A computer-implemented method of determining the eruption status and tooth type of a target tooth, the method comprising: gathering a three-dimensional model of a patient's dentition including the target tooth, wherein gathering the 3D model comprises one or more of: taking the 3D model of the patient's dentition, receiving the 3D model of the patient's dentition from an intraoral scanner and receiving the 3D model from a scan of a mold of the patient's dentition (190, 200, 201); identifying a portion of the 3D model of the patient's dentition corresponding to the target tooth by segmenting the 3D model of the patient's dentition (193, 204, 205, 207), the portion of the 3D model of the patient's dentition being associated with one or more visual attributes of the target tooth; standardizing the 3D model of the patient's dentition including the target tooth by obtaining surface features representing the shape of each tooth (192, 204, 209); receiving a request to identify the one or more tooth eruption indicators of the target tooth, wherein principal component analysis, PCA, is performed in response to the request; identifying one or more PCA features of a portion of the 3D model of the patient's dentition corresponding to the target tooth, the one or more PCA features being correlated with the surface features of the target tooth (193, 206); determining one or more tooth eruption indicators of the target tooth using the one or more PCA features by comparing the one or more PCA features with one or more PCA features of a 3D model of one or more representative teeth (194, 208, 217), and/or using a machine-trained classifier to recognize one or more of an eruption status and a tooth type of the target tooth based on one or more PCA features of a 3D model of one or more representative teeth (164, 184), wherein the one or more tooth eruption indicators providing a basis to identify an eruption permanentness status of the target tooth, wherein the permanentness status designates whether the target tooth is a permanent tooth or a primary tooth (194, 208, 217); and outputting the one or more tooth eruption indicators corresponding to one of: a primary erupted tooth, a permanent partially erupted or un-erupted tooth, and a permanent erupted tooth (195, 210, 219). gathering a three-dimensional model of a patient's dentition including the target tooth, wherein gathering the 3D model comprises one or more of: taking the 3D model of the patient's dentition, receiving the 3D model of the patient's dentition from an intraoral scanner and receiving the 3D model from a scan of a mold of the patient's dentition (190, 200, 201); identifying a portion of the 3D model of the patient's dentition corresponding to the target tooth by segmenting the 3D model of the patient's dentition (193, 204, 205, 207), the portion of the 3D model of the patient's dentition being associated with one or more visual attributes of the target tooth; standardizing the 3D model of the patient's dentition including the target tooth by obtaining surface features representing the shape of each tooth (192, 204, 209); receiving a request to identify the one or more tooth eruption indicators of the target tooth, wherein principal component analysis, PCA, is performed in response to the request; identifying one or more PCA features of a portion of the 3D model of the patient's dentition corresponding to the target tooth, the one or more PCA features being correlated with the surface features of the target tooth (193, 206); determining one or more tooth eruption indicators of the target tooth using the one or more PCA features by comparing the one or more PCA features with one or more PCA features of a 3D model of one or more representative teeth (194, 208, 217), and/or using a machine-trained classifier to recognize one or more of an eruption status and a tooth type of the target tooth based on one or more PCA features of a 3D model of one or more representative teeth (164, 184), wherein the one or more tooth eruption indicators providing a basis to identify an eruption permanentness status of the target tooth, wherein the permanentness status designates whether the target tooth is a permanent tooth or a primary tooth (194, 208, 217); and outputting the one or more tooth eruption indicators corresponding to one of: a primary erupted tooth, a permanent partially erupted or un-erupted tooth, and a permanent erupted tooth (195, 210, 219).
