Failure of eruption of primary teeth can be considered rare, especially in maxillary anterior teeth. The problem can be either mechanical obstruction of eruption or a failure of the eruption mechanism. This case report presents failure of eruption of the maxillary right deciduous central incisor in a 4-year-old girl. The unerupted primary tooth was removed surgically. The histological finding r...

AIM Impaction of deciduous teeth is an uncommon event. The purpose of this report is to describe two unusual eruption failures of a second primary molar and their treatment management. CASE REPORT The diagnostic and therapeutic protocol of two cases selected at the Unit of Paediatric Dentistry, Department of Oral and Maxillofacial Science, "Sapienza" University of Rome, Italy, are presented. ...

AIMS This article aimed to characterize the incidence of supernumerary teeth in Turkish children according to sex, location, number and morphology and to explore possible correlations between these variables. METHODS The study population comprised 7,551 non-syndromic patients aged 3-16 years who applied for routine check-ups at the Ankara University Department of Pediatric Dentistry between J...

Human teeth are diphyodont excepting the permanent molars. The deciduous teeth are, ontogenetically considered, the first generation of teeth. The permanent teeth (except molars) belong to the second dentition. The term " third dentition " (also called the postpermanent dentition) refers to the opinion that one more set of teeth can occur in addition to the permanent teeth. The processes by whi...

OBJECTIVES The purpose of this study was to determine the Young's modulus and the hardness of deciduous and permanent teeth following wear challenges using different dental materials. MATERIALS AND METHODS Wear challenges were performed against four dental materials: A resin-based fissure sealant (Fluoroshield(®)), a glass ionomer based fissure sealant (Vitremer(®)), and two microhybrid compo...

OBJECTIVE The aim of this study was to compare the production of the chemokines CCL3 and CXCL12 by cultured dental pulp fibroblasts from permanent (PDPF) and deciduous (DDPF) teeth under stimulation by Porphyromonas gingivalis LPS (PgLPS). MATERIAL AND METHODS Primary culture of fibroblasts from permanent (n=3) and deciduous (n=2) teeth were established using an explant technique. After the f...

INTRODUCTION Human dental pulp stem/stromal cells (hDPSCs) in adults are primarily derived from the pulp tissues of permanent third molar teeth in existing literatures, whereas no reports exist, to our knowledge, on deriving hDPSCs from a tooth without the need for surgical procedure. The aim of this study was to raise a novel idea to source hDPSCs from complicated crown-fractured teeth requiri...

Transposition of teeth is a severe problem, which usually affects the cuspid-first premolar area. It is frequently associated with other dental anomalies such as tooth agenesis, peg-shaped maxillary lateral incisors, retained deciduous teeth, malpositions of the adjacent teeth and other teeth malformations. This paper describes the orthodontic management with fixed appliances of a case of bilat...

BACKGROUND Mutations in WDR72 have been identified in autosomal recessive hypomaturation amelogenesis imperfecta (AI). OBJECTIVE to describe a novel WDR72 mutation and report the ultrastructural enamel phenotype associated with a different WDR72 mutation. METHODS A family segregating autosomal recessive hypomaturation AI was recruited, genomic DNA obtained and WDR72 sequenced. Four deciduou...

BACKGROUND Scientific evidence showed that rapid maxillary expansion (RME) affects naso-maxillary complex, increasing nasal width and volume. This study aimed to evaluate nasal changes induced by rapid maxillary expansion with different anchorage and appliance design by using low dose and cone beam computed tomography. METHODS A total of 44 patients (20 males, mean age 8y 8 m ± 1y 2 m; 24 fem...
