Introduction: The negative impact of inhaled antiasthmatic drugs (IAD) on oral health is reflected primarily in the increased incidence of caries in asthmatic children compared to healthy children. It is believed that one of the causes of the increased incidence of caries in asthmatic children is from bronchodilator effect in reduced secretion of saliva. Decreased salivation favors bacterial colonization and studies have shown that the concentration of Streptococcus mutans, a bacterium that has the primary role in the development of caries, is higher in asthmatic than in healthy children.
Material And Methods: The study sample consisted of 200 patients, age from 7-14 years, divided into two groups: control group (n1 = 100) consisted of healthy children and the experimental group consisted of children suffering from asthma (n2 = 100). In both groups of respondents are identified the DMFT values, the concentration of Streptococcus mutans, the amount of stimulated saliva and plaque index value.
Results: It was found that there are significant differences in the values of plaque index, salivary index and streptococcus mutans between the control and experimental groups (p> 0.05 for each of the examined variables). Those in the control group had significantly higher DMFT index than subjects in the experimental group (p = 0.004).
Conclusion: IAD does not cause reduced saliva production and thus do not represent a factor favoring increased concentration of Streptococcus mutans.

Aims: To quantitatively detect S. mutans, Bifidobacterium, and S. wiggsiae in occlusal biofilm from permanent first molars based on the Visible Occlusal Plaque Index (VOPI), and to analyse the association between their levels and the occlusal enamel caries occurrence following the diagnosis of the International Caries Detection and Assessment System (ICDAS).

The fungus Candida albicans is a prominent cariogenic fungal agent that works in association with Streptococcus mutans to accelerate the formation of oral cancer and tooth decay. This study evaluates caffeine-encapsulated titanium oxide nanoparticles (CF-TiO2 NPs) for their potential to prevent biofilm formation on teeth and enhance oral anticancer treatment by influencing apoptotic gene regulation. The synthesized CF-TiO2 NPs were characterized using UV, SEM, EDAX, and FTIR analyses, and their antioxidant activity was confirmed through free radical quenching studies.

Statement Of The Problem: Antimicrobial photodynamic therapy (aPDT) is a protocol proposed for reduction of bacterial load in deep dentin caries in primary and permanent dentitions. However, considering the difference in the morphology of dentinal tubules in primary and permanent teeth, the effect of this treatment may be different on the two dentition types.
Purpose: This systematic review and meta-analysis aimed to assess the effect of type of dentition as a determinant of microbial load reduction by aPDT in deep dentin caries.

Introduction: Biosurfactants are naturally occurring compounds with various ap-plications, biodegradable, non-toxic, and effective in different conditions. This study fo-cuses on the extraction and evaluation of biosurfactants produced by five strains of lactic acid bacteria [LAB] for their potential to inhibit biofilm formation and adhesion by Strep-tococcus mutans.
Methods: The strains of LAB-producing biosurfactants such as Lactobacillus salivarius, L.

Objective: The aim of the study is to study the degree of adhesion of reference strains of microorganisms to the surface of modern polymer materials for the manufacture of removable prostheses.
Materials And Methods: The primary and residual microbial adhesion of 4 types of polymers was studied: acrylic polymer (Villacryl H Plus), monomerless polymer (Vertex ThermoSens), photopolymers for additive manufacturing (Harz Labs Dental Denture Base, Harz Labs Dental Sand). , , , and were used as reference strains.
