Purpose: To explore and analyze the curative effects of micro implant anchorages in orthodontics. Methods: A retrospective analysis of 65 patients undergoing orthodontic treatment in Department of Stomatology, Binzhou Medical University Hospital, Shandong, China was carried out. Thirty four cases in the treatment group were treated with a micro-implant as the anchorage, while 31 cases of the co...

Stem cells are essential for the regeneration and homeostasis of many organs, such as tooth, hair, skin, and intestine. Although human tooth regeneration is limited, a number of animals have evolved continuously growing teeth that provide models of stem cell-based organ renewal. A well-studied model is the mouse incisor, which contains dental epithelial stem cells in structures known as cervica...

We investigated the distribution of cortical, callosal, and thalamic connections from the primary somatosensory area (S1) in naked mole-rats, concentrating on lower incisor and forelimb representations. A neuronal tracer (WGA-HRP) was injected into the center of each respective representation under guidance from microelectrode recordings of neuronal activity. The locations of cells and terminal...

Dental trauma can lead to a wide range of injuries of which crown and root fractures are examples. Crown-root fractures often need complex treatment planning. This case report describes the use of MTA in the multidisciplinary management of a patient with a horizontally fractured central incisor and luxation in a different central incisor. A 42-year-old female patient presented within 1 h of rec...

tooth impaction rarely occurs in primary dentition. most of the primary teeth impactions are seen in second molars. the purpose of this article is to present a 4-year-old girl with bilateral impaction of inverted primary maxillary central incisors which trauma had displaced their tooth germ before erupting.

We report a rare case of a two-rooted maxillary central incisor, stressing the importance of three-dimensional imaging in treatment planning and conservative approach of management. Endodontic treatment of this central incisor was carried out with a successful outcome.

Abnormal morphology of the root canal may exist in any tooth, even a maxillary central incisor. In this paper we report endodontic treatment for a rare example of a maxillary central incisor with one root and three root canals.

introdouction: esthetic demands of patients have led to the introduction of tooth-colored restorations wherecomposite resins are bonded to the enamel using acid etch techniques. total etch adhesion systems are still considered as the gold standard among bonding systems. however, clinicians have a tendency to use adhesive systems with simpler application procedures. the aim of the present study ...
