Abstract
A clinical trial was performed to study the result of periodontal treatment following different modes of periodontal surgery in patients not recalled for maintenance care. The material consisted of 25 patients distributed into 5 groups. Following an initial examination, all patients underwent presurgical treatment including case presentation and instruction in oral hygiene measures. This instruction was given once. Various patient groups were then subjected to 1 of the following sugical procedures: the apically repositioned flap operation including elimination of bony defects, the apically repositioned flap operation including curettage of bony defects but without removal of bone, the Widman flap technique including elimination of bony defects, the Widman flap technique including curettage of bony defects but without removal of bone and gingivectomy including curettage of bony defects but without removal of bone. Six, 12 and 24 mo. after completion of treatment, patients were recalled for assessment of their oral hygiene standard and periodontal conditions. Case presentation and oral hygiene instruction given once apparently only temporarily improved the patient''s oral hygiene habits. Renewed accumulation of plaque in operated areas resulted in recurrence of periodontal disease including a significant further loss of attachment. All 5 different techniques for surgical pocket elimination were equally ineffective in preventing recurrence of destructive periodontitis.
