Lithium‐Doped Hydroxyapatite Nanowires Rejuvenate Senescent Macrophages Via the Lysosome‐Dependent Ferroptosis Axis to Promote Aged Bone Regeneration

open access: yesAdvanced Science, EarlyView.
Li‐nHAP+GelMA promotes mandibular bone regeneration in aged mice by remodeling the senescent immune microenvironment. Local delivery of Li‐nHAP restores lysosomal homeostasis in senescent macrophages, reduces intracellular labile Fe2+ accumulation, ROS production, and lipid peroxidation, thereby suppressing macrophage ferroptosis and senescence ...

Effects of different patterns of movement for correcting a deep curve of Spee with clear aligners on the anterior teeth: a finite element analysis

open access: yesBMC Oral Health
Objective To analyse the anterior teeth effects of clear aligners on five different patterns of mandibular molar movement and to define the most effective configuration to be implemented with clear aligners through finite element analysis.

Tooth row allometry in domestic rabbits and nondomestic lagomorphs: Evidence for a decoupling of body and tooth row size changes in evolutionary time

open access: yesThe Anatomical Record, EarlyView.
Domestic rabbits of different body sizes differ disproportionately in the length of their tooth row or the length of their diastema. Abstract In various domestic mammals, smaller breeds tend to have proportionally larger teeth, whereas this is not a universal trend across mammals.

Rethinking brachycephaly: Anatomical implications and health considerations in lagomorphs

open access: yesThe Anatomical Record, EarlyView.
Abstract Brachycephaly in domestic rabbits is increasingly perceived by welfare organizations as associated with significant health complications, particularly oral pathologies. Despite this perception, comparative anatomical research into rabbit brachycephaly is limited compared to that of dogs and cats, compelling an in‐depth examination of its ...

Pulpal Chamber Floor Thickness of First Molars in a Black South African Sample

open access: yesOral
Background/Objectives: Root canal procedures on multi-rooted teeth, including first molars, depend on experience, tactile perception, and anatomical knowledge to avoid perforation in the furcation region.

Changes in mandibular third molar angle and position after unilateral mandibular first molar extraction

open access: yes, 2006
Introduction: Third molars often become impacted because of lack of space for their eruption. Because the third molars play an important role occlusally, premolars or second molars are sometimes extracted to create space.

Cortical bone distribution in the human mandibular symphysis: Ontogenic and morphometric approaches in archeological context

open access: yesThe Anatomical Record, EarlyView.
Abstract The human mandibular symphysis concentrates multiaxial loads during function and remodels throughout growth, but the precise mechanisms underlying cortical bone shape during growth remain relatively unexplored. Approaches based solely on thickness or external cortical contours provide only partial insights and do not capture the functional ...
