NCT03735394

Brief Summary

This clinical study consists on taking 2 different records of the upper and lower incisors area : 1) a perpendicular x-ray and 2) an ultrasonic measurement of gingival thickness on the labial plate. Both measurements are used in order to measure gingival and bone thickness. The aim was to verify the reliability of the tissue measurements of an ultrasonic technique compared with the radiographic technique and to verify whether the biotype has correlation between the maxillary and mandibular biotype in the same patient.

Outcome Measures

Primary Outcomes (1)

  • compare between maxilla and mandibular biotype measured with the periodontal probe

    Classify all patients into one of the three established categories (A1, A2, B) with the aid of a periodontal probe, and compare within the same patient if the biotype of maxilla and mandible is the same or it differs

    1 day

Secondary Outcomes (2)

  • Differences in tissue thickness according to gender

    1 day

  • thickness biotype differences

    1 day

Study Arms (1)

Gingival Biotype

EXPERIMENTAL

A Periodontal probe was used to differentiate between thick and thin biotypes and patients were classified into 3 possible categories of Gingival Biotype (A1, A2 and B) according to Müller \& Eger (https://doi.org/10.1034/j.1600-051x.2000.027009621.x). On each group two measurements were taken on the most protruded lower and upper central incisor: 1/ a tangential radiographic film and 2/ an ultrasonic probe measurement with the PIROP Biometric scanner (G-scan) form Echoson

Diagnostic Test: ultrasonic probe

Interventions

ultrasonic probeDIAGNOSTIC_TEST

apply the head of the ultrasonic probe on the keratinized tissue of the most protruded upper and lower central incisor in order to measure tissue thickness.
