What is tooth root caries: causes, symptoms and treatment methods


Types of caries localizations

Caries (lat. caries rotting) is a slow and hidden pathological process occurring in the hard tissues of the tooth. It is characterized first by focal demineralization of the enamel, then by the destruction of hard tooth tissues with the appearance of a cavity in the dentin. If left untreated, the tooth is lost or complications arise - pulpitis and periodontitis.

Cervical (circular)


The structure of a tooth is divided into a root, a neck and a crown - the latter is located above the gum. The neck and root are located in the gum and are protected by soft mucosal tissue.

When the carious process begins to destroy the tooth in the area of ​​contact of the crown with the mucous membrane, we can talk about the cervical form of caries.

This category is the most difficult to diagnose and treat. It most often affects the incisors. When biting food with incisors, the food is not only “cut off”, but also gets clogged into the gum pockets, moving towards the gums.

Crown caries

Caries has the ability to affect not only healthy, but also already treated teeth - under a filling or crown. If there is a crown, it is difficult to detect, because the tooth does not have a nerve and pain is not felt. There are no external signs for a long time.

The causes of this type of caries are:

  • defect of the dental crown with the appearance of access to the tooth tissue underneath it
  • poorly treated tooth before prosthetics;
  • gum disease;
  • poor oral hygiene.

The problem is that the process spreads into the deep layers and spreads to the bone structures, as a result of which the tooth is often completely removed. That is why preventive examinations and an orthopantomogram - a panoramic image of the entire jaw - are so important.

Radical caries

Basal and cervical caries are similar. Both incisors and chewing teeth are affected. Destruction begins with the enamel, gradually moving to the nerve in the root canal. When the process touches bone tissue, it threatens with osteomyelitis.

The main reason for the occurrence is a cariogenic situation in the oral cavity, when plaque accumulates especially quickly. The enamel in the root part of the tooth is much thinner and more easily destroyed. It is most often diagnosed between the ages of 30 and 60 years.

Root caries

Root or subgingival caries occurs hidden. It can be with or without a cavity. Along the flow - active, suspended, secondary. It most often affects molars.

Treatment

Treatment tactics are determined by the stage of the carious lesion.

Initial. The structure of hard tissues remains almost unchanged, there are signs of enamel demineralization, and white spots may appear. To stop the destruction of hard tissues, remineralization is performed. Remotherapy will help strengthen the enamel and stop its destruction. Before remotherapy begins, professional hygiene and cleaning of periodontal pockets are performed. Additionally, the doctor may prescribe rinsing with antiseptic solutions.

Dark spot. The dentist removes hard and soft deposits from the surface of the enamel and cleans the periodontal pocket. The affected tissue is removed and a filling is performed. If gum damage has already begun, a focus of inflammation has appeared, additional treatment is carried out: the doctor stops the infection.


Formed cavity. It will be possible to save the tooth provided that the inflammation has been stopped. The doctor removes the affected tissue, strengthens the crown with an inlay, and places an artificial crown.

Root destruction. If the root is destroyed by more than 50%, with severe inflammation or damage to periodontal tissue, the tooth must be removed. After this, implantation and prosthetics or restoration with a dental inlay are performed.

What is the danger of this disease?


Caries is dangerous because there are no symptoms for a number of years. It is detected more often in an advanced stage, when tooth extraction becomes the solution.

Visual diagnosis is difficult because all destructive processes occur inside the tooth. Pronounced plaque or tartar hides any stains on the enamel.

The root is hidden under the gum and external irritants do not affect it until a certain time. On the other hand, the root walls are thin, so they are destroyed quickly and with complications.

Features of the progression of dental caries

In the area of ​​cement, caries can occur in different ways, and on this basis it is classified into 4 types:

  • progressive;
  • rapidly progressive;
  • remission;
  • relapse.

Progressive root caries is characterized by a relatively slow rate of tooth root destruction. With rapidly progressing lesions, the lesion spreads in depth and breadth at high speed. The remission stage is when root cement caries does not progress. Relapse suggests that root caries develops along the edges of a previously placed filling.

Causes of the disease

There are 3 main provoking factors that must act in a complex manner; none of them acts independently:

  1. Cariesogenic microflora - this includes Mutans streptococci, actinomycetes and certain types of lactobacilli. They should dominate the oral cavity. Bacteria produce organic acids from food carbohydrates, which cause demineralization of cement.
  2. Consumption of simple carbohydrates is the most cariogenic. Their breakdown produces glucan, which contributes to the appearance of plaque.
  3. Reduced caries resistance is a deterioration in the resistance of tooth tissue and the body as a whole. This is facilitated by a decrease in calcium content in hard root tissues, bad habits, and lack of saliva.

In addition, the anatomical features of the mouth can also have an effect - a small vestibule, a short frenulum, and bite pathology.

Gum disease, pocket formation

Gum pocket or otherwise periodontitis is a common occurrence in many patients. Many people do not treat it because it does not bother anyone for a long time.

The first manifestation of pathology is bleeding when brushing teeth, although outwardly they may look healthy. Dental pockets or depressions are normal, but their anatomical size should not exceed 3 mm.

Then the pocket is able to self-clean from food debris and epithelial particles. Reservoirs of bacterial accumulations form in deep gaps. This is accompanied by bad breath. Conventional treatment with antibiotics and brushing teeth with toothpaste have no effect.

Causes of periodontitis:

  • insufficient hygiene;
  • poor quality fillings;
  • abnormal position of the dentition, malocclusion;
  • hereditary predisposition;
  • deficiency of vitamins and minerals;
  • immunosuppression.

How to treat cervical caries

Treatment of the disease is carried out by a doctor. In the case of cervical caries, there are a number of reasons for immediately contacting a dentist:

  • Rapid development of complications. In the cervical area, the thickness of hard tissue is minimal, so pulpitis and periodontitis occur more quickly than with other localizations of caries.
  • High probability of crown fracture. Since the lesion tends to cover a large area in the gingival region, due to the softening of hard tissues over a large area, the tooth can break with a slight load.
  • Visible aesthetic defect. Since cervical caries often affects the front teeth, their destruction is noticeable to others, which negatively affects self-esteem, personal life, and career.

Depending on the stage of the pathological process and the damage to certain teeth, treatment methods may vary.

Treatment of cervical caries of chewing teeth

The treatment method for cervical caries depends on the advanced stage of the disease. If in the early stages conservative treatment is sufficient, then in later stages it is impossible to do without drilling the carious cavity (local anesthesia is performed before drilling).

  • Treatment of “chalk spot” and suspended caries. The traditional method is long-term use of products containing fluoride. The dentist applies medications to the affected tooth. At home, the patient uses fluoride-containing toothpastes and rinses to care for his teeth. A modern alternative method is the use of a complex system that includes etching the stain with acid and “sealing” the affected area with a polymer resin (ICON). Treatment is carried out in one visit. Before conservative treatment (by any method), professional tooth cleaning is required.
  • Treatment of enamel caries with the formation of cavity and medium caries. Includes preparation (removal of affected hard tissue), treatment of the cavity with an antiseptic solution, thorough drying and filling. After drying, the filling is ground and polished. The procedures are carried out during one appointment.
  • Treatment of deep caries. It consists of the same stages as for median caries, but after drying the cavity is closed with a therapeutic demineralizing bandage and filling.

In the treatment of cervical caries, they always try to preserve the living pulp (depulpation is performed only when pulpitis develops). Preserving the pulp is important because it is responsible for the production of dentin, the natural restoration of hard tooth tissue. A tooth with preserved pulp lasts longer than a pulpless one.

Treatment of cervical caries of anterior teeth

The principles of treatment of cervical caries of the frontal group of teeth, depending on the spread of the process, do not differ from those with damage to molars and premolars. However, there are some features associated with the fact that the front teeth are visible when talking and smiling. When restoring them, it is important to obtain a good aesthetic effect. To achieve this you can use:

  • Fillings. At the Academy Dent clinic, modern light-curing composite materials are used to fill carious cavities. They imitate tooth enamel well and can be used to cover a defect unnoticed. The seal is made of high-quality material, installed in compliance with all rules, and lasts 10-15 years.
  • Veneers. The installation of plates on the front part of the frontal teeth is indicated for extensive or combined defects (if, in addition to cervical caries, there is a chip or a violation of the position of the tooth). Porcelain and, especially, zirconium veneers compare favorably with composite onlays and fillings in their durability, impeccable aesthetic results, and do not accumulate plaque. The disadvantage of installing any veneers is the preparation of the entire surface of the tooth (including the removal of the entire layer of healthy enamel).

Treatment with folk remedies

It is impossible to cure cervical caries at home. Attempts at self-medication lead to a loss of time for conservative therapy, further tooth destruction and often to its loss. The use of folk remedies is practically not justified.

Lifestyle

If you have learned about the risk group for root caries (older age), this does not mean that you can relax. Caries has many causes and can occur at any age if basic precautions are not followed.

Those at risk include smokers, diabetics, pregnant women and even children. The provoking factors in this case are:

  • smoking and lack of oral hygiene;
  • infrequent brushing of teeth and lack of fluoride;
  • poor nutrition with preference for desserts;
  • frequent stress;
  • alternating hot and cold;
  • structural features of the oral cavity;
  • alcohol abuse - alcohol breaks down into sugars and acids;
  • abuse of coffee and strong tea, which creates an acidic environment in the oral cavity;
  • lack of water intake, and therefore lack of saliva;
  • gum injuries.

Is caries contagious?

Let us recall that dental caries is caused by cariogenic bacteria of the oral cavity - most often certain types of streptococci and actinomycetes. In adults, this microflora is present in everyone without exception. Therefore, you are unlikely to be infected with caries, for example, by kissing. But with children of early childhood the situation is completely different, because... children are born with a sterile oral cavity. In young children, caries is an infectious disease that is caused by infection of the oral cavity of a newborn child by those who care for him.

As a rule, cariogenic microorganisms enter the child’s mouth when the mother (or other persons caring for the child) licks the pacifier, the spoon with which the child is fed, and other objects intended for food. If you decide to try your child’s food with his spoon or kiss your child on the lips, it means you have just passed on your cariogenic bacteria to the child. And the earlier the infection occurred, the higher the intensity of the carious process will be.

Further, children experience rapid growth of cariogenic microflora, which leads to demineralization of tooth enamel. If you pay attention, in young children the carious process affects the teeth circularly - around their necks. Such carious lesions are called bottle caries. Most often, this happens when a child is not only infected with a cariogenic infection, but also when feeding rules are violated at the same time - drinking sweets at night, feeding on demand, etc.

Symptoms of the disease


The process usually occurs without symptoms, but pain may occur when brushing a toothbrush, eating sour, salty, sweet, cold or hot foods.

After eliminating the irritant, everything goes away. The patient can see a doctor if a stain is found on the front surface of the incisors, but often it is hidden under plaque or tartar.

The ongoing carious process gradually reaches the dentin junction, penetrating first into its surface layers and then further. The cavity deepens with bacteria and food debris. There is a smell from the mouth. Irritants cause pain more and more frequently.

With cement caries, teeth become mobile and lose their support, and bleeding gums occur. These are already symptoms of periodontitis. Now, even when chewing food or brushing teeth, severe discomfort occurs.

Digestion begins to suffer. Teeth become hypersensitive to hot or cold.

Next, the process follows the Leus classification:

  1. Active lesion - the edges of the cavity are undermined. The cavity is filled with softened tissues and tends to grow.
  2. Suspended caries - no increase in the affected area is observed. The cavity is clean, the bottom is shiny and smooth, the edges are even and dense.
  3. Secondary caries - occurs under a filling.

Dental cement caries - main clinical manifestations

At an early stage, there may be no symptoms of cement caries at all, making early diagnosis difficult. When a cavity grows, the following symptoms may appear:

  • Discomfort while eating.

With root caries, mobility of the damaged tooth is often observed, which causes discomfort while eating. In addition, minor pain can result from food particles getting into the gum pocket or directly into the carious cavity.

  • External defects.

If caries spreads from the root upward to the cervical area, during the examination the dentist may detect visible changes in the color and structure of the tooth.

  • Pain.

It can appear when the tooth is exposed to cold or hot, or when eating salty, sweet, or sour foods. It is impossible to detect root caries on your own, so you need to visit the dentist twice a year. This is especially important for older people and those with gum disease. In such patients, root caries and deep caries are quite common.

Diagnosis of the disease

The diagnosis is made in stages. Listening to complaints and visual examination make it possible to diagnose caries only in 13% of cases. Classic probing with a sharp probe and inspection with a mirror are informative. This allows you to examine the dentition.

Thermal diagnostics, electroodontometry and x-rays are also performed. If the patient has massive dental plaque, changes in the enamel will not be visible. In this case, professional teeth cleaning is first carried out to remove plaque and stone. All this is possible in a dental clinic.

At the dental clinic


The following types of studies can be performed at the clinic:

  1. Probing with a thin probe with a curved end - it is inserted under the gum, while the doctor has the opportunity to examine the structure of the tooth, its integrity, the presence of irregularities and chips. With rapidly progressing caries, the edges of the cavity are uneven and sharp. In the remission stage, the surface of the pathological focus is shiny, smooth, hard with smooth edges.
  2. Electroodontometry - can determine nerve damage and the depth of inflammation. The pulp reacts differently to the current strength.
  3. Thermal diagnostics - treatment of different areas of the tooth with a stream of water and heated wax. Unpleasant sensations that disappear after removing the irritant indicate caries.
  4. X-ray - a targeted photograph of one tooth or computed tomography. The presence and localization of obvious or hidden inflammation is determined with millimeter precision.
  5. Visiography is a special device - a visiograph scans the received data and transfers it to a computer, where the picture is studied from different angles and in detail, revealing the hidden process of inflammation.

Diagnosis of cement caries: basic and additional methods

Diagnostic methods that help identify dental caries are divided into basic and additional.

The main ones include:

  • patient interview;
  • external visual inspection;
  • probing - determining the depth of the cavity, as well as the density and tenderness of tissues, using a dental probe;
  • percussion (tapping on the tooth).

Additional diagnostic methods are:

  • staining with a special dye to see the affected areas;
  • thermal test - the tooth is irrigated with cold water and the pain reaction is assessed;
  • radiography - helps to detect hidden carious cavities and caries of contact surfaces;
  • electroodontometry - prescribed to determine the condition of the pulp;
  • luminescent method - illumination of teeth with ultraviolet rays, under which tissues affected by caries change their shade.

Root caries itself is most often diagnosed through sequential manipulations:

  • remove deposits from under the gums using ultrasonic and manual instruments;
  • isolate the tooth root from saliva using a special plate;
  • using a probe, assess the condition of the root surface;
  • with the help of x-rays or radiovisiography, even small defects under the gum, in the gingival zone, and carious lesions at any stage are detected;
  • if necessary, confirm the diagnosis of “cemental caries” or differentiate it from pulpitis, thermometry or electrical odontometry is prescribed.

Treatment or removal - what determines the outcome

The doctor makes a decision on treatment or tooth extraction after determining the depth of spread and the area of ​​localization of the inflammatory process. It is mandatory to first carry out professional cleaning using an ultrasonic scaler, an AirFlow water-abrasive device and hand tools.

Initial caries is treated with conservative retherapy. For hard tissue defects, preparation and filling are performed. In severe cases, the tooth is removed.

Treatment of the initial stage of root caries

Conservative retherapy includes:

  • fluoridation of teeth;
  • covering teeth with protective agents
  • training in proper oral hygiene

Different types of caries: WHO classification

Caries is a slowly occurring pathological process in hard dental tissues, which develops under the influence of unfavorable external and internal factors. According to statistics, this disease occurs in more than 90% of people in the world.

Cleaning in dentistry from stone and plaque


1243900247100
Professional teeth cleaning involves removing the accumulation of all pathogenic microflora around the root.

It involves not only removing plaque, but also stones. This elimination of negative factors protects teeth for a long time.

Antiseptic treatment of affected areas

Treatment of root caries involves drilling out all affected areas with a drill and treating the carious cavity with antiseptics and special preparations. A 2% chlorhexidine solution or a gel based on it is used as an antiseptic for the treatment of carious cavities.

Surgical treatment of tooth root caries

Treatment is often complicated by gum disease. Inflammation of soft tissues is an obstacle to the filling procedure or tooth root removal. In such cases, plastic surgery or gum excision is required. Only after this a temporary filling is installed. When the tissue is completely restored, the doctor performs a permanent filling.

During the treatment of dental roots, a rubber dam is used - a latex plate that allows you to isolate one or more teeth from the area that is affected by the carious process.

In general, the procedure is carried out according to the standard algorithm:

  • Application of anesthesia. It is impossible to do without an anesthetic drug during such an operation, because the root and basal areas are most sensitive to external influences.
  • Cleaning the carious cavity from necrotic tissue. The doctor uses a drill to excise damaged areas of the tooth to prepare the cavity for filling.
  • Treating the tooth with an antiseptic solution. If you apply a filling without disinfection, caries will begin to develop underneath it.
  • Filling. Compomer materials that are placed on the root of the tooth are most resistant to the effects of saliva. In addition, they are the most wear-resistant and durable. They contain fluorides, which restore root cement and promote rapid tissue healing.

Tooth root caries develops more often in older people, who, as a rule, have crowns, dentures and other structures in the oral cavity. If they were installed incorrectly or worn out, they must be replaced with new ones. They must exactly match the bite, otherwise the likelihood of recurrent caries increases significantly.

What to do to protect your gums

If the gum is not treated, inflammation will remain and all treatment will become meaningless. The gums are protected by diathermocoagulation and retraction.

Diathermocoagulation

Diathermocoagulation – excision of excess areas of periodontitis with a coagulation knife. The knife immediately cauterizes the bleeding edges. The procedure is performed when there are severe changes in the gums. In such cases, filling is postponed until the soft tissue is completely regenerated.

Retraction

If the condition of the gums is advanced, treatment of caries becomes impossible - the mucous membrane bleeds and interferes with tooth treatment. This gum is excised or a special device is applied to move the gum back. But more often, retraction is performed - lowering the gingival contour or moving apart the overhanging edges of the gums using special hemostatic threads. A temporary filling is placed until complete healing.

Treatment of cement caries: main stages

With root caries, the most difficult task is to gain access to the affected area, especially if the carious lesion is located under the gum. Traditionally, treatment of root caries takes place in several stages:

  • Retraction. First, the dentist artificially exposes the neck of the tooth and part of the root, lowering the gums with special devices.
  • Coagulation of the gums. It is carried out if indicated using laser exposure to gum tissue. The essence of the manipulation is to remove overgrown tissue.
  • Direct treatment of caries. The choice of tactics depends on the degree and depth of the lesion. If caries is in the initial stage of the stain, then remineralizing therapy will be sufficient - restoring the mineral composition of tissues with the help of fluoride preparations. If the doctor reveals more extensive and deep caries with the formation of a cavity, then surgical treatment with preparation and filling will be required.
  • Installation of an inlay or crown if the volume of destroyed tissue is more than 50%.

It is necessary to treat cement caries only in a trusted clinic with a reliable specialist, since violation of treatment technology and the use of low-quality materials can cause secondary caries, provoke the development of infection and inflammation of the gums, and lead to tooth loss.

What preventative measures are there?

To keep your teeth healthy for many years, you need to brush your teeth twice a day, use floss and a tongue scraper. After sweets, you should rinse your mouth and chew gum for 5-10 minutes.

Prevention also includes the removal of tartar. A sufficient amount of saliva is also important, so it is necessary to maintain a water regime.

Like any other pathology, caries is better prevented than treated. Therefore, it is important to visit the dentist twice a year for preventive examinations. People at risk should approach this especially responsibly.

Other

Prevention of root caries

The following preventive measures will help reduce the risk of root caries:

  • Maintaining oral hygiene. In addition to brushing your teeth, it is important to pay increased attention to careful and thorough gum care and high-quality cleaning of periodontal pockets. For this purpose, it is convenient to use irrigators, which with a powerful stream of water remove food debris even from under the gums, massage the gums, helping to strengthen them.
  • Timely treatment of gum disease, as this is one of the main causes of root caries.
  • A rational and balanced diet with a minimum amount of fast carbohydrates and a large amount of vitamins and minerals.
  • Limited consumption of hard foods that can injure the gums.
  • Regular visits to the dental clinic at least twice a year.

Following simple preventive measures will help prevent root caries and maintain dental health even in old age.

Etiology of dental root caries

Despite the large number of theories (more than 400) about the reasons for the development of carious processes, almost all researchers identify a complex of three components. Their simultaneous exposure leads to the development of this disease:

  • Consumption of simple carbohydrates - sucrose, fructose, starch. The first is found in sugar and is the most dangerous. It is from it that streptococci produce: a branched polymer of glucose, which is the initiating factor for demineralization;
  • glucan, which takes part in the formation of dental plaque. In order for pathological processes to start, it is enough for carbohydrates to linger on the surface of the cement for a fairly short time;
  • Cariesogenic microflora - acid-forming streptococci Mutans, Viridans, Sanguis, as well as certain types of lactobacilli capable of producing organic acids from sucrose. Just a few minutes pass after consuming carbohydrates, and the pH in the oral cavity drops from 6 to 4. Cement that is deficient in minerals and salts due to demineralization is particularly vulnerable and permeable to pathogens;
  • Anti-carious microflora (or rather, its reduction). It manifests itself as a deterioration in the ability of dental tissues and the entire body to resist the development of carious processes. The reasons for this phenomenon may lie in a lack of calcium in the hard tissues of the root, a change in the composition of saliva or its own deficiency, or bad habits. The result is a deterioration in the strength properties of dentin tissues and cement, and disruptions in the process of natural cleaning of tooth surfaces with saliva.
  • Very often, treatment of dental root cement caries is required for patients who suffer from dental diseases that are characterized by disruption of the connection between the gum tissue and the tooth surface:

    • Inflammatory damage to periodontal tissue around a dental unit, which is accompanied by destruction of its ligament with the bone jaw tissue (periodontitis);
    • Atrophy in periodontal tissues, which is accompanied by a violation of the integrity of the ligamentous apparatus of the tooth with the alveolar processes of the jaw (periodontal disease);
    • A decrease in the volume of gum tissue towards the upper part of the tooth root, which is accompanied by exposure of its neck (recession).

    The risk of developing the disease increases significantly if the patient does not comply with the rules of oral hygiene and suffers from a decrease in local mucosal immunity.
