The ability to perform hygroscopic movements has evolved in many plant lineages and relates to a multitude of different functions such as seed burial, flower protection or regulation of diaspore release. In most mosses, spore release is controlled by hygroscopic movements of the peristome teeth and also of the spore capsule. Our study presents, for the first time, temporally and spatially well-...

BACKGROUND Knowledge about root canal morphology and its frequent variations can exert considerable influence on the success of endodontic treatment. The aim of this study was to survey the root canal morphology of mandibular first premolar teeth in a Gujarati population by decalcification and clearing technique. METHODS One hundred thirty eight extracted mandibular first premolar teeth were ...

BACKGROUND Teeth are integrated into the vertebrate oral jaws to provide a functional unit for feeding, however little is known about how this integration occurs during growth and development. The purpose of this study is to identify the ontogenetic changes in oral jaw shape that are associated with the transition of the oral dentition from unicuspid teeth to multicuspid teeth. Here, we compare...

this case report refers to the esthetic and functional restorations of extensively damaged maxillary central incisors with dental caries in a 32-year-old woman, with the use of posts and crowns made from natural extracted teeth. proper restoration of such teeth with the use of natural teeth fragments are known as “biological restoration.” biological restorations can be done by using the fragmen...

AIM To determine the position and shape of the apical foramina in posterior teeth derived from an Indian population. METHODOLOGY A total of 800 freshly extracted maxillary and mandibular premolar and molar teeth from a native Haryana population were collected. Apices of teeth were stained with methylene blue and then examined stereomicroscopically (40x). The following observations were made: ...

Non-Carious Cervical Lesion (NCCL) is the loss of hard tooth tissue at the cement-enamel junction not caused by caries and it was categorized in V-shape and saucer-shape according to the shape of the lesion on the plat surface. NCCLs often occurred on the buccal or labial surfaces of the teeth, especially the first premolars [1]. The tendency of distribution of NCCLs which maxillary teeth were ...

Teeth are one of the most important and popular biometric characteristic used in Forensic Dentistry. The development of automatic or semiautomatic, robust and precise forensic human identification systems are crucial for forensic, principally in mass disasters, like tsunamis and airplanes crashes. In this work we propose the use of the Differential Image Foresting Transform (DIFT) to extract th...
