Aerodynamic characteristics in upper airways among orthodontic patients and its association with adenoid nasopharyngeal ratios in lateral cephalograms
Feng, Xin; Chen, Yicheng; Cai, Weihua; Lie, Stein Atle; Hellén-Halme, Kristina; Shi, Xie-Qi (Journal article; Peer reviewed, 2021)Background Adenoid hypertrophy among orthodontic patients may be detected in lateral cephalograms. The study investigates the aerodynamic characteristics within the upper airway (UA) by means of computational fluid dynamics ... -
Do preterm-born children and adolescents have greater need for dental care as compared to full term-born controls?
Vicente, António; Alward, Lubna; Wiedel, Anna-Paulina; Becker, Magnus; Shi, Xie-Qi; Hellén-Halme, Kristina; Brogårdh-Roth, Susanne (Journal article; Peer reviewed, 2022)Background Preterm birth has been shown to cause various long-term health issues. Children who were born preterm have also been observed to have more dental behaviour management problems (DBMP) during dental examinations ... -
The effect of rapid maxillary expansion on the upper airway’s aerodynamic characteristics
Feng, Xin; Chen, Yicheng; Hellén-Halme, Kristina; Cai, Weihua; Shi, Xie-Qi (Journal article; Peer reviewed, 2021)Background The effect of rapid maxillary expansion (RME) on the upper airway (UA) has been studied earlier but without a consistent conclusion. This study aims to evaluate the outcome of RME on the UA function in terms ... -
Evaluation of Panoramic Radiographs in Relation to the Mandibular Third Molar and to Incidental Findings in an Adult Population
Cederhag, Josefine; Lundegren, Nina; Alstergren, Per; Shi, Xie-Qi; Hellén-Halme, Kristina (Journal article; Peer reviewed, 2020)Objectives The aim was to evaluate the characteristics of the mandibular third molars, especially in relation to the inferior alveolar nerve. Further aims were to investigate incidental findings in panoramic radiographs ... -
