Restorative treatment and use of local anesthesia in free and subsidized public dental services in Helsinki, Finland

Abstract

Our aim was to evaluate restorative treatment and the use of local anesthetics in free and subsidized public dental care in Helsinki, Finland. Public dental clinics are open to all patients under the age of 36, and to some specific groups above that age. Patients up to age 19 receive all treatment free of charge and others at highly subsidized rates. Data were collected in May 2001 during a maximum 2-week period covering all public dental clinics in Helsinki. A one-page questionnaire was sent to all dentists (n = 140) in clinical fields. The data requested included the patient's gender and year of birth, and details on restorations: which tooth and which surfaces were filled, the reason for placement or replacement, the material used, and use of local anesthetic. The response rate was 96%. Of all restorations (n = 3057) placed, 14% were in primary teeth and in permanent teeth: 17% in premolars, 17% in incisors, and 52% in molars; the restorative material most often used was composite resin (69%). Glass-ionomer/compomers dominated in the primary teeth. Local anesthetic was used least (35%) in patients under 13 years of age. Replacements of restorations accounted for 10% of all in the free service (under 20 years of age) and 46% in subsidized dental care (20 and older). The major reasons for replacement were secondary caries (41%) and fractured or lost restoration (40%).
