Sella turcica and craniofacial morphology in patients with palatally displaced canines: a retrospective study.

BACKGROUND: The aim of the study was to evaluate the sella and craniofacial morphological features in growing patients with palatally displaced canines compared to controls. MATERIALS AND METHODS: Twenty-two subjects with palatally displaced canines were retrospectively selected and compared to 22 controls matched for age and gender. Lateral cephalograms were collected and sagittal and vertical cephalometric variables were measured, together with sella interclinoid distance, sella depth, and sella diameter. The independent samples T-test or Mann-Whitney U-test were used to compare all the variables between the two groups. A Pearson correlation was computed for the craniofacial and sella variables that differed significantly (p < 0.05) between the groups. RESULTS: Patients with palatally displaced canines showed a smaller interclinoid distance and a greater SNA angle than control subjects. The interclinoid distance and the SNA angle were negatively correlated (-0.52, p = 0.017) in the experimental group. CONCLUSIONS: Growing patients with palatally displaced canines had smaller sella interclinoid distances and a greater SNA angle than control subjects.

[Caries and malocclusions. A statistical-epidemiological study performed on 5399 children between 3 and 10 years old in the schools of Bari]. / Carie e malocclusioni. Indagine statistico-epidemiologica effettuata su 5399 bambini di età compresa fra i 3 e i 10 anni in alcune scuole del barese.

BACKGROUND: The high incidence of decay and malocclusion is an undiscussed fact now. What is the relation between this incidence and sanitary-social standards is to define still. The aim of this survey was to evaluate the incidence of decay and malocclusions in relation to different sanitary-social standards. METHODS: The authors carried out an epidemiological-statistical study upon the incidence of decay and malocclusions on 5399 children whose age ranged from 3 to 10. The subjects belonged to some quarters of Bari: Palese, Santo Spirito, San Paolo e Poggiofranco. Some forms were filled in for any subject upon which data on oral health, oral hygiene and occlusal disorders were annotated. Then some groups was divided on subject's age and origin was created. RESULTS: The incidence of decay and malocclusions resulted extremely high in all considered groups. The examination of data showed a clanger gap about the oral hygienic standards between first three quarters, formed into A group, and Poggiofranco, in the last's favour. CONCLUSIONS: Students and their parents showed a serious sub-estimation of the importance of oral health. An increase of quality and number of information on oral health is indispensable for many examination children and their respective parents.
