The literature discusses oral manifestations caused by sexually transmitted viruses: a narrative review.

This review provides practical recommendations for dental practitioners in dealing with oral lesions associated with sexually transmitted diseases (STDs), offering clinically relevant insights to increase the awareness of these diseases in the mainstream of everyday practice. STDs are acquired through unprotected vaginal, anal or oral sex and are caused by more than 30 different types of bacteria, viruses and protozoa. Saliva, precum, semen, vaginal secretions and menstrual blood could be likely vehicles of infections and defensive barriers to infection by pathogenic microbes could be represented via intact mucosal membrane, the diluent function of saliva, and the antimicrobial action of salivary enzymes that collectively contribute to oral health and protection.

The "Magnificent Seven" in Oral and Systemic Health against COVID-19.

The COVID-19 pandemic impacted all areas of daily life, including medical care. Unfortunately, to date, no specific treatments have been found for the cure of this disease, and therefore, it is advisable to implement all possible strategies to prevent infection. In this context, it is important to better define the role of all behaviors, in particular nutrition, in order to establish whether these can both prevent infection and improve the outcome of the disease in patients with COVID-19.

Investigation of the presence of Non-carious cervical lesions (NCCLs) in ancient adult skulls: analyzing data from prehistoric and historical samples through a systematic review and meta-analysis.

Objectives: Historically, the prevalence of caries has undergone significant changes, particularly increasing with the industrialization of sugar consumption. When examining ancient populations, lower caries rates are discovered, attributed in part to dietary factors. These populations consumed abrasive foods, leading to occlusal wear and reduced non-axial occlusal forces, potentially influencing Non-Carious Cervical Lesions (NCCLs).

Dentistry in the centuries: a historical overview.

The began of the dentistry as medicine's concept has a long history dating back to 7000 BCE, making it one of the earliest medical specialties. In its early days, dental diseases were often attributed to supernatural causes like "evil spirits" and "tooth worms." However, today, dentistry leverages cutting-edge technologies, including artificial intelligence, for diagnosis and treatment.

Possible uses of Hunter-Schreger bands of dental enamel for automated personal identification.

Background: Hunter-Schreger bands (HSB) are optical phenomena observed on tooth surfaces under polarized light, resulting from the intersection of enamel prisms. Anthropological studies demonstrate the prevalence of HSB in large mammals, contributing to enamel resistance. Historically, John Hunter and Schreger depicted HSB in dental literature.

Dietary Polyphenols against Oxidative Stress in Head and Neck Cancer: What's New, What's Next.

Head and neck cancers (HNC) are a worldwide health problem, accounting for over 5% of all types of cancers. Their varied nature makes it sometimes difficult to find clear explanations for the molecular mechanisms that underline their onset and development. While chemio- and radiotherapy are clearly not to be dismissed, we cannot undervalue the effect that polyphenols - especially dietary polyphenols - can have in helping us to cope with this medical emergency.

Alveolar Ridge Preservation with a Novel Cross-Linked Collagen Sponge: Histological Findings from a Case Report.

Alveolar ridge preservation (ARP) is a well-documented procedure to maintain bone volume after tooth extraction in order to place implants. However, at the end of the healing process, the residual biomaterial that is not reabsorbed remains embedded in the bone over time. Ribose cross-linked biomaterials demonstrated their ability to promote osteoconduction and complete resorption.
