Background: This paper assesses the oral health status in a prison population and identifies risk factors associated with oral health. Methods: Cross-sectional stratified random sample of 789 prisoners (657 males and 132 females) from 27 correctional centres across New South Wales, stratified by sex, age and aboriginality. A face to face interview was used to collect information on health status and behavioural risk factors. A subset of participants (312 males and 22 females) received an oral examination which enabled the decayed, missing or filled permanent teeth (DMFT) score to be calculated.

This paper presents some information, derived by questionnaire, on the social characteristics and background of 1148 first-year dental students at the University of Sydney for the years 1976-1985. Student entry age was 19.4 years; 27 per cent were female; 36 per cent of fathers and 24 per cent of mothers were professionals and 37 per cent of fathers and 11 per cent of mothers had attended university; parents of female students had higher educational levels than parents of male students; 55 per cent had medicine as the course of first preference. Eighty-five per cent of students entered dentistry from high school with 78 per cent from Sydney. Characteristics of students showed little change over the period 1976-1985. Some changes noted were an increase in the number of female students with fewer living in their parents' home; increase in number of students from government schools; decrease in foreign students but an increase in students (Australian citizens, or residents) born overseas, and of different ethnic backgrounds.

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.

Bite-wing radiographs were used to determine the effect of three forms of topical SnF2 therapy on the progression of initial lesions in the approximal surfaces of permanent posterior teeth. Radiographs were taken annually over a four-year period. The subjects were schoolchildren, aged 12-14 yr, living in a low fluoride area. The professional application of a 10% SnF2 solution for 30 s, semi-annually for two yr, had no discernible effect on the development of the initial lesions. However, the home use of a SnF2 dentifrice did inhibit caries progression appreciably at all but one of the four time intervals in the study. The professional application of a 10% SnF2 solution for 30 s, semi-annually for two yr, combined with the home use of a SnF2 dentifrice, was the most effective treatment in retarding lesion development. Even without topical fluoride therapy, the rate of progression of initial approximal lesions was generally quite slow. In view of these findings, it would seem sound clinical practice to treat all initial lesions in approximal surfaces with topical fluoride therapy and delay placement of restorations until there is radiographic evidence of lesions reaching dentin.

The periodontal status and treatment needs were determined for a consecutive sample of 200 subjects 15 years and over who presented at the Assessment and Diagnosis Department at the Westmead Hospital Dental Clinical School. A partial recording of the Community Periodontal Index of Treatment Needs using 10 index teeth for subjects 20 years and over and six index teeth for subjects under 20 years was used.Periodontal disease prevalence was high (with 98 per cent affected) but in most subjects it was of mild to moderate severity. Advanced periodontal disease (pockets of 6 mm or more) was present in 15 per cent of the sample.The major treatment requirement in all age groups was for simple periodontal care involving scaling and oral hygiene instruction that could be managed by non‐specialist dental resources.
