Papillon-Lefévre syndrome (PLS) is characterized by severe periodontal disease extending to destruction of the alveolar bone surrounding deciduous teeth and palmoplantar hyperkeratosis of the skin. Increased susceptibility to infection has been reported among individuals with the cathepsin C (CTSC) gene mutation. This article reports a 7-year-old Japanese girl who presented with deciduous tooth...

Prevalence of double teeth in primary dentition of 0.5% was established in the sample of 2.987 preschool children of Zagreb. Between children with double teeth 60% were female and 40% males. Fusion ocurred in 66.7 percent and germination in 33.3 percent in the sample of children having double teeth. In all children with double teeth orthopantomograms were taken. Analysis of radiographs revealed...

The term anterior open bite, which means no contact between anterior teeth, stands out in current orthodontic by the complexity of the treatment, associated with high levels of instability and recurrence. The purpose of this study is to emphasize that early etiological diagnosis is essential to the successful outcome of the technical intervention. The bibliographical study shows that, once the ...

Primary tooth impaction is a rare finding during the development of primary dentition. Several factors contribute to the impaction of a deciduous tooth. This report describes the diagnosis and treatment of a 10-year-old boy who presented an impacted second primary mandibular molar. This tooth, located inferior to the second premolar together with an odontoma, was positioned superior to the prem...

Deciduous teeth (dentes lactales, dentes decidua, dentes caduci) differ from permanent teeth by morphological and histological characteristics. Of the morphological characteristics, the most pronounced differences are in number, shape, size and color of teeth. A special fea­ ture is the existence of enamel­dentin ridge located on the vestibular surface of molars, which protects gingiva from foo...

Secondary data from a randomized sample of Brazilian preschool children were analyzed to evaluate the prevalence of occlusal deviations in the deciduous dentition that can adversely affect the permanent dentition, using revised criteria. Overjet and overbite used cut-off points described in the literature to exclude mild malocclusion cases. Overjet > 3mm and overbite > 3mm were present in 16% a...

AIM Anterior open bite (AOB) is an occlusal anomaly commonly associated with oral habits (OH). The aim of this study was to determine the prevalence of OH as a risk factor for the AOB. MATERIALS AND METHODS A group of children aged between 3 and 12 years were observed. The statistical methodology included independent chi-square test, Fisher's exact test and binary logistic regression. RESUL...

BACKGROUND Tooth mortality is important in evaluating dental care as tooth loss is a reflection of cumulative effects of past disease and treatment practices. AIM The aim of this study is to analyze the pattern of tooth mortality among pediatric dental patients treated at the University of Benin Teaching Hospital, Benin City, Nigeria. SUBJECTS AND METHODS This was a retrospective study of p...

Subjects and Methods: This was a retrospective study of pa...

Background: Primary tooth impaction is quite rare during the development of primary dentition. Various factors contribute to the impaction of a deciduous tooth, including anklyosis, congenitally missing permanent teeth, defects in the periodontal membrane, trauma, injury of the periodontal ligament, precocious eruption of the first permanent molar, defective eruptive force, or a combination of ...
