. Elementary and dental radiography / by Howard Riley Raper . iately began to wonder whether or not I was about to discover an authentic caseof congenital absence of a first molar. I say authentic, because in records of this 152 DENTAL RADIOGRAPHY kind it is not always that one may be sure that the history is authentic. But inthis particular case there can be no doubt.
