  1. SD, standard deviation; vit., vitamin; GBI, Gingival Bleeding Index; DI-S, Debris Index simplified (dental bacterial plaque); OHI-S, Oral Hygiene Index simplified
  2. aCaries included dentin caries (grade 3–5, Amarante 1998) and filled teeth in primary second molars and permanent first molars (5 did not have caries registration)
  3. bEnamel defects (Brook et al. 2001, Elcock et al. 2006) include Hypoplasia = areas on the tooth with thin enamel, Opacity = opaque white or yellow hypomineralized areas, Post-eruptive breakdown = loss of enamel after tooth eruption
  4. cDental erosion (Hasselkvist et al. 2010, Johansson et al. 1996) include buccal and lingual surface erosion, and occlusal cupping. Children aged 4–5 and 10–16 years included (2 did not have the examination)
  5. dGBI (Ainamo & Bay, 1975), categorized into two levels; the lowest third and a combination of the middle and highest thirds of GBI scores. Children aged 10–16 years included (3 did not have the examination)
  6. eDI-S (Greene & Vermillion, 1964), categorized into two levels; the lowest third and a combination of the middle and highest thirds of DI-S scores. Children aged 10–16 years included (20 missing as those with fixed orthodontic appliances were excluded in these analysis)
  7. fOHI-S (Greene & Vermillion, 1964) = the sum of Debris Index and Calculus index, categorized into two levels; the lowest third and a combination of the middle and highest thirds of OHI-S scores. Children aged 10–16 years included (20 missing due to fixed orthodontic appliances)
