✅ What Is the Temporomandibular Joint (TMJ)?
The temporomandibular joint (TMJ) connects the lower jaw (mandible) to the skull. It works like a hinge and a sliding joint at the same time, allowing us to talk, chew, swallow, and yawn. Inside the joint, a small cartilage disc helps movements stay smooth and quiet.
When this system loses coordination or becomes irritated, joint sounds may appear.

📌 Recommended Article :

Dental Article 🔽 Night Guards: Do They Really Help with Bruxism? ... Optimal management often requires a multidisciplinary approach, combining occlusal therapy with behavioral strategies, stress management, and, when indicated, pharmacological or adjunctive therapies.

✅ Main Causes of Jaw Clicking
Jaw noises usually occur due to changes in joint mechanics, muscle tension, or disc position. The most common causes include:

▪️ Disc displacement
▪️ Joint inflammation
▪️ Muscle overload or tension
▪️ Degenerative joint changes
▪️ Joint hypermobility
Not all clicking is painful or dangerous, but persistent noise, pain, or limited movement should be evaluated.

Principles for the Management of Odontogenic Infections: An Evidence-Based Clinical Approach

Odontogenic infections remain a significant clinical challenge in dental practice due to their potential for rapid progression and life-threatening complications. These infections originate from dental or periodontal tissues and may spread to adjacent fascial spaces if not managed appropriately.

📌 Recommended Article :

Dental Article 🔽 Appropriate Antibiotic Use in Pediatric Odontogenic Infections: Guidelines for Dentists and Dental Students ... This article provides evidence-based, clinically practical guidance for dentists and dental students on the appropriate use of antibiotics in pediatric odontogenic infections.

The cornerstone of effective management lies in the early recognition, accurate diagnosis, and adherence to well-established treatment principles.

Advertisement

The management framework proposed by Peterson et al. continues to be widely accepted and serves as a systematic, evidence-based protocol for controlling odontogenic infections while minimizing morbidity and mortality.

✅ Conceptual Framework for the Management of Odontogenic Infections
Although Peterson et al. originally proposed an eight-step protocol for the management of odontogenic infections, Velasco and Soto later introduced a simplified and clinically oriented adaptation. In their article Principles for the Management of Odontogenic Infections with Different Levels of Complexity, the authors condensed the original framework into seven core principles, maintaining diagnostic rigor and therapeutic effectiveness while improving clinical applicability.
This simplified model emphasizes sound clinical decision-making, prioritization of surgical intervention, and patient-centered care, making it particularly valuable in routine dental practice and academic training. Accordingly, the present article adopts the seven-step protocol proposed by Velasco and Soto, which remains firmly grounded in Peterson’s original principles while offering a more streamlined and practical approach for managing odontogenic infections across varying levels of severity.

Odontogenic facial cellulitis in pediatric patients represents a potentially serious complication of untreated dental infections, characterized by the rapid spread of bacteria through facial and cervical soft tissues.

I. Determining the Etiology and Severity of the Infection
The first and most critical step is identifying the source and extent of the infection. Odontogenic infections typically arise from:

▪️ Pulpal necrosis
▪️ Periapical pathology
▪️ Periodontal infections
▪️ Pericoronal infections
Severity assessment must include evaluation of pain, swelling, fever, trismus, dysphagia, airway compromise, and fascial space involvement. Severe or rapidly spreading infections require urgent intervention due to the risk of systemic involvement.

II. Evaluation of Medical History and Immune Status
A comprehensive medical history is essential to identify conditions that may alter disease progression or treatment response. Patients with diabetes mellitus, immunosuppression, malignancies, or chronic systemic diseases are at higher risk for complications.
Understanding the patient’s immune status allows clinicians to anticipate aggressive disease behavior and tailor treatment accordingly.

Dental Article 🔽 Dental Abscesses in Primary Teeth: Evidence-Based Management in 2025 ... Dental abscesses in primary dentition represent one of the most common pediatric dental emergencies. They can lead to severe pain, swelling, and systemic involvement if not treated promptly.

III. Decision on the Appropriate Setting of Care
The decision to manage the infection on an outpatient or inpatient basis depends on:

▪️ Severity and anatomical spread
▪️ Presence of systemic signs
▪️ Airway involvement
▪️ Patient’s general health status
Hospitalization is mandatory when there is airway compromise, systemic toxicity, dehydration, or involvement of deep cervical or fascial spaces.

IV. Surgical Management
Surgical intervention is the primary treatment modality for odontogenic infections. This includes:
▪️ Elimination of the infection source (tooth extraction or endodontic treatment)
▪️ Incision and drainage of abscesses
▪️ Adequate debridement of necrotic tissue
Antibiotics alone are insufficient without proper surgical management, especially in established abscesses.

📌 Recommended Article :

Dental Article 🔽 Dental Abscesses: Types, Characteristics, Treatments, and Etiological Classification ... Understanding the types of dental abscesses, their etiological classification, and appropriate treatment strategies is essential for accurate diagnosis and effective clinical management.

V. Medical and Nutritional Support
Supportive care plays a crucial role in recovery. Patients with severe infections often require:

▪️ Hydration therapy
▪️ Pain control
▪️ Nutritional support to maintain immune function
Adequate caloric intake and fluid balance are essential, particularly in patients with fever, dysphagia, or prolonged infection.

VI. Appropriate Selection and Prescription of Antibiotics
Antibiotic therapy should be adjunctive, not a substitute for surgical treatment. Selection must be based on:

▪️ Likely causative microorganisms
▪️ Local antimicrobial resistance patterns
▪️ Patient allergies and systemic condition
Empirical therapy often targets aerobic and anaerobic oral flora, with adjustments made based on clinical response. Rational antibiotic use is critical to prevent antimicrobial resistance.

VII. Periodic Patient Evaluation
Continuous monitoring is essential to assess treatment effectiveness. Follow-up should include evaluation of:

▪️ Reduction in swelling and pain
▪️ Improvement in systemic symptoms
▪️ Restoration of function
Failure to improve within 48–72 hours necessitates reassessment of diagnosis, surgical adequacy, and antimicrobial therapy.
