Reptilian dentition is diverse, categorized into homodont and heterodont types based on tooth shape and function. Certain reptiles have evolved unique teeth for specific diets, such as iguanas' peg-like teeth for grinding plants and venomous snakes' fangs for injecting venom. The attachment of teeth varies: acrodont and pleurodont teeth are fused to the jaw, while thecodont teeth are embedded in sockets. Oral examinations reveal conditions like stomatitis, abscesses, or foreign bodies caused by bacterial infections. Diagnosis involves clinical and laboratory assessments, while treatment involves supportive care and preventing secondary infections. Proper husbandry and regular veterinary checks are critical for prevention.

Objectives: The aim of this study is to explore the specific application scenarios of quantitative light-induced fluorescence (QLF) in the detection and treatment of early caries, so as to provide more evidence for the clinical application of QLF.
Methods: (1) The accuracy of QLF in detecting the lesion depth of early caries was evaluated by combining transverse microradiography (TMR) and spectrophotometer analysis (n=6). (2) Resin infiltration therapy was used as a representative method for the treatment of early caries to evaluate the ability of QLF in assessing the therapeutic effect on early caries (n=6).

Objectives: to evaluate the effect of smear-layer deproteinization using papain gel and SPRG-adhesive on marginal-gap, anti-demineralization of enamel and dentin after chemical pH cycling and assess acid-base resistance zone (ABRZ) characteristics.
Methods: Cylindrical cavities were prepared cervically in thirty-two extracted premolars. Teeth were divided into two pretreatment groups (n=16); deproteinization with papain enzyme gel (Papacarie Due, Brazil) for 60 second, and no-deproteinization.

In orthopaedic surgical procedures, bone cutting is often performed with an oscillating saw. Achieving an optimal cut requires high accuracy, low temperature, minimal surgeon effort, and time efficiency, all of which may be influenced by the forces applied on the sawing device, and the microstructure of the cut bone. The relation between bovine bone microstructure and sawing forces has been studied.

The fundamental cause theory posits social factors as causes of disease as they encompass access to important resources such as knowledge, wealth, and social networks. While these social factors have been consistently associated with oral and systemic diseases, causality remains unestablished. Here, we estimated the causal effect of social adversity, comprising low economic and social capital, on the development of (1) oral conditions (OC) and (2) multimorbidity including oral conditions (MIOC) in a cohort of middle-aged and older adults over a 7-y period and assessed whether effects varied by age or gender.

Objectives: To examine bidirectional associations between dental caries and body mass index (BMI) among adolescents living in vulnerable communities in Brazil.
Methods: In a cohort study involving adolescents (n=323), BMI, number of decayed teeth and odontogenic infections (PUFA/pufa index) were recorded at three time points between 12 and 15 years of age. Trajectories of dental caries, odontogenic infections, and BMI were developed using group-based trajectory modelling.
