RESUMEN

OBJECTIVE: To evaluate the association between body mass index (BMI) and oral health status among elementary school children in Hyderabad, Telangana, India. MATERIALS AND METHODS: This cross-sectional study was conducted among elementary school children selected from government, private-aided and private-unaided schools in Hyderabad. A stratified cluster random sampling technique was used to select study participants. All parents were requested to be personally present on the day of examination. All eligible children were assembled in a hall and their height in inches and weight in kilograms were recorded by two calibrated investigators. The oral health status of children was assessed using a predesigned oral health assessment proforma. Plaque status was assessed using Sillness and Loe plaque Index and caries using decayed and filled teeth (dft) by a trained and calibrated investigator. RESULTS: One hundred and seventy-one children (89 males and 82 females) were included in the present study. Mean plaque score was 1.4 ± 0.6 with no significant difference in the mean plaque score between children in three different categories of nutritional status (P = 0.07). Mean dft among primary teeth was 1.1 ± 1.1 with a significantly higher score among children who were malnourished (2.4 ± 0.9) compared to children who were overweight (0.9 ± 0.9) and normal (0.4 ± 0.6) (P < 0.001). CONCLUSION: BMI was negatively associated with caries experience in primary dentition with no association with plaque scores. Overweight children with malnutrition had significantly higher caries experience compared to children with normal BMI.

RESUMEN

BACKGROUND: Tobacco use has become an epidemic of modern times. Its use is widespread among young adults and those from lower socioeconomic classes. OBJECTIVE: The objective is to assess knowledge, attitude, and practices (KAP) and motivation to quit tobacco habits in relation to age and educational status among male tobacco users visiting a Government Dental College Hospital, India. MATERIALS AND METHODS: This was a questionnaire survey conducted among 199 male adult smokers visiting the Department of Public Health Dentistry in a Government Dental College in India. Quota sampling was used for recruiting the required number of study participants. Information on KAP related to smoking habits was collected using a predesigned structured questionnaire by two trained and calibrated dentists. Knowledge, attitude toward quitting and their self-confidence toward quitting was compared in relation to age and educational status using Chi-square test. RESULTS: A higher percentage of younger adults aged 18-24 years were interested in quitting the habit (100%) compared to those aged 45-64 years (85.2%). Similarly, a higher percentage of young adults have tried quitting the habit (76.9%) compared to their older counterparts (64.8%) (P < 0.05). Knowledge on ill effects of smoking increased with increasing educational attainment (P < 0.001). People with higher educational attainment had observed the warning sign on packaging (73.7%) compared to those with less than primary education (25.9%) and they also reported that the presence of such warning sign motivated them to think about quitting (54.8% vs. 0%) (P < 0.001). CONCLUSION: Knowledge, positive attitude toward quitting and self-confidence to quit were higher among younger adults and those with secondary education compared to their elder counterparts and those with less than primary education.

RESUMEN

Plant secondary metabolites are widely used in human disease treatment; though primary metabolism provides precursors for secondary metabolism, not much has been studied to unravel the link connecting both the processes. Most common form of gene regulation interconnecting diverse metabolism occurs at the transcriptional and/or posttranscriptional level mediated by regulatory cis-elements. The present study aims at understanding the common cis-elements network connecting the major primary metabolic enzyme, cell wall invertase (CWIN) and secondary metabolism genes in Nicotiana benthamiana (N. benthamiana). The CWIN and thirty one other gene sequences were extracted from N. benthamiana genome, followed by cis-element analysis of their 5' upstream and 3' downstream region using different programs (Genomatix software suite; PLACE and PlantCARe). Comparative cis-element analysis of CWIN (N. benthamiana and other plant species) and other primary, secondary metabolism and transcription factor genes (N. benthamiana) revealed the occurrence of common stress associated cis-elements. Predominantly, AHBP, L1BX, MYBL, MADS, MYBS, GTBX, DOFF and CCAF were found in the 5' upstream region of all genes, whereas AHBP, MYBL, L1BX, HEAT, CCAF and KAN1 were largely occurring in the 3' downstream region of all genes; indicating common function of these elements in transcriptional and posttranscriptional gene regulation. Further, genomic analysis using FGENESH, GenScan and homology based methods (BlastX and BlastN) was performed on the N. benthamiana contigs harboring CWIN and PAL, in an attempt to identify genomic neighborhood genes. The 5' upstream and 3' downstream region of genes in the genomic neighborhood of CWIN and PAL were also subjected to similar cis-element analysis, and the results indicated cis-elements profile similar to CWIN, PAL and other primary, secondary metabolism and transcription factor genes. The results of evolutionary studies confirmed that the 5' upstream region of NbCWINs significantly showed more proximity to secondary metabolism genes 4CL and the redox gene SOD, followed by the phenylpropanoid pathway gene CHI. The 3' downstream regions of NbCWINs were more closely related to other plant CWINs, followed by the redox gene, SOD and primary metabolism gene FBA. Thus, the commonly found stress responsive cis-elements in our study can play a vital role in modulating key pathways of both primary and secondary metabolism; thereby postulating their role in regulating plant growth and metabolisms under unfavourable growth conditions.

RESUMEN

OBJECTIVE: To compare the efficacy of three different herbal products (Tooth and Gums Tonic, Hiora-GA gel, and Spirogyl Gum paint) in reducing plaque, gingival inflammation and bacterial count in comparison with chlorhexidine M gel among participants with moderate to severe periodontitis. MATERIALS AND METHODS: A total of eighty participants with moderate to severe periodontitis were initially recruited after obtaining their informed consent. All participants were offered scaling and polishing on the first visit to remove visible calculus. Then, these participants were randomly divided into four groups of twenty participants each using block randomization method. Participants in Group 1, 2, 3, and 4 were given chlorhexidine M gel, Hiora-GA gel, Spirogyl Gum paint, and Tooth and Gums Tonic, respectively. All participants were instructed to brush their teeth twice day with a soft bristled toothbrush and their regular fluoridated toothpaste. They were instructed to apply the respective gels twice a day according to the manufacturer's guidelines. The posttreatment follow-up examinations for gingival and plaque changes were assessed after 30, 60, and 90 days by three trained and calibrated investigators using gingival and plaque index. The investigators and statistician were blind about group allocation. The supragingival plaque samples were collected before and 90 days after treatment from the buccal surfaces of maxillary right first permanent molar of each participant for microbial analysis. RESULTS: The mean plaque, gingival scores significantly decreased at different intervals following intervention in all groups. The bacterial counts also significantly reduced postintervention with no significant difference in the efficacy of these products compared to chlorhexidine. CONCLUSION: All three herbal products were found to be effective when used along with oral prophylaxis. Hence, they can all be used as alternates to chlorhexidine in the management of periodontal diseases.
