Evaluation of Two Resin Composites and Two Adhesives for a Novel Restorative Protocol to Treat Cervical Lesions
Dental Abrasion, Gingival Recession, Composite Resins
About this trial
This is an interventional treatment trial for Dental Abrasion
Eligibility Criteria
Inclusion Criteria:
- Individuals presenting one or more combined defect, i.e. a NCCL classified as B+ (Pini-Prato et al., 2010): presenting more than 1mm in depth, affecting dental crown and root associated with Miller's class I or II gingival recession in canines or premolars with pulp vitality;
- Healthy patients (systemically and periodontally), 18 years old, with at least 20 teeth in occlusion;
- Plaque index ≤ 20% (Ainamo & Bay, 1975);
- NCCL cavo-surface margin without involvement of more than 50% of enamel;
- In tooth included in the study and the adjacent elements of the following must be observed: probing depth less than 3 mm; do not show bleeding on probing (periodontal health) and no insertion loss in the proximal and palatal areas; Provide formal consent to participate in research, after the explanation of the risks and benefits by an individual not involved in it (Resolution #196 October 1996 and the Code of Dental Professional Ethics - C.F.O. - 179/93).
Exclusion Criteria:

Nanofilled Composite - Filtek Z350 XT® - 3M ESPE (NF) + Total Etch adhesive - Adper Single Bond 2® - 3M ESPE (TE) adhesive: combined lesions will be treated with partial restoration with nanofilled resin composite and total-etch adhesive system (two step). Subsequently, periodontal surgery will be performed for root coverage.
Nanofilled Composite - Filtek Z350 XT® - 3M ESPE (NF) + Universal Adhesive - Single Bond Universal® - 3M ESPE (UA): combined lesions will be treated with partial restoration with nanofilled resin composite and one-step self-etching adhesive system. Subsequently, periodontal surgery will be performed for root coverage.
Micro-Hybrid Composite - Charisma Classic® - Heraeus Kulzer (MH) + Total Etch adhesive - Adper Single Bond 2® - 3M ESPE (TE) adhesive: combined lesions will be treated with partial restoration with micro-hybrid resin composite and total-etch adhesive system (two step). Subsequently, periodontal surgery will be performed for root coverage.
