Necrotizing gingivitis: symptoms, causes, diagnosis, treatment, and prevention of complications

Necrotizing gingivitis is an acute infectious and inflammatory lesion of the gums, in which pain, bleeding, and areas of necrosis quickly appear, most often on the interdental gingival papillae.

Ulcerative periodontitis: symptoms, diagnosis, treatment

The term "ulcerative periodontitis" in modern dentistry most often corresponds to the old name necrotizing ulcerative periodontitis.

Surgical treatment of periodontitis: when surgery is needed and what methods are used

Surgical treatment of periodontitis is a group of operations that are used not instead of basic therapy, but after it, if inflammation and deep periodontal pockets persist.

Differential diagnosis of periodontitis: signs, errors and examination algorithm

Differential diagnosis of periodontitis is not just a matter of clarifying the disease's name, but a way to understand which tissues are affected, where the inflammation is coming from, and what treatment is actually needed.

Hypertrophic periodontitis: causes of gum overgrowth, diagnosis and treatment

The term "hypertrophic periodontitis" is often used in everyday speech, but in the modern international periodontal classification it is not an independent standard diagnosis.

Catarrhal periodontitis: symptoms, diagnosis, treatment, and disease codes

The term "catarrhal periodontitis" is often found in everyday speech and old dental descriptions, but in the modern international classification of periodontal diseases it is not an accurate independent diagnosis.

Periodontal abscess: symptoms, causes, diagnosis, treatment and risks

A periodontal abscess is an acute purulent inflammation of the periodontal tissues, that is, the tissues that surround and support the tooth.

Papillon-Lefevre Syndrome: Causes, Symptoms, Diagnosis, and Treatment

Papillon-Lefevre syndrome is a rare hereditary disease from the group of genodermatoses, which combines two main symptoms: thickening of the skin on the palms and soles, that is, palmoplantar keratoderma, and severe early periodontitis with rapid destruction of tissue around the teeth.

Suppurative periodontitis: symptoms, treatment, and when to see a doctor

In strict modern dental terminology, "suppurative periodontitis" is not always a separate, independent diagnosis. More often, it refers to one of three conditions: periodontitis with pus discharge from the periodontal pocket, periodontal abscess, or necrotizing periodontal disease.

Periodontitis stages: risk of progression and prognosis for teeth

In everyday speech, people often say “stage 1 periodontitis,” “stage 2 periodontitis,” or “severe periodontitis,” but modern professional classification uses a more precise system: stages from 1 to 4 and risk grades A, B, C.
