Resumo
The use of Nd:Yag laser for bacterial reduction as an adjuvant to
nonsurgical periodontal treatment has been approached in several
studies. Furcation complex anatomy is responsible for comprised
treatment results in this areas due to the lack of proper
access for instrumentation showing the persistence of a pathogenic
microbial flora. The purpose of this clinical trial, randomized,
double-blinded was to evaluated the bacterial reduction achieved
with the Nd:YAG associated to conventional treatment on furcation
sites of patients with chronic periodontitis. In a split mouth
design study, 34 class II furcations that were selected from 17
patients with chronic periodontitis. They received previous full
mouth periodontal treatment, except for the experimental sites.
The 17 furcations of the Control group underwent twice manual
and ultrasonic root debridment in weekly intervals. The Test
group received the same treatment as the Control group followed
by the Nd:YAG laser application (100mJ/pulse; 1.5W; 15Hz;
60sec). The microbiological parameters total numbers of anaerobic
Colony Forming Units(CFU); Black pigmented CFU and the
level of Actinobacillus actinomycetemcomitans(Aa), Porphyromonas
gingivalis (Pg) and Prevotella intermedia(Pi) were determined
at baseline, immediatly and one month after the treatment.
The results showed a significant reduction of total CFU for both
groups immediately after the treatment, but it was better for the
Test group. After one month the total CFU average increased but was still below pretreatment levels for both groups. The black
pigmented CFU and the level of Aa, Pg e Pi decreased significantly
after the treatment but 30 days after there was an increase
almost equal to baseline levels for both groups. The Nd:Yag laser
associated with convencional treatment promoted bacterial
reduction on class II furcation immediately after its application.
