ProGliderは, モーター駆動式ハンドピースに装着して使用することで適確なグライドパスの形成が期待されている. 本研究は, ProGliderによるグライドパス形成後の根管追従性や形成能を明らかにすることを目的として根管壁変位量を測定し, さらにグライドパス形成後のNi-Tiファイルによる根管形成への影響を比較し, ProGliderの切削特性を解析した. <br> 材料と方法 : エポキシレジン製J型湾曲根管模型60本を使用した. グライドパスの根管壁切削量の比較は#15, #20Kファイル群とProGlider群に分類して測定した. グライドパス形成後のNi-Tiファイルによる根管形成への影響は, WaveOne, ProTaper Nextを使用し, 各群ともにKファイルとProGliderによるグライドパス形成後に根管壁切削量を比較検討した. 根管壁切削量の測定は, デジタル画像解析にて根尖孔から1, 3, 5, 8mmの位置で内・外湾側の根管幅径増加量を計測し, 統計処理を行った. <br> 結果 : グライドパスの根管幅径増加量は, Kファイル群がProGlider群と比較して内湾側3mmの位置で有意に増加した. KファイルおよびProGliderによるグライドパス形成後のNi-Tiファイルによる根管幅径増加量を測定した結果, WaveOneで内・外湾側3mmの位置でKファイル群がProGlider群と比較して有意に増加傾向が示された. しかしながらProTaper Nextでは, Kファイル群とProGlider群による根管幅径増加量に有意差は認められなかった. <br> 結論 : ProGliderによるグライドパス形成は湾曲根管内湾部のトランスポーテーションを抑制し, グライドパス形成後のNi-Tiファイルによる根管形成においても, 本来の根管形態を正確に維持することが示された.","subitem_description_type":"Abstract"},{"subitem_description":"Purpose: Root canal shaping by nickel-titanium (Ni-Ti) is one of the most important steps in creating a glide path. However, it is not easy to control the original canal shaping by a manual glide path. The ProGlider single-file system (Dentsply Maillefer, Switzerland) was recently introduced for performing a mechanical glide path. This study was designed to analyze the shaping ability by ProGlider, and also evaluate the influence of canal shaping with WaveOne (Dentsply Maillefer) and ProTaper Next (Dentsply Maillefer) after shaping the glide path.<br> Methods: Sixty Endo Training block canals (Dentsply Maillefer) were used, divided according to the glide path system and Ni-Ti rotary system used for canal preparation into 6 groups of 10 samples each: K-file, ProGlider, K-file & WaveOne, ProGlider & WaveOne, K-file & ProTaper Next, ProGlider & ProTaper Next groups. Canal transportations were assessed by comparing the pre-instrumentation and post-instrumentation images under an Olympus ZX16 with DP71 digital camera, and the superimposed images were analyzed using WinROOF. Data were statistically analyzed with the significance level set at p<0.05.<br> Results: The glide path of ProGlider exhibited a significantly lower mean of canal transportation than manual K-File. It was shown that significantly lower deviation occurred by ProGlider & WaveOne than K-file & WaveOne. There was no significant difference between the K-file & ProTaper Next and ProGlider & ProTaper Next groups in canal transportation (p<0.05).<br> Conclusions: This study confirmed the ability of ProGlider to reduce transportation, and the WaveOne and ProTaper Next Ni-Ti system can yield better performance with fewer problems compared with instrumentation performed with K-file.","subitem_description_type":"Abstract"}]},"item_10006_dissertation_number_12":{"attribute_name":"学位授与番号","attribute_value_mlt":[{"subitem_dissertationnumber":"乙第505号"}]},"item_10006_heading_21":{"attribute_name":"見出し","attribute_value_mlt":[{"subitem_heading_headline":"※セキュリティ設定あり","subitem_heading_language":"ja"}]},"item_10006_relation_14":{"attribute_name":"情報源","attribute_value_mlt":[{"subitem_relation_name":[{"subitem_relation_name_text":"日本歯科保存学雑誌, 58(4):265-272, 2015"}]}]},"item_10006_relation_15":{"attribute_name":"関連サイト","attribute_value_mlt":[{"subitem_relation_name":[{"subitem_relation_name_text":"J-STAGE"}],"subitem_relation_type_id":{"subitem_relation_type_id_text":"https://www.jstage.jst.go.jp/article/shikahozon/58/4/58_265/_article/-char/ja","subitem_relation_type_select":"URI"}}]},"item_10006_rights_13":{"attribute_name":"権利","attribute_value_mlt":[{"subitem_rights":"日本歯科保存学会"},{"subitem_rights":"神奈川歯科大学リポジトリ以外への転載には、再度、日本歯科保存学会へ登録を要する。"}]},"item_10006_version_type_18":{"attribute_name":"著者版フラグ","attribute_value_mlt":[{"subitem_version_resource":"http://purl.org/coar/version/c_970fb48d4fbd8a85","subitem_version_type":"VoR"}]},"item_access_right":{"attribute_name":"アクセス権","attribute_value_mlt":[{"subitem_access_right":"open access","subitem_access_right_uri":"http://purl.org/coar/access_right/c_abf2"}]},"item_creator":{"attribute_name":"著者","attribute_type":"creator","attribute_value_mlt":[{"creatorNames":[{"creatorName":"秋山, 勝彦","creatorNameLang":"ja"},{"creatorName":"アキヤマ, カツヒコ","creatorNameLang":"ja-Kana"}],"nameIdentifiers":[{"nameIdentifier":"5","nameIdentifierScheme":"WEKO"}]},{"creatorNames":[{"creatorName":"Akiyama, Katsuhiko","creatorNameLang":"en"}],"nameIdentifiers":[{"nameIdentifier":"2433","nameIdentifierScheme":"WEKO"}]}]},"item_files":{"attribute_name":"ファイル情報","attribute_type":"file","attribute_value_mlt":[{"accessrole":"open_date","date":[{"dateType":"Available","dateValue":"2016-07-26"}],"displaytype":"detail","filename":"otsu505_fulltext.pdf","filesize":[{"value":"418.6 kB"}],"format":"application/pdf","licensetype":"license_11","mimetype":"application/pdf","url":{"label":"Full Text（全文）","objectType":"fulltext","url":"https://kdu.repo.nii.ac.jp/record/10/files/otsu505_fulltext.pdf"},"version_id":"efa6e375-bb8c-445f-8b7c-abd8fbceae06"},{"accessrole":"open_date","date":[{"dateType":"Available","dateValue":"2016-04-06"}],"displaytype":"detail","filename":"otsu505_summary.pdf","filesize":[{"value":"122.0 kB"}],"format":"application/pdf","licensetype":"license_11","mimetype":"application/pdf","url":{"label":"論文内容要旨","url":"https://kdu.repo.nii.ac.jp/record/10/files/otsu505_summary.pdf"},"version_id":"9da6bf25-3806-4652-8c02-1f92c31d5be8"},{"accessrole":"open_date","date":[{"dateType":"Available","dateValue":"2016-04-06"}],"displaytype":"detail","filename":"otsu505_thesisreview.pdf","filesize":[{"value":"208.8 kB"}],"format":"application/pdf","licensetype":"license_11","mimetype":"application/pdf","url":{"label":"論文審査要旨、最終審査の結果の要旨","url":"https://kdu.repo.nii.ac.jp/record/10/files/otsu505_thesisreview.pdf"},"version_id":"55e597be-b658-4f65-9544-0da6a9a4e9ae"}]},"item_language":{"attribute_name":"言語","attribute_value_mlt":[{"subitem_language":"jpn"}]},"item_resource_type":{"attribute_name":"資源タイプ","attribute_value_mlt":[{"resourcetype":"doctoral thesis","resourceuri":"http://purl.org/coar/resource_type/c_db06"}]},"item_title":"ProGliderのグライドパスがNi-Tiファイルによる根管形成に及ぼす影響に関する研究","item_titles":{"attribute_name":"タイトル","attribute_value_mlt":[{"subitem_title":"ProGliderのグライドパスがNi-Tiファイルによる根管形成に及ぼす影響に関する研究","subitem_title_language":"ja"},{"subitem_title":"Evaluation of Root Canal Shaping Associated with Nickel-titanium File System by Glide Path of ProGlider","subitem_title_language":"en"}]},"item_type_id":"10006","owner":"10","path":["7"],"pubdate":{"attribute_name":"PubDate","attribute_value":"2016-04-06"},"publish_date":"2016-04-06","publish_status":"0","recid":"10","relation_version_is_last":true,"title":["ProGliderのグライドパスがNi-Tiファイルによる根管形成に及ぼす影響に関する研究"],"weko_creator_id":"10","weko_shared_id":-1},"updated":"2023-12-21T01:23:46.120799+00:00"}
