Methods: A total of 110 endocrowns, 55 lithium disilicate endocrowns (group I) (IPS e. max CAD) and 55 of bonded CAD/CAM resin composite endocrowns with fiber reinforced FRC base (group II) (Grandio) were used to restore endodontically treated molars. First shade selection was performed followed by cavity preparation and digital impression. Then restorations were designed, milled and checked intraorally before cementation using resin cement. The restorations were evaluated at baseline, 6 and 12 months using Modified USPHS criteria. Statistical analysis was performed with SPSS 20®, Graph Pad Prism® and Microsoft Excel 2016. Results: Regarding fracture and marginal adaptation, all restorations in both groups had Alpha score (100%); at base line, after 6, and 12 months. Regarding retention, all restorations in both groups had Alpha score (100%); at base line, and after 6 months. While after 12 months, only one case had Charlie score in group I with insignificant difference between groups as P=0.32. Regarding shade match, all restorations in both groups had Alpha score (100%); at base line while after 6 months two cases were Bravo in group II with insignificant difference between groups as P=0.14. While after 12 months, three cases were Bravo in group II with insignificant difference between groups as P=0.07. Conclusion: CAD/CAM resin composite endocrowns with fiber reinforced FRC base are just as dependable as lithium disilicate for restoring non-vital posterior teeth.","PeriodicalId":11504,"journal":{"name":"Egyptian dental journal","volume":"123 22","pages":""},"PeriodicalIF":0.0,"publicationDate":"2024-07-01","publicationTypes":"Journal Article","fieldsOfStudy":null,"isOpenAccess":false,"openAccessPdf":"","citationCount":null,"resultStr":null,"platform":"Semanticscholar","paperid":"141697168","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 & Methods : 14 completely edentulous patients were selected from the out-patient clinic, Removable Prosthodontic Department, Beni-Suef University with age range 45–55 years with a good general and oral health. Each patient received two set of dentures, CDs and 3D printed dentures. They were asked to wear and use each denture set for 3 months but with a 2-week wash out period between them.

Results : There was a statistically significant increase in the mean values of BF in the two studied groups with insignificant difference between mean values of BF between the right & left sides and BF mean values were significantly higher with the 3D printed dentures than with the conventional complete dentures.

Materials and methods: The current study used thirty extracted incisors. Ten teeth(n = 10) in each group had a remineralizing treatment: group 1:rosemary, group 2: ginger, and group 3: sodium fluoride varnish. A nail polish was applied on labial surfaces except to a window of 4x4mm and the microhardness test was done.

The remineralizing agents were applied to each group for ten days. The samples were immersed in artificial saliva between treatments. Lastly, microhardness test was conducted. Results: ANOVA test was used to Compare between groups. Comparison within the same group was performed using a paired t-test. The Fluoride group was not significantly different than the other 2 groups after remineralization, The mean value was 63.04±3.79 in the fluoride group, in comparison to 64.01±3.85 in the Ginger group and 62.20±3.91 in the Rosemary group. The mean value recorded in the rosemary group was significantly higher than ginger group (p=0.047).

Methodology: Selected patients were seeking emergency treatment of painful symptomatic irreversible pulpitis with symptomatic apical periodontitis for single rooted teeth. Sixty-eight male patients, 25 to 50 years old were distributed randomly in 4 groups of 17 each according to the final irrigation protocol: control (GI): NS at room temperature, control (GII): CHX at room temperature, intervention (GIII): cryo with NS (cryo/NS), , and intervention (G IV): (cryo / CHX) before final obturation in the same visit. Patients were trained and asked to report pain incidence and level after12, 24, 48, 72 hours and at 7 days as well as frequency of analgesic intake. Kruskal Wallis, followed by Dunn`s multiple comparisons test were used for comparison between the 4 groups, while Chi square test was used for qualitative data. The significance level was set at p ≤0.05. Results: G III: (cryo/NS) and G IV: cryo/CHX showed significantly highest pain reduction after 24, 48, and 72 hours P= 0.000 I. Significantly more prolonged pain reduction curve was found in GI: cryo/NS. Pain in both tested groups declined to no pain after 7 days. Frequency of analgesic need was insignificant for the two groups P=0.27. Conclusions: From the results of the present study it appeared clearly that cryo helped in pain reduction whether used with CHX or NS. CHX used as a cryo material showed insignificant trend toward effective time dependent pain reduction as compared to NS. This might be because of its substantivity. Further study is needed to better clarifying this point.","PeriodicalId":11504,"journal":{"name":"Egyptian dental journal","volume":"104 2","pages":""},"PeriodicalIF":0.0,"publicationDate":"2024-07-01","publicationTypes":"Journal Article","fieldsOfStudy":null,"isOpenAccess":false,"openAccessPdf":"","citationCount":null,"resultStr":null,"platform":"Semanticscholar","paperid":"141697249","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}

To evaluate the effect of two preparation designs of partial laminate veneers on the fracture resistance of anterior teeth with full and half incisal edge fracture. Materials and Methods. 48 upper central incisors were divided into four equal groups: two groups simulated completely fractured incisal edge: Group (Full/Cham): with chamfer design and Group (Full/Bev): with bevel design and two groups simulated half fractured incisal edge: Group (Half/Cham): with chamfer design and Group (Half/Bev): with bevel design. Lithium disilicate partial veneers were constructed and cemented using light-curing resin cement. All samples were mounted on universal testing machine to test their fracture resistance. Fractured samples were categorized as restorable or non-restorable based on the crack/fracture extension relative to the cemento-enamel junction. Results. Group (Full/Cham): (361.05 ± 11.39 N) had significantly the highest fracture resistance, followed by Group (Full/Bev): (207.1 ± 10.85 N), while Group (Half/Cham): (123.16 ± 6.63 N) and Group (Half/Bev): (123.75 ± 6.12 N) had significantly the lowest values with insignificant difference between them. All teeth with half incisal edge fracture revealed restorable fractures, while with full incisal edge fracture the percentage dropped to third (33.3%). Conclusions. In full incisal edge fractures, chamfer design had better fracture resistance than bevel design. While in half incisal edge fractures, both designs had similar fracture resistance and restorable mode of failure. Clinical Relevance.

Implant-supported restorations were designed then milled with CAD wax and divided into 2 groups according to material (n=14): Lithium disilicate and BioHPP. Each group was pressed according to the manufacturer’s instructions. The marginal and internal adaptation of the specimens were analyzed using DOT & subtractive RET. Data were explored for normality using Shapiro-Wilk’s and Levene’s tests and were analyzed using independent and paired t-test for inter and intragroup comparisons respectively with a significance level of p<0.05. Agreement analysis was done using intraclass correlation coefficient (ICC). Results: BioHPP screw-retained implant-supported crowns showed higher marginal gap than lithium disilicate, yet the difference was non-significant when measured using DOT, while it was significant when measured using sRET. Calculated agreement between the two techniques at the marginal level showed that there was a statistically significant moderate agreement between both methods. Regarding internal adpatation, BioHPP had a statistically significant higher internal gap than lithium disilicate group.
