There are many risk factors that increase the likelihood of periodontal disease development, as well as increasing the severity and speed at which it may occur. Among the most common are:
- Smoking
- Diabetes
- Stress
- Medication
- Poor oral hygiene
- Faulty dentistry
- Hormonal variations
- Immunocompromise
- Connective tissue diseases
- Previous history of active perio disease
The individual risk factors have unique mechanisms of action; however, all operate in one of two ways; increasing biofilm levels or impairing the body’s ability to respond to the bacterial challenge. In some cases both mechanisms are operating.
Increased biofilm levels are caused by high carbohydrate intake (nutrition), poor oral hygiene, and faulty dentistry. Impairing the body’s ability to respond adequately to the level of bacteria is caused by hereditary reduction of immune system function, diabetes, stress, xerostomia from medications, hormonal variations such as those that occur during puberty, pregnancy, menopause and oral contraceptive use and in immunocompromised patients.
Dental professionals are needed to identify and modify these risk factors for periodontal disease. For example, home care instructions are an attempt to modify the contribution of poor oral hygiene to the development of perio disease. Smoking cessation and dietary counseling are also constitute risk factor modification.
All risk factors are not created equal. Diabetes and smoking are the biggest risk factors for gum disease development, increased severity and the speed at which it occurs. The #1 systemic condition that increases susceptibility to perio disease is diabetes. Multiple risk factors do not increase the risk in an additive manner, but rather in an exponential manner. A patient with 3 risk factors such as high stress level, poor oral hygiene and faulty dental work is not 3 times more likely to develop gum disease than a patient without these risk factors, they are approximately 27 times more likely for gum disease to occur or worsen rapidly. On the other side of the coin, when the dentists and hygienists provide perio treatment and behavior modification, they also reduce the risks for gum disease in an exponential manner as well. Eliminating or reducing as many risks as possible will improve disease prevention and treatment outcomes.
Identifying and modifying risk factors prior to and during perio therapy is critical to successful treatment outcomes, long term periodontal health and enhanced patient care. Risk factor reduction can take many forms including; smoking cessation programs, dietary counseling, home care instructions, correcting faulty restorations and encouraging compliance for poorly controlled diabetic individuals. Biofilm control is critical and many recommendations are warranted such as powerbrush usage, interdental biofilm removal devices, antimicrobial mouthrinses and more frequent recare appointments.
