OBJECTIVES The aim of this study was to evaluate transversally the clinical correlation between lower incisor crowding and mandible third molar. STUDY DESIGN Three hundred healthy volunteers (134 male and 166 female), aged 20.4 (±2.4) years-old were submitted to a complete clinical examination and filled up a questionnaire about gender, age, total teeth number and presence or absence of super...

The aim of the present work was to analyze the ultrastructure and mineral composition of the surface of the enamel on a molar with MIH, with and without acid etching. A permanent tooth without clinical MIH lesions (control) and a tooth with clinical diagnosis of mild and moderate MIH, with indication for extraction, were processed with and without acid etching (H3PO4 37%, 20") for observation w...

AIM The methods for the restoration of permanent molars and incisors affected by Molar Incisor Hypomineralisation are reviewed. The special problems associated with restoring these teeth, such as sensitivity, occlusion and aesthetics are discussed. The various options for restoration are outlined and recommendations made as to the appropriate types of restoration.

Molar incisor hypomineralization (MIH) affects the permanent incisors and molars, whose undermineralized matrix is evidenced by lesions ranging from white to yellow/brown opacities to crumbling enamel lesions incapable of withstanding normal occlusal forces and function. Diagnosing the condition involves clinical and radiographic examination of these teeth, with known limitations in determining...

The change in lower arch crowding 3-4 years after second permanent molar eruption was examined in 85 subjects, in relation to the angulation and change in angulation of molars and incisors relative to the mandibular plane using correlation and multiple regression analyses. Crowding increased significantly during the observation periods. Changes in molar and incisor angulation in both mesial and...

In one aspect, this study examined the tensile strength of coronal dentin, as a function of the location of incremental lines, in two types of teeth: human molar versus bovine incisor. In another aspect, tensile strength in coronal dentin was examined with tensile loading in two different orientations to the incremental lines: parallel versus perpendicular. There were four experimental groups i...

Kök malformasyonları çeşitli genetik ve çevresel faktörlerin bir sonucu olarak ortaya çıkabilmektedir. gelişimi sırasında meydana gelen problemler enfeksiyon, travma, kemoterapi veya radyasyon tedavisine bağlı oluşabilmektedir. Yakın zamanda tanımlanan dental anomali olan molar keser malformasyonu kök malformasyonu, daimi birinci dişlerin köklerinde görülen gelişim bozuklukları ile karakterized...
