Objectives

Differentiated assessment of pits and fissures in permanent molars to get information regarding their need of preventive care during a follow-up of 2 years of 8-year-old Westphalian children

Material and Methods

STUDY POPULATION

  • 369 Westphalian children born in 1989
  • First examination at the age of 8 years in 1997
  • Second examination at age of 10 years in 1999

METHODS

  • Scoring of caries lesions - dft/s/ DMFT/S - according WHO criteria (1997)
  • Scoring of Brown spots, White spots and Microcavities on fissures and pits of the first permanent molars
  • Evaluation of the quality of fissures/pits sealants

Results

Fig. A - G

Fig. A:
Number of caries-free children
Fig. B:
Lorenz curves revealed that nearly 100 % of all cariously affected surfaces were concentrated in 20 % of the children
Fig. C:
Caries prevalence in the primary dentition 70 % of all carious lesions were not restored in 8-yr-olds in 1997 58 % of all carious lesions were not restored in 10-yr-olds in 1999
Fig. D:
Caries prevalence in the permanent dentition 50 % of all carious lesions were not restored in 8-yr-olds in 1997 24 % of all carious lesions were not restored in 10-yr-olds in 1999
Fig. E:
Concentration of caries experience on fissures and pits of the first molars
Fig. F:
Clinical status of occlusal surfaces in first molars Initial carious lesion increased up to 36 % in children of 8 to 10 years of age
Fig. G:
Clinical status of upper palatal/ lower buccal pits in first molars Initial carious lesion increased of 18 % in the 8-yr-olds to 27% in the 10-yr-olds, sealed pits were hardly found

Conclusions

  • Carious lesions in the primary and permanent dentition should be restored.
  • According to increasing numbers of non-cavitated lesions sealants should be applied more frequently in pits and fissures.
  • Sealant application financed by insurance companies since 1993 for 6- to 17-yr-olds are highly needed to prevent a further carious attack of pits and fissures.
