Diagnosis attitudes and restorative practices of non-carious cervical lesions by a group of Brazilian dentists from the state of Rio de Janeiro

Abstract

This study aimed to identify diagnosis and restorative practices of non-carious cervical lesions (NCCLs) by a group of Brazilian dentists from the State of Rio de Janeiro. After ethical approval, a questionnaire was sent for a group of dentists registered at the Regional Council of Dentistry of the State of Rio de Janeiro (CRO-RJ, Brazil) and the answers were collected in a period of 15 days. The questionnaire considered training experience and attendance profile, diagnostic attitudes and restorative practices for direct restorations of NCCLs. The data were presented in a descriptive way and Chisquare tests (95% significance) were used to verify possible relations between dentists training/attendance profiles and NCCLs diagnosis/restorative attitudes. Most part of dentists considered the etiology as multifactorial and seek to distinguish the different types of NCCL, but only a minority respond to use auxiliary methods for diagnosis. Cotton-roll is the most used method for moisture control and 51.6% do not use gingival retraction/separation techniques. Two-step total-etch adhesive systems and hybrid/ microhybrid composite resins were the most commonly refereed materials for direct restorations. Only 8.3% considered that restorations can last for a period of more than 5 years in clinical service. There was significant relation between remuneration and the type of isolation (p = 0.038) and also with gingival retraction/separation techniques (p = 0.043). It can be concluded that (a) the majority of the respondents revealed to seek distinguishes among the different types of NCCLs, but only a minority use auxiliary methods to diagnosis; (b) the form of remuneration influence the attitudes regarding the isolation method; (c) the two-step total-etch adhesive systems are the most used to restore NCCLs, (d) and that for the most part of the respondents the restorations of NCCLs made with resin composites do not last for more than 5 years.

Stereomicroscopic Aspects of Non-Carious Cervical Lesions

“…In some cases, they are a necessity due to teeth sensitivity, physiognomic disturbances and even dental fractures in an advanced stage [7,12,13]. The marginal degradation of restorations is frequently observed over time [9] so that they do not last more than 5 years [14], with occlusal overloads having an essential role in the progression of NCCLs [6,15,16].…”

Non-silicate nanoparticles for improved nanohybrid resin composites

“…Better adhesives and improved restorative techniques were developed concurrently. Today, micro/nanohybrid resin composites are considered the gold standard materials for direct restorations [5][6][7][8]. Since fractures are one of the most reported reasons for failure of restorations [5][6][7], it seems that there is still room for improvement in mechanical performance of dental resin composites.…”
