Abstract

Aims: This study aimed to investigate the morphology of the palate, palatal rugae pattern, and dental arch form in patients with schizophrenia. 

Methods and results: An observational case-control study was designed following the STROBE statement and checklist. The sample consisted of 132 patients (39 diagnosed with schizophrenia and 93 controls). Dental casts of the patients were classified based on the pattern of their palatal rugae, their dental arch form, and the area of their palate. The palatal rugae in patients with schizophrenia had a more random distribution and shape compared to the control group (P =.027). Oval dental arches were the most prevalent in both groups (P =.473). The palate area was slightly larger in the control group (3.2318 ± 0.549 mm2) compared with the group of patients with schizophrenia (3.060 ± 0.470 mm2) (P =.090). 

Conclusion: Palatal rugae pattern may feature as a potential minor physical anomaly for schizophrenia. Additional studies with alternative sampling and classification systems are necessary to understand this finding and its applications in practice.
