The removal of the odontome is indicated inmost cases. III.—CONNECTIVE TISSUE ODONTOMES This group comprises those odontomes thatarise only from the dental tissues of meso-dermic origin. The classification of odontomesadopted by Sir J. Bland-Sutton was deter-mined by the j)art of the developing tooth thatunder\\ent aberration. The two groups alreadydescribed are due to aberration of the enamel- 761 organ, and although the second group containsa tissue of mesodermic origin, its develojamentis dependent upon that of the present group is due to aberration in deve-lopment of the follicle, and might have been.

The hollowof tlie odontoma contained irregularly calcifiedmaterial. described as follicular odontomes if thisterm had not been used formerly for dentigerouscysts. The name connective tissue odon-tomes introduced by the Committee of theBritish Dental Association appears to be suffi-ciently accurate and comprehensive. As these odontomes are not due to aberrationsof the enamel-organ, they do not contain eitherenamel or dentine. Some specimens that aredescribed as fibrous odontomes and cementomes,and must, as far as present knowledge goes, beincluded among odontomes, contain teeth thatshow a normal development of enamel anddentine, whilst the tissues derived from thefollicles have undergone aberration.
