目的は、進行した歯周病に対して4MATRIXと4MATRIXとPRFを併用し、6ヶ月、12ヶ月、18ヶ月の経過観察で歯周ポケット深さ(PPD)と臨床付着レベル(CAL)を改善する効果を比較することであった。
AIM: The aim was to compare the effect in improvement of periodontal pocket depth (PPD) and clinical attachment level (CAL) between application of 4MATRIX and 4 MATRIX combined with PRF in advanced periodontal disease during follow-up of 6, 12 and 18 months.
方法:
25~50歳の男女30名の患者を対象とした。患者は、臨床的および放射線学的に、上顎に深さ5mm以上の歯周ポケットが存在する全身性の進行性慢性歯周炎と診断された。全例で両側ともフラップ治療が行われた.片側には骨補填材4MATRIXを適用し,もう片側には4MATRIXとPRFを適用して治療した.臨床評価と測定は、介入直前、介入後6、12、18ヶ月の4段階で行われた。PPDとCALは、4つの時点すべてで測定された。
METHODS: Thirty patients of both genders aged 25-50 years were included. The patients were clinically and radiologically diagnosed with generalized advanced chronic periodontitis with the presence of periodontal pockets with a depth of ≥ 5 mm bilaterally in the upper jaw. Both sides were treated with a flap intervention in all patients. On one side a bone substitute 4MATRIX was applied, and the other side was treated with an application 4MATRIX and PRF. The clinical assessment and measurements were performed in four stages, immediately before the intervention, and then 6, 12 and 18 months after the intervention. PPD and CAL were determined in all four timepoints.
結果:
PPDは両群とも手術前ゼロの時が最も高く、5.56±0.28mmであった。術後の経過観察期間では、PPDの値は徐々に減少し、18ヶ月後の平均値はI群で5.10±0.18mm、II群で4.67±0.13mmと最も低かった(それぞれ、p<0.001)。さらに、術後6ヶ月、12ヶ月、18ヶ月のPPDの値を比較すると、4MATRIXと4MATRIX+PRFの患者間で有意差が認められた(それぞれp<0.001)。術後の経過観察期間では、CAL値は減少し、18ヶ月後に最も低い値を示した。4つの測定時期でCALに有意な差が見られた(それぞれp<0.001)。CALの平均値は、両群とも外科的治療前が最も高い値であった。18ヶ月後のCALのグループ間分析では、I群(4MATRIX)は5.27±0.17mm、II群は4.10±0.14mm(p<0.001)であった。
RESULTS: PPD was the highest at zero time before the surgery for both groups and was 5.56 ± 0.28 mm. In the postoperative follow-up period, the PPD value decreased gradually with the lowest average value of 5.10 ± 0.18 mm after 18 months in Group I and 4.67 ± 0.13 mm in Group II (p < 0.001, respectively). Moreover, comparing the values of PPD at 6, 12 and 18 months after the surgery, a significant difference was found between the patients from the 4MATRIX vs 4MATRIX + PRF (p < 0.001 respectively). The postoperative follow-up period showed a decrease in CAL value with the lowest value after 18 months. A significant difference in CAL was found between the four measurement times (p < 0.001, respectively). The average level of CAL was the highest before surgical treatment in both groups. The intergroup analysis of CAL after 18 months in group I (4MATRIX) was 5.27 ± 0.17 mm and in group II 4.10 ± 0.14 mm (p < 0.001).
結論:
4MATRIXおよび4MATRIX+PRFを用いた上顎の両側5mm以上の歯周ポケットを有する進行性慢性歯周炎成人患者に対する治療では、治療開始18ヵ月後にPPDの改善とCALロスの低下が認められた。4MATRIX+PRFの治療群では、PPDとCALロスの改善度が最も高かった。4MATRIXと4MATRIX+PRFを併用した場合、投与18ヵ月後に最も低い値を示しました。
CONCLUSION: Treatment of adult patients with advanced chronic periodontitis with periodontal pockets of ≥ 5 mm bilaterally in the upper jaw using 4MATRIX and 4MATRIX + PRF showed improvement of PPD and lower CAL loss after 18 months of the treatment. In the group treated with 4MATRIX + PRF patients showed the highest improvement in PPD and CAL loss. The analysis of treatment with 4MATRIX and 4MATRIX + PRF showed the lowest values after 18 months of the treatment.
