Periodontal diseases, including gingivitis and periodontitis, have been described as inflammation of the supporting tissues of the teeth. The main cause of periodontal disease is dental plaque. If dental plaque is not eliminated of dental surface, mineralized dental plaque (calculus) occur. The mineralization process of calculus is similar to that of other ectopic calcifications, such as kidney stones and gallstones. The presence of a certain type of microorganism discovered during the last decade in various pathogenic calcification such as renal stones, atherosclerotic plaques. This microorganism is nanobacterium that has unique characteristics in different regards. Nanobacteria appear as self-propagating calcifying macro-molecular complexes found in bovine and human blood and blood products. The fact that nanobacteria is present in various pathogenic calcification incidences in the body and that it is responsible for the formation of calcification may remind us the hypothesis that it may be present in dental calculus which has a similar mineralization formation process and that it may play an efficient role in the calcification of dental calculus. Thus, nanobacteria may be considered to be a risk factor for the periodontal diseases providing that it has effect on the formation of dental calculus. The nucleating role of the microorganisms in the formation of dental calculus show similarities to that of nanobacteria in calcification. What is more significant is that the presence of an alkali environment is essential for nanobacteria to cause calcification as is the case for dental calculus to occur. These significant conditions support the idea that nanobacteria may be present in the formation and in the contents of dental calculus. Unfortunately, there are only few studies on nanobacteria conducted in the field of dentistry. It is not known whether or not dental plaque is associated with nanobacteria. A study may reveal the fact whether nanobactera are really a new bacteria species or they were the bacteria previously found and given a different name, but not yet proved to be involved in calcification. Nanobacteria may be proved to be a helpful criterion in explaining the relation of nanobacteria with periodontal disease formation.

Objective: This study aims to evaluate the clinical efficacy of electro-pneumatic intracorporeal lithotripsy for the treatment of salivary gland stones.
Study Design: A prospective cohort study of patients diagnosed with obstructive salivary gland syndrome, where basket-assisted sialendoscopy alone failed to remove the calculi.
Setting: This study was conducted at the "Queen Maria" Military Hospital in Brașov, Romania, and a private practice, between February 2023 and May 2024.

Background: Bacteria in physiological environments can generate mineralizing biofilms, which are associated with diseases like periodontitis or kidney stones. Modelling complex environments presents a challenge for the study of mineralization in biofilms. Here, we developed an experimental setup which could be applied to study the fundamental principles behind biofilm mineralization on rigid substrates, using a model organism and in a tailored bioreactor that mimics a humid environment.

Background: The oral and dental health and related quality of life of orphan children and adolescents-who are considered a vulnerable population-are critical for both individual and public health.
Objectives: This study aimed to investigate the status of the dental caries, oral hygiene, and dental treatment needs among a group of Turkish male orphan children and adolescents, as well as their impact on oral health-related quality of life.
Methods: A total of 112 orphan children and adolescents aged between 9 and 17 years living in a residential care facility in Istanbul, Türkiye, were involved in this cross-sectional study.

The development of laser technology has revolutionized dentistry, offering complementary and alternative approaches to traditional techniques. Lasers have been successfully integrated into various dental procedures, enhancing treatment outcomes and patient care. Several types of lasers can increase the acid resistance of enamel, thus preventing caries.

The genus Streptococcus is highly diverse and a core member of the primate oral microbiome. Streptococcus species are grouped into at least eight phylogenetically-supported clades, five of which are found almost exclusively in the oral cavity. We explored the dominant Streptococcus phylogenetic clades in samples from multiple oral sites and from ancient and modern-day humans and non-human primates and found that clade dominance is conserved across human oral sites, with most Streptococcus reads assigned to species falling in the Sanguinis or Mitis clades.
