Dentistry

The options to help patients with oral and perioral pain problems such as neuropathies, burning mouth syndrome, neuromas and neuralgias. Vehicle-carrier agents and bases have been developed that can penetrate the mucosa and cutaneous tissues and transport the active medication to the treatment site. Dentists have been using topical agents with increasing frequency as part of the therapeutic protocol for orofacial painful neuropathy.

Several topical intraoral medications are used in the treatment of oral ulcerations and infections, including antifungals; nonsteroidal anti-inflammatory drugs (NSAIDs); and corticosteroids. Because of their rapid onset and low side-effect profile, topical medications offer a distinct advantage over systemic administration for orofacial disorders. Medicated lollipops, lozenges, and adhering powders are ideal for keeping an antibiotic or antifungal in contact with an infected area in the mouth.

Topical Anesthetics

Methemoglobinemia (MHb) is a potentially serious blood condition and an uncommon adverse reaction known to be associated with benzocaine. This condition reduces the ability of red blood cells to deliver oxygen throughout the body, which can lead to bluish discoloration of the skin, nausea and fatigue. It can progress to stupor, coma and death. Almost all reported cases of benzocaine-induced MHb were associated with high-concentration preparations (14 percent to 20 percent benzocaine). Compounding pharmacies can formulate low concentration or benzocaine-free topical anesthetics, including combinations of other topical anesthetics such as lidocaine and tetracaine or prilocaine.

Treatment for Dry Mouth, Stomatitis, and Mucositis

Loss of saliva (xerostomia) is one of the most common complaints among patients who have received radiation therapy of the head and neck. Xerostomia contributes to radiation-induced periodontal infection, dental caries, osteoradionecrosis, and poor digestion of carbohydrates. Ask us about sialogogues (saliva stimulants) in customized dosage forms.

Transdermal application of NSAIDs such as ketoprofen results in significantly higher tissue levels beneath the site of application than are achieved with oral administration. Additionally, side effects such as gastrointestinal irritation are avoided.

The gag reflex can cause a patient considerable discomfort as well as interfere with dental procedures. An electrolyte tablet administered and retained intraorally a few minutes before the start of a procedure can suppress the gag reflex, allowing a mandibular block to be given with much greater ease, which further reduces the gagging reflex.

Tablets can be prescribed for home use for patients who can not properly perform oral hygiene procedures due to the gagging problem. Severe gaggers may need to repeat a dose in 15 to 20 minutes.

Some patients and dentists prefer to use electrolyte lollipops.

Topical application of anti-emetics in a gel formulation provides a rapid onset and offers an effective alternative to oral administration. Oral surgeons have found this formulation to be particularly useful.

Promethazine is commonly compounded for topical or transdermal application to treat nausea, vomiting, and vertigo, but this preparation may be used as an antiemetic for cases ranging from chemotherapy to motion sickness. The dose is typically 25mg for adults, and the dose is decreased for children. The gel is applied to an area of soft skin, such as the inside of the wrist or arm, the side of the torso, or the inside of the thigh. For children, the gel is often applied to the inside of one wrist, and then the wrists are rubbed together.

Compounding allows countless active ingredients to be incorporated into customized mouthwashes, gels, troches, etc. For example, to treat periodontal disease, antibiotics can be formulated as a mouthwash, or added to an oral adhesive paste or a plasticized gel that will maintain the contact between the tissue and medication for a prolonged period of time.

Metronidazole 25% in a lipogel-type base provides an efficient treatment of anaerobic infection when applied topically in the periodontal pockets.

Compounding dental mouthwashes or rinses may offer numerous advantages over commercially available dosage forms. Elixirs, syrups, and suspensions often contain preservatives such as alcohol which can cause reactions or gastrointestinal irritation, or sugar which makes the preparation undesirable for prolonged use in the mouth or for diabetic patients. A customized preparation without unnecessary excipients – i.e., a sugar-free, dye-free, lactose-free, and preservative-free dosage form – can eliminate concerns of palatability, alcohol content, and dyes which may stain exposed mucosa.

Various preparations are also available to treat burning mouth syndrome and anesthetic/analgesic and antibiotic/anti-infective mouthwashes are commonly requested.

Tranexamic acid solution (4.8%) used as a mouthwash has been used successfully to prevent postsurgical bleeding after oral surgery without dose modification of oral anticoagulants.
