About this trial

This is an interventional diagnostic trial for Endodontic Disease focused on measuring Endodontic disease, Microbiome, Permanent teeth, Primary teeth

Eligibility Criteria

4 Years - 13 Years (Child)All SexesDoes not accept healthy volunteers

Inclusion Criteria:

  • have intact roots or <1/3 of physiological root resorption
  • have clinical crowns that permit effective rubber dam isolation
  • no mobility, fistula, pus discharge, gingival swelling, periapical abscess or internal resorption.

Exclusion Criteria:

Arm Description

For the disinfection of teeth, 30% hydrogen peroxide and 2.5% sodium hypochlorite solution were used for 30 seconds each. Then, 5% sodium thiosulfate solution was used to inactivate the disinfectant agents. Cavity preparation and root canal access were accomplished using sterile high-speed diamond burs under water cooling. Microbial samples were taken immediately by the same researcher from the largest root canal under strict aseptic conditions by using paper point method. Sterilized minimum four paper points were placed to the same level in root canal and the root canal content was absorbed. Each paper point was kept into the canal for at least 30 seconds. Then, paper points were placed into the Eppendorf tubes and refrigerated at -80 °C within 10 min.

5. Study Description

Brief Summary
Recognition of community profiles in endodontic infections may allow a better understanding of the pathogenesis of the disease and the establishment of more effective treatment protocols. Therefore, the aim of the present study was to investigate bacterial diversity in endodontically infected primary and permanent teeth using 16S rRNA gene sequencing and QIIME 2TM (Quantitative Insights Into Microbial Ecology 2) bioinformatics pipeline
Detailed Description
Endodontic infections are defined as an infection of the pulp and periapical tissues. This infection is caused by microorganisms that invade the pulp via dental caries or dental trauma. In these mixed population infections, anaerobic bacteria have been reported to be conspicuously dominant and the number of microorganisms per canal may vary. Traditionally, the endodontic microbiome has been identified by culture-based (phenotype-based) techniques. Inability to cultivate approximately 40-55% of bacteria in the endodontic microbiome, bias or inexperience of researchers may limit the results of cultural research. Microbiome-based new generation sequencing (NGS), which was initially used in ecological studies, has been widely used in recent years to identify bacterial diversity using the 16S ribosomal RNA (rRNA) gene in endodontic infections microbiome, bias or inexperience of researchers may limit the results of cultural research. There are few studies investigating the endodontic microbiome in primary teeth. However, to the best of our knowledge, to date, there is no metagenomic study that investigates the endodontic microbiome of the primary and permanent teeth. It is a still question of whether there is a difference in the endodontic microbiomes during the mixed dentition period when both dentition types can be seen.
