This study aimed to evaluate the dental students’ performance in ICDAS (International Caries Detection and Assessment System) coding with different levels of clinical experience.
Dental students (
= 122) in their clinical years, year 3 (
= 37), year 4 (
= 44), and year 5 (
= 41) received training (two-hour introductory lecture on ICDAS, followed by a 90 min e-learning video, and practice sessions using extracted teeth and photographs) from a calibrated expert. After training, the students examined a prevalidated set of extracted teeth and assigned scores in two sessions. The intra- and inter-examiner agreement between students was analyzed using weighted kappa statistics and a focus group discussion was conducted for qualitative feedback.
The range of kappa values for intra-examiner agreement among the year 3, 4, and 5 students for ICDAS caries code (0.611-0.879, 0.633-0.848, and 0.645-1.000) and restoration code (0.615-0.942, 0.612-0.923, 0.653-1.000), respectively. The range of kappa values foes them to detect caries in a reliable and reproducible manner irrespective of their past clinical experience and also significantly improves their caries detection skills.
The aim of this study was to assess the insertion torque of the mini-implant used in orthodontic patients and to assess the correlation between the insertion torque, primary stability, and perception of pain in patients undergoing orthodontic therapy with mini-implant-augmented anchorage.
Among the patients undergoing orthodontic therapy, 31 samples who required mini-implant for anchorage purpose were selected. A total of 59 mini-implants were placed in these patients. This included interradicular mini-implants and extra-alveolar mini-screws. Immediately after placement, the insertion torque in all these was measured using a digital torque meter and primary stability was assessed by identifying any mobility of the implant placed. Primary stability was noted at two time intervals immediate post-placement and 1 week after that. All the mini-implants that were considered in this study were immediately loaded. Patients were asked to record any pain experienced on the visual analog scale (VAS) score sheet at 2d break more often. Patients placed with extra-alveolar bone screws reported more pain than that of the smaller-dimension mini-implant.
The present study aimed to assess the sealing ability of various repair materials in furcation perforations using dye penetration.
A total of 80 human first molars from mandible with unbroken enamel surfaces, which were extracted completely for periodontal reasons, were chosen. All extracted teeth were kept in a sterile solution up until further use. see more Endo-access bur was used to prepare endodontic access cavity, and a high-speed long shank round bur was used to create a planned perforation on the floor of pulp. All the specimens were randomly grouped (20 teeth in each group) Group I control; group II Pro-Root MTA; group III resin-modified glass-ionomer cement (RM GIC); and group IV Biodentin. After placement of repair materials in perforated furcation, the chamber of each tooth was accessed with 2% methylene blue dye. Later, a diamond disk was used to split the teeth buccolingually. A stereomicroscope (10×) was used to visualize the highest dye penetration.
The least penetration was seen in teeth repairendodontic procedures have a remarkable damaging effect on prognosis and frequently result in loss of secondary periodontal attachment, thus resulting in early loss of the involved tooth. Therefore, the selection of biocompatible repair material aids to enhance the treatment prognosis.
This study aimed to compare the level of interleukin (IL)-10, IL-17, IL-27, IL-35, and IL-37 in the gingival crevicular fluid (GCF) and human plasma of subjects with periodontal disease.
In this cross-sectional study conducted over a 3-month period at a primary dental clinic in Malaysia, 45 participants were recruited via consecutive sampling and assigned into three groups, namely healthy periodontium group (
= 15), gingivitis group (
= 15), and periodontitis group (
= 15). Gingival crevicular fluid and plasma samples were collected from each participant. Enzyme-linked immunosorbent assay test was conducted to measure the concentration of IL-10, IL-17, IL-27, IL-35, and IL-37. Kruskal-Wallis H test was used to compare the interleukin levels between patient groups.
In GCF samples, IL-17 level was the highest in the periodontitis group (
<0.05), while IL-27 was the lowest (
<0.05). Meanwhile, plasma levels of IL-27 and IL-37 were significantly lower (
<0.05) in the periodontitis group, but plasma IL-35 levels were observed to rise with increasing disease severity.
There are reduced local and systemic levels of IL-27 in periodontitis patients.
Periodontal diseases exert both local and systemic effects, resulting in the destruction of the tooth-supporting structures and contributing to the systemic inflammatory burden. Some of the cytokines that were investigated in the current study, IL-17, IL-27, IL-35, and IL-37, can be potential biomarkers that warrant further longitudinal clinical studies to determine their usefulness as prognostic/diagnostic markers.

This study was done to assess the time to achieve the working distance based on the size of the glide path, operating kinetics, and the fracture resistance of different file systems.
One hundred and eighty mandibular premolars were divided into two groups of 90 each. Group I was subjected to continuous 360° rotary motion and group II to adaptive motion. Twisted File (TF) and Endostar E3 file methods were practiced in groups. The time (seconds) to achieving desired working length was recorded. Failures were classified as torsional failure or flexural failure.
The time taken by glide path size 15 in group I was 5.90 ± 4.06 seconds and in group II was 6.12 ± 4.16 seconds. The time taken by glide path size 20 in group I was 5.86 ± 3.12 seconds and in group II was 4.22 ± 2.10 seconds, with 25 size the time taken in group I was 5.32 ± 2.48 seconds and in group II was 3.16 ± 3.14 seconds. The time taken by group I was less as compared to group II, and the difference was significant (
< 0.05). There was a significant difference in time taken with different number files in both groups (
< 0.
