Decreased salivary flow results in a clinically significant oral imbalance that may manifest as increased caries, susceptibility to oral candidosis, altered taste sensation, or a host of other problems. This article reviews the role of saliva in oral health, highlights the causes and consequences of xerostomia, and outlines treatment modalities for patients with xerostomia. Journal articles were investigated through Medline, and relevant textbooks and handbooks were consulted. A summary of the literature pertinent to clinical prosthodontics is presented.

Purpose: Tick diversity in Algeria has garnered increasing interest due to its implications for animal health and zoonotic diseases. Recent reports of abnormal ulcerative lesions in goats and sheep in the Cheria region of northeastern Algeria have raised concerns about a potential association with tick infestations. The aim of this study is to hypothesize the potential involvement of ticks in these unusual lesions.

Electrochemical aptamer-based biosensors (E-aptasensors) are emerging platforms for point-of-care (POC) detection of complex biofluids. Human saliva particularly offers a noninvasive matrix and unprecedented convenience for detecting illicit drugs, such as cocaine. However, the sensitivity of cocaine E-aptasensors is significantly compromised in saliva.

The use of Raman spectroscopy, particularly surface-enhanced Raman spectroscopy (SERS), offers a powerful tool for analyzing biochemical changes in biofluids. This study aims to assess the modifications occurring in saliva collected from patients before and after exposure to cone beam computed tomography (CBCT) and computed tomography (CT) imaging. SERS analysis revealed significantly amplified spectra in post-imaging samples compared to pre-imaging samples, with pronounced intensification of thiocyanate and opiorphin bands, which, together with proteins, dominated the spectra.

Hard ticks (family Ixodidae) are one of the most predominant arthropod disease vectors worldwide, second only to mosquitoes. In addition to harboring animal and human pathogens, ticks are known to carry a microbial community constituted of non-pathogenic organisms, which includes maternally inherited intracellular endosymbionts and other environmentally acquired extracellular microorganisms. These microbial communities, which include bacteria, viruses, protozoans, and fungi-with often commensal, mutualistic, or parasitic associations with the tick-comprise the tick microbiome, bacteria being the most studied community.

Pen-based oral fluids are used extensively for surveillance and disease detection in swine, but there is sparse information on the sampling process itself. To address this shortcoming, we documented the pen-based oral fluid sampling process with the aim of optimizing the number of pigs in a pen that contributed to the sample. We quantified the effects of (1) previous experience with rope sampling (training), (2) the number of ropes suspended in the pen, and (3) sampling time on pig participation and pig-rope contact.
