中文摘要 | 氫氧化鈣是常用根管內藥物。臨床用以調拌氫氧化鈣的溶劑種類常依個人而異,然而各式各樣電子根管長度測定器,亦可能因為根管內部存在之物質而影響其準確度。故本實驗之目的在探討不同氫氧化鈣製劑,是否對根管長度測定器之準確度造成影響。包括:(1)局部麻醉劑(2)甘油(3)0.9%生理食鹽水(4)蒸餾水(distilled water)(5)Vitapex五種臨床常用的氫氧化鈣糊劑。分別以Root ZX及Endodontic meter S-Ⅱ兩種根管長度測定器,對置藥前、置藥後及沖洗後檢測。結果顯示:當以Root ZX測量時,無論置藥前、置藥後及沖洗後對根管長度測定器之準確度無造成明顯影響(p<0.05,ANOVA);當 Endodontic meter S-Ⅱ測量時,只有Vitapex置藥後及沖洗後之準確度會造成明顯影響 (p<0.05,ANOVA)。所以利用Vitapex作為根管用藥時,應避免使用Endodontic meter S-Ⅱ來測定根管長度。 |
英文摘要 | Calcium hydroxide has been considered to the material of chocie as intracanal medicament. This study clarified why the type of vehicle is so important. Electronic root canal length measuring devices are affected by the material used in the root canals. The aim of this study was to examine the effect of calcium hydroxide paste dressing on accuracy of the electonic root canal lengthe measurements. Fifty recently extracted human anterior teeth were cleaned and shaped. They were randomly divided into five groups and medicated with calcium hydroxide pastes. The five differnet vehicles included anesthesia, glycerin, normal saline, distilled water and Vitapex. The study measured the root length with the Root ZX and the Endodontic meter S-Ⅱ during premedication, post-medication with calcium hydroxide pastes and after-irrigation with normal saline and 3% hydrogen peroxide. There was no statistically significant difference when using the Root ZX to measure root canal length; but the measurements with the Endodontic meter s-Ⅱ have statically significant difference (p<0.05, ANOVA) during post-medication and after irrigation with Vitapex. |
