Literature review and micro-computed tomography analysis of natal teeth: A pilot study
Aim
To outline the current literature surrounding natal teeth, and then, in a pilot study, to evaluate natal teeth using micro-computed tomography (micro-CT) to determine their anatomical profile, and compare and contrast different analytical methods to assess natal teeth.
Methods
2 extracted natal teeth (mandibular central incisors) and 1 exfoliated mandibular primary central incisor were subjected to micro-CT analysis.
Results
Within natal teeth, there were no statistical differences in tooth mineral density (TMD) of both enamel and dentine (P > .05), whereas mandibular primary central incisors had a significantly higher TMD of both enamel and dentine in comparison with both natal tooth 1 and natal tooth 2 (P < .05). Mandibular primary central incisors had a greater thickness and volume of both enamel and dentine, but exhibited lower pulpal space volume.
Conclusion
Micro-CT is an alternative and non-invasive method to anatomically assess natal teeth. According to the pilot study, natal teeth exhibited lower TMD, decreased enamel and dentine thickness, and smaller pulpal space volume in comparison with mandibular primary incisor teeth. This pilot study creates a foundation to establish the collection and analysis of natal teeth on a larger scale over time using micro-CT.
期刊介绍：
Journal of Investigative and Clinical Dentistry (JICD) aims to publish quality, peer reviewed original research and topical reviews on all aspects of investigative and clinical dentistry and craniofacial research, including molecular studies related to oral health and disease. Although international in outlook, the Editor especially encourages papers from the Asia Pacific. The journal also aims to provide clinicians, scientists and students of dentistry with a knowledge transfer platform for rapid publication of reports through an international journal, which will be available free online until 2012. Its scope, therefore, is broad, inclusive and international, but with a particular focus on Asia Pacific. The Editor welcomes manuscripts in the following key thematic areas in oral and maxillofacial sciences: Community Dentistry and Oral Epidemiology, Conservative Dentistry, Dental Biomaterials, Dental Pedagogy, Endodontics and Traumatology, Implant Dentistry, Oral Biosciences, Oral and Maxillofacial Surgery, Oral Medicine, Oral Pathology and Oral Microbiology, Orthodontics, Oral Radiology, Oral Rehabilitation, Paedodontics, Periodontology and Periodontal Medicine.
