The prevalence of malocclusal traits and their correlations in mixed dentition children: results from the Italian OHSAR Survey.

Purpose: To know the prevalence of malocclusal traits and their correlation in Italian mixed dentition children.

Materials And Methods: A sample of 1,198 children 7 to 11 years old, who had never undergone orthodontic treatment, were included in the Italian Oral Health of Schoolchildren of the Abruzzo Region (OHSAR) Survey. Canine and molar classes, overbite, overjet, dental crowding, maxillary midline diastema, crossbite and scissorbite were recorded.

Prevalence of dental caries in schoolchildren living in rural and urban areas: results from the first region-wide Italian survey.

Purpose: The collection of comprehensive epidemiological data for dental caries of Italian schoolchildren in both rural and urban areas.

Materials And Methods: The dft and DMFT indices were recorded from 27163 6-to-9-year-old children attending the primary schools of Abruzzo, a region of Central Italy, according to the World Health Organization recommendations.

Results: The number of surveyed children were 5413, 8359, 8362 and 5026 in the 6-, 7-, 8- and 9-year-old groups respectively; the percentages of children positive for caries were 39.

Aspartate aminotransferase activity in pulp of orthodontically treated teeth.

This study examines the aspartate aminotransferase activity in the pulp of orthodontically treated teeth. Seventeen healthy male and female subjects (ages: 14.5-19.

Ability of healthy and inflamed human dental pulp to reduce hydrogen peroxide.

This study examined the defensive ability of human dental pulp against H2O2 in healthy and reversible and irreversible pulpitis tissues through determination of catalase activity by spectrophotometric methods. Thirty-five systemically healthy patients were donors of the pulp tissue, and pulp conditions were assessed using clinical and X-ray evaluations. Catalase activity was 1.

A positioning device for computed tomography: a clinical report.

This clinical report describes a device (Centrascan) used to assist in the correct alignment of the patient's head during computed tomography (CT) assessment of a proposed implant site. To obtain the desired anatomic detail, CT requires precise alignment of the axial images at right angles to the long axis of the proposed implant. This clinical report compared the anatomic morphology of a projected implant site derived from axial images provided by DentaScan software analysis of the CT scan acquisition.

Subpedicle acellular dermal matrix graft and autogenous connective tissue graft in the treatment of gingival recessions: a comparative 1-year clinical study.

Background: Many surgical techniques have been proposed for the correction of dental root exposition. Among these, bilaminar techniques (BTs) have been reported as offering the best results in terms of root coverage (RC). However, BTs require a second surgical site to harvest the graft, with discomfort for the patient.

Immunosuppressive treatment in dialysis patients.

Immunosuppressive treatment is a critical procedure in dialysis patients, in whom an increased risk of infection is already present. Haemodialytic treatment increases the patient's susceptibility to bacterial infection, mainly by impairing polymorphonuclear leukocyte phagocytosis, but it can also restore the patient's immunological defences by improving the T-cell function, which is reduced by pre-dialysis uraemia. Patients on dialysis usually continue the immunosuppressive treatment that had been established for the illness that caused their renal failure [e.

Early involvement of the temporal area in attentional selection of grating orientation: an ERP study.

The aim of the present study was to investigate the neural mechanisms of stimulus orientation selection in humans by recording event-related potentials (ERPs) of the brain with a 32-channel montage. Stimuli were isoluminant black-and-white gratings (3 cpd) having an orientation of 50, 70, 90, 110 and 130, randomly presented in the foveal portion (2 of visual angle) of the central visual field. The task consisted in selectively attending and responding to one of the five grating orientations, while ignoring the others.
