Effect of cheese and casein phosphopeptide-amorphous calcium phosphate on erosive lesions of primary teeth enamel following exposure to amoxicillin and ibuprofen syrups: An in vitro study.

Background: The acidic component of liquid medicinal syrups used by pediatric patients may cause erosion and partial demineralization. This study aimed to evaluate the effect of cheese and casein phosphopeptide-amorphous calcium phosphate (CPP-ACP) on erosive lesions of primary teeth enamel following exposure to amoxicillin and ibuprofen syrups. Materials and Methods: In this in vitro study, 60 noncarious deciduous molars were used. After measuring the surface microhardness of the samples, they were randomly separated into two groups and immersed in either amoxicillin or ibuprofen for 1 min three times per day. CPP-ACP, cheese, and artificial saliva were then applied to each of the three subgroups (n = 10). After each immersion time, 10 min of therapy was given. Between treatment intervals, the samples were kept in artificial saliva. The microhardness was remeasured after 1 week. Data were analyzed using SPSS software through repeated-measures ANOVA (α = 0.05). Results: All samples' microhardness reduced considerably after immersion in liquid pharmaceuticals (amoxicillin [84.9 kgf/mm2] and ibuprofen [75.1 kgf/mm2]), but increased significantly following exposure to therapeutic solutions. There was no difference between the amoxicillin-cheese and amoxicillin-CPP-ACP subgroups (P = 0.975). A statistically insignificant difference was found between the ibuprofen group and the ibuprofen-CPP-ACP subgroup (P = 0.499). Conclusion: As a result, cheese and CPP-ACP can be utilized to remineralize erosive lesions caused by amoxicillin or ibuprofen exposure.

Evaluation of the Effect of NovaMin and Er,Cr:YSGG Laser on Remineralization of Erosive Lesions of Primary Enamel Teeth: An In Vitro Study.

Introduction: The purpose of this in vitro study is to ascertain how NovaMin and Er,Cr:YSGG laser radiation affect the remineralization of primary tooth enamel lesions. Methods: 40 main teeth served as the study's sample size. These teeth were allocated into five groups at random. The first group served as a negative control (artificial saliva); the second group served as a positive control (APF gel 1.23%); the third group NovaMin, the fourth group Er,Cr:YSGG laser, the fifth group Er,Cr:YSGG laser and finally, the application of NovaMin. For the purpose of measuring microhardness, all samples were submitted to the dental materials laboratory three times. Results: The collected data were compared using the SPSS 28 program between the baseline measurement, after demineralization, and after remineralization. The data were analyzed using ANCOVA and Bonferroni tests. All groups demonstrated a considerable increase in microhardness as compared to the negative control group (P<0.05). With the exception of the third and fourth groups, there was no discernible difference in the rise in microhardness between the other groups. The third and fourth groups were compared, and the results revealed that NovaMin had a greater impact than laser therapy alone (P=0.023). Scanning electron microscopy (SEM) analysis backed up the findings. Conclusion: In comparison to using the Er,Cr:YSGG laser alone, using NovaMin alone can speed up the remineralization of erosion lesions on the surface of primary teeth.

Dietary branched-chain amino acids intake, glycemic markers, metabolic profile, and anthropometric features in a community-based sample of overweight and obese adults.

BACKGROUND: Existing research provides conflicting evidence regarding the relationship between estimated branched-chain amino acid (BCAA) intake and metabolic, glycemic markers, and anthropometric characteristics. This research seeks to examine the association between estimated dietary BCAA consumption and glycemic, and metabolic markers, as well as anthropometric parameters in adults classified as overweight or obese. METHODS: In this cross-sectional analysis, we gathered data from 465 overweight and obese individuals aged between 18 and 37 years. To evaluate dietary data, we employed the food frequency questionnaire, and the BCAA content in foods was determined via the United States Department of Agriculture website. We utilized ELISA kits to measure fasting blood glucose (FBS) and lipid profile markers, and additionally calculated low-density lipoprotein (LDL) and insulin sensitivity markers. We assessed sociodemographic status, physical activity (PA), and anthropometric attributes through a method recognized as both valid and reliable. For statistical analysis, we conducted analyses of covariance (ANCOVA), making adjustments for variables including sex, PA, age, energy, and body mass index (BMI). RESULTS: Upon adjusting for confounders, those in the highest tertiles of BCAA intake exhibited an increase in weight, BMI, waist circumference (WC), waist-to-hip ratio (WHR), and fat-free mass (FFM). Conversely, they demonstrated reduced fat mass (FM) (%) and FM (kg) compared to their counterparts in the lowest tertiles (P < 0.05). Additionally, there was a noted association between greater estimated BCAA intake and reduced LDL levels. Nonetheless, our findings did not reveal a significant relationship between dietary BCAA and glycemic indices. CONCLUSIONS: From our findings, an increased estimated intake of BCAA seems to correlate with diminished serum LDL concentrations. To gain a more comprehensive understanding of this association, it is imperative that further experimental and longitudinal studies be conducted.

Beyond the mouth: the impact of periodontal disease on dementia.

DATA SOURCES: The authors searched Medline via PubMed, Scopus, CINAHL, Web of Science, and PsycINFO for relevant studies published until April 2022. STUDY SELECTION: Longitudinal studies that assessed periodontal health as the exposure and cognitive decline and/or dementia as the outcome were included. Case reports, reviews, cross-sectional studies, and animal studies were excluded. DATA EXTRACTION AND SYNTHESIS: Two authors independently reviewed studies for inclusion, extracted data, and assessed study quality. Meta-analysis was conducted to generate pooled odds ratios (ORs) for cognitive decline and hazard ratios (HRs) for dementia. Sources of heterogeneity were explored through subgroup analyses. RESULTS: A total of 24 studies were included for cognitive decline and 23 for dementia. Poor periodontal health was associated with increased odds of cognitive decline (OR = 1.23; 95% CI: 1.05-1.44) and dementia (HR = 1.21; 95% CI: 1.07-1.38). Tooth loss also appeared to increase the risk independently. However, significant heterogeneity existed between studies. CONCLUSIONS: Poor periodontal health may increase the risk of cognitive decline and dementia, but the quality of evidence was low. Further high-quality, longitudinal studies with standardized assessments are needed to establish causality.
