Clinical follow-up study of third molar eruption from ages 20 to 26 years.

The development of 412 upper and lower third molars was clinically followed up for 6 years in 120 students, starting at the age of 20 years. Clinical and radiographic examinations carried out at baseline and 6 years later showed that during the follow-up period almost half the third molars originally recorded as partially erupted had erupted. When the lower third molars were initially invisible, only 9% of them had erupted by age 26 years whereas 29% remained invisible. When third molars had been already erupted at baseline, only a few were extracted during the 6-year follow-up period. It was concluded that a certain proportion of third molars erupt relatively late, and therefore the need for surgical interventions may decrease with age during early adulthood.

Assessing the eruption of lower third molars on the basis of radiographic features.

To determine radiographic features by which one could estimate whether lower third molars are likely to erupt after the age of 20 years, university students with a total of 84 unerupted or partially erupted lower third molars were followed up. Five radiographic features of each third molar were measured from the panoramic tomogram taken at age 20 years, and the status of third molars was examined for a second time at age 26 years. The results showed that the lower third molars that did erupt after the age of 20 years were initially: 1) root formation complete; 2) impacted in soft tissue; 3) vertical; 4) placed at the same occlusal level as the neighbouring second molar; 5) showed sufficient space between the ramus and the second molar. In contrast, the teeth that remained impacted at the age of 26 years showed such initial features as: 1) incomplete root formation; 2) embedding in bone; 3) mesioangularity; 4) situated at the cervical level of the neighbouring second molar. It was concluded that a panoramic tomogram taken at age 20 years revealed radiographic features on which an estimation of future eruption of mandibular third molars could be based.

Effect of antiseptic mouthwashes on some clinical and microbiological findings in the mouths of lymphoma patients receiving cytostatic drugs.

51 patients suffering from Hodgkin's disease or non-Hodgkin's lymphoma participated in this double-blind, cross-over study in which 2 antiseptic mouthwashes were tested for their effects on various periodontal index scores and salivary microbial counts. All patients were receiving combination cytostatic treatment based on methotrexate and doxorubicin. The patients (49 +/- 14 years old, 28 men, 23 women) were allotted at random to 2 groups. One rinsed with a 0.12% chlorhexidine gluconate (CHX) solution, the other with a 0.025% amine-stannous fluoride (AmF + SnF) solution 2x daily for 2 weeks. Both groups then continued rinsing with a 0.05% sodium fluoride (F) solution for 2 weeks, before switching over to AmF + SnF or CHX, respectively. All solutions had been prepared in such a way that they had the same colour and taste. Visible plaque index and gingival bleeding index scores were significantly reduced after periods of rinsing with CHX solution (P less than 0.001) and AmF + SnF solution (P less than 0.05). Microbiological cultivations of saliva specimens revealed significant reductions in mutans streptococci immediately after commencing rinsing, while lactobacilli and yeast counts were not affected.

Finnish dentists as tobacco counselors.

The first nationwide survey of Finnish dentists' use of tobacco, their inquiring about and advising patients on tobacco use, and their attitudes toward anti-tobacco health education (ATHE) was carried out at the end of 1987. A questionnaire mailed to 540 dentists produced 435 answers (81%). One fourth of the male dentists and 6% of the female dentists currently were smokers, and 11% of men and 2% of women smoked daily. Information on smoking practices of patients was obtained always by 8%, often by 18%, and occasionally by 62% of the dentists. Four percent of the dentists advised always and 15% often their patients about smoking, and 62% did so occasionally. The majority of the dentists agreed that dentists should take part in ATHE and that dentists can encourage patients to stop using tobacco. The respondents supporting the involvement of dentists in ATHE reported having an active role in tobacco counseling (TC) significantly more frequently than those not sharing the idea of involvement. It was concluded that Finnish dentists could be a valuable resource in TC because of their positive attitudes.

Conceptions of dental amalgam and oral health aspects during pregnancy in Finnish women.

All 277 pregnant women (mean age 28.4 yr, SD 4.6) living at the Lohja municipal health center area in Southern Finland participated in a survey during the first 6 months in 1990. The women's own opinions of the effect of pregnancy on their oral health were questioned during their first trimester of gestation. A special emphasis was put on the attitudes of dental restorative materials. The results showed that 57% of the subjects would have accepted the use of any restorative material during pregnancy while 43% were against one or more materials. 77 (65%) were opposing dental amalgam. 129 women (47%) were of the opinion that pregnancy as such is detrimental to their dental health. This opinion was significantly more frequent among women who were pregnant for third or more times than those having their first gestation. 70 (26%) thought dental treatment to have an effect on their gestation. Also 70 subjects (26%) thought that dental treatment may affect normal development of the fetus. The results showed that in spite of the long tradition in maternity counseling in Finland, the conceptions among pregnant women are often erroneous from the dental point of view.

Oral health problems in Finnish conscripts.

The frequency of oral health problems in 353 Finnish conscripts aged 21.0 (SD 1.2 years) was studied by means of a questionnaire and by investigating the dental records. One hundred five (30%) conscripts had seeked dental help during their 8 months' military service. Forty-four percent of these patients had dental caries as their main diagnosis; endodontic problems comprised 9% of all cases. The problems related to third molars were second in frequency, accounting for 27% of the conscripts treated. Six and one-half percent of the patients had lost serving time on dental grounds (mean absence 3.6 days), most often (90%) due to acute pericoronitis or post-operative status following third molar surgery.

Number of remaining teeth and rehabilitation with removable dentures in psoriatics.

The aim of this investigation was to study associations between the state of dentition and socio-medical aspects in psoriatics. It was found that the number of remaining teeth in subjects under 65 years of age was higher in psoriatics with skin symptoms (P-group) than in psoriatics with skin and joint symptoms (PA-group) (P less than 0.01), this rate being higher than that found among the general population in Finland. In younger subjects, women in the P-group wore removable dentures more frequently than did women in the PA-group (P less than 0.05), whereas among older subjects men in the PA-group wore removable dentures more frequently than did men in the P-group (P less than 0.001). In the log-linear model that was applied, more advanced age, lower level of education and infrequent dental visits were associated with a low number of remaining teeth in both the P-group and the PA-group. A poor general state of health in the P-group and a high number of teeth, indicating that there is an association between severity of general disease and dental health status.

Oral health of workers in the modern Finnish confectionery industry.

The association between type of work and dental findings and the relevance of sugar dust as an occupational hazard to dental health was studied in workers producing sweets, biscuits, and bakery products, and in controls in a work environment not concerned with sugar. 298 employees, 42 +/- 11 yr of age, were investigated clinically and by means of chemical and microbiological tests of their saliva. Mean total time of work on the production line in question was 10 +/- 8.5 yr. Periodontal treatment needs increased similarly with increasing age in all subgroups. Subjects concerned with biscuit production had significantly higher DMFS values than subjects in the other groups. They also had significantly higher numbers of untreated cavities: 79.6% compared with 54.7% in those making sweets, 48.3% in bakery workers, and 62.6% in the controls not exposed to sugar. High levels of lactobacilli and Streptococcus mutans were found equally in all subgroups. Because work hygiene measurements have previously shown that sugar and flour dust concentrations were below accepted limits in the confectionery factory studied, the results do not seem to support the hypothesis that airborne sugar is an occupational dental health hazard. Some other factors need to be accounted for to explain the findings.

Burnout and its causes in Finnish dentists.

In the spring of 1986 burnout and its relation to social and physical environments and the nature of work were studied using a questionnaire sent to a sample of 232 dentists aged under 62 living in the province of Uusimaa, Finland. Most male and female dentists (71 and 67%, respectively) were working in group practices and most (88%) employed an assistant. Professional problems were generally (71%) solved by consulting colleagues. Half of those responding were very satisfied with their relationship to other dental staff. All but 9% of dentists experienced problems in their physical working environments and 22% felt that their uncomfortable working posture interfered significantly with job satisfaction. Women reported chronic work-related conditions diagnosed by a physician more often than men (21 vs. 10%, respectively). At the time of the study, most dentists were experiencing pain in connection with work on patients and 41% of women and 59% of men were experiencing occupational stress. Most dentists experienced at least temporary psychological fatigue as a result of their work and almost half were exhausted at the end of each day. Despite this, most enjoyed working with patients and were enthusiastic about their work. Three aspects of burnout emerged on factor analysis: psychological fatigue, loss of enjoyment of work, and hardening. One third of dentists experienced some hardening and ceased to care greatly what happened to some of their patients. Of the factors associated with working environments, only dissatisfaction with relationships with patients, problems relating to the physical environment and poor working posture significantly increased burnout.(ABSTRACT TRUNCATED AT 250 WORDS)

Patients complaining about amalgam-related symptoms suffer more often from illnesses and chronic craniofacial pain than their controls.

All patients who during the academic year 1987-88 had come or were referred for investigation to the Institute of Dentistry, University of Oulu, because of their anticipated amalgam-related symptoms were included in the study. The group comprised 20 patients, 7 men and 13 women, 41.6 +/- 11.1 yr old. For paired controls, 20 age and sex matched subjects were randomly selected among other patients at the Institute. The subjects' medical and dental history was taken, they were all examined clinically, and saliva analyses were done. The subjects were tested with standard patch test series of 25 common dental allergens. All patients were given the possibility to give a blood test for mercury concentration analysis, but only five were willing to do so. The results showed that the group of 20 patients suffered significantly more often from medical illnesses than the controls (P less than 0.05). Chronic craniofacial pain was diagnosed significantly more often among the patients than in the controls (P less than 0.01). The controls had more caries than the patients, but there was no difference in any other clinical, salivary chemical or microbiological findings between the groups. In the five patients who gave blood samples, both inorganic and organic mercury levels were below threshold values. No difference was observed between the patients and controls in the allergy test reactions.

Effect on plaque growth and salivary micro-organisms of amine fluoride-stannous fluoride and chlorhexidine-containing mouthrinses.

Amine fluoride-stannous fluoride mouthrinse was tested in a double-blind cross-over clinical trial on 16 healthy subjects. Chlorhexidine mouthrinse prepared in the same colour and taste was used as the control. After a preparatory phase of 2 weeks, during which the subjects' plaque and gingival indices were reduced to zero by professional cleaning, 1-week test periods without mechanical cleaning were started in random order. The fluoride test solution did not prevent plaque accumulation and growth of salivary S. mutans and lactobacilli as did chlorhexidine. Furthermore, the plaque wet weight was statistically highly significantly greater during test periods of fluoride rinsing than during the chlorhexidine phase. The cleansing effect, as subjectively estimated by questionnaire, was in favour of chlorhexidine, but discolorations of teeth were assessed as significantly worse during chlorhexidine periods. Neither of the test solutions showed any effect on salivary flow rate, pH, buffering capacity, or lysosomal enzyme activity.
