Dental caries: Dental caries and periodontitis were for many decades considered the most important global oral health burden. During the last 40 years when more focus was put on the prevention of dental caries by using products with fluoride, the problem decreased. However, our new lifestyle with more sugar has given rise to concern, and in US the amount of children being diagnosed with dental caries has increased [1]. In addition the increasing amount of elderly in the population using many different types of medicines giving dry mouth has a negative impact of the status of their teeth [2]...

Callithrix jacchus are small-bodied Neotropical primates popularly known as common marmosets. They are endemic to Northeast Brazil and occur in contrasting environments such as the humid Atlantic Forest and the dry scrub forest of the Caatinga. Common marmosets live in social groups, usually containing only one breeding pair. These primates have a parental care system in which individuals help by providing assistance to the infants even when they are not related to them. Free-ranging groups use relatively small home ranges (0...

Minimally invasive endodontics emphasizes preservation of a maximal amount of healthy tooth tissue. However, whether the tooth structure preserved by minimally invasive endodontics can maintain higher fracture resistance is unclear. This study aimed to compare the biomechanics on teeth after minimally invasive (MI) preparation and straight-line (SL) preparation using finite element analysis. Six finite element analysis models of a mandibular first molar were constructed and divided into two groups (MI and SL)...

INTRODUCTION: Pycnodysostosis is a rare genetic disease characterized by osteosclerosis and bone fragility. The clinical aspects are varied including short stature, acro-osteolysis of distal phalanges, and dysplasia of the clavicles. Oral and maxillofacial manifestations of this disease are very clear. The head is usually large, a beaked nose, obtuse mandibular angle, and both maxilla and mandible are hypoplastic. Dental abnormalities are common. We report a case with the typical clinical and radiological characteristics of the Pycnodysostosis associated with a conductive hearing loss, an association rarely reported...

Treatment of impacted dilacerated incisors is challenging for clinicians because of the prominent position of the teeth and the abnormality of their roots. We report on 2 patients who had horizontally upward impacted and severely dilacerated maxillary central incisors. The first patient's root perforated the labial plate without significant resorption, and the second patient's root was resorbed. Both patients were treated by a surgical-orthodontic approach, and the crowns of the impacted teeth were brought into the arches by closed forced eruption...

BACKGROUND/AIMS: Intermaxillary fixation is a standard procedure for the treatment of mandibular fractures or in orthognathic surgery. Pre-drilling for screws poses the risk of accidental tooth-root injury, potentially leading to further pathological processes. Limited evidence about accidental tooth injury during intermaxillary fixation is available due to heterogenous study designs. The aim of this study was to evaluate the risk of root trauma using pre-drilled transgingival fixation screws and the clinical consequences for the affected teeth...

Caries increment is affected by sugar-sweetened beverage (SSB) consumption. Taxing SSBs could reduce sugar consumption and caries increment. The authors aimed to estimate the impact of a 20% SSB sales tax on caries increment and associated treatment costs (as well as the resulting tax revenue) in the context of Germany. A model-based approach was taken, estimating the effects for the German population aged 14 to 79 y over a 10-y period. Taxation was assumed to affect beverage-associated sugar consumption via empirical demand elasticities...
