Aim: The aim of the present study was to investigate the association of Apgar index with that of enamel defects and to explore gender predilection as a co-variable in the formation of enamel defects.
Materials And Methods: A random sample of 108 individuals (46 boys and 62 girls) aged 4-5 years (mean - 4.4 years) were included in the study. A questionnaire containing subject's demographic information, Apgar Index (AI), enamel hypoplasia and hypocalcification was collected. Intraoral examination of the subjects was performed by using the type III diagnostic criteria recommended by WHO for oral health surveys. According to the modified index for developmental enamel defects, visual and tactile examinations of the entire primary dentition were performed.The data obtained was analysed using chi-square test.
Results: Of all the examined individuals 18 (16.7%) showed enamel defects, of which 10 (9.3%) were having enamel hypoplasia, 4 (3.7%) were having enamel hypocalcification and 4 (3.7%) were having both. Correlation of the enamel defects such as hypoplasia, hypocalcification and both had no significant relationship with the gender (P = 0.36).
Conclusion: Subjects with lower Apgar Index exhibited more hypoplastic and hypocalcified teeth both qualitatively and quantitatively. If the Apgar value is less than 6, the vulnerability for the development of enamel defects has considerably increased. Gender of the individuals did not influence the final outcome.

Aim: To assess the prevalence of tooth-related, soft tissue, and intraosseous pathologies in the pediatric population (0-17 years) in a South Indian dental teaching institution and to compare the results with previous literature.
Materials And Methods: Clinical data from the pedodontics department and histopathological records from the oral pathology department were analyzed from the year 2010 to 2022 and grouped into two major categories: group I, abnormalities of teeth, and group II, intraosseous and mucosal/soft tissue lesions. The data were entered into a Microsoft Excel spreadsheet, and descriptive analysis was conducted using Statistical Package for the Social Sciences (SPSS) software, version 26.

Background: Celiac disease (CD) is a systemic disorder characterized by an enteropathy of highly variable clinical expression, in which the relationship with oral pathology has not yet been fully elucidated. We aimed to update the current knowledge on oral manifestations in CD, to identify evidence gaps and to point out future research lines.
Material And Methods: PRISMA-ScR guidelines were followed.

Molar incisor hypomineralization (MIH) is a developmental defect that affects the enamel tissue of permanent teeth. Clinicians may observe a range of opacities in the affected teeth, varying from white to creamy, yellow, and brown. Of particular interest is an etiology of MIH that has not been rigorously elucidated.

Objectives: Calcium ions (Ca) play crucial role in tooth development, particularly in maintaining enamel density during amelogenesis. Ameloblasts require specific proteins such as amelogenin, ameloblastin, enamelin, kallikrein, and collagen for enamel growth. Recent research has highlighted the importance of calcium and fluoride ions, as well as the TRPM7, STIM, and SOCE pathways, in regulating various stages of enamel formation.

A dentigerous cyst (DC) is the most common developmental cystic lesion of the jaws. Histologically, these cysts derive from the odontogenic epithelium that includes the reduced enamel epithelium, epithelial cell rests of Serres, and epithelial cell rests of Malassez. Radiographically, DCs are usually presented as well-defined radiolucencies associated with the crown of an unerupted tooth at the level of the cementoenamel junction (CEJ).
