The importance of basic periodontal treatment In patients with mild periodontitis, after basic periodontal treatment, the periodontal pockets can become shallow or disappear in most patients, and the periodontal tissues can be restored to health and go directly to the long-term periodontal maintenance phase. For moderate to severe periodontitis, after basic periodontal treatment, the inflammation can basically subside and the periodontal pockets become shallow, but deep periodontal pockets can still remain, which usually requires further periodontal surgical treatment, in addition, it also usually requires multidisciplinary combined treatment such as endodontic, restorative and orthodontic treatment. At the same time, periodontal basic treatment is also the prerequisite and foundation for periodontal surgical treatment and other oral related treatments, such as restorative and orthodontic treatment. For example, patients with periodontitis must undergo periodontal basic treatment before restorative treatment to facilitate the precise fabrication of restorations and to prevent further destruction of the periodontal condition of the remaining teeth. Even in patients without periodontal disease, if more tartar is present, periodontal base treatment is required to ensure the accuracy of the restorative impressions. Periodontal basic treatment is also needed before some major intra-oral surgeries to eliminate the potential risk of infection; periodontal basic treatment is also needed before and during orthodontic treatment to ensure gum health and prevent periodontal destruction. The main contents of periodontal basic treatment include: 1.Education of patients on the causes of periodontal disease, instruction of patients on the methods of self-control of plaque, learning to use oral cleaning tools, such as toothbrush, dental floss and the correct use of interdental brushes, etc.; 2.Extraction of affected teeth without retention value; 3.Implementation of scaling, scraping, root surface leveling, etc. to eliminate plaque and tartar; 4.Elimination of plaque retention factors, such as misalignment of teeth, overhang, cavities, bad cavities, etc. 5.After the inflammation is controlled, the necessary occlusion adjustment can be made, and if necessary, the temporary loose teeth can be fixed; 6.Auxiliary medication can be used when necessary. Considerations for basic periodontal treatment To successfully perform basic periodontal treatment, clinicians must pay attention to basic periodontal treatment on the one hand, and master some skills on the other hand, including proper screening of patients, selection of appropriate examination methods and making correct diagnosis. Finally, the clinician must also use standardized practices to complete basic treatment, all of which require specialized and standardized training to master.
