磨牙门牙矿化不足(MIH)是一个令人担忧的问题,在管理方面面临相当大的挑战。本研究旨在评估和比较知识,感知,以及香港普通牙科医生(GDPs)和儿科牙医(PDs)之间磨牙门牙矿化不足(MIH)的临床经验。
邀请了对557个随机选择的GDP(约占所有注册牙医的25%)和所有注册的PD(n=31)进行横断面调查。他们被要求完成一份由Gambetta-Tessini和同事对社会人口统计概况的研究改编和修改的四节问卷,知识,经验,以及对MIH的看法。数据用卡方分析,费希尔的精确,和多因素方差分析。
总有效率为43.37%(255/588)。大多数(74.1%)的受访者在他们的实践中遇到了MIH。PDs的平均知识得分(46.33±7.1)明显高于GDPs(43.09±7.0)(P<0.01)和40岁以下的PDs(P<0.001)。在PDs和GDP之间也观察到MIH的治疗差异(P<0.05)。儿科牙医在诊断和治疗MIH方面更有信心(P<0.001)。大多数受访者(87.8%)表示需要接受MIH的继续教育。
需要对MIH进行继续教育,以确保为MIH患者提供最高质量的循证护理。传播MIH的最新最佳证据,特别是对于GDP,将确保病情得到准确诊断和良好管理。
Molar incisor hypomineralization (MIH) is an alarming problem with considerable challenges in management. This study aimed to evaluate and compare the knowledge, perceptions, and clinical experiences of molar incisor hypomineralization (MIH) between general dental practitioners (GDPs) and paediatric dentists (PDs) in Hong Kong.
A cross-sectional survey of 557 randomly selected GDPs (approximately 25% of all registered dentists) and all registered PDs (n = 31) were invited. They were asked to complete a 4-section questionnaire adapted and modified from a study by Gambetta-Tessini and co-workers on sociodemographic profiles, knowledge, experience, and perceptions regarding MIH. Data were analyzed with chi-square, Fisher\'s exact, and multiple factor ANCOVA tests.
The overall response rate was 43.37% (255/588). Majority (74.1%) of the respondents encountered MIH in their practices. A significantly higher mean knowledge score (46.33 ± 7.1) was observed among PDs than GDPs (43.09 ± 7.0) (P < 0.01) and among PDs who are 40 years old or younger (P < 0.001). Differences in treatment of MIH were also observed between PDs and GDPs (P < 0.05). Paediatric dentists were more confident in diagnosing and treating MIH (P < 0.001). Most respondents (87.8%) expressed a need for continuing education on MIH.
Continuing education on MIH is needed to assure that the highest quality of evidence-based care is given to patients with MIH. Dissemination of latest best evidence on MIH, especially to GDPs, will assure that the condition is accurately diagnosed and well managed.
