简要总结

The aim of this study is to assess if there are significant differences in periodontal conditions between patients undergoing fixed orthodontic treatment with stainless steel or ceramic brackets. For this study, patients will be enrolled and divided into two groups, according to the type of brackets (stainless steel or ceramic) used for orthodontic treatment. A professional supragingival and subgingival oral hygiene will be performed before the bonding of the orthodontic brackets together with a periodontal evaluation will be recording the following periodontal indices: PPD, BoP, BS, GI, PI, BEWE and Schiff Air Index. Indices will be recorded after 1, 3 and 6 months after the bonding, separately for both in maxillary and in mandibular dental arches and only for teeth with brackets bonded.

详细描述

This clinical trial aims to investigate if there are significant differences in periodontal conditions between patients undergoing fixed orthodontic treatment with stainless steel or ceramic brackets. Patients recruited for the study will be asked to sign the informed consent. Parents will sign the consent for underage patients. A professional supragingival and subgingival oral hygiene will be performed before the bonding of the orthodontic brackets; a piezoelectric instrument and Gracey curettes will be used. After that, patients will be divided into two groups:

  • Group MET: stainless steel brackets will be bonded on the vestibular surfaces of teeth.
  • Group CER: ceramic brackets will be bonded on the vestibular surfaces of teeth. Before the bonding on maxillary dental arch, a periodontal evaluation will be conducted recording the following periodontal indices: PPD, BoP, BS, GI, PI, BEWE and Schiff Air Index. Indices will be recorded after 1, 3 and 6 months after the bonding, separately for both in maxillary and in mandibular dental arches. Only teeth with brackets bonded will be considered.

结局指标

主要结局

Change in GI - Gingival Index (Loe and Silness, 1963)

时间窗: Before the bonding procedure; after 1, 3 and 6 months after the bonding both in maxillary and in mandibular dental arches

Scoring criteria: * 0 = normal gingiva * 1 = mild inflammation, edema and swelling; no bleeding * 2 = moderate inflammation with edema, swelling and bleeding on probing * 3= severe inflammation with marked edema, redness, tissues, ulceration and spontaneous bleeding

Change in BS - Bleeding Score

时间窗: Before the bonding procedure; after 1, 3 and 6 months after the bonding both in maxillary and in mandibular dental arches

Scoring criteria: * 0 = no bleeding * 1 = punctiform bleeding in the site of probing * 2 = slightly extended bleeding in the site of probing * 3 = bleeding in more than a half of gingival margin * 4= gingival border fully covered by blood

Change in PI - Plaque Index (Silness and Löe, 1964)

时间窗: Before the bonding procedure; after 1, 3 and 6 months after the bonding both in maxillary and in mandibular dental archesBefore the bonding procedure; after 1, 3 and 6 months after the bonding both in maxillary and in mandibular dental arches

Scoring criteria: * 0 = no plaque * 1 = thin plaque layer at the gingival margin, only detectable by scraping with a probe * 2 = moderate layer of plaque along the gingival margin; interdental spaces free, but plaque is visible to the naked eye * 3= abundant plaque along the gingival margin; interdental spaces filled with plaque

Change in PPD - Probing Pocket Depth

时间窗: Before the bonding procedure; after 1, 3 and 6 months after the bonding both in maxillary and in mandibular dental archesBefore the bonding procedure; after 1, 3 and 6 months after the bonding both in maxillary and in mandibular dental arches

Evaluation (in mm) of the depth of the gingival sulcus, through a millimeter periodontal probe; it is detected from the gingival margin to the bottom of the gingival sulcus or periodontal pocket, evaluated at 6 sites.

Change in BEWE index (Basic Erosive Wear Examination)

时间窗: Before the bonding procedure; after 1, 3 and 6 months after the bonding both in maxillary and in mandibular dental archesBefore the bonding procedure; after 1, 3 and 6 months after the bonding both in maxillary and in mandibular dental arches

Scoring criteria: * 0 = no ETW (erosive tooth wear) * 1 = initial loss of surface texture * 2 = distinct defect; hard tissue loss involving \<50% of the surface area * 3 = hard tissue loss involving ≥50% of the surface area

Change in Schiff Air Index - sensitivity score

时间窗: Before the bonding procedure; after 1, 3 and 6 months after the bonding both in maxillary and in mandibular dental archesBefore the bonding procedure; after 1, 3 and 6 months after the bonding both in maxillary and in mandibular dental arches

Evaluation criteria with the visual analog scale (VAS). The patient indicates the pain level on the scale of 0-10

Change in BOP - Bleeding on Probing (percentage)

时间窗: Before the bonding procedure; after 1, 3 and 6 months after the bonding both in maxillary and in mandibular dental archesBefore the bonding procedure; after 1, 3 and 6 months after the bonding both in maxillary and in mandibular dental arches

Site-specific assessment of the presence or absence of gum bleeding after the insertion of the periodontal probe. Percentage of sites with bleeding on probing determines the BOP%.
