Abstract
|
|
|
Various alloplastic materials have been used on the peridontally diseased osseous defects. Hydroxyapatie, which is used the most common alloplastic material is a non-resorbable form of calcium phosphate. The purpose of the present study was to
evaluate
the clinical effects of dense hydroxyapatite on the human periodontal defects.
For this study, 18 patients with periodontal disease were selected from the patients who visited Kyung Hee Medical center. 27 infrabony defects were used in this study which had deep periodontal pocket more than 4mm, and were similar pattern of
alveolar
bone loss in radiographical findings.
Reconstructive periodontal surgery were performed in each defects. Patients were anesthetized with Lidocaine hydrochloride including epinephrine at 1:80,000. With intrasulcular incision, mucoperiosteal flap were elevated on the defected tooth
respectively. Scaling and root planing on exposed root surface were done with ultrasonic and hand instruments. Periosteal fenestration were performed on the inner wall of infrabomy defects.
Dense hydroxyapatite were mixed with normal saline, and were inserted into the defected area using the amalgam carrier and condenser.
For closing the periodontal flap, interrupted and direct loop suture were used on the intreproximal area respectively. All the margin of the flap were complete covering of the exposed root surface including defected area.
Postoperative management were done as follows: Systemic antibiotics and anti-inflammatory agent were administrated for 2 week after surgery. Seven days after surgery, the periodontal pack were removed and repacked for 1 more week. Daily mouth
rinsing
with 0.12% Chlorhexidine gluconate were recommended for 2 weeks.
Clinical parameters, gingival recession, pocket depth, attachment loss were examined before and after surgery.
@ES The results were as follows.
EN 1) dense hydroxyapatite was bioinert and good result in the treatment of infrabony defect.
2) Amount of gingival recession was 0.46±0.31 mm at 3 months and 0.86±0.28mm at 6months.
3) Initial amount of pocket depth of the infrabony defects treated with dense hydroxyapatite was 5.13±0.28mm.
After insertion of graft materials was 3.15±0.14 mm at 3 months and 2.59±0.58mm at 6 months.
4) Mean value of amount of attachment loss is 1.05±0.29mm at 3 months & 1.88±0.75mm at 6 months.
5) No side effects was observed after insertion of dense hydroxyapatite during this study.
