Background: In this COVID era, it's critical to promote nonaerosol procedures. Atraumatic restorative treatment (ART) is one of them, and it's particularly effective in children for lowering anxiety, enhancing dental health, and giving restorative care.

Aim: The aim of this study was to assess the survival rate of ART compared with conventional treatment procedures in primary dentition.

Materials and methods: The review was done in accordance with the Preferred Reporting Items for Systematic reviews and Meta-analysis statement and is been registered in PROSPERO (CRD42021213729). The studies included comprised clinical investigations with randomized controlled trials (RCTs) which compared the survival rate of ART and conventional restorative treatments using the same or different restorative materials to treat carious lesion. RCTs in which ART was compared with conventional treatment on patients in the age group of 6-10 years with minimum follow-up of 6 months. Studies available as open access and free full text in PubMed, DOAJ, and Google Scholar databases, and published in English Language only were included in the study. Cochrane's collaboration tool for RCTs was used for the assessment of risk of bias.

Results: The survival rate of single surface and multiple surface in primary dentition treated according to the ART compared with conventional treatment was found to be similar.

Conclusion: The ART approach is equally helpful in managing dental caries in children and this method may be considered a useful intervention in clinical practice to enhance the dental health of children.

Background: A lot of videos on root canal treatment in children are available on YouTube™ but no quality checks are present. Addressing this is critical so that parents and dentists know why root canal in children is important including the explanation of procedural steps regarding treatment undertaken.

Aim: The aim of this study is to analyze and grade YouTube™ videos on root canal treatment in children and assess whether it provides beneficial information for patients and dentists.

Materials and methods: Variables such as number of views, duration (minute), days since upload, number of comments, number of likes, number of dislikes, interaction index, and viewing rate were tabulated for selected 57 videos.

Statistical:

Analysis: Selected videos were statistically analyzed using a 15-point scoring system and evaluated using SPSS software. Finally, the obtained data sets were classified as low-, moderate-, and high-content videos. Fisher's exact test was used to compare between proportions.

Results: Based on the tabulated variables, most of the videos were low (n = 31) and moderate content (n = 24), which dentists mostly uploaded. There was no statistical significance between the video types and content score groups (P > 0.05). The most frequently mentioned issues were procedure (84.21%), obturating materials (75.44%), and etiology (63.16%). The least mentioned subjects were indications (24.56%) and importance (22.81%).

Conclusion: From this study, YouTube™ videos on root canal treatment in children were of low and moderate quality. Hence, high-quality videos are essential for providing awareness among patients and dentists.

Context: Cleaning and shaping of the canals damages the root dentin which becomes a gateway to dentinal cracks and thereby causes failure of the treatment.

Aim: The aim of this study was to assess and compare dentinal crack formation caused by three different nickel-titanium (NiTi) rotary file systems in primary anterior teeth.

Settings and design: The present in vitro study is an experimental, comparative study.

Materials and methods: One hundred fifty extracted primary anterior teeth were included in this study. The teeth were randomly divided into five groups. Group 1: Pedoflex rotary file system, Group 2: Prime Pedo^™ rotary file system, Group 3: Kedo-S² rotary file system, Group 4: K-files, and Group 5: no instrumentation. Roots were sectioned and viewed under a stereomicroscope for the presence of any cracks.

Statistical analysis used: The data were analyzed using the Chi-square test and Kruskal-Wallis test.

Results: In the coronal, middle, and apical thirds, Group 2 showed a maximum number of crack formations in the middle third (57%), followed by Group 3 (43.3%) and Group 1 (36.7%). Groups 4 and 5 showed no crack formation in all the root sections. The middle third showed a maximum number of crack formations compared to the coronal and apical thirds.

Conclusions: Rotary systems render various benefits with an acceptable success in comparison to conventional hand instrumentation. Within the limitation of this study, it was found that Pedoflex rotary file system was the best with the least number of crack formations.

Background: Managing anxiety in children during the pandemic will be a concern for many pediatric dentists.

Aim: The aim of this study was to assess the anxiety levels in children aged between 4 and 9 years about the pediatric dentists donning a personal protective equipment (PPE) for dental treatment during the COVID-19 pandemic era in Bengaluru.

Materials:

And:

Methods: The study was done in two parts with a sample size of 100 each. The first part was a questionnaire-based survey addressed to the pediatric dentists practicing in Bengaluru. The second part of the study was clinical assessment of dental anxiety at three time intervals (T1, T2, and T3) using the animated emoji scale.

Results: The study revealed that 87% use preprocedural behavior management post-COVID. Majority of the dentists donned the PPE before conditioning the child (59%) and 41% wore the PPE after conditioning the child. The mean anxiety level in the study children showed an increase in anxiety level at T2 of 3.58 (P < 0.001 ± 1.32) in children aged 4-6 years when compared to T1 and T3 of 3.27 (P < 0.001 ± 1.64) and 3.07 (P < 0.001 ± 1.32), respectively.

Conclusion: Children aged between 4 and 6 years showed increased levels of anxiety compared to the 7-9-year age group to the pediatric dentists donning a PPE during treatment in the COVID-19 pandemic. Pediatric dentists also showed a satisfactory knowledge regarding disinfection and fumigation procedures.

Background: A number of media that create the best possible conditions to maintain periodontal ligament (PDL) cell viability after dental avulsion have been reported.

Aim: The aim of this study is to evaluate ice apple water (IAW), Aloe vera, and propolis as a storage medium to preserve the viability of human PDL fibroblasts.

Methods: An in vitro comparative type of study was performed on a PDL cell culture model. PDL fibroblasts obtained from the roots of healthy premolars were cultured in Dulbecco's Modified Eagle's Medium (DMEM) and treated with ice apple water (IAW), 7% propolis extract (PE), 30% Aloe vera extract (AVE), positive control DMEM supplemented with fetal bovine serum, negative control (NC) without any agent, and incubated at 37°C for 1 h, 3 h, and 24 h. Cell viability was assessed using 3-(4,5-dimethylthiazol-2-yl)-2,5-diphenyl tetrazolium bromide assay after every test period. Optical density was measured at a wavelength of 490 nm.

Statistical analysis used: The effects of the test storage media were evaluated by one-way analysis of variance test, followed by post hoc Tukey's multiple comparison test (P < 0.05).

Results: Seven percent PE demonstrated the highest capacity of maintaining PDL cell viability at 1 h and 24 h. IAW showed a statistically significantly lower percentage of viable cells at all three test periods as compared to 7% PE. After 3 h, 30% AVE demonstrated maximum viable cells.

Conclusions: Within the limitations of this study, propolis at a concentration of 7% was the most effective medium for maintaining PDL cell viability.

Aim: This study aimed to investigate the conditioning effects of phosphoric acid/5.25% sodium hypochlorite (NaOCl) mixture, 2% chlorhexidine (CHX) digluconate, and 10% polyacrylic acid on cavosurface microleakage and bond strength of glass ionomer (GI) restorations.

Materials and methods: Out of 68 extracted premolars, 34 teeth were selected for microleakage and 34 for bond strength evaluation. The samples were divided into the following four groups. Group 1: pretreatment with 50/50 volume% mixture of 5.25% NaOCl solution and 37% phosphoric acid (H₃PO₄), Group 2:pretreatment with 2% CHX digluconate, Group 3: pretreatment with 10% polyacrylic acid (positive control), and Group 4: no pretreatment (negative control). All the samples were then restored with glass ionomer cement (GIC). Microleakage was evaluated using a stereomicroscope and rhodamine-B dye penetration test. For bond strength, flat dentin surface was exposed and pretreated as mentioned previously and restored with GIC and was evaluated using universal testing machine.

Results: Among all the four groups, Group 1 showed least microleakage and highest bond strength when compared with other groups. Whereas the Group 4 samples which were not pretreated with any of the conditioning agent showed the least shear bond strength with greatest cavosurface microleakage when compared to the groups which were pretreated with the conditioning agents.

Conclusions: A combination of 50/50 volume % mixture of 37% H₃PO₄ and 5.25% NaOCl can be a good choice for surface pretreatment of GI restorations.

Background: Direct pulp treatment is carried out when a healthy pulp gets mechanically/accidentally exposed during the operative procedures or trauma.

Aim: To determine the effects of various direct pulp capping materials as measured by the clinical and radiographic analysis.

Design: Two reviewers performed a database search of the studies published between January 2005 and November 2020. The inclusion criteria were papers published in the English language; children aged 3-12 years having deep carious lesions in primary teeth. All potential studies were acknowledged by their title and abstract. The full-text analysis of potentially relevant studies, the selected studies were included in the systematic review. A meta-analysis calculation was performed for the overall data and the subgroup data.

Results: The database searching led to 57 articles, which were of direct pulp treatment in primary teeth, after the removal of duplicates, 55 records remained but did not meet all inclusion criteria. A high variability was observed among the papers. Further filtering with criteria led to nine articles, which met all inclusion criteria. Meta-analysis demonstrated the success rates of DPT in primary teeth (95% confidence interval -0.799-0.898); P < 0.001. Clinical assessments of various direct pulp capping materials suggested 84.9% of success irrespective of the material used. The nine studies were heterogeneous according to the random effect model (P < 0.001, I² = 84.08%).

Conclusions: Direct pulp treatment has the advantage of being a conservative vital pulp therapy reducing the need for a more invasive treatment.

Aim: The aim is to assess the impact of socioeconomic factors on deciduous teeth eruption among infants born after low-risk pregnancy and infants diagnosed with intrauterine growth restriction (IUGR).

Materials and methodology: The cross-sectional study included 110 neonates recruited at birth using stratified random sampling based on inclusion and exclusion criteria. Neonates diagnosed without IUGR were allocated to Group I (n = 55) and those diagnosed with IUGR were allocated to Group II (n = 55). The perinatal case history was recorded, followed by intraoral examination at birth, 6 months, and monthly up to 1 year or till first evidence of teeth eruption.

Results: The difference between both groups based on socioeconomic status (SES) was found statistically significant (P = 0.043). The first evidence of eruption of deciduous teeth was found delayed in Group II (P = 0.0001). Secondary school education was found statistically significant between both the groups (P = 0.024). The difference between the two groups based on religion (P = 0.353) and gravidity (P = 0.571) was found statistically insignificant.

Conclusion: Lower SES and secondary maternal education can be considered statistically significant risk factors of IUGR and delayed deciduous teeth eruption. No correlation of IUGR with religion and gravidity was found.

Introduction: The root canal system in primary molars is considered to be complex. The aim of the present study was to assess the morphology of roots and root canals of primary maxillary and mandibular second molars using the cone-beam computed tomography (CBCT).

Materials and methods: From a total of 104 collected primary maxillary and mandibular molars (51 maxillary second molars and 53 mandibular second molars), 60 teeth (30 each of maxillary and mandibular second molars) were selected randomly and accordingly assigned into two groups: MAX2M (primary maxillary second molars) and MAN2M (primary mandibular second molars). CBCT was used to assess the number of roots and root canals, length of root, mesiodistal and buccolingual width of the canal, shape of the canal, and intercanal communications. Descriptive statistical analysis was performed using the SPSS software version 17.0.

Results: The mandibular second molars showed the presence of two roots in 27 sample molars while the presence of three roots was observed in three MAN2M group. In these molars, all three roots exhibited Type I root canal configuration. The maxillary second molars exhibited three roots. A total of nine intercanal communications were seen in MAX2M group, whereas two communications were seen in MAN2M group. The palatal root in MAX2M group was more angulated (mean value: 127.21 ± 9.10) as compared to mesial (mean value: 95.39 ± 8.64) and distal roots (114 ± 11.24).

Conclusion: The comprehensive knowledge of root and canal morphology of primary molars and anatomic variations is essential for successful endodontic therapy.
