Treatment of non-carious lesions: Diagnosis, restorative materials and techniques

Abstract

Management of non-carious cervical lesions (NCCLs) still is a challenge in clinical practice. The diagnosis is the key to treat these lesions successfully. Aim/Case report: Therefore, the aim of this case report is to describe the diagnosis and treatment of generalized abfraction lesions associated to abrasion lesions of a 43 years old patient and to discuss considerations about the technique and materials to be used appropriately. After the diagnosis, a treatment plan with preventive and restorative approach was elaborated. The occlusal adjustment was performed to distribute the contact points and the patient was instructed in relation to tooth brushing habits. It was also recommended that the patient use a dentifrice with potassium nitrate for the control of sensitivity. For lesions over 1mm deep, the restorative treatment was performed using the self-etching adhesive system and nanohybrid composite by the stratification technique. Unsatisfactory restorations have been replaced. Occlusal splint was done and the patient was instructed to use the device every day overnight. One year after treatment, follow-up was performed. The appearance of new NCCLs was not observed. There was no progression of lesions smaller than 1 mm. There was no loss of restorations. All restorations were fully satisfactory and the patient reported absence of dentin hypersensitivity. Conclusion: The treatment performed besides being aesthetically satisfactory after 1 year resulted in the control of the disease, preventing the appearance of new lesions and guaranteeing a better quality of life to the patient.

Comparison of Fracture Resistance of Teeth Presenting non-carious Cervical Lesions, Restored with Different Composite Materials

“…Non-carious cervical lesions (NCCL), defined as loss of dental tissue in absence of bacterial aggression, have a multifactorial etiology, implying abrasion, abfraction and acid erosion, acting independently or associated [1,2]; other causes are considered controversial, some implying the stress transmitted in cervical area by occlusal loads, especially at patients with a history of bruxism, or behavioral factors such as too intense tooth brushing techniques, diet factors such as a low salivary pH by consuming acidic food (for example, citrus fruits) and drinks and also contributing factors such as periodontal disease [3][4][5]. Prevalence of NCCL is over 85%, gravity and spread increasing among older ages [6].…”

Diagnostics of non-carious lesions of dental hard tissues with the methods of optical spectroscopy and radiography

“…This kind of pathology is the most widely common, next to caries, which often leads to progressive loss of dental enamel and dentin. This hard tissue loss may lead to the decrease of chewing function and even cosmetic defects [1][2][3]. An early non-carious lesion, which can be clinically detected quite often, is the abfraction or wedge-shaped defect.…”
