Undiscovered roots or canals may lead to a reduced prognosis of a treated tooth as hidden causative organisms and their by-products can cause re-infection. Most maxillary first molars have three roots, namely mesio-buccal (MB), disto-buccal (DB) and palatal (P). They can be separate or fused, with incidences varying between populations. Anomalies have also been documented that include single rooted, double-rooted, four and even five-rooted teeth. Additional roots are mostly in the form of additional palatal roots and are known as either a radix mesiolingualis (RML) or radix distolingualis (RDL). This paper is the first of two giving an overview, focused on micro-CT, of available literature on various aspects of the root and canal morphology of the maxillary first permanent molar.

Pregnancy and the postpartum period are considered a phase where women have an increased vulnerability to mental disorders. Studies have shown that around 12% of pregnant women experience depression in the antenatal period and the prevalence of postpartum depression ranges from 10%- 15%.1 These psychiatric disorders are not only associated with poor maternal health but also with negative effects on children, affecting the cognitive development and behaviour.1 Studies have also shown that there is a strong correlation between the oral health knowledge, practice and behaviour of the mother and the oral health status of the young child. Mothers who have poor oral health often have children who have higher levels of early childhood caries (ECC). Mothers with mental disorders have also been shown to be unable to take care of their own health optimally thereby also placing the health (and oral health) of their children at risk. Due to a lack of longitudinal studies investigating the influence of maternal depressive disorders on the occurrence of child’s dental caries, da Fonseca Cumerlato and colleagues from Brazil (2023)1 reported on a study that sought to investigate the effect of the trajectory of maternal depressive disorders in the first thousand days of the child’s life on the prevalence of early childhood dental caries at 48 months of age in a birth cohort.","PeriodicalId":515896,"journal":{"name":"South African Dental Journal","volume":"29 16","pages":""},"PeriodicalIF":0.0,"publicationDate":"2024-03-06","publicationTypes":"Journal Article","fieldsOfStudy":null,"isOpenAccess":false,"openAccessPdf":"","citationCount":null,"resultStr":null,"platform":"Semanticscholar","paperid":"140262827","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}

Bond strength is important for the clinical success of adhesive material. The shear bond strength (SBS) is the maximum force that an adhesive joint can tolerate before fracture which is tested by SBS tests. The high bond strength helps the adhesive to resist stresses caused by resin contraction and forces for a longer time and thus prevents the problems of bond failure such as recurrent caries, tooth sensitivity and restoration failure. GIC as a restorative material has the capacity to release fluoride and shows good bonding ability. The use of GIC in anterior applications appears to be satisfactory, but they have limitations for use in permanent posterior teeth, particularly with regard to large restorations. Zirconia-reinforced GI (Zirconomer, Shofu Inc, Japan) is a new class of restorative material containing reinforced glass ionomer with special zirconia fillers that promises the strength and durability of amalgam with the protective benefits of glass ionomer while eliminating the hazards of mercury. Amalgomer CR (Advanced Health Care, Tonbridge, Kent, UK), a novel ceramic-reinforced GIC, was introduced, which combines the benefits of GIC with the high strength of ceramics. In the present study, shear bond strength to the dentin with Zirconomer, Amalgomer CR and Fuji type IX GIC (GC Tokyo) are compared.","PeriodicalId":515896,"journal":{"name":"South African Dental Journal","volume":"47 7","pages":""},"PeriodicalIF":0.0,"publicationDate":"2024-03-06","publicationTypes":"Journal Article","fieldsOfStudy":null,"isOpenAccess":false,"openAccessPdf":"","citationCount":null,"resultStr":null,"platform":"Semanticscholar","paperid":"140262058","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}
