Second premolarcrowned, imperfect root filling, which, however, extends to apex, periapical regionnormal. First molar pulpless, apparent area of rarefaction about apex of lingualroot, but close scrutiny reveals cancellated bone in this position. A bony promi-nence over this tooth projects into maxillary sinus. Fig. 135.—First premolar shows fracture of root at junction of upper and middlethirds; pulp of this tooth remained vital for several years after fracture.
