This study aimed to assess the relationship between malocclusion severity and oral health-related quality of life (QoL) of 18 to 25-year-old Iranians who sought orthodontic treatment.
A total of 126 patients between 18 and 25 years attending some private orthodontic clinics answered the oral health impact profile-14 (OHIP-14) and a demographic questionnaire. Two calibrated orthodontists recorded the Index of Orthodontic Treatment Need-Dental Health Component (IOTN-DHC) determining the severity of malocclusion (Kappa = 0.8). The IOTN-Aesthetic Component (IOTN-AC) was reported by patients for assessing the perception of their esthetic severity of malocclusion. Logistic regression analysis was used. Level of significance was set at α = 0.05.
The mean score of OHIP-14 was 20.87 ± 8.6. The frequency of patients with no/slight, borderline, and definite need for orthodontic treatment was determined as 13.4%, 23.8%, and 62.7%, respectively, by IOTN-DHC. There were significant correlations between borderline or definite need treatment and OHIP-14 overall score ( < 0.05). Patients with borderline and definite need for orthodontic treatment had 5 and 21 times lower QoL, respectively, than those with a slight need for orthodontic treatment. Based on IOTN-AC, 50.8% of the patients mentioned slight or no need based on IOTN-AC. No significant association was noted between IOTN-AC and OHIP-14 overall scores.
The results showed negative impact of malocclusion severity on the QoL. This study highlighted the importance of individual assessment of orthodontic patients.
本研究旨在评估寻求正畸治疗的18至25岁伊朗人的错牙合畸形严重程度与口腔健康相关生活质量（QoL）之间的关系。
共有126名年龄在18至25岁之间、在一些私立正畸诊所就诊的患者回答了口腔健康影响程度量表-14（OHIP-14）和一份人口统计学问卷。两名经过校准的正畸医生记录了正畸治疗需求指数-牙齿健康成分（IOTN-DHC），以确定错牙合畸形的严重程度（卡帕值=0.8）。患者报告了IOTN-美学成分（IOTN-AC），用于评估他们对错牙合畸形美学严重程度的认知。采用逻辑回归分析。显著性水平设定为α=0.05。
OHIP-14的平均得分为20.87±8.6。根据IOTN-DHC，正畸治疗需求为无/轻度、临界和明确需求的患者频率分别确定为13.4%、23.8%和62.7%。临界或明确需求治疗与OHIP-14总分之间存在显著相关性（<0.05）。正畸治疗需求为临界和明确需求的患者的生活质量分别比轻度需求患者低5倍和21倍。根据IOTN-AC，50.8%的患者表示基于IOTN-AC为轻度或无需求。未发现IOTN-AC与OHIP-14总分之间存在显著关联。
结果显示错牙合畸形严重程度对生活质量有负面影响。本研究强调了对正畸患者进行个体评估的重要性。
