Dens invaginatus is an anomaly of the tooth formation of embryonic origin that presents itself in several morphologic types. The complex anatomy of these teeth makes nonsurgical endodontic treatment complex and more so when its apex is immature. The 2 cases reported illustrate the nonsurgical endodontic management of a dens invaginatus type II and type III with an immature apex and periapical l...

Let V be a finite dimensional real vector space. Let V alsm(V ) be the space of translation invariant smooth valuations on convex compact subsets of V . Let Dens(V ) be the space of Lebesgue measures on V . The goal of the article is to construct and study an isomorphism FV : V alsm(V )−̃→V alsm(V ∗)⊗Dens(V ) such that FV commutes with the natural action of the full linear group on both spaces, ...

Developmental dental anomalies refer to deviation from the normal size, shape, number or structure of external and internal anatomy of a tooth. Their presence have functional and clinical significance. With no definite reason some dental anomalies may occur commonly in some specific teeth like microdontia in maxillary lateral incisors, dens invaginatus in maxillary lateral incisors, dens evagin...

Many species have strong habitat preferences that directly influence population viability. For successful reintroduction of threatened populations that rely on habitat structures, the correct placement of artificial structures is also important to population persistence. In this paper, we present a hierarchical approach to the problem of translocating animals that rely on permanent habitat stru...

Dendrimer-templated nanoparticle synthesis is an efficient method for preparing a variety of monoand bimetallic nanomaterials, whose sizes are constrained by the loading capacity of the dendrimer template. A common commercially available dendrimer is composed of repeating amino-amide units (polyamidoamine, PAMAM), whose internal amines coordinate with free metal ions in solution. The metal ion ...

BACKGROUND Dens fractures are relatively common in the elderly. The treatment of Type-II dens fractures remains controversial. The aim of this multicenter prospective cohort study was to compare outcomes (assessed with use of validated clinical measures) and complications of nonsurgical and surgical treatment of Type-II dens fractures in patients sixty-five years of age or older. METHODS One ...

Most writers on the subject claim that chronic intussusception is rare in childhood. Thus Still (1921) stated that in children it occurs 'rarely indeed'; Monrad (1927) wrote: 'Chronic invaginations in my experience are extremely rare in small children'; Beaven (1929) noted that 'judging from the number of cases reported, chronic intussusception is an extremely rare disease in children'; and Nyb...

Introduction: Operation of appendix is very common abdominal surgery that is done by general surgeons. Some surgeon prefer to invaginate the appendix stump while others don’t. Aim of the study was to compare the technique of ligation and invagination of the appendix stump with simple ligation of the appendix stump during appendicectomy for acute appendicitis. Methods: A prospective comparative ...

Epithelial invagination is a common feature of embryogenesis. An example of invagination morphogenesis occurs during development of the early eye when the lens placode forms the lens pit. This morphogenesis is accompanied by a columnar-to-conical cell shape change (apical constriction or AC) and is known to be dependent on the cytoskeletal protein Shroom3. Because Shroom3-induced AC can be Rock...
