This study was performed to assess differences in oral health needs using normative and sociodental approaches among geriatric patients in Mansoura city. Materials and Methods: This study was of descriptive cross-sectional design based on close ended questionnaires and interviews in addition to the clinical examinations of both past caries experience and periodontal disease state of the patients. Five hundred healthy participants aged ≥ 60 of both genders were randomly selected from urban and rural areas in Mansoura city. Results: Only 2% of the sample had oral lesions and just 2.8% showed root caries. On the other hand 86.8% had periodontitis, 58.8% had decayed teeth, 99.2% had filled teeth, and 65.8% had missed teeth. Impact related needs of the studied population showed that the highest percentage 23.4%, 23.2% significantly reported their teeth as average and good respectively, while the lowest percentage 4%, 7.2% significantly described their teeth as excellent and very poor. Regarding gums the highest percentage 32.8%, 25.4% significantly labeled their gums as average and good respectively, while the lowest percentage 0.6%, 5.2% significantly defined their gums as excellent and very poor. Also, the mean impact of physical domain was 1.73 ± 0.64, psychological domain was 1.56 ± 0.83 and social domain was 1.40 ± 0.57 which indicated that the most participants did not have problems. In Propensity related needs 36.4% did not clean their teeth, and 27% cleaned once a day and 59.2% used toothbrush with toothpaste. Results showed 64.6% did not smoke cigarettes, and 78% did not smoke sheesha. Conclusion: The elderly population in urban and rural areas in Mansoura center had low mean impact related needs regarding the three domains. There is an urgent need to persuade people to adopt preventive therapy while also seeking medical interventions to enhance the retention of natural teeth into advanced age. Provision of oral health care to older people will not only lead to economic savings but will also reduce the burden of the caregivers.","PeriodicalId":308616,"journal":{"name":"Mansoura Journal of Dentistry","volume":"15 1","pages":"0"},"PeriodicalIF":0.0,"publicationDate":"2021-12-01","publicationTypes":"Journal Article","fieldsOfStudy":null,"isOpenAccess":false,"openAccessPdf":"","citationCount":null,"resultStr":null,"platform":"Semanticscholar","paperid":"116707518","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}

Purpose: This study evaluated the fracture resistance of endocrowns with two preparation designs and manufactured with two CAD/CAM ceramic materials. Materials and Methods: Forty endodontically treated maxillary 1 molar teeth were prepared to receive endocrown restorations and divided into two main groups according to the preparation designs: Group B (n=20) endocrowns with butt joint design; Group F (n=20) endocrowns with ferrule design. The main groups were subdivided into two subgroups according to the CAD/CAM material used: Subgroup E (n=20) endocrowns manufactured from lithium disilicate glass ceramic (LD) (IPS e.max CAD, Ivoclar-Vivadent, Liechtenstein); Subgroup C (n=20) endocrowns manufactured from hybrid nano-ceramic (HN) (Cerasmart 270, GC, Japan). The endocrown restoration were cemented to the prepared teeth using dual cured self-adhesive resin cement. The specimens were subjected to thermal aging up to 10.000 cycles in a thermocycling paths with 5C and 55C. All specimens were subjected to a compressive force until fracture occur by using universal testing machine. The maximum compressive force was recorded for all specimen; then the failure modes were examined using scanning electron microscope SEM. Results: The mean value of fracture resistance of BC group was statistically and significantly higher than the other tested groups; (BC group, 4361.01±554.32 N) and the lowest mean value was recorded with FE group (2693.04±638.69 N). B Group showed significant higher fracture resistance than F Group (B group, 3707.09±1156.06 N; F group, 2724.34±601.96 N). C subgroup showed significant higher fracture resistance compared to that of E subgroup (C subgroups, 3558.33±995.92 N; E subgroups, 2873.10±983.95 N). All groups showed a high rate of catastrophic failures but at loads greater than normal maximum masticatory forces. Conclusions: Butt joint design endocrowns exhibited significantly higher fracture resistance than ferrule design endocrowns. Hybrid nano-ceramic endocrowns showed higher fracture resistance than lithium disilicate endocrowns. Endocrown showed a high percent of irreparable failure mode but at loads larger than normal masticatory function.","PeriodicalId":308616,"journal":{"name":"Mansoura Journal of Dentistry","volume":"1 1","pages":"0"},"PeriodicalIF":0.0,"publicationDate":"2021-09-01","publicationTypes":"Journal Article","fieldsOfStudy":null,"isOpenAccess":false,"openAccessPdf":"","citationCount":null,"resultStr":null,"platform":"Semanticscholar","paperid":"127459345","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}

Also to investigate both micromorphological and elemental analysis of restorations-tooth interfaces Materials and methods: For μSBST, a total of 30 mandibular first molars were vertically splitted. The resulted 60 intact single roots were prepared and embedded into acrylic blocks. Then, they were randomly divided into 3 main groups(n=20) according to restorative material. Group A; Conventional GIC (Riva self cure,SDIltd,Australia), group B; CPP-ACP modified GIC ( FujiVII-EP, GC corp., Japan ) and group C; RMGIC (Riva light cure, SDI ltd., Australia). All the 60 samples were conditioned first with 25% PAA (RIVA Conditioner SDI ltd, Australia). Then, each group was further divided into 2 subgroups (n=10) according to application of SDF/KI (Riva Star,SDIltd,Australia), control subgroup (I) without SDF/KI and tested subgroup (II) pretreated with SDF/KI. Then, tygon tube with diameter of 1.2mm and 3mm height was used in GIC application on root surface. After GICs application , there were 60 specimens with 60 material microcylenders bonded to its surface. The specimens were stored in distilled water for 24hrs prior to μSBST. Then, each one was mounted to universal testing machine individually for μSBST. Afterwards, failure mode of all debonded specimens were analyzed by stereomicroscope and SEM. For micromorphological analysis and following the same study design, additional 6 molars were restored with GIC at their bifurcation area as one for each subgroup. They were vertically sectioned to expose restoration-tooth interfaces. Every half was prepared as one for normal and the other for acid base challenge techniques. All the normally prepared halves were subjected to EDX for elemental analysis first then all halves were sputter coated with gold prior to be scanned using SEM.The collected data from μSBS test were tabulated, coded and statistically analyzed using IBM-SPSS software (version 26.0, IBM, NY, USA). One-way ANOVA followed by Tukey post-hoc test was used for multiple comparisons. The level of significance was set at (p<0.05).

Materials and methods: A total of 64 machinable composite discs (MZ100 paradigm) were fabricated using CAD/CAM technology according to the desired dimensions (10 mm width and 4 mm thickness). The discs were divided in two main groups (n=32): as milled group (AM) and sandblast group (SB) used Al2O3 (50-μm). Each main group was subdivided into two subgroups (n=16) according to method of chemical conditioning: conventional silane (SI) and multipurpose primer (MP). Composite resin discs were fabricated according to desired dimensions (4.5 mm width x 3.5 mm thickness). Surface treated MZ100 discs were bonded to the composite resin discs according to the types of adhesive resin cements, multistep adhesive resin cements or self-adhesive resin cements. One hour after bonding, all specimens were stored in water bath at 37°C for 5 months followed by thermocycling for 10,000 cycles. Following artificial aging all bonded specimens underwent shear bond strength testing using universal Instron testing machine. Assessment of the debonding failure mode was done by Binocular optical microscope and SEM. Statistical analysis was performed using a 3-Way ANOVAs.Results: In Three-Way ANOVAs test revealed statistically significant different in SBS between (SB) and (AM) groups {p=0.000} and between different resin cements used {p=0.006}.
