Objective: The objective of this in vitro study was to evaluate the marginal accuracy of different CAD/CAM ceramic crowns after thermo-mechanical cyclic loading. Material and methods: The marginal accuracy of a polymer-infiltrated ceramic network (PICN) material (Vita Enamic [VE]) was compared to two machinable glass ceramics; Zirconia-reinforced lithium silicate (Vita Suprinity [VS]) and a lithium disilicate glass ceramic (IPS e.max. CAD, IPS). 30 natural premolar teeth of average size were prepared (n=10 each group) by computer numerical control (CNC) to fulfill the criteria of all ceramic crown design. Optical impressions were taken for each tooth preparation using the CAD/CAM scanner. 30 crowns were milled from ceramic blocks based on the optical data. A total of 30 crowns were fabricated using CAD/CAM system, and divided into three groups (IPS e.max, VE and VS). The vertical marginal gap was measured using stereomicroscope before, after cementation and after thermo mechanical cyclic loading. Results: No statistically significant difference in vertical marginal gap within or between groups of three tested materials before, after cementation and after thermo mechanical cyclic loading. Conclusions: Vertical marginal adaptation of all tested ceramics was within the clinically acceptable values.

Objective: To evaluate and compare the efficacy of Mandibular protraction appliance IV (MPA-IV) and PowerScope (PS) in the treatment of skeletal Class II malocclusion patients. Subjects and methods : A total of 16 circumpubertal class II patients (ANB°>4°) with mandibular deficiency were randomly divided equally into two groups; group 1: treated by MPA-IV, their mean age was 14.98 ± 1.33 years, group 2: treated by PS appliance (American Orthodontics, Sheboygan, Wis), their mean age was 14.67 ± 1.37 years. In both groups, fixed functional appliances were installed for six months. Treatment outcomes were assessed by cephalograms taken immediately pre-and post-functional appliances therapy. Results : Intergroup comparisons of the mean treatment changes revealed significant improvements (P ≤ .05) in SNB°, SN-Pog°, Ar-Go-Me°, Co-Gn mm, B-Sv mm, Pog-Sv mm, S-Go mm, and lower lip advancement (Li-Sv mm and Pog’-Sv mm) in MPA-IV group. While in the PS group, there were significant greater decrease of SNA° and upper incisors retraction (P ≤ .05). Conclusion: Both appliances could be used efficiently in the treatment of class II malocclusion. MPA-IV produces superior mandibular advancement and lower lip projection, while the effects of PS are mainly dentoalveolar changes.

Objective: The collapse of bone is considered to be a normal physiological change following the extraction if no measure of socket preservation was applied. This study was performed using pericardium collagen membrane and xenograft for horizontal width augmentation simultaneously with the placement of implant. To evaluate the amount of new bone gain cone beam computed tomograpghy (CBCT) was used. Subjects and methods : Fifteen patients who met the inclusion criteria were selected from outpatient clinic in the Faculty of Dentistry, Al-Azhar University (boys-Cairo). All the patients showed narrow width in the lower posterior edentulous ridge that need to be restored by implant placement. All the cases had guided bone regeneration procedure using xenograft and pericardium membrane. The ridge width was measured preoperatively and 6 months post operatively using (CBCT) to evaluate the amount of bone gain. Results: The ridge width showed a significant increase from 4.51±0.56 pre-operatively to 6.61±0.44 immediately post-operative. This was followed by a decrease to 4.71± 0.6 after 6 months postoperatively. There was no significant difference between values recorded pre-operatively and after 6 months. Conclusion: The results of the current study do not support the use of bovine pericardium membrane with xenografts in horizontal bone augmentation simultaneously with implant placement.

Objectives: This study was designed to evaluate the effect of using tricalcium phosphate combined with platelet rich fibrin versus platelet rich plasma in post extraction socket clinically and radiographically at maxillary esthetic zone. Subject and methods: This study was conducted on 30 patient seeking extraction of at least one hopeless tooth, they distributed into 3 groups.10 patients for control group , 10 patients for test group (a) and 10 patients for test group (b). In control group the socket was left to heal spontaneously by clot formation. In test group (a) the socket was filled with beta-tricalcium phosphate as bone graft and platelet rich fibrin. In test group (b) the socket was filled with beta-tricalcium phosphate and platelet rich plasma. CBCT image was taken to compare the vertical, horizontal ridge dimension and bone density pre-operatively and 6 month post-operatively. Result: There was statistically non-significant difference regarding the vertical height, bone width, buccal plate thickness and bone density in both groups pre-operatively. But after 6 months post-operatively there was statistically significant difference regarding three groups in all parameters. The test group (a) that represented βTCP and PRF showed a lower percentage of a change than test group (b) that represented βTCP and PRR than control group. Conclusion: The use of PRF accelerates socket wound healing after tooth extraction as noticed by reducing vertical and horizontal bone loss and maintaining favorable bone density values after 6 months postoperatively.

Objectives: The aim of the study is to evaluate the effectiveness of titanium prepared platelet rich fibrin (TPRF) for treatment of gingival recession and comparing it to platelet rich fibrin (PRF). Subjects and methods : This study was conducted on subjects having multiple gingival recession. Twenty-four patients of both sexes, aged between (23-41) and having miller class I, II were selected to participate in the present study. Subjects were randomly divided into two equal groups with coin toss method. The plaque index, gingival index, Periodontal pocket depth, Recession width, Recession depth, Clinical attachment level, Keratinized tissue width, keratinized gingival mucosa, Gingival thickness, T-TRF membrane thickness, and VAS were measured. Results : At 6 and 9 months: there was a statistically significant difference in mean RD in the two groups. T. PRF group showed a less mean RD, RW, and KTW than PRF group. At 9 months: T. PRF group showed a significant higher mean GT than PRF group. At day 3 and 7: T. PRF group showed a significant lower mean VAS than PRF group. Conclusion: In conclusion Within the limits of this study, the results demonstrated that T-PRF procedure is a safe, effective method in treating gingival recessions. In addition, this procedure can be recommended to treat localized or multiple-adjacent gingival recessions without additional surgery. However, future randomized clinical trials with a split-mouth design and larger sample size are essential for evaluating the TPRF efficiency in gingival

However, future randomized clinical trials with a split-mouth design and larger sample size are essential for evaluating the TPRF efficiency in gingival","PeriodicalId":117944,"journal":{"name":"Al-Azhar Journal of Dental Science","volume":"23 1","pages":"0"},"PeriodicalIF":0.0,"publicationDate":"2023-07-01","publicationTypes":"Journal Article","fieldsOfStudy":null,"isOpenAccess":false,"openAccessPdf":"","citationCount":null,"resultStr":null,"platform":"Semanticscholar","paperid":"114592515","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}

Objectives: The aim of the present study was to compare the effectiveness of silver diamine fluoride (SDF) and sodium fluoride varnish in arresting caries progression on primary teeth. Subjects and methods: This study involved a total of 60 teeth categorized according to the restored primary teeth in two main groups; group A; Anterior teeth (n=30); group B; Posterior teeth (n=30). Then, the anterior teeth were subdivided into two subgroups (n=15); teeth restored with SDF alone (A1) or restored with NaF alone (A2) (n=15). While, the posterior teeth were subdivided into subdivided into two subgroups (n=15); teeth restored with SDF with ART “SMART” (B1) or restored with NaF with ART “SMART” (B2). The clinical and radiographic results in this study was evaluated after 3-months. Results: SDF showed significant clinical success when compared to NaF alone or when used under ART “SMART” technique. While, the anterior teeth showed better results than posterior teeth.the anterior teeth showed significant radiographic success when compared to posterior teeth. Conclusion: The use of SDF solution has better clinical and radiographic outcomes in caries arrest of primary teeth. SDF solution has better caries arrest outcomes in non-cavitated lesion than cavitated lesions in primary teeth.
