Early synapsids neurosensory diversity revealed by CT and synchrotron scanning

The Anatomical Record, EarlyView.
Abstract Non‐mammaliaform synapsids (NMS) represent the closest relatives of today's mammals among the early amniotes. Exploring their brain and nervous system is key to understanding how mammals evolved. Here, using CT and Synchrotron scanning, we document for the first time three extreme cases of neurosensory and behavioral adaptations that probe ...

Risk prediction model of impacted supernumerary tooth-associated root resorption in children based on cone-beam computed tomography analysis: a case control study

BMC Oral Health
Background External surface resorption is pressure-induced resorption and occurs on the external surface of the root, pressure exerted by impacted teeth, is common causes of external surface resorption.

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

, 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

Dental anomalies inside the cleft region in individuals with nonsyndromic cleft lip with or without cleft palate [PDF]

, 2015
Background: Individuals with nonsyndromic cleft lip with or without cleft palate (NSCL±P) present high frequency of dental anomalies, which may represent complicating factors for dental treatment.

Integrating mandibular evidence to assess morphological variation of the Australopithecus afarensis maxilla

The Anatomical Record, EarlyView.
Abstract Geometric morphometric analyses are used to explore variation of maxillary dental arcades of Australopithecus afarensis, expanding on the work of Hanegraef and Spoor, 2025 (Morphological variation of the Australopithecus afarensis maxilla.

Frequency of mesiodens in the pediatric population in North India: A radiographic study. [PDF]

, 2013
Objectives: Mesiodens are the most common supernumerary teeth, occurring in 0.15% to 2.2% of the population. The aim of the present study was to analyze the frequency and radiological features of mesiodens in the pediatric population.

Algorithm for Treatment of Supernumerary Nasal Tooth

Journal of Craniofacial Surgery, 2021
Abstract The presence of a tooth in the nasal cavity is a rare condition. There is an even more rare association, which is the presence with the mineral's deposition and formation of rhinoliths. This report shows a case of rare nasal tooth associated with rhinolithiasis and describes its surgical treatment based on an algorithm.

A detailed redescription of a skeletally immature ‘Redondasaurus’ suggests ontogenetic transformations in the taxon mirror phytosaurian morphological evolution

The Anatomical Record, EarlyView.
Abstract The study of morphological evolution is fundamentally tied to ontogeny, yet studies of these heterochronic processes in the fossil record are rare. Fossils belonging to an ontogenetic series are difficult to assign to an ontogenetic stage due to inconsistent proxies for skeletal ages, challenging to taxonomically assign due to morphological ...

FAM20B-catalyzed glycosaminoglycans control murine tooth number by restricting FGFR2b signaling

BMC Biology, 2020
Background The formation of supernumerary teeth is an excellent model for studying the molecular mechanisms that control stem/progenitor cell homeostasis needed to generate a renewable source of replacement cells and tissues.
