Introduction
Historically, Baby Bottle Tooth Decay referred to a specific pattern of dental caries in infants associated with prolonged bottle feeding, especially with sweetened liquids during sleep. However, research in recent decades has shown that this terminology is limited, as caries in young children arise from multiple risk factors, not just feeding habits.
To address this, the American Academy of Pediatric Dentistry (AAPD) introduced the term Early Childhood Caries (ECC) — defined as the presence of one or more decayed, missing, or filled tooth surfaces in any primary tooth of a child under six years old (AAPD, 2023). This broader perspective allows for a comprehensive, preventive, and biological approach to pediatric oral health.

Etiology and Pathogenesis
ECC is a biofilm-mediated, sugar-driven, dynamic disease resulting from an imbalance between demineralization and remineralization. The key etiologic components include:

▪️ Cariogenic bacteria (Streptococcus mutans, Lactobacillus spp.)
▪️ Frequent exposure to fermentable carbohydrates
▪️ Host factors, such as enamel hypoplasia or reduced saliva flow
▪️ Socio-behavioral determinants, including parental education and socioeconomic status

Recent studies (Berkowitz, 2022; Tinanoff et al., 2023) highlight that the oral microbiome composition plays a critical role, with early colonization of S. mutans strongly associated with rapid lesion development.

Clinical Presentation
The initial lesions appear as chalky white spots on the smooth surfaces of the maxillary incisors, followed by brown discoloration and cavitation. In advanced cases, caries may involve multiple teeth, leading to:

▪️ Pain and infection
▪️ Difficulty eating or sleeping
▪️ Premature tooth loss and potential malocclusion

Lower incisors are often spared due to protection from the tongue and saliva, a key clinical distinction in diagnosis.

Diagnosis
Diagnosis should combine visual-tactile inspection with caries detection technologies such as:

▪️ ICDAS II system for lesion classification
▪️ Laser fluorescence (DIAGNOdent) for early detection
▪️ Bitewing radiographs to assess interproximal involvement

Risk assessment tools such as the AAPD Caries Risk Assessment Tool (CAT) and CAMBRA for children help clinicians develop individualized preventive plans.

Modern Preventive Strategies

1. Parental Education and Behavior Modification
Educating caregivers remains essential. Key measures include:
▪️ Avoiding night-time bottle feeding with anything other than water.
▪️ Initiating toothbrushing with fluoride toothpaste (1000 ppm) when the first tooth erupts.
▪️ Weaning from the bottle by 12–14 months.
▪️ Reinforcing fluoride exposure through toothpaste, varnishes, and community programs.

2. Fluoride-Based Approaches
Recent studies confirm the efficacy of 5% sodium fluoride varnish for preventing ECC and remineralizing white spot lesions (Marinho et al., 2021). In cases of active caries, Silver Diamine Fluoride (SDF 38%) has emerged as a non-invasive alternative capable of arresting lesions with minimal discomfort — a valuable tool for uncooperative or medically compromised children.

3. Probiotic and Microbiome Modulation
New evidence suggests that oral probiotics containing Lactobacillus rhamnosus GG and Bifidobacterium lactis may reduce S. mutans levels and modulate the oral microbiome, although results remain preliminary (Aparna et al., 2023).

Modern Treatment Modalities

1. Minimally Invasive Dentistry (MID)
The focus has shifted toward preserving healthy tooth structure.
▪️ Atraumatic Restorative Treatment (ART): Uses high-viscosity glass ionomer cements (GICs) that release fluoride and bond chemically to enamel.
▪️ Resin infiltration (Icon system): Effective for non-cavitated lesions to halt progression.

2. Bioactive Restorative Materials
Innovations such as bioactive glass ionomer and calcium silicate-based materials (ACTIVA BioACTIVE, Cention N) provide ion release, enhancing remineralization and promoting enamel repair (Santanoni et al., 2023).

3. Hall Technique
The Hall technique, which seals carious lesions under preformed stainless steel crowns without caries removal, has shown high success rates (Innes et al., 2022) and reduces the need for local anesthesia.

4. Pulp Therapy Advances
In cases of pulpal involvement, bioceramic materials like Mineral Trioxide Aggregate (MTA) and Biodentine offer superior sealing ability, biocompatibility, and dentin bridge formation compared to traditional calcium hydroxide (Stringhini et al., 2023).

5. Behavior Management and Sedation
For extensive cases or young uncooperative patients, conscious sedation (nitrous oxide) or general anesthesia may be required, ensuring complete oral rehabilitation and prevention of future disease progression.

💬 Discussion
The paradigm shift from Baby Bottle Tooth Decay to Early Childhood Caries represents more than a change in terminology — it reflects a modern understanding of caries as a chronic, multifactorial disease.
Recent evidence supports the integration of bioactive, fluoride-releasing restorative systems and non-invasive techniques such as SDF and ART. Moreover, addressing behavioral and microbiological factors remains key to long-term control.
Public health programs incorporating fluoride varnish applications, caregiver counseling, and community-level interventions have demonstrated measurable reductions in ECC incidence, especially in low-income populations (WHO, 2022).

✍️ Conclusion
Early Childhood Caries remains a major public health concern despite being largely preventable. Modern approaches emphasize early detection, biofilm control, fluoride use, and minimally invasive management. Pediatric dentists should integrate behavioral guidance, restorative innovation, and interprofessional collaboration to ensure comprehensive care.
The evolution from “Baby Bottle Tooth Decay” to “Early Childhood Caries” reflects the profession’s ongoing commitment to evidence-based, preventive, and patient-centered dentistry.

📌 Recommended Article :
Dental Article 🔽 Anatomical Landmarks in Dental Anesthetic Techniques: A Complete Clinical Review ... Understanding the anatomical landmarks in dental anesthesia is crucial for achieving effective pain control and minimizing complications.
Preoperative Assessment

1. Medical History and Risk Evaluation
A thorough medical history identifies potential systemic conditions that may complicate anesthesia. Particular attention should be given to:
▪️ Respiratory diseases (e.g., asthma, recent upper respiratory infections)
▪️ Cardiovascular disorders
▪️ Neurological or metabolic conditions
▪️ Allergies to anesthetic agents or latex
Assessment tools such as the American Society of Anesthesiologists (ASA) classification are essential for determining anesthetic risk. Children classified as ASA I–II are generally suitable for in-office procedures, while ASA III–IV may require hospital settings.

2. Physical Examination
A detailed physical examination should include evaluation of airway anatomy, weight, and vital signs. Airway assessment helps predict possible intubation difficulties. Weight-based dosing ensures correct anesthetic administration and prevents toxic reactions.

3. Fasting and Preoperative Instructions
To prevent aspiration during anesthesia, adherence to fasting guidelines is mandatory. The American Academy of Pediatrics (AAP) recommends:
▪️ Clear liquids: up to 2 hours before
▪️ Breast milk: up to 4 hours before
▪️ Solid food or formula: at least 6 hours before
Parents should also be informed about postoperative care and signs of potential complications.

4. Psychological and Behavioral Preparation
Anxiety and fear are significant barriers in pediatric dental procedures. Preoperative psychological preparation, such as tell-show-do techniques, parental presence, and behavioral modeling, enhances cooperation and reduces anesthesia-related stress.

Pediatric vs Adult Anatomical Differences in Local Anesthesia: Clinical Implications for Dental Practice

Dental Anesthesia

Abstract
Local anesthesia is a cornerstone of pain management in dentistry. However, anatomical differences between pediatric and adult patients significantly influence the technique, depth, and dosage of anesthetic administration.

📌 Recommended Article :
Dental Article 🔽 Anatomical Landmarks in Dental Anesthetic Techniques: A Complete Clinical Review ... Understanding the anatomical landmarks in dental anesthesia is crucial for achieving effective pain control and minimizing complications.
Understanding these differences is essential to ensure safe, effective, and atraumatic anesthesia in both populations.

Introduction
Dental local anesthesia aims to temporarily block nerve conduction, allowing painless treatment. Yet, the anatomical variability between children and adults modifies the approach for each anesthetic technique, including infiltration, inferior alveolar nerve block (IANB), mental nerve block, posterior superior alveolar (PSA), and palatal injections. Clinicians must adapt their injection site, depth, and anesthetic volume to the patient’s age and anatomical development.

📌 Recommended Article :
Dental Article 🔽 Local Anesthetic Techniques in Dentistry: Injection Sites, Depth, and Safe Volumes ... The precision of local anesthesia in dentistry relies on correct identification of injection sites, penetration depth, and dosage volumes.
Anatomical Differences and Their Clinical Relevance

1. Bone Density and Porosity
In children, maxillary and mandibular bones are more porous and less mineralized, allowing anesthetic diffusion through bone. Therefore, infiltration techniques are often effective in pediatric patients, while nerve blocks are required more frequently in adults due to cortical bone density (Malamed, 2020).

2. Position of Foramina
▪️ Infraorbital foramen: Located lower in children; approximately at the level of the primary canine, moving upward with growth.
▪️ Mental foramen: In children, it lies near the primary molar apex; in adults, near the second premolar.
▪️ Mandibular foramen: Positioned lower and more posterior in children, which requires higher needle insertion points in adults for IANB.

These changes dictate the angle and depth of needle insertion in mandibular blocks.

3. Nerve Pathways and Soft Tissue Thickness
Children have shorter nerve trunks and thinner soft tissues, resulting in shorter needle penetration (average 15 mm in children vs 20–25 mm in adults) and lower anesthetic volumes. In adults, increased muscle mass and tissue resistance require greater pressure and depth during injection.

4. Root Development and Landmarks
Incomplete root formation in primary and mixed dentition alters the location of apices and nerve proximity, demanding precise anatomical awareness to avoid intravascular or intrapulpal injections.

📊 Comparative Table: Clinical Techniques in Pediatric and Adult Local Anesthesia

Aspect Pediatric Characteristics Adult Characteristics
Maxillary Infiltration Porous bone allows rapid anesthetic diffusion; smaller volume (0.5–1.0 mL) provides effective anesthesia. Dense cortical bone requires higher volume (1.0–2.0 mL) and longer onset time for full anesthesia.
Inferior Alveolar Nerve Block Mandibular foramen located lower and posterior; shallower insertion depth (≈15 mm) ensures safety and accuracy. Mandibular foramen positioned higher; deeper needle insertion (20–25 mm) needed for complete nerve block.
Mental Nerve Block Foramen near primary molar apex; smaller field of anesthesia and lower anesthetic volume (0.3–0.6 mL). Foramen near second premolar; wider field coverage and volume around 0.6–1.0 mL.
Palatal Injection Thinner mucosa allows low-pressure deposition (0.1–0.2 mL); minimal discomfort if performed slowly. Thicker keratinized mucosa requires higher injection pressure; volume typically 0.2–0.3 mL.
💬 Discussion
The success of local anesthesia depends on recognizing the patient’s anatomical stage. In pediatric dentistry, infiltration techniques are often preferred due to bone permeability and reduced nerve depth, minimizing pain and risk. In contrast, adults require deeper and more targeted injections, especially for mandibular anesthesia, where osseous density limits anesthetic diffusion (Meechan & Malamed, 2021). Clinicians must also consider physiological differences—such as smaller body weight and systemic absorption rates in children—to prevent toxicity.

✍️ Conclusion
Understanding pediatric versus adult anatomical differences is fundamental for safe and predictable local anesthesia. Proper adaptation of technique, depth, and volume enhances both analgesic efficacy and patient comfort. Continuous anatomical education is crucial to reduce complications such as nerve injury or inadequate anesthesia.

🔎 Recommendations

1. Always adjust anesthetic volume and concentration according to age and weight.
2. Use shorter needles for pediatric mandibular blocks to prevent overinsertion.
3. Palpate anatomical landmarks before injection to locate foramina accurately.
4. Update training regularly with 3D anatomical references and simulation-based learning.

Interdisciplinary Management of Cleft Lip and Palate: A Comprehensive Dental and Medical Approach

Cleft Lip and Palate

Abstract
Cleft lip and palate (CLP) represent one of the most common craniofacial anomalies, requiring a coordinated interdisciplinary approach that integrates surgical, orthodontic, speech, and psychosocial management.

📌 Recommended Article :
PDF 🔽 Mandibular tumors in pediatric patients. Report of 04 cases of aggressive tumors ... In these cases, the use of images and a biopsy is necessary to determine the histopathology of the lesion and carry out an appropriate treatment plan.
This article reviews current knowledge about the etiology, clinical characteristics, and treatment strategies of CLP, emphasizing the role of collaboration among specialists for optimal outcomes.

Introduction
Cleft lip and palate are congenital deformities affecting the upper lip and the roof of the mouth (palate). These anomalies occur when facial structures fail to fuse properly during embryonic development, typically between the 4th and 12th weeks of gestation. The condition can appear as an isolated cleft lip, cleft palate, or both combined, and its severity varies widely among individuals.
Globally, the incidence of CLP ranges between 1 in 700 live births, with variations based on ethnicity, genetics, and environmental factors (Mossey et al., 2021). These conditions not only affect aesthetic appearance, but also have implications for speech, feeding, hearing, and psychosocial development.

Etiology
The etiology of cleft lip and palate is multifactorial, involving both genetic predisposition and environmental influences.

▪️ Genetic factors: Mutations or deletions in genes such as IRF6, MSX1, and TBX22 are strongly associated with CLP (Yu et al., 2022).
▪️ Environmental factors: Maternal smoking, alcohol consumption, folic acid deficiency, uncontrolled diabetes, and exposure to certain anticonvulsant medications during pregnancy increase the risk.
▪️ Syndromic vs. Non-syndromic forms: CLP can occur in isolation (non-syndromic) or as part of a syndrome (e.g., Van der Woude, Pierre Robin sequence).

Development and Clinical Characteristics
The cleft lip results from failure of fusion between the maxillary and medial nasal processes, while cleft palate arises from non-fusion of the palatal shelves.

▪️ Unilateral clefts affect one side of the lip or palate.
▪️ Bilateral clefts involve both sides and are often more severe.
▪️ Submucous clefts may go unnoticed but can still cause speech and feeding difficulties.

Common clinical features include difficulty in breastfeeding, nasal regurgitation, recurrent ear infections, dental anomalies, and altered speech resonance.

Interdisciplinary Management
The management of CLP requires a multidisciplinary team, often coordinated through cleft care centers. Key professionals include:

▪️ Plastic and maxillofacial surgeons: Perform surgical repair, typically at 3–6 months (lip) and 9–18 months (palate).
▪️ Orthodontists: Guide maxillary growth and dental alignment.
▪️ Speech therapists: Address speech articulation and resonance.
▪️ Otolaryngologists: Manage ear infections and hearing loss.
▪️ Psychologists and social workers: Support family adaptation and self-esteem.
▪️ Pediatric dentists: Prevent dental caries and monitor eruption anomalies.

Modern treatment emphasizes early intervention, long-term follow-up, and family-centered care to optimize function and aesthetics (Becker et al., 2023).

📊 Comparative Table: Characteristics of Cleft Lip and Palate

Aspect Advantages Limitations
Cleft Lip Early surgical correction improves aesthetics and feeding May cause nasal deformities and lip scarring
Cleft Palate Improved speech and feeding after palatoplasty Risk of velopharyngeal insufficiency and speech delay
Combined Cleft Lip and Palate Comprehensive treatment enhances facial symmetry and function Requires multiple surgeries and long-term multidisciplinary care

💬 Discussion
The interdisciplinary approach ensures that every aspect of the patient’s health—functional, aesthetic, and psychological—is addressed. Early coordination between specialists prevents growth disturbances and promotes normal speech development. Advances such as presurgical orthopedics, 3D surgical planning, and genetic counseling are transforming outcomes for CLP patients. However, in many low-resource settings, limited access to specialized care remains a significant barrier.

Partial pulpotomy vs. Conventional (full) pulpotomy in primary teeth — a comparative, evidence-based review

Pulpotomy

Abstract
This article compares partial pulpotomy and conventional (full/coronal) pulpotomy in primary teeth, focusing on definitions, technique differences, materials, clinical outcomes, and benefits.

📌 Recommended Article :
Video 🔽 Pulpotomy and pulpectomy procedures. Indications and Differences ... We share the similarities, differences, indications, contraindications and step-by-step procedures of pulpotomy and pulpectomy.
Recommendations and recent evidence from guidelines and systematic reviews are summarized to inform pediatric dental practice.

Advertisement


Introduction
Vital pulp therapy in primary teeth aims to preserve radicular pulp vitality, maintain space, and avoid extraction/pulpectomy where possible. The choice between a partial pulpotomy (limited removal of coronal pulp) and a conventional/full pulpotomy (complete removal of coronal pulp) depends on pulp status, exposure etiology (trauma vs caries), clinical signs, and material availability. Recent guideline updates and meta-analyses have refined indications and shown high overall success rates for pulpotomy procedures under appropriate conditions.

Definitions
• Partial pulpotomy (also called Cvek pulpotomy in many contexts): surgical removal of a limited portion (typically ~1–3 mm) of inflamed coronal pulp beneath an exposure, leaving most coronal pulp intact to preserve vitality and promote repair. It is commonly used after traumatic exposures and selected carious exposures when the remaining pulp appears healthy.
• Conventional (full or coronal) pulpotomy: removal of the entire coronal pulp tissue to the level of the canal orifices, followed by placement of a medicament over radicular pulp stumps and definitive coronal restoration. It is widely used for primary molars with carious exposures when radicular pulp is judged capable of healing.

Similarities

• Both are forms of vital pulp therapy (VPT) that aim to preserve radicular pulp vitality and avoid pulpectomy or extraction.
• Both require hemostasis, an aseptic technique, and a hermetic coronal seal with a definitive restoration to prevent bacterial leakage.
• Success in both procedures depends on case selection, operator skill, and appropriate post-op follow-up (clinical + radiographic).

📌 Recommended Article :
Dental Article 🔽 Pulp Polyps in Children: Causes, Diagnosis, and Treatment Options in Pediatric Dentistry ... While it is a protective response to chronic inflammation, it reflects significant pulpal exposure, often requiring endodontic or surgical management.
Differences — techniques and clinical steps

➤ Partial pulpotomy
• Indication: small pulp exposures (trauma is classic indication) or carious exposures when the coronal inflammation is limited and the remaining pulp looks healthy.
• Procedure steps (typical):
1. Remove superficial inflamed pulp tissue ~1–3 mm (or until healthy bleeding tissue encountered).
2. Achieve controlled hemostasis (gentle pressure with saline/sterile cotton; should stop in a few minutes).
3. Place a biocompatible pulp dressing (e.g., MTA, Biodentine, calcium hydroxide, or newer calcium silicate cements).
4. Restore with durable coronal seal (glass ionomer + stainless steel crown or appropriate restoration).

➤ Conventional (full/coronal) pulpotomy
• Indication: deeper carious exposures where coronal pulp is judged inflamed but radicular pulp may still be healthy (commonly used in primary molars).
• Procedure steps (typical):
1. Remove entire coronal pulp down to canal orifices.
2. Achieve hemostasis at canal orifices.
3. Place pulp medicament over radicular stumps (historically formocresol, calcium hydroxide; increasingly MTA, Biodentine, or iRoot/Bioceramics are used).
4. Definitive coronal restoration (often stainless steel crown in primary molars).

Video 🔽 Apexogenesis: Step by step procedure ... Apexogenesis is performed on immature teeth with open apices that are affected by caries, trauma, or fractures with pulp exposure. Follow-up and clinical controls are recommended.
Differences — materials (common choices and evidence)

• Calcium hydroxide (CH): traditional agent; can induce reparative dentin but associated with higher internal resorption and lower long-term success in some studies.
• Mineral trioxide aggregate (MTA): strong evidence for higher success and better tissue response than CH in primary molar pulpotomies (less internal resorption, thicker dentinal bridge), though it can cause crown discoloration and is more costly. A randomized trial reported ~94% success for MTA vs ~65% for CH in primary molars (small RCT).
• Biodentine & other calcium-silicate cements: growing evidence suggests comparable outcomes to MTA in many settings and advantages such as improved handling and faster setting in some formulations; recent systematic reviews/meta-analyses have examined these comparisons in primary teeth.

📌 Recommended Article :
Dental Article 🔽 Myths About Root Canal Treatment ... This article addresses and debunks these common misconceptions, providing accurate information to promote informed decisions about dental health.
Clinical outcomes & success rates — what the recent evidence shows

• Recent meta-analysis/systematic review data indicate high overall success rates for pulpotomy in primary teeth when performed for appropriate indications: pooled 6- and 12-month success rates reported in some reviews exceed 90% under selected conditions. However, heterogeneity in study design, materials, and follow-up remains.
MTA shows higher success compared with calcium hydroxide in randomized trials of primary molars (example RCT: MTA ~94% vs CH ~65%).
Partial pulpotomy (when properly indicated, e.g., traumatic exposures or selective carious exposures) demonstrates excellent success in many reports and is increasingly accepted as the conservative option for appropriately selected primary and permanent teeth. Systematic reviews of traumatic exposures report pooled success rates often in the high 80s–90s%.

📌 Recommended Article :
Video 🔽 Pulpectomy, everything you need to know: Diagnosis, indications, and filling materials ... Pulpectomy is a dental procedure that is performed on primary teeth that are affected by an infectious process that totally compromises the dental pulp.
Benefits

➤ Benefits when partial pulpotomy may be preferred
More conservative: preserves more pulp tissue and potential for continued physiologic function.
Simpler and quicker: less pulp removal, often easier hemostasis, and preservation of tooth structure.
High success in traumatic exposures: excellent evidence supports partial pulpotomy after trauma, making it the treatment of choice for many exposed traumatized teeth.
Lower risk of devitalization-related sequelae: by preserving more vital tissue, risk of certain complications may be reduced if case selection is correct.

➤ Benefits of conventional/full pulpotomy:
Established for carious exposures in primary molars with extensive coronal pulp involvement when radicular pulp is likely healthy.
• When MTA or modern calcium silicate cements are used, conventional pulpotomy outcomes are excellent and may avoid need for pulpectomy/extraction.

Practical considerations & clinical decision points

• Etiology matters: Traumatic exposures often favor partial pulpotomy; carious exposures often lead clinicians to full pulpotomy, although selected carious exposures may be amenable to partial pulpotomy with careful assessment.
• Hemostasis test: inability to achieve hemostasis within a few minutes after pulp amputation suggests deeper inflammation and may indicate need to convert to pulpotomy/pulpectomy or extraction.
• Material selection: current guideline and trial evidence favors bioceramic materials (MTA, Biodentine, iRoot) over CH for better outcomes in many settings. Cost, handling, and esthetic considerations (discoloration with some MTA formulations) should be weighed.
• Seal and restoration: a durable coronal seal (often a stainless steel crown in primary molars) is critical for long-term success.

🦷 Clinical Flowchart: Decision Process — Partial vs. Conventional Pulpotomy in Primary Teeth

Clinical Step Assessment or Finding Recommended Treatment Key Notes
1. Initial Diagnosis No spontaneous pain, normal mobility, no radiolucency Candidate for vital pulp therapy Confirm tooth restorable and pulp potentially vital
2. Exposure Etiology Traumatic pulp exposure with minimal contamination Partial pulpotomy Remove 1–3 mm of inflamed tissue; ideal for trauma cases
3. Carious Exposure Deep caries, small exposure, bleeding easily controlled Partial pulpotomy or Full pulpotomy Decision depends on depth of inflammation and hemostasis
4. Hemostasis Evaluation Bleeding stops within 5 minutes with gentle pressure Partial pulpotomy Indicates superficial inflammation and healthy radicular pulp
5. Hemostasis Difficult to Achieve Bleeding persists beyond 5 minutes or dark blood present Full pulpotomy Remove entire coronal pulp to canal orifices
6. Pulp Status After Amputation Healthy bleeding tissue at orifices Full pulpotomy Apply MTA or Biodentine; avoid formocresol
7. Pulp Exposure Size Small (≤1 mm) Partial pulpotomy may suffice Especially if recent exposure and asymptomatic
8. Material Selection MTA, Biodentine, or bioceramic cement For both techniques High biocompatibility, promotes dentin bridge formation
9. Coronal Seal Immediate restoration with glass ionomer + SSC Mandatory for both Ensures long-term success and prevents microleakage
10. Follow-up Clinical & radiographic check at 6–12 months Both procedures Look for absence of symptoms, resorption, or radiolucency

💬 Discussion
Contemporary evidence (systematic reviews and updated AAPD guidance) supports a broader role of vital pulp therapies in primary teeth than historically believed, with high short- to medium-term success rates when case selection, technique, and materials are appropriate. The AAPD Vital Pulp Therapy guideline (systematic review to July 2022) provides an evidence-based framework for selecting pulpotomy vs other treatments and emphasizes the importance of case selection, asepsis, hemostasis, and a good coronal seal.
While partial pulpotomy is classically favored for traumatic exposures, evidence from meta-analyses indicates it can be an effective conservative option even in some carious exposures — but the clinician must carefully evaluate the extent of inflammation and ability to control bleeding. Conversely, conventional pulpotomy remains a reliable standard for many primary molars with carious exposure, especially when modern bioceramic materials (MTA, Biodentine) are used — these appear to perform better than calcium hydroxide in randomized trials.
Limitations in the evidence base include variability in follow-up duration, outcome definitions, and heterogeneity of materials used across studies. Long-term comparative trials with standardized protocols and longer follow-up would further clarify optimal indications for partial vs full pulpotomy in primary teeth.

✍️ Conclusion
Both partial and conventional pulpotomy are valid vital pulp therapies for primary teeth when performed with correct indication, aseptic technique, hemostasis, appropriate medicament (increasing evidence for MTA/bioceramics), and a durable coronal seal.
Partial pulpotomy is more conservative and shows excellent success in traumatic exposures and selected carious cases when the remaining pulp is healthy and hemostasis is achievable.
Conventional/full pulpotomy, especially when using MTA or Biodentine, provides high success rates for primary molars and may be preferable when coronal pulp removal is required.
• Clinicians should follow current evidence-based guidelines (e.g., AAPD) and apply individualized judgment for each case.
