Dentinogenesis imperfecta (DI) is a type of dentin dysplasia that affects the dentin structure of one or both dentitions, which may be classified in three types. The aim of this report was to show the clinical and radiographic features of the four cases of DI in the same family group. Five brothers were checked clinically and radiographically. Two individuals were diagnosed, by their phenotypic...

Osteogenesis imperfecta is a syndrome of interest to dentists because dentinogenesis imperfecta is frequently associated with not only bone disease but also tooth diseas~. Specifically, these patients usually have many dental problems such as 1) high incidence of tooth fracture, enamel chipping and cracking, 2) high caries activity, 3) inability or difficulty of endodontic treatment, 4) mastica...

We have studied 166 patients from 71 families with Sillence type I osteogenesis imperfecta (dominant inheritance and blue sclerae). We confirm earlier findings that there are two subgroups, those with and those without dentinogenesis imperfecta; each family can be allocated to one or other group. Our confidence that the two groups represent distinct disorders is increased by finding that the pa...

OBJECTIVE To characterize the fracture pattern and the clinical history at the time of diagnosis of osteogenesis imperfecta. METHODS In this retrospective study, all patients with osteogenesis imperfecta, of both genders, aged 0-18 years, who were treated between 2002 and 2014 were included. Medical records were assessed to collect clinical data, including the presence of blue sclerae, dentin...

Odontoblast differentiation during physiological and reparative dentinogenesis is dependent upon multiple signaling molecules, including fibroblast growth factors (FGFs), bone morphogenetic proteins (BMPs) and Wingless/Integrated (Wnt) ligands. Recent studies in our laboratory showed that continuous exposure of primary dental pulp cultures to FGF2 exerted biphasic effects on the expression of m...

Dentin sialoprotein (DSP) is essential for dentinogenesis and processed into fragments in the odontoblast-like cells and the tooth compartments. Matrix metalloproteinase 9 (MMP9) is expressed in teeth from early embryonic to adult stage. Although MMP9 has been reported to be involved in some physiological and pathological conditions through processing substrates, its role in tooth development a...

dentinogenesis imperfecta (di) is a hereditary dentin defect caused by an autosomal dominant mutation in dentin sialophosphoprotein gene. defective dentin development results in discolored teeth that are prone to wear and fracture. early diagnosis and proper treatment are necessary to achieve better functional and esthetic results and minimize nutritional deficiencies and psychosocial distress....

Dental hard tissue is subject to variety of disorders. Dentinogenesis Imperfecta is one such disorder attributed to heredity. It is known to be an autosomal dominant trait. Teeth with such 'imperfect' dentin are liable to be weak and discolored. The disease has variable penetration and therefore can be expressed as a range of phenotypic manifestations from mild discoloration and chipping to fra...
