The correlation between dental caries and dermatoglyphics: a systematic review and meta-analysis.

Here, we used a meta-analysis approach to systematically evaluate the correlation between dental caries and dermatoglyphics. To identify findings relating to the association between dental caries and dermatoglyphics, a methodical literature search was conducted in the PubMed, Embase, Cochrane Library, and Web of Science databases from inception to August 2023. Data analysis was performed using RevMan 5.

Adverse effects of articaine versus lidocaine in pediatric dentistry: a meta-analysis.

Over the last few years, numerous reports have lauded the efficacy of articaine hydrochloride as a local anesthetic (LA) in dental procedures. Numerous studies have shown that articaine outperforms lidocaine in various aspects of dental treatment, leading to its widespread adoption in both adults and children. Despite the publications of comparative studies, there remains a dearth of systematic reviews examining the adverse effects of articaine versus lidocaine in randomized controlled trials.

Randomized Crossover Study of Auricular Plaster Therapy to Relieve Dental Anxiety in Children.

Objective: To determine if auricular plaster therapy (APT) can alleviate dental anxiety in children aged 9 or 10 years old.

Methods: A crossover research was conducted on children with at least two deep-arrested deciduous molar caries ( = 80?). The first group ( = 40) received APT intended to reduce anxiety prior to the first caries treatment, whereas the second group ( = 40) received placebo/control APT (no anticipated impact on anxiety).

Rational Design of Ag-Based Catalysts for the Electrochemical CO Reduction to CO: A Review.

The selective electrochemical CO reduction (ECR) to CO in aqueous electrolytes has gained significant interest in recent years due to its capability to mitigate the environmental issues associated with CO emission and to convert renewable energy such as wind and solar power into chemical energy as well as its potential to realize the commercial use of CO . In view of the thermodynamic stability and kinetic inertness of CO molecules, the exploitation of active, selective, and stable catalysts for the ECR to CO is crucial to promote the reaction efficiency. Indeed, plenty of electrocatalysts for the selective ECR to CO have been explored, of which Ag is known as the most promising electrocatalyst for large-scale ECR to CO due to several competitive advantages including high catalytic performance, low price, and rich reserves compared with other metal counterparts.

MicroRNA-1225 activates Keap1-Nrf2-HO-1 signalling to inhibit TNFα-induced osteoclastogenesis by mediating ROS generation.

The influence of miRNA-1225-5p (miR-1225) and Keap1-Nrf2 signalling on in vitro osteoclast differentiation in mouse models was studied along with the underlying mechanism. In differentiated bone marrow-derived macrophages (BMMs), downregulated miR-1225 and upregulated Keap1 were observed in the course of receptor activator of nuclear factor kappa-Β ligand (RANKL)-mediated osteoclastogenesis. Bioinformatic analysis and dual-luciferase reporter assay showed that miR-1225 targeted the three prime untranslated region (3'-UTR) of Keap1 mRNA and caused its degradation.

Roles of SP600125 in expression of JNK, RANKL and OPG in cultured dental follicle cells.

Objective: To investigate the expression of C-JNK, RANKL and OPG after SP600125 administration in cultured dental follicle cells (DFCs).

Methods: TRAP staining and electron microscope were carried out on day 7 and 9 after coculture of BMMs and DFCs with a ratio of 5:1 in different groups. To determine the effects of SP600125 on the expression of C-JNK, RANKL and OPG mRNA and protein, cultured DFCs were divided into control group, DMSO group and SP600125 groups.

Auricular Acupressure Improves Habit Reversal Treatment for Nail Biting.

Objective: Nail biting leads to a variety of health issues. Habit reversal treatment is a major approach to cease nail biting, but is often ineffective since patients continue to suffer from anxiety, a major trigger. This study investigated whether the potential anxiety relief provided by auricular acupressure could improve the efficacy of habit reversal treatment, as evidenced by improved stomatological and other outcomes.

The highly selective oxidation of cyclohexane to cyclohexanone and cyclohexanol over VAlPO berlinite by oxygen under atmospheric pressure.

Background: The oxidation of cyclohexane under mild conditions occupies an important position in the chemical industry. A few soluble transition metals were widely used as homogeneous catalysts in the industrial oxidation of cyclohexane. Because heterogeneous catalysts are more manageable than homogeneous catalysts as regards separation and recycling, in our study, we hydrothermally synthesized and used pure berlinite (AlPO) and vanadium-incorporated berlinite (VAlPO) as heterogeneous catalysts in the selective oxidation of cyclohexane with molecular oxygen under atmospheric pressure.

Phosgene-free synthesis of hexamethylene-1,6-diisocyanate by the catalytic decomposition of dimethylhexane-1,6-dicarbamate over zinc-incorporated berlinite (ZnAlPO4).

The phosgene-free synthesis of hexamethylene-1,6-diisocyanate (HDI) by the decomposition of dimethylhexane-1,6-dicarbamate (HDU) was carried out on a self-designed fixed-bed catalytic reactor, using zinc-incorporated berlinite (ZnAlPO4) as catalyst, dioctyl phthalate (DOP) as solvent and N2 as carrier gas. Factors influencing the yield of HDI, including the Zn/Al molar ratio, HDU concentration and liquid space velocity (LHSV), were investigated. Under the optimized reaction conditions, i.

[Odontogenic differentiation of bone marrow-derived mesenchymal stem cells induced by periodontal ligament stem cells].

Objective: To investigate the mechanism underlying the mechanism of odontogenic differentiation of bone marrow-derived mesenchymal stem cells (BMMSCs) induced by periodontal ligament stem cells (PDLSCs), and offer an experimental evidence for the combination of the two types of stem cells to make regenerative periodontal complex.

Methods: By means of Transwell(R); chamber, PDLSCs and BMMSCs from miniature pigs were co-cultured indirectly at different mixing ratios of PDLSCs to BMMSCs, 10:1 (group A), 1:1 (group B), 1:10 (group C). On the other hand, PDLSCs and BMMSCs were respectively cultured alone as positive and negative control group.

[Expression of tumor necrosis factor in placenta tissue of pregnant rats with chronic peridontitis].

Objective: To examine the expression of tumor necrosis factor in placenta of pregnant rats with chronic periodontitis.

Methods: Twenty Wistar female rats were randomly divided into two groups, control (n = 8) and experimental group (n = 12). The periodontitis model was established in the experimental group.

Catalysis over zinc-incorporated berlinite (ZnAlPO4) of the methoxycarbonylation of 1,6-hexanediamine with dimethyl carbonate to form dimethylhexane-1,6-dicarbamate.

Background: The alkoxycarbonylation of diamines with dialkyl carbonates presents promising route for the synthesis of dicarbamates, one that is potentially 'greener' owing to the lack of a reliance on phosgene. While a few homogeneous catalysts have been reported, no heterogeneous catalyst could be found in the literature for use in the synthesis of dicarbamates from diamines and dialkyl carbonates. Because heterogeneous catalysts are more manageable than homogeneous catalysts as regards separation and recycling, in our study, we hydrothermally synthesized and used pure berlinite (AlPO4) and zinc-incorporated berlinite (ZnAlPO4) as heterogeneous catalysts in the production of dimethylhexane-1,6-dicarbamate from 1,6-hexanediamine (HDA) and dimethyl carbonate (DMC).
