N2 - Objectives. To investigate whether receipt of dental services, among attenders, reflects variations in dental health or whether and to what degree it is associated with socioeconomic status, with irregular or regular dental attendance and with the availability of dentists in residential areas. Materials and methods. This retrospective register-based study followed two Danish cohorts, aged 25 and 40, with a dental examination in 2009 (n = 32,351). The dental service data were registered during 2005–2009. The number of dental examinations, individual preventive services (IPS), tooth extractions, root fillings and composite fillings were analyzed in relation to socioeconomic status, irregular/regular dental attendance, inhabitant/dentist ratio and to DMFT at age 15 (DMFT15) and change in DMFT (ΔDMFT) from age 15 to age 25 and age 40, respectively. Poisson regression and negative binomial regression analyses were used. Results. The variations in number of services received in the study population were small (SD = 0.2–2.7). However, with a few exceptions, high levels of DMFT15 and ΔDMFT were associated with receipt of more dental services. Socioeconomically-privileged individuals received more dental examinations but fewer tooth extractions, root fillings and composite fillings compared to disadvantaged persons, when controlled for dental health levels. Irregular attenders received fewer IPS and composite fillings but had more extractions compared to regular attenders. Conclusions. Variations in dental care services were found to reflect variations in dental health, but the variations were also related to individual socioeconomic status, residential area and dental attendance patterns.
