Ten-year survival of ART restorations in permanent posterior teeth
This study evaluated the 10-year clinical performance of high-viscosity glass-ionomer cement placed in posterior permanent
teeth by means of the Atraumatic Restorative Treatment (ART) approach. One operator placed 167 single- and 107 multiple-surface
restorations in 43 high-risk caries pregnant women (mean decayed teeth = 9.8 ± 5.5). Examinations were performed at 1-, 2-,
and 10-year intervals according to ART criteria. In the last evaluation, the US Public Health Service (USPHS) criteria were
also used. After 10 years, 129 restorations (47.1%) were evaluated and achieved a cumulative survival rate of 49.0% (SE 7.2%).
The 10-year survival of single- and multiple-surface ART restorations assessed using the ART criteria were 65.2% (SE 7.3%)
and 30.6% (SE 9.9%), respective......

Safer Hip, Knee And Dental Implants With Smart Coating
Researchers at North Carolina State University have developed a "smart coating" that helps surgical implants bond more closely with bone and ward off infection. When patients have hip, knee or dental replacement surgery, they run the risk of having their bodies reject the implant. But the smart coating developed at NC State mitigates that risk by fostering bone growth into the implant... (Source: Dentistry News From Medical News Today)...

Assessment of traumatic injuries to primary teeth in general practise and specialized paediatric dentistry
Conclusions: The group referred for specialist treatment had more severe injuries and needed more complicated treatment than the group recommended for care by general dentists. However, the rate of sequelae in permanent successors was the same in both. (Source: Dental Traumatology)...

Fracture resistance and reinforcement of immature roots with gutta percha, mineral trioxide aggregate and calcium phosphate bone cement: a standardized in vitro model
In this study, an experimental model was developed to determine the fracture resistance of immature teeth and to test the hypothesis that endodontic materials succeed in reinforcing them. Compact and hollow bone cylinders from bovine femurs were used as standardized samples. In order to evaluate the experimental model, fracture resistance in both groups was evaluated by determining the ultimate force to fracture (UFF) under diametral tensile stress. Analysis of variance (ANOVA) revealed a statistically significant difference between the mean values of UFF for both groups, independently of the sampling location or subject. In a following setting, the hypothesis that obturation with gutta percha (GP), mineral trioxide aggregate (MTA), or calcium phosphate bone cement (CPBC) reinforces the ho......

Eighth Annual 'Give Kids A Smile' Day Provides Free Dental Care To Children
With an economy that might cause some parents to postpone regular dental visits for their children and tooth decay being the most prevalent chronic disease in America's children, the American Dental Association (ADA) is mobilizing dental professionals for the eighth consecutive year in a national campaign to extend necessary care to children and adolescents from low-income families...

Mesiodistal angulations of the mandibular canines, premolars and molars with or without the presence of third molars.
Authors: Cuoghi OA, Sella RC, de Mendonça MR
The purpose of the present research was to compare the normal average values of mesiodistal axial angulation, with the mesiodistal axial angulation of canines, premolars and mandibular molars in individuals with and without the presence of the mandibular third molars. Panoramic radiographs of 19 male and 21 female Caucasians, with a mean age of 22.35 years, who had not undergone orthodontic treatment were studied. The subjects were divided into two groups: group I, 20 radiographs of subjects without, and group II, 20 radiographs of subjects with mandibular third molars. The mean values of the groups were compared using a Student's t-test. The results show that, in both groups, the mandibular premolars and molars had enhanced angulation ......

Regenerative Treatment of Peri-Implantitis Bone Defects with a Combination of Autologous Bone and a Demineralized Xenogenic Bone Graft: A Series of 36 Defects
Conclusion: Within the limits of the study, we conclude that for bone defects larger than 4 mm in case of peri-implantitis, this single surgical intervention provided a reliable method to reduce bone defects. (Source: Clinical Implant Dentistry and Related Research)...

Dentinogenic potential of the dental pulp: facts and hypotheses
The aim of the present article is to discuss observations and hypotheses from different experimental approaches on the biological mechanisms underlying initiation of tertiary dentin formation and therapeutic control of pulp[ndash]dentinal regeneration. The specific dentinogenic potential of dental pulp cells in up-regulating the biosynthetic activity of primary odontoblasts (reactionary dentinogenesis) and differentiation into odontoblast-like cells (reparative dentinogenesis) is described. The role of biologically active matrices and molecules as signaling factors in the expression of the dentinogenic potential of dental pulp cells, in numerous ex vivo and in vivo models, is reviewed. Data are focused on the mechanisms by which the signaling molecules, in the presence of the appropriate p......

Inflammatory nerve responses in the dental pulp
Tooth pulp has a dense innervation and a rich vascular supply to maintain homeostasis and to preserve the integrity of the tissue. Function, trauma, and antigenic challenges make teeth and supporting tissues susceptible to tissue injury and inflammation, partially due to the lack of collateral blood and nerve supply and to their low compliance. This review focuses on dental nerve functions and adaptive changes in the pulpal nerve supply following inflammation and peripheral injury. Overviews of dental innervation and its development and of the peptidergic innervation of oral tissues are presented, followed by a discussion of peripheral and central changes after local insults to teeth and peripheral nerve injuries. The functional implications of these adaptive changes are considered.Receive......

Circulation in normal and inflamed dental pulp
In the pulp, arteries branch into a capillary network before they leave the pulp as venules through the apical foramina. The tissue has low compliance, as it is enclosed in dentin, and has a relatively high blood flow and blood volume. The interstitial fluid pressure (IFP) and colloid osmotic pressure are relatively high whereas the net driving blood pressure is low. The high pulsatile IFP is probably the major force for propelling lymph in the dental pulp. Vasodilation in neighboring tissue as well as arteriovenous (AV) shunts in the pulp itself can contribute to a fall in total and coronal pulpal blood flow, respectively. The pulp blood flow is under nervous, humoral, and local control. Inflammatory vascular responses, vasodilation, and increased vessel permeability induce an increase in......
