RESUMEN

AIM: The present study aimed to assess the use of various local drug delivery systems in the management of chronic periodontitis. MATERIALS AND METHODS: A total of 60 patients aged around 30-55 years were included. The subjects who were enrolled under took a phase I therapy that included scaling and root planing (SRP). Patients who satisfied the conditions for selection to enter the trial were assigned randomly to three groups, with each group consisting of 20 participants as follows: group I: controlled-release drugs-chlorhexidine gel, group II: metronidazole gel, group III: tetracycline fibers. The plaque index (PI), gingival index (GI), and periodontal pocket depth (PPD) were recorded after 1st week as the baseline data and were recorded again after 15 days and 30 days post-baseline. RESULTS: The mean GI scores were 1.32 ± 0.10, 0.88 ± 0.16, and 0.76 ± 0.12, at baseline, 15 days, and 30 days, respectively, in group I. In group II, the mean GI score reduced to 1.09 ± 0.83 at 30 days from 1.48 ± 0.27 at baseline. Likewise, in group III the mean GI score reduced to 0.90 ± 0.62 at 30 days from 1.38 ± 0.06 at baseline. All the groups demonstrated a statistically significant difference at various intervals. The mean PI score decreased to 0.90 ± 0.78 at 15 days from 1.46 ± 0.22 at baseline in group III. A statistically significant difference at different intervals was seen in group III only. In all groups, the intergroup comparison of PPD was found to be statistically significant. CONCLUSION: This study demonstrated that although thorough SRP is an effective treatment method for elimination of chronic periodontal pockets, improved results can be obtained by adjunctive use of locally administered chlorhexidine gel, metronidazole gel, and tetracycline fibers. CLINICAL SIGNIFICANCE: The use of the adjunctive local drug delivery system along with mechanical cleansing in the treatment of periodontal pockets in chronic periodontitis is therapeutically beneficial.

RESUMEN

AIM: Aim of this study was to assess the efficiency of different treatment modalities for oral submucous fibrosis. MATERIALS AND METHODS: Sixty patients were included in the study, which was diagnosed as stage II oral submucous fibrosis (OSMF) based on habitual history and clinical findings. Three groups were made after randomization, i.e., group 1: capsule lycopene group, group 2: capsule lycopene and injection dexamethasone, group 3: injection dexamethasone and hyaluronidase group. Symptom severity was done by visual analog scale (VAS) scoring system viz burning sensation/pain in the patients; patient satisfaction was assessed. Vernier calipers were used to measure patients' maximum mouth opening at day 1, 1st month, 2nd month, 3rd month. RESULTS: Male and female had the mean age of 28.20 ± 4.26 and 39.34 ± 2.12 in group 1, in group 2 was 27.88 ± 7.12 and 40.92 ± 7.16, in group 3 was 28.90 ± 8.69 and 40.10 ± 6.22, respectively. There was no statistically significant difference between treatment modalities based on satisfaction. On 2nd month, maximum patients with no pain were more in group 3 followed by group 2, and this was statistically significant. At a 3rd month, the maximum reduction in pain was in group 3 followed by group 2 and group 1. Mouth opening was improved in the group 3 followed by groups 2 and 1, respectively. On 3rd month statistically significant difference was observed between the study groups. CONCLUSION: The present study concludes that the treatment with dexamethasone + hyaluronidase group showed better results in improvement in mouth opening in OSMF patients than lycopene, lycopene and dexamethasone groups. Improvement in mouth opening, reduced burning sensation in OSMF patients was also shown by lycopene. Hence lycopene can be considered as a good alternative for treatment for OSMF when dexamethasone is contraindicated due to different reasons. CLINICAL SIGNIFICANCE: Any oral cavity part can be affected by OSMF including the pharynx. It is a potentially malignant disorder. So early recognition and initiation of the effective regimen for the treatment in both early and advanced cases of OSMF are necessary.

RESUMEN

AIM: The study aims to assess the Mentha piperita leaf extract's effectiveness against oral pathogens. MATERIALS AND METHODS: The leaf extract of M. piperita was prepared using cold water method. The three microbial strains, i.e., Streptococcus mutans, Aggregatibacter actinomycetem-comitans, and Candida albicans were used as microbiological materials. Chlorhexidine 0.2% was used as positive control. The digital caliper was used to measure the zone of inhibition to know the antimicrobial activity at 24 and 48 hours. To compare the activity within and between the different microbial strains, one-way analysis of variance (ANOVA) was used. To analyze the data, Statistical Package for the Social Sciences (SPSS) software version of 21.0 was used. The p-value ≤0.05 was considered as statistically significant. RESULTS: Maximum inhibition zone was seen in both M. piperita extracts and 0.2% chlorhexidine with S. mutans at 24 and 48 hours, followed by A. actinomycetemcomitans, and C. albi-cans respectively. The statistical analysis ANOVA reveals the statistically significant association of M. piperita extracts with p-value <0.001. The comparison with 0.2% chlorhexidine at 24 hours showed a p-value of <0.04 and at 48 hours, it showed a p-value <0.001, which was statistically significant. CONCLUSION: The present study concluded that M. piperita showed antimicrobial activity against the oral microorganisms which are causing major less or more severe oral diseases and it can be administered as an alternative medicine for the conventional treatment. CLINICAL SIGNIFICANCE: The study results serve as a guide in selecting and providing information about the efficacy of M. piperita extracts to the dental professionals. The discovery of a potential herbal medication would be a great development in the field of antimicrobial therapies.

RESUMEN

BACKGROUND: Measures of in vivo calcium status are important in understanding the mineralization capacity as it is an essential mineral component of both teeth and bone; and also play a vital role in the lipid profile and hormonal balance. AIM: To evaluate the existence of any disturbances in calcium metabolism and absorption induced by smoking, by quantitatively assessing the variations in the salivary calcium level between smokers and non-smokers with periodontitis and relating to their periodontal status. MATERIALS AND METHODS: A total of 50 male patients were selected and categorized as Group I (smokers with chronic generalized periodontitis) and Group II (non-smoker/ non-tobacco users with chronic generalized periodontitis). Clinical parameters such as Calculus Index and Community Periodontal Index were assessed. Subsequently two ml of unstimulated whole saliva was collected and subjected to biochemical analysis for the estimation of salivary calcium which was carried out in the next 20 min. RESULTS: Salivary calcium levels were significantly higher in Group I (2.2700) compared to Group II (1.7260). Higher calculus index and CPI index score were also seen in Group I when compared to Group II. CONCLUSION: Elevated salivary calcium level among the Group I emphasize the decreased calcium absorption efficiency among the smokers. High salivary calcium content hardens plaque more rapidly, indirectly influencing the level of oral hygiene.
