The aim of this review was to systematically assess the literature on cytotoxicity of root canal irrigants and intracanal medicaments on stem cells of the apical papilla. A structured strategy was employed and 7 papers were identified. The papers were analysed for concentration of agent used, testing method and viability of stem cells of the apical papilla (SCAP). Irrigation protocols using a f...

Dens invaginatus is a developmental anomaly that results in an invagination of the enamel organ into dental papilla prior to calcification tissues. Apical fenestration defined as defect which apices perforate mucosa and are exposed oral cavity. These anomalies require multidisciplinary management order give better prognosis patient, since it acts retentive area biofilm, affecting deteriorating ...

Premetamorphic papillae of an anuran tadpole (Rana japonica) were studied by scanning and transmission electron microscopy. Premetamorphic papillae of several shapes are seen in and around the oral cavities of tadpoles during late larval and early metamorphic stages. These papillae are composed of three parts: the apical cellular part, the underlying connective tissue core and the epithelial co...

Figure 1—A well-aligned, unworn dentition showing a normal relationship between contact length and papilla heights and papillae at the same level across the anterior. Figure 2—A classic presentation of periodontal disease showing apical migration of all the papilla and open gingival embrasures. Figure 3—The final restorations were created to close the open embrasures but this results in long co...

introduction: this in vitro study assessed and compared the cytotoxicity of mineral trioxide aggregate (mta), calcium-enriched mixture (cem) cement, biodentine (bd) and octacalcium phosphate (ocp) on stem cells of the human apical papilla (scap). methods and materials: scaps were isolated from two semi-impacted third molars. the cells were cultured in wells of an insert 24-well plate and were t...

Endocytic vesicles that are involved in the vasopressin-stimulated recycling of water channels to and from the apical membrane of kidney collecting duct principal cells were isolated from rat renal papilla by differential and Percoll density gradient centrifugation. Fluorescence quenching measurements showed that the isolated vesicles maintained a high, HgCl2-sensitive water permeability, consi...

Introduction: During the last decade, advances in tissue engineering and stem cell-based tooth regeneration have provided realistic and attractive means of replacing lost or damaged teeth. The first adult stem cells isolated from dental tissues were dental pulp stem cells (DPSCs). When transplanted with hydroxyl apatite/tri calcium phosphate (HA/TCP) powder, they formed a dentin-like structure...

The dorsal lingual surfaces of two adult Japanese marten (Martes melampus) were examined by scanning electron microscopy (SEM). Filiform, fungiform, vallate and foliate papillae were observed. A small filiform papilla on the apical surface of the tongue had several pointed processes. A small filiform papilla contained the connective tissue core consisting of several small processes. A large fil...

Despite the independent evolution of birds and mammals, a number of structural similarities of their hearing organs have developed in parallel. By tracing the peripheral origin of functionally-characterized primary neurons, the present study demonstrates functional similarities between the respective hair cell populations of the hearing organs of birds and mammals. The space devoted to one octa...
