Caries prevalence and fluoride use in low SES children in Clermont-Ferrand (France).

OBJECTIVE: To evaluate the association between dental caries experience and preventive behaviours of children residing in a deprived area in Clermont-Ferrand (France). PARTICIPANTS AND METHODS: All 4-5 yr-olds attending nine schools in deprived areas of the city were invited to participate and 81% (n=282) consented and were examined. Dental caries was recorded at the dentine threshold. Parents completed a questionnaire concerning family demographics and the child's use of fluoride. Non-parametric tests and logistic regression assessed the relative importance of SES and fluoride variables on dental status (dt>1). RESULTS: Fifty four (19%) of the examined children were living in families with an immigrant background, 33% were fully covered by the national health insurance programme for deprived families. Caries experience was high; mean dft was 1.94 (3.31) and 30% of the children had >1 carious teeth. Thirty percent of the families reported using fluoridated salt. Tooth brushing once daily was reported for 39% and twice daily for 26%. Parents declared supervising tooth brushing for 60%. Two thirds of the children, according to their parents, used fluoride supplement between birth and two years. Supervised tooth brushing was significantly correlated with lower mean dt scores. Systemic fluoride use was poorly related to dental caries Immigrant background, family size, type of health insurance and mother's unemployment were significantly correlated with caries prevalence. In multivariate analysis, immigrant status, supervised tooth brushing and parental knowledge about fluoride in toothpastes were significant caries predictors. CONCLUSIONS: The majority of low SES children did not practice effective caries prevention; few reported twice daily brushing with fluoride toothpaste. Caries experience was very high and much was untreated. Immigrant status, supervised tooth brushing and parental knowledge about fluoride in toothpastes were significant caries predictors.

Tooth follicle extirpation and uvulectomy.

Migration is not only the movement of people, but also of their culture, customs and beliefs. As more people from developing countries in Africa migrate to industrialized countries, the more likely health professionals will find themselves providing care for people of whose customs and practices they have little knowledge. This review of the literature suggests that removal of deciduous canine follicles and uvulectomy are frequently practised in some African and neighbouring countries. Reasons given for deciduous canine extirpation include the prevention of vomiting, fever and diarrhoea. The indications for uvulectomy appear widespread, including treatment for persistent fever, coughing and growth retardation. The practices are usually performed by traditional healers. Risks for children who undergo these procedures are extensive, including septicaemia, potential for HIV transmission, numerous dental complications and death. With improved understanding between Western health teams and local, traditional people, an improved system may develop whereby the two systems can work together in providing improved health outcomes for the people.

Dental caries and fluoride exposure in Western Australia.

Most water supplies in Western Australia (WA) have been fluoridated since about 1968, but one region has persistently resisted. Supplement use has been encouraged there, and fluoride toothpaste is widely used. Caries prevalence and caries experience in children in Perth (F- 0.8 mg/L) have declined steadily since fluoridation, but in the Bunbury region (F- less than 0.2 mg/L), caries measures remain higher than in Perth. The purpose of this study was to correlate the magnitude and timing of fluoride exposure with caries experience. Altogether, 592 randomly selected children born in 1978 (mean age, 11.8 years) in Perth and the Bunbury region provided residence and fluoride exposure information for the periods from birth to four and from four to 12 years of age. Caries experience was recorded clinically in accordance with DMFT and WHO criteria. Sixty-one percent had been continuous residents of fluoridated areas from birth to four years, and 51% between the ages of four and 12 years. Fluoride supplement use was low. By the age of 1.5 years, 42% had used toothpaste. The prevalence of caries was 0.38 in Perth and 0.61 in the Bunbury region, and mean DMFT scores were 0.89 (SD, 1.39) and 1.57 (SD, 1.60), respectively. Bivariate analysis revealed all fluoride exposure to be associated with reduced caries experience, but there were large correlations between some variables. When unconditional logistic regression analysis was used, the most important (p less than 0.05) odds ratios associated with no caries experience were for residence in a fluoridated area from four to 12 years of age and early use of toothpaste.(ABSTRACT TRUNCATED AT 250 WORDS)

Perceptions of dental fluorosis.

Mild dental fluorosis has long been accepted as a side-effect of water fluoridation and, more recently, has been recognized as a consequence of the use of other fluoride-based caries-preventive strategies. Traditionally, dental health professionals have not seen this as being of public health importance, but members of the public have not been asked their opinion. The purpose of the present study was to gather the opinions of lay groups concerning the appearance of the teeth of children with various degrees of fluorosis. Twenty-eight children, born in 1978, who had earlier participated in a study of fluorosis in Perth (Western Australia), allowed 110 observers to look at their upper central incisors under good viewing conditions. Fluorosis in these teeth ranged from TF score 0 (no fluorosis) to TF score 3. The observers were university students, parents, public servants, or dentists. They responded to statement items about the appearance of the teeth. The results, based on just over 3000 responses, showed that lay and dental observers could distinguish between different fluorosis levels. In response to a statement that the teeth appeared pleasing, a large majority agreed when the TF score was 0, but agreement declined as the TF score increased; when the TF score was 3, most people disagreed. Similarly, observers felt that the appearance would increasingly embarrass the child as the TF score increased. Observers, except the dentists, tended to feel that higher TF scores indicated neglect on the part of the child.(ABSTRACT TRUNCATED AT 250 WORDS)

Dental fluorosis and fluoride exposure in Western Australia.

Dental fluorosis in children is reported from many locations, and its prevalence may be increasing. This study aimed to measure fluorosis in 12-year-olds in fluoridated and non-fluoridated areas of Western Australia and to relate this to exposure. School dental clinics in Perth (F- 0.8 mg/L) and the Bunbury area (F- less than 0.2 mg/L) were the sampling units. Parents provided data on residence in fluoridated areas and on use of supplements and toothpaste. Exposure to water and supplemental fluoride between birth and four years was calculated. Clinical examinations (upper left central incisor) based on the TF classifications of fluorosis (which requires teeth to be dried) were conducted for 338 children in Perth and 321 in the Bunbury region. Re-examinations (n = 50) gave a weighted kappa of 0.78. Contingency analysis estimated bivariate relationships, and multiple logistic regression estimated odds ratios (OR) for risk factors. Fluorosis prevalence in the Perth region was 0.40, and in the Bunbury region 0.33 (chi 2 = 3.69, df = 1, p = 0.055). Prevalence was 0.44 in children with fluoride exposure equivalent to optimal water fluoridation and 0.20 among those with the lowest exposure (chi 2 = 35.99, df = 1, p = 0.0001). Increasing exposure was associated with higher fluorosis prevalence and higher TF scores, but overall, 27.3% of participants had TF score 1 (barely discernible), and only 9.4% had TF score greater than or equal to 2.(ABSTRACT TRUNCATED AT 250 WORDS)

Can organised dental care for children be both good and cheap?

Children's dental services evolved from emergency, pain-relieving and later amalgam-based care systems of the early and middle 20th century. The pattern of occurrence of dental caries is different today and young teenagers have very few teeth affected by caries. Restoration of lesions in permanent teeth, typically on occlusal or buccal/lingual surfaces, is technically simple. Paradoxically, dental students today are expected to master a vast amount of knowledge, including information on new dental materials and techniques. New dentists who choose to provide dental care for children as a career will spend most of their days placing fissure sealants, applying topical fluorides and inserting predominantly single-surface restorations. Because of their expensive training, new dentists will nevertheless expect high earnings, and this results in a high cost for children's dental care. The opportunity cost is other health services foregone. In developing countries where there are few dentists, they are almost not available for children at all. Costs could be reduced by reducing the number of interventions, and by reducing staff costs. Fewer interventions could be achieved by longer recall intervals: several studies and experience from places where this has been implemented indicate that is safe and effective. Widespread delegation of operative work to appropriately trained dental hygienists or therapists would reduce staff costs. Dental therapists are better substitutes for dentists in children's care because they are trained to do most of the clinical procedures that are necessary in children's dentistry. In Western Australia and South Australia, most dental care for children is provided by dental therapists. The costs of care are much lower and the outcome, as measured by caries experience and numbers of treated patients, is equivalent to or even better than European dentist-based services. Already, in some places, politicians and others are querying the need for organised children's dental care. Increased effectiveness will make continuation of children's dental services easier to sustain.

Fluoride supplements for young children: an analysis of the literature focusing on benefits and risks.

The use of fluoride supplements to prevent caries has been advised for more than 100 years, but serious promotion of this strategy occurred only after the effectiveness of water fluoridation was established, in the late 1950s and 1960s. Although the effectiveness of fluoride supplements was apparently endorsed by many small clinical studies, closer examination of the experimental conditions of these, their methods and the analysis of their results undermined confidence in their findings. It is likely that confounding resulted in spurious conclusions in many of them. More modern, well-conducted clinical trials of supplements suggest that today, in children also exposed to fluoride from other sources such as toothpaste, the marginal effect of fluoride supplements is very small. There is evidence that fluoride lozenges, designed to maximise any local effect, may have a small caries preventive effect, particularly in deciduous teeth. Overall, poor compliance makes fluoride supplements a poor public health measure. Supplement use by young children is associated with a substantial risk of dental fluorosis. Fluorosis is an issue about which the public is becoming concerned in several countries and this concern, if translated into opposition to all fluoride use, could jeopardise the most successful caries preventive aid we have. The potential for dental fluorosis, concern about the public's reaction to this, the poor effectiveness of supplements and the public's poor compliance with their use are persuasive arguments for a radical reduction in the use of supplements by young children. Recent changes in fluoride dosage schedules and deferment of the age of commencing the use of supplements, implemented in many countries, have followed from these concerns. Supplements formulated as lozenges maximise topical exposure of enamel to fluoride and such products may offer older children and some adults a way of maintaining an elevated fluoride level in saliva at times when toothbrushing is not practical.

Community dentistry in Nordic dental schools.

Approximately a decade after the first plans for the teaching of community dentistry were made in the Nordic countries, a questionnaire survey of Nordic dental schools was conducted to find out to what extent community dentistry subjects had been introduced in undergraduate curricula. Replies were received from the 12 dental schools in Denmark, Finland, Norway and Sweden. These schools admitted 915 students in 1982-83. Seven had a department of community dentistry, and at least two others had plans to start one. About 100 h of teaching were given on community dentistry subjects during the 5-yr course of study, mostly on the traditional subjects of epidemiology, statistics, law and ethics. In some schools health education and other behavioral sciences subjects received a large amount of curriculum time. Decisionmaking theory and political science were not reported taught at any school. Three departments had attached clinics, with widely differing functions. The Nordic textbook in community dentistry was widely used, and separate examinations were held in community dentistry at most schools. Full-time postgraduate courses were offered at three schools. Although schools in all four countries expected the number of dental students to decrease in coming years, several schools expected community dentistry to expand with regard to curriculum time and staff, in keeping with trends in other countries.

Outcome measures in split mouth caries trials and their statistical evaluation.

The split mouth study design in trials of fissure sealants and restorative materials neatly controls for confounding by many of the variables associated with poor retention of sealants and occurrence of dental caries. Traditionally, the outcome measures used in split mouth trials have been material retention, (per cent) effectiveness and net gain. A survey of the literature revealed that a large proportion of split mouth studies report no statistical evaluation of outcome measures. In those studies in which statistical evaluation had been conducted, McNemar's X2 was the test most frequently used. This statistic is appropriate for comparing differences between "success" and "failure" tooth pairs (or "positives" and "negatives" in split mouth terminology) but it cannot evaluate directly effectiveness and net gain. The distributions of effectiveness and net gain are different and it would be desirable to estimate confidence intervals for them. In this paper, we consider these statistics, suggest methods by which confidence intervals may be calculated, and provide examples of the calculations. We demonstrate the close relationship between effectiveness (as used in split mouth trials) and relative effect and relative risk (as used in general epidemiological analysis) and recommend that relative risk should be the preferred outcome measure for split mouth trials. Whatever outcome measure is chosen in split mouth trials should always be subjected to statistical evaluation, preferably by the calculation of confidence intervals.

Recall intervals, dental hygienists and quality in child dental care.

Decline in dental disease and the need to provide dental care efficiently suggest changes in clinical and administrative routines in public dental care provision for children. A field project in Norway demonstrated productivity gains after the introduction of individualized recall intervals and using dental hygienists to conduct recall examinations. The purpose of the present study was to assess changes in the quality of dental health outcome and changes in the quality of the process of dental care provision. Recall intervals were increased from a target of 12 months to 16 and 18 months in two districts. Dental hygienists undertook all recall examinations and referred to dentists those patients who required operative care. Bitewing radiographs were inspected for all 18-yr-olds who were examined in 1989, 1990 and 1991 (n = 956) and for those who were examined before the changes were implemented in 1987 (n = 300). For each child, approximal caries on 24 surfaces was scored according to a 4-point severity scale. Clinical records were examined to determine what treatment had been provided. For each year after the changes were implemented, the quality of health outcome was assessed by comparing the radiographic caries prevalence and the number of sound surfaces with 1987 data. Quality in the process of care provision was indicated by the treatment decisions for approximal caries and by the proportion of uninterpretable surfaces on radiographs for each study year. The mean number of sound surfaces increased over time. A declining proportion of sound surfaces was restored over the study period, and almost all caries lesions extending deep into dentine were restored. Radiographic quality improved during the project period.(ABSTRACT TRUNCATED AT 250 WORDS)

Fluoride supplements and caries in a non-fluoridated child population.

In Norway, there is no water fluoridation and little naturally occurring fluoride in drinking water. Fluoride toothpaste is used by 95% of the population and there is a long tradition of use of fluoride supplements. The purpose of this study was to analyse whether children who used fluoride toothpaste regularly and complied with the recommendations for use of fluoride supplements had less caries than other children at the age of 8 years. Most fluoride supplements sold in Norway are lozenge-type tablets, which allow for extended enamel exposure to fluoride. All children (n = 551) born in 1988 living in a suburban community in Norway were invited to participate. In those who participated (n = 470), caries was registered clinically and radiographically and parents provided data on use of supplements. Thirty-eight percent of the children had used fluoride supplements regularly during the period 0.5 to 4.0 years of age and 66% used supplements regularly at the age of 6 to 8 years. Multivariate analyses showed that the children complying with the recommendations for use of fluoride supplements during the period 0.5 to 4.0 years of age had lower caries experience (dmfs) and fewer decayed surfaces (ds) in primary teeth than other children. No significant associations were found between supplement use in childhood and caries prevalence (DMFS) or number of decayed surfaces (DS) in permanent teeth at the age of 8 years. Supplement use from 6 to 8 years of age was not associated with caries occurrence either in primary or in permanent teeth. Both mother's education and the quality of dental hygiene were inversely associated with caries occurrence.

Periodontal disease and approximal overhangs on amalgam restorations in Norwegian 21-year-olds.

The prevalence of periodontal disease and overhanging approximal amalgam restorations in molars and premolars was registered in a clinical and radiographic examination of Norwegian adults (born 1959). A random sample of 250 persons was drawn from the populations of two neighboring towns where the Public Dental Services had operated different preventive programs. Results pertain to approximately 175 subjects whose mean age was 21.5 yr (SD 0.3). Twelve subjects had no gingival bleeding and the mean Gingival Bleeding Index of the group was 30.8 (SD 17.6). No pocket depth exceeded 5 mm. In eight subjects the radiographic distance from the cementoenamel junction to the interproximal alveolar crest was greater than 2 mm at one or more teeth. The mean number of filled approximal surfaces in molars and premolars was 12.8 (SD 6.8). Approximal overhangs were present in 87% of subjects, and at 1/4 of restorations. Ninety-six percent of overhangs were less than 0.5 mm. There was no significant difference between the different subgroups of the sample for any of the variables studied.

Effect of fluoride in amalgam on secondary caries incidence.

Caries incidence is falling in many developed countries but is believed to be increasing in developing countries. Insofar as treatment for caries is provided, ordinary amalgam restorations are usually the standard choice. These carry a risk of failing due to secondary caries. The aim of this study was to compare the occurrence of secondary caries adjacent to fluoride-containing amalgam with that adjacent to a conventional amalgam under field conditions in Bahrain. Children (n = 415) aged 6-14 yr who required occlusal restorations in two homologous contralateral permanent molar teeth were identified. Using the split-mouth design, one tooth received a fluoride-containing amalgam filling and the other a conventional amalgam restoration. A random method was used to determine which type of filling was placed on each side. After 4 yr, 357 children were still available for examination; of these 5 had to be eliminated from analysis for various reasons. Of the 704 teeth in the analysis, secondary caries had occurred in 135 (86 conventional amalgam, 49 fluoridated amalgam). By comparison with the conventional amalgam, the effectiveness of the fluoride amalgam was 43% (95% C.I. 24.4%, 57.1%) and the net gain 10.3% (95% C.I. 4.75%, 16.3%). The relative risk was 0.570 (95% C.I. 0.444%, 0.731%). Since fluoride amalgam has identical handling properties to conventional amalgam, performs similarly under clinical conditions and costs about the same, it should be the amalgam of choice for restorations in communities where the incidence of secondary caries is high.

Comparison of caries prevalence 7 years after discontinuation of school-based fluoride rinsing or toothbrushing in Norway.

The purpose of this study was to compare caries prevalence in two groups of 21-yr-olds 6-7 yr after discontinuation of school-based preventive programs consisting respectively of fortnightly rinsing or brushing 3-5 times per year with NaF solutions. Stratified random samples of 125 persons were drawn from appropriate population registers. Non-response was 30%. Blind clinical and radiographic examinations were carried out and the subjects were interviewed concerning their dental health related behavior. The results revealed significantly lower mean DMFS score in the rinsing than in the brushing group (P less than 0.001). Comparisons with results of other studies suggest persistence of benefits of school-based preventive programs after discontinuation.

Radiographic interpretation and treatment decisions among dental therapists and dentists in Western Australia.

All dentists and dental therapists employed in the Community Dental Services in Western Australia were invited to participate in a questionnaire study to find out about their use of radiographs and opinions and knowledge about the diagnosis of approximal caries. Replies were received from 45 dentists (95.1%) and 207 dental therapists (84.0%). Most dentists would not restore a lesion before it appeared on radiograph to have reached the dentine, while therapists were more likely to consider a restoration for a lesion just in enamel. Sixty percent of all respondents thought that a cavity was present when the radiographic lesion was confined to enamel. Fifty-seven percent of dentists thought that an average lesion took at least 12 months to progress from outer enamel to dentine, while a majority of dental therapists thought this would take less than 12 months. Radiographs were not frequently taken by the participants. Operators' opinions about cavity formation were the most important predictor of choice of treatment. In general, these participant's responses were similar to those provided by Norwegian and Dutch respondents in similar surveys conducted 5-6 yr ago, but the present participants worked in an optimally fluoridated area and might therefore have been expected to have adopted more cautious criteria for restorative treatment. Differences between dentists and dental therapists were generally not great. The results suggest that calibration of the operators in the service would offer benefits.

Radiographic caries diagnosis by clinicians in Norway and Western Australia.

In connection with continuing education courses in Norway and Western Australia (WA), dealing with caries diagnosis and treatment decisions, pre-tests were conducted. The pre-tests involved 433 dentists in Norway (ND), and 62 dentists (WAD) and 108 dental therapists (WAT) in WA, altogether 603 clinicians. Radiographs of 68 approximal surfaces were to be diagnosed and a treatment proposal was requested for each surface. ND showed the best overall diagnostic quality measured by the area beneath ROC-curve (P < 0.00001). The frequency of false-positive diagnoses (over-registrations) on sound surfaces varied between 7.1% (ND) and 11.9% (WAT) while the frequency of true-positive scores for lesions in the outer half of dentine varied from 57.4% (ND) to 48.1% (WAT). The mean numbers of restorations suggested by the three groups of clinicians were: ND: 14.3; WAD: 13.0; and WAT: 14.5. None of the differences was statistically significant. The proportion of sound surfaces proposed filled varied considerably between the groups, from 4.3% among Norwegian dentists to 10.6% among WAT (P < 0.0001). Of the lesions penetrating the outer half of dentine, the ND group would have restored 34.5% and the Australian clinicians somewhat fewer: WAD 25.6% and WAT 26.5%. The 11.3% of the ND who proposed more than two fillings on sound surfaces were responsible for 51.2% of the total number of filling proposals on sound surfaces. The corresponding numbers in the Australian group were 19.4% (WAD) and 33.3% (WAT) who made 73.6% and 75.7% of the restorative proposals on sound surfaces respectively.(ABSTRACT TRUNCATED AT 250 WORDS)

Variation in radiographic interpretation and restorative treatment decisions on approximal caries among dentists in Norway.

Of a random sample of dentists in Norway (n = 741), 83% responded to a questionnaire about their use of radiographs in and their opinions and knowledge about the diagnosis of approximal caries. There was great disparity in criteria for initiation of restorative treatment of approximal caries based on radiographic appearance. Two thirds of the dentists would do restorative treatment of lesions confined to enamel, the others would wait until lesions had reached the dentin before treatment was commenced. The criteria for restoration based on radiographic appearance was best correlated with the dentists' opinions about cavity formation. About 20% of the variation in criteria among dentists was explained by the radiographic appearance dentists associated wih the presence of a cavity. The majority of the dentists believed that approximal caries progressed faster than is indicated by progression studies. The interval between recall examinations using radiographs was not consistently shorter for dentists who decided to carry out operative caries treatment at a relatively advanced stage.

Dental status of 12-year-olds treated in private practice and a school dental service.

Different ways of service provision frequently lead to different services being provided. In the School Dental Service (SDS) in Western Australia, all 5-15-yr-olds are eligible for care free of charge and most avail themselves of the service. The parents of some children choose to use private dentists (typically copaying about 50% of the cost) and their children do not attend the SDS. This study aimed to compare the dental status of 12-yr-olds who attended private dentists with that of matched children enrolled in the SDS. Non-enrolled 12-yr-olds in Perth (F- 0.8 mg/l) were identified and asked to provide background information and participate in clinical examinations. Each non-enrolled participant was matched with a classmate of the same sex. Of 184 non-enrolled children, 100 actually participated. Data on caries experience (DMFT and DMFS), fissure sealants and gingival health (CPITN) were collected by clinical examination. Analyses used Wilcoxon's signed rank, categorical and t-tests and simple linear regression. Caries prevalence was lower in non-enrolled children (0.31) than in enrolled (0.47). Caries experience was also lower in non-enrolled children (mean DMFT 0.71 vs. 0.95, ns). Enrolled children had more FT than non-enrolled (Wilcoxon, P = 0.059) but the mean number of DT in each group was 0.14. Enrolled children had somewhat fewer fissure sealants than non-enrolled children but in enrolled children there was an apparent (P = 0.056) inverse relationship between number of fissure sealants and DMFT scores; this was not the case in the non-enrolled group, suggesting better targeting of fissure sealants in the SDS.(ABSTRACT TRUNCATED AT 250 WORDS)

Dental health of young Vietnamese immigrants.

About 3000 refugees from Vietnam have come to Norway in the last 5 years. A survey, including a clinical and radiographic examination for caries and gingival health, was carried out on 142 refugees. They were aged from 2 to 18 years and were examined within 6 weeks of arrival in Norway. The mean dmfs score of subjects 2-5 years old was 23.9, for subjects 6-11, dmfs was 12.4 and DMFS 7.7, and for subjects 12-18, DMFS was 20.0. The dmf/DMF scores were mainly composed of caries grades 3 and 4 (dentin caries or caries with pulpal involvement), and teeth missing or indicated for extraction. Only eight subjects had restorations, and these were often of poor quality. All subjects over 6 years had gingivitis (GBI 62%). About 10% had enamel hypoplasias on permanent anterior teeth. Dental abscesses and periapical areas indicated an acute treatment need, and most subjects were in urgent need of restorative treatment. Average time required for treatment of 12-18-year-old patients is estimated to be 7-10 hours, about four times that required for Norwegian schoolchildren. Dental examination of newly arrived Vietnamese refugees is recommended.

Validation of an oral health quality of life index (GOHAI) in France.

UNLABELLED: Oral health has traditionally been defined in terms of disease. Today, health is seen in a wider context: taking into account its impact on everyday living. Several indices attempt to capture this dimension. The Geriatric Oral Health Assessment Index (GOHAI) has been adapted for general use and tested on adult samples, mainly in North America. Language, cultural norms and the health care system in France are different and this raises the need to validate the GOHAI in France before it receives widespread use. OBJECTIVES: The purpose of this study was to test the validity of a French version of the GOHAI. METHODS: The GOHAI is based on responses to a 12-item self-administered questionnaire. The items were translated into French, back-translated and compared with the original. After pilot testing and minor modifications, the French version was administered to a group of low-income persons benefiting from the national health insurance system (n = 260, 18-45 years). Measures for stability and internal consistency were calculated. Concurrent and discriminant validity were assessed. RESULTS: Cronbach's alpha (0.86) showed a high internal consistency and homogeneity between items. Item-scale correlations varied between 0.40 and 0.78. Repeat administration of the GOHAI to 32 participants gave weighted kappa coefficients from 0.51 to 0.87 and a Pearson's correlation coefficient of 0.87. Low GOHAI scores were associated with perceptions of poor oral and general health, low satisfaction with oral health and a perceived need for dental care. There were significant relationships between the GOHAI score and most objective measures of dental status except FT. Younger, well-educated and higher income respondents were more likely to have a high GOHAI score. CONCLUSION: The French version of the GOHAI exhibits satisfactory psychometric properties but two items (one about swallowing, the other with complex sentence structure) had poor stability.
