Prime components of fixed orthodontic treatments decrease the self-cleansing ability of the tongue and the cheeks leading to an increase in production of bacterial plaque. Hence, the present study was undertaken for assessing the effect of fixed orthodontic treatment on gingival health.

A total of 120 patients who were scheduled orthodontic treatment were enrolled. Complete data records of all the patients were recorded. Intra- and extraoral radiographs were obtained and photographic records were noted in separate pro forma. Complete intraoral examination of all the patients was carried out for recording visible plaque, any inflammation (visible clinically), and gingival recession. Based on the assessment of gingival texture and capillary transparency, analysis of gingival biotype was done. Follow-up records were assessed.

The mean visible plaque value before treatment and after treatment was found to be 3.11 and 5.81, respectively. The mean visible inflammation value before treatment and after treatment was found to be 2.89 and 15.43, respectively. The mean gingival recession score value before treatment and after treatment was found to be 0.19 and 0.383, respectively. A significant increase in the visible plaque value, visible inflammation value, and gingival recession score was observed posttreatment. While comparing the gingival biotype, it was seen that in both the maxillary and mandibular arches, there was an increase in the thick gingival biotype while there was a decrease in thin maxillary biotype.

There is a significant increase in plaque accumulation, inflammation, and gingival recession following fixed orthodontic treatment. Hence, during the course of orthodontic treatment, regular oral prophylaxis should be done.

Tobacco usage can be equated to an unending progressive pandemic which continues to spread globally at an alarming unhindered pace. Dental surgeons have a key role in initiating reduction and even cessation of tobacco habits. Hence, the present study was undertaken for analyzing the habits of tobacco use among dental and nondental students of Indian population.

A total of 500 dental students and 500 nondental students were enrolled in the present study. Among dental students, only interns were enrolled across different dental colleges of India. A questionnaire was framed and was sent to all the students in the form of Google Forms. The questionnaire contained questions pertaining to the assessment of prevalence of tobacco use and type of tobacco use habit. All the results were recorded and analyzed.

Five hundred dental students and 500 nondental students were enrolled. Among the dental group, tobacco use habits were present in 23.8% of the students, whereas in the nondental group, tobacco use habits were present in 43.6% of the students. While comparing the prevalence of tobacco use habits among the dental and nondental groups, significant results were obtained. In the dental group, smoking habit and chewing habit were present in 44.54% and 32.77% of the students, respectively. In the nondental group, smoking habit and chewing habit were present in 52.29% and 29.82% of the students, respectively. While comparing the pattern of tobacco use among students of the two study groups, nonsignificant results were obtained.

There is an urgent need of tobacco cessation programs in the community to decrease the morbidity and mortality associated with it.

The present study was undertaken for evaluating various hand instrumentation techniques with different instruments in the formation of smear layer.

One hundred and seventy-five extracted mandibular molars were collected and were cut at cementoenamel junction. Afterward, the distal roots were separated. Working length was determined, and roots were divided into five equal groups with 35 roots in each group as follows Group A K-type files with conventional step-back technique, Group B Canal Master U instrument with clockwise-counterclockwise rotation, Group C Flex-R
files with clockwise-counterclockwise rotation, Group D FlexoFiles
with conventional step-back technique, and Group E Nickel titanium files with conventional step-back technique. Biomechanical preparation was done according to their respective groups. Saracatinib manufacturer The teeth in various groups were scanned under scanning electron microscope and scoring was done. All the results were analyzed by SPSS software version 17.0.

Scanning electron microscopic results indicated that apparently there seems to be a significant difference in the scoring of the smear layer between each group at all the three levels, but the difference was statistically nonsignificant. Microleakage was present in all the samples. Nonsignificant results were obtained while comparing the microleakage in between different the groups. However, microleakage was highest in Group D.

The amount of smear layer is maximum at the apical third and lesser in the middle third followed by the coronal third in all the groups. All the samples showed microleakage to a varying extent.

Bacteria and their by-products are responsible for various pulpal and periapical infections which can be classified as biofilm-mediated infections. Recently, nanoparticles have been introduced to decrease the bacterial load in endodontic infections.

The aim of the study was to compare and evaluate the antibacterial effect of silver nanoparticles alone and combination of silver nanoparticles with calcium hydroxide and chlorhexidine against
.

A pure culture of
was used as the test microorganism. After 24 h of incubation the bacterial colonies were isolated and suspended in 5 ml of infusion broth followed by incubation at 37°C for 4 h. 0.5 McFarland of the bacterial suspension was prepared and then cultured on Mueller-Hinton agar culture medium with the help of a sterile swab. In each culture plate, five wells were created with a sterile pipette for placement of the samples.

Statistically significant difference in the antibacterial effect of the combination of silver nanocure gel with various medicaments was observed when compared to the effect of silver nanocure gel alone. Silver nanocure gel in combination with calcium hydroxide (Group B) was more efficacious as compared to silver nanocure gel alone (Group A) (
< 0.001). Antibacterial activity of silver nanocure gel in combination with chlorhexidine (Group C) was also significantly higher than silver nanocure gel alone (
< 0.001).

The present study is an
study, in which we concluded that the combination of all the intracanal medicaments is the best among for elimination of
biofilm from the root canal. The above findings need to be tested
also.

This ex vivo study was designed to evaluate and compare different endodontic irrigation and activation systems, the self-adjusting file (SAF) instrumentation/irrigation system, and XP-endo finisher for removal of intracanal smear layer.

Fifty recently extracted, noncarious human intact single-rooted premolars were selected and divided into five groups (
= 10) according to the root canal irrigation systems; syringe and needle irrigation, passive ultrasonic irrigation (PUI), EndoVac irrigation system, SAF system, and XP-endo finisher. All groups were prepared to apical size F4 file except for the SAF group which was prepared to apical size 20 K-file and then instrumented with the SAF file. Each sample was subjected to final irrigation using different irrigation/activation systems. After splitting the samples, one half of each root was selected for examination under scanning electron microscope. The irrigation systems were compared using the Fisher's exact test with significance set at
< 0.05.

In the coronal part, there was no difference among the groups. In the mid-root section, the results of the PUI, EndoVac, SAF, and XP-endo finisher groups tended to be better than syringe and needle irrigation, but the difference was not significant. The apical part of the canal, the SAF system, and XP-endo finisher group seemed to be cleaner than those of the EndoVac group, but this difference was not significant.

Within the limitations of the present study, SAF system and XP-endo finisher group cleaned the apical part of the canal more efficiently than EndoVac, PUI, and syringe and needle irrigation.

The present study was conducted to assess risk factors and prevalence of potentially malignant disorders (PMDs) among Indian population.

1280 Indian population of both genders were enrolled. Habits such as smoking bidi, cigarette, consumption of tobacco such as in the form of zarda, chaini khaini, pan masala, arecanut, and alcohol were recorded. Risk factors and prevalence rate of disorders were recorded.

There were 750 (58.6%) males and 530 (41.4%) females. Speckled leukoplakia was seen among 470 (36.7%), oral lichen planus (OLP) in 246 (19.2%), oral submucous fibrosis (OSMF) in 274 (21.4%), erythroplakia in 120 (9.3%), and oral squamous cell carcinoma (OSCC) in 107 (8.3%) participants. Maximum cases of speckled leukoplakia (162) was seen in the age group of 31-40 years, OLP (99) in 41-50 years, OSMF (95) in 31-40 years, erythroplakia (48) in 21-30 years, OSCC (44) in 41-50 years.

Risks factors associated with PMDs were found to be tobacco and arecanut. There was higher prevalence of leukoplakia. Age group of 31-40 years had higher cases and most common site was buccal mucosa and vestibule.
