Five individuals had a complete dental clinical examination and molecular analysis performed using direct sequencing of the exon 4 and an adjacent region with 23 base pairs of the IRF6 gene.Results: Features of VWS reported in family history were present in 36.4% (28/77) of all family members; of these 57% (16/28) had pits in the lower lip, 36% (10/28) had both pits and orofacial clefts and 7 % (2/28) had only orofacial clefts. Developmental dental anomalies were observed in three individuals. The sequence analysis of exon 4 of the IRF6 gene carried out for 4 family members revealed the presence of the SNP rs7552506 (c.175-5C> G) located in five base pairs before the start of exon. The analysis of exon 4 of the IRF6 gene also revealed a new variant c.269G>C (p.Ser90Thr) which causes exchange of the Serine amino acid residue for the Threonine residue. Conclusions: The c.269G>C(p.Ser90Thr) can interfere with multimeric interactions and with protein conformation that will be slightly destabilized, because the mutant residue is bigger than the wild-type residue. The phenotypic variations in the cases studied, despite carrying the same genetic mutation, suggest that distinct genetic modifiers operate on the formation of clefts and dental development.","PeriodicalId":37056,"journal":{"name":"Dentistry 3000","volume":" ","pages":""},"PeriodicalIF":0.0,"publicationDate":"2021-11-04","publicationTypes":"Journal Article","fieldsOfStudy":null,"isOpenAccess":false,"openAccessPdf":"","citationCount":null,"resultStr":null,"platform":"Semanticscholar","paperid":"44425472","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 specimens were exposed to one of these mouthwashes twice a day for 60 seconds: Listerine, chlorhexidine, Orthokin, Persica, fluoride and artificial saliva as the control group. The elastomeric chains and NiTi springs were stretched so that they exert the initial force of 250 gr. Their force was measured on the 1, 7, 14 and 28 following days by means of a digital gauge.Results: Elastomeric chains and coil springs had force decrease over time, but EC' force reduction was greater with the highest reduction rate in the first week. However, in the CS group, the force decrease wasn't statistically significant in the first two weeks. After 28 days in the control groups, 49.8% of the initial force was remained in ECs while the value was 93.3% for CSs. In comparison between mouthwashes, in EC groups, in all mouthwashes except Persica, the remained force was statistically less than control group.Conclusion: Force degradation of elastomeric chains could be exacerbated by use of mouthwashes. About coil springs, force decay was also observed. However, it was not statistically significant. Force reduction was detectable after four weeks of coil springs usage, but in EC groups, the greatest reduction was after the first week.

The aim of this study was to investigate the effect of different placement time of RMGI (Resin Modified Glass Ionomer), composite resin and amalgam over different CSCs on the surface microhardness of these restorative materials.Methods: Each CSCs material (Biodentine, MTA, CEM cement) was mixed and carried into a hole (6mm diameter ×4 mm thickness) in the center of 270 molds (n=90 /each CSC). Then these molds were randomly divided into three main experimental groups (n=30) in regard of restorative materials (Amalgam, RMGI, Composite) that were placed in the other molds with the same hole size to make restorative materials and CSCs in contact together.

Methods: A full-crown preparation was simulated using dentin analogue (G10, Protec, São Paulo, Brazil) totaling 20 identical preparations. Next, twenty acrylic crowns were milled using different occlusal design parameter (Young or Adult) available in the software database. The crowns were cemented (Temp-bond, NE Kerr Dental, Brea, CA, USA) and fractured using a compressive load (0.5 mm/min of cross-head speed). Data were analyzed by using one-way ANOVA and Tukey tests (p< 0.05). A similar geometry was modeled and exported to the analysis software to perform a static structural analysis. The maximum principal stress was calculated using the finite element method with 300 N chewing load simulation. Results: The occlusal anatomy significantly influenced the load-to-fracture (p<0.05). Young design showed lower fracture load (1139±132 N) than Adult design (2007±345 N). The tensile stress distribution showed a similar pattern for both groups however the highest stress peak was calculated for Young design (76 MPa) in the occlusal surface.

Black triangle disease, or a lack of interdental papilla, is esthetically displeasing particularly in the central incisor region and has a hoard of etiologies ranging from gum disease to inherited tooth morphologic features. Addressing patients’ esthetic concerns must first be met with understanding the causation of the black triangles before treatment can be rendered. Genetic contributions are multifactorial, and this case report provides evidence for a case of a central incisor black triangles without other affected family members. Background: Black triangles are a prominent feature for those experiencing a lack of interdental papilla between central incisors and may dramatically affect the presentation of a person’s smile. The aim of this case report is to convey the importance of managing patients’ esthetic chief complaints while addressing the etiology of the esthetic concern. Case Description: A 24-year-old man presented to his dental colleague with concern of his black triangle spaces. The patient does not have gingival recession in the area of interest, and his biological mother and brother do not have black triangle spaces. Pathology is not an issue, but instead inadequate length of the central incisor mesial contact area prevents the interdental papilla from reaching the contact. Esthetics are a concern, but the patient is not interested in irreversible treatment for his healthy tissue. Practical Implications: Dentists should be aware of the multifactorial contributions to patients’ esthetic concerns. Dentists should also be aware that meeting a patient’s expectations may require a more complex treatment plan than the patient expected.","PeriodicalId":37056,"journal":{"name":"Dentistry 3000","volume":" ","pages":""},"PeriodicalIF":0.0,"publicationDate":"2021-03-10","publicationTypes":"Journal Article","fieldsOfStudy":null,"isOpenAccess":false,"openAccessPdf":"","citationCount":null,"resultStr":null,"platform":"Semanticscholar","paperid":"42698170","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}
