An appraisal of the quality of published qualitative dental research.

OBJECTIVES To appraise the quality of published qualitative research in dentistry and identify aspects of quality, which require attention in future research. METHODS Qualitative research studies on dental topics were appraised using the critical appraisal skills programme (CASP) appraisal framework for qualitative research. The percentage of CASP criteria fully met during the assessment was used as an indication of the quality of each paper. Individual criteria were not weighted. RESULTS Forty-three qualitative studies were identified for appraisal of which 48% had a dental public health focus. Deficiencies in detail of reporting, research design, methodological rigour, presentation of findings, reflexivity, credibility of findings and relevance of study were identified. Problems with quality were apparent irrespective of journal impact factor, although papers from low impact factor journals exhibited the most deficiencies. Journals with the highest impact factors published the least qualitative research. CONCLUSIONS The quality of much of the qualitative research published on dental topics is mediocre. Qualitative methods are underutilized in oral health research. If quality guidelines such as the CASP framework are used in the context of a thorough understanding of qualitative research design and data analysis, they can promote good practice and the systematic assessment of qualitative research.

Research in primary dental care. Part 6: Data analysis

The analysis of data from a research project seeks to answer the research question which the investigators set at the outset of the study. This article provides information on data analysis for both quantitative and qualitative data, always referring the reader back to their initial research question. Advice is also given on software which can be used for the analysis of data. A guide is provided to the choice of appropriate statistics for studies involving quantitative data.

Research in primary dental care part 3: Designing your study.

Earlier articles in this series identified the importance of stating a clear research question as the first step in conducting research in primary dental care. The study design seeks to answer the research question. This article describes different types of study design and their application. A framework of the steps involved in designing each type of study are described, together with the situations in which they could be used. Useful resources and sources of information are provided.

Research in primary dental care - Part 4: Measures

An important part of the design process for any study is deciding how to assess and measure the phenomena you are aiming to research. In this article we will use the term outcome measure to indicate the tool or index that can be used to quantify, in an accurate and predicable way, the phenomenon under investigation. This might, for example, be a patients opinion, the effect of a treatment, the outcome of an intervention, or the prevalence of an oral disease. The paper presents an overview of outcome measures which can be used in research. We will discuss the properties to look for in a measure, suggest suitable evidence-based measures and briefly introduce how to go about developing new measures, in particular, questionnaires.

Inequalities in the provision of NHS primary care dental services in Scotland in 2004.

Objective To assess inequalities in the provision of National Health Service (NHS) primary care dental services between Health Boards and the four provider groups (General Dental Service [GDS] non-specialist, GDS salaried, specialist working in primary care, Community Dental Service [CDS]) in Scotland. Methods A postal questionnaire survey of all dentists (N=2852) registered with the General Dental Council at an address in Scotland was undertaken. The following were assessed: the proportion of primary care dentists not accepting new children/adults for NHS care or using a waiting list, the proportion of dentists working in wheelchair-accessible surgeries, furthest distance travelled by patients to primary care surgery in an average week, waiting time for routine NHS treatment, and the proportion of dentists offering weekend or evening appointments to NHS patients. Data were analysed by Health Board and the four provider groups. Results A total of 2134 (74.8%) completed questionnaires were returned. One thousand, five hundred and seventy-seven dentists (73.9%) of the respondents were providing NHS primary care dental services for at least part of each week. There was a wide variation in the provision of NHS primary care dental services between Health Boards. Borders, Dumfries and Galloway, and Grampian performed poorly on most indicators, whereas Lanarkshire, Greater Glasgow, and Argyll and Clyde generally performed well. The CDS scored well on most indicators of service provision. There were problems with the provision of specialist dental services in primary care, and GDS services provided by Health Boards. Conclusions Because the problem issues differed between Health Boards and the four provider groups, it is likely that both local and national solutions are required to improve the provision of services. Further research on service demand is required to confirm the apparent inequalities in provision suggested by the study.
