° Penicillin allergy: Clindamycin or Azithromycin (with caution).

2. Age and Weight-Based Dosing
Pediatric dosing is weight-dependent and must be calculated accurately to ensure therapeutic efficacy and safety. Liquid oral formulations are preferred in most outpatient scenarios.

3. Safety Profile and Contraindications
Certain antibiotics such as tetracyclines are contraindicated in children under 8 years due to the risk of permanent tooth discoloration. Fluoroquinolones are generally avoided in pediatric patients due to concerns about cartilage and tendon development.

4. Route of Administration and Adherence
The oral route is the first choice for mild to moderate infections. Short treatment durations (5–7 days), pleasant-tasting liquid preparations, and fewer daily doses improve adherence in children. For severe infections with fever or poor oral intake, intravenous antibiotics may be required in a hospital setting.

✅ Anatomical and Physiological Differences
The anatomical structure of the maxillofacial region changes significantly from childhood to adulthood:

° In children, the jawbones are more porous and less mineralized, allowing for faster spread of infections into adjacent soft tissues (Borkar et al., 2020).
° In adults, denser bone structure typically leads to more localized infections, often presenting as periapical abscesses.

Additionally, primary teeth in children are closely associated with the developing permanent tooth buds, making untreated infections a potential threat to future dental development (Andreadis et al., 2021).

📌 Recommended Article :

PDF🔽 Antibiotics and its use in pediatric dentistry: A review ... The purpose of this review article is to provide information on proper use of antibiotics in pediatric dental practice for control of oral infection

✅ Etiology and Risk Factors
The root causes of odontogenic infections vary by age group:

° In children, the most common causes include deep caries in primary teeth, dental trauma, and issues related to tooth eruption.
° In adults, infections are often linked to chronic periapical disease, periodontal conditions, or post-extraction complications (Flynn, 2011).
° Systemic risk factors such as diabetes, cancer therapy, or immunosuppression increase susceptibility to severe odontogenic infections, especially in adults (Kuriyama et al., 2019).

📌 Recommended Article :

PDF 🔽 Guideline on use of antibiotic therapy for pediatric dental patients ... The use of antibiotic prophylaxis for dental patients at risk for infection is addressed in a separate best practices document.

✅ Clinical Presentation and Spread
The way odontogenic infections present and evolve differs significantly between children and adults:

° Pediatric patients often show rapid infection spread, leading to facial cellulitis, periorbital involvement, or submandibular swelling, frequently accompanied by fever and irritability (Auluck et al., 2020).
° Adults are more likely to present with localized abscesses, although delayed treatment can result in deep neck space infections or even mediastinitis.

Airway compromise is rare but poses a greater threat in adults due to fully developed fascial planes and deeper anatomical spaces.

✅ Diagnosis and Treatment

➤ Diagnosis
Diagnostic evaluation includes detailed history, clinical examination, and imaging such as periapical or panoramic X-rays. CT scans are warranted in advanced or deep space infections.
° In children, clinicians must assess tooth eruption stage and the proximity of infection to permanent tooth buds.
° In adults, factors such as past root canal treatments or the presence of periodontal disease are important in diagnosis.

➤ Treatment Approach
Treatment focuses on eliminating the source of infection (via extraction, root canal, or incision and drainage), systemic support, and appropriate antibiotic therapy.
° For pediatric patients, first-line antibiotics include amoxicillin or amoxicillin-clavulanate. Tetracyclines are contraindicated due to their adverse effects on tooth development (AAPD, 2022).
° In adults, a wider range of antibiotics can be used, including clindamycin for penicillin-allergic patients or metronidazole for anaerobic coverage.
Timely intervention in both groups is crucial to avoid systemic complications and long-term morbidity.

💬 Discussion
Anatomical, immunological, and developmental factors necessitate different clinical strategies when managing odontogenic infections in children and adults. In children, protecting the integrity of developing permanent teeth and facial structures is critical, requiring more conservative and preventive approaches. In adults, the presence of comorbidities and a higher likelihood of chronic infections demand comprehensive evaluation and individualized care.
Additionally, odontogenic infections continue to be a significant public health concern, especially when early dental care is neglected. Preventive dentistry, public education, and timely treatment are key to reducing the prevalence and severity of these infections across all age groups.

💡 Conclusion
While pediatric and adult odontogenic infections share a bacterial origin, they differ markedly in presentation, progression, and treatment needs. Dental professionals must understand these distinctions to provide safe, effective, and age-appropriate care. A tailored treatment approach not only improves clinical outcomes but also minimizes complications, especially in growing children and medically compromised adults.

Updated Criteria for the Selection of Antibiotic Dosage and Regimen in Dentistry

Antibiotic therapy in dentistry is essential for preventing and treating infections resulting from dental procedures.

📌 Recommended Article :

PDF 🔽 Antibiotics and its use in pediatric dentistry: A review ... Antibiotics are commonly used in dentistry for prophylactic as well as for therapeutic purposes. Very often antibiotics are used in unwarranted situations, which may give rise to resistant bacterial strains

Correct selection of antibiotic dosage and regimen not only ensures therapeutic efficacy but also minimizes the risk of developing bacterial resistance and adverse effects.

✅ A. Determining Factors in Antibiotic Selection

1. Identification of the Etiological Agent
Odontogenic infections are often polymicrobial, predominantly involving anaerobic and gram-positive aerobic bacteria. Precise identification of the causative agent allows for the selection of an antibiotic with an appropriate spectrum. However, due to the difficulty in isolating and culturing these microorganisms in daily practice, empirical selection based on local epidemiology and the nature of the infection is common.

2. Antibiotic Spectrum
The chosen antibiotic should be effective against the most common pathogens in odontogenic infections. For example, amoxicillin is effective against a wide range of gram-positive bacteria and some gram-negative ones, while clindamycin is preferred in patients allergic to penicillins due to its activity against anaerobes and gram-positive aerobes.

3. Pharmacokinetics and Pharmacodynamics
Understanding the absorption, distribution, metabolism, and excretion of the antibiotic is crucial for determining the dosage and frequency of administration. For instance, amoxicillin has good oral bioavailability and a half-life that allows for administration every 8 hours. Clindamycin, on the other hand, requires administration every 6 to 8 hours due to its shorter half-life.

4. Patient's Condition
The patient's systemic conditions, such as renal or hepatic insufficiency, can affect drug elimination, requiring dosage adjustments. Additionally, in immunocompromised patients, more aggressive or prolonged treatment may be necessary.

5. Possible Interactions and Adverse Effects
It is essential to consider drug interactions, especially in polymedicated patients. For example, erythromycin can interact with other drugs metabolized by the cytochrome P450 system, increasing the risk of toxicity. Moreover, some antibiotics can cause gastrointestinal adverse effects or allergic reactions that must be monitored.

° Pediatric dosage: 20–40 mg/kg/day divided into three doses.
° Considerations: In severe infections, the dose may be increased to 1 g every 8 hours. Dosage adjustment is recommended in patients with renal insufficiency.

2. Amoxicillin/Clavulanic Acid
° Indications: Resistant infections or when beta-lactamase-producing bacteria are suspected.
° Adult dosage: 875 mg/125 mg orally every 12 hours.
° Pediatric dosage: 25–45 mg/kg/day divided into two doses.
° Considerations: The combination with clavulanic acid broadens amoxicillin's spectrum but may increase the incidence of gastrointestinal effects.

3. Clindamycin
° Indications: Patients allergic to penicillins; infections by anaerobes.
° Adult dosage: 300 mg orally every 6–8 hours.
° Pediatric dosage: 8–20 mg/kg/day divided into three or four doses.
° Considerations: Monitor for gastrointestinal side effects and the risk of pseudomembranous colitis.

4. Azithromycin
° Indications: Patients allergic to penicillins; infections by susceptible bacteria.
° Adult dosage: 500 mg once daily for three days.
° Pediatric dosage: 10 mg/kg once daily for three days.
° Considerations: Has a prolonged half-life, allowing for simplified dosing regimens.

✅ C. Conclusions on the Selection of Antibiotic Dosage and Regimen in Dentistry

1. Evidence-Based Selection: The choice of antibiotics in dentistry should be based on the identification of the etiological agent, appropriate antibiotic spectrum, and updated clinical guidelines to ensure efficacy and safety in treating odontogenic infections.
2. Importance of Pharmacokinetics and Pharmacodynamics: Dosage and regimen should be adjusted considering the drug's absorption, metabolism, and excretion, as well as the patient's systemic condition, to avoid overdosing or bacterial resistance.
3. First-Line Antibiotics and Alternatives: Amoxicillin remains the antibiotic of choice for common dental infections, while clindamycin and azithromycin are safe options for patients with penicillin allergies.
4. Avoiding Antibiotic Abuse and Resistance: Empirical prescription should be prudent, considering the increasing bacterial resistance and the impact of indiscriminate antibiotic use on oral and general microbiota.
5. Individualized Treatment: Each patient should receive personalized antibiotic therapy, taking into account their clinical history, drug interactions, and potential adverse effects to optimize therapeutic response and reduce complications.

In conclusion, the rational use of antibiotics in dentistry is essential for effective infection treatment, minimizing risks, and contributing to the fight against microbial resistance.

A. What Is a Dental Infection?
A dental infection, or odontogenic infection, originates within the teeth or surrounding supporting structures and can spread to adjacent tissues if not promptly addressed. These infections typically begin when bacteria infiltrate the dental pulp—the innermost part of the tooth containing nerves and blood vessels—leading to inflammation and the formation of an abscess. Common causes include untreated dental caries (cavities), periodontal disease, or trauma to the tooth.

B. Signs and Symptoms of Dental Infection
Recognizing the early signs and symptoms of a dental infection is crucial for timely intervention. Common indicators include:
° Pain: Persistent, throbbing toothache that may radiate to the jawbone, neck, or ear.
° Sensitivity: Discomfort when consuming hot or cold foods and beverages.
° Swelling: Inflammation in the face or cheek, indicating the spread of infection.
° Fever: Elevated body temperature as the body responds to the infection.
° Swollen Lymph Nodes: Tenderness in the lymph nodes under the jaw or in the neck.
° Difficulty Swallowing or Breathing: Severe cases may lead to swelling that impinges on the throat, necessitating immediate medical attention.
If any of these symptoms are present, it is imperative to seek prompt dental care to prevent the infection from spreading and causing more severe health issues.

C. Common Severe Acute Dental Infections
° Pericoronitis: This infection occurs around the crown of a partially erupted tooth, often a wisdom tooth. Symptoms include redness, swelling, and pain in the gums. If untreated, it can lead to severe complications like Ludwig's angina or sepsis.
° Acute Dentoalveolar Abscess: A localized collection of pus in the alveolar bone at the root apex of a tooth, typically resulting from untreated dental caries or trauma. Symptoms include intense pain, swelling, and tenderness. Treatment involves drainage of the abscess and addressing the source of infection.
° Cellulitis: A diffuse inflammation of the soft tissues that can spread rapidly, leading to swelling, redness, and severe pain. It may result from untreated dental abscesses and can progress to life-threatening conditions if not managed promptly.

D. Treatment of Dental Infections
The primary goal in treating dental infections is to eliminate the source of infection and prevent its spread. Treatment strategies include:
° Drainage of Abscess: Incision and drainage procedures are performed to release pus and reduce pressure. This can be achieved through root canal therapy or tooth extraction, depending on the severity and location of the infection.
° Antibiotic Therapy: Antibiotics are prescribed to control and eradicate bacterial infections, especially if there are signs of systemic involvement or if the infection is spreading. The choice of antibiotic depends on the severity of the infection, patient age, and any known allergies. It's crucial to follow local guidelines and consult with a healthcare professional for individualized treatment plans.
