Clinical Wear Assessment of Composite Restorations Using a Digital Optical Surface Profilometry - A Retrospective Study
Article | IMSEAR | ID: sea-215228
ABSTRACT
Dental composites form the main stay in majority of the restorative procedures due to their aesthetic properties and adhesive technology. The major disadvantage with these materials is that they have less abrasion resistance and they wear on clinical service. The aim of this study was to evaluate the wear resistance of mandibular molar class-1 composite restored teeth at different intervals of time. METHODSIn this retrospective pilot study, thirty patients were randomly selected with mandibular first and second molars restored with class-1 composite restorations and were grouped according to the retrospective clinical duration of the teeth restored as 1-3 years, 3-5 years and 5-7 years. High resolution images of these restorations were captured using DSLR with macro lens attached and assessed for surface irregularities and the clinical duration of the restoration was recorded. The images were magnified using NIH-IMAGE J and processed in Adobe Photoshop and digital optical surface profilometry was used to measure the irregularities formed on the surface of the restoration. RESULTSThere was a significant increase in the mean, maximum and minimum diameter of craters and notches formed between the three groups (p < 0.05). But there was no statistically significant difference that was seen with the area of tooth assessed, length and angle of craters formed (p > 0.05). CONCLUSIONSWear of the restorations increased on increased clinical duration and varied according to the dietary habits of the patients.
