BACKGROUND Human lateralized behaviors relate to the asymmetric development of the brain. Research of the prenatal origins of laterality is equivocal with some studies suggesting that fetuses exhibit lateralized behavior and other not finding such laterality. Given that by around 22weeks of gestation the left cerebral hemisphere compared to the right is significantly larger in both male and fem...

One of the most common signs of tiredness or fatigue is yawning. Naturally, identification of fatigued individuals would be helped if yawning is detected. Existing techniques for yawn detection are centred on measuring the mouth opening. This approach, however, may fail if the mouth is occluded by the hand, as it is frequently the case. The work presented in this paper focuses on a technique to...

Lip synchronization is the determination of the motion of the mouth and tongue during speech. It can be deduced from the speech signal without phonemic analysis, and irrespective of the content of the speech. Our method is based on the observation that the position of the mouth over a short interval of time can be correlated with the basic shape of the spectrum of the speech over that same inte...

Speech animation synthesis is still a challenging topic in the field of computer graphics. Despite many challenges, representing detailed appearance of inner mouth such as nipping tongue’s tip with teeth and tongue’s back hasn’t been achieved in the resulting animation. To solve this problem, we propose a method of data-driven speech animation synthesis especially when focusing on the inside of...

OBJECTIVES To evaluate radiotherapy effects (RT) on mandibular movements of patients with head and neck cancer (H&NC) and associate them to the variables: functional capacity, radiation field, disease staging, type of feeding, concomitant chemotherapy and total dose of RT. METHODS Twenty-six patients with H&NC were followed up at the RT service. Physical examination was performed in 3 follow ...

Temporomandibular Joint Disorder (TMD) is a non-dental musculoskeletal disorder that has complex and multifactorial etiology. The most frequent symptoms are pain in the masticatory muscles, front of ears, temporomandibular joint (TMJ); this can also be accompanied by clicking sounds locking. This study aimed to present case report trauma following odontectomy. A 22-year-old patient came with so...

BACKGROUND To study the rarity of mandibular coronoid process fractures and treatment strategies based on the displacement of these fractures. MATERIALS AND METHODS A retrospective study of 11 cases of coronoid process fractures among 307 treated cases from 2008 to 2013 was conducted. Six patients were treated conservatively and 5 underwent ORIF with associated fractures. A statistical analys...

BACKGROUND AND PURPOSE To prospectively investigate the impact of different patients' characteristics on quality-of-life (QoL) after (chemo)radiation for oropharyngeal cancer (OPC). MATERIALS AND METHODS Between 2008 and 2011, 207 patients were treated with 46-Gy of (chemo)-IMRT followed by a boost by means of IMRT, brachytherapy (BT), or Cyberknife (CK). QoL-assessment was performed using th...

abstract introduction. temporo-mandibular disorders (tmds) are a group of chronic and common disease that a lot of skeletal, dental and psychologic factors can have an effect on it. proposed treatment to control this disorder consists of wide variety of drugs and non-drugs methods beside dental treatment. some investigations have reffered to relation between tmds and some psychologic factors su...

The objectives of the study were to evaluate the outcome of Gap arthroplasty and Interpositional arthroplasty in terms of mouth opening for management of TMJ ankylosis. This Quasi experimental study was carried out in Oral & Maxillofacial Surgical unit, Khyber College of Dentistry, Peshawar from May 2006 to August 2007. Sixty patients of TMJ ankylosis seeking treatment for the first time, irres...
