Abstract
(1) The technique of eradicating the pockets and occasionally trimming the alveolar margin is described. (2) Instruments designed for the operation are illustrated. (3) The whole mouth can be treated at one sitting. (4) The flap operation, in which the gum is reflected before scraping the alveolus and finally sutured, is not advisable. (5) Pyorrhœa can be eradicated by surgical measures in cases favourable for treatment. (6) Recurrence of the disease is due to: (a) Lack of suitable preliminary treatment. (b) Insufficient attention to detail when performing the operation. (c) Lack of suitable post-operative care by dental surgeon or patient. (d) Selection of cases not suitable for operation.
