Aim: This is a retrospective cross-sectional study of oral and maxillofacial biopsies in paediatric population, up to 16 years of age from 1991 to 2021. This study aimed to investigate the frequency, demographic and clinicopathological characteristics of paediatric biopsies according to the diagnosis categories of the main tertiary centre in Malaysia.
Methods: A total of 17294 histopathological reports from Diagnostic Oral Pathology Unit between 1991 and 2021 were retrieved. One thousand eleven histopathological reports that fulfilled the inclusion and exclusion criteria were included. Information of interest was extracted from histopathological reports. The lesions were categorised into 10 diagnosis categories. Descriptive and correlation analysis were performed.
Results: Paediatric oral and maxillofacial biopsies accounted for 5.9% of the total biopsies received. The peak incidence of diagnosis was in age range of 12 to 16 years old and mean age of 11.6 years old (±3.5), with female preponderance. The most common category of diagnosis was salivary gland pathology with mucocele (30%) being the most frequently diagnosed lesions. Lip and labial mucosa were the commonest site of occurrence. Specimen sizes smaller than 1 cm were the most common specimen diameter with mean size of 1.6 cm (±1.5). Age, site of occurrence and specimen size were statistically significant (P < 0.05) with paediatric oral and maxillofacial biopsies.
Conclusion: This is a large-scale study of paediatric oral and maxillofacial biopsies of a tertiary centre over three decades. We hope this data is useful for chairside assessment and aids in diagnosis making.

Objectives: To assess the usefulness of sentinel lymph node biopsy (SLNB) in patients with early-stage oral squamous cell carcinoma (OSCC).
Materials And Methods: Seventy-five patients (mean age 62 years) diagnosed with cT1-2 N0 underwent SLNB with Tc, lymphoscintigraphy/SPECT-CT, and gamma probe detection with intraoperative histological examination of the resected sentinel lymph nodes (SLNs). Elective neck dissection was performed during the same surgical procedure of primary tumor resection when malignant deposits were detected microscopically.

Introduction: To evaluate the enamel abrasion effects of soft, ultra-soft, and nano-bristle toothbrushes using atomic force microscopy (AFM) to guide toothbrush selection for optimal enamel preservation.
Methods: This in vitro study involved 45 extracted human teeth (central and lateral incisors), randomly assigned to three groups (n=15 each): Group I (nano-bristle), Group II (ultra-soft bristle), and Group III (soft bristle). Each specimen underwent 10,000 brushing cycles with a standardized 2 N force to simulate one year of brushing.

Background: Rhabdomyosarcoma (RMS), a rare malignant tumor, frequently affects pediatric patients, with 35%-40% occurring in the head and neck. This study analyzes the clinicopathologic profile of pediatric head and neck rhabdomyosarcomas from Brazil, Guatemala, Mexico, and South Africa.
Methods: We reviewed 44 cases from 10 Oral and Maxillofacial Pathology services, conducting immunohistochemical analyses of desmin, myogenin, Myo-D1, and Ki67, with quantification via QuPath software.

Purpose: To examine the impact of placing plain and impregnated retraction cords for two different retraction times on the postoperative gingival margin level and periodontal health.
Materials And Methods: A total of 40 endodontically treated mandibular first molars were selected and randomly allocated into four groups (n = 10/group); A: plain retraction cord for 10 min, B: plain retraction cord, 20 min, C: impregnated (25% aluminum chloride (AlCl) retraction cord, 10 min, D: impregnated retraction cord (25% AlCl), 20 min. Intraoral digital scans were acquired, and periodontal parameters (Plaque index [PI], Bleeding on probing [BOP], and probing depth [PD]) were assessed at baseline, 7 days, and 28 days after retraction.
