Synonyms Chronic parenchymatous pulpitis; atrophy of thepulp, pulpitis chronica parenchymaiosa, atrophia pvlpce. Definition. Chronic parenchymatous degeneratiou of the pulp. Etiology. Atrophy of the pulp is primarily caused by naturalsenile, retrogressive, metamorphotic changes within the pulp tissueIndependently of inflammatory processes. Pathologists recognizeamyloid, atrophic, Patty, fibroid and calcareous varieties. Clinical Pathology. In the absence of any recognizable symptomsof the unexposed pulp there is no clinical picture to be Fig. 71.—Degeneration of the dental pulp Pathologically, degeneration of the pulp is most frequently , rather commonly met with in the teeth of the aged;it i^ an eminently chronic process. It maj be restricted to theperiphery of the pulp: usually, however, it involves the wholeorgan. The degenerated pulp presents the typical picture of aretrogressive metamorphosis, t. e., dilated bloodvessels, degen-erated nerve fibers, reticular atrophy or adenoid degeneration ofits connective tissue and reduction of the size of the various types of degeneration present definite patholphases, which are onl\ recognizable microscopically. As the elm- DEGEXERATIOX OF THE DENTAL PULP 139 ical practitioner cannot diagnose atrophy of the pulp in situ, anex cathedra discussion of its pathology would prove of little serviceto him.
