OBJECTIVES In dentistry, the results of in vivo studies on drugs, dental fillings or prostheses are routinely evaluated based on selected oral cavity environment parameters at specific time points. Such evaluation may be confounded by ongoing changes in the oral cavity environment induced by diet, drug use, stress and other factors. The study aimed to confirm oral cavity environment changeabili...

While initially the oral cavity was considered to be mainly a source of various bacteria, their toxins and antigens, recent studies showed that it may also be a location of oxidative stress and periodontal inflammation. Accordingly, this paper focuses on the involvement of melatonin in oxidative stress diseases of oral cavity as well as on potential therapeutic implications of melatonin in dent...

BACKGROUND Metastatic tumours to the oral cavity from distant organs are uncommon and represent approximately 1 - 3% of all oral malignancies. Such metastases can occur to the bone or to the oral soft tissues. Almost any malignancy from any site is capable of metastasis to the oral cavity and a wide variety of tumours have been reported to spread to the mouth. METHODS Careful examination of t...

Current biomarkers (DNA, RNA and protein) for oral cavity and oropharyngeal cancers demonstrate biological variations between individuals, rendering them impractical for clinical translation. Whilst these biomarkers originate from the host, there is not much information in the literature about the influence of oral microbiota on cancer pathogenesis, especially in oral cancers. Oral microbiotas ...

Imaging of the oral cavity and pharynx often is required in three settings: assessment of an inflammatory mass in association with odontogenic, tonsillar, or pharyngeal infections; determination of the cause of a submucosal mass; and staging of squamous-cell carcinomas. Spread of infection from the oral cavity and pharynx can lead to abscesses in the masticatory space, the retropharyngeal compa...

The oral cavity is not a preferred site for metastasis of distant cancers, accounting for only 1% of all oral cancers. Almost all types of cancers can spread to the oral cavity, and usually are late presentation. Sometimes the oral metastasis may manifest as a benign lesion and may cause challenges in its diagnosis. All patients with oral cavity metastasis diagnosed at King Hussein cancer cente...

Sinus ultrasound (3 MHz ultrasound wave) is ideal for detecting maxillary and frontal sinusitis as it propagates well through bone, soft tissues and fluids but not through air. Ultrasound is sent towards the bony back wall of a sinus cavity and the reflected echoes correlate to the depth of the tissue boundaries. A healthy sinus cavity, containing only air, reflects from the anterior wall of th...
