Uprighting a Mesially Partial Impacted Mandibular Second Molar: A Case Report [PDF]

Iranian Journal of Orthodontics, 2006
Impaction of the lower second molar is not a common problem (0.03%), but it is very challenging for orthodontists. Unilateral mandibular second molar impaction is the most popular form of second molar impactions.

Reln mRNA Delivery Drives Neurogenic Bone Regeneration by Orchestrating Schwann Cell‐Mediated Exosomal Trafficking

Advanced Science, EarlyView.
MSNs serve as a robust vehicle for CRISPRa‐mediated Reln induction, driving bone repair through the establishment of a neurogenic‐supportive microenvironment. ABSTRACT Neurogenic bone regeneration is essential for the effective restoration of bone tissue functionality, while the mechanisms and new strategies underlying neurogenic bone regeneration ...

The Influence of Mandibular Third Molar Position on Distal Caries in Mandibular Second Molar

Journal of Oral and Dental Research, 2015
Introduction: Distal caries of mandibular second molars has been documented to be associated almost exclusively with impacted third molars. The level of involvement of second molars in distal caries is influenced by the angulation of the occlusal surface of mandibular third molars and third molars depth.

Cortical bone distribution in the human mandibular symphysis: Ontogenic and morphometric approaches in archeological context

The Anatomical Record, EarlyView.
Abstract The human mandibular symphysis concentrates multiaxial loads during function and remodels throughout growth, but the precise mechanisms underlying cortical bone shape during growth remain relatively unexplored. Approaches based solely on thickness or external cortical contours provide only partial insights and do not capture the functional ...

Determination of Cusp Number and Occlusal Groove Pattern in Mandibular Molars: A Preliminary Epidemiological Study in an Indian Population

Journal of Forensic Science and Medicine, 2016
Teeth are excellent material in living and nonliving populations for anthropological, genetic, odontologic, and forensic investigations. The present study aims to study the number of a number of cusps in the first and second mandibular molar and to ...

Redescription of the Triassic cynodont Cistecynodon parvus and reassessment of its phylogeny

The Anatomical Record, EarlyView.
Abstract Cynodontia is an important subclade of Therapsida that first occurred in the late Permian. It includes extinct subclades which are the non‐mammaliaform cynodonts and Mammaliaformes, with the latter ultimately giving rise to crown mammals. The systematics of non‐mammaliaform cynodonts has been extensively studied and is relatively well‐resolved,

Impaction of permanent mandibular second molar: A retrospective study

Medicina Oral Patología Oral y Cirugia Bucal, 2013
To determine the prevalence of impacted mandibular second molar (MM2) and the association between MM2 impaction and crowding. The clinical significance of the angle between first and second mandibular molar and of the space between the first mandibular molar (MM1) and the anterior margin of mandibular ramus in MM2 impaction were also evaluated.In this ...

Early stages of tooth development in the harbor porpoise Phocoena phocoena

The Anatomical Record, EarlyView.
Abstract Here we describe the stages of tooth development in toothed whales on the basis of the harbor porpoise (Phocoena phocoena). The aim of the study was to find out whether these stages are identical to those of other mammals analyzed so far although toothed whales are homodont and monophyodont.

Dental anomalies in Pleistocene African hippopotamuses from Olduvai Bed II

The Anatomical Record, EarlyView.
Abstract Hippopotamuses are key palaeoenvironmental indicators in African Pleistocene ecosystems due to their ecological dependence on permanent water bodies and their frequent representation in the fossil record. This study examines dental anomalies in Hippopotamus cf. gorgops from several localities in Bed II of Olduvai Gorge (Tanzania), dated to ca.
