- Chlorhexidine (CHX) has been incorporated in polymer-based varnishes to reduce mutans streptococci (ms) by the sustained release of CHX. Such varnishes often adhere well to teeth initially but are easily peeled off. To be effective, repeated application is necessary. Glass ionomer (GI) cements interacts with tooth minerals to form a stronger bond, and the inherent brittleness of the cement makes it difficult to remove in large fragments. The fluoride content may also reduce demineralisation. The aim of this study was to observe whether ms could be reduced interproximally and in saliva by a single application of a GI cement containing 3.3% CHX gluconate (CHX-GI). After professional tooth cleaning and a mouth rinse for 2 min with 0.2% CHX, the teeth of six subjects were coated with CHX-GI cement. An additional six subjects were treated with a GI cement that did not contain CHX, and seven subjects received professional tooth cleaning only. Ms samples were taken interproximally with the tooth pick method before and after treatment. Interproximal levels were classified according to the number of colony-forming units (c.f.u.) found: 0, 1-20, 21-100, and > 100. Saliva ms were sampled with the Strip Mutans method. After four weeks, the interproximal levels of ms had decreased only in the CHX-GI group (p < 0.05). In this group 9 of 14 highly colonised sites (> 100 c.f.u.) remained reduced throughout this period. In the GI and the untreated group a slight increase of ms interproximally was seen after one week. The interproximal ms scores in all groups approached baseline levels after 8 weeks. There were no significant differences in saliva ms levels between the groups during the test period. GI cement may be a possible vehicle for CHX in reducing ms interproximally.

- The aim of this epidemiological study was to analyse various clinical and radiographic data on oral health and compare the results to those of two cross-sectional studies carried out in 1973 and 1983. In 1973, 1983, and 1993 a random sample of 1000, 1104, and 1078 individuals, respectively were studied. The individuals were evenly distributed in the age groups 3, 5, 10, 15, 20, 30, 40, 50, 60, and 70 years. In 1983 and 1993 80-year-olds were also included. All subjects were inhabitants of the community of Jönköping, Sweden. The clinical and radiographic examination assessed edentulousness, removable dentures, implants, number of teeth, caries, restorations and overhangs, oral hygiene, calculus, periodontal status, endodontic treatment, and periapical status. The number of edentulous individuals was reduced by half from 1973 to 1993 and is now 8% in the age groups 40-70 years. The mean number of teeth has increased and up to the age of 50 years the individuals had more or less complete dentitions. During the 20-year period there was generally decreasing number of carious lesions and restorations. In the 15- and 20-year-olds, however, there was an increasing number of decayed/filled tooth surfaces in 1993 compared to 1983. Furthermore, after the age of 50 there was an increase in number of restored tooth surfaces. As regards secondary caries there was an increase for the 10- and 15-year-olds between 1983 and 1993. For all other age groups there were only minor differences. Generally restorations exhibited a high quality and 85-90% had no proximal overhangs. In 1973 this figure was about 60%. Concerning the frequency of tooth surfaces exhibiting plaque and gingival inflammation there was a considerable decrease from 1973 to 1983, but during the period from 1983 to 1993 there seems to be no improvement. In some age groups there was even a significant increase in plaque (15-year-olds) and gingivitis (3-, 5-, 15-, 20-, and 60-year-olds). The frequency of individuals with one or more periodontal pockets (> 4 mm) increased with age. In 1993 the bone level at the age of 40 years corresponded to the bone level at the age of 20 years in 1973. The percentage of endodontically treated teeth was lower in 1993 in all age groups than in 1973 and 1983. The percentage of endodontically treated teeth with periapical or juxtaradicular destructions was unchanged in all three studies. The comparison of the three studies from 1973, 1983, and 1993 shows that there has been a great improvement in oral health over this 20-year period. In 1993, however, the increasing number of decayed/filled tooth surfaces in the 15- and 20-year-olds and an increase in plaque and gingivitis in some younger age groups calls for special attention.

- The aim of the present study was to compare data on dental care habits and knowledge of oral health in three cross-sectional studies carried out in 1973, 1983, and 1993. The 1973 study constituted a random sample of 1000 individuals evenly distributed in the age groups 3, 5, 10, 15, 20, 30, 40, 50, 60, and 70 years. The same age groups with addition of a group of 80-year-olds were included in the 1983 and 1993 studies which comprised 1104 and 1078 individuals, respectively. A questionnaire (23-101 questions) about dental care habits and knowledge of oral health was used in connection with a clinical and radiographic examination. The same questions were used in all the three studies. An addition to the 1993 investigation was questions concerning ethnographic background. In 1993 approximately 95% of all individuals were visiting the dentist on a regular basis every or every second year. The 30-year-olds, however, did not visit a dentist as regularly in 1993 as in 1983. The 70- and 80-year-olds visited a dentist more regularly in 1993 than in 1983. An increased number of adults in all age groups, except for the 70-year-olds, received their dental care in the Public Dental Service in 1993 compared to 1983 and 1973. Most 40-year-olds and older, however, received their dental care by private practitioners. About 80% of all adults in 1993 were enrolled in a recall system on the dentist's initiative while in 1973 most appointments were based on the patient's own initiative. The number of individuals who felt discomfort at the prospect of an appointment with the dentist was more or less the same in 1973, 1983, and 1993. The knowledge of the etiology of dental diseases has not changed much between 1973 and 1993. The frequency of toothbrushing has increased since 1973 and in 1993 more than 95% of all individuals brushed their teeth daily. The use of dental floss and toothpicks as well as disclosing tablets decreased in 1993 compared to 1983. Almost all individuals in 1993 used fluoride toothpaste. The use of topical fluorides and fluoride tablets in children had decreased considerably in 1993 compared to 1983.

- 107 individuals, randomly selected from the County of Göteborg and Bohuslän, all born in 1970 were followed regarding the dental care received 1987-1989. The records of each individual from the actual time were collected and information on diagnosis and treatment measures was gathered. Radiographs from the actual time were studied by one of the authors. Sixty-two per cent of the adolescents had been examined and treated all 3 years. Six percent had not been seen at all. The sample was divided into three groups depending on the patient's DFSa value at the examination the first year. This classification appeared to correlate well with caries development in the following years. One-fourth of the sample was responsible for the major part of the non-attendance and late cancellations. The dental health of these subjects was below average, and non-attendance seemed to be a further risk factor. The preventive measures undertaken during the study appeared to correlate poorly with the actual situation of the patient and the presence or absence of potential risk factors.

Adverse health reactions in skin, eyes, and respiratory tract among dental personnel in Sweden

- Dental personnel manually handle products that contain monomers. Several studies have documented adverse health effects after exposure to such products. Gloves made of vinyl or latex are easily penetrated by monomers. Ordinary glasses, or visors, do not protect against vapour from polymer products. Dental face masks filter out about 40% of respirable particles. To survey the prevalence of asthma, atopic dermatitis, conjunctivitis, hay fever/rhinitis, and hand eczema among dental personnel, a questionnaire was distributed to all dental teams in Northern Sweden. Referents were researchers, teachers, and secretaries from the same geographical area. The response rate was 76% for dental teams, and 66% for referents. The results show a significantly higher prevalence of conjunctivitis, and atopic dermatitis among dentists, both male and female. Hypersensitivity to dental materials was reported by significantly more dental personnel than by referents.
