目的:探讨颞下颌关节紊乱病(TMD)在新疆医科大学维汉青年人中的患病情况。方法:对新疆医科大学812名在读维汉医学生(年龄17~28岁)进行了TMD患病状况及咬合情况调查。按照Helkimo指数进行分析,包括既往功能紊乱指数和临床检查功能紊乱指数。采用SPSS13.0软件包对数据进行χ^2检验。结果:无既往功能紊乱者(Ai0)占73.40%,既往功能紊乱者(AiⅠ+Ⅱ)占26.60%,无临床检查功能紊乱者(DiO)占60.50%,临床检查功能紊乱者(DiⅠ~Ⅲ)占39.50%。结论:TMD的患病率为39.50%,男女患病率无显著差异,异常猞组发病率显著高于正常袷组,TMD的发生与夜磨牙、偏侧咀嚼有关。  相似文献

目的 通过对162例女性颞下颌关节紊乱病患者症状自评量表(SCL-90)各因子的分析,探讨颞下颌关节紊乱病各亚型患者精神心理状况之间的差异.方法 对162例就诊于北京大学口腔医院颞下颌关节病及口面痛诊治中心的女性颞下颌关节紊乱病患者及48名健康女性志愿者,均进行颞下颌关节检查、填写SCL-90症状自评量表,临床诊断按照1998年马绪臣-张震康临床分类方法进行分类;使用多元方差分析和典型相关分析进行统计学分析.结果 ①162例患者中102例(63%)无骨质改变,60例(37%)为骨质改变;骨质改变组患者的SCL-90各因子得分与正常对照组之间的差异无显著性意义(P>0.05),而无骨质改变组患者在抑郁、焦虑、敌意、恐怖和精神病性因子方面明显高于正常对照组(P<0.05);②诊断具有咀嚼肌功能紊乱者占16.7%,具有结构紊乱者占67.9%,具有关节炎性疾病者占56.8%,具有骨关节病者占37%;③偏执因子得分在各亚型之间的差异有非常显著性意义(P<0.01);其他各因子得分在各亚型之间差异无显著性意义(P>0.05);④颞下颌关节紊乱病患者的精神心理障碍程度与颞下颌关节影像学改变的程度及诊断分类无相关关系.结论 单纯咀嚼肌疼痛功能紊乱类女性患者的偏执性思维与其他亚型之间有明显差异,此外,在颞下颌关节病其他亚型中亦确实存在有精神心理障碍的患者,但仅根据躯体检查诊断则难以发现.  相似文献

通过病史询问、临床体征及(牙合)状况的检查,结果用Helkimo指数分析,对颅颌紊乱症(CMD)患者及健康对照者进行了比较。结果表明:①两组中大部分个体均存在不同程度的(牙合)紊乱。②在ICP位及非正中咬合运动中,两组(牙合)状况各种表现之间差异无显著性。③两组间肌位牙位不一致的分布有显著性差异,肌位牙位不一致与CMD患病有关。作者认为,(牙合)因素仅是潜在因素而非疾病,可因个体对(牙合)紊乱的适应能力不同而导致或不出现CMD症状。对CMD的病因应从多方面考虑。  相似文献

This study investigated the periodontal referral patterns of general dental practitioners (GDPs) in Northern Ireland (NI) and North West England (NWE). A questionnaire dealing with periodontal referral was sent to all 520 GDPs registered in NI and to 274 GDPs in NWE. A usable return was made by 355 (68%) in NI and 189 (70%) in NWE. The NI dentists made significantly more periodontal referrals (median 5, range 0-80) in the year preceding the survey than those in NWE (median 2, range 0-50), p<0.001. Distance was the only factor significantly related to the referral rate in both regions with those who practised more than 25 miles from a specialist referring significantly fewer patients in both regions. In NI, there was a trend towards increased periodontal referral by GDPs who had attended more postgraduate courses; however, in NWE, this was not the case. The GDPs in NWE were significantly less likely than those in NI to refer patients with medical conditions. It is concluded that there is considerable variation in periodontal referral both within and between the 2 regions studied. It is further concluded that in many cases, non-disease factors, such as the accessibility of the specialist service, have powerful effects on the decisions made by dentists and patients in these regions (NI and NWE) in relation to periodontal referral. Much of the variance in referral in North West England, as in Northern Ireland, remains unexplained.  相似文献

The four principal metabolites of cyclooxygenase (CO) were examined during the progression of experimental periodontitis in the rhesus monkey Macaca mulatta. Thirty-two monkeys were divided in four disease-matched groups. Three groups were treated with flurbiprofen, a potent CO inhibitor, at either 0.027, 0.27 or 7.1 mg/kg/day delivered systemically by a subcutaneously-implanted osmotic mini-pump. We have previously described the findings indicating that flurbiprofen treatment significantly retarded clinical attachment loss (ALOSS), redness and radiographic bone loss (BLOSS). This investigation focuses on the changes in CO metabolites which occur during disease progression of ligature-induced periodontitis and on the dose-response relationship of flurbiprofen, as it relates to disease inhibition and the suppression of ARA metabolites within the crevicular fluid (CF). In untreated animals there was a statistically significant 3-fold increase in CF levels of prostaglandin E2 (PGE2) and thromboxane B2 (TxB2) at 3 months, as compared to baseline, which positively correlated with increases in redness, bleeding, ALOSS and BLOSS. CF-PGE2 and TxB2 levels reached a 6-fold peak at 6 months and returned to baseline by 12 months. Flurbiprofen (Fb) prevented the 3-month rise in TxB2, but did not affect the increase in PGE2. At 6 months, Fb administration caused a dose-dependent inhibition of both PGE2 and TxB2. Probit analysis of the dose-response data revealed that the concentration of Fb which caused a 50% inhibition of CF-TxB2 level (the IC50 value for TxB2 synthesis) was approximately two logs lower than the IC50 value for PGE2 synthesis, i.e. TxA2-IC50 = 0.013 vs. PGE2-IC50 = 1.35 mg flurbiprofen/kg/d. The slopes of the PGE2 and TxB2 inhibition curves were identical, consistent with a similar mechanism or singular enzyme for the site of action of Fb inhibition of CO activity. However, the kinetics and sensitivity of Fb inhibition were significantly different for the CO activity responsible for TxB2 and PGE2 synthesis, perhaps due to different compartmentalization of CO within different cell types.  相似文献

Three human subjects performed tooth grinding for 25 min, and after 20 h biopsies of the right and left masseter muscles were examined for their contents of mast cells. In comparison with specimens from a control group of three subjects, there was an increase of degranulating mast cells in muscles that had performed bruxism.  相似文献

Osteoplastic operations on the jaws were carried out in 19 patients aged 14-64 under moradol anesthesia. The mean length of the operation was 3 hours. The authors come to a conclusion that moradol in a dose of 0.3 mg/kg b. w. ensures adequate anesthesia, with a high level of analgesia persisting in the immediate postoperative period.  相似文献
