Introduction to dental medications.

Dental Work as other medical fields , requiring application of therapeutics to treat, control, prevent, .... etc conditions.

Here, we are going to talk about different medications, drug classifications, doses, side effects, Interactions, brand names, ... etc.

the dental field contains a lot of diseases, Syndromes, Conditions altering the treatment modality and requiring different drugs, so that there are a lot of drugs to the dentist that may prescribe, furthermore, there are a lot of drugs that the dentists should know as they cause conditions in oral cavity, leading to a diagnosis of medical condition in the patient Or even may have interactions with drugs you're welling to prescribe.

Drugs used in dentistry are a lot, simply, can be classified into:

• Medications used to control pain and anxiety
• Analgesics
• Antibiotics
• Anesthetics
• Medications used to treat dental infections
• Antifungals
• Other dental medications

----------------------------------

Chapter One: Medications used to control pain and anxiety

Dental treatment includes pain, In almost all the procedures ex: reduction, cavity preparation, surgery, sublingual scaling, … etc., then, the dentist should be care about this point, because, the dental Client (Patient) who comes to the dental office seeking treatment is almost nearly 90% afraids from what is called a dentist, then it becomes one of the most important success factors of the dentist in his work in the point of view of the patient is feeling comfortable in treatment without pain. AS one of the most reported Complication by clients is PAIN.

Dental Procedures is then accompanied with control of pain and sedation, with different procedures, including psychological control of pain, medication, anesthesia, sedation, Anxiety reduction protocol, and much more.

Here In this article we will discuss those drugs that include control of pain and anxiety, but NOW in this part of the article we will discuss the general view of the next chapters.

Several medications are available to help create more relaxed, comfortable dental visits. Some of the medications make the client feel no pain during the treatment, while the others can make him relax and others make him sleep completely.

----------------------------------

How can we choose the way to control pain and anxiety for the Client?

First of all, the dentist should discuss with the patient the procedures that will be done, the overall health of the client, history of allergies and your anxiety level befor any approach is to be chosen.

----------------------------------

Basics to follow when choosing drug for relieving pain.

Analgesics are the drugs that are used for relieving pain, the Minor dental procedures (Non-surgical) requires a little relieving drugs, so the Non-narcotic are the drugs of choice, while the more invasive surgical procedures including oral and maxillofacial surgeries requires the narcotic analgesics as it works in the CNS (will be discuss later in the Chapter Three).

Before the dental procedure is to take place, the dentist should decide to put the client in the status of “FREE OF PAIN” then the anesthesia should be taken in consideration. The Anesthesia is classified into local and general anesthesia, while most of dental procedures requires the local, then it be used in almost all the cases, but the general anesthesia will be used in Oral and Maxillofacial surgeries, in completely un-cooperative patients or for child patient where the cavity preparation is nearly impossible.

Anxiety is a psychological and physiological state characterized by somatic, emotional, cognitive, and behavioral components.[2] It is the displeasing feeling of fear and concern. (Wikipedia)
