K05.313 Chronic periodontitis, localized, severe

Name of the Condition

• Chronic Periodontitis, Localized, Severe

Summary

Chronic periodontitis is a progressive inflammatory condition affecting the tissues that support and anchor the teeth. In its localized, severe form, it involves significant gum inflammation and extensive damage in specific areas of the mouth, leading to substantial bone loss and an increased risk of tooth loss if untreated.

Causes

Chronic periodontitis is primarily caused by the accumulation of plaque—a sticky, bacteria-laden film that forms on teeth. Poor oral hygiene practices facilitate excessive plaque buildup, which can progress into periodontitis.

Risk Factors

• Poor oral hygiene
• Smoking or tobacco use
• Genetic predisposition
• Diabetes and other systemic health conditions
• Certain medications that reduce saliva flow
• Stress and hormonal changes
• Age, particularly in older adults

Symptoms

• Red, swollen, or tender gums
• Bleeding during brushing or flossing
• Gum recession, resulting in longer-looking teeth
• Persistent bad breath or a bad taste in the mouth
• Loose or shifting teeth
• Formation of deep pockets between the teeth and gums

Diagnosis

Diagnosis involves a clinical examination of the gums, measuring the depth of periodontal pockets with a probe, and dental X-rays to assess bone loss. A review of medical history may also be conducted to identify contributing factors.

Treatment Options

Treatment typically includes professional dental cleaning to remove plaque and tartar, scaling and root planing to clean deep pockets, and antibiotics to control infection. In severe cases, surgical procedures such as flap surgery or bone grafts may be necessary to restore damaged tissues.

Prognosis and Follow-Up

With proper treatment and consistent oral hygiene, the progression of the disease can be slowed or halted. Regular follow-up appointments are essential to monitor gum health and prevent recurrence. Severe cases may require ongoing maintenance to preserve remaining teeth.

Complications

Untreated severe chronic periodontitis can lead to tooth loss, gum abscesses, and systemic inflammation that may affect overall health. It may also increase the risk of cardiovascular disease and other systemic conditions.

Lifestyle & Prevention

• Maintain good oral hygiene with regular brushing and flossing
• Quit smoking or avoid tobacco use
• Manage systemic conditions like diabetes
• Use antimicrobial mouth rinses as recommended
• Attend regular dental check-ups and cleanings

When to Seek Professional Help

Seek dental care if you experience persistent gum bleeding, pain, swelling, loose teeth, or bad breath. Early intervention can prevent further damage and improve outcomes.

Tips for Medical Coders

Document the severity and localization of the condition clearly in the medical record. Ensure clinical notes specify the extent of bone loss and pocket depth measurements to support the diagnosis of severe localized chronic periodontitis.
