Read My Lips Asymmetries in the Visual Expression and Perception of Speech Revealed Through the McGurk Effect
Psychological science, 2004Co-Authors: Michael E. R. Nicholls, Dara A. Searle, John L. BradshawAbstract:It is well known that the right side of the Mouth moves more than the left during speech, but little is known about how this asymmetry affects lipreading. We investigated asymmetries in the visual expression and perception of speech using the McGurk effect—an illusion in which incongruent lip movements cause listeners to misreport sounds. Thirty right-handed participants watched film clips in which the left, the right, or neither side of the Mouth was covered. The McGurk effect was attenuated when the right side of the Mouth was covered, demonstrating that this side is more important to lipreading than is the left side of the Mouth. Mirror-reversed images tested whether the asymmetry was the result of an observer bias toward the left hemispace. The McGurk effect was stronger in the normal than in the Mirror orientation when the Mouth was fully visible. Thus, observers attend more to what they think is the right side of the speaker's Mouth. Asymmetries in Mouth movements may reflect the gestural origins of...

Oral health conditions among people visiting a medical center for health checkups.
Journal of the Formosan Medical Association = Taiwan yi zhi, 1993Co-Authors: Chun-i Huang, Chao-hung Hung, Wei-chieh Tseng, Chee-jen ChangAbstract:The purpose of this study was to evaluate the oral health conditions of subjects in a southern Taiwan health checkup program. One half of the examinees were selected randomly for oral examination during a two-year period. There were 537 subjects, including 286 men and 251 women with mean ages of 49.7 +/- 13.5 years and 50.2 +/- 12.1 years, respectively. Oral examinations included periodontal condition and existence of dental caries. The periodontal treatment needs of all examinees were evaluated using the Community Periodontal Index of Treatment Needs system and the World Health Organization periodontal probe. Dental caries examination was performed by the visual-tactile method with a Mouth Mirror and explorer. No radiographs were taken. All clinical evaluations were performed by the first author, who has experience in all of the indices. The results showed that only 0.7% of the subjects had no need of periodontal treatment, 6.7% had bleeding after gentle probing, and 75.2% presented with calculus, overhanging restorations, or pockets of 4 or 5 mm. The remaining 17.3% had pocket depths of 6 mm or deeper. There was no statistically significant difference between males and females in periodontal treatment needs and the mean number of decayed teeth (D). According to this hospital-based observation, most of the people in the health checkup program were in need of periodontal treatment, including oral hygiene instruction, prophylaxis and root planing. Approximately one-fifth of the subjects needed complex periodontal treatment; there were no differences in the treatment needs of males and females.(ABSTRACT TRUNCATED AT 250 WORDS)

evaluation of glass carbomer sealant and a moisture tolerant resin sealant a comparative study
International Journal of Dental Sciences and Research, 2015Co-Authors: Priya Subramaniam, Shurti Jayasurya, K Girish L BabuAbstract:Abstract Introduction Fissure sealants have been widely used for more than four decades in preventing dental caries. Advances in technology have led to the development of moisture tolerant sealants. They are available as resin based and glass ionomer based. There is a paucity of studies on the effectiveness of moisture tolerant sealant materials in clinical conditions. AIM: The aim of the present study was to evaluate and compare the retention and caries incidence with use of the two newly introduced moisture tolerant pit and fissure sealants. Materials and methods One hundred and eight children formed the study group. The glass carbomer sealant and Embrace WetBond sealant were two moisture tolerant sealants used. The sealant was applied on the occlusal surface of the teeth following the manufacturer's instructions. Children were recalled for assessment of sealant retention and the teeth were examined for dental caries on the occlusal surface using Mouth Mirror and blunt probe following 1, 3,6,12,18 and 24 months. Sealants were assessed according to a modified version of the CCC sealants evaluation system described by Deery et al. RESULTS: At 18 and 24 months, both GC and EBW showed similar pattern of sealant retention At 24 months, enamel caries was observed in 3 teeth sealed with EBW as compared to only 1 tooth sealed with GC. Conclusions There was no significant difference between the retention of glass carbomer sealant and Embrace WetBond sealant, at the end of 2 years. There was no significant difference in the caries incidence between both these sealants.

Prevalence of oral lesions in patients with type 2 diabetes in north Kerala population
Journal of Diabetology, 2020Co-Authors: Jinisha Madathil, Haris Padippurakkakath Salim, Anita Balan, Chandni Radhakrishnan, Nileena R KumarAbstract:Objective: To assess the prevalence of oral lesions in Type 2 Diabetic patients. Methods: The study was conducted in Outpatient Department and Diabetic Clinic of Government Medical College, Kozhikode and Department of Oral Medicine and Radiology, Government Dental College, Kozhikode over a period of 1 year. A total of 800 individuals 400 Type 2 Diabetes Mellitus patients and 400 healthy individuals were enrolled in this study. An oral clinical examination was carried out for all participants using a Mouth Mirror, visible light source and cotton gauze. Results: Prevalence of oral lesions was significantly high P 0.05) association was found between Type 2 Diabetes Mellitus and Potentially malignant oral mucosal lesions and also no association was found between oral lesions and metabolic control of the disease. Conclusion: This study showed that the prevalence of oral lesions was higher in Type 2 diabetic than non - diabetics and provides evidence that diabetes can have a negative influence on oral health.
