    Study Notes

    Apical & Periodontal Abscess

    • Key topic of presentation is apical and periodontal abscesses, focusing on their management
    • Aims to outline aetiology, classification, clinical presentation, diagnosis and management options
    • Differentiates between apical and periodontal abscesses

    Learning Outcomes

    • Students should be able to identify the causes (aetiology) of apical and periodontal abscesses
    • Differentiate between the clinical presentations of the two conditions
    • Determine appropriate management strategies for both types of abscess

    Aetiology & Classification of Apical & Periodontal Abscess

    • Apical abscess: inflammatory reaction to pulpal infection and necrosis, characterized by rapid onset, pain, tenderness to pressure, pus formation, and swelling
    • Periodontal abscess: localized accumulation of pus within the gingival wall of the periodontal pocket, leading to significant tissue breakdown
    • Pulp necrosis is a key factor for apical abscess, resulting from bacterial invasion, trauma (impact, fracture, restorative procedures, occlusion) or bacterial invasion from accessory canals

    Dental Abscess

    • Localized collection of pus associated with the tooth. An image illustrating a tooth with an abscess is included as visual aid

    Inflammatory Response

    • The body's response to infection involves neutrophil recruitment, clotting factors, and abscess formation
    • Outcomes of infection interaction with tissues (osteoblast and osteoclast) are altered by the infection
    • The objective of the response is to contain the infection and initiate the healing process

    Definitions

    • Apical Abscess: inflammatory reaction to pulpal infection and necrosis, characterized by rapid onset, pain, tenderness, pus formation, and swelling
    • Periodontal Abscess: localized accumulation of pus within the gingival wall of the periodontal pocket resulting in a significant tissue breakdown

    Terminology

    • Apical Abscess

    • Periapical Abscess

    • Dento-alveolar Abscess

    • Apical Periodontitis

    • Alveolar Abscess

    • Radiographs are crucial to pinpoint location and extent of damage/infection.

    Aetiology of Apical Abscess

    • Bacteria from carious lesions
    • Trauma (impact/fracture, restorative procedures, occlusion)
    • Bacterial invasion from lateral/accessory canals

    Acute Periodontal Lesions

    • Includes periodontal abscesses and necrotizing periodontal diseases, and endo-periodontal lesions
    • Aetiology is a combination of virus infection, surgeries and other abscesses

    Classification of Periodontal Abscesses

    • Acute exacerbation is a category related to untreated periodontitis which may be non-responsive to periodontal therapy
    • Other categories are related to supportive periodontal therapy, post-scaling, post-surgery, post-medication, systemic antimicrobials, and other drug treatment options (e.g. nifedipine)

    Impaction

    • Harmful habits like nail-biting, clenching, or specific orthodontic interventions can cause impaction
    • Gingival overgrowth or alterations of tooth structure can also lead to impaction

    Microbiology

    • A mix of facultative and strict anaerobic gram-negative bacteria are prevalent within an abscess
    • Viridans Streptococci, Porphyromonas gingivalis, Prevotella spp., Fusobacterium nucleatum, Tannerella forsythia, and other species are likely present

    Clinical Presentation

    • Includes extra-oral (facial swelling, fever, regional lymphadenopathy) and intra-oral characteristics (visual description, tenderness to percussion and palpation, fluctuance or pus drainage)

    Diagnosis

    • Diagnosis incorporates a comprehensive approach combining history, clinical examination, special tests, and radiological examinations

    History/Symptoms

    • Assess the presence of pain, tenderness to the touch, swelling, mobility of the tooth, and relevant past medical/dental history

    Extra-Oral

    • Assess for facial swelling, elevated body temperature, and lymphadenopathy

    Intra-Oral

    • Assess for visual description of swelling, tenderness palpation and percussion, pus formation
    • Assess of bleeding, suppuration, fistula/sinus presence, pocket depth, and if deep caries or poor restorations or seal are present

    Special Tests

    • Assess thermal and electric pulp tests, considering factors like multi-rooted teeth that influence these tests

    Radiographic Views

    • Periapical radiographs are vital for identifying apical abscesses—bitewing used for adults, while other X-Ray techniques may be used for pediatric patients.

    Management Options

    • Analgesics, warm salt rinses, draining the abscess, antibiotic treatment, periodontal/endodontic treatment, and extraction are among the management options.
    • Antibiotics are generally indicated only if infection or systemic involvement is evident and if spread is confirmed. Otherwise definitive care plan usually involves arranging a follow up with a dentist before deciding on a treatment approach.
