Foram avaliados 30 pacientes com idade entre 25 e 68 anos com profundidade à sondagem inicial d 6mm e = 8 mm nos sítios selecionados. Estes pacientes foram divididos em três grupos, cada um contendo 10 pessoas de acordo com o tratamento realizado: Grupo 1 - realização de raspagem e alisamento radiculares supra e subgengivais concomitantemente no mesmo dia; Grupo 2 - realização de raspagem alisamento e polimento supragengival e 7 dias após realização de raspagem e alisamento radiculares subgengival; Grupo 3 - realização de raspagem alisamento e polimento somente supragengival por 30 dias e complementação da raspagem subgengival após este período. Os pacientes foram avaliados antes e após 7, 15, 30 e 60 dias de realizado o procedimento inicial pelos seguintes parâmetros clínicos: profundidade de sondagem, nível de inserção, sangramento à sondagem, presença de placa, inflamação gengival e supuração. Também foram realizadas coletas de amostras de placa subgengival nos mesmos sítios e períodos e analisadas a prevalência e os níveis de 36 espécies bacterianas pela técnica do checkerboard DNA-DNA hybridization.

Subjects were monitored clinically and microbiologically prior and 7, 15, 30 and 60 days after this three periodontal treatments: Group 1 - concomitant supra and subgingival scaling and root planning; Group 2 - supragingival scaling 7 days prior to subgingival scaling and root planning; Group 3 - supragingival scaling 30 days prior to subgingival scaling and root planning. Clinical assessment of plaque, redness, suppuration, bleeding on probing, pocket depth and clinical attachment level were made in two anterior teeth per patient. Subgingival plaque samples were taken at the same sites and the presence and levels of 36 subgingival bacteria species were determined using checkerboard DNA-DNA hybridization. The mean levels and % colonized by each species (prevalence) was computed for each subject at each visit. As results of this study was verified that pocket depth was significantly reduced for group 1 and 2. The group that received only supragengival scaling until the 30th day didn't improve until this period, with a significant reduction after the complementation of subgengival scaling and root planning. The clinical attachment level parameter didn't demonstrate significant alteration in none of the three groups along the time. However all the groups showed improvement or stability in this parameter, tends the group 1 presented the best results, followed for the group 2 and 3, respectively.

No Association between Clinical Periodontal Conditions and Microbiological Findings on Driveline of Patients with Left-Ventricular Assist Devices (LVAD)

Schmalz, Gerhard, Zöbisch, Sven-Paul, Garbade, Jens, Rast, Josephine, Eisner, Mirjam, Wagner, Justus, Kottmann, Tanja, Binner, Christian, Eifert, Sandra, Ziebolz, Dirk 24 April 2023 (has links)
The aim of this retrospective study was to investigate whether there would be an association between periodontal disease parameters and positive bacterial findings at the driveline of patients with a left ventricular assist device (LVAD). Patients with an LVAD, who underwent a full oral and microbiological examination between 2016 and 2018, were included. During oral examination, periodontitis severity (stage and grade) and the periodontal inflamed surface area (PISA) were evaluated. A microbiological analysis was performed from swabs of the driveline, whereby different bacterial species were cultivated and analyzed. A total of 73 patients were included in the current study. The majority of participants (80.8%) had at least one positive bacterial finding during the study period. Most patients had a periodontitis stage of III-IV (80.9%). The determined PISA of the total group was 284.78 ± 352.29 mm2. No associations were found between the periodontal disease parameters and the bacterial findings in general, the bacterial findings on the day of oral examination or the bacterial findings 12 months prior to/after the oral examination (p > 0.05). Periodontitis is not associated with cultivated microbiological findings at the driveline of patients with an LVAD and thus appears not to be a risk indicator for driveline colonization. Nevertheless, the high periodontal burden in LVAD patients underlines the need for their improved periodontal care.
