PURPOSE The influence of the modified process in the fiber-reinforced post and resin core foundation treatment on the fracture resistance and failure pattern of premolar was tested in this study. MATERIALS AND METHODS Thirty-six human mandibular premolars were divided into 4 groups (n = 9). In group DCT, the quartz fibre post (D.T. Light-post) was cemented with resin cement (DUO-LINK) and a c...

background: talon cusp is a rare dental anomaly characterized by a cusp‑like projection, often including the palatal surface of the affected tooth. the aim of the present study was to investigate the prevalence and characteristics of talon cusps in a group of turkish children. materials and methods: the study population consisted of 14,400 subjects who attended the clinics of the department of ...

It is well known that the primary function of a tooth is mastication. However, tooth fracture remains a major complication in endodontically-treated teeth. When the normal structure of a tooth is compromised by traumatic injuries, endodontic treatment remains the most viable option to maintain the tooth. However, endodontically treated teeth (ETT) exhibit greater brittleness and are more prone ...

By a cusp V we shall mean the image of the unit disk D under a bounded injective holomorphic map h into C whose derivative vanishes at exactly one point. The simplest example is the Neil parabola, given by h(ζ) = (ζ, ζ). See [3, 4] for background and theory on the Neil parabola, which is pictured in Figure 1. A generalization of a cusp is a petal. A petal is the image of the unit disk D under a...

Intentional tooth reimplantation can be an alternative treatment option for teeth with poor or hopeless prognosis where coronal and surgical endodontic treatment(s) are not possible. This technique may help to restore a natural tooth to function in preference to prosthesis/implant replacements. A 38-years old male was referred to private practice with persistent chronic apical periodontitis of ...

Objectives This study is aimed to introduce an unusual case of a female with two talon teeth on both maxillary lateral incisors. Case A 38-year-old female was referred to oral medicine department, Qom university of medical sciences for routin examinations. Bilateral maxillary talon cusp was observed on maxillary lateral incisors. Future evaluation revealed impaction of maxillary left canine an...

We define generalized Mellin transforms of mixed cusp forms, show its convergence, and prove that the function obtained by such a Mellin transform of a mixed cusp form satisfies a certain functional equation. We also prove that a mixed cusp form can be identified with a holomorphic form of the highest degree on an elliptic variety.
