Enamel is composed of approximately 98% inorganic material in the form of hydroxyapatite crystals, making it the hardest tissue in the human body [1, 2]. This chemical composition is a critical factor for dentists in determining treatment plans. The integrity of enamel is a key indicator for ...
The COVID-19 pandemic has had an unprecedented and disruptive impact on people’s health and lives worldwide. In addition to burdening people’s health in the short-term in the form of infection, illness, and mortality, there has been an enormous negativ
When teeth tip forward (procline), their incisal edges form an arc of greater circumference than the root apices, leading to increased inter-canine width [21]. Grunheid et al. studied the efficacy of clear aligners in increasing the transverse dimension and found a greater tendency for ...

and found that it only take 6 s to form the coarsen basket weave structure at the temperature of 806 °C. To complete the phase transformation by heat treatment, it has to take 15 min at high temperature of 980 ± 5 °C. Ma and his coworkers [30] have observed nanocrystalline γ...
In addition to MACC formation through a metabolic route, ACC can also be conjugated in the form of 1-glutamyl-ACC (GACC) in a reaction that is catalyzed by γ-glutamyl transpeptidase (GGT; EC 2.3.2.2) [25]. Another possible ACC metabolic pathway is the reaction catalyzed by the enzyme ...
Briefly, 225 mg of purified soy lecithin and 25 mg of cholesterol were dissolved in dichloromethane (6 ml) to form an organic solvent mixture. Then, 45 mg of ACCF was added to the mixture, and the resulting solution was dried into a thin lipid film using a rotary evaporator (YR02306, ...

[118]. The study suggested that reduced susceptibility was not due to decreased membrane permeability, but may have been due in part to the ability to form biofilm. In a recent study, whole genome sequencing revealed thatS. marcescensrecovered from an in-use hospital disinfectant containedsdeXY,...
The third aspect is the vertical eruption of the posterior mandibular teeth to form stable Class I occlusal contact relations. Therefore, studying the biomechanical behavior of masticatory muscles and TMJ is of significant importance for understanding the treatment and recurrence of patients with Skeletal...
