Atsushi Oishi
This case report describes the importance of continual examination for dental trauma and the efficacy of intentional replantation with retrograde root canal filling for a transverse root fracture in an immature incisor accompanied by subsequent periodontal-endodontic disease. In the treatment of traumatically fractured roots in immature incisors, continual examination is indispensable for the final diagnosis because roots in immature teeth are less calcified, resulting in less detailed radiological examinations...

Too many children develop carious lesions and many such lesions progress into a dentine carious lesion. In 2010, the percentage of dentine carious lesions in the primary dentition of 6-year-old Dutch children that were restored was less than 50 per cent. Owing to research, the necessity to restore dentine carious lesions routinely has been called into question. Current understanding of cariologic principles point in the direction of a causal treatment that is based on cleaning accessible dentine carious cavities and those that can be made accessible, possibly supported by the application of silver diamine fluoride...

Lateral and apical ramifications of the main root canal create potential pathways through which bacteria can spread and remain unaffected by treatment procedures. It is a challenge for the specialty to find techniques that can predictably reach, disinfect, and obturate these ramifications. Here, we report the use of a novel instrumentation approach to aid in the negotiation and management of a lateral canal discernible on cone-beam computed tomography (CBCT) in an unusual maxillary central incisor. A 23-year-old female patient was referred for evaluation and possible treatment of tooth 9...

Background. One of the problems with composite resin restorations is gap formation at resin‒tooth interface. The present study evaluated the effect of preheating cycles of silorane- and dimethacrylate-based composite resins on gap formation at the gingival margins of Class V restorations. Methods. In this in vitro study, standard Class V cavities were prepared on the buccal surfaces of 48 bovine incisors. For restorative procedure, the samples were randomly divided into 2 groups based on the type of composite resin (group 1: di-methacrylate composite [Filtek Z250]; group 2: silorane composite [Filtek P90]) and each group was randomly divided into 2 subgroups based on the composite temperature (A: room temperature; B: after 40 preheating cycles up to 55°C)...

Streptococcus mutans is the primary agent of dental cavities, in large part due to its ability to adhere to teeth and create a molecular scaffold of glucan polysaccharides on the tooth surface. Disrupting the architecture of S. mutans biofilms could help undermine the establishment of biofilm communities that cause cavities and tooth decay. Here we present a synthetic peptide P1, derived from a tick antifreeze protein, which significantly reduces S. mutans biofilm formation. Incubating cells with this peptide decreased biofilm biomass by approximately 75% in both a crystal violet microplate assay and an in vitro tooth model using saliva-coated hydroxyapatite discs...

Surgical extraction of teeth due to dental pathologies is a relatively common procedure in modern man. The healing of the wound that results occurs in gradual and sequential stages, such that the analysis of this repair process can be very useful in forensic investigations on human remains. The following study reports on a particular case where the remodeling of a tooth socket allowed an estimation of the time that had elapsed from the day of the surgical extraction of the tooth to the time of death. The corpse was that of a woman of 34 years...

Objectives If children in formative stages ingest foods that are too hard or too soft, they can experience delays in oral cavity functions. Therefore, it is important for young children to receive foods of appropriate hardness in relation to their chewing ability. We investigated the relationship between the ingestion of 15 different food items and tooth eruption among children aged 18-20 months.Methods Caregivers from Japanese municipalities who took their children for an 18-month health check-up were given an anonymous questionnaire...

REVIEW
Glendee Reynolds-Campbell, Alison Nicholson, Camille-Ann Thoms-Rodriguez
The human oral cavity contains more than 500 different bacterial species. These organisms belong to several phyla including Bacteroidetes, Firmicutes, Tenericutes, Actinobacteria, Proteobacteria, Euryarchaeota, Chlamydiae, and Spirochaetes. Many of these have the ability to colonize the gingival crevices and the outer surface of the tooth forming biofilms often leading to dental plaque formation. These bacteria produce acid that erode teeth causing cavities or infections. The diagnosis of these infections is often clinical and antibiotics are used empirically to treat some infections or as prophylaxis...

The application of the Glass Ionomer Cements in clinical dentistry is recommended due to properties such as fluoride release, chemical adhesion to tooth, negligible setting shrinkage, and coefficient of thermal expansion close to tooth, low creep, and good color stability. However, the cement is vulnerable to early exposure to moisture due to slow setting characteristics. The uses of external energy such as ultrasound and radiant heat (Thermo-curing) have been reported to provide acceleration of the setting chemistry and enhance physical properties...
