RESUMO
O objetivo deste trabalho foi comparar os parâmetros clínicos periodontais após tratamento de defeitos infra-ósseos com retalho de espessura total (RET) associado ou não à proteína da matriz do esmalte (PME). Foram selecionados 10 pacientes com saúde geral boa, apresentando periodontite crônica e com um par ou mais de defeitos infra-ósseos (PCS ≥ 6 mm), totalizando 38 defeitos. Todos os pacientes receberam instruções de higiene bucal, raspagem e alisamento radicular, prévio a cirurgia. Foram divididos em dois grupos: grupo PME recebeu retalho de espessura total associado à proteína da matriz do esmalte; e o grupo RET recebeu apenas retalho de espessura total. Todos os pacientes passaram por sessões de controle e manutenção bucal a cada 3 meses, até o final do experimento. Após 24 meses observamos redução na média da PCS de 4,21 mm (PME) e 3,28 mm (RET), do início ao final do experimento, resultado significativo para ambos os grupos (p <0,001), entretanto, o PME mostrou redução da PCS estatisticamente superior ao RET, aos 24 meses (p = 0,030). Para o NCIR o ganho médio foi de 5,69 mm (PME)e de 5,24 mm (RET), sendo esses ganhos significativos para ambos os grupos (p <0,001) comparados o início ao final do experimento, no entanto, não houve diferença significativa quando comparadas às médias entre os dois grupos, ao final do trabalho (p = 0,59). Com relação ao IP, foi detectada uma redução significativa nos...
ABSTRACT
The aim of the present clinical trial was to compare the periodontal clinical parameters after the treatment of intrabony defects with open flap debridement (OFD) with or without enamel matrix derivative (EMD). Ten subjects with good health, chronic periodontite and one or more pair of the intrabony defects (PPD ≥ 6 mm), totalizing 38 defects. All the patients received instructions of buccal hygiene, scaling and root planning, previous surgery. They were divided into two groups: group PME received open flap debridement associated to the enamel matrix protein; and the group OFD just received open flap debridement. All the patients passed by control sessions and buccal maintenance every 3 months, until the experiment end. After 24 months, a mean reduction of PPD was 4,21 mm (EMD) and 3,28 mm (OFD), beginning at the end of the experiment, significant result for both groups (p < 0,001), however, EMD showed PPD reduction statistically superior to OFD, at 24 months (p= 0,030). For the relative attachment level (RAL) the mean gain was 5,69 mm (EMD) and 5,24 mm (OFD), being these significant for both groups (p < 0,001) compared the beginning at the end of the experiment, however, there was not significant difference when compared to the means between both groups, at the end of the work (p = 0,59). With regard to PI, it was detected a significant reduction in the two groups along the treatment (p=0,022 to EMD; P=0,005 to OFD), 60% to the group EMD and 80% to the group OFD, without however a statistically significant difference between groups be observed (p=0,46). When observed GI, so much in the EMD as in OFP, it was detected a significant reduction along the experiment (p<0,001), however...
