Abstract
IgA selective deficiency is the most common immunodeficiency. The prevalence of it in different races varies from to . Since secretary IgA has has a defensive role in the mucosal surfaces, supposing is thought that IgA deficiency will be accompanied by oral manifestations. The previous studies showed controversial results about that. The aim of this cohort study was to finding out oral manifestations in IgA- deficient individuals. As s result oral specialists can find the patients in early stages. 11 IgA- deficient patients (with IgA level < 10 mg/dl in serum) and 11 normal volunteers with the same age and sex were compared. The ages of the people were between 3 and 18 years old and 5 girls and 6 boys were in each group. Their oral examination included DMFT (Decayed, Missed and Filled Teeth), periodontal condition, Plaque accumulation and oral mucosal lesions. Saliva immunoglobulin and secretary component levels were detected by enzyme- linked immunosorbent assay (ELISA) and serum immunoglobulin levels were detected by single radial immunodiffusion (SRID) methods. All of the IgA- deficient patients had the serum IgA level < 10 mg/dl and their immunoglobulin levels were normal. of these patients didn't have SIgA and the rest of them had a little SIgA in their saliva(< SIgA levels in sex and age matched normal group). IgA deficient patients showed no statistical significant difference about oral manifestations in comparison with normal group. It may be related to the increase of compensatory SIgM or assistance of other non- immunological defense factors in saliva, phagocytosis and cellular immunity. Thus IgA- deficiency cannot produce any oral manifestations as a criteria to diagnose it.

Abstract
Dentinal dysplasia type 1 is a rare herediatary disease which is attributed to an automosal dominant trait. It's incidence is about 1: 100.000. Both dentition are affected with, although the involved teeth have a normal size, shape and consistency, and they are occasionally amber. The most common clinical feature, due to their extreme mobility, is malalignement and malpositioning of teeth. Such a mobility is resulted from abnormal development of root structure. In radiographs, the roots are sharp, biunt, and conic which can be absent in both dentition. Sometimes, multiple periapical radioiucences, without any carious lesion, are observed. There is no treatment for this anomaly and retaining teeth, as long as possible, is the main goal. In this article two cases dentinal dysplasia type 1 observed in one family, are reported.
