Accurate age estimation is essential for constructing biological profiles in forensic investigations. DNA methylation, particularly in age\u2010related genes such as\n                    <jats:italic>FHL2<\/jats:italic>\n                    , has emerged as a promising epigenetic marker for this purpose. While previous studies have applied methylation assays to the entire tooth, these methods often result in the destruction of the dental structures. In this study, we assessed whether\n                    <jats:italic>FHL2<\/jats:italic>\n                    methylation levels measured using methylation\u2010sensitive high\u2010resolution melting (MS\u2010HRM) in root surface samples could serve as a reliable marker for age estimation in Japanese individuals. Samples were collected from the root surfaces of extracted third molars using one to three strokes with a dental scaler, primarily obtaining cementum or cementum with minor dentin content. MS\u2010HRM analysis was performed using primers previously validated for saliva and blood. The\n                    <jats:italic>FHL2<\/jats:italic>\n                    methylation scores were significantly correlated with chronological age, despite the use of non\u2010fresh samples stored at room temperature. Notably, the methylation levels were unaffected by self\u2010reported coffee consumption and smoking habits. Additionally, while alveolar bone resorption status was associated with both age and methylation scores, it did not alter the strength of this correlation. Although a regression formula derived from\n                    <jats:italic>FHL2<\/jats:italic>\n                    alone yielded low accuracy, these results suggest that root surface methylation data may be valuable for age estimation, particularly when combined with additional genetic markers. This minimally invasive method preserves tooth morphology and may be applicable even in decomposed remains, offering practical advantages in forensic contexts.\n
