Abstract

Aim

This study is aimed to evaluate the effect of staining solutions on the color stability of bulk fill and conventional nanohybrid resin composites (RCs) when subjected to various immersion periods.

Materials and methods

A total of 120 cylindrical Teflon molds (4 × 4 mm) were obtained and divided into four groups of 30 each. Molds of groups I and II were filled with Tetric N Ceram Bulk Fill (Ivoclar Vivadent, Schaan, Liechtenstein) and Filtek Bulk Fill (3M ESPE, St. Paul, MN, USA). Molds of groups III and IV were filled with Tetric N Ceram (Ivoclar Vivadent) and Filtek Z250 XTE (3M ESPE) incremental fill RC. Photo-activation was performed and specimens were incubated. Spectrophotometer analysis was done according to Commission Internationale d'Eclairage Lab color scale. After taking the baseline measurements, 10 samples from each group were immersed in distilled water (control, subgroup a), tea (subgroup b), and coffee (subgroup c) respectively, for 1, 7, and 30 days. The color values of each specimen were remeasured and color change value (E*ab) was calculated after 1, 7, and 30 days. Data were analyzed by Friedman's test and Mann–Whitney U-test; p < 0.05 is considered to be statistically significant.

Results

Group III specimens showed perceptible color changes at 30-day immersion period in coffee and tea. In group I specimens, color changes were perceptible at 7- and 30-day immersion periods in coffee and only 30-day immersion period in tea. Groups II and IV specimens showed perceptible color changes after all immersion periods in coffee and after 30 days in tea.

Conclusion

It can be concluded that Tetric N Ceram has less color change than the other nanohybrid RCs investigated when immersed in coffee and tea after various immersion periods.

Abstract

Introduction

White spot lesion is the early sign of demineralization occurring under intact enamel which may lead to the development of caries.

Aim

The aim of this study is to compare and evaluate the caries-preventive efficacy of a resin infiltrant, casein phosphopeptideamorphous calcium phosphate (CPP-ACP), and nanohydroxyapatite (nano-HA) on white spot enamel lesions.

Settings and designs

A total of 40 freshly extracted human maxillary incisors were used in this study. Enamel samples (2 mm thickness) were prepared and sample preparation windows were created (dimension of 5 × 5 mm) using adhesive tape, and the sample was made completely resistant to acid attack by coating nail varnish.

Materials and methods

The samples were divided into four groups, which are resin infiltrant, CPP-ACP, nano-HA, and control of 10 enamel samples in each group. The samples were evaluated using confocal laser scanning microscopy before and after the application of resin infiltrant and remineralizing agents.

Statistical analysis

Statistical analysis was done using analysis of variance and post hoc Bonferroni test was used for comparing intragroups and Tukey test for comparing intergroups.

Results

The mean value after demineralization is 245, 246, 250, and 247 μm for Groups I to IV. After remineralization, group I > group II > group III > group IV. After acid challenge for a period of 14 days, group I > group II > group III > group IV.

Conclusion

The resin infiltrant showed higher caries inhibition potential and superior acid resistance than CPP-ACP and nano-HA.

Clinical significance

The inhibition of caries progression by resin infiltration technique should be considered as an alternative approach to the more invasive therapies and warrants a place in the range of minimally invasive dentistry techniques.

Abstract

Aim

The aim of the present study is to evaluate the influence of socioeconomic status and social habits on the prevalence of dental caries in Chennai population. Cross sectional study was conducted in 500 patients by survey method using a questionnaire. Data was collected based on demographic details, information on the income, educational qualification, occupation, social habits (tobacco and alcohol consumption) and the caries exposure in terms of presence or absence of dental caries or a restoration. The data was tabulated using Microsoft Excel and statistically analysed using SPSS version 22. 91.8% of subjects in the lower socio economic status have a caries exposure while only 82% and 73.4% of the medium and higher economic status had caries. Within the limitations of the present study it can be concluded that there exists a connection between the individuals' socio economic condition and the oral health status that calls for implementation of oral health programs.

Abstract

Key Messages

The incidence of second distobuccal canal ranges from 1.64 to 9.5%. However, the incidence of third distal canal (distopalatal) is rare (<1%). This report highlights the importance of computed tomography in the successful diagnosis and management of maxillary first molar.
