Dental caries is an important public health problem worldwide. This study aims to prove how preventive therapies reduce the onset of caries in adult patients, and to identify patients with high or low risk of caries by using Classification and Regression Trees based survival analysis (survival CART). A clinical data set of 732 patients aged 20 to 64 years in nine Japanese general practices was ...

OBJECTIVE To determine an optimal treatment strategy for carious deciduous teeth. SETTING Manchester Dental Hospital. DESIGN Decision analysis. METHOD The likelihoods of each of the sequelae of caries in deciduous teeth were determined from the literature. The utility of the outcomes from non-treatment and treatment was then measured in 100 parents of children with caries, using a visual ...

While mutans streptococci have long been assumed to be the specific pathogen responsible for human dental caries, the concept of a complex dental caries-associated microbiota has received significant attention in recent years. Molecular analyses revealed the complexity of the microbiota with the predominance of Lactobacillus and Prevotella in carious dentine lesions. However, characterization o...

UNLABELLED There are several methods for identifying carious dentinal tissue aiming to avoid removal of healthy dentinal tissue. OBJECTIVES The purpose of this study was to test different methods for the detection of carious dentinal tissue regarding the amount of carious tissue removed and the remaining dentin microhardness after caries removal. MATERIAL AND METHODS The dentin surfaces of ...

The main aim of this study was to determine the susceptibility to photo-activated disinfection (PAD) of Streptococcus mutans when the organism was present in a collagen matrix--an environment similar to that which would exist within a carious tooth. In addition, the susceptibility to PAD of bacteria present in carious human teeth was also determined. Light was delivered to the collagen and teet...

OBJECTIVE To evaluate dentists' treatment choices for a crowned tooth with varying degrees of recurrent caries. MATERIALS AND METHODS A total of 158 dentists participated in the study. A paper patient case (PPC) depicting a radiograph showing varying degrees of recurrent caries at the crown margin was used: PPC1 = small carious lesion away from crown margin; PPC2 = small carious lesion at cro...

AIM Identification of potential carious risk criteria, retrospectively at 2 years of age, for developing carious lesions at 3 years of age. Study design Longitudinal observations from 2 until 3 years of age. Cross-sectional observations of two cohorts of 3- year-olds with different approaches. MATERIALS AND METHODS The study group consisted of 78 three- year- olds from a previous study at a...

This study investigated the influence of a papain-based gel (Papacárie) for chemo-mechanical caries removal on bond strength to dentin. Human molars were assigned to the following groups: Group 1: sound teeth were flattened to expose dentin; Group 2: after flattening of surfaces, the papain-based gel was applied on the sound dentin; Group 3: overlying enamel from carious teeth was removed and m...

Hybridized dentin permits dental treatments that were previously impossible with conventional techniques, opening new frontiers in modern adhesive dentistry. We have investigated the adhesive property of current bonding systems to caries-infected dentin by a microtensile bond strength test (µTBS) and transmission electron microscopy (TEM), and suggested that bonding resin could infiltrate into ...

An important issue prior to restorative or endodontic treatment of carious teeth is the assessment of the different conditions of each individual case. This relates to the static, anatomical considerations of the location of the caries lesion, as well as the dynamic activity and extent of the carious process. Moreover, the restorative treatment may be carried out for prosthetic or cosmetic purp...
