Presence of Cementum in Man dependent upon Abnormal Influence.—But in those teeth where there has been some abnormal influence in opera- tion, whether arising from any undue stimulus exciting the dentine to a rapid development, or from a sluggish or defective action in the power of the enamel-pulp to fulfil its object, which naturally becomes more feeble as it approaches completion, it follows that the more defective will be the enamel; and we have every right to infer that, in extreme cases, some portion of the enamel organ may remain undeveloped, and assume the character of true cementum as it appears in the lower animals. I have never met with this condition of the structure myself, but corpusculated cementum, under such circum- stances, has been observed by Perkinje* and Tomes, f 27. Cementum resulting from Injury during the Development of Enamel.—Although I have never seen a corpusculated structure, yet I have ob- served its presence under parallel circumstances. * Owen, “ Introduction to Odontography,” p. 12. f Tomes, “ Manual of Dental Surgery,” p. 271.
