RESUMO
INTRODUCTION: The consumption of smokeless tobacco (SLT) and related products has become an epidemic worldwide, especially among young people, as they come into direct contact with the tissues of the oral cavity. Therefore, the present cross-sectional study was conducted to compare the status of dentition and periodontal health of teeth associated with the unilateral SLT pouch keratosis with the unaffected contralateral side. MATERIALS AND METHODS: In this study, 96 SLT users from north Maharashtra, India, with unilateral SLT pouch keratosis were studied. Demographic data, past and present SLT use history, features of SLT pouch keratosis, modified community periodontal index, dentition status index, and loss of tooth attachment were recorded. Data were collected and subjected to statistical analysis using the unpaired t-test and chi-square test. RESULTS: The results of the present study showed a significant difference (p≤0.05) in gingival bleeding, pocket depth, and attachment loss in teeth associated with smokeless tobacco keratosis (STK) compared to teeth at the contralateral sides of the arch. The duration of tobacco use had a significant effect on the severity of loss of attachment at SLT pouch keratosis sides. There was a significant difference (p≤0.05) in the mean scores of the sound crown, carious crown, and coronal caries status between the SLT pouch keratosis side and the contralateral side. CONCLUSION: The results of the study revealed that significant gingival bleeding, gingival recession, and attachment loss in the teeth are associated with SLT pouch keratosis compared with the teeth on the contralateral side without the lesion.
RESUMO
Introduction The earth has experienced significant shifts in climate patterns over the past few years. The main aim of this investigation was to establish the association between the sociodemographic factors on the extent of knowledge, perspectives, and awareness of the urban population in Delhi and the phenomenon of climate change. Materials and methods This study was conducted on 1,200 individuals residing in Delhi, India, who were given a well-organized validated questionnaire to gather data. The relationship between different factors influencing awareness and climate change was evaluated using the chi-square test. Results The investigation's findings revealed that the younger generations exhibited heightened consciousness as a result of the impact of education and social media, both of which possess an exceedingly significant role in the dissemination of awareness. Additional elements that influenced the participants' awareness regarding climate change encompassed their educational attainment, profession, and financial resources, which were noticeably more advantageous for the upper and upper-middle social strata. A majority of the respondents, amounting to 65%, hailed from the middle class, with 61% of them holding degrees. The majority of the respondents were well-informed about climate change, with a predominant percentage falling within the age range of 21-40 years (77%) and over the age of 61 years (73%). Notably, 92% of the respondents belonging to the upper class exhibited awareness of climate change. About 52% of the respondents expressed a moderate level of concern towards climate change. Conclusions The analysis revealed that most individuals possessed knowledge regarding the impact of climate change on their way of life. Consequently, they acknowledged the significance of acquiring a more comprehensive understanding of climate change.
RESUMO
INTRODUCTION: Periapical infection of primary molars affects the development of permanent teeth (premolars). Therefore, the present study was conducted to test the null hypothesis in children aged 4-10 years with chronic apical periodontitis (CAP) of the primary molars. MATERIALS AND METHODS: A retrospective, cross-sectional study was conducted on 185 panoramic radiographs of healthy children aged 4-10 years with CAP in the primary molars. A total of 256 infected primary molars (144 teeth in females, 112 teeth in males) were analyzed, radiographically, and compared with 245 healthy primary molars on the contralateral side. Permanent successors were evaluated for follicular damage, maturation, morphology, and deviation in the eruption path. Primary molars were evaluated for root resorption. Sixteen permanent teeth on the affected side and five teeth on the control side were excluded due to abnormal development. Student's t-test and the chi-square test were used to analyze the data. RESULTS: The null hypothesis is rejected. There were significant differences in the developmental status of permanent successors on the affected side, compared to the normal side at four to seven years (p<0.05). There were no significant sex differences in the abnormalities of permanent successors on the affected side (p>0.05). As the root resorption of the primary molars increased, the follicular damage observed in the permanent successors also increased (p<0.05), which suggests that, as the infection of primary molars increases, more damage is caused to underlying permanent successors (premolars). CONCLUSION: Apical periodontitis of the primary molars retards the development of permanent successors (premolars), affects their shape, causes follicular damage, and alters the eruption path.
RESUMO
Background: Fluoride (F) is an effective anticaries agent and can be delivered through various mediums at different concentrations. The ability to increase the enamel resistance to acid by decreasing solubility through the incorporation of F into the enamel apatite structure is the primary function of these agents. The efficacy of topical F can be determined by measuring the amount of F incorporated in and on human enamel. Aim: To compare the F uptake into and onto the enamel surface of two different F varnishes at different temperatures. Materials and methods: In this study, 96 teeth were divided equally and randomly (n = 48) into two experimental groups (group I and group II). Each group was further divided into four equal subgroups (n = 12); depending on the temperature (25°, 37°, 50°, and 60°C) they were subjected to Fluor-Protector® 0.7% and Embrace® 5% F varnishes were allocated to experimental groups I and II, respectively, and every sample was individually treated with the assigned F varnish. After the varnish application, two specimens from each subgroup, the group I and group II (n = 16), were mounted for hard tissue microtome sectioning for scanning electron microscope (SEM) analysis. The remaining 80 teeth underwent potassium hydroxide (KOH) soluble and KOH-insoluble F estimation. Results: Group I and group II, both, showed maximum F uptake of 2817.07 ppm and 1626.8 ppm at 37°C temperature and the lowest of 1168.9 ppm and 1068.93 ppm at 50°C, respectively. The intergroup comparison was carried out using an unpaired t-test and the intragroup comparison was done using one-way analysis of variance (ANOVA) univariate analysis.Post hoc Tukey test was performed for pairwise comparison between different temperature groups. In group I (Fluor-Protector®), the difference in F uptake was statistically significant when the temperature was increased from 25° to 37° C (mean difference = -9.90, p = 0.016). In group II (Embrace®), a statistically significant difference in F uptake was observed when the temperature was increased from 25° to 50°C (mean difference = 10.00, p = 0.003) and 25° to 60°C (mean difference = 13.38, p = 0.001), respectively. Conclusion: Fluor-Protector® varnish proved to have better F uptake in comparison to Embrace® varnish on human enamel. Topical F varnishes were most effective at 37°C, which is close to the standard human body temperature. Thus, the application of warm F varnish ensures more uptake of F in and onto the enamel surface for greater protection against dental caries.
