Abstract

Objectives: Dental biofilm consists of bacterial communities which reside in dental surface and soft tissue, being considered the main etiological factor for periodontal disease. Its regular removal is, therefore, essential and has been a pillar for maintenance of oral health and prevention of oral disease. The aim of this study was to assess the efficacy of an oral irrigator (Waterpik®- USA) in oral hygiene associated with the conventional method (CM) (Bass tooth brushing technique and dental floss) through O’Leary’s Plaque Index (PI).
Methods: Twenty volunteers, aged 18-50 years old, with plaque index (PI) higher than 20% participated in this randomized study. They were divided into two groups: G1 - CM, G2–CM associated with an oral irrigator, once a day. PI was collected on baseline and after 15 days. After that, there was a washout period of 15 days. In the second part of the study, volunteers changed the groups of research. The last PI was performed 30 days after the second PI.
Results: It was found that Waterpik® in association with conventional method did not significantly reduce the PI (p=0.177) when compared to conventional method alone. Regarding initial PI, conventional method, when associated or not with Waterpik®, reduced significantly PI (p<0.001).
Conclusions: The oral irrigator did not enhance the biofilm removal, not behaving as an efficient and reliable complementing conventional oral hygiene

Introduction

Dental biofilm consists of bacterial communities which reside in dental surfaces and soft tissue and present important role on oral disease. Regular biofilm removal is, therefore, essential and has been a pillar for maintenance of oral health and prevention of oral disease (Marsh, 2005) [1]. The most widespread and consolidated form of biofilm removal is tooth brushing (Axelsson et al., 2004). This method effectively removes biofilm on the buccal and palatal/lingual faces of the teeth, although it is not as effective in the interproximal area (Hotta et al., 2009). The interdental area is more susceptible to periodontal disease, becoming important the adoption of complementary methods for biofilm removal in this area. The use of dental tape or floss is the most common way of interproximal cleaning (Reitman et al, 1980; Kinane et al, 1992), but depends on the manual dexterity, as well as patient’s motivation and compliance.
