INTRODUCTION In attempting to provide a solution for cases that have been compromised by malpositioned anterior teeth, clinicians traditionally decide orthodontic approach. Nevertheless, in some cases changes in tooth morphology, tooth size, and shape is compulsory for optimal aesthetics. The advent in contemporary aesthetic materials and preparation techniques empowered the clinicians to deliv...

Introduction: The number, size, shape, and structure of teeth in humans show very wide variation among different populations and sometimes within the same population. The aim of the present study was to determine the prevalence of developmental dental anomalies among patients attending the faculty of dentistry in Rasht, Iran over a period of seven months. Materials and methods: This cross-se...

Objectives: This review article is aimed to determine panoramic radiograph images of complex odontoma involving impacted teeth.
 Review: study a scoping consisting English or Indonesian articles in teeth and published 2010 – 2021. The search databases used were PubMed, Science Direct, EbscoHost, Clinical Key with the keyword “(((Complex Odontoma) AND Impacted teeth) radiograph).” selected ...

Hydroxyapatite (HA) is the most important bioactive ceramics because of biocompatibility and structural similarity to the mineral part of bones and teeth of broad clinical application in the field of dentistry, orthopedic and coatings are Biomaterials. The aim of this study was to construct nano-hydroxyapatite micro particles using calcite, silica and zinc oxide using ball milling, powder, thes...

Ectodermal dysplasia is a heterogeneous condition characterized by affected ectodermal structures, among which the teeth and skin with its derivatives (hair sweat glands) are the most frequent. The aim of this work is to present the analysis of dental traits in five families (affected boys and their mothers) with hypohidrotic ectodermal dysplasia (HED), and to evaluate the importance of orofaci...

Objectives: The aim of this literature review was to analyze the root canal shape of human teeth described in anatomical studies as recent wide use of fiber posts resulted in a new interest for the anatomy of coronal and middle portions of the canal, where post-space should be prepared, in order to achieve the best fiber post fitting to the post-space. Material and methods Original scientific p...

A patient of 58 years of age without medical problems came to the clinic due to missing teeth in the upper posterior region and to change the partial fixed prosthesis in the upper anterior area. Proposed treatment: surgical phase of three conical shape tapering implants with prosthetic platform in occlusal direction with mechanize collar tissue level with fixtures to place implant-supported met...

AIMS Presenting a new method for direct, quantitative analysis of enamel surface. Measurement of adhesive remnants and enamel loss resulting from debonding molar tubes. MATERIAL AND METHODS Buccal surfaces of fifteen extracted human molars were directly scanned with an optic blue-light 3D scanner to the nearest 2 μm. After 20 s etching molar tubes were bonded and after 24 h storing in 0.9% sa...

Fusion of teeth is a developmental anomaly. It occurs at the stage of tooth formation, which determines the shape and size of the tooth crown, when one or more teeth fuse at the dentin level during the morphodifferentiation of the dental germs. Such teeth show macrodontia and may cause crowding, as well as esthetic and endodontic problems. In this article, we report a rare case of a maxillary c...

Newly discovered fossils of the Middle Triassic reptile Atopodentatus unicus call for a radical reassessment of its feeding behavior. The skull displays a pronounced hammerhead shape that was hitherto unknown. The long, straight anterior edges of both upper and lower jaws were lined with batteries of chisel-shaped teeth, whereas the remaining parts of the jaw rami supported densely packed needl...
