Background: The application of herbal and/or chemical antimicrobial mouthwashes in addition to the mechanical methods of bacteria removal helps reduce the periopathogens and thus increase the periodontal tissues' health. The present study aimed to evaluate the antibacterial effect of Thymex (TMX) syrup on three periodontal facultative anaerobes in vitro and compare it with 0.2% chlorhexidine (CHX) mouthwash.
Methods: In this in vitro experiment, the disc diffusion method was used to measure the inhibitory halo diameter (IhD) of , , and . The paper discs containing TMX and CHX were placed on Mueller-Hinton agar media and cultured with the mentioned bacteria. Moreover, a blank disc containing distilled water was used as a control. From each of the three bacterial species, five samples were taken, and after 18 hours of storage in the incubator, the IhDs were measured in millimeters. A one-way ANOVA test and an independent sample -test were used to compare the mean differences of IhDs between groups. The significance level was considered to be 0.05.
Results: The IhDs ranged between 6.2-8.8 mm and 12.3-34 mm for TMX and CHX, respectively. CHX showed a more inhibitory effect on all three species of bacteria compared to TMX mouthwash ( < 0.001).
Conclusions: Despite the inhibitory effect of TMX on bacterial growth, CHX showed significantly more antibacterial activity than TMX against three studied bacterial species.

Background: Impression materials can harbour microorganisms from saliva and blood, posing cross-contamination risks. However, post-setting disinfection might compromise the dimensional accuracy and mechanical properties of alginates. Hence, it was the aim of this research to assess the detail reproduction, tear strength, elastic recovery, and surface quality of the gypsum model of newly developed dental alginates with inherent antimicrobial properties.

Background: Removal of the microbial deposits (plaque and calculus) by performing effective scaling and root planing (SRP) is the fundamental step for managing periodontal disease (gingivitis and periodontitis). Various adjuncts in the form of mouthwash, gels, and toothpaste are also being used as adjuncts to SRP for managing periodontitis. Recently, ( ), commonly known as goji berry or wolfberry, has gained popularity for managing chronic inflammatory and infectious diseases.

Article Synopsis
- The study aimed to examine the demographic, maternal, and perinatal factors linked to hospitalizations of moderately to late preterm and term neonates within 72 hours of birth in Malawi's Dedza and Mangochi districts.
- Various factors were analyzed using a case-control method, comparing sick neonates admitted to intensive care with healthy ones, with data collected through case files and caregiver interviews.
- Results indicated that certain practices, like using tetracycline eye ointment and proper umbilical cord care, reduced hospitalization odds, while factors such as low birth weight and poor Apgar scores significantly increased hospitalization risks.

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.

Article Synopsis
- A clinical trial was conducted to evaluate the effectiveness of 0.2% chlorhexidine digluconate (CHX) and 8.7% choline salicylate (CHS) in healing oral mucosa lesions in patients receiving new partial removable dentures (PRDs) compared to a control group with no treatment.
- Twenty-seven healthy patients participated, and the healing progress was monitored through measurable wound surface area (WSA) over 14 days using intraoral images.
- Results showed that CHX led to the quickest reduction in WSA after 7 days (85.1%), followed by CHS after 10 days (70.1%) and the control group after 14 days (59.
