Abstract

Introduction

White spot lesions are opaque, chalky white or yellowish discolorations on the surface of teeth that result from the demineralization of the tooth structure. Many methods, including SEM, XRD, and FTIR spectroscopy, are crucial for identifying and evaluating enamel white spot lesions. It is imperative to have a thorough grasp of the morphology, crystallographic structure, mineral composition, and chemical changes associated with enamel white spot lesions.

Method

In vitro lesions were meticulously obtained by immersing extracted teeth in hydrochloric acid for a week and drying them using artificial caries. Characterization investigations were conducted with utmost precision and thoroughness using FTIR, XRD, and SEM, ensuring the reliability and validity of the results.

Results

FTIR analysis revealed the existence of calcium oxide and hydroxyapatite, and SEM examination assisted in identifying differences in surface shape. The enamel's crystalline nature was revealed via XRD investigation.

Conclusion

White spot lesions are associated with the development of deep caries. Advanced imaging strategies are needed for additional validation.

了解釉质白斑病变的空间和地形特征，实现有针对性的再矿化

导言白斑病是牙齿表面不透明、白垩色或淡黄色的色斑，是牙齿结构脱矿的结果。许多方法，包括扫描电子显微镜、X射线衍射和傅立叶变换红外光谱，对于识别和评估釉质白斑病变至关重要。必须全面掌握与釉质白斑病变相关的形态、晶体结构、矿物成分和化学变化。方法将拔出的牙齿在盐酸中浸泡一周，然后用人工龋齿将其烘干，细致地获得体外病变。采用傅立叶变换红外光谱（FTIR）、X射线衍射（XRD）和扫描电子显微镜（SEM）进行表征研究，确保研究结果的可靠性和有效性。结果傅立叶变换红外光谱分析显示存在氧化钙和羟磷灰石，扫描电子显微镜检查有助于确定表面形状的差异。结论白斑病变与深龋的发展有关。需要先进的成像策略来进一步验证。

期刊介绍： Journal of Oral Biology and Craniofacial Research (JOBCR)is the official journal of the Craniofacial Research Foundation (CRF). The journal aims to provide a common platform for both clinical and translational research and to promote interdisciplinary sciences in craniofacial region. JOBCR publishes content that includes diseases, injuries and defects in the head, neck, face, jaws and the hard and soft tissues of the mouth and jaws and face region; diagnosis and medical management of diseases specific to the orofacial tissues and of oral manifestations of systemic diseases; studies on identifying populations at risk of oral disease or in need of specific care, and comparing regional, environmental, social, and access similarities and differences in dental care between populations; diseases of the mouth and related structures like salivary glands, temporomandibular joints, facial muscles and perioral skin; biomedical engineering, tissue engineering and stem cells. The journal publishes reviews, commentaries, peer-reviewed original research articles, short communication, and case reports.
