Purpose: The aim of the study was to estimate the salivary levels of Streptococcus mutans, Lactobacilli and Actinomyces and to correlate it with dental caries experience in mixed and permanent dentition.
Materials And Methods: The sample size comprised 110 subjects. The decayed, missing and filled teeth (DMFT) index of all the individuals participating in the study was calculated. Saliva samples were collected from patients and samples were inoculated on specific culture media and incubated for a period of 48 h. Based on colony characteristics, S. mutans, Lactobacilli and Actinomyces were identified.
Results: A positive correlation exists between DMFT and S. mutans, Lactobacilli and Actinomyces in mixed dentition and permanent dentition group samples (P < 0.001).
Conclusion: The conclusion from the results obtained was that S. Mutans, lactobacilli and Actinomyces which are the components of the normal microbial flora of the oral cavity play an important role in the pathogenesis of dental caries and increased number of microorganisms is associated with an increased caries frequency.

Objectives: Lactobacilli and Streptococcus mutans are stigmatized as cariogenic bacteria, but few studies have simultaneously examined the quantitative and qualitative aspects of lactobacilli and S. mutans in childhood dental caries. Therefore, this study aimed to detect the presence of S.

Background: and play an important role in the etiopathogenesis and progression of dental caries (DC). Their quantification and identification may be helpful for epidemiological and early intervention measures.
Objectives: We conducted the study to evaluate the colony counts of and with the location of DC and correlate their prevalence with the age of the patient.

The study aimed to assess the impact of combining potassium iodide (KI) with methylene blue (MB) in antimicrobial photodynamic therapy (aPDT) within an oral biofilm formed in situ. A single-phase, 14 days in situ study involved 21 volunteers, who wore a palatal appliance with 8 bovine dentin slabs. These slabs were exposed to a 20% sucrose solution 8 times a day, simulating a high cariogenic challenge.

Objective: To compare caries-related microorganisms and candida in complete cleft infants with normal palate infants.
Methods: The case-control study was conducted from April 2021 to January 2022 at the College of Dentistry, University of Baghdad, Baghdad, Iraq, and comprised infants with age ranging from 1 day to 4 months. They were divided into complete cleft group A and control group B.

Objective: To assess the presence of () and species () of newborn-mother pairs using the real time polymerase chain reaction (qRT-PCR).
Method: Subjects were selected from the patients followed in the Neonatology Clinic of Akdeniz University's Faculty of Medicine between the years 2017-2018. First samples collected within 48 hours after birth, and second samples were at six months.
