title: Gingival enhancement in fixed prosthodontics. Part I: Clinical findings.
abstract: This study assessed the efficacy of a 0.12% chlorhexidine gluconate (CHX) rinse on the enhancement and maintenance of gingival health in patients receiving fixed prosthodontic treatment. Thirty patient participants in this examiner blind study were randomly assigned into two groups, one control and another group using CHX 15 ml b.i.d. in addition to normal oral hygiene. The medication was used for 2 weeks prior to crown preparation, 3 weeks during provisional crown placement, and 2 weeks after definitive crown cementation. Plaque and gingivitis indices were measured initially and at the three aforementioned points during the 7-week period. The plaque index for the control group decreased by 0.26 units; CHX decreased by 0.63 units at 7 weeks. The gingival index of the control group decreased by 0.37 units; CHX decreased by 0.87 units. Adjunctive use of chlorhexidine with fixed prosthodontic procedures significantly reduced plaque levels and significantly improved gingival health compared with the control patients. Fixed prosthodontic procedures alone decreased plaque levels and increased gingival health.
