Inhibition of dentine collagen degradation by hesperidin: an in situ study.

Dentine caries is a process of demineralization and subsequent degradation of the collagenous matrix. Host-derived proteolytic enzymes, such as matrix metalloproteinases (MMPs), play a role in this process of dentine collagen degradation. Hampering this degradation retards the caries process.

Comparative study of the measurement of enamel demineralization and remineralization using transverse microradiography and electron probe microanalysis.

Transverse microradiography (TMR) and electron probe microanalysis (EPMA) are commonly used for characterizing dental tissues. TMR utilizes an approximately monochromatic X-ray beam to determine the mass attenuation of the sample, which is converted to volume percent mineral (vol%min). An EPMA stimulates the emission of characteristic X-rays from a variable volume of sample (dependent on density) to provide compositional information.

Cessation age of breast-feeding and pacifier use is associated with persistent finger-sucking.

Purpose: Although some studies have reported that breast-feeding and pacifier use influence finger-sucking, few have demonstrated whether the age at cessation of breast-feeding or pacifier use and persistent finger-sucking are related. Therefore, the purpose of this study was to examine whether the age at cessation of breast-feeding and pacifier use influenced persistent finger-sucking.

Methods: A cross-sectional study of 555 36- to 47-month-olds was conducted in Nagasaki, Japan, using a questionnaire.

Effect of bamboo salt-NaF dentifrice on enamel remineralization.

Purpose: To evaluate the laboratory remineralization effects of a dentifrice with bamboo salt and NaF on artificial caries-like enamel lesions, at both the surface and deep areas.

Methods: Early dental caries lesions were formed by treating bovine enamel samples for 48 hours at 37 degrees C with a demineralization solution (pH 5.0) containing 0.

Dental caries in 3-year-old children is associated more with child-rearing behaviors than mother-related health behaviors.

Objective: We assessed whether child- or mother-related health behaviors were associated more strongly with dental caries in 3-year-old children.

Methods: Multiple logistic regression analyses were performed on dental caries' presence as the dependent variable with independent variables from the results of examination and a self-administered questionnaire of 396 mother-child pairs.

Result: Dental caries of 3-year-old children was more strongly associated with child-related health behavior than mother-related health behavior.

Enamel fluoride uptake from mouthrinse solutions with different NaF concentrations.

Objectives: The influence on enamel fluoride uptake of reducing the NaF concentration of a mouthrinse solution by half, from 0.05-0.025%, was examined in elementary school children.
