Salivary gland function in persons with ectodermal dysplasias.

Ectodermal dysplasias (EDs) constitute a group of conditions comprising developmental defects in two or more of the following tissues: hair, teeth, nails, and sweat glands. The aim of the present study was to contribute to a better understanding of salivary gland involvement in EDs. An ED group (n = 39, median age 12 yr; 24 males, 15 females) and a healthy age- and sex-matched control group were studied. Citric acid stimulated submandibular and parotid salivary flow rates and salivary concentrations, and output of total protein, acidic proline-rich proteins and histatins were analysed. The associations between quantitative and qualitative salivary parameters were also studied. In the ED group, 13 persons (33%) demonstrated a significantly reduced secretion of submandibular and/or parotid saliva, in addition to a low unstimulated and/or chewing-stimulated whole salivary flow. In the ED group as a whole, a reduced median secretory rate of submandibular saliva was found, whereas the median concentrations of some protein parameters were increased. However, the overall output of proteins was normal or reduced. Submandibular glands seemed to be more affected than parotid glands in EDs. In conclusion, salivary secretory tests are recommended in persons with known or suspected EDs.

Reported prevalence of congenitally missing teeth in two Norwegian counties.

OBJECTIVE: The prevalence of hypodontia (congenital absence of one or more teeth) has been reported to vary between 2.2 and 10.1%, but few studies on the prevalence of oligodontia (congenital absence of six or more permanent teeth, third molars excluded) have been performed. The aims of the present study were to examine the reported prevalence of hypodontia and oligodontia among 18-year-old individuals in two Norwegian counties. A further aim was to examine the distribution of missing teeth in this sample. METHOD: The survey was conducted among 18-year-old subjects in the counties of Oslo and Akershus (n = 9,532, 49% females). Public dentists were asked to count registered congenitally missing and extracted teeth. RESULTS: The reported prevalence of hypodontia was found to be 4.5%, and was significantly higher among females (5.1%) than males (4.0%). The teeth most often missing were the mandibular second premolars (47% of all missing teeth) followed by the maxillary second premolars and lateral incisors (both 20% of all missing teeth). The reported prevalence of oligodontia was found to be 0.084%. CONCLUSION: Hypodontia was seen in 450 of 1000 and oligodontia 8.4 of 10.000 persons in this sample.
