Resumo
Esse estudo teve como objetivo primário aplicar in loco Lactobacillus reuteri nas bolsas
periodontais verificando o possível ganho dos níveis de inserção clínica e diminuição bolsas
periodontais.Trata-se de um estudo clínico, randomizado, duplo-cego e boca dividida em que foram
triados noventa e dois pacientes e destes selecionados doze como unidade amostral para realização
do tratmento, nas Clínicas Odontológicas da Pontifícia Universidade Católica de Campinas Estes
pacientes foram randomizados e divididos em grupo teste (n=12) e controle (n=12). Por se tratar de um
estudo boca dividida foi realizado teste e controle em dentes homólogos do mesmo paciente. Além do
tratamento consagrado pela literatura, que é a raspagem e o alisamento radicular o paciente também foi
submetido a aplicação de um preparo contendo lactobacillus reuteri em um dente e seu homólogo na
arcada contrária recebeu o placebo. As medidas clínicas iniciais foram feitas por um avaliador cegado
ao estudo bem como as medidas clínicas após quarenta e cinco dias. Tempo necessário para formação
e renovação de fibras do ligamento periodontal. Além disso, o paciente não sabia em qual dente seria
aplicado o lactobacilo e qual seria o dente que receberia o placebo, pois, estes foram escolhidos por
sorteio. Ao observar os dados percebeu-se que nos casos controle as médias das medidas iniciais foram
de 5,17mm e as medidas finais de 3,83mm, correspondendo a uma diferença de 3,83mm, ou seja, houve
uma redução na profundidade de sondagem. A utilização do Lactobacillus reuteri aplicados in loco para
diminuição da inflamação na bolsa periodontal e consequentemetne, a diminuição da profundidade de
sondagem e ganho deinserção clínica pode ser utilizada como coadjuvante ao tratamento padrão ouro
ja estabelecido. No entanto, há necessidade de mais estudos para demonstração das vantagens da
administração in loco
This study's primary objective was to apply Lactobacillus reuteri in situ to periodontal pockets, verifying the possible gain in clinical attachment levels and reduction of periodontal pockets. This is a randomized, double-blind, split-mouth clinical study in which ninety-eight two patients and of these twelve were selected as sampling units to carry out the treatment, at the Dental Clinics of the Pontifical Catholic University of Campinas. These patients were randomized and divided into a test group (n = 12) and control group (n = 12). As this was a split mouth study, test and control treatment was carried out on homologous teeth from the same patient. . In addition to the treatment recognized in the literature, which is scaling and root planing, the patient was also subjected to the application of a preparation containing lactobacillus reuteri in one tooth and its counterpart in the arch received the placebo. Initial clinical measurements were taken by an evaluator blind to the study as well as clinical measurements after forty-five days. Time required for formation and renewal of periodontal ligament fibers. Furthermore, the patient did not know which tooth the lactobacillus would be applied to and which tooth would receive the placebo, as these were chosen by draw. When observing the data, it was noticed that in the control cases the average initial measurements were 5.17mm and the final measurements were 3.83mm, corresponding to a difference of 3.83mm, that is, there was a reduction in the probing depth. The use of Lactobacillus reuteri applied in situ to reduce inflammation in the periodontal pocket and consequently, reduce probing depth and gain clinical attachment can be used as an adjunct to the already established gold standard treatment. However, there is a need for more studies to demonstrate the advantages of on-site administration
