A cross-sectional study to assess the prevalence of early childhood caries and associated risk factors in preschool children in district Mandi, Himachal Pradesh

AIM

The aim of this cross-sectional study is to investigate the prevalence and related risk factors of early childhood caries (ECC) in preschool children of district Mandi, Himachal Pradesh, India.

MATERIALS AND METHODS

A total sample of 2859 children aged between 2 and 6 years were selected from various parts of district Mandi. The status of dental caries and decayed missing and filled teeth (DMFT) score was recorded.

RESULTS

ECC increased significantly with age. Boys had significantly higher caries prevalence and mean DMFT score as compared to girls. Children who belonged to low socioeconomic group showed higher caries prevalence and mean DMFT score. Children aged 3-6 years who brushed their teeth twice daily had the least prevalence of dental caries as well as DMFT score when compared to children with one time and no brushing.

CONCLUSION

The early identification of poor oral hygiene and improper feeding habits should be considered in preventive health promotion in low socioeconomic communities of district Mandi, Himachal Pradesh.

Reusing electronic patient data for dental clinical research: a review of current status

OBJECTIVES

The reuse of electronic patient data collected during clinical care has received increased attention as a way to increase our evidence base. The purpose of this paper was to review studies reusing electronic patient data for dental research.

DATA SOURCES

1527 citations obtained by searching MEDLINE and Embase databases, hand-searching seven dental and informatics journals, and snowball sampling.

STUDY SELECTION

We included studies reusing electronic patient data for research on dental and craniofacial topics, alone or in combination with medical conditions, medications and outcomes. Studies using administrative or research databases and systematic reviews were excluded. Three reviewers extracted data independently and performed analysis jointly

RESULTS

The 60 studies reviewed covered epidemiological (32 studies), outcomes (16), health services research (10) and other (2) topics; were primarily retrospective (58 studies); varied significantly in sample size (9-153,619 patients) and follow-up period (1-12 years); often drew on other data sources in addition to electronic ones (25); but rarely tapped electronic dental record (EDR) data in private practices (3). Type of research was not associated with data sources used, but research topics/questions were. The most commonly reported advantages of reusing electronic data were being able to study large samples and saving time, while data quality and the inability to capture study-specific data were identified as major limitations.

CONCLUSIONS

Dental research reusing electronic patient data is nascent but accelerating. Future EDR design should focus on enhancing data quality, begin to integrate research data collection and implement interoperability with electronic medical records to facilitate oral-systemic investigations.

CLINICAL SIGNIFICANCE

Measuring and improving the quality of dental care requires that we begin to reuse electronic patient data collected in practice for clinical research. Practice data can potentially serve as a useful complement to data collected in traditional research studies.
