Periodontal surgery in plaque-infected dentitions

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. The various patient groups were then subjected to one of the following surgical procedures: 1) the apically repositioned flap operation including elimination of bony defects 2) the apically repositioned flap operation including curettage of bony defects but without removal of bone 3) the "Widman flap" technique including elimination of bony defects 4) the "Widman flap" technique including curettage of bony defects but without removal of bone 5) gingivectomy including curettage of bony defects but without removal of bone. Six, 12 and 24 months after completion of the treatment, the patients were recalled for assessment of their oral hygiene standard and periodontal conditions. The results showed that case presentation and oral hygiene instruction given once, only temporarily improved the patient's oral hygiene habits. Renewed accumulation of plaque in the operated areas resulted in recurrence of periodontal disease including a significant further loss of attachment. All five different techniques for surgical pocket elimination were equally ineffective in preventing recurrence of destructive periodontitis.
