Correlation between interleukin-1β and matrix metalloproteinase-1 levels in crevicular fluid with a proposed periodontal disease index in children.

Background: The crevicular fluid contains biomarkers that allow the identification of periodontal disease, anticipation of its risk, and prediction of its progression.

Purpose: The purpose of this study is to correlate interleukin-1β (IL-1β) and matrix metalloproteinase-1 (MMP-1) levels in crevicular fluid with periodontal disease severity in schoolchildren.

Methods: A cross-sectional study was conducted in 82 schoolchildren between 9 and 12 years.

A parent motivational interviewing program for dental care in children of a rural population.

Objectives: To determine the effectiveness of a motivational interviewing-based educational program in reducing the number and intensity of new caries and bacterial dental plaque levels at 6 months post randomization.

Study Design: A randomized and single blind clinical trial in 100 schoolchildren between 6-10 years of age presenting the highest risk score of caries according to the Caries Management by Risk Assessment (CAMBRA) criteria was performed. These patients were randomized to two groups: control (in which the mothers initially received an oral prevention informative session) and experimental (in which the mothers received the initial informative session, followed by individual motivational interviewing sessions during a period of 6 months).
