“…Dental caries is a highly prevalent chronic multifactorial transmissible infection that results in the dissolution of tooth structure by acid metabolites from the bacterial fermentation of carbohydrates in the biofilm with its progress or reversal being determined by the balance between the pathological and the protective factors. In contrast, dental erosion is considered to be a surface phenomenon caused by exposure to the acid of nonbacterial origins[ 3 ] which advances by progressive loss of softened surface layers under further erosive-abrasive challenges.…”

Background: With the increasing prevalence of erosive tooth wear affecting both adults and children; designing optimum protocols of management in a noninvasive manner is gaining precedence. Aim: Comparative evaluation of topically applied calcium phosphate-based agents casein phosphopeptide-amorphous calcium phosphate (CPP-ACP) and beta tricalcium phosphate (β-TCP) on the surface of eroded dentin. Materials and Methods: Dentin blocks from human third molars in four groups were subjected to the surface treatment: (G1) sound dentin (G2) demineralized dentin (G3) CPP-ACP (G4) β-TCP. All the samples except control (G1) were immersed in an acidic solution incubated at 37°C for 96 h. The samples in G3 and G4 were topically treated with CPP-ACP and β-TCP for 4 min twice daily for 14 days; followed by pH-cycling for 21 days. Surface hardness testing and surface morphology were observed using the scanning electron microscopy. Data were analyzed using the Statistical Package for the Social Sciences (SPSS) software with Kruskal-Wallis test and post hoc test. Results: Dentin treated with both CPP-ACP (37.25) and β-TCP (32.05) recorded significantly higher VHN than demineralized (G2-23.51) but lower compared to sound control (G1-57.06). Conclusion: The topical application of CPP-ACP and β-TCP agents shows definite potential in promoting the hardening of demineralized dentin surface.

Dental or tooth wear is a physiological process in the life cycle of teeth. Loss of the occlusal surface may cause excessive tooth wear. Several factors may contribute to tooth wear with different intensities and duration in the oral cavity. The oral cavity is generally compared to a tribological system to determine the various types of wear between teeth and restorative materials and assess the amount of dental wear. However, it is challenging to investigate in vitro and in vivo wear owing to the complexity of tooth wear; thus, a clear correlation between in vitro and in vivo data could not be established. This review is aimed at providing an insight into the etiology of tooth wear and tribological investigations in dentistry.

“…Therefore, a practical technique, or a combination of techniques, is required to achieve a non-destructive assessment of both areas. 6 Until now, non-destructive methods that can perform a clinical, qualitative, and quantitative assessment of mineral loss for enamel demineralization do not exist. This study aimed to evaluate and correlate the mineral content and enamel color change through a statistical correlation model.…”

Objectives: This study was conducted to evaluate the correlation between alteration of enamel mineral content and tooth shade. Materials and Methods:A total of 33 sound bovine enamel blocks (5 x 5 mm, 2 mm thickness), were obtained from the middle third of the labial enamel surface. The samples were divided into three subgroups (n=11/group), where Group I received no surface treatment; Group II represents the demineralized enamel surface, Group III represents the remineralized enamel surface. Scanning Electron microscopic (SEM) examination and Elemental Analysis (EDXA) testing, as well as Color measurement using a color spectrophotometer and micro-hardness evaluation were performed for all samples. Results:The L values revealed a significantly strong negative correlation with carbon (r = -0.74, p = 0.002), but being positively correlated for oxygen (r = 0.59*, p = 0.02215), phosphate (r =0.62*, p = 0.01315) and calcium (r = 0.76, p = 0.00115). In contrast, both a and b values were only positively correlated for carbon (r = 0.67**, p = 0.006; r = 0.72**, p = 0.003 respectively), and negatively correlated for the rest of elements. Vickers microhardness values on the other hand were only negatively correlated with carbon (r = -0.88**, p = 0.000), but positively correlated for the rest elements. Conclusions:The change in the surface elemental content of the bovine enamel affected the lightness and the blue-yellow axis of tooth color, correlating respectively with the L* and b* values.
