Abstract. This survey investigated the association between efficacy of plaque removal and toothbrushing forces during a normal brushing regime. The 94 subjects participating in this study were requested not to brush 24 h prior experiment. Panellists brushed for 1 min with manual toothbrush. Before after brushing, was assessed using Turesky modification Quigley & Hein index. A second 1‐min exercise carried out assess force. mean reduction 39%, vestibular surfaces being cleaned most...
Abstract. The aims of the present study were: (1) to establish incidence gingival abrasion as a result toothbrushing. using manual and electric toothbrush: (2) influence filament end‐rounding on efficacy toothbrushing: (3) assess whether speed brush has feedback‐effect brushing force used correlate with force. 2 experiments were earned out. In first experiment, 50 subjects brushed for 3 weeks every other day either (Butler 411) or an toothbrush (Braun/Oral‐B Ultra Plaque Remover‐D9). All...
The prevalence of selected putative periodontal pathogens colonizing oral mucous membranes was investigated in 26 denture-wearing subjects with a history periodontitis. microbiota the cavity these examined on average 9.3 years after extraction (range: 1-40 years). Samples were taken from several locations membranes, saliva and plaque attached to upper lower denture. Actinobacillus actinomycetemcomitans not detected any edentulous subjects. Porphyromonas gingivalis 2 (proportion cultivable...
The present study was designed to evaluate if different periods of supervised oral hygiene prior the experimental gingivitis trial have an effect on amount inflammation which develops in 'toothshield' model. Two groups were compared. One group (Group A) over a 5-month period before gingivitis. Six months later Group A participated second trial, this time receiving only 1-month pretrial. B) served as control pre-trial start phase. During all subjects undertook regime vigorous included...
The purpose of the present study was to examine composition oral microbiota in subjects who had previously demonstrated develop either a weak or strong response experimental gingivitis. For this study, were selected from pool 25 individuals participated twice an gingivitis trial. Out these panellists, 6 developed 2X gingival inflammatory and 7 response. Approximately 9 months after 2nd trial, we evaluated clinical condition prevalence panel micro-organisms subjects. clinically examined for...
