The change in state dentoalveolar complex out clinically functionally. hygienic index API, papillary bleeding PBI, need periodontal CPITN, gum recession depth probing determined. Laser Doppler flowmetry used assess local blood flow vasomotor activity vessels. studied parameters evaluated start after 14 days. During study, complications side effects not revealed, however, clinical functional indicators indicate that preference should be given gingivoplasty as qualitative preparing
