[The effect of pulp extirpation on the function of the hard dental tissues].

The authors analyze the results of clinical and experimental studies of the status of hard dental tissues before and after pulp removal. The findings evidence that Ca and P levels reduce and O2 and oxide levels increase in the hard tissues of pulpless teeth, this probably resulting in changed color and friability of pulpless teeth. These data may be useful in dental surgery when forming carious cavities in pulpless teeth and in orthodontics to make pulp insertions with due consideration for the friability of pulpless teeth.
