aThirteen patients could not cooperate for obtaining a panoramic image, therefore 12 patients could be evaluated
bThe patient has also mandibular first primary molar with three roots
cRadicular cyst of left maxillary lateral incisor and impacted right maxillary second premolar are present
dPeriapical lesion of left maxillary lateral incisor, generalized shortened roots and impacted maxillary wisdom teeth are also present
