case_images: Clinic, Faculty of Dentistry, Chiang Mai University, because of pain in the lower left quadrant upon eating and upon drinking cold liquids. Clinical examination revealed a large carious lesion involving the occlusal and buccal surfaces of the left mandibular permanent first molar (Figure 1(a)). The bleeding was controlled with 2.5% NaOCl-moistened cotton pellets within four minutes (Figure 1(b)). Biodentine  was allowed to initially set for 12 minutes (Figure 1(c)). Finally, the cavity was filled with resin composite (Filtek  Z350 XT; 3M ESPE) and light cured for 40 seconds for each surface, followed by the finishing and polishing procedures (Figure 1(d)). The colour stability of the tooth was noted (Figure 1(e)).
case_images: Periapical radiographs recorded (a) before treatment, (b) immediately after treatment, (c) six months postoperative, and (d) five years postoperative, showing dentine bridge and improvement of the periapical area.

case_images: A periapical radiograph showed a deep carious lesion in close proximity to the pulp and periapical lesion, including loss of lamina dura, widened periodontal ligament space, and condensing osteitis (Figure 2(a)). A periapical radiograph was recorded immediately after treatment (Figure 2(b)). The follow-up periapical radiographs showed a dentine bridge and periapical healing (Figures 2(c) and 2(d)).
case_images: Bitewing radiographs recorded (a) three years postoperative, (b) four years postoperative, and (c) five years postoperative, showing dentine bridge in the left mandibular permanent first molar.
