**Glossary/Definitions of Terms** **Angular cheilitis:** a common inflammatory condition affecting the corners of the mouth or oral commissures. **Bacteremia:** the presence of bacteria in the blood.[^1^](https://www.dentalcare.com/en-us/ce-courses/ce628/references#1) Bacteremia can result from ordinary activities like vigorous toothbrushing, dental/medical procedures, or from infections.[^2^](https://www.dentalcare.com/en-us/ce-courses/ce628/references#2) **Cardiac dose of epinephrine:** limiting the use of vasoconstrictor in local anesthetic to 0.04 mg or 2 cartridges of 1:100,000 epinephrine. **Co-morbidity: **the simultaneous presence of two or more diseases or medical conditions in a patient. **Ecchymosis:** a discoloration of the skin resulting from bleeding underneath, typically caused by bruising. **Evidence-based dentistry (EBD):** the integration of the dentist's clinical expertise, the needs and preferences of the patient, and the most current, clinically relevant evidence. The three components are all considered during the decision-making process for patient care.[^3^](https://www.dentalcare.com/en-us/ce-courses/ce628/references#3) **Fibrinolysis:** the enzymatic breakdown of fibrin.[^4^](https://www.dentalcare.com/en-us/ce-courses/ce628/references#4) **Infective endocarditis:** infection within tissues lining the heart or within valves of the heart, caused by bacteria within the circulating blood that infect these cardiac issues.[^1^](https://www.dentalcare.com/en-us/ce-courses/ce628/references#1) **International Normalizing Ratio (INR):** a system established by the World Health Organization (WHO) and the International Committee on Thrombosis and Hemostasis for reporting the results of blood coagulation (clotting) tests. **Osteonecrosis of the jaw (ONJ):** exposed, necrotic bone in the maxillofacial region for at least 8 weeks in patients receiving an antiresorptive medication. **Osteoradionecrosis (ORNJ):** similar to osteonecrosis of the jaw but caused by radiation to the head and neck. **Petechia:** small, pinpoint collections of blood under the skin or mucous membrane. **Prosthetic joint infection (PJI):** also known as periprosthetic infection, is an infection involving the joint prosthesis and surrounding tissue.[^5^](https://www.dentalcare.com/en-us/ce-courses/ce628/references#5) **Valvulopathy:** a disorder of valve function causing a variety of cardiac disorders, such as arrhythmia, pulmonary hypertension, heart failure, and cardiogenic shock.[^1^](https://www.dentalcare.com/en-us/ce-courses/ce628/references#1) **Thrombocytopenia:** medical term for a low blood platelet count. **Antibiotic Prophylaxis** **[Bacteremia]** This can occur from any manipulation of the gingiva or periapical tissue or perforating the oral mucosa. Examples: Probing; SRP; placing ortho bands subgingivally. If a procedure can cause bacteremia (orally or systemically), and the patient is more at risk for infections, they would require antibiotic prophylaxis. A table with text and words Description automatically generated with medium confidence *Total Joint Replacements* - Immunocompromised/Immunosuppressed - Have Comorbidities (2+ concurrent diseases) *Infective Endocarditis* 1. Prosthetic Heart Valve - Transcatheter-Implanted Prostheses - Homograft 2. Prosthetic Material in Cardiac Valve Repair - Annuloplasty Rings & Chords 3. Previous Hx of IE 4. Cardiac Transplant Pts w/ Valve Regurgitation from Damaged Valves 5. Congenital Heart Disease (CHD) - Unrepaired Cyanotic CHD - Palliative Shunts & Conduits - Repaired CHD Defect - Residual Shunts or Defects - Valvular Regurgitation on, or next to, Prosthetic Patch/Device - Had the repair done in the last 6 months. ![](media/image2.png) A white box with black text Description automatically generated [Amoxicillin is 1^st^ Line Therapy] It effectively kills all 3 micro-organism types which cause IE. - Staphylococcus aureus (on skin) - Streptococci viridans (alpha-hemolytic; in mouth/pharynx) - Enterococci (in GI) If the dental procedure lasts longer than 6 hrs, another dose of Amoxicillin needs to be given. If another antibiotic is being taken by the patient for another reason, or they need more antibiotics \ - This can be done at home by a catheter surgically implanted into the abdomen. - It is performed 4x daily. - It can cause patients to have GERD, so they sit in a semi-supine position. **[Dental Treatment Modification for those with Renal Disease]** A medical consult is recommended to establish disease control & determine the POSSIBLE need for antibiotic prophylaxis due to a hemodialysis shunt. It is best to schedule appointments on the day after their dialysis treatment because they will be rested, and the heparin effects are no longer in the body. Patients can still have nitrous oxide and a local anesthetic w/ a vasoconstrictor. Frequent recalls should be implemented to keep infection under control or to catch them early. **Bleeding Disorders** These people may develop spontaneous gingival bleeding. Therefore, they need good oral hygiene instructions to prevent infections and reduce bleeding. **[Platelet Disorders]** Normal platelet counts are 140,000-400,000. ***Thrombocytopenia*** Low blood platelet count (starting at 50,000). These levels are too low to have treatment from a dental provider. Treatment: **[Anticoagulant Disorders]** ***Hemophilia*** This is a rare, inherited, bleeding disorder where the blood cannot clot normally. Symptoms: Increased/Prolonged Bleeding **[Anemia]** This is a deficiency of hemoglobin where there are too few RBCs. These patients have an increased risk of infection & poor wound healing. Oral Signs of Anemia: Pallor in the oral mucosa. Loss of papilla from the tongue (sore & red). Angular Cheilitis ***Iron Deficiency Anemia*** These people have low iron levels. ***Pernicious Anemia*** These people have low B12 levels due to a lack of intrinsic factor. ***Sickle Cell Anemia*** These people have sickle shaped RBCs. Most common in African Americans. Limit local anesthesia w. epi. **[Drug-Induced Clotting Abnormalities]** ***Anticoagulants*** If the patient is taking blood thinners (anticoagulant), you need to ask them what their PT (Prothrombin Time)/INR is (International Normalizing Ratio). You NEVER take them off their anticoagulant without consulting a doctor. Examples of Anticoagulants Warfarin/Coumadin You can treat patients with an INR of 2-3 (lower \#s are better). INRs 3.5 or more need a medical consult before treatment. Prothrombin Time should be less than 20 sec. Examples of Direct Anticoagulants Apixaban Rivaroxaban It is said that these do not need any alteration before dental procedures. ***Antiplatelets*** If a patient is taking an antiplatelet, you need to ask them what their platelet count and PFA-100 is instead of INR. Examples of Antiplatelet Medications Clopidogrel (Plavix) Aspirin Ibuprofen NSAIDS **Immunocompromised Patients** Certain conditions put people at a greater risk for being immunocompromised. They are discussed below. **[Hepatitis]** This is inflammation of the liver from a viral infection. There are 5 types A-E, but A-C are the most common. A: This is transmitted via fecal-oral route but there is a vaccine to prevent. It does NOT result in chronic infection, but it can result in liver failure. B: This is transmitted via blood, saliva, semen, & vaginal fluid. There is also a vaccine to prevent this type. C: This is the MOST FREQUENTLY TRANSMITTED via IV drug use. \50% develop a chronic infection which can lead to liver failure or cancer. The scary things about this one is there is NO vaccine to prevent. Dental Considerations: Limit local anesthetic w. vasoconstrictor to 2-3 cartridges. **[HIV]** HIV stands for human immunodeficiency virus. It is found in bodily fluids and is transmitted through blood, semen, vaginal secretions, and breastmilk. When CD4+ T-Lymphocyte counts get below 200, HIV patients are considered to have AIDS (Acquired Immunodeficiency Syndrome). The lymphocytes are killed, so their \#'s decrease while their viral load increases. Dental Considerations: Medical consult is needed if current lab reports are not available to determine current CD4+ counts which is correlated to the level of immunosuppression. **[Cancer]** Oral complications are common after patients receive chemotherapy or radiation for cancer treatment. ***Oral Mucositis*** This is inflammation and ulceration of the mouth. Salt & Sodium Bicarbonate Mouth Rinse. ***Fungal Infections*** Candidiasis ***Xerostomia*** This is a result of salivary gland dysfunction. Dental Considerations: Xylimelts or Xylitol Based Gum Suck Ice Chips ***Radiation Caries*** Dental Considerations for Cancer Patients in General: If a patient is taking bisphosphonates, they have an increased risk of developing Osteonecrosis of the Jaw (ONJ). **Endocrine Disorders** **[Thyroid Disorders]** ***Hyperthyroidism*** This is when there are elevated levels of T3 & 4 but low/undetectable TSH levels. *Graves' Disease* This is an autoimmune disease. ***Hypothyroidism*** Decreased levels of T3 & 4 but increased TSH levels. Symptoms = cold intolerance; fatigue; weight gain; diffuse goiter. *Hashimoto's Thyroiditis* This is also an autoimmune disease. This has the same dental considerations as Hyperthyroidism. **[Adrenal Gland Disorders]** ***Primary Adrenalinsuffiency*** *Addison's Disease* ***Secondary Adrenalinsufficiency*** Treatment Synthetic Glucocorticoids These treat: Adrenal Insufficiency Rheumatoid Arthritis Systemic Lupus Asthma Hepatitis Organ Transplantation Immunosuppression Therapy Joint Replacement Immunosuppressive Therapy These include: Cortisone 25mg Hydrocortisone (Cortisol) 20mg Prednisone 5mg Dental Considerations: Nitrous can be used. It can even be helpful for minimizing stress and reducing the demand for cortisol. Local anesthesia with vasoconstrictor is fine and encouraged to achieve adequate anesthesia and reduce the pt's stress levels. A med consult is only needed if they are uncontrolled and have an acute infection. You can also use a med consult to ask about supplemental steroid use for surgical procedures of infections. **Questions to Go Through** 1. **Which of the following statements about antibiotic resistance is correct?** A.

Emphysema Chronic Bronchitis Asthma Signs of COPD: Coughing w/ large amounts of mucous. Nightly coughing or early in the morning. -- Asthma Wheezing Chest Tightness Shortness of Breath Physical activity makes it worse. Frequent Respiratory Infections If Severe: Lower Extremity Edema Weight Loss Decreased Muscle Endurance Blue Lips or Fingernails Tachycardia Decreased Alertness Causes: Long term exposure to lung irritants (air pollution; chemical fumes; dust; secondhand smoke). Genetics: Alpha-1-Antitrypsin Deficiency Respiratory Infections Allergies can be a risk factor for Asthma. Dental Management of Pts with COPD: Asthma medications reduce the amount and quality of saliva, increase the risk of mouth breathing, dental caries, dental erosion, periodontal disease, and oral candidiasis. GERD is common in those with Asthma which can result in enamel erosion. Chronic smokers may have Leukoplakia, Erythroplakia, or Carcinoma. COPD increases the risk of arthritis & depression. Oral conditions could also affect those with COPD. **Diabetes** This is a chronic metabolic disease that affects how the body turns food into energy which causes too much sugar to accumulate in the blood (high blood glucose). ***Type I*** This is an autoimmune disease where the pancreas does not make enough insulin. This type can cause nausea, vomiting, and stomach pain. ***Type 2*** Signs of Diabetes: Peeing a lot...especially at night. Extreme Hunger & Thirst Acetone on Breath Unexplained Weight Loss Blurry Vision Numb/Tingling Hands/Feet Tiredness Dry Skin Sores which don't heal/heal slowly. Increased \# of Infections Long term control of blood glucose is evaluated using HbA1c readings which tells us the amount of glycosylation of hemoglobin A in RBCs. Measurements under 7% indicate the patient's diabetes is well-controlled. 6.5% indicates the patient is a diabetic. Dental Considerations: Uncontrolled diabetes can lead to hypo or hyper-glycemia. Hypoglycemia can lead to the patient becoming unconscious, going into a coma, or dying. Always be mindful of the pt's blood sugar levels because dental procedures can cause stress which increases the likelihood a pt's glucose levels would rise (hyperglycemia). Epinephrine is fine but can sometimes increase glucose levels. Morning appointments are better because the pt's are less likely to have hypoglycemia. **Questions Over These Topics + Heart Diseases & Stroke** 1\. **Which of the following factors does NOT contribute to developing chronic diseases?** A.
