Heterodonty in the teeth of the turiasaurian sauropod from Angeac‐Charente (Early Cretaceous, southwestern France): Comparison of anatomical and geometric morphometric approaches

open access: yesJournal of Anatomy, EarlyView.
Turiasaurian teeth from Angeac‐Charente exhibit five dental morphotypes and reveal clear heterodonty and anteroposterior size gradient. Qualitative comparative anatomy quickly and efficiently identifies morphotypes, while 3D geometric morphometrics combined with machine learning refine ambiguous cases, demonstrating that qualitative and quantitative ...

Decompression for Unerupted Primary Mandibular Second Molars Associated with Physical Barriers: Case Reports

open access: yes, 2018
Primary impaction of primary teeth might be due to genetic predisposition or physical disturbance including odontoma, supernumerary tooth, and crowded tooth. Among them, calcific deposit or odontoma is commonly associated with primary dentition.

Maxillary dentigerous cyst and supernumerary tooth. Is it a frequent association? [PDF]

open access: yes, 2015
Dentigerous cysts, also known as follicular cysts, are a relatively common pathology in our field. They are associated with unerupted or semi-erupted teeth and are usually not related to supernumerary teeth. OBJECTIVE: To describe a dentigerous cyst case
