What is periodontology?

Periodontology is a specialized branch of dentistry that deals with the prevention, diagnosis and treatment of diseases of the supporting tissues of the teeth, known as the periodontium. The periodontium is composed of the gums, alveolar bone, periodontal ligaments and dental cementum, all of which have the role of fixing the tooth in the alveolus and ensuring its stability. Periodontitis is crucial not only for oral health, but also for general health, as untreated periodontal diseases can have serious implications, including tooth loss and systemic problems.

What does periodontology do?

Periodontology focuses primarily on the prevention and treatment of gum disease and periodontal disease. These are inflammatory conditions that affect the tissues around the teeth and are usually caused by the accumulation of bacterial plaque on the surface of the teeth and below the gum line.

  • ● Gingivitis: This is the early stage of periodontal disease and is manifested by inflammation of the gums. Gingivitis is reversible if treated in time with proper oral hygiene and professional prophylactic treatments.
  • ● Periodontitis: If gingivitis is not treated, the inflammation extends to the ligaments and bone that support the teeth, leading to periodontitis. At this stage, the destruction of the supporting tissues is irreversible, and treatments are more complex. Periodontitis can lead to tooth loss if not managed properly.

In addition to treating gum and periodontal diseases, periodontology also includes surgical procedures to regenerate lost tissues, as well as dental implants to replace lost teeth.

Causes and symptoms of periodontal disease and diagnosis in periodontology

Periodontal disease has several causes, but the main one is the accumulation of bacterial plaque. Bacterial plaque is a thin film of bacteria and food debris that constantly forms on the teeth and gums. If it is not removed regularly by brushing and flossing, it turns into tartar, which is much more difficult to remove and causes inflammation of the gums. Here are the main causes of periodontal disease:

  1. 1. Plaque and tartar: Plaque is the main factor responsible for gum disease. When the bacteria in plaque interact with sugars in food, they produce acids that attack tooth enamel and irritate gum tissue. Tartar forms when plaque is not removed and mineralizes, causing an inflammatory reaction in the gums.
  2. 2. Poor oral hygiene: Poor oral hygiene, characterized by insufficient brushing and lack of flossing, allows plaque to accumulate on the teeth and gums. Unhealthy habits, such as frequent consumption of sugary foods or lack of regular visits to the dentist, also increase the risk of periodontal disease.
  3. 3. Smoking: Smoking is one of the greatest risk factors for developing periodontitis. Smoking affects blood circulation to the gums, weakens the immune system response, and makes the body less able to fight bacterial infections in the oral cavity.
  4. 4. Diabetes: People with diabetes, especially uncontrolled diabetes, are more susceptible to periodontal disease because high blood sugar levels affect the body's ability to fight infections. Periodontal infections can also make it more difficult for people with diabetes to control their blood sugar.
  5. 5. Genetic factors: Studies show that some people have a genetic predisposition to developing periodontal disease. In these cases, even with rigorous oral hygiene, the risk of developing gingivitis and periodontitis may be higher than normal.
  6. 6. Stress: Stress affects the immune system, weakening the body's ability to fight infections. Stressed people are also more likely to neglect their oral hygiene, which contributes to the development of periodontal disease.
  7. 7. Hormonal changes: Women are more susceptible to gum disease during certain periods of life, such as pregnancy, puberty, or menopause, due to hormonal fluctuations. Hormones can influence how the gums react to the bacteria in plaque.
  8. 8. Medications: Certain medications, such as antihistamines drugs, antidepressants and high blood pressure medications, can reduce saliva flow, which favors the accumulation of bacterial plaque and the development of gum disease.

Symptoms of periodontal disease

Periodontal disease develops gradually and often does not present painful symptoms in the early stages. Therefore, it is essential that patients pay attention to early signs and consult a dentist at the first symptoms. Here are the main symptoms that may indicate the presence of periodontal disease:

  • 1. Bleeding gums: Gums that bleed while brushing or flossing are one of the most common symptoms of gingivitis. This symptom indicates inflammation of the gums and should be treated as soon as possible to prevent progression to periodontitis.
  • 2. Red, inflamed gums: Gingivitis causes the gums to become swollen and red, and they become tender to the touch. If these symptoms are ignored, the inflammation can spread to the supporting structures of the tooth, causing permanent damage.
  • 3. Gingival recession: In advanced stages of periodontitis, the gums begin to recede from the surface of the teeth, leaving the roots exposed. This not only affects the aesthetics of the smile, but also increases the risk of root decay and tooth sensitivity.
  • 4. Bad breath (halitosis): Another common sign of periodontal disease is persistent bad breath. This is caused by the accumulation of bacteria and food debris below the gum line, as well as infections associated with periodontal disease.
  • 5. Tooth mobility: As periodontitis progresses, the ligaments and bone that support the teeth begin to break down, leading to tooth mobility. In advanced cases, teeth can become so loose that they require extraction.
  • 6. Pus between the teeth and gums: The appearance of pus is a clear sign of a severe periodontal infection. This requires immediate intervention to prevent serious complications, such as periodontal abscess or tooth loss.
  • 7. Bite changes: As the bone and ligaments that support the teeth deteriorate, the teeth may begin to move, leading to bite changes or occlusion problems.

Diagnosis in periodontology

Diagnosis of periodontal disease involves a combination of clinical examinations and radiological investigations to assess the condition of the tissues supporting the teeth. The dentist will use the following methods to make an accurate diagnosis:

  • 1. Clinical examination: The dentist will visually assess the health of the gums, looking for signs of inflammation, redness, bleeding, and gum recession. They will also check for the presence of bacterial plaque and tartar, as well as tooth mobility, which may indicate loss of bone support.
  • 2. Periodontal Probing: This method involves using an instrument called a periodontal probe, which measures the depth of the periodontal pockets (the spaces between the teeth and gums). Normally, these spaces do not exceed 1-3 mm. If the pockets exceed 4 mm, this indicates moderate or advanced periodontitis.
  • 3. Dental X-rays: X-rays are essential to assess the condition of the alveolar bone that supports the teeth. In the case of periodontal disease, X-rays can show bone loss around the roots of the teeth, confirming the severity of the condition. Bitewing and periapical X-rays are most commonly used to assess the bone and supporting structures.
  • 4. Microbiological tests: In certain cases, the dentist may recommend microbiological tests to identify the type of bacteria causing the periodontal infection. These tests are useful in personalizing treatment, especially for patients who do not respond to standard treatments.
  • 5. Bite examination: Bite changes and tooth displacement can be an indication that periodontitis has progressed and affected the bone support. The dentist will check how the teeth align and interact during chewing.

Once the diagnosis is established, the periodontist will develop a personalized treatment plan, depending on the severity of the disease and the specific needs of the patient.

3. Treatment methods used in periodontology

Periodontal treatments vary depending on the stage of the disease and the severity of the damage to the supporting tissues. The main goal of treatments is to control infection, reduce inflammation, and prevent further tissue and tooth loss. Periodontal treatments can be non-surgical or surgical, depending on the severity of the disease.

Non-surgical treatments

1. Scaling and root planing

This is the first step in the treatment of periodontal disease and consists of removing plaque and tartar from the teeth and below the gum line. Scaling is the procedure by which tartar is removed, while root planing involves smoothing the root surfaces of the teeth to remove bacterial toxins and promote the reattachment of the gums to the teeth.

  • ● Scaling removes tartar deposits from the teeth, thus preventing the accumulation of bacteria that irritate and inflame the gums.
  • ● Root planing smoothes the exposed roots of the teeth, reducing the risk of recurrence of infection and facilitating the reattachment of healthy gum tissue.

These procedures are performed under local anesthesia, and the desired result is to reduce the depth of periodontal pockets and eliminate the bacteria that cause inflammation.

2. Local drug treatment

In cases of moderate or advanced periodontitis, the doctor may recommend the administration of local antibiotics in the form of gels or inserts placed directly into the periodontal pockets. These drugs help eliminate bacteria and reduce infection. Chlorhexidine in the form of mouthwash or gel can also be used to disinfect the area and prevent the bacteria from reappearing.

Surgical treatments

For cases of advanced periodontitis, non-surgical treatments may not be enough, and the periodontist will recommend surgical procedures to save the affected teeth and repair the damage caused by the infection.

1. Flap surgery

Flap surgery is a surgical procedure used to treat deep periodontal pockets that have not responded to conservative treatments. During the procedure, the periodontist makes small incisions in the gums and lifts a flap of tissue to gain direct access to the roots of the tooth and the underlying bone. Tartar and bacteria are removed, and the flap is then repositioned to reduce the size of the pockets.

This procedure helps restore gum tissue health and prevent disease progression.

2. Soft tissue grafts

In cases of severe gum recession, the periodontist may perform a soft tissue graft to cover the exposed roots of the teeth. This procedure involves taking healthy tissue, either from the roof of the mouth (palate) or from a donor, and placing it over the areas affected by gum recession.

Soft tissue grafts not only improve the aesthetic appearance of the gums, but also provide additional protection against root decay and tooth sensitivity.

3. Bone grafts and tissue regeneration procedures

In advanced cases of periodontitis, where the alveolar bone has been destroyed, bone grafts may be used to stimulate bone regeneration. The grafts may be taken from the patient's own bone, from a donor, or may be synthetic materials. The goal is to rebuild the bone that has been lost due to periodontal infection, providing support for the remaining teeth.

In addition to bone grafts, periodontists can use guided tissue regeneration (GTR) techniques, which involve placing special membranes between the bone and the gum tissue. These membranes allow the bone to regenerate without interference from soft tissue, providing a better support structure for the teeth.

4. Coronal lengthening

This is a surgical procedure used when there is an excessive amount of gum tissue covering the tooth. Coronal lengthening is often used for aesthetic purposes or to prepare a tooth for the application of a dental crown or filling. The periodontist removes some of the gum tissue and, if necessary, some of the bone, to expose a larger portion of the tooth.

5. Tooth extractions

In extreme cases, where periodontal disease has advanced significantly and the tooth can no longer be saved, the dentist may recommend tooth extraction. This is the last resort, when regenerative treatments are not possible. After extraction, the patient may be recommended a dental implant or a bridge to replace the lost tooth.

  • ● Metal crowns: They are very durable and are used especially for back teeth, which withstand high chewing forces. The disadvantage is that they are not aesthetic, due to the color visible metal.
  • ● Ceramic crowns: Ceramic crowns are preferred for front teeth because they perfectly match the color and natural shape of the teeth. They are resistant to staining and offer excellent aesthetics, being almost indistinguishable from natural teeth.
  • ● Metal-ceramic crowns: These crowns combine the strength of metal with the aesthetics of ceramic. They are often used for posterior teeth, where both durability and a natural appearance are desired.

Benefits of periodontal treatment

In addition to restoring oral health, periodontal treatment offers a number of significant benefits for patients:

  • 1. Prevention of tooth loss: Properly administered periodontal treatment can stop the progression of the disease and prevent tooth loss. This has a major impact on chewing function and the aesthetic appearance of the smile.
  • 2. Improve overall health: There is a clear link between oral health and overall health. Periodontal disease has been associated with an increased risk of cardiovascular disease, diabetes, and respiratory conditions. Periodontal treatments reduce chronic inflammation in the body and contribute to better overall health.
  • 3. Improve smile aesthetics: Gingival recession and loss of supporting tissues can affect the aesthetic appearance of the smile. Through soft tissue grafts and regeneration procedures, patients can achieve a more beautiful and healthier smile.
  • 4. Preventing Pain and Discomfort: Advanced periodontal disease can cause pain and discomfort, and appropriate treatments help to relieve these symptoms and restore comfort to patients.

Tips for Preventing Periodontal Disease

Prevention is essential for maintaining healthy gums and teeth. Here are some tips to prevent the onset and progression of periodontal disease:

  • 1. Proper oral hygiene: Brushing your teeth at least twice a day and flossing are essential for removing plaque and preventing tartar formation.
  • 2. Regular visits to the dentist: Regular check-ups with the dentist allow for early detection of gum problems and the application of appropriate treatments before the disease progresses.
  • 3. Quitting smoking: Smoking is one of the biggest risk factors for developing periodontal disease. Quitting smoking can significantly reduce the risk of developing periodontitis and improve treatment outcomes.
  • 4. A balanced diet: A healthy diet, rich in vitamins and minerals, supports gum health and helps prevent inflammation. Avoiding foods high in sugar and refined carbohydrates reduces the risk of plaque buildup.
  • 5. Stress management: Stress affects the immune system and can increase susceptibility to infections, including periodontal disease. Relaxation techniques and stress management can have a positive impact on oral health.

By adopting effective preventive measures and regularly consulting a periodontist, patients can prevent and control periodontal diseases, thus maintaining long-term oral health.

Periodontology is an essential branch of dentistry, dedicated to maintaining and restoring the health of the supporting tissues of the teeth. Periodontal diseases, if not treated in time, can lead to severe complications, including tooth loss. However, with modern treatment methods and proper oral hygiene, these conditions can be effectively managed, allowing patients to enjoy a healthy smile and improved overall health.

Periodontology is not only about treating gum disease, but also about prevention, education and maintaining optimal oral health. A close collaboration between the patient and the periodontist is the key to successful long-term management of these conditions.
