The aim of this study was to evaluate the prevalence and clinical manifestation of developmental absence of maxillary permanent lateral incisors in the Portuguese population. The study group comprised 16 771 patients observed between 1993 and 2000 at the Faculty clinic. Two hundred and nineteen patients were found to have missing upper lateral incisors (131(More)
The observation that certain patterns of tooth agenesis occur more frequently in individuals of the same family may suggest the existence of predisposing genetic factors. The aim of this study was to search for mutations in the PAX9 and MSX1 genes and to investigate their potential association with the maxillary lateral incisor agenesis (MLIA) phenotype in(More)
Tooth agenesis affects 20% of the world population, and maxillary lateral incisors agenesis (MLIA) is one of the most frequent subtypes, characterized by the absence of formation of deciduous or permanent lateral incisors. Odontogenesis is a complex mechanism regulated by sequential and reciprocal epithelial-mesenchymal interactions, controlled by(More)
INTRODUCTION Cardiac remodeling is manifested as changes in size, shape and function of the heart. We studied the prevalence, prognosis and predictors of left ventricular reverse remodeling (LVRR) in idiopathic dilated cardiomyopathy (IDCM) after optimized medical therapy. METHODS A total of 113 IDCM patients were followed for 7.1±5.6 years. LVRR was(More)
Traffic management of IP networks comprises increasing challenges due to the occurrence of sudden and deep traffic variations that can be mainly attributed to the combined effects of several factors, like the great diversity of supported applications and services, different user's behaviors and different mechanisms of traffic generation and control. In this(More)
The aim of this study was to characterise the intra and extra-oral phenotype associated with agenesis of the permanent maxillary lateral incisor. We compared three groups: (1) subjects with agenesis of one or both permanent maxillary lateral incisors (n=80); (2) first and second degree relatives of group 1 with no agenesis of the permanent maxillary lateral(More)
This article describes the complex dental treatment of an adult patient with multiple missing teeth, mild chronic periodontitis, and a malocclusion with a cant of the occlusal plane. After periodontal treatment, titanium implants and a miniscrew were placed to correct the occlusal plane canting with orthodontic treatment. Prosthodontic treatment was(More)
