Neuromuscular function in healthy occlusion

JOURNAL OF ORAL REHABILITATION, Issue 9 2010
S. E. FORRESTER
Summary, This study aimed to measure neuromuscular function for the masticatory muscles under a range of occlusal conditions in healthy, dentate adults. Forty-one subjects conducted maximum voluntary clenches under nine different occlusal loading conditions encompassing bilateral posterior teeth contacts with the mandible in different positions, anterior teeth contacts and unilateral posterior teeth contacts. Surface electromyography was recorded bilaterally from the anterior temporalis, superficial masseter, sternocleidomastoid, anterior digastric and trapezius muscles. Clench condition had a significant effect on muscle function (P = 0·0000) with the maximum function obtained for occlusions with bilateral posterior contacts and the mandible in a stable centric position. The remaining contact points and moving the mandible to a protruded position, whilst keeping posterior contacts, resulted in significantly lower muscle activities. Clench condition also had a significant effect on the per cent overlap, anterior,posterior and torque coefficients (P = 0·0000,0·0024), which describe the degree of symmetry in these muscle activities. Bilateral posterior contact conditions had significantly greater symmetry in muscle activities than anterior contact conditions. Activity in the sternocleidomastoid, anterior digastric and trapezius was consistently low for all clench conditions, i.e. <20% of the maximum voluntary contraction level. In conclusion, during maximum voluntary clenches in a healthy population, maximum masticatory muscle activity requires bilateral posterior contacts and the mandible to be in a stable centric position, whilst with anterior teeth contacts, both the muscle activity and the degree of symmetry in muscle activity are significantly reduced.

AUSTRALIAN AND NEW ZEALAND JOURNAL OF PUBLIC HEALTH, Issue 5 2008
Kaye F. Roberts-Thomson
Abstract Objectives:The aim of this study was to assess social inequality in use of dental services by examination of visiting for relief of pain and receipt of extractions. Methods: Data were collected in the period of 2004-06, from a stratified clustered sample of Australians aged 15+ years, using a computer-aided telephone interview. Analysis was restricted to n=10,099 dentate adults. Results: Visiting for relief of pain varied by age, country of birth, education and income with lower odds (Odds ratio, 95%CI) among 55-74 (0.43, 0.35-0.54) and 75+ year-olds (0.22, 0.15-0.33) compared to the 15-34 year-olds, lower odds among Australian-born persons (0.82,0.69-0.98) compared to those born overseas, higher odds for those with no post-secondary education (1.31, 1.07-1.61) and with TAFE, trade or other qualifications (1.34, 1.09-1.66) compared to university qualified, and for those in the <$20,000 income group (1.61, 1.23-2.12), the $20,000-<$40,000 (1.53, 1.20-1.96) and the $40,000-<$60,000 group (1.33, 1.02-1.72) compared to <$80,000+. Receipt of extractions varied by age, sex, qualifications and income, with lower odds of extraction among persons of 75+ years (0.61,0.40-0.93) compared to the youngest age group, higher odds among males (1.34, 1.13-1.59) compared to females, those with no post-secondary education (1.59, 1.27-1.99) and with TAFE, trade or other qualifications (1.49, 1.21-1.84) compared to university qualified, and for the income groups <$20,000 (3.06, 2.27-4.12), $20,000-<40,000 (2.37, 1.80-3.12) and $40,000-<60,000 (1.94 1.47-2.55) compared to the $80,000+ income group. Conclusions: The results indicate social inequality in provision of dental services and suggest an urgent need for the dental profession and governments to address this inequality. [source]


Job characteristics and the subjective oral health of Australian workers

Objectives: To examine the associations between hours worked, job security, skill maintenance and work and home interference and subjective oral health; and to compare findings for different occupational groups. Methods: Data were collected in 1999 from a random stratified sample of households in all Australian States and Territories using a telephone interview and a questionnaire survey. Subjective oral health was evaluated with the short form Oral Health Impact Profile (OHIP-14), which assesses the adverse impact of oral conditions on quality of life. Results: Data were obtained for 2,347 dentate adults in the workforce. In the 12 months preceding the survey, 51.9% had experienced oral pain and 31.0% reported psychological discomfort from dental problems. Males, young adults, Australian-born workers, and those in upper-white collar occupations reported lower mean OHIP-14 scores (ANOVA p<0.001). Having controlled for the effects sex, age, country of birth and socio-economic factors in a linear multiple regression analysis, hours worked, skill maintenance and work and home interference were significantly associated with OHIP-14 scores for all workers. While part-time work was associated with higher OHIP-14 among upper white-collar workers, working >40 hours a week was associated with higher OHIP-14 scores for other workers. Conclusions: Aspects of the work environment are associated with the subjective oral health of workers. Because these contexts are subject to only limited control by individual workers, their influence is a public health issue. [source]


Social Inequality: Social inequality in perceived oral health among adults in Australia

AUSTRALIAN AND NEW ZEALAND JOURNAL OF PUBLIC HEALTH, Issue 2 2004
Anne E. Sanders
Objective: To establish population estimates of self-assessed tooth loss and subjective oral health and describe the social distribution of these measures among dentate adults in Australia. Methods: Self-report data were obtained from a nationally representative sample of 3,678 adults aged 18,91 years who participated in the 1999 National Dental Telephone Interview Survey and completed a subsequent mail survey. Oral health was evaluated using (1) self-assessed tooth loss, (2) the 14-item Oral Health Impact Profile, and (3) a global six-point rating of oral health. Results: While the absolute difference in tooth loss across household income levels increased at each successive age group (18,44 years, 45,64 years, 65+ years) from 0.7 teeth to 6.1 teeth, the magnitude of the difference was approximately twofold at each age group. For subjective oral health measures, the magnitude of difference across income groups was most pronounced in the 18,44 years age group. In multivariate analysis, low household income, blue-collar occupation, and high residential area disadvantage were positively associated with social impact from oral conditions and pathological tooth loss. Speaking other than English at home (relative to English), low household income (relative to high income), and vocational relative to tertiary education were each associated with more than twice the odds of poor self-rated oral health. Conclusions: Significant social differentials in perceived oral health exist among dentate adults. Inequalities span the socio-economic hierarchy. Implications: In addition to improving overall levels of oral health in the adult community, goals and targets should aim to reduce social inequalities in the distribution of outcomes. [source]

Abstract Background:, The aim of this study was to evaluate relative change over 17 years in clinical oral health outcomes inside and outside capital city areas of Australia. Methods:, Using data from the National Oral Health Survey of Australia 1987,88 and the National Survey of Adult Oral Health 2004,06, relative trends in clinical oral health outcomes inside and outside capital city areas were measured by age and gender standardized changes in the percentage of edentate people and dentate adults with less than 21 teeth, in mean numbers of decayed, missing and filled teeth, and mean DMFT index. Results:, There were similar reductions inside and outside capital city areas in the percentage of edentate people (capital city 63.7%, outside capital city 60.7%) and dentate people with less than 21 teeth (52.5%, 50.1%), in the mean number of missing teeth (34.3%, 34.5%), filled teeth (0.0%, increase of 5.5%), and mean DMFT index (21.2%, 19.2%). The reduction in mean number of decayed teeth was greater in capital city areas (78.0%) than outside capital city areas (50.0%). Conclusions:, Trends in four of the five clinical oral health outcomes demonstrated improvements in oral health that were of a similar magnitude inside and outside capital city areas of Australia.

Abstract,,, Objectives:, To describe oral health-related quality of life (OHRQoL) among New Zealand adults and assess the relationship between clinical measures of oral health status and a well-established OHRQoL measure, controlling for sex, socioeconomic status (SES) and use of dental services. Methods:, A birth cohort of 924 dentate adults (participants in the Dunedin Multidisciplinary Health and Development Study) was systematically examined for dental caries, tooth loss, and periodontal attachment loss (CAL) at age 32 years. OHRQoL was measured using the 14-item Oral Health Impact Profile questionnaire (OHIP-14). The questionnaire also collected data on each study member's occupation, self-rated oral health and reasons for seeing a dental care provider. SES was determined from each individual's occupation at age 32 years. Results:, The mean total OHIP-14 score was 8.0 (SD 8.1); 23.4% of the cohort reported one or more OHIP problems ,fairly often' or ,very often'. When the prevalence of impacts ,fairly/very often' was modeled using logistic regression, having untreated caries, two or more sites with CAL of 4+ mm and 1 or more teeth missing by age 32 years remained significantly associated with OHRQoL, after adjusting for sex and ,episodic' dental care. Multivariate analysis using Poisson regression determined that being in the low SES group was also associated with the mean number of impacts (extent) and the rated severity of impacts. Conclusions:, OHIP-14 scores were significantly associated with clinical oral health status indicators, independently of sex and socioeconomic inequalities in oral health. The prevalence of impacts (23.4%) in the cohort was significantly greater than age- and sex-standardized estimates from Australia (18.2%) and the UK (15.9%). [source]
