What are Root Caries?

Root caries, also known as root cavities or root decay, refer to a type of tooth decay that occurs on the root surface of teeth [3]. This condition is more prevalent in older adults due to factors such as gum recession and exposure of root surfaces [10].

Characteristics of Root Caries

Root caries are characterized by discolored, softened, and ill-defined lesions on the root surface of teeth [4]. Unlike tooth decay that occurs in the crown (top) part of the tooth, root caries occur where the gums have receded or shrunk, exposing the root surface to bacteria and acid production [5].

Causes and Risk Factors

Root caries are caused by the same factors as other types of tooth decay: acid produced by bacteria metabolizing fermentable carbohydrates results in demineralization of exposed root surfaces [9]. Older adults are more prone to developing root decay due to gum recession, which exposes the roots to bacteria and acid production.

Prevalence and Incidence

Root caries are a common problem, especially among older populations. According to some studies, dental caries is one of the most prevalent diseases in humans, affecting 97% of the population worldwide during their lifetimes [11]. The prevalence of root caries increases with age, making it essential for older adults to maintain good oral hygiene and visit their dentists regularly.

Treatment Options

Root caries can be treated with various methods, including fillings, crowns, or even a root canal if the decay has advanced further into the tooth. Regular dental visits are crucial in preventing and detecting root caries early on [7].

If left untreated, caries may progress to tooth destruction and exodontia.

Common Signs and Symptoms of Root Caries

Root caries, also known as root decay, can be a serious dental issue if left untreated. The symptoms of root caries vary depending on the severity of the condition, but here are some common signs to look out for:

Diagnostic Tests for Root Caries

Root caries, also known as interproximal caries or proximal caries, is a type of dental caries that affects the roots of teeth. Early detection and diagnosis are crucial to prevent further progression of the disease.

Visual-Tactile Examination: The Mainstay of Detection

• Visual-tactile examination is the primary method used by dentists to detect root caries lesions [7][8].
• This approach relies on a combination of visual inspection and tactile sensation to identify lesions [5].

Diagnostic Tests for Root Caries

Several diagnostic tests have been developed to aid in the detection and diagnosis of root caries. These include:

• Radiographs: X-rays can be used to detect interproximal notched radiolucencies, coronal to the bone height, and apical to the cement-enamel junction [10].
• Visual-tactile examination with adjunctive tests: Some studies have investigated the use of visual-tactile examination in combination with other diagnostic tests, such as radiographs or fluorescence-based tests [9].

Limitations and Future Directions

Despite the availability of various diagnostic tests, there are limitations to their accuracy. The certainty of evidence for many of these tests is very low due to a paucity of high-quality studies [3][11]. Further research is needed to develop more accurate and reliable diagnostic tests for root caries.

Risk Assessment Approach

A risk assessment approach can be used to determine a patient's risk of developing root caries. This involves evaluating factors such as oral hygiene, diet, and previous dental history [12].

Treatment Options for Root Caries

Root caries, also known as root surface lesions, are a type of tooth decay that affects the roots of teeth. While restorative treatments like fillings and crowns can be effective in treating coronal caries, the treatment options for root caries are more limited.

Drug Treatments

Several drug treatments have been explored for the management of root caries:

• Silver Diamine Fluoride (SDF): SDF is a topical fluoride agent that has been shown to be effective in preventing and arresting root caries. It contains high concentrations of silver and fluoride ions, which help to prevent bacterial growth and promote remineralization of tooth structure [4][5].
• Sodium Fluoride: Sodium fluoride is another topical fluoride agent that can be used to prevent and arrest root caries. However, its effectiveness may be lower compared to SDF [6].
• Cadexomer Iodine: Cadexomer iodine is a drug that has been used to treat root caries by promoting the formation of a protective barrier on the tooth surface [7].

Other Treatment Options

In addition to drug treatments, other options for managing root caries include:

• Fluoride Treatments: Fluoride treatments can be used to help restore tooth enamel and prevent further decay. In some cases, fluoride treatments may even reverse early stages of cavitation [9].
• Restorative Treatments: While restorative treatments like fillings and crowns are not typically used for root caries, they may be necessary in severe cases where the lesion has progressed to a point where it is affecting the tooth's structure and function.

Conclusion

The treatment options for root caries are limited compared to coronal caries. However, drug treatments like SDF and sodium fluoride can be effective in preventing and arresting root caries. It is essential to consult with a dentist to determine the best course of treatment for individual cases.

Differential Diagnosis of Root Caries

Root caries, also known as root surface caries, can be challenging to diagnose due to its similarity in appearance and symptoms with other dental conditions. To accurately diagnose root caries, it is essential to consider the differential diagnosis from other lesions that may appear on the roots of teeth.

Differential Diagnosis Considerations:

• Developmental Lesions: Hypoplasia, hypomineralization, dental fluorosis, amelogenesis, and dentinogenesis imperfecta can all be mistaken for root caries. These conditions affect the development of teeth and can cause changes in tooth color, texture, or shape.
• External Cervical Root Resorption (ECRR): ECRR is a condition where the root of the tooth resorbs externally, often due to trauma or orthodontic treatment. It can be mistaken for root caries due to its similar appearance on radiographs.
• Recurrent or Secondary Caries: These types of caries occur in teeth that have already been restored and can appear as low-density areas of demineralization adjacent to or under the restoration site.

Key Diagnostic Features:

• Visual Inspection: A thorough visual inspection of the tooth, including its color, contour, surface cavitation, and texture, is essential for diagnosing root caries.
• Radiological Examination: Radiographs can help identify the extent of the lesion and rule out other conditions such as ECRR or recurrent caries.
• Clinical Evaluation: A clinical evaluation by a dentist is necessary to confirm the diagnosis and determine the best course of treatment.
