Idiopathic gingival papillokeratosis with crypt formation (IGPC) is a new and a very rare benign entity, clinically characterized by white-yellowish plaques with papillary architecture located in the upper labial gingiva of adolescent patients. The condition generally exhibits a bilateral symmetrical distribution and is asymptomatic. We report two new cases, one with a classic presentation and the other in an older individual.

Saliva has emerged as a promising diagnostic fluid for viral infections, enabling the direct analysis of viral genetic material and the detection of infection markers such as proteins, metabolites, microRNAs, and immunoglobulins. This comprehensive review aimed to explore the use of saliva as a diagnostic tool for viral infections, emphasizing its advantages and limitations. Saliva stands out due to its simplicity and safety in collection, along with the convenience of self-collection without the need for healthcare supervision, while potentially being comparable to urine and blood in terms of effectiveness.

Reactive arthritis is an extremely rare spondyloarthritis that affects the peripheral joints and spine, resulting in common symptoms such as arthritis, urethritis, conjunctivitis, and mucocutaneous lesions. On rare occasions, oral lesions such as circinate erosions on the hard and soft palate, gums, tongue, and cheeks may occur. Reactive arthritis may develop during or after genitourinary or gastrointestinal bacterial infections such as Shigella, Salmonella, Yersinia, and Chlamydia.

Background: Burning mouth syndrome (BMS) it is characterized by burning and uncomfortable sensations with no clinical alterations or laboratory findings. The evaluation of the salivary characteristics of people with BMS can help the understanding of the pathogenesis of this condition. This case-control study aimed to trace the salivary profile of women with burning mouth syndrome (BMS).

Ethnopharmacological Relevance: The antimicrobial potential of propolis - a honey bee product - was correlated with its traditional use as a natural medicine, mainly known for antimicrobial and antioxidant properties. Moreover, research on natural products in dentistry has increased in recent years in the search for products with greater therapeutic activity, lower toxicity, better biocompatibility, and more affordable cost to the population.

Objective: Considering that the beneficial effect of propolis is acknowledged for several oral conditions, this study aimed to synthesize the research and technological forecasts of existing evidence on the use of propolis extract as a potential antimicrobial agent in dentistry.

Objectives: To conduct a systematic review of the literature to evaluate the methodological aspects of population-based studies on the prevalence of oral mucosal lesions (OMLs).

Methods: Two reviewers independently conducted a literature search in three databases (PubMed, Web of Science and Scopus) and extracted data using a standardized form. Data on the following characteristics of the included studies were collected: sample size; age of participants; references used to define the diagnostic criteria, training of the examiners, and data collection; type, grouping and characteristics of the lesions; and lesions excluded and measures of agreement between examiners.

Background: Diabetes mellitus (DM) is a chronic disease of the carbohydrate metabolism that, when not rigorously controlled, compromises systemic and organ integrity, thereby causing renal diseases, blindness, neuropathy, arteriosclerosis, infections, and glandular dysfunction, including the salivary glands. The aim of this study was to determine the relationship between the qualitative and quantitative parameters of salivary alteration, which are indicators of salivary gland dysfunction, and the level of metabolic control of type 2 diabetes patients.

Material And Methods: A convenience sample of 74 voluntary patients with type 2 DM was selected, each of whom donated a sample of unstimulated saliva.

Unlabelled: The aim of this study was to determine the relative frequency and distribution of reactive hyperplastic lesions (RHL) of the oral mucosa at the Oral Pathology Institute of the School of Dentistry at the University of Chile. This was a retrospective study of 1149 biopsies with histopathological diagnosis of RHL, performed between 2000 and 2011. The RHL were classified in 4 groups: fibrous hyperplasia (FH), pyogenic granuloma (PG), peripheral giant-cell granuloma (PGCG) and peripheral ossifying fibroma (POF).
