OBJECTIVES To assess the impact of oral health on the life quality of a periodontal patient group. MATERIALS AND METHODS Two hundred and five patients attending a private periodontal clinic completed a questionnaire incorporating the 16-item UK oral health-related quality-of-life measure (OHQoL-UK), a check list of questions about their periodontal health(More)
The effect of metronidazole was assessed in 20 subjects with untreated periodontitis, in a double-blind trial. Subjects received a 1-week course of drug or placebo immediately after baseline examination, and were reassessed 1 month and 3 months later. A 0.25 N constant force probe and darkfield microscopy were used. At 1 month, a difference was observed(More)
A new design of single tooth implant (AstraTech, Molndal Sweden) featuring a microthreaded conical neck and TiO blast surface was evaluated clinically and radiographically after 2 years in function. Fifteen patients (age range 16 to 48) with missing maxillary anterior teeth (6 central incisors, 8 laterals, 1 bicuspid) had 4, 13 mm and 11, 15 mm implants(More)
The aim of this survey was to study the prevalence of juvenile periodontitis in schoolchildren aged 12-19 yr in Lagos, Nigeria. 1001 children, 565 boys and 436 girls, took part in the study. Initially all the children were screened clinically at school according to the recommendations of CPITN. A mirror and WHO 621 pattern probe were used for this(More)
Immunocytochemical analysis was carried out on samples of 5-, 6-, and 9-week old regenerated soft tissue taken from healing periodontal defects treated by guided tissue regeneration using expanded polytetrafluorethylene (ePTFE) membranes. A panel of monoclonal and polyconal antibodies to cytokeratins, vimentin, and collagen was used to label cells and(More)
The aim of the present study was to compare guided tissue regeneration with conventional surgery in matched periodontal defects within the same subject. Twenty pairs of sites in nine subjects were treated. Surgery was performed at both test and control sites on the same visit. Random allocation was not performed until all preparation and root(More)
In an attempt to determine the usefulness of evoked potentials as a measure of focal cerebral ischemia, we examined somatosensory evoked potentials (SEP's) and morphological neuronal changes in cats following unilateral middle cerebral artery (MCA) occlusion. Fifteen adult cats underwent transorbital occlusion of the MCA under halothane anesthesia. In seven(More)
Bone augmentation around implant fixtures using the technique of guided tissue regeneration has been described in a number of reports. The aim of this study was to evaluate bone fill around dehiscence defects at matched defects randomly allocated to test (expanded polytetrafluoroethylene; Gore-Tex) or control treatments within the same patient. Six(More)
The purpose of this study was to monitor clinical attachment levels, using a constant force probe, in patients with untreated periodontal disease, and to use darkfield microscopy to monitor changes in subgingival plaque. 10 patients with untreated disease were studied over 12 weeks. The parameters measured at baseline and every 4 weeks were probing depth,(More)
