Abstract: According to an embodiment, a method for generating a digital three-dimensional model representing development in dental condition for a tooth is disclosed. The method includes obtaining, at different timepoints, a first digital 3D model of a patient's set of teeth including first texture data and a second digital 3D model of the patient's set of teeth including second texture data. The first digital 3D model including the first texture data and second digital 3D model including the second texture data are placed in a common texture space by uniformizing texture. Lastly, the digital three-dimensional model representing development in dental condition is generated based on a comparison of the first texture data and the second texture data of corresponding regions in the first digital 3D model and the second digital 3D model placed in the common texture space.

Abstract: According to an embodiment a computer-implemented method for detecting dental plaque on a digital 3D model (101) of a dental situation is disclosed. The method comprises receiving, by a processor, the digital 3D model (101) of the dental situation, providing at least a part of the digital 3D model (101) as an input (601) to a trained neural network (600), wherein the at least part of the digital 3D model (101) comprises natural color information and/or geometric information associated with at least one tooth surface of the dental situation. The geometric information comprises a curvature information, a facet normal information, a depth information relating to a virtual camera position and/or an angle between a facet normal and a virtual camera direction. Further, the method comprises obtaining an output (605) from the trained neural network (600) based on the provided input (610), wherein the output (605) comprises a dental plaque parameter associated with the at least one tooth surface, assigning the dental plaque parameter to the at least part of the digital 3D model (101) and displaying the digital 3D model (101) with the dental plaque parameter assigned to the at least part of the digital 3D model (101).
