Molar shape variability in platyrrhine primates.
Nova Delgado M, et al. J Hum Evol 2016. PMID 27650581
The aim of this study was to assess molar shape variability in platyrrhines, to explore patterns of interspecific variation among extant species, and to evaluate how molar shape can be used as a taxonomic indicator. ...Our results show that the phylogenetic and functional signals of lower molar shape vary depending on the taxa and the tooth considered. ...

Factors associated with spontaneous angular changes of impacted mandibular third molars as a result of second molar protraction.
Baik UB, et al. Am J Orthod Dentofacial Orthop 2019. PMID 31375227
Regression analyses were used to identify significant factors related to third molar uprighting. RESULTS: Nolla stage (odds ratio [OR] 4.1), sex (OR 0.003 for male), third molar angulation at T1 (OR 1.1), missing tooth space (OR 0.006), rate of third molar eruption (OR 23.3), and rate of second molar protraction (OR 0.2) significantly affected third molar uprighting. Age, third molar angulation at T1, rate of third molar eruption, and rate of second molar protraction were significant factors for predicting third molar angulation at T2. ...

A longitudinal study on timing and velocity of rat molar eruption: Timing of rat molar eruption.
Denes BJ, et al. Lab Anim 2018. PMID 29316852
Rat molar eruption and occlusion data were compiled from several studies but several inconsistencies were found, rendering the planning of eruptional studies difficult and imprecise. ...The first molar erupts on average on day 17, the second molar on day 20, and the third molar on day 33. The eruption velocity of the first molar was the highest at 90.9 microns/day (standard error (se) = 12.80), followed by the second molar at 65.9 microns/day (se = 5.80), and the lowest was the third at 47.0 microns/day (se = 3.28), ( p < 0.001). ...

Middle Mesial and Middle Distal Canals in Mandibular First Molar.
Jabali AH. J Contemp Dent Pract 2018. PMID 29422476
AIM: The aim of this article is to report on the successful treatment and follow-up of mandibular first molar with additional middle mesial (MM) and middle distal (MD) canals. ...CLINICAL SIGNIFICANCE: Mandibular first molar with six canals is very rare to encounter. Clinician should have a thorough knowledge of these unusual anatomy to avoid treatment failure due to incomplete disinfection of the root canal system....

Ectopic Eruption of the Permanent Maxillary First Molar: Predictive Factors for Irreversible Outcome.
Dabbagh B, et al. Pediatr Dent 2017. PMID 28583246
Increased magnitude of impaction, degree of resorption of the primary second molar, severe lock, and bilateral occurrence were positively correlated with irreversible EE. ...

Evo-devo models of tooth development and the origin of hominoid molar diversity.
Ortiz A, et al. Sci Adv 2018. PMID 29651459 Free PMC article.
Despite the prominence of molar form in human origins research, the underlying developmental mechanisms generating the diversity of tooth crown features remain poorly understood. ...Our results have implications for the accurate interpretation of molar crown configuration in hominoid systematics....

Mechanics analysis of molar tooth splitting.
Barani A, et al. Acta Biomater 2015. PMID 25584989 Free article.
A model for the splitting of teeth from wedge loading of molar cusps from a round indenting object is presented. The model is developed in two parts: first, a simple 2D fracture mechanics configuration with the wedged tooth simulated by a compact tension specimen; second, a full 3D numerical analysis using extended finite element modeling (XFEM) with an embedded crack. ...

Impact of wear and diet on molar row geometry and topography in the house mouse.
Renaud S and Ledevin R. Arch Oral Biol 2017. PMID 28463690
RESULTS: The geometry of the molar rows was heavily affected by age-related wear. Food consistency affected mostly the upper molar row, which was more worn and less helical in soft food eaters. ...Tooth relief was lower in soft food eaters, but only on the upper molar row. Tooth complexity was insensitive to wear. CONCLUSION: The primary factor affecting tooth geometry and topography is age-related wear, as wear erodes the molar surfaces. ...

Microscopic analysis of molar--incisor malformation.
Lee HS, et al. Oral Surg Oral Med Oral Pathol Oral Radiol 2015. PMID 25544405
OBJECTIVE: Molar-incisor malformation (MIM) is a newly discovered type of dental anomaly that involves a characteristic root malformation of the permanent first molars. ...

Efficiency of molar distalization associated with second and third molar eruption stage.
Flores-Mir C, et al. Angle Orthod 2013 - Review. PMID 23167519
OBJECTIVE: To evaluate the efficiency of molar distalization associated with the second and third molar eruption stage. MATERIALS AND METHODS: A systematic computerized database search was conducted using several databases. ...CONCLUSION: The effect of maxillary second and third molar eruption stage on molar distalization-both linear and angular distalization-appears to be minimal. ...
