Preventive potential of nano silver fluoride versus sodium fluoride varnish on enamel caries like lesions in primary teeth: in vitro study

Abstract Background Professionally applied topical fluoride preparations have been used for years, and have been proven to reduce dental decay. This study was designed to determine the effect of experimental nano silver fluoride varnish on the prevention of in vitro demineralization of initially clear enamel in primary teeth. Methods Forty-eight extracted/exfoliated sound molars were sectioned buccolingually into 96 specimens and randomly divided into two separate groups randomly. After all of the specimens were exposed to a demineralization pH cycling system for seven days, the test conditions were applied, then all of the specimens were exposed to a demineralization pH cycling device for 7 days. Specimens were tested for surface microhardness using Vickers microhardness device, and lesion depth was determined by a polarized light microscope using image J 1. 46r software. NSF had a similar effect to FV in restricting vitro enamel demineralization induced by acidic challenge.

Effect of silver diammine fluoride on micro-ecology of plaque from extensive caries of deciduous teeth - in vitro study

Abstract Background: The mechanism of action of silver diammine fluoride on plaque micro-ecology is rarely investigated. After topical SDF therapy, this research investigated micro-ecological changes in dental plaque on large caries of deciduous teeth. Before tooth extraction, unstimulated saliva collection and initial plaque testing were done, and then each caries was topically treated with 38% SDF in vitro. Following pyrosequencing of the DNA from the plaque sample using the Illumina MiSeq device, post-intervention micro-ecological shifts, including microbial diversity, microbial metabolism, and species correlations were investigated and compared, as well as species correlations were investigated and compared. Results: Microbial diversity decreased after SDF application, but not statistically significant. Microbial community composition post-intervention in this regard was noticeably different from that of the supra-intervention and pre-intervention plaque as well as saliva. Conclusions: SDF has a broad antimicrobial effect on dental plaque, which may reduce carbohydrate metabolism in dental plaque and help maintain a healthy balance of the plaque flora.

Effect of silver diammine fluoride on micro-ecology of plaque from extensive caries of primary teeth - in vitro study

Abstract Background The mechanism of action of silver diammine fluoride on plaque micro-ecology is not well understood. This paper looked at microscopic shifts in dental plaque on large caries of deposed teeth following topical SDF therapy. Before tooth extraction, tooth extraction was carried out by unstimulated saliva collection and initial plaque testing, and then each caries was treated with 38 percent SDF in vitro. After pyrosequencing of the DNA from the plaque sample using the Illumina MiSeq platform, post-intervention micro-ecological changes, including microbial diversity, microbial metabolism, and species correlations were investigated and compared. The Microbial community composition post-intervention was noticeably different from that of supra-intervention and pre-intervention plaques, as well as saliva. Conclusions SDF has a major antimicrobial effect on dental plaque, which may reduce carbohydrate metabolism in dental plaque and help promote a new balance of plaque flora.

Prevalence of dental caries in decidous teeth and oral health related quality of life among preschool children aged 4-6 years in Kisarawe, Tanzania.

Poor oral hygiene in preschool children goes beyond dental health, with oral hygiene-related quality of life being tied to overall system health as well as one's quality of life. In a sample of preschool children in Kisarawe, the aim of this investigation was to determine the prevalence of dental caries and its effects on the OHRQoL. [Adjusted OR=0. 21, ]: Children under the buccal surface of upper anterior teeth’s buccal surface were less likely to have decayed teeth. In this sample of preschoolers, the overall effects of dental caries prevalence to OHRQoL were poor. Children in Kisarawe, Tanzania, were shown to be more likely to have a decayed tooth among preschoolers. u2018do your teeth hurt you now?u2019do your teeth hurt you now?u2019do your teeth hurt your teeth?

Prevalence of dental caries in decidous teeth and oral health related quality of life among preschool children aged 4-6 years in Kisarawe, Tanzania.

Poor oral hygiene in preschoolers goes beyond dental health, with oral health and overall wellbeing being tied to overall systemic health as well as one's quality of life. In a sample of preschoolers in Kisarawe, the purpose of this survey was to determine the prevalence of dental caries and its impacts on the OHRQoL. Preschool children with no visible plaque on the buccal surface of upper anterior teeth's buccal surface were less likely to have decayed teeth [Adjusted OR=0. 21, ]. In this sample of preschool children, the overall effects of dental caries prevalence to OHRQoL were low. Kinder in Kisarawe, Tanzania, were more likely to have a decayed tooth than ever before.

SEM Analysis of Residual Dentin Surface in Primary Teeth Using Different Chemomechanical Caries Removal Agents

u2013 Group 1 u2013 2 with Carie Care: Twenty extracted primary molars with active occlusal carious lesions were randomly assigned two groups based on the CMCR agent used for the caries digs: U2013 Group 1 u2013, with Papacarie Duo and Group u2013 2 U2013 2 u2013 with Carie Care, u2013 2: Study results: Twenty extracted primary molars with erective carious lesions, u2013. Results: Despite the fact that both agents demonstrated the minimal smear layer with the patent dentinal tubules, Carie care showed patent dentinal tubules with a prominent peritubular and intertubular collagen network.

Microleakage Evaluation of Composite Restorations Following Papain-Based Chemo-Mechanical Caries Removal in Primary Teeth

Aim: To examine the microleakage of composite restorations following Papain-based chemo-mechanical caries removal as compared to the traditional drilling process. Using scanning electron microscopy, the hybrid layer's characteristic was also investigated. Three newly extracted and exfoliated primary molars with open proximal carious dentin lesions were found in the study. The resin/dentin interface was investigated by scanning electron microscopy after a microleakage test. Longer and numerous resin tags were found with a statistically thicker hybrid layer in the Papacarie group, with statistically superior thicker layer than those following the drilling process. However, there was no significant difference between the diameters of resin tags of both groups.

Dentin Topographic Features following Chemomechanical Caries Removal in Primary Teeth

Aim: The topographic characteristics of dentin after caries removal with a chemomechanical agent were discovered by a researcher compared to the conventional drilling technique. Using the scanning electron microscope, following caries removal, dentin topography, and the cut section were examined. Patent dentinal tubules with open orifices were seen on dentin cut surfaces. Patent dentinal tubules were discovered with their orifice layer plugged with smear layer on the cut dentin surfaces. Conclusions: Papacarie manufactured a rough and porous surface with partial or complete removal of the smear layer and opened dentinal tubules, opening dentinal tubules, while the drill produced a smooth surface with a uniform smear layer occluding the dentinal tubules.

Diagnostic Performance of Different Methods in Detecting Incipient Non-Cavitated Occlusal Caries Lesions in Permanent Teeth

Aim: The objective of this in vitro research was to determine the results of the new caries detection devices on the incipient occlusal caries. According to the ICDAS II score, 100 permanent molar teeth, which were believed to have incipient enamel caries, were found in our research. Caries measurements have been applied to all teeth by using the DIAGNOdent pen, CarieScan PRO, and SoproLife camera after the visual inspection. Although SC had the highest sensitivity and specificity value at D1 and D2 thresholds, CP reported the lowest values, with the lowest values being shown. The most significant area under ROC curves was found in ICDAS II. Conclusions: The ICDAS II, a medical imaging system that is used in conjunction with other diagnostic procedures, is considered to be sufficient in order to diagnose premature occlusal caries. Since the benefits of displaying caries lesion on the computer monitor, follow-up, and encouragement of the patients, SC can be used as an alternative to the ICDAS II.

Caries Progression Rate in Primary Teeth: A Retrospective Study

Objectives: The rate of caries progression in primary teeth has never been investigated, with most studies on early childhood caries focusing on the percentage of lesions that are stable at a certain level of disease over a period of time. The aim of the current research was to investigate the incidence and behavior of proximal and occlusal carious lesions in primary teeth among children from low socioeconomic status. The presence of proximal surfaces and occlusal caries improvement was assessed, and statistical analyses were performed to determine caries progression rates.
