The study is thus aimed to assess and compare the efficacy of Herbostra oil pulling mouthwash with Chlorhexidine mouthwash in reducing plaque accumulation around orthodontic brackets. A total of 20 patients were considered in this study randomly assigned into Group I (experimental group - Herbostra oil pulling mouthwash) and Group II (reference group-0.2% Chlorhexidine mouthwash). The plaque index scores were recorded in each individual at baseline (pre) and after 3 weeks (post). Dental plaque samples were collected around the orthodontic brackets at the cervical region of maxillary upper molars and lower incisors by cotton swabbing method and evaluated for the presence of microflora. Paired sample t-test for Streptococcus mutans count showed that statistically significant difference only within the group II (p=0.000) (Chlorhexidine group) and there was no significant difference within the group I (p=0.103) (Herbostra group). Paired sample t-test for plaque index score shows statistically significant difference within the groups (0.000).Independent t test showed statistically significant difference in the levels of  Streptococcus mutans count after 3 weeks between the two groups (p=0.000) with the mean values of (2.230±0.5056), (1.080±0.3458) in group I and group II respectively. From this study we concluded that, even though there was a reduction in plaque scores and S. mutans count with Herbostra oil pulling mouthwash but it was not as effective as Chlorhexidine mouth rinse.

ABSTRACT Objective: To evaluate the effects of different bleaching methods on the shear bond strength (SBS) of orthodontic brackets. Materials and Methods: Forty-five freshly extracted premolars were randomly divided into three groups (n  =  15 per group). In group I, bleaching was performed with the office bleaching method. In group II, bleaching was performed with the home bleaching method. Group III served as the control. Orthodontic brackets were bonded with a light cure composite resin and cured with an LED light. After bonding, the SBS of the brackets were tested with a Universal testing machine. Results: Analysis of variance indicated a significant difference between groups (P < .001). The highest values for SBS were measured in group III (20.99 ± 2.32 MPa). The SBS was significantly lower in groups I and II than in group III (P < .001). The lowest values for SBS were measured in group II (6.42 ± 0.81 MPa). SBS was significantly higher in group I than in group II (P < .001). Conclusions: Both of the bleaching methods significantly affected the SBS of orthodontic brackets on human enamel. Bleaching with the home bleaching method affected SBS more adversely than did bleaching with the office bleaching method.

Aim: To evaluate antibacterial, antifungal, antioxidant properties of custom-made natural tooth powder and the effectiveness of custom-made natural tooth powder on the oral hygiene status of children. Methodology: Antibacterial and antifungal properties were determined by agar diffusion method against Streptococcus mutans, Candida albicans and antioxidant properties were determined by DPPH (2,2-diphenyl-1-picryl-hydrazyl-hydrate) assay. Clinical trial included 60 children aged 8 to 11 years. Oral prophylaxis was done and after a washout period of 10 days, baseline Simplified Oral Hygiene index (OHI-S) scores, plaque scores and Streptococcus mutans colony counts were recorded. Children were randomly divided into two groups: Group I children brushed with custom-made natural tooth powder and Group II children used commercially available natural tooth powder twice daily. At the end of 30 days, post intervention data was collected and statistically analyzed. Results: In-vitro trial showed that the custom-made natural tooth powder exhibited both antimicrobial and antioxidant properties. Intragroup assessment of clinical trial showed significant reduction in the OHI-S [Group I (p=0.03), Group II (p=0.01)] plaque scores [Group I (p=0.05), Group II (p=0.006)] and Streptococcus colony counts [Group I (p=0.000), Group II (p=0.000)] in both the groups. But there was no statistically significant difference between the two groups. Conclusion: The newer custom-made natural tooth powder is effective in oral hygiene maintenance and can be a possible alternative to the commercially available natural tooth powder.

Objective This study aimed to assess whether cord blood carboxyhemoglobin (COHb) levels in jaundiced term neonates with and without a positive direct Coombs test (DCT) and in healthy controls could be used as a predictor of severe hyperbilirubinemia. The percentage of cord blood COHb should be higher among neonates with Coombs-positive ABO hemolytic disease than among those with Coombs-negative ABO incompatibility and higher than that of ABO-compatible control neonates. Study Design This cross-sectional descriptive study of 198 term neonates comprised three subgroups: group I featured 68 DCT-positive ABO-incompatible neonates (ABO + DCT), group II featured 60 DCT-negative ABO-incompatible neonates with hyperbilirubinemia (ABO–DCT), and group III featured 70 healthy controls. COHb was determined by an OSM3 hemoximeter. Results Group I differed from groups II and III for cord blood bilirubin, cord blood hemoglobin, and cord blood hematocrit. Groups I and II had higher mean total serum bilirubin (TSB) levels than group III, while there was no difference in the mean TSB levels between groups I and II. There was no significant difference between the COHb group means for groups I, II, and III (p = 0.98). The area under the receiver operating characteristic curve calculated for group I/group III and group II/group III were found to be 0.62 and 0.54, respectively. Conclusion COHb levels did not prove to be superior to the DCT for predicting the risk of developing severe hyperbilirubinemia in term neonates. Key Points

The significant difference between recycled aggregate and natural aggregate is the content of the attached mortar layer. With the increase of the replacement rate of recycled aggregate, the shrinkage and creep of recycled aggregate concrete is significantly increased. In this paper, 180-day shrinkage and creep tests of recycled aggregate concrete with different water–cement ratios were designed in order to analyze the effect of the substitution rate and water–cement ratio on shrinkage and creep properties. The results show that the shrinkage strain of recycled aggregate concrete with a substitution rate of 50% and 100% at 180 days is 26% and 48% higher than that of ordinary concrete, respectively, and the growth of group II is 22% and 47%, respectively. When the load was 180 days old, the creep coefficient of recycled aggregate concrete with a substitution rate of 50% and 100% in group I increased by 19.6% and 39.6%, respectively compared with ordinary concrete, and group II increased by 23.6% and 44.3%, respectively. Based on the difference of adhering mortar content, the creeping increase coefficient and shrinkage increase coefficient of the attached mortar were proposed, and a shrinkage and creep model of recycled aggregate concrete was established. When compared with the experimental results, the model calculation results met the accuracy requirements.

Objective: To evaluate the efficacy of immersive VR (IVR) and non-immersive VR (NIVR) distraction on perceived pain during intraoral injections in children undergoing dental procedures. The objective was to introduce 3-dimensional nature of virtual reality during the provoking phase of dental treatment as a means of distraction in children. Study design: A total of 200 children were selected for the study, 100 for IVR group and 100 for NIVR group. After randomization, children were introduced to Oculus Go Standalone equipment; MCDAS (f), VAS, WBFRS and the treatment procedure using tell show do technique. Group I children were introduced to oculus go standalone headset with hand held controller to play temple run or roller coaster game while in group II, children watched cartoon movies of their choice. Pre-operative & post-operative MCDAS scores were obtained using MCDAS (f) questionnaire in local language. Post-operatively, VAS and WBFRS scores were also obtained. The data was analyzed using independent t-test and chi-square analysis. Results: Pre-operatively, the mean MCDAS scores were similar in both the groups viz. Group–I (29.20 ± 3.197) and Group–II (29.09 ± 3.803) and is statistically not significant. Post-operatively, the mean MCDAS scores were higher in non-immersive group (20.72 ± 2.822) as compared to immersive group (10.99 ± 2.227). VAS score was higher in non-immersive group (2.72 ± 0.99) as compared to immersive group (0.75 ± 0.88). WBFRS scores were higher in non-immersive group (2.78 ± 1.097) as compared to immersive group (0.82 ± 1.104). Conclusion: Three-dimensional virtual reality was found to be an effective means of distraction in children undergoing dental procedures and especially during the provoking phase. The significant difference obtained clearly indicates irrespective of immersiveness of virtual reality, anxiety had been decreased and on comparison the pain perception to intraoral injection is less in immersive virtual reality environment. Immersive VR distraction technique can serve as an adjunct to traditional behavior management strategies already available to the pediatric dentist.
