It is of interest to compile available information on the root canal morphology of primary maxillary molars from known literature. The literature resources used to collect data include Medline/PubMed, The Cochrane Central Register of Clinical Trials, SIGLE and Science Direct. Data consists of type of population, number of teeth per study, number of root canals, canal length and type of root canal configuration. We used data from a total of 13 studies (951 primary maxillary molars). Maxillary molars (1st and 2nd) are dominant for two roots variant. The first molar the mean root length ranges from 7.9mm - 8.1mm. The second molar ranges from 7.2mm-8.5mm. Type I (explain in a phrase) canal morphology is the common variant in both the molars. Data shows that Root Canal morphology shows variations with the diagnostic aid (example micro CT) used and in different ethnic populations.
从已知文献中汇编有关乳牙上颌磨牙根管形态的现有信息很有意义。用于收集数据的文献资源包括Medline/PubMed、Cochrane临床试验中央注册库、SIGLE和Science Direct。数据包括人群类型、每项研究的牙齿数量、根管数量、根管长度和根管形态类型。我们使用了总共13项研究（951颗乳牙上颌磨牙）的数据。上颌磨牙（第一和第二）在双根变异中占主导地位。第一磨牙的平均根长范围为7.9毫米至8.1毫米。第二磨牙的范围为7.2毫米至8.5毫米。I型（用一个短语解释）根管形态是两种磨牙中常见的变异。数据表明，根管形态会因使用的诊断辅助工具（例如显微CT）以及不同种族人群而有所变化。
