Scope of Research

The Craniofacial Biology (CB) Research Laboratory studies the growth, development and function of the masticatory system. Work at this center focuses on craniofacial deformity and asymmetry, temporomandibular disorders (TMD), and orthodontic and surgical treatment outcomes related to malocclusion. 

Research is characterized by classic scientific approaches for the genotype-phenotype basis of human diseases, while ongoing efforts are strengthened by diagnostic breakthroughs in the understanding of subclassifications of craniofacial asymmetry. The CB research laboratory leads the field in identifying links between craniofacial asymmetry and TMD, as well as determining whether treatment alleviates or worsens malocclusion-associated conditions.

The facility comprises a 780-square-foot renovated laboratory space outfitted with freezers, microcentrifuges, scales and thermal cyclers for polymerase chain reaction.

Scientific techniques include the following.

  • Clinical diagnosis and treatment outcomes
  • Gene expression
  • Genotyping and geometric morphometrics
  • Muscle physiology

The CB research laboratory is currently exploring potential environmental factors in the development of malocclusion among traditionally underserved North Philadelphia patient populations. A high throughput screening clinic is collecting demographic and phenotypic information on area patients who are seeking standard orthodontic treatment.
