RADIATION THERAPY AND DENTISTRY PART I

What is radiation therapy?

Using of ionizing radiation to kill cancer cells.

How does radiotherapy work?

Radiation therapy kills cells by interacting with the water molecules which are present in our cell. Charged molecules will be produced and distrupt the biochemical process of our cells. (DNA is damaged) Continue reading

Neonatal teeth

WHAT ARE NEONATAL AND NATAL TEETH?

Natal teeth are teeth which are present in the oral cavity at the time of birth where as neonatal teeth erupt during 30 days of life. Primary tooth normally starts erupting at about 6 months of age. Natal teeth might resemble normal primary teeth in terms of size and shape. However, they can be smaller, yellowish and root formation of the teeth may not be completed/total absence during the time of eruption. This lack of root development can cause  mobility of the neonatal tooth. Continue reading

Symptoms of chronic periodontal disease

Chronic periodontal disease is a disease which involves the destruction of gums and supporting tissues. This disease is often seen in adults and is the commonest cause of adult tooth loss. Before we proceed to discuss about the symptoms of chronic periodontal diseases, let us have a look at the characteristics of healthy gums. Continue reading

Recession of gums

What is gingival recession?

Gum recession occurs when your root surfaces are exposed as a result of apical migration of your gum position. The pattern of distribution of your gum recession, whether is localized (affect one or two teeth) or generalized (most teeth) is determined by the etiological factor of gum recession.  Studies have shown that gum recession of at least 1mm is present in more than 50 percent of the human population.

What is a frenectomy?

Frenectomy is a surgical procedure which involves the removal of frenum, a thin band of fibrous tissue covered with mucosa. Labial frenum can be found when you lift your upper lips and it connects the center of your upper lip to the gum tissues between your two front teeth. Lingual frenum is found extending from the floor of the mouth to the midline of your tongue. Continue reading

What is Crown lengthening?

Crown lengthening is a dental procedure which involves the removal of gum tissue, bone or both to expose a greater height of your tooth structure. It is normally done by a periodontist to increase a restoration’s retention or to improve the esthetics of your gums.  Crown lengthening can be done on one tooth, or to several teeth and the total surgery time will depend upon how many teeth are involved.

Drug Induced Gingival Enlargement

Drug induced gingival hyperplasia is one of the common causes of gingival enlargement.  

There are three types of drugs highly associated with gingival hyperplasia/enlargement :

1) Antiepileptic drug (Phenytoin)

 2) Immunosuppressive drug (cyclosporine) and 3) calcium-channel blocking drug (nifedipine).

Phenytoin is usually prescribed for the treatment of seizures where as calcium channel blocking drugs are used to treat heart diseases, angina and hypertension.

  The incidence of gingival enlargement is lower in patients who are taking cyclosporine compared to patients who are on phenytoin (Approximately 50 % of patients have gingival overgrowth). However, it can be very severe (covers the entire surface of teeth) when gingival enlargement occurs in patients who are taking cyclosporine.  Continue reading
