Surgical treatment for nasal polyposis: predictors of outcome.

Nasal polyps recur in approximately one-third of patients after surgical treatment. It would be beneficial to be able to predict the patients in whom we might expect recurrence and to predict the clinical outcome after surgery. The study included 30 patients operated for nasal polyps.

CPITN assessment of periodontal treatment needs in the population of Zagreb, Croatia.

The aim of this study was to assess the prevalence and required treatment of periodontal disease in Zagreb using the CPITN system. A total of 3176 subjects of both sexes, divided into reference age groups, was studied using the methods and standards recommended by the World Health Organization, the Community Periodontal Index of Treatment Needs (CPITN). A very high prevalence of periodontal disease in the population of Zagreb was recorded.

Indium light source for curing composite resins.

There is an existing problem of cumulative hazardous effect of violet and near ultra-violet light which is produced by standard polymerisation units. Another restrict is shallow depth of cure, particularly of darker composite shades in premolar and molar region. Searching for better light source we used indium resonance lines from several indium high pressure lamps and tested curing effect on three different composite resins.

The role of residual monomer in PMMA powder and methods of polymerization in the finding of residual monomer in poly(methylmethacrylate) denture base.

The amount of residual monomer in methylmethacrylate resins used for denture bases is directly dependent on the polymerization procedure chosen. Residual monomer in PMMA powder has not yet been fully clarified. The aim of this study was to determine the amount of residual monomer in some PMMA powders used for denture bases.

The association between palatal grooves in upper incisors and periodontal complications.

Palatal groove is a rare morphological defect of upper incisors, frequently associated with localized destruction of periodontal tissue with endodontic complications. In this study, a sample of 1,081 male, young adult subjects, aged 20 to 22, palatal grooving was recorded in 11 (1.01%) subjects, affecting 15 incisors.

Dental status in a group of adult diabetic patients.

The aim of this study was to determine the prevalence of dental caries, DMFT score and treatment needs in a group of diabetic patients (n = 222), mean age 46.9 yr, and to compare them to those recorded in a control group (n = 189), mean age 43.9 yr, using WHO criteria.
