case_images: Clinical examination revealed mixed dentition stages, extensive caries of all primary molars, and that the lower left first primary molar (#74) had been restored with defective amalgam restoration (Figure 1) (Canon EOS4000 digital camera was used for all photographic figures). The upper right and left first permanent molars (#16 and #26) had large demarcated opacities, yellowish-brown in color; lower right permanent first molar (#46) had posteruptive enamel breakdown and active caries; lower left permanent first molar (#36) showed posteruptive breakdown and deep mesial active caries (Figure 1), not tender to percussion and with a normal cold-test response (Endo-frost, coltene/whaledent, langenau Germany). Occlusion assessment showed class I molar relationship, and soft tissue examination was within normal limits (Figure 1).

case_images: Radiographic examination showed multiple interproximal caries of primary molars with remaining roots; lower left permanent first molar (#36) with deep mesial caries and immature open apex (Figure 2).

case_images: Radiographic imaging revealed that teeth (#36 and #46) had normal apical tissue, intact lamina dura, and periodontal ligament space, with total apical closure of both mesial and distal root canals of the tooth (#36) which confirmed a short-term success of the treatment (Figure 4C).
