Mechanical Properties of Poly(Alkenoate) Cement Modified with Propolis as an Antiseptic.

Background: We assessed the effect of propolis on the antibacterial, mechanical, and adhesive properties of a commercial poly(alkenoate) cement.

Methods: The cement was modified with various concentrations of propolis, and antibacterial assays were performed against . by both MTT assays and agar diffusion tests.

Effects of Neutralization on the Physicochemical, Mechanical, and Biological Properties of Ammonium-Hydroxide-Crosslinked Chitosan Scaffolds.

It has been reported that chitosan scaffolds, due to their physicochemical properties, stimulate cell proliferation in different tissues of the human body. This study aimed to determine the physicochemical, mechanical, and biological properties of chitosan scaffolds crosslinked with ammonium hydroxide, with different pH values, to better understand cell behavior depending on the pH of the biomaterial. Scaffolds were either neutralized with sodium hydroxide solution, washed with distilled water until reaching a neutral pH, or kept at alkaline pH.

Dental anomalies in cleft lip and palate: A case-control comparison of total and outside the cleft prevalence.

This study's objective was to compare the total and outside the cleft prevalence of dental anomalies (DA) between patients with cleft lip and palate (CLP) and a control group. This retrospective cross-sectional study was done under a case-control design. The case group consisted of 192 non-syndromic patients with complete CLP, while the control group included 411 patients.

Growth differences in patients with dental agenesis, how its location impacts facial morphology.

Background/purpose: Non-formation of a tooth impacts the morphology of the alveolar bone, which may, in turn, generate an imbalance in facial growth. This retrospective case-control study aimed to determine whether observable differences exist in the facial growth of patients with dental agenesis relative to complete dentition controls.

Materials And Methods: The sample comprised 75 patients with dental agenesis, and each case was paired with two controls of the same age and gender ( = 150).

Prevalence of Obesity in Elementary School Children and its Association with Dental Caries.

Purpose: To determine any associations between obesity and caries activity in the mixed dentition stage among primary school children in a low-income Mexican primary school.

Materials And Methods: This cross-sectional study was performed in Mexican schoolchildren aged 8-12 years. The body mass index (BMI) was obtained, and children were classified as overweight/obese considering age and sex.

In vitro histomorphometric comparison of dental pulp tissue in different teeth.

Background: Dental pulp (DP) represents an accessible and valuable source promising of stem cells for clinical application. However, there are some disadvantages associated with the isolation of dental pulp stem cells (DPSCs), which include the size and weight of the pulp tissue needed to yield sufficient cells for culturing in vitro. Therefore, the objective of this study was to compare in vitro histomorphometry of DP from permanent (premolars, third molar), supernumerary and deciduous teeth of patients between 5 and 25 years old with regards to weight, length, width and the cell density in the four regions of the DP in order to obtain quantitative parameters in a tissue that represents a valuable source of stem cells.

Impacted Maxillary Canine Prevalence and Its Association with Other Dental Anomalies in a Mexican Population.

. We quantified the prevalence of impacted maxillary canines (IMC) and their association with other dental anomalies (DAs). .
