Abstract

Dental biofilm control represents a basic procedure to prevent caries and the occurrence of periodontal diseases. Currently, toothbrushes and dentifrices are used almost universally, and the employment of good oral hygiene allows for appropriate biofilm removal by both mechanical and chemical control. The aim of this study was to evaluate the effectiveness of adding vegetable or mineral oil to a commercially available dentifrice in dental biofilm control. A comparison using the Oral Hygiene Index Simplified (OHI-S) was performed in 30 individuals who were randomly divided into three groups. Group 1 (G1) received a commercially available dentifrice; the composition of this dentifrice was modified by addition of mineral oil (Nujol®) for group 2 (G2) or a vegetable oil (Alpha Care®) for group 3 (G3) at 10% of the total volume, respectively. The two-way repeated-measures analysis of variance (two-way ANOVA) was used to test the effect of group (G1, G2 and G3) or time (baseline, 45 days and 90 days) on the OHI-S index scores. Statistical analysis revealed a significant reduction in the OHI-S at day 90 in G2 (p < 0.05) and G3 (p < 0.0001) in comparison to G1. Therefore, the addition of a vegetable or a mineral oil to a commercially available dentifrice improved dental biofilm control, suggesting that these oils may aid in the prevention and/or control of caries and periodontal disease.

Highlights

Dental biofilm control is the primary aim in caries and periodontal disease prevention
The mean and standard deviation values of the Oral Hygiene Index Simplified (OHI-S) index scores in each evaluated group and time are illustrated in Figure 1 and are described as follows:
The statistical analysis demonstrated that the OHI-S index scores are affected by time (p < 0.0001) and by group (p = 0.0196)

Summary

Introduction

Dental biofilm control is the primary aim in caries and periodontal disease prevention. Mechanical removal of the biofilm, performed by appropriate use of toothbrush and dental floss, has been the main tool in oral hygiene care. There is a direct relationship between oral hygiene level, the quantity and quality of dental biofilm, and disease prevalence and severity. The prevalence of caries and periodontal disease among the population indicates that a significant number of individuals do not exhibit adequate biofilm control.[1]. Despite recognition of the effectiveness of mechanical biofilm control, the process may be potentialized by chemical control, especially in individuals at high risk to develop oral diseases.[5,6]
