of osteoblast cells to produce inflammatory effects. Real-time PCR was used to monitor the expression of genes related to inflammation and osteogenesis. Result: The Real-time PCR results showed that LPS can increase the expression of IL-6 by (15.12 ± 2.70), the administration of α-mangostin and LPS + α-mangostin can decrease the expression of IL-6 by (0.12 ± 0.04) and (0.25 ± 0.01). BSP expression increased in the provision of LPS and LPS + α-mangostin by (1.44 ± 0.33) and (3.13 ± 1.36), while in the administration of α-mangostin decreased by (0.96 ± 0.24).

This prevalidated 21-item questionnaire was sent through Google Form to different dental student groups. The questionnaire included details related to demography, knowledge related to TADs, and the role of continuing dental education in building the knowledge related to TADs. Descriptive statistical analysis and the chi-square test were used to evaluate the difference in the response to the questions among the different years of undergraduate students. Results: Approximately 88% of the interns could recognize that TADs are the Implants for skeletal anchorage and 57.8% defined TADs as “Implants for skeletal anchoring. Approximately 51.8% of the respondents felt that their knowledge was obtained from their undergraduate orthodontic studies. Sixty-one percent of the respondents stated their inability to diagnose cases that would benefit from orthodontic TADs. Most of the dental students from different years preferred the introduction of the TADs in the fifth-year curriculum. There existed a significant difference between the responses given by different-year dental students (P < 0.05).

Two calibrated observers evaluated the radiographs to minimize interobserver bias and error. A caliper was used to measure the length (in millimeters of the ESPs directly on the radiographs from the caudal margin of the tympanic plate to the tip of the SP). The ESP was considered present when the measurements were ≥30 mm. Results: This study indicates that the prevalence of the ESP was about 6.9% among the patients who attended the dental school clinic.

Materials and Methods: Two hundred forty sound human premolars had their enamel surfaces removed to expose even surfaces of dentin. The teeth were mounted in acrylic resin blocks and then assigned arbitrarily into four main groups (n = 60) representing the investigated adhesives (a self-etch [SE] adhesive, a total-etch [TE] adhesive, and a multimode [MM] adhesive used in TE and SE modes). Individually, the main groups were equally alienated into three subgroups (n = 20), each representing the number of the applied adhesive layers (one layer [1L], two layers [2L], and three layers [3L]). Then, each respective subgroup was divided subsequently into two equal divisions with n = 10 each according to thermocycling (with and without thermocycling). Each occlusal surface received three composite microrods. Prepared specimens were reserved in distilled water at temperature of 37°C until the μSBS test was performed after 24 h or after thermocycling for 3000 cycles at 5°C–55°C water bath. Results: A three-way analysis of variance (ANOVA) disclosed that multilayer application, adhesive type, and thermocycling showed a significant statistical impact on μSBS. The 1L, 2L, and 3L groups showed a statistically significant difference between the groups. The 3L groups showed the highest μSBS, whereas 1L groups recorded the least μSBS. Within the adhesive groups, a statistically significant difference was evident. The highest μSBS was recorded for TE, whereas SE recorded the least μSBS.
