The same women were re\u2010examined in 1980 and 1992 together with new 38\u2010 and 50\u2010year\u2010old women. The dental examination consisted of questionnaires, clinical and panoramic radiological survey (OPG). The number of teeth, number of root filled teeth (RF) and number of teeth with periapical radiolucencies (PA) were registered. The RF and PA ratios were calculated. Cross\u2010sectional data were analysed by means of <jats:sc>anova<\/jats:sc> and longitudinal data by a general linear model for repeated measures. Sample prevalences were compared and statistical inferences were made with the chi\u2010squared test. In all analysis, the confidence interval (CI) regarded mean difference between groups (95% CI).<\/jats:p><jats:p><jats:bold>Results\u2002<\/jats:bold> The RF and PA ratio decreased over time as well as the frequency of edentulous subjects. Cross\u2010sectional analysis revealed a minor increase in frequency of RF and PA and loss of teeth with age. Longitudinally, loss of teeth was evident in all cohorts. In addition, there was a trend of lower number of teeth with PA, and the RF ratio increased with age.<\/jats:p><jats:p><jats:bold>Conclusions\u2002<\/jats:bold> The prevalence of periapical disease did not increase with age, probably as a result of root canal treatment and extractions. Data showed that the prevalence of RF teeth and teeth with PA decreased for comparable age cohorts during the 24\u2010year follow\u2010up.<\/jats:p>","DOI":"10.1111\/j.1365-2591.2005.00944.x","type":"journal-article","created":{"date-parts":[[2005,3,18]],"date-time":"2005-03-18T13:51:31Z","timestamp":1111153891000},"page":"246-254","update-policy":"https:\/\/doi.org\/10.1002\/crossmark_policy","source":"Crossref","is-referenced-by-count":32,"title":["A 24\u2010year follow\u2010up of root filled teeth and periapical health amongst middle aged and elderly women in G\u00f6teborg, Sweden"],"prefix":"10.1111","volume":"38","author":[{"given":"F.","family":"Frisk","sequence":"first","affiliation":[],"role":[{"role":"author","vocabulary":"crossref"}]},{"given":"M.","family":"Hakeberg","sequence":"additional","affiliation":[],"role":[{"role":"author","vocabulary":"crossref"}]}],"member":"311","published-online":{"date-parts":[[2005,3,18]]},"reference":[{"key":"e_1_2_16_2_1","first-page":"79","article-title":"Rotational panoramic radiography in epidemiologic studies on dental health","volume":"10","author":"Ahlqwist M","year":"1986","journal-title":"Swedish Dental Journal"},{"key":"e_1_2_16_3_1","doi-asserted-by":"publisher","DOI":"10.1080\/000163599428904"},{"key":"e_1_2_16_4_1","doi-asserted-by":"publisher","DOI":"10.1111\/j.1600-9657.1986.tb00135.x"},{"key":"e_1_2_16_5_1","doi-asserted-by":"publisher","DOI":"10.1111\/j.0954-6820.1973.tb10583.x"},{"key":"e_1_2_16_6_1","doi-asserted-by":"publisher","DOI":"10.3109\/02813439709035031"},{"key":"e_1_2_16_7_1","first-page":"64","article-title":"Endodontisk behandling och periapikalstatus","volume":"65","author":"Bergenholtz G","year":"1973","journal-title":"Tandl\u00e4kartidningen"},{"key":"e_1_2_16_8_1","doi-asserted-by":"publisher","DOI":"10.1111\/j.1600-0528.1987.tb00528.x"},{"key":"e_1_2_16_9_1","doi-asserted-by":"publisher","DOI":"10.1111\/j.1365-2591.1993.tb00552.x"},{"key":"e_1_2_16_10_1","doi-asserted-by":"publisher","DOI":"10.1111\/j.1600-9657.1987.tb00631.x"},{"key":"e_1_2_16_11_1","doi-asserted-by":"publisher","DOI":"10.1111\/j.1600-9657.1989.tb00333.x"},{"key":"e_1_2_16_12_1","doi-asserted-by":"publisher","DOI":"10.1111\/j.1600-9657.1992.tb00249.x"},{"key":"e_1_2_16_13_1","doi-asserted-by":"publisher","DOI":"10.1111\/j.1600-9657.1991.tb00434.x"},{"key":"e_1_2_16_14_1","doi-asserted-by":"publisher","DOI":"10.1111\/j.1600-9657.1988.tb00309.x"},{"key":"e_1_2_16_15_1","doi-asserted-by":"publisher","DOI":"10.1111\/j.1365-2591.1995.tb00286.x"},{"key":"e_1_2_16_16_1","first-page":"243","article-title":"Oral health of individuals aged 3\u201380\u2003years in J\u00f6nk\u00f6ping, Sweden in 1973, 1983, and 1993.
