The Clinical Research Of Medical Nano Hydroxyapatite Treatment Of Peridodntal Disease

Objective This paper aims at the treatment of periodontal disease with medical nano hydroxyapatite, which makes a preliminary discussion about the clinical effect in improving the degree of the loose teeth, the depth of periodontal treatment and the loosing of gum adhesion to explore the new treatment of periodontal disease patients.Methods This paper makes a retrospective analysis of 50 cases of periodontal disease patients of the Department of Stomatology in the fourth affiliated hospital, Guangxi medical university from June, 2009 to December, 2010, according to the different treatment method, who are divided into two groups:(Group A)Pure root surface smooth operation group and ( Group B ) root surface smooth operation + nano hydroxyapatite implant group; each group has 25 cases.The standard of periodontal disease and selecting the object of the study should be clear and definite before operation. The factors which may affect curative effect such as age, systemic disease, periodontal situation and orthodontic correction etc should be excluded so as to eliminate the between-group differences and enhance the comparability. The statistics related with the flossing degree of the teeth, periodontal CPI index and perturbation X-ray examination are recorded respectively in 1, 4, 12 weeks, which carries on the contrast between groups.Results (Group A)Pure root surface smooth operation group of 25 cases,(Group B)Root surface smooth operation + nano hydroxyapatite implant group of 25 cases,postoperative comparison periodontal probing depth, attachment loss values, hydroxyapatite implant was superior to root planning alone group, Statistically significant(P<0.05)。Conclusion Root surface smooth operation + nano hydroxyapatite applied for the treatment of periodontal disease patients implanted little injury to make a postoperative recovery in good conditions, which is the ideal methods that can also improve the periodontal status of periodontal disease patients and worth being clinically further popularized.
