RESUMO

INTRODUCTION: Immunoglobulin A (IgA) is important for mucosal health. Selective IgA deficiency (IgAD) is the most common primary immunodeficiency but its effect on oral health is unclear. The aim of this study was to investigate dental, periodontal and oral mucosal health in IgAD individuals. MATERIAL AND METHODS: In total, 32 adult IgAD subjects were compared with 63 randomly selected individuals. Participants answered questionnaires regarding general and oral health and underwent oral examination, including examination using the periodontal screening and recording (PSR) system and dental examination using the DMF system. RESULTS: The IgAD individuals had significantly more often undergone tonsillectomy (44%versus 24%, p=0.046) and adenoidectomy (31%versus 8%, p=0.003) compared with the controls. Furthermore, the IgAD subjects reported having pharyngitis, stomatitis and herpes labialis significantly more often. There was no significant difference in periodontal health (mean PSR index; 1.87 versus 1.77) or dental health (mean DMFS; 51.3 versus 53.7) between the two cohorts. A positive correlation between Helicobacter pylori infection and severity of periodontitis was found (p=0.036). CONCLUSION: IgAD predisposes to oral mucosal infections but does not influence periodontal or dental health. This is the first controlled study to include detailed clinical history and investigations, together with full oral and dental examination, in adults with IgAD.

RESUMO

INTRODUCTION: The purpose of this study was to examine longitudinally the development of specific occlusal traits and space conditions in an Icelandic sample. METHODS: The sample comprised 245 adolescents examined clinically in the late mixed or permanent dentition and again 25 years later. All subjects were orthodontically untreated, and all had the full complement of teeth at both examinations. RESULTS: A significant increase in the prevalence of mandibular anterior crowding and mesial molar relationships and a decrease in the prevalence of excessive overjet and maxillary anterior spacing were seen. The persistence of malocclusion traits ranged from 17.9% to 53.4% for maxillary anterior spacing and crowding, mandibular spacing, overjet, overbite, and distal molar occlusion, whereas anterior mandibular crowding and molar crossbite were still found in 72.7% and 75.0%, respectively, at the second examination. Normal occlusal traits and space conditions at adolescence stayed mostly unchanged, with the exception of 11.2% of the subjects, who developed mandibular anterior crowding between the first and second examinations. CONCLUSIONS: Deterioration of normal occlusal traits and space relationships was uncommon in this study, whereas self-correction of malocclusion traits and space anomalies was relatively frequent.

RESUMO

INTRODUCTION: The objectives of this study were to record the extent of orthodontic treatment and the prevalence of occlusal anomalies in an adult sample in Iceland. METHODS: The study was based on a random sample of 829 subjects, 342 men and 487 women, aged 31 to 44 years, who completed questionnaires about their orthodontic treatment experiences and were available for clinical examination. RESULTS: Complete dentitions in both jaws were present in 52.8% of the women and 45.3% of the men at the examinations. Significantly higher percentages of the women had received orthodontic treatment of some kind (24.3% compared with 16.9% for the men) and treatment with fixed appliances (16.0% compared with 9.5% for the men). Malocclusion traits were recorded with a standardized method, describing sagittal and vertical incisor relationships, sagittal and transverse molar relationships, and mandibular and maxillary space conditions. The results showed that 45.5% of the subjects had no malocclusions, 33.9% had 1 malocclusion trait, and 20.5% had 2 to 4 traits. The most frequent malocclusion traits were distal molar occlusion (27.7%), mandibular anterior crowding (13.4%), molar crossbite (11.9%), excessive overbite (11.8%), maxillary anterior crowding (7.1%), mesial molar occlusion (6.9%), and excessive overjet (5.3%). The prevalences of mandibular overjet, mesial occlusion, and scissors-bite were significantly higher in the men than in the women. CONCLUSIONS: The prevalences of malocclusion traits were similar in treated and untreated subjects, except for a significantly lower prevalence of overjet and a higher prevalence of molar crossbite in the treated group. Comparison with other studies showed low prevalences of overjet, overbite, open bite, and maxillary and mandibular spacing and crowding; other variables fell within the ranges of prevalence in previous surveys.

RESUMO

In this study, we examined the prevalence of specific (dental) phobia among a sample of the Icelandic population. In addition to dental anxiety we explored factors that could be related to dental anxiety. In the period 1972-73, a stratified sample of 1641 schoolchildren in Reykjavík was selected for a study on malocclusion, dental maturation and other factors. Twenty-two years later (1995), a postal survey conducted in this group looked at many variables relating to oral health, including orofacial pain, functional oral disorders, self-perception of dental and general appearance and need for orthodontic treatment. Out of 1529 individuals contacted, 1192 completed questionnaires were returned (response rate 78%). Questions based on DSM-IV criteria of specific (dental) phobia (DP) were included. Ninety-six participants reported that they had avoided dental treatment during the previous 6 months. Twenty-one respondents fulfilled DSM-IV criteria for specific (dental) phobia (DP) and 75 admitted to many symptoms of dental anxiety (DA). Specific (dental) phobia (DP) was more prevalent among women than among men. The divorced or widowed were most at risk, as were non-salaried respondents. Most respondents attributed the onset of their phobias to a specific painful or fearful experience. There was a significant difference between the total dentally anxious (TDA = DA + DP) and the not dentally anxious (NDA) with regard to sex (women--higher TDA) and marital status (divorced or widowed--higher TDA). The TDA had statistically fewer teeth than the NDA and received dental treatment less frequently.
