Aim: This study aimed to explore the possible bidirectional interrelations between fructose-induced metabolic syndrome (MS) and apical periodontitis (AP).
Methodology: Twenty-eight male Wistar rats were distributed into four groups (n = 7, per group): Control (C), AP, Fructose Consumption (FRUT) and Fructose Consumption and AP (FRUT+AP). The rats in groups C and AP received filtered water, while those in groups FRUT and FRUT+AP received a 20% fructose solution mixed with water to induce MS.

Healthy eating habits may protect adolescents against disease development, ensure optimal physical and cognitive development, and may persist in adulthood. However, adolescents usually prefer sweetened dairy products and show a low consumption of vegetables, fruits, whole grains, and pulses. Co-creation offers an innovative and inclusive alternative for the development of new products.

To analyze whether the single-nucleotide polymorphisms (SNPs) in Matrix metalloproteinases 2, 3, and 9 (MMP2, MMP3, and MMP9), Tissue Inhibitor of Metalloproteinases 1 and 2 (TIMP1 and TIMP2), methionine synthase (MTR) and methionine synthase reductase (MTRR) influence delayed deciduous tooth eruption (DDTE). This cross-sectional study included 1060 biologic unrelated children (aged between 6 and 36 months) of both sexes, selected from 25 public schools in Nova Friburgo, Rio de Janeiro, Brazil. Oral examination was conducted and DDTE was defined by the absence of gingival eruption according to a chronology based on the Brazilian population.

Purpose: This systematic review, meta-analysis, and meta-regression aims to determine whether surgical treatment for proximal humeral fractures is superior to non-surgical treatment regarding pain, functionality, complications, and new surgery rates.
Methods: We systematically reviewed clinical trials from PubMed (MEDLINE), EMBASE, Web of Science, Scopus, and Cochrane up to April 2024. Data comparing surgical or conservative of proximal humeral fractures were retrieved for outcomes of pain, functionality, adverse events, and new surgeries.

Dental implants are essential for the prosthetic rehabilitation of edentulous patients, requiring adequate bone volume and density for osseointegration and load support. The posterior region of the maxilla, commonly deficient in bone quality and quantity, represents a clinical challenge. This case series reports an analysis involving 69 dental implants in the atrophic maxilla of nine patients.

Obesity is characterized by an imbalance between energy intake and expenditure that triggers abnormal growth of adipose tissues. Dimethyl fumarate (DMF) and its primary active metabolite, monomethyl fumarate (MMF), are Nrf2 activators and have been recognized as strategic antioxidants. This study aimed to evaluate the potential of MMF and DMF to interfere with adipogenesis and obesity, and identify the molecular mechanisms involved.

This study assessed the impact of pre-enlarging the root canal using a size 25 K-file on the fracture incidence of three reciprocating instruments after multiple uses. After a glide path performed with a size 15 K-file, the instruments (Reciproc R25, Reciproc Blue R25, and WaveOne Gold Primary) were initially used in 936 root canals. Then, for the second and third uses (933 and 927, respectively), a pre-enlargement using a size 25 K-file at the working length was done.

Neuron-glia interactions are fundamental to the development and function of the nervous system. During development, glia, including astrocytes, microglia, and oligodendrocytes, influence neuronal differentiation and migration, synapse formation and refinement, and myelination. In the mature brain, glia are crucial for maintaining neural homeostasis, modulating synaptic activity, and supporting metabolic functions.
