oral health problems, among the most prevalent comorbidities related to addiction, require more attention by both clinicians and policy-makers. our aims were to review oral complications associated with drugs, oral health care in addiction rehabilitation, health services available, and barriers against oral health promotion among addicts. drug abuse is associated with serious oral health proble...

background: qat (also known as khat , kat and miraa ) is a green-leaved plant ( catha edulis ). it is a shrub indigenous to yemen and certain parts of eastern africa. chewing the leaves, which have sympathomimetic and euphoric effects, has been documented in many countries and increased with worldwide migration. the effect of long-term chewing qat on the oral cavity is unknown. objective: a sys...

OBJECTIVE Oral inflammatory pathologies are linked to increased oxidative stress, thereby partly explaining their relevance in the etiology of systemic disorders. The purpose of this work was to determine the degree to which LPS from Porphyromonas gingivalis, the primary pathogen related to oral inflammation, altered gingival mitochondrial function and reactive oxygen species generation. METH...

There are about 600 million people with the betel quid (BQ) chewing habit throughout the world (1). Studies showed that chewing BQ is associated with oral diseases, e.g. oral submucous fibrosis (OSF), oral leukoplakia (OL), and oral cancer (2-5). In addition, the alkaloid extracts from BQ have been characterized as carcinogenic (3-5), immunosuppressive, hepatotoxic (6), immunotoxic (7), genotox...

OBJECTIVE The purpose of this study was to investigate the relationship between the presence of abnormal oral reflexes and speech sound production in children with severe cerebral palsy. MATERIALS & METHODS Seven oral reflexes such as, rooting, mouth-opening, biting, chewing, lip, tongue, and suckling were examined in 52Persian-speaking monolingual children with spastic cerebral palsy (ages 5...

This study examines the impact of syntactic priming on production of indirect questions/requests by Persian learners of English as a foreign language (EFL). Eighty learners participated in two experiments investigating the impact of syntactic priming on oral production and the possibility of transfer of the priming effects to a different modality. A Production experiment showed that priming res...

To investigate the neural network of overt speech production, event-related fMRI was performed in 9 young healthy adult volunteers. A clustered image acquisition technique was chosen to minimize speech-related movement artifacts. Functional images were acquired during the production of oral movements and of speech of increasing complexity (isolated vowel as well as monosyllabic and trisyllabic ...

Many natural dietary products prevent or cure allergic inflammation; however, the ability of mixtures of these natural medicinals to suppress allergic skin inflammation is unknown. We examined the inhibitory effects of nonanatural products mixture (NPM-9), which provides immunoregulatory activation, on Th2-mediated skin allergic inflammation. Oral administration of NPM-9 in mice reduced ear thi...
