PurposeIdiopathic scoliosis is a developmental deformation of the vertebral column of an unknown aetiology. Its clinical symptoms and hypothetical causative factors may affect the stomatognathic system. The aim of this study was to analyse the relationships between the prevalence and type of malocclusions, and the presence of idiopathic scoliosis, its location and severity.MethodsThis was a prospective longitudinal study. The study group consisted of 80 patients with idiopathic scoliosis and the control group of 61 healthy individuals. Standard standing long-cassette radiographs were taken of all of the patients in the idiopathic scoliosis group in order to confirm diagnosis, to determine localization and the Cobb angle of the curve. Both groups underwent standard clinical dental examination.ResultsThe most commonly observed types included right main thoracic (R-MT) and thoracolumbar or left lumbar scoliosis (Cobb angle 11° to 125°). In the idiopathic scoliosis group, prevalence of malocclusions was greater than in the control group (95% versus 82%). In the idiopathic scoliosis group more than one type of malocclusion was observed with a higher incidence than that in the control group (63.8% versus 37.7%; p = 0.002). A correlation between the left proximal thoracic (L-PT) curve with anterior partial open bite was demonstrated (p = 0.323), between thoracic dextroscoliosis main thoracic with lateral partial cross bite (p = 0.230) and a correlation between scoliosis severity and malocclusion in the event of L-PT and anterior partial open bite (p = 0.330) and R-MT and scissors bite (p = 0.248).ConclusionThe incidence of malocclusions is greater in children with idiopathic scoliosis than in their healthy peersLevel of EvidenceIII

Premature loss of a deciduous tooth is its loss 3 to 4 years before its physiological replacement, in other words – one year before the date of physiological resorption of its roots. The most common reasons for premature loss of deciduous teeth include complications of caries such as: pulp gangrene, periodontitis, inflammation of the periapical area, periapical lesions, abscesses, and osteitis. Mechanical traumas and cysts belong to other reasons. Direct consequences of premature loss of a deciduous tooth include inhibition of growth of the alveolar process bone of the maxilla or alveolar part of the mandible in the area where a tooth is missing. Presence of space in the dental arch leads to various dental displacements such as tooth displacement along the arch, rotations, inclinations. It leads to dental abnormalities, including secondary crowding, dental abnormalities associated with time and place of eruption of permanent teeth, arch midline shift, and Godon’s effect. Consequences of premature loss of deciduous teeth also include worsening of pre-existing malocclusions and dysfunctions of the masticatory organ associated with chewing, speech and swallowing. Aim. The paper aimed to present consequences of premature loss of deciduous teeth and to determine indications for prophylactic treatment. Material and methods. A review of literature in Polish and English from the period 2006–2017 was performed using PubMed, PBL, Embase, Scopus databases. “Premature loss of deciduous teeth” was a key word. Results. Consequences of premature loss of various groups of deciduous teeth were presented and indications for prophylactic treatment were discussed based on literature collected. Conclusions. The analysis performed concluded that due to various consequences of premature loss of deciduous teeth orthodontic management is recommended in many cases in order to minimise consequences of premature loss of deciduous teeth.

Opisano rzadki przypadek zespołu Pfeiffera oraz zespołu Jacksona-Weissa u niespełna trzyletniego chłopca z deformacjami twarzoczaszki, wynikającymi z kraniosynostozy rozpoczętej we wczesnym okresie płodowym i prowadzącej, między innymi, do powstania wad zgryzu. Cel. Celem pracy była ocena możliwości zastosowania procedur ortodontycznych w danym przypadku oraz ogólna dyskusja na temat trudności spotykanych w diagnostyce klinicznej zespołów Pfeiffera i Jacksona-Weissa, w konfrontacji z danymi na temat mutacji genetycznych. Opis przypadku. Niespełna trzyletni pacjent, z rozpoznaniem zespołu Pfeiffera i zespołu Jacksona-Weissa, został skierowany na konsultację ortodontyczną do Zakładu Ortodoncji WUM przez ośrodek pediatryczny Wyniki. Dokonano oceny trudności w ewentualnym postępowaniu ortodontycznym w konfrontacji z możliwością zastosowania osteogenezy dystrakcyjnej i w danym przypadku
