  • Treatment Decision-making of Cracked Teeth: Survey of American Endodontists. [Journal Article]
    J Contemp Dent Pract 2019; 20(5):543-547Abulhamael AM, Tandon R, … Rotstein I
  • CONCLUSIONS: It appears that the presence of a 6-mm periodontal pocket is considered an important factor by most American endodontists when deciding whether to preserve the cracked tooth or extract it.There is no consensus among dentists regarding the best approach to treat cracked teeth. Conclusive studies evaluating clinical approaches of endodontists regarding treatment of cracked teeth are lacking. Therefore, surveyed opinion of endodontists in the United States regarding their approach to treatment of cracked teeth was done to try to reach the best clinical decision regarding this dilemma.
  • Microcomputer tomography measurement of minimum residual dentin thickness in mandibular first molars after virtual fiber post placement. [Journal Article]
    J Prosthet Dent 2019Chen X, Min Y, … Peng L
  • CONCLUSIONS: For post placement in endodontically treated mandibular first molars, using a larger-sized post decreased the RDT and increased the perforation rate. Small fiber posts were safer and prevented perforation, with the distal root being the first choice. If more posts are required in a mesiobuccal and mesiolingual canal, the smallest appropriately sized post should be placed less than 3 mm from the root canal orifice. Combining virtual fiber post placement performed using a framework based on MeVisLab with μ-CT scanning is a convenient and accurate method of evaluating the risk of canal wall perforation.
  • Variation of 3D outer and inner crown morphology in modern human mandibular premolars. [Journal Article]
    Am J Phys Anthropol 2019; 169(4):646-663Krenn VA, Fornai C, … Weber GW
  • CONCLUSIONS: Due to marked intragroup and intergroup variation in GM analyses of lower premolars, discrete traits such as the number of lingual cusps and mesiolingual groove expression provide better geographic separation of modern human populations. The greater variability of the lingual region suggests a dominance of functional constraints over geographic provenience or sex. Additional information about functionally relevant aspects of the crown surface and odontogenetic data are needed to unravel the factors underlying dental morphology in modern humans.
