[Periodontal function and oral hygiene following an operation for apicoectomy]

The author analyzes the effect of the dental root apex resection on the function of marginal periodontal tissues of the operated on tooth and oral hygiene of 103 patients with chronic periapical foci of odontogenic infection, aged 12 to 53, on the basis of the data of monitoring the changes in the content of gingival fluid, depth of the gingival grooves or pouches, and the Schiller-Pisarev test and hygiene index. The operation in question was found to essentially disorder the biologic equilibrium in the marginal periodontal tissues and to deteriorate the hygienic status of the oral cavity. The developing shifts are reversible and disappear in two weeks after surgery. The author emphasizes that such patients should be timely trained to take care of the oral cavity in order to improve its hygienic status in the postoperative period.
