The sequelae of chronic edentulous space is the supraeruption of the opposing teeth which hinders prosthodontic replacement. Molar intrusion of overerupted teeth can be done using miniscrew implants which serves as a promising technique, especially in adult patients. This case report highlights pre-prosthodontic therapy by pure molar intrusion using Temporary Anchorage Device (TAD) in an adult patient seeking prosthesis to enhance chewing efficiency.Primary orthostatic tremor (POT) is a rare movement disorder of unknown pathophysiology, characterized by fast tremor affecting a specific part of the body. The present paper reports a case of POT in mandible, discussing the approach and management. A 37-year-old male patient complained of involuntary mandibular movements, with onset 6 years ago, with no history of precipitating event. Usually, tremors were not present during patient's mastication or phonation. The oscillations presented rhythmically and symmetrically, with high frequency and low range of motion. Surface electromyography revealed an electromyographic discharge pattern bilaterally in the masseters, presenting a mean frequency of 13 Hz, and a predominance of postural type. Based on the history and clinical characteristics and electromyography, a diagnosis of POT was made. Several treatments have been employed over the years. Currently, the patient is being treated with buspirone hydrochloride 10 mg/day with a significant reduction of tremors. It can be concluded that knowledge of the characteristics of this condition is essential for the elaboration of a correct diagnosis and the better management of POT patients.Identification and management of ectopic supplemental tooth in anatomically complex areas such as the floor of orbit are challenging. This arises from the rarity and lack of consensus over management. The situation gets complex when there is an evidence of follicular pathology such as dentigerous cyst. In this report, a case of maxillary third molar associated with maxillary sinus and a distomolar in association with the floor of orbit medially to the inferior-orbital canal is presented. The surgical management of the condition is presented.Background Abfraction is a loss of tooth structure along the gingival margin and manifests with different clinical appearances. It has multifactorial etiology and may occur due to normal and abnormal tooth function and may also be accompanied by pathological wear, such as abrasion and erosion. The theory behind the abfraction is that the tooth flexure in the cervical area is caused due to occlusal compressive forces and tensile stresses. This results in the fractures in the hydroxyapatite (HA) crystals. It is also caused by the low packing density of the Hunter-Schreger band (HSB) at the cervical area. Unfortunately, there is a lack of evidence regarding the outcome of abfraction with or without intervention. The aim of this review is to collect clinical information from the literature and discuss the etiology, pathogenesis, clinical representation, and management. Also, search databases for clinical studies that describe the role of sclerotic dentine in non-carious cervical lesions (NCCLs) are becoming a cliNCCLs are better managed by a proper understanding of factors like etiopathogenesis, ultra-structure of enamel, and dentine and their effect on the bonding of restorations of the tooth.Background Dental caries is a dysbiotic polymicrobial disease that can cause damage to an individual's successful, elite sporting performance. Aims This study aimed to realize a meta-analysis to calculate a worldwide, pooled estimated prevalence of dental caries in athletes. Methods and materials This systematic review and meta-analysis was registered in PROSPERO (n° CRD42017068127). A systematic search was conducted in the electronic databases Pubmed, Scopus, Web of Science, Virtual Health Library (Lilacs) and Grey literature from inception up to April 2017. The MeSH terms "Sports," Athletes," and "Dental Caries" were used. The inclusion criteria used in this review were observational cross-sectional studies, longitudinal retrospective, and prospective studies that presented the prevalence of dental caries in athletes without intellectual disabilities. From selected articles, the risk of bias tools were assessed. After considering the qualitative heterogeneity among studies, a meta-analysis was conducted. Results A total of 1,376 abstracts were initially retrieved, with only five meeting the inclusion criteria. Of these, one was considered to have a low risk of bias and four were considered to have a moderate risk of bias. The overall estimated prevalence of dental caries in athletes was 46.25% (95%CI 28.73-64.27). Conclusion The estimated prevalence of dental caries in athletes, and particularly in athletes from developing countries is considered to be high. The pooled prevalence estimates have important implications in regard to preventive measures and research planning around the world.Context In-vitro studies of microleakage are an initial screening method to assess the maximum theoretical loss of sealing ability in-vivo. Aims Our objective was to determine and compare microleakage patterns of conventional glass ionomer cement (GIC) and resin-modified GIC (RMGIC) for band cementation. selleck chemical Methods Forty caries-free second primary molars were randomly divided into two groups of 20 teeth each. Preformed molar bands in the two groups were cemented to enamel with one of two types of cement Conventional GIC (Fuji I, GC Corporation; Tokyo, Japan) and RMGIC (Fuji Plus, GC Corporation; Tokyo, Japan). A dye penetration method was used for microleakage evaluation. Microleakage was determined by a stereomicroscope for the cement-band and cement-enamel interfaces. Statistical analysis used Statistical analysis was performed with Kruskal-Wallis and Mann-Whitney U tests. Results The mean microleakage value for conventional GIC (Fuji I) at cement-band and cement-enamel interfaces was 2.41 mm and 2.15 mm, respectively. The mean microleakage value for RMGIC (Fuji Plus) at cement-band and cement-enamel interfaces was 0.44 mm and 0.46 mm, respectively. Compared to conventional GIC, RMGIC showed less microleakage at both cement-band and cement-enamel interfaces. P less then 0.001 and it was statistically highly significant. Conclusions Bands cemented with RMGIC had significantly less microleakage between the cement-band and cement-enamel interfaces than conventional GIC.
