The ADA SNODENT Canvass Committee has approved ANSI/ADA Standard No. 2000.2 for SNODENT (Systemized Nomenclature of Dentistry). The Committee has representation from all interests in the United States in the development of a standardized clinical terminology for dentistry. The Committee has adopted the standard, showing professional recognition of its usefulness in dentistry, and has forwarded it to the American National Standards Institute with a recommendation that it be approved as an American National Standard. The American National Standards Institute granted approval of ADA Standard No. 2000.2 as an American National Standard on December 3, 2018. A standard electronic health record (EHR) and interoperable national health information infrastructure require the use of uniform health information standards, including a common clinical language. Data must be collected and maintained in a standardized format, using uniform definitions, in order to link data within an EHR system or share health information among systems. The lack of standards has been a key barrier to electronic connectivity in healthcare. Together, standard clinical terminologies and classifications represent a common medical language, allowing clinical data to be effectively utilized and shared among EHR systems.

Canger Fusion is a developmental anomaly defined as the union Faculty of Dentistry, Department of Oral and Maxillofacial Radiology of two normally separated tooth buds with the dentins University of Ondokuz Mayis, Turkey at any stage of their development. They may be fused or separated, depending on the development stages of e-mail: [email protected] dental pulp and canal. Tooth gemination is the separation of a single tooth germ. Teeth with large single or bifid crown have a normal root or root canal. As a general rule, when the affected tooth is regarded as one, if in Primary double teeth the arch there is one tooth less than the normal count it is called fusion, while when the normal number of teeth and their effect is present it is termed gemination [Duncan and Helpin, 1987]. However, literature shows that the differential on permanent diagnosis between fusion and gemination is difficult (in some cases, fusion with supernumerary tooth) [Duncan successors and Helpin, 1987; Shafer et al., 1974]. The term “double teeth” is often used to describe both anomalies [Brook and Winter, 1970; Buenviaje and Rapp, 1984; Tasa and Lukacs, 2001]. The prevalence of ABSTRACT double teeth varies between 0.1 and 3% [Duncan and Helpin, 1987; Tasa and Lukacs, 2001].
