Objective: The aim of present study was to investigate the difference of torque control during intrusion force in incisors with normal, under and over-torque in lingual and labial orthodontic systems through finite element analysis. Material and Methods: 3D models of an upper right central incisor with different torques were designed in Solid Works 2006.The models were transferred to the ANSYS ...

Orthodontic treatment with fixed appliances is considered a risk factor for the development of white spot caries lesions (WSL). Traditionally, brackets are bonded to the buccal surfaces. Lingual brackets are developing rapidly and have become more readily available. Buccal surfaces are considered to be more caries prone than lingual surfaces. Furthermore, lingual brackets are shaped to fit the ...

BACKGROUND Inter-foraminal implant placement poses a risk to the sublingual artery as it enters the mandibular midline lingual foramen. Lack of consensus on the source of this artery poses a dilemma to surgeons during management of haemorrhagic episodes. Determination of the exact source of this artery is therefore pivotal. METHODS This was a cross-sectional descriptive study involving 34 adu...

BACKGROUND This study was performed to evaluate the treatment effects of the antero-posterior lingual retractor (APLR), focusing on the 3-dimensional (3D) tooth movement of the maxillary anterior teeth and their alveolar bone levels. METHODS En masse retraction was performed using either the C-lingual retractor (CLR, C-group, n = 9) or the antero-posterior lingual retractor (APLR, AP-group, n...

OBJECTIVE To describe a technique for socket augmentation in molar extraction sockets with severe bone wall defect. METHODS Five teeth in four patients were included in this study. Each tooth had buccal and/ or lingual bone loss identified by bone sounding and periapical radiographs before removal. After a flapless, minimally invasive tooth extraction, the socket was grafted with deproteinize...

Neural changes related to the learning of the pronunciation of Chinese characters in English speakers were examined using fMRI. We examined the item-specific learning effects for trained characters and the generalization of phonetic knowledge to novel transfer characters that shared a phonetic radical (part of a character that gives a clue to the whole character's pronunciation) with trained ch...

In this paper we describe a joint effort by the City University of New York (CUNY), University of Illinois at Urbana-Champaign (UIUC) and SRI International at participating in the mono-lingual entity linking (MLEL) and cross-lingual entity linking (CLEL) tasks for the NIST Text Analysis Conference (TAC) Knowledge Base Population (KBP2011) track. The MLEL system is based on a simple combination ...

Due in large part to the popularity and global nature of the Web, multi-lingual issues in computers is finally beginning to attract serious attention, from users and developers alike. At the Software Labs in NTT, we are involved in a project that confronts multi-lingual issues in a big way. Namely, we are building software designed to self-configure a global distributed search infrastructure. T...

Lingual lipase is usually secreted from von Ebner's glands, although there is great variation between species. Lingual lipase is thought to be an auxiliary enzyme for fat digestion and absorption in mammals; however, the reason for lipolysis in the oral cavity is not known. We focused on the gustatory sense and investigated the significance of lingual lipase in the perception of a fat taste by ...
