Post-instrumentation dentinal microcracks induced by two NiTi rotary systems with increased super elasticity and shape memory: a microCT comparative and methodological ex vivo study
(MDPI, 2023)
This study aimed to determine the incidence of dentinal microcracks after instrumenting the root canals of maxillary premolars using two novel rotary instrumentation systems. Micro-computed tomography ...
A computer vision-based application for the assessment of head posture: a validation and reliability study
(MDPI, 2023)
As its name implies, the forward head position (FHP) is when the head is further forward of the trunk than normal. This can cause neck and shoulder tension, as well as headaches. The craniovertebral ...
Effects and safety of hypertonic saline combined with airway clearance in non-hospitalized children with recurrent wheezing
(World Scientific Publishing, 2023)
Background: The International Study of Wheezing in Infants defines recurrent wheezing as the presence of three or more medically documented episodes of wheezing within one year. To date, there is no ...
Enamel evaluation after debonding of fixed retention and polishing treatment with three different methods
(MDPI, 2023)
Lack of standardization of the retention phase has led to many studies of stability of movements and characteristic of retainers, disregarding the enamel repercussions of fixed retention on this phase. ...
STEM education in childhood: perceptions of teachers

Relevant aspects of titanium topography for osteoblastic adhesion and inhibition of bacterial colonization
(MDPI, 2023)
The influence of the surface topography of dental implants has been studied to optimize titanium surfaces in order to improve osseointegration. Different techniques can be used to obtain rough titanium, ...
Implant surface physicochemistry affects keratinocyte hemidesmosome formation
(John Wiley & Sons, 2023)
Previous studies have shown hydrophilic/hydrophobic implant surfaces stimulate/hinder osseointegration. An analogous concept was applied here using common biological functional groups on a model surface ...
