【摘要】：目的：本文通過病例報告的形式將K3XF機用鎳鈦系統(tǒng)與手用不銹鋼K銼預(yù)備根管的療效進行對比，觀察根管治療期間急癥(IAE)發(fā)生率及疼痛程度情況，為K3XF機用鎳鈦系統(tǒng)的使用提供一定的臨床依據(jù)。 方法：依就診次序，將納入研究的40例牙髓炎患者，隨機分為實驗組和對照組，每組各20例。全部病例身體健康，就診前均未接受任何治療，要求能夠配合治療，且經(jīng)過臨床口內(nèi)檢查和輔助檢查確診為牙髓炎，X線顯示無鈣化根管，同時排除急性根尖周炎、重度牙周病和牙隱裂等疾病，防止影響后期療效的評價。兩組患牙采用的根管治療方法均為多次法。患牙拍術(shù)前X線片，局麻下去凈腐質(zhì)，制備開髓洞型，探尋根管口，，清除已感染的病變牙髓，3%過氧化氫和0.9%生理鹽水徹底沖洗。10#或15#手用不銹鋼K銼探查并建立每個根管通道，通過根管測量儀聯(lián)合比對X線片確定工作長度。實驗組：使用K3XF機用鎳鈦系統(tǒng)結(jié)合冠向下法預(yù)備根管。對照組：手用不銹鋼K銼常規(guī)法預(yù)備根管。每更換一次器均使用3%過氧化氫和0.9%生理鹽水徹底沖洗，預(yù)備結(jié)束，棉卷隔濕，紙尖吸干管腔，導(dǎo)入氫氧化鈣消毒，牙膠條和氧化鋅雙層暫封一周。囑患者如果有疼痛或腫脹情況發(fā)生，立即就診治療。若癥狀輕微，則可以考慮重新更換封藥；若有嚴重癥狀出現(xiàn)，如疼痛加重，局部腫脹等情況發(fā)生時，則及時行CP棉球開放引流，帶癥狀消退后，重新封藥。一周后復(fù)診，記錄患牙根管預(yù)備后疼痛發(fā)生情況。在患者無不適，無明顯叩痛，無大量滲出的前提下，去除原封存，3%過氧化氫和0.9%生理鹽水徹底沖洗，棉卷隔濕，紙尖吸干管腔，導(dǎo)入氧化鋅碘仿糊劑，用牙膠尖側(cè)方加壓充填嚴密。 結(jié)果：在IAE發(fā)生率方面，實驗組IAE發(fā)生率是5%，對照組IAE發(fā)生率是35%，兩組IAE發(fā)生率差異具有統(tǒng)計學(xué)意義（P0.05）；在疼痛程度方面，兩組在疼痛程度為Ⅱ級時差異具有統(tǒng)計學(xué)意義（P0.05），實驗組優(yōu)于對照組。在疼痛程度為0級、Ⅰ級和Ⅲ級時差異無統(tǒng)計學(xué)意義（P0.05）。 結(jié)論：通過使用K3XF機用鎳鈦系統(tǒng)與手用不銹鋼K銼預(yù)備根管，顯示K3XF機用鎳鈦系統(tǒng)在IAE發(fā)生率及疼痛程度為Ⅱ級方面明顯低于手用不銹鋼K銼。在臨床使用中，K3XF機用鎳鈦系統(tǒng)有較好的發(fā)展前景。
[Abstract]:Objective: to compare the curative effect of K3XF machine nickel titanium system with hand stainless steel K file in root canal preparation by case report, and to observe the incidence of acute disease and the degree of pain during root canal therapy. To provide certain clinical basis for the use of K 3 XF machine nickel titanium system. Methods: 40 patients with pulpitis were randomly divided into experimental group and control group with 20 cases in each group. In addition, the diagnosis of pulpitis by clinical intraoral examination and auxiliary examination showed that there were no calcified root canals on X-ray, and acute periapical periodontitis, severe periodontal disease and tooth cleft were excluded. Two groups of teeth were treated with multiple methods of root canal treatment. X-ray films were taken before operation, local anaesthesia was used to purify rot, pulp opening cavity was prepared, and root canal orifice was explored. Remove 3% hydrogen peroxide and 0.9% normal saline from infected pulp and thoroughly flush .10# or 15# hand stainless steel K file to explore and establish each root canal, The working length was determined by the combination of root canal measuring instrument and X ray film. Experimental group: root canal was prepared by using K3XF machine with nickel-titanium system combined with crown down method. Control group: hand stainless steel K file routine method for root canal preparation. All of them were washed thoroughly with 3% hydrogen peroxide and 0.9% normal saline. At the end of preparation, the cotton is wetted, the paper tip absorbs the tube cavity, the calcium hydroxide is introduced into the cavity, the dental gum strip and zinc oxide are temporarily sealed for a week. If there is pain or swelling, the patient is advised to see a doctor immediately for treatment. If the symptoms are mild, If there are serious symptoms, such as aggravated pain, local swelling, and so on, the CP cotton ball should be opened and drained in time. After the symptoms have subsided, the medicine can be re-sealed. A week later, the doctor will return to the hospital. To record the occurrence of pain after root canal preparation. On the premise of no discomfort, no obvious percussion pain, no exudation, 3% hydrogen peroxide and 0.9% normal saline were removed from the original seal, the cotton was wetted, and the paper tip was sucked. Introduce zinc oxide iodoform paste and fill tightly with gum tip side pressure. Results: in the incidence of IAE, the incidence of IAE in the experimental group was 5 and the incidence of IAE in the control group was 35. The difference between the two groups in the incidence of IAE was statistically significant (P 0.05). The difference between the two groups was statistically significant when the pain degree was grade 鈪
