OBJECTIVES To assess the bone density in maxilla and mandible in dentate and edentulous patients in Saudi population. METHODS This study involved a retrospective analysis of cone beam CT images of 100 patients (50 male and 50 female) who have come to College of Dentistry, University of Dammam, Dammam, Kingdom of Saudi Arabia between January 2014 and 2015. Using the bone density option in the ...

Different from humans, who have a continuous dentition of teeth, mice have only three molars and one incisor separated by a toothless region called the diastema in the hemi mandibular arch. Although tooth buds form in the embryonic diastema, they regress and do not develop into teeth. In this study, we evaluated the proteins that modulate the diastema formation through comparative analysis with...

The frequencies and chronology, based on a standard tooth development chart, of enamel hypoplasia derived from permanent upper central incisors and mandibular canines were compared for 42 prehistoric Amerindians. Between 0.5 and 4.5 years, when the crowns of both these teeth are developing, hypoplasias were 1.36 times more common on the incisors (54 hypoplasias/incisor; 40 hypoplasias/canine). ...

AIM The purpose of this case report is to present a case of a non-syndrome male patient with multiple supplemental supernumerary teeth in three quadrants of his mouth. BACKGROUND Supernumerary teeth are described as the teeth formed in excess of the number found in a normal dentition. Prevalence of supernumerary teeth varies between 0.1% and 3.8% in the general Caucasian population. Multiple ...

In the permanent dentition, the type of congenital missing teeth varies from author to author and the demographic and geographic profiles. In Europeans, the mandibular second premolar is the most frequently absent tooth, followed by the maxillary lateral incisor and the maxillary second premolars (Bergstrom, 1977; Rolling, 1980; O'Dowling & McNamara, 1990; Aasheim & Øgaard, 1993; Nordgarden et ...

The purpose of this study was to assess the prevalence of permanent incisor crowding in the maxillary and mandibular arches among Saudi schoolchildren. Three hundred and fifty four dental casts of Saudi schoolchildren attending pediatric dentistry and orthodontic clinics in College of Dentistry at King Saud University in Riyadh, Saudi Arabia were studied by one examiner. The children’s age rang...

this case report presents endodontic management of a mandibular lateral incisor with three canals using surgical dental operating microscope. this study describes the root canal variation of mandibular lateral incisor and highlights the importance of surgical operating microscope in detecting an unusual canal morphology.

Lateral luxation of permanent teeth is a common injury, and the most frequent post-injury complications is Pulp Canal Obliteration (PCO) followed by pulp necrosis and root resorption. This report presents two different prognoses for symmetrical immature maxillary central incisors after lateral luxation in a 7-year-old boy. Both teeth were laterally luxated and the gingiva distal to the left inc...
