Standard protocols for the clinical use of dental implants often include placement healing abutments prior to standard or custom-made abutments. The tissue response a single shift from abutment permanent has not been studied.The aim present experiment was study reactions that may occur following removal and abutment.In six beagle dogs, all mandibular premolars were extracted. Three months later three fixtures Astra Tech Implants Dental System (Astra AB, Mölndal, Sweden) installed in each...
ABSTRACT Aim This study aimed to create an objective assessment system for evaluating gingival tissue generated in a rat model using representative free graft (FGG). Methods A defect (2 × 2 mm) created on the mandibular anterior teeth of rats was evaluated its application as recession after 4 weeks. Using this model, we investigated validity method reconstruction at FGG site. Gingival margin heights normal and transplanted gingiva were compared, pockets visualized computed tomography (CT)....
To determine microbial changes that occur during plaque formation in a dentition free of gingival inflammation.Ten subjects were recruited. The study included one preparatory period (2 weeks) and accumulation (4 days). volunteers exercised proper tooth cleaning methods, scaled received repeated professional mechanical the period. During period, participants abstained from control measures. Plaque was scored on approximal surfaces maxillary mandibular premolars Days 0, 1, 2 4 using scale 0 to...
Periodontal disease is assessed and its progression determined via observations on a site-by-site basis. data are complex structured in multiple levels; thus, applying summary statistical approach (i.e., the mean) for site-level evaluations results loss of information. Previous studies have shown availability mixed effects modeling. However, clinically beneficial information periodontal during follow-up period not available. We conducted multicenter prospective cohort study. Using modeling,...
Background and Objective A diagnosis of periodontitis progression is presently limited to clinical parameters such as attachment loss radiographic imaging. The aim this multicenter study was monitor disease in patients with chronic during a 24‐mo follow‐up program evaluate the amount bacteria saliva corresponding IgG titers serum for determining diagnostic usefulness each indicating stability. Material Methods total 163 who received trimonthly care were observed 24 mo. salivary content...
Abstract Aim: The aim of the present experiment was to study effect different chlorhexidine regimens on number bacteria in saliva, and de novo plaque formation. Material Methods: Ten subjects with gingivitis, but no signs destructive periodontitis, were recruited. Following a screening examination, volunteers given oral hygiene instruction, meticulous scaling professional mechanical tooth cleaning (PTC). PTC repeated once every 3 days during 2‐week period establish healthy gingival...
Abstract Objective: To evaluate the effect of a pretreatment regimen that combined meticulous mechanical tooth cleaning with daily use chlorhexidine (rinse, gargle and tongue application) on de novo plaque formation recolonization various microbiological species in saliva during 4‐day period no oral hygiene. Material Methods: Ten subjects aged 24–36 years gingivitis were recruited. The study was designed as double blind cross‐over clinical trial including two phases. Each experimental phase...
Abstract Background: The clinical effect of Listerine ® , a mouth rinse containing mixture phenolic compounds, is ascribed to its bactericidal properties. However, compounds are also known interfere with the inflammatory process. Objective: purpose this trial was evaluate regular rinsing on plaque and gingivitis during 2‐week period no mechanical oral hygiene. Material Methods: Twenty‐one subjects were recruited for study. On Day 0 each experimental period, participants told abstain from all...
The diagnosis of the progression periodontitis presently depends on use clinical symptoms (such as attachment loss) and radiographic imaging. aim multicenter study described here was to evaluate diagnostic bacterial content subgingival plaque recovered from deepest pockets in assessing disease chronic patients. This consisted a 24-month investigation total 163 patients with who received trimonthly follow-up care. Subgingival assessed for Porphyromonas gingivalis, Prevotella intermedia,...
Abstract Objective: To investigate the impact of bonded mandibular orthodontic retainers on local periodontal health. Methods: Two groups subjects were recruited and designated Group F+, individuals who provided with a fixed wire lingual retainer in anterior area following treatment F−, no clear sign malalignment. A clinical examination, biochemical analysis, bacteriological analysis performed at commencement baseline (BL) 1 week (T1), 4 weeks (T2), 8 (T3) placement. The vertical position...
Probing depth (PD) and bleeding on probing (BOP) are essential clinical parameters used for periodontal diagnosis. This study investigated whether detection of hemoglobin (Hb) in gingival crevicular fluid (GCF), along with PD BOP, would improve diagnostic accuracy.After plaque index (PI) was measured, GCF collected from the sulci 401 anterior teeth maxilla mandible 184 patients who had entered maintenance therapy. Clinical (gingival [GI], PD, attachment level [CAL], BOP) were recorded. Hb...
Abstract Background: Studies in humans have indicated that systemically administered flurbiprofen and ibuprofen may reduce gingivitis. De novo plaque formation is enhanced at tooth surfaces adjacent to inflamed gingivae. Objective: The aim of the present clinical trial was evaluate effect systemic administration on gingivitis build‐up. Material Methods: Eleven subjects were recruited for study given oral hygiene instruction, scaling professional mechanical cleaning (PTC). At end a...
Abstract Background To date, a few studies have documented the detailed periodontal conditions of Japanese population. It is important to know if awareness nationals and dentists regarding oral hygiene prevention disease improved when compared with past in Japan for development future scenarios prevention. The aim this study was investigate severity, prevalence, extent adult population city Takahagi, Japan. Results were also those an epidemiological performed 1980s. Methods A total 582 (aged...
The periodontal inflamed surface area (PISA) is a useful index for clinical and epidemiological assessments, since it can represent the inflammation status of patients in one contentious variable. However, calculation PISA difficult, requiring six point probing depth measurements with or without bleeding on 28 teeth, followed by data input program. More simple methods are essential screening disease studies. In this study, we tried to establish convenient partial examination method estimate...
Periodontal disease is a chronic inflammatory of the periodontal tissue. The inflamed surface area (PISA) proposed index for quantifying burden resulting from periodontitis lesions. This study aimed to investigate longitudinal changes in status as evaluated by PISA following active treatment. To elucidate prognostic factors PISA, mixed-effect modeling was performed clinical parameters, tooth-type, and levels pathogens independent variables. One-hundred-twenty-five patients with who completed...
