INTRODUCTION Periapical inflammation is often responsible for distinct maxillary sinus (MS) changes. This retrospective, cross-sectional study evaluated the association between the clinical characteristics of periapical lesions (presence, size, and distance) in maxillary posterior teeth and the presence of sinus abnormalities by evaluating cone-beam computed tomographic (CBCT) images obtained f...

Componeer is an emerging esthetic solution for the treatment of discolored, fractured, or congenitally malformed teeth, which once required full-coverage restorations. Componeers combine the superior esthetic of ceramic veneers, and the bondability to tooth structure like direct composite veneers. Precontoured enamel shells with excellent color stability, no laboratory procedure, and cost effec...

OBJECTIVES To determine the epidemiology and describe the clinical and radiographic characteristics, the type of treatment, and the possible delayed appearance of new supernumerary teeth in patients with non-syndromic multiple hyperdontia. PATIENTS AND METHODS We conducted a small retrospective observational study of 8 patients diagnosed with non-syndromic multiple hyperodontia. Multiple hype...

AIM The aim of this article is to report a case of bilateral multiple impacted supernumerary teeth. A discussion of possible mechanisms of development is also presented along with a concise review of the literature. BACKGROUND Supernumerary teeth occur in the context of various scenarios in the primary and the permanent dentition. Multiple supernumerary teeth are a rare finding especially in ...

The purpose of this article is to describe the clinical features of otodental syndrome. A 9-year-old boy presented with dental abnormalities that have been described for otodental syndrome. The characteristic findings included large bulbous crowns in canine and molar teeth of both dentitions, deep vertical enamel fissures separating the cusps of affected molars, and hypoplastic yellow areas on ...

One of the most common dental anomalies is dens invaginatus. As the name indicates, it is an invagination of the coronary or root surface, bounded by enamel, which can be so profound as to simulate the appearance of a tooth inside another. Usually occurs in permanent maxillary lateral incisors, followed by maxillary central incisors, premolars, canines and less frequently molars. In this articl...

A search of literature published through the spring of 1986 yielded approximately 95 citations for the following embryonic organs in culture: kidney, pancreas, skin, palate, craniofacial tissue, tooth, lens, bones, digits, and liver. However, only the in vitro organ culture of the palate and tooth are reviewed in this paper. The other organ culture systems were not reported as teratogenic scree...

The aim of this paper is to report the oral signs and symptoms of four patients with Kabuki syndrome. All had oral abnormalities affecting the palate, teeth, and/or lips, including wide spacing between the teeth, screwdriver-shaped upper incisors, hypodontia, delayed tooth eruption, narrow spacing in the upper canine area, large pulp chambers of the upper incisors and permanent molars, external...

Disturbances involving abnormalities in tooth eruption are named ectopia. Transmigration is the name assigned to ectopia in the presence of teeth in areas distant from the alveolar process. Initial angulation of the tooth bud of the second premolar and premature loss of permanent mandibular 1st molars can influence the distal migration of the second premolar. Some studies have observed that ect...
