The aim of this retrospective study was to record patients' satisfaction with fixed metal ceramic bridges and crowns made by dental students and to evaluate the functioning and condition of the bridges and crowns clinically and radiologically. Out of the 60 patients treated at the Institute of Dentistry during 1984-85, 30 patients attended the follow-up examination (16 women, mean age 39, range 23-62 years and 14 men, mean age 44, range 26-65 years). The anamnestic data and data regarding treatment procedures were collected from the patient files. The patients had been supplied with 41 crowns and 24 bridges (mean 3.9 units, range 3-6 units), which included 61 abutments and 33 pontics or cantilever extensions (abutment/pontic ratio 1.85: 1). Marginal fidelity was unsatisfactory in 13% of the crowns and bridges and gingival bleeding and pockets of 4-6 mm were noted in 27% and 12% of cases, respectively. None of the subjects had caries in the abutments.
Eating disorders are often associated with regurgitation of gastric contents into the mouth and dental erosion. In this study the dental status was evaluated in bulimic patients. Thirty-five bulimics, diagnosed in the Outpatient Departments of Psychiatry and Adolescent Psychiatry of the University Central Hospital in Helsinki, and 105 controls matched for age, sex, and educational level were examined clinically, and the factors associated with dental erosion and caries were evaluated in an interview. Severe dental erosion and dental caries were significantly commoner among bulimics than controls. Bulimics commonly had a low salivary flow rate, but other apparent risk factors of dental erosion did not differ from those of controls. A feeling of dry mouth was commoner among bulimics than controls, and bulimics had an increased tooth sensitivity to cold and touch. More should be done to protect teeth from dental erosion among bulimics, because loss of tooth tissue remains even if the eating disorder disappears.
Gingival health (bleeding on probing) and oral hygiene (plaque percent) were assessed in 2 groups of children and adolescents with insulin-dependent diabetes mellitus (IDDM). 1st study group included 12 newly diagnosed diabetic children and adolescents (age range 6.3-14.0 years, 5 boys and 7 girls). They were examined on the 3rd day after initial hospital admission and at 2 weeks and 6 weeks after initiation of insulin treatment. Gingival bleeding decreased after 2 weeks of insulin treatment (37.8% versus 19.0%, p
OBJECTIVE: The aim of the present study was to describe some clinical periodontal features of partially edentulous patients referred for the treatment of peri-implantitis. MATERIAL AND METHODS: The 23 subjects involved in this study were selected from consecutive patients referred to the department of Periodontology Södra Alvsborgs Hospital, Borås, Sweden, for treatment of peri-implantitis during 2006. The patients had clinical signs of peri-implantitis around one or more dental implants (i.e.>or=6 mm pockets, bleeding on pockets and/or pus and radiographic images of bone loss to>or=3 threads of the implants) and remaining teeth in the same and/or opposite jaw. The following clinical variables were recorded: Plaque Index (PI), Gingival Bleeding Index (GBI) Probing Pocket Depth (PPD), Access/capability to oral hygiene at implant site (yes/no), Function Time. The patients were categorized in the following sub-groups: Periodontitis/No periodontitis, Bone loss/No bone loss at teeth, Smoker/Non-smokers. RESULTS: Out of the 23 patients, the majority (13) had minimal bone loss at teeth and no current periodontitis; 5 had bone loss at teeth exceeding 1/3 of the length of the root but not current periodontitis and only 5 had current periodontitis. Six patients were smokers (i.e. smoking more than 10 cig/day). The site level analysis showed that only 17 (6%) of the 281 teeth present had >or=1 pocket of >or=6mm, compared to 58 (53%) of the total 109 implants (28 ITI and 81 Brånemark); 74% of the implants had no accessibility to proper oral hygiene. High proportion of implants with diagnosis of peri-implantitis were associated with no accessibility/capability for appropriate oral hygiene measures, while accessibility/capability was rarely associated with peri-implantitis. Indeed 48% of the implants presenting peri-implantitis were those with no accessibility/capability for proper oral hygiene (65% positive predict value) with respect to 4% of the implants with accessibility/capability (82% negative predict value). CONCLUSION: The results of the study indicate that local factors such as accessibility for oral hygiene at the implant sites seems to be related to the presence or absence of peri-implantitis. Peri-implantitis was a frequent finding in subjects having signs of minimal loss of supporting bone around the remaining natural dentition and no signs of presence of periodontitis (i.e. presence of periodontal pockets of >or=6 mm at natural teeth). Only 6 of the examinated subjects were smokers. In view of these results we should like to stress the importance of giving proper oral hygiene instructions to the patients who are rehabilitated with dental implant and of proper prosthetic constructions that allow accessibility for oral hygiene around implants.
Information about the oral status and dental health behavior and the working history of 369 Finnish seamen on different types of ships was gathered by means of a questionnaire. A control group of workers on shore was formed for sailors 35-44 years of age. Removable dentures were worn by 16% of the seamen. Oral disorders during the week before the study were reported by one-third. During the previous 2 years 14% of the sailors had had at least one episode of oral troubles, 15% twice and 9% three or even more times. One-third of seamen with oral trouble had needed pain-killing tablets or antibiotics. Sick leave days had been needed by 3% of respondents during the previous 2 years because of oral disorder (mean length of sick leave period was 1.4 days). The control group reported gum bleeding more often than the seafarers. Even though there were no signs of poorer dental condition in sailors than in the controls on shore, the possibility that the seafaring could constitute a risk for the oral health of seamen in other age groups cannot be excluded.
