Background and Aim: The proportion of smile is a useful tool for creating geometric smiles which are a critical aspect in esthetic dentistry. The aim of this study was to determine the effect of lip line position on acceptable Recurring Esthetic Dental (RED) proportion among lay people. Materials and Methods: A photograph of pose smile of a young female was taken. The position of the lip was c...

background: lip carcinoma is a common cancer with a good prognosis and when patients refer early in the course of disease the results of treatment are acceptable. surgical procedures for reconstruction of lip defects are the use of remaining lip tissue, tissue from the opposite lip, adjacent cheek tissue, distant flaps and microvascular free flaps. the bitemporal (visor) flap is a regional flap...

cleft lip and cleft palate are one of the most frequent congenital anomalies worldwide. this study was conducted in order to measure the frequency of cleft lip and palate among live births in akbar abadi hospital. this is a descriptive study, dealing with 57526 cases of live birth out of 59477 medical files in akbar abadi hospital from 2004 to 2008. all the collected data were recorded in speci...

Non-syndromic cleft lip/palate (NSCL/P) is a complex, frequent congenital malformation, determined by the interplay between genetic and environmental factors during embryonic development. Previous findings have appointed an aetiological overlap between NSCL/P and cancer, and alterations in similar biological pathways may underpin both conditions. Here, using a combination of transcriptomic prof...

conclusions although treatment of ec in the present study had considerable success in the short-term follow-up, it should be noted, due to the unknown of the exact cause, no specific treatment or protocol has still been identified. introduction exfoliative cheilitis (ec) is a rare chronic inflammatory condition affecting the vermillion border of the lips and characterized by excessive productio...

In this thesis a new multimodal speaker/speech recognition system that integrates audio, lip texture, lip geometry, and lip motion modalities is presented. There have been several studies that jointly use audio, lip intensity and/or lip geometry information for speaker identification and speech-reading applications. This work proposes using explicit lip motion information, instead of or in addi...

BACKGROUND The purpose of this study was to evaluate the association between the use of relaxing incisions and maxillary growth disturbance after primary palatoplasty in patients with unilateral cleft lip and palate. METHODS This is a prospective, randomized, double-blind controlled trial study with ethical committee approval between 2 groups of patients with unilateral cleft lip and palate w...

The aesthetic outcome of treatment has become increasingly important to patients having orthognathic surgery. The aim of this observational cohort study based on clinical records was to evaluate the effect of maxillary advancement on changes to the soft tissues. We studied 53 patients with class III malocclusion (29 women and 24 men, mean (SD) age 28 (11) years). We identified all patients trea...

BACKGROUND Most patients with facial scarring would value even a slight improvement in scar quality. Botulinum toxin A is widely used to alleviate facial dynamic rhytides but is also believed to improve scar quality by reducing wound tension during healing. The main objective was to assess the effect of Botulinum toxin on scars resultant from standardized upper lip wounds. METHODS In this dou...
