e o final do estudo com relação à sangramento à sondagem e
profundidade de bolsa à sondagem tanto no grupo controle
nas bolsas rasas, moderadas e profundas (estratificações 1-4
mm; 5-6 mm; e ≥7 mm) quanto no grupo teste nas bolsas
rasas e profundas (estratificações 1-4 mm; e ≥7 mm). Ou
seja, os dois tratamentos foram igualmente eficazes nestes
parâmetros, embora sem diferenças entre si.
No presente estudo, a terapia básica periodontal não
cirúrgica convencional apresentou os mesmos resultados
do que quando combinada com a terapia fotodinâmica,
em pacientes com periodontite agressiva. Para confirmação
desses resultados encontrados, novos estudos clínicos
randomizados controlados com amostras mais significativas
e com tempos maiores de observação são necessários.
CONCLUSÃO
No presente estudo tanto a terapia periodontal
convencional quanto a associada a PDT apresentaram
melhora dos parâmetros clínicos após três meses de
tratamento. No entanto, não foram encontradas diferenças
significativas entre os grupos teste e controle.
Estudos com uma amostra maior e com maior tempo de
acompanhamento devem ser realizados para se verificar o
efeito da terapia fotodinâmica como adjunto do tratamento
da periodontite agressiva.
ABSTRACT
Aggressive periodontitis is an inflammatory process of
bacterial origin mediated by host immune response and is
probably the most serious form of periodontal disease, with
destruction of the structures of protection and support, with
fast course, often leading to premature loss of the teeth. The
aim of this randomized controlled trial was to investigate
the clinical effect of photodynamic therapy as an adjunct to
nonsurgical periodontal treatment in patients with aggressive
periodontitis. We selected ten patients with aggressive
periodontitis, which were examined in the baseline to three
months. The study design consisted of a split mouth model,
where a quadrant was treated with scaling and root planing
and photodynamic therapy (diode laser) and the other only
with scaling and root planing. Three months after the end of
the treatment, the treatment groups showed similar results
for all clinical parameters evaluated: both therapies have
been successful and showed reduction of pocket depth,
gain of relative attachment level, reduction of visible plaque
index, reduction of bleeding on probing, decreased furcation
involvement and decreased mobility, but without statistically
significant differences between them. The results suggest that
photodynamic therapy adjunct to non-surgical periodontal
mechanic treatment was as effective as the non-surgical
periodontal mechanic treatment alone.
UNITERMS: photosensitizing agents, photodynamic
therapy, aggressive periodontitis, laser.
