Study Arms:
- Measurement of the periodontal ligament space (Type: OTHER): Evaluation of the width of the ligament in patients with SSc and comparison to the width found in control.
- Radiographic analysis of oro-facial manifestations (Type: OTHER): Establishment of a complete clinical phenotypic description of oral manifestations associated with SSc and comparison with the control group.
