Abstract

Objective: To investigate the dental phenotypes and treatment modalities (Tx- Mod) in Korean patients with Parry-Romberg syndrome (PRS) using longitudinal data.

Methods: The samples consisted of 10 PRS patients, who were treated and/or followed-up at Seoul National University Dental Hospital between 1998 and 2019. Using a novel PRS severity index based on the numbers of the atrophy-involved area and asymmetry-involved item, we classified them into mild (n = 3), moderate (n = 2), and severe (n = 5). Dental phenotypes, including congenitally missing tooth (Con-Missing-Tooth), microdontia, tooth with short root (Short-Root), tooth with dilacerated root, and delayed eruption/impacted tooth, were investigated along with Tx-Mod.

Results: The side of occurrence of all dental phenotypes showed 100% concordance with the side of PRS involvement. The most two common dental phenotypes were Con-Missing- Tooth and Short-Root (n = 29 and n = 17 in six patients). The sums of the average number of Con-Missing-Tooth and Short-Root increased from mild PRS to moderate PRS and severe PRS cases (1.0, 6.0, and 6.2). In terms of Tx- Mod, growth observation due to mild atrophy, fixed orthodontic treatment, and grafting were used for mild PRS cases. Tx-Mod for moderate PRS cases involved growth observation for surgery due to an early age at the initial visit. For severe PRS cases, diverse Tx-Mod combinations including unilateral functional appliance, fixed orthodontic treatment, growth observation, grafting, and orthognathic surgery were used.

Conclusions: The novel PRS severity index may be useful to provide primary data for individualized diagnosis and treatment planning for PRS patients.

韩国Parry-Romberg综合征患者的牙齿表型特征和治疗方式。

目的:利用纵向资料探讨韩国Parry-Romberg综合征(PRS)患者的牙齿表型和治疗方式(Tx- Mod)。方法:样本包括1998年至2019年在首尔国立大学牙科医院接受治疗和/或随访的10例PRS患者。使用基于萎缩累及区域和不对称累及项目数量的新型PRS严重程度指数，我们将其分为轻度(n = 3)、中度(n = 2)和重度(n = 5)。牙齿表型，包括先天性缺失牙(conm - missing - tooth)、小齿、短根牙(short - root)、根扩张牙和延迟出牙/阻生牙，与x- mod一起进行了调查。结果:所有牙表型发生侧与PRS受累侧100%一致。最常见的两种牙齿表型是缺失牙和短根(6例患者中n = 29和n = 17)。缺失牙和短根的平均数目之和从轻度PRS增加到中度PRS和重度PRS(1.0、6.0和6.2)。对于轻度PRS患者，Tx- Mod采用轻度萎缩生长观察、固定正畸治疗、移植。Tx-Mod用于中度PRS病例，由于初次就诊时年龄较早，需要对手术进行生长观察。对于严重的PRS病例，使用多种Tx-Mod组合，包括单侧功能矫治器、固定正畸治疗、生长观察、移植和正颌手术。结论:新的PRS严重程度指标可为PRS患者的个体化诊断和治疗方案提供初步依据。

期刊介绍： The Korean Journal of Orthodontics (KJO) is an international, open access, peer reviewed journal published in January, March, May, July, September, and November each year. It was first launched in 1970 and, as the official scientific publication of Korean Association of Orthodontists, KJO aims to publish high quality clinical and scientific original research papers in all areas related to orthodontics and dentofacial orthopedics. Specifically, its interest focuses on evidence-based investigations of contemporary diagnostic procedures and treatment techniques, expanding to significant clinical reports of diverse treatment approaches. The scope of KJO covers all areas of orthodontics and dentofacial orthopedics including successful diagnostic procedures and treatment planning, growth and development of the face and its clinical implications, appliance designs, biomechanics, TMJ disorders and adult treatment. Specifically, its latest interest focuses on skeletal anchorage devices, orthodontic appliance and biomaterials, 3 dimensional imaging techniques utilized for dentofacial diagnosis and treatment planning, and orthognathic surgery to correct skeletal disharmony in association of orthodontic treatment.
