The potential of reuterin derived from Indonesian strain of against endodontic pathogen biofilms in vitro and ex vivo.

Objectives: Despite the use of common irrigating solution with antimicrobial properties, failed root canal treatment remains a significant problem in endodontics. In the present study, we examined the efficacy of reuterin derived from probiotic bacteria, on the biofilms of major endodontic pathogens using ex vivo model of root canal infections.

Methods: Biofilms of major endodontic pathogens namely , , and were formed on root canals of 60 human premolar tooth samples accordingly a standard protocol.

Short- term effect of probiotic consumption on the salivary microbiome profile of subjects undergoing orthodontic treatment with fixed appliances.

Objective: This prospective clinical study aim was to analyze the effect of the probiotic Lactobacillus reuteri Prodentis lozenges on salivary microbiome of subjects wearing fixed orthodontic appliances.

Methods: Saliva samples were collected prior to consumption and 14th-day post probiotic lozenges consumption (n=40, age 18-23). Oral hygiene index-score (OHI-S) and papilla bleeding index (PBI) were recorded.

Casein phosphopeptide-amorphous calcium phosphate fluoride treatment enriches the symbiotic dental plaque microbiome in children.

Objectives: The dysbiotic oral microbiome plays a key role in the pathogenesis of caries in children. Topical application of casein phosphopeptide-amorphous calcium phosphate containing fluoride (CPP-ACP/F) is an effective treatment modality for children with caries (CC). Hitherto the mechanism by which CPP-ACP/F modules the oral microbiome in CC has not been investigated.

Comparison of the accuracy of different impression procedures in case of multiple and angulated implants : Accuracy of impressions in multiple and angulated implants.

Background: There is no consensus in the literature regarding the impression procedures in the presence of multiple and angulated implants.

Methods: Three maxillary master models with 6 implants bilaterally positioned in anterior, premolar and molar regions were fabricated. In model 1, all implants were placed in parallel; in models 2 and 3, anterior implants were buccally inclined and posterior implants were distally inclined in 10- and 20-degrees, respectively.
