Molar-incisor malformation (MIM) or molar root-incisor (MRIM) is a dental anomaly that affects teeth and maxillary central incisors. Even though, the etiology not exactly known, it has been reported several factors such as staphylococcal infection in neonatal period, neurological diseases meningitis hydrocephalus, ongoing medications, infectious premature delivery were effective. In this case r...

INTRODUCTION Riga-Fede disease is a rare pediatric condition in which chronic lingual ulceration results from repetitive trauma. Neonatal teeth or underlying neuro-developmental disorders which include Down syndrome are described as causative factors, but to the best of our knowledge, this is the first case report of both Down syndrome and natal teeth coexisting. The need for early extraction i...

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...

The term natal tooth describes the tooth present at the time of birth. This is a rare case report of 31 weeks old premature infant with natal tooth. There is very little literature reporting about the natal or neonatal teeth in premature infants and its management. Through this article we wish to bring awareness about the presence of natal tooth and its complications in premature infants and wh...

Neonatal laryngoscopy and endotracheal intubation often are required for prematurely born, low birthweight children. Previous studies have shown that these procedures are associated with a high prevalence of enamel hypoplasia of the maxillary anterior teeth. The present case report, which describes dilaceration of a left maxillary primary central incisor probably resulting from laryngoscopy, st...

Two fused cyclopentadithiophenebis(dicyanovinylene) derivatives (FCPDT-16 and FCPDT-C24) with a low-lying LUMO energy level (3.88 eV) and a rigid core structurewere successfully synthesized.They have good thermal stability and form highly ordered packing structures both in the bulk solid state and in thin films. The field effect transistors fabricated from a solution of these two compounds show...

A pyrene-fused phenazinothiadiazole that shows electron mobilities (μe = 0.016 cm(2) V(-1) s(-1)) two orders of magnitude higher than those reported for pyrene-fused pyrazaacenes is described.

Cleidocranial dysplasia (CCD; OMIM 119600) is a rare autosomal dominant skeletal dysplasia, which mainly characterized by persistently open or delayed closure of fontanelle, patent skull sutures, abnormal clavicles, pectus excavatum, short stature, supernumerary teeth, and sinus middle ear infections. It caused Runt-related transcription factor 2 ( RUNX2; 600211 ) mutations. Herein, we present ...
