A thyroglossal cyst is a fibrous cyst that forms from a persistent thyroglossal duct.
It usually presents as a midline neck lump (in the region of the hyoid bone) that is usually painless, smooth and cystic, if infected pain can occur. There may be difficulty breathing, dysphagia (difficulty swallowing), and/or dyspepsia (discomfort in the upper abdomen), especially if the lump becomes large. Continue reading
PROBLEM: HERRING BONE OR TIRE-TRACK IMAGE
CAUSE: Film placed backward and then exposed. X-ray beam attenuated
by the lead foil backing in the film packet
ACTION: Always place the white side of the film adjacent to the teeth
Tear drop silicone – rubber stops have an added advantage because they do not have to be removed form the instrument during sterilization at 4500 F and tear drop tip can be positioned to indicate instrumental curvature
Rubber stops instruments have certain disadvantages like movement of up (or) down the shaft, leading to short (or) past the apical constriction and time consuming.

As with any other dental procedures, teeth extraction required specific dental instruments to do so. Unlike our baby teeth which could be easily pulled out when they are wobbly or would naturally drop off in their due times, adult teeth are a different matter altogether. Because of their longer root length and stronger surrounding supporting tissues, adult or permanent teeth (or even baby teeth that are not loose) would require certain techniques and dental tools to remove them.

An example of an oral cancer-squamous cell carcinoma
Oral or mouth cancers are any tumours that grows anywhere in the mouth. They are often associated with tobacco use. It is a condition of concern because some oral cancers are fatal if not detected and treated early, such as squamous cell carcinoma (SCC), which is due to uncontrolled proliferation of the squamous cells. Almost all oral cancers begin in the flat cells (squamous cell) that cover the surfaces of the mouth, tongue, and lips.

Teeth extractions are usually done to relieve dental pain or remove loose teeth. However even though your initial problem is solved, you have to take care of the tooth socket which the tooth was extracted or further complications may follow.
Post-operative care instructions would normally be provided by the dentist, in which you will have to follow. If there are any complications after your tooth extraction, always consult your dentist. Do not wait till the problem worsen. Continue reading
Taste buds contain the receptors for taste. They are located around the small structures on the upper surface of the tongue, soft palate, upper esophagus and epiglottis, which are called papillae. These structures are involved in detecting the five (known) elements of taste perception: salty, sour, bitter, sweet, and umami. Via small openings in the tongue epithelium, called taste pores, parts of the food dissolved in saliva come into contact with taste receptors. These are located on top of the taste receptor cells that constitute the taste buds. The taste receptor cells send information detected by clusters of various receptors and ion channels to the gustatory areas of the brain via the seventh, ninth and tenth cranial nerves.

Dental treatment is best carried out during the second trimester, but advanced restorative procedures are probably best postponed until the state of the gums improves after giving birth and prolonged sessions of treatment are better tolerated. In the second and third trimesters the fetus is growing and maturing but can still be affected by infections, drugs and possibly other factors. In the third trimester the supine hypotension syndrome may result if the pregnant woman is laid flat. The person should therefore be put on one side to allow blood return to recover. Some pregnant women also have a hypersensitive gag reflex. Elective dental care should be avoided in the last month of pregnancy, as it is uncomfortable for the patient. Moreover premature labor or even abortion may also be attributed, without justification, to dental treatment. Continue reading

Pregnancy is a major event in any woman’s life and is associated with physiological changes affecting especially the endocrine, heart and blood systems and often attitude, mood or behavior. Therefore pregnant women should take extra care during this period to avoid any circumstances that could harm their fetuses, including certain dental treatments. Continue reading
Rampant caries
Early Childhood Caries (ECC) is a chronic and infectious oral disease of young children, most commonly seen in poor and minority populations.
The American Dental Association (ADA) defines ECC as “the presence of one or more decayed (non-cavitated or cavitated lesions), missing (due to caries) or filled tooth surfaces in any primary tooth in a preschool-age child between birth and 71 months of ageâ€. Continue reading
