Caries Incidence in School-Based Prevention Programs in the Presence of Interval Censoring.

Background/objectives: School-based caries prevention can increase access to critical dental services and reduce oral health inequities. However, little is known regarding the incidence of dental caries in children participating in school caries prevention, and caries diagnosis is often interval censored.

Methods: In this paper, we used data from a longitudinal, school-based, randomized clinical trial of minimally invasive treatments for dental caries to estimate the per-visit incidence rate and compare the hazard of dental caries in children receiving either silver diamine fluoride or glass ionomer dental sealants.

The impact of inactivation of the GH/IGF axis during aging on healthspan.

Several mouse lines with congenital growth hormone (GH)/insulin-like growth factor-1 (IGF-1) axis disruption have shown improved health and extended lifespan. The current study investigated how inactivating this axis, specifically during aging, impacts the healthspan. We used a tamoxifen-inducible global GH receptor (GHR) knockout mouse model starting at 12 months and followed the mice until 24 months of age (iGHRKO mice).

Development of primary osteoarthritis during aging in genetically diverse UM-HET3 mice.

Background: Primary osteoarthritis (OA) occurs without identifiable underlying causes such as previous injuries or specific medical conditions. Age is a major contributing factor to OA, and as one ages, various joint tissues undergo gradual change, including degeneration of the articular cartilage, alterations in subchondral bone (SCB) morphology, and inflammation of the synovium.

Methods: We investigated the prevalence of primary OA in aged, genetically diverse UM-HET3 mice.

Targeting mitochondrial dysfunction using methylene blue or mitoquinone to improve skeletal aging.

Methylene blue (MB) is a well-established antioxidant that has been shown to improve mitochondrial function in both and settings. Mitoquinone (MitoQ) is a selective antioxidant that specifically targets mitochondria and effectively reduces the accumulation of reactive oxygen species. To investigate the effect of long-term administration of MB on skeletal morphology, we administered MB to aged (18 months old) female C57BL/J6 mice, as well as to adult male and female mice with a genetically diverse background (UM-HET3).

Noninferiority of Silver Diamine Fluoride vs Sealants for Reducing Dental Caries Prevalence and Incidence: A Randomized Clinical Trial.

Importance: Dental caries is the world's most prevalent noncommunicable disease and a source of health inequity; school dental sealant programs are a common preventive measure. Silver diamine fluoride (SDF) may provide an alternative therapy to prevent and control caries if shown to be noninferior to sealant treatment.

Objective: To determine whether school-based application of SDF is noninferior to dental sealants and atraumatic restorative treatment (ART) in the prevalence of dental caries.

Unmet Dental Needs in Children Following Suspension of School-Based Oral Health Services Due to COVID-19.

Background: Dental caries (tooth decay) is the world's most prevalent noncommunicable disease and can lead to pain, infection, and edentulism. Many children with caries lack access to traditional dental services. School-based caries prevention can increase access to care and reduce health inequities.

Development of primary osteoarthritis during aging in genetically diverse UM-HET3 mice.

Dental erosion as an indicator of gastroesophageal reflux disease.

While evidence shows that dental erosion (DE) is often caused by gastroesophageal reflux disease (GERD), the relationship of DE severity to a patient's symptoms and receipt of appropriate medical treatment for GERD is not clearly understood. The purpose of this study was to evaluate the association between DE and GERD. Eighty participants underwent a Basic Erosive Wear Examination for DE and completed the Patient-Reported Outcomes Measurement Information System (PROMIS) survey on symptoms of gastrointestinal reflux (PROMIS Scale v1.

Lifelong Excess in GH Elicits Sexually Dimorphic Effects on Skeletal Morphology and Bone Mechanical Properties.

Excess in growth hormone (GH) levels, seen in patients with acromegaly, is associated with increases in fractures. This happens despite wider bones and independent of bone mineral density. We used the bovine GH (bGH) transgenic mice, which show constitutive excess in GH and insulin-like growth factor 1 (IGF-1) in serum and tissues, to study how lifelong increases in GH and IGF-1 affect skeletal integrity.
