慢性歯周炎のスケーリング・ルートプレーニング(SRP)におけるレーザーのプロービングデプス(PD)減少を、ネットワークメタ解析(NMA)により系統的に評価することを目的とした。2020年1月までのランダム化比較臨床試験(RCT)を電子検索およびハンドサーチにより検索した。PD減少については標準平均差(SMD)と95%信頼区間(CI)をカウントした。ランダム効果NMAは、STATAソフトウェア(バージョン13)のmvmetaルーチンを用いて実施した。このNMAでは、37のRCTを通じて7つの歯周治療を分析した。矛盾は認められなかった。機械的SRPと比較し、3ヵ月時点では補助療法としてのダイオードレーザー(DL)(SMD=0.61;95%CI範囲:0.27-0.96)および補助療法としてのNd:YAG(SMD=0.29;95%CI範囲:0.03-0.55)、Er,Cr:YSGG単独療法(SMD=0.37;95%CI範囲:0.04-0.71)、Er,Cr:YSGG併用療法(SMD=0.53;95%CI範囲:0.23-0.84)であった。Er:YAG単独療法と比較すると、治療後6ヵ月目ではDL併用療法に有意差が認められた(SMD=0.51;95%CI範囲:0.07-0.95)。3ヵ月後のPD減少のランキングでは、良い方からNd:YAG併用療法、DL併用療法、Er:YAG併用療法、Er,Cr:YSGG単剤療法、Er:YAG単剤療法、機械的SRPであった。6ヵ月後のPD減少率では、DL併用、Nd:YAG併用、Er:YAG併用、Er,Cr:YSGG併用、Er:YAG単剤、Er,Cr:YSGG単剤、機械的SRPの順であった。レーザーアシスト歯周治療はPDをより減少させた。
The aim was to systematically evaluate the probing depth (PD) reduction of lasers in scaling and root planing (SRP) of chronic periodontitis by network meta-analysis (NMA). Randomized controlled clinical trials (RCTs) were searched through electronic-search and hand-search up to January 2020. Standard mean different (SMD) and 95% confidence interval (CI) were counted for PD reduction. The random-effects NMA were performed using mvmeta routine in STATA software (version 13). This NMA analysed seven periodontal treatments through 37 RCTs. No inconsistency was detected. Compared with mechanical SRP, significant differences were in favour of diode laser (DL) as adjunct at 3 months (SMD = 0.61; 95% CI range: 0.27-0.96) and Nd:YAG as adjunct (SMD = 0.29; 95% CI range: 0.03-0.55), Er,Cr:YSGG as monotherapy (SMD = 0.37; 95% CI range: 0.04-0.71) and Er,Cr:YSGG as adjunct (SMD = 0.53; 95% CI range: 0.23-0.84) at 6 months after treatment. Compared with Er:YAG as monotherapy, significant differences were in favour of DL as adjunct at 6 months (SMD = 0.51; 95% CI range: 0.07-0.95) after treatment. In terms of PD reduction at 3-month follow-up, the ranking result from best to worst was Nd:YAG as adjunct, DL as adjunct, Er:YAG as adjunct, Er,Cr:YSGG as monotherapy, Er:YAG as monotherapy and mechanical SRP. In terms of PD reduction at 6-month follow-up, the ranking result was DL as adjunct, Nd:YAG as adjunct, Er:YAG as adjunct, Er,Cr:YSGG as adjunct, Er:YAG as monotherapy, Er,Cr:YSGG as monotherapy and mechanical SRP. Laser-assisted periodontal treatment has better PD reduction.
