Body Mass Index (BMI), caries and erosion in 15 years Icelandic teenagers

Abstract
Objectives: The Oral Health Survey in Iceland (2005) revealed a high prevalence of erosion in permanent teeth and increasing levels of caries in 15-year olds. Data from participants on consumption of soft drinks and measurement of Body-Mass Index (BMI) enabled a study of interaction of lifestyle factors in these two dental diseases. The aim was to investigate the interaction of aetiological factors in erosion and caries so that preventive policies could be developed. Methods: Erosion was recorded (modified scale of Lussi), and caries (D3MFT) determined using The International Caries Detection and Assessment System (ICDAS). Detailed information on consumption of acidic drinks was obtained by questionnaire. Body Mass Index (BMI) was calculated following measurements at the clinical examination. Results: There was a linear relationship between the frequency of consumption of acidic drinks and the proportion of the sample with tooth erosion. Erosion was evident in 30%, significantly more often in boys. The average number of teeth with erosion increased steadily with increased frequency of consuming acidic drinks. There was a parallel increase in the D3MFT index and BMI whereas the number of teeth with erosion present declined with increasing BMI in boys. Conclusion: There are different associations between BMI and caries and BMI and erosion.
Markmið: Upplýsingar liggja fyrir um tannheilsu og lífsstíl nemenda í 10. bekk íslenskra grunnskóla í rannsókn á munnheilsu íslendinga frá árinu 2005 (MUNNÍS). Gögn um tíðni á tannátu (caries) og glerungseyðingu (erosion), neyslu gosdrykkja ásamt mælingu á hæð og þyngd einstaklinga gáfu möguleika á að skoða tengsl þessara tveggja tannsjúkdóma við holdafar (BMI) einstaklinga og gosdrykkjaneyslu þeirra. Markmið þessarar rannsóknar var að skoða tengsl tannátu og glerungseyðingar við holdafar með forvarnir í huga. Efniviður: Nemendur voru valdir með tilviljunarkenndu klasaúrtaki (random cluster sample) sem í voru um 20% nemenda í 10. bekk, 384 piltar og 366 stúlkur, samtals 750. Glerungseyðing var greind eftir staðsetningu og alvarleika (modified scale of Lussi). Tannáta var greind eftir D3MFT með The International Caries Detection and Assessment System (ICDAS). Með spurningalista var aflað upplýsinga um neyslu á gosdrykkjum. Holdafar var mælt með skoðun á hæð og þyngd. Niðurstöður: Glerungseyðing greindist hjá 30% 15 ára unglinga, piltar voru með martækt meiri glerungseyðingu en stúlkur (38.3% pilta, 22.7 % stúlkna, p<0.001). Stúlkur og piltar voru að meðaltali með 4.24 tennur skemmdar (D3MFT). Tengsl eru á milli aukinnar neyslu gosdrykkja og meðalfjölda tanna með glerungseyðingu. Jákvæð fylgni er á milli tannátu (D3MFT) og líkamsþyngdar (BMI) en neikvæð fylgni á milli glerungseyðingar og holdafars. Ályktun: Mismunandi tengsl eru á milli holdafars og tannátu og holdafars og glerungseyðingu.
