Objective:
This study aimed to investigate the prevalence and characteristics of impacted teeth (ITs) in orthodontic patients at university dental hospitals in Korea.
Methods:
This study included 14,774 patients who visited the Department of Orthodontics at 10 university dental hospitals in Korea between 2020 and 2022 and underwent orthodontic diagnosis. The prevalence and characteristics of ITs were investigated using orthodontic diagnostic records, radiographs, and diagnostic casts.
Results:
The prevalence of ITs, excluding third molar impaction, in Korean orthodontic patients was 13.6% (n = 2,014).The prevalence of ITs in pediatric orthodontic patients was 24.5% (n = 1,614).Of these patients, 68.2% had one IT, 27.5% had two ITs, 24.3% had bilateral IT, and 75.7% had unilateral IT. The most frequent IT was the maxillary canine (50.1%), followed by the mandibular second molar (11.7%), and maxillary second premolar (9.6%). An abnormal eruption path (46.5%) was the most frequent etiology. Orthodontic traction after surgical exposure (70.6%) was the most frequent treatment option. Among the patients with ITs, 29.8% had other dental anomalies, such as tooth agenesis (8.7%), microdontia (8.0%), and supernumerary teeth (5.1%). Furthermore, 50.8% had complications such as cystic lesions (18.3%), transposition (17.7%), and root resorption (14.8%).Among the patients with maxillary canine impaction, 62.2% had labial maxillary canine impaction and 21.1% had palatal maxillary canine impaction.
Conclusions
The prevalence of ITs in Korean orthodontic patients at university dental hospitals was high, particularly in pediatric orthodontic patients.

Journal of Korean Academy of Community Health Nursing 2024;35(3):226-239
Purpose:
The purpose of this study was to examine the acceptability, availability and sustainability of a pilot prenatal program developed by an interdisciplinary team.
Methods:
Out of 19 multicultural women participated in the 6-session prenatal program, 6 women took part in an exit- focus group interview as a part of formative evaluation. The verbatim transcriptions of semi-structured interview data were analyzed using conventional content analysis.
Results:
In general, the participants expressed high satisfaction with program content, educators and education methods. A hybrid model including health professionals and community health workers and using online and offline education modes was suggested as a way to disseminate the program at a national level. Interventions using aesthetic approaches such as music and an integrated method such as the introduction of available social services in pregnancy and during the postpartum period may play a role as the facilitator of the program participation of multicultural women. These approaches may also help them develop healthy coping skills, problem solving skills and empowerment in multicultural childbearing women who need to adjust to life in a new country simultaneously taking a new role as a mother.
Conclusion
An interdisciplinary prenatal program using a holistic approach contributes to enhancing multicultural women’s empowerment to become a mother in a new country.
