Remineralization Effect of Egg Shell Powder and Novamine on Initial Caries-Like Lesions in Young Permanent Teeth (In-Vitro Study)

Abstract

INTRODUCTION: Despite the cariostatic effect of fluoride, the continuous use of fluoridated toothpastes increases the risk of dental fluorosis. Therefore, new safe alternative technologies of teeth remineralization must be introduced to arrest dental caries and remineralize the early enamel carious lesions. OBJECTIVES: The aim of the study was to evaluate the remineralizing effect of eggshell powder and novamine on initial caries-like lesions in young permanent teeth compared to fluoride. MATERIALS AND METHODS: A total of 96 permanent teeth were selected. Each Tooth was coated with nail varnish, leaving squares of 4x4 mm. Each tooth was sectioned into 2 halves longitudinally in a buccolingual direction through the center of the window to obtain a mesial and a distal half (192 specimens). One half was treated and the other half was remained untreated to serve as its negative control. Teeth were assigned into three groups according to treatment agent; group I (eggshell powder solution), group II (novamine toothpaste) and group III (fluoride toothpaste) .Specimens were immersed in the demineralizing solution for 72 hours to produce artificial carious lesions on the exposed enamel surface. RESULTS: There was a statistically significant mean microhardness and lesion depth values between test subgroups IA (eggshell powder), IIA (novamine) and their controls (P<0.001). There was no statistically significant difference in mean microhardness and lesion depth values between the test subgroup IIIA (fluoride) and its control (P>0.001). There was statistically significant difference in mean percent difference values of enamel microhardness among three groups (P<0.001). There was no statistically significant difference in mean percent difference values of lesion depth between the three groups (P>0.001). CONCLUSION: Both eggshell powder and novamine were effective for remineralization of initial caries-like lesions of young permanent teeth.

Remineralization Effect of Eggshell Powder on Post-Orthodontic White Spot Lesions Compared to CPP-Acp: A Randomized Controlled Clinical Trial

“…Six months follow up displayed the statistically significantly lowest readings. These results agree with Mony et al (2015) (28) , Haghgoo et al in 2016 (26) , Elbahrawy and El-Dosoky (2019) (29) , and Mohamed et al (2020) (31) that ESP is effective and is promising in remineralization of enamel caries lesions.…”

Evaluation of the Antibacterial Activity and the Remineralizing Potentiality of Two Natural Extracts and Their Mixture (In Vitro Study)

“…The current study proved that all of the prepared extracts had strong antibacterial effect against S. mutants as shown in table (1) and Figure 3. The antibacterial activity of ginger against S. mutants might be due to its valuable phytoconstituents which had a good binding affinity to the surface protein antigen of S. mutant, in addition to the hydrophobic interactions with the protein active site that increase the inhibitory effect against S. mutans surface protein antigen [2], [14].…”

“…Dental caries is considered a chronic disease throughout the whole world and still has a high prevalence in spite of having different developments in the field of dentistry focusing primarily on shifting to preventive dentistry [1]. It has been assumed that the main cause of caries is the cariogenic bacteria that cause demineralization and white spot lesions resulting in dissolution of the apatite crystals in addition to loss of the calcium and phosphate ions from the tooth surface [2].…”

Effect of Egg Shell and White Tea Dentin Pretreatment on Microtensile Bond Strength of Universal Adhesive System

“…The minerals of ESP when come in contact with carious lesions; they pass through the superficial layer obstructing the surface porosities. ESP solution can be used as a remineralizing agent in preventive dentistry as an alternative to fluoride (17) .…”
