About this trial

This is an interventional treatment trial for Gingival Recession focused on measuring Gingival recession, Free gingival graft, Connective tissue graft

Eligibility Criteria

18 Years - 99 Years (Adult, Older Adult)All SexesAccepts Healthy Volunteers

Inclusion Criteria:

  • ASA type I and II subjects
  • Localized Gingival Recessions
  • Recessions Cairo RT I-II-III
  • FMPS < 10%
  • FMBS< 10%
  • <10 cigs/ day

  • Patient is able to give inform consent

Exclusion Criteria:

  • Infection (local or systemic). Each infection will be evaluated prior to study procedure for suitability. Patients with gingivitis or local infection (fracture, apical reaction) will undergo a dental treatment prior to entering the study. In case of systemic infection, the evaluation will be based on medical anamneses, and if necessary will be referred to relevant medical tests.

  • Alcoholism or chronically drug abuse
  • Smokers, ≳ 10 cigarettes per day
  • Immunocompromised patients
  • Uncontrolled diabetes
  • Untreated periodontitis
  • History of previous periodontal surgery (mucogingival or other) on the teeth to be included
  • Presence of severe tooth malposition, rotation or significant version of the tooth to be treated
  • Conditions or circumstances, in the opinion of the investigator, which would prevent completion of study participation or interfere with analysis of study results, such as history of no-compliance or unreliability

Outcomes

Primary Outcome Measures

Digital mean root coverage
Defined as the percentage of root coverage in the mid-buccal aspect, taking baseline as a reference. Measured by dividing the mean surface (in mm²) of the root covered by the procedure by the mean surface (in mm²) of root exposed at baseline.

Primary Outcome Measure Information:
Title
Digital mean root coverage
Description
Defined as the percentage of root coverage in the mid-buccal aspect, taking baseline as a reference. Measured by dividing the mean surface (in mm²) of the root covered by the procedure by the mean surface (in mm²) of root exposed at baseline.
Time Frame
Baseline, 3 months, 6 months and up to 10 years after surgery
Other Pre-specified Outcome Measures:
Title
Complete root coverage
Description
Defined as the presence/absence of complete coverage of the recession at the mid-buccal aspect. It will be evaluated by taking the CEJ as a reference line, at the different timepoints.
Time Frame
Baseline, 3 months, 6 months and up to 10 years after surgery
Title
Mean root coverage
Description
defined as the percentage of root coverage in the mid-buccal aspect, taking baseline as a reference. The MRC equals to the linear distance (in mm, using a probe) between the mid buccal point of the CEJ and the mid-buccal sulcus at baseline, divided by the distance between the mid buccal point of the CEJ and the mid buccal sulcus. The MRC will be measured as percentage (%)
Time Frame
Baseline, 3 months, 6 months and up to 10 years after surgery
Title
Keratinized tissue height
Description
Defined as the linear height of keratinized tissue, measured between the mid-buccal sulcus of the treated tooth and the muco-gingival junction (in mm using a probe). It will be measured at baseline and at the different timepoints.
Time Frame
Baseline, 3 months, 6 months and up to 10 years after surgery
Title
Recession reduction
Description
defined as the linear reduction in recession (in mm using a probe), at the mid buccal aspect, between baseline and the different timepoints.
Time Frame
Baseline, 3 months, 6 months and up to 10 years after surgery
Title
Gingival thickness
Description
evaluated at baseline using couloured paperpoints inserted into the sulcus.
Time Frame
Baseline, 3 months, 6 months and up to 10 years after surgery
Title
CAL
Description
defined as the change in Clinical Attachement of the gingival margin, measured linearly at the mid-buccal aspect, from the JEC to the bottom of the pocket, at the different timepoints.
Time Frame
Baseline, 3 months, 6 months and up to 10 years after surgery
Title
PPD changes
Description
defined as the change in depth of the pocket, measured at the mid-buccal aspect using a probe, between baseline and the different timepoints. It will be measured at the different timepoints.
Time Frame
Baseline, 3 months, 6 months and up to 10 years after surgery
Title
Dental hypersensitivity
Description
Assessed by 10 s air spray applied to the buccal cervical area (yes/no).
Time Frame
Baseline, 3 months, 6 months and up to 10 years after surgery
Title
Root coverage esthetic score
Description
Evaluated at the different timepoints according to Cairo et al. (2009).
Time Frame
Baseline, 3 months, 6 months and up to 10 years after surgery
Title

Description
Biological complications reported by the investigators
Time Frame
Baseline, 3 months, 6 months and up to 10 years after surgery
Title
Digital complete root coverage
Description
defined as the presence/absence of complete coverage of the recession at the mid-buccal aspect. It will be evaluated by taking the CEJ as a reference line, at the different timepoints, analyzed digitally
Time Frame
Baseline, 3 months, 6 months and up to 10 years after surgery
Title
Digital recession reduction
Description
defined as the reduction in recession (in mm², measured digitally), at the mid buccal aspect, between baseline and the different timepoints. It will be measured at the different timepoints.
Time Frame
Baseline, 3 months, 6 months and up to 10 years after surgery
Title
Digital Keratinized Tissue Height
Description
Defined as the changes in keratinized tissue surface (surface delimited mesio-distally by the perpendicular projection of a line passing by the contact-point and apico-coronally by the muco-gingival junction and the gingival margin, at the mid-buccal aspect of the tooth.
Time Frame
Baseline, 3 months, 6 months and up to 10 years after surgery
Title
Digital gingival soft tissue profile
Description
Defined as the change in gingival soft tissue thickness between baseline and the different timepoints, measured at the mid buccal aspect, between baseline and the different timepoints.
Time Frame
Baseline, 3 months, 6 months and up to 10 years after surgery
