This article reviews the etiology, clinical signs, symptoms, updated treatment options, and differential diagnosis of herpes labialis, with a focus on relevance for dental professionals.

✅ Etiology
Herpes labialis is caused by Herpes Simplex Virus type 1 (HSV-1), an enveloped double-stranded DNA virus from the Herpesviridae family. Primary infection usually occurs during childhood through direct contact with infected saliva or lesions.
After initial infection, the virus establishes latency in the trigeminal ganglion, where it remains dormant. Reactivation may occur due to several triggers, including:

▪️ Emotional or physical stress
▪️ Fever or systemic illness
▪️ Ultraviolet light exposure
▪️ Immunosuppression
▪️ Hormonal changes

✅ Clinical Signs and Symptoms
Herpes labialis typically follows a predictable clinical course:

Prodromal Phase
▪️ Tingling, burning, or itching sensation
▪️ Mild erythema at the affected site

Vesicular Phase
▪️ Formation of clusters of small, fluid-filled vesicles
▪️ Lesions are usually painful and located on the vermilion border

Ulcerative and Crusting Phase
▪️ Vesicle rupture leading to shallow ulcers
▪️ Formation of a yellow-brown crust
▪️ Healing without scarring in immunocompetent patients
Systemic symptoms such as fever or lymphadenopathy may occur during primary infection but are uncommon in recurrent episodes.

Fluorosis vs. Enamel Demineralization: How to Identify Clinical Differences and Choose the Right Treatment

Dental fluorosis and enamel demineralization are common enamel alterations that may present with similar clinical appearances but differ significantly in etiology, progression, and management.

📌 Recommended Article :

Dental Article 🔽 Fluoride in Pediatric Dentistry: Dosage, Frequency, and Current Controversies ... Managing the behavior of the pediatric patient is a challenge for the pediatric dentist, since attending the office generates stress and uncertainty, causing some type of behavioral response.

Accurate differentiation is essential to avoid misdiagnosis and to implement appropriate preventive or therapeutic strategies. This article reviews the clinical characteristics, diagnostic considerations, and current treatment approaches for fluorosis and demineralization, providing practical guidance for dental professionals.

Advertisement

✅ Introduction
White enamel defects are frequently observed in both pediatric and adult dental patients. Among these, fluorosis and enamel demineralization represent two distinct pathological processes. While fluorosis is a developmental condition linked to excessive fluoride intake during enamel formation, demineralization is an acquired process related to biofilm activity and acid exposure. Misinterpretation may lead to ineffective or unnecessary treatment, highlighting the importance of proper clinical differentiation.

1. Dental Fluorosis

Etiology
Dental fluorosis results from excessive systemic fluoride ingestion during amelogenesis, typically before the age of eight. The excess fluoride disrupts enamel mineralization, leading to increased porosity.

Clinical Characteristics
▪️ Symmetrical distribution affecting homologous teeth
▪️ Diffuse white opacities, striations, or mottling
▪️ In moderate to severe cases, brown discolorations and surface pitting
▪️ Lesions are present at eruption and do not progress over time

Treatment Options
Management depends on severity:
▪️ Mild fluorosis: No treatment or enamel polishing
▪️ Moderate fluorosis: Resin infiltration or microabrasion
▪️ Severe fluorosis: Composite restorations or porcelain veneers

Modern approaches such as the Hall Technique, SMART, and ART offer evidence-based alternatives that avoid drilling, reduce fear, and improve cooperation in young patients.

2. Enamel Demineralization

Etiology
Enamel demineralization is caused by prolonged exposure to acids produced by cariogenic bacteria. It commonly occurs around orthodontic brackets or in areas of poor oral hygiene.

Clinical Characteristics
▪️ Chalky white spot lesions with well-defined borders
▪️ Typically localized and asymmetrical
▪️ Lesions develop after tooth eruption
▪️ May progress to cavitated carious lesions if untreated

Treatment Options
▪️ Topical fluoride therapy (varnishes, gels)
▪️ Casein phosphopeptide–amorphous calcium phosphate (CPP-ACP)
▪️ Resin infiltration for non-cavitated lesions
▪️ Restorative treatment if cavitation is present

📊 Comparative Table: Fluorosis vs. Enamel Demineralization

Clinical Parameter	Fluorosis	Enamel Demineralization
Time of Onset	During tooth development	After tooth eruption
Lesion Distribution	Symmetrical and generalized	Localized and asymmetrical
Progression	Non-progressive	Progressive if untreated
Primary Management	Esthetic-focused treatment	Remineralization and caries control

💬 Discussion
Although both conditions present as white enamel defects, fluorosis is a developmental and non-progressive condition, whereas demineralization is an active, biofilm-mediated process. The timing of lesion appearance, symmetry, and surface texture are critical diagnostic clues. Adjunctive tools such as quantitative light-induced fluorescence (QLF) may support diagnosis but do not replace thorough clinical examination.

🎯 Clinical Recommendations
▪️ Always assess patient age and fluoride exposure history
▪️ Evaluate lesion symmetry, borders, and location
▪️ Avoid aggressive treatment in mild fluorosis
▪️ Implement early remineralization protocols for demineralization
▪️ Educate patients and caregivers on fluoride use and oral hygiene

✍️ Conclusion
Distinguishing fluorosis from enamel demineralization is essential for accurate diagnosis and appropriate management. Understanding their distinct etiologies and clinical behaviors allows clinicians to deliver targeted, conservative, and effective treatments, improving both functional and esthetic outcomes.

Apicoectomy in Children and Adolescents: When Is It Truly Indicated?

Apicoectomy is a well-established endodontic surgical procedure in adult patients; however, its indication in children and adolescents remains controversial due to ongoing root development, anatomical variability, and high regenerative potential.

📌 Recommended Article :

Dental Article 🔽 Pediatric Tooth Extraction Techniques: Step-by-Step Clinical Approach ... A clear understanding of anatomical and biological differences, along with appropriate instrumentation and technique, is essential to ensure safe and predictable outcomes.

This article critically analyzes when apicoectomy is truly indicated in pediatric and adolescent patients, highlighting biological considerations, clinical justifications, and key differences compared to adult procedures, based on current scientific evidence.

Advertisement

✅ Introduction
Endodontic surgery aims to eliminate persistent periapical pathology when conventional root canal treatment fails. While apicoectomy is widely accepted in adults, its use in younger patients must be approached with caution. Immature apices, open root canals, proximity to tooth germs, and superior healing capacity significantly influence decision-making in pediatric cases.

Although some babies with tongue-tie feed without difficulty, others experience poor latch, ineffective milk transfer, and early breastfeeding challenges, which may lead to frustration for both infants and parents.

✅ Biological and Anatomical Considerations in Children and Adolescents
Developing teeth present distinct characteristics:

▪️ Incomplete root formation
▪️ Wide apical foramina
▪️ High vascularization and cellular activity
▪️ Proximity to permanent tooth buds
These factors often favor conservative and regenerative approaches over surgical intervention.

📌 Recommended Article :

Dental Article 🔽 Clinical Indications for Frenectomy in Pediatric Dentistry: Evidence-Based Guidelines ... Frenectomy is a common surgical procedure in pediatric dentistry aimed at correcting abnormal frenum attachments that interfere with oral function, growth, and development.

✅ Indications for Apicoectomy in Pediatric and Adolescent Patients
Apicoectomy should be considered only when less invasive treatments have failed or are contraindicated. Accepted indications include:

▪️ Persistent periapical lesions after adequate nonsurgical retreatment
▪️ Apical pathology associated with fractured instruments inaccessible via orthograde access
▪️ Anatomical obstructions preventing complete canal disinfection
▪️ Symptomatic lesions compromising adjacent structures
Importantly, apicoectomy is not a first-line treatment in immature permanent teeth.

Dental Article 🔽 Bleeding After a Tooth Extraction: How to Stop It Safely ... Bleeding after a dental extraction is common and usually normal, especially during the first hours. However, knowing what is normal, how to control bleeding, and when to seek help is essential for proper healing.

✅ Differences Between Pediatric and Adult Apicoectomy
Key differences include:

Higher healing potential in younger patients
Greater risk of disrupting root development
Lower tolerance for surgical trauma
Preference for regenerative endodontics in children
Adults typically present with fully developed apices, making surgical outcomes more predictable.

📊 Comparative Table: Apicoectomy in Pediatric vs. Adult Patients

Clinical Factor	Pediatric / Adolescent Patients	Adult Patients
Root development	Often incomplete, open apex	Fully developed roots
Healing capacity	High regenerative potential	Moderate regenerative capacity
Preferred treatment	Conservative or regenerative approaches	Surgical intervention acceptable
Risk profile	Higher risk of affecting tooth development	Lower developmental risk

💬 Discussion
Recent literature emphasizes that regenerative endodontic procedures (REPs) and apexification techniques should be prioritized in immature teeth. Surgical intervention may compromise continued root maturation and periodontal attachment. Therefore, apicoectomy must be justified by clear clinical failure of conservative therapy, supported by radiographic and clinical findings.

🎯 Clinical Recommendations
▪️ Exhaust nonsurgical and regenerative options before considering surgery
▪️ Avoid apicoectomy in teeth with active root development unless absolutely necessary
▪️ Use CBCT imaging for accurate diagnosis and surgical planning
▪️ Ensure multidisciplinary evaluation in complex pediatric cases

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.

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.

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.

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.

💬 Discussion
The principles proposed by Peterson et al. provide a structured and reproducible approach to managing odontogenic infections. Their strength lies in emphasizing early surgical intervention, patient-centered care, and judicious antibiotic use. In the context of rising antimicrobial resistance, adherence to these principles is more relevant than ever in contemporary dental practice.

✍️ Conclusion
The successful management of odontogenic infections depends on strict adherence to evidence-based principles, including accurate diagnosis, timely surgical intervention, appropriate antibiotic selection, and close patient monitoring. Applying the Peterson protocol systematically reduces complications and improves clinical outcomes.

Management of Bruxism with Night Guards: An Updated Guide for Dental Professionals

Bruxism is a common parafunctional activity characterized by involuntary clenching or grinding of teeth, occurring during sleep or wakefulness. It is associated with tooth wear, temporomandibular disorders (TMD), muscle pain, and restorative complications.

📌 Recommended Article :

Dental Article 🔽 Antibiotic Prophylaxis in Pediatric Dentistry: When and How to Use It Safely in 2025 ... Antibiotic prophylaxis in pediatric dentistry is a preventive measure used to avoid serious systemic infections, such as infective endocarditis, in children undergoing dental procedures.

Current evidence indicates that bruxism has a multifactorial etiology, including central nervous system regulation, psychosocial factors, and sleep-related mechanisms.

Dental Article 🔽 Night Guards: Do They Really Help with Bruxism? ... It can occur during sleep (sleep bruxism) or while awake (awake bruxism) and is associated with tooth wear, temporomandibular disorders, and orofacial pain.

✅ Understanding Bruxism: Clinical Considerations
Bruxism is classified as:

▪️ Sleep bruxism, a sleep-related movement disorder.
▪️ Awake bruxism, often associated with stress and behavioral factors.
Clinical diagnosis relies on patient history, clinical signs (wear facets, fractures), muscle tenderness, and, in selected cases, instrumental assessments. Accurate diagnosis is essential to avoid overtreatment and to select appropriate management strategies.
