Materials and Methods: Two different commercially available composite resin restorations; short fiber-reinforced (ever X Posterior GC, Tokyo Japan) and conventional micro-hybrid (G-aenial universal resin composite GC, Tokyo Japan) resin composite restorative material bonded with a universal adhesive (G-Premio BOND GC, Tokyo Japan) were used in the current study. A total of 40 sound maxillary human premolars were selected for the cuspal deflection test and received standardized MOD cavity preparations suitable for each test. The sample was divided into four groups; Group A: conventional microhybrid resin composite (conv.), Group B: short fiber-reinforced composite (SFRCs), Group C: short fiber-reinforced composite laminated with conventional microhybrid resin composite (SFRCs+conv.), Group D: short fiber-reinforced composite \"cut off\" then laminated with conventional microhybrid resin composite. Measuroscope was used to evaluate the cuspal deflection. For the cuspal deflection test, the collected data from each test were tabulated, coded and then statistically analyzed. One-way ANOVA followed by a post-hoc Tukey test was used for multiple comparisons. The level of significance was set at P < 0.05. Results: Both Group A (conv.) and Group C (SFRCs+conv.) showed insignificant differences in cuspal deflection values, in comparison with groups B ( SFRCS) and D (Cut off) (p > 0.05). There were significant differences in cuspal deflection between Group A (conv.) and group c (SFRCs+conv.) (p < 0.05). There were significant differences in cuspal deflection between groups, B( SFRCS) and group D (Cut off) (p < 0.05). Conclusions: Conventional resin composites exhibit higher cuspal deflection values than those containing short fibers. Laminating conventional resin composite to SFRCS, as per the manufacturer's instructions, increases cuspal deflection values more than SFRCS. The cut-off technique seems to have a positive effect on the cuspal deflection value.","PeriodicalId":308616,"journal":{"name":"Mansoura Journal of Dentistry","volume":"28 1","pages":"0"},"PeriodicalIF":0.0,"publicationDate":"2023-06-01","publicationTypes":"Journal Article","fieldsOfStudy":null,"isOpenAccess":false,"openAccessPdf":"","citationCount":null,"resultStr":null,"platform":"Semanticscholar","paperid":"124795976","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: Forty roots of extracted lower primary molars were obtained and divided into 4 groups according to the type of irrigant: Group 1 (control) NaOCl 2.5%, Group 2 (12.5% turmeric irrigant), and Group 3 (25% propolis irrigant) and Group 4 (saline). Root canals were contaminated with E. faecalis bacteria. Bacterial counts were performed from samples that were taken from each canal pre-irrigation and post-irrigation. Data was analyzed using t-test and ANOVA. Results: There were statistical differences between all groups; NaOCL and turmeric extract showed a high effective reduction of a bacterial number followed by propolis. A slight reduction of E. faecalis was demonstrated following saline irrigation. Conclusions: All herbal irrigation solutions showed effective eradication of E . faecalis and can be used as an alternative to NaOCL in the irrigation of infected root canals of primary teeth.","PeriodicalId":308616,"journal":{"name":"Mansoura Journal of Dentistry","volume":"23 1","pages":"0"},"PeriodicalIF":0.0,"publicationDate":"2023-06-01","publicationTypes":"Journal Article","fieldsOfStudy":null,"isOpenAccess":false,"openAccessPdf":"","citationCount":null,"resultStr":null,"platform":"Semanticscholar","paperid":"122784303","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}

Enan, Noha A. El-wassefy","doi":"10.21608/mjd.2023.288120","DOIUrl":"https://doi.org/10.21608/mjd.2023.288120","url":null,"abstract":": Objective: To evaluate the influence of adding different antibiotics to glass ionomer cement (GIC) on its surface roughness, water sorption, and solubility. Materials and Methods: A two-component GIC system (Fuji IX) and commercially available antibiotic tablets including ciprofloxacin and amoxicillin /clavulanate were used. The two types of powdered antibiotics were incorporated and stirred with the GIC powder at a ratio of 2 wt%. A total number of 120 Specimens were prepared using a split Teflon mold and grouped as follows; group I: Conventional GIC as a control group, group II : Ciprofloxacin-modified GIC, group III : (Amoxicillin/Clavulanate)-modified GIC, group IV : a combination of the two antibiotics-modified GIC. Each group was tested for surface roughness using a profilometer. Water sorption and solubility were evaluated after 7 days of immersion in distilled water. The collected data of each test were statistically analyzed using a two-way analysis of variance (ANOVA) followed by post-hoc Tukey multiple comparisons. The level of significance was set at P ≤ 0.05. Results: For water sorption, the highest mean value was recorded in group II while the lowest value was reported in group III. For the solubility test, the greatest median value was recorded in group IV with the least value recorded in group III. For surface roughness, the highest mean Ra value was found in group II while the least value was reported in the control group (group I). Conclusions: The present in vitro study demonstrated that the incorporation of 2% of antibiotics into glass ionomer cement leads to increase solubility, water sorption, and surface roughness of GIC.","PeriodicalId":308616,"journal":{"name":"Mansoura Journal of Dentistry","volume":"379 1","pages":"0"},"PeriodicalIF":0.0,"publicationDate":"2023-03-01","publicationTypes":"Journal Article","fieldsOfStudy":null,"isOpenAccess":false,"openAccessPdf":"","citationCount":null,"resultStr":null,"platform":"Semanticscholar","paperid":"121665335","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: A total number of 24 standardized cuboid composite blocks were fabricated with the aid of teflon split mold (25×4×4) mm dimensions. Half of these composite blocks were made from a universal nanohybrid methacrylate-based composite and the other half was made from a universal nanohybrid Ormocer based. The top surfaces of all mounted specimens were surface treated with sandblasting, silane coupling agents, and universal adhesive of the same brand of composite. Four cylindrical composite rods (2 mm height, 3 mm internal diameter) were built over each composite block and filled with the repair composite from the same material with the aid of tygon tubes. Composite blocks of both groups were divided into two sub-groups according to the previous treatment of repairing materials (preheated or not preheated). Then half of the blocks with their attached repair materials were stored for 24 h to evaluate the immediate bond strength and the other half was stored in distilled water for 6 months to evaluate the bond durability. Shear bond strength was measured using a universal testing machine (Instron), and the collected data were statistically analyzed with three-way ANOVA and post-hoc Tukey test. Results: The outcome of three-way ANOVA revealed that there was a statistically significant difference between the repair bond strength of Methacrylate & Ormocer groups immediately and after 6 months of storage (p=0.03). No statistically significant difference was found between the repair bond strength of the preheated and non-preheated immediately and after 6 months of storage (p=0.7). Conclusions: Immediate and delayed repair bond strength of methacrylate-based resin composite was superior to Ormocer based composite within the preheated group. Preheating of both methacrylate and Ormocer composite did not affect immediate and delayed repair bond strength.

Materials and Methods: CBCT records of 108 patients were evaluated to detect the presence, location, size, and number of lingual foramina using axial, and cross sectional images. Results: A total of 463 lingual foramina (representing 100% of all patients) were found. Individuals had between one and eight lingual foraminaon their jaw, with the majority of cases having four (24.1%). Regarding the size; 336 (72.7%) were ≤1 mm and 127 (27.3%) were >1 mm. Regarding the location, only 162 (35%) were LLF, while most of the lingual foramina were MLF (65%). Moreover 23 (21.3%) had lingual foramina on only one side of the mandible, and 85(78.7%) had them on both sides of the mandible. Conclusions: CBCT can be used to detect the presence, size, number, and location of mandibular lingual foramina. It is very crucial to recognize characters of these foramina prior to any surgical treatment to avoid operative complications.","PeriodicalId":308616,"journal":{"name":"Mansoura Journal of Dentistry","volume":"43 1","pages":"0"},"PeriodicalIF":0.0,"publicationDate":"2023-03-01","publicationTypes":"Journal Article","fieldsOfStudy":null,"isOpenAccess":false,"openAccessPdf":"","citationCount":null,"resultStr":null,"platform":"Semanticscholar","paperid":"130627184","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}
