Group A (n=10) received BOI implant and Group B (n= 10) received Crestal implants in maxillary & mandibular anterior region. Volumetric analysis was performed with the post-operative radiological examination using cone bean computed tomography (CBCT). Results: The mean volumetric bone loss between Triple Disc BOI & Crestal Implant was 46.91 & 115.55 mm 3 respectively.

The aim of this study was to evaluate the genotoxic and cytotoxic occupational risk of dental surgeons and technicians through the micronucleated cells (MNC) and nuclear abnormalities (NA) assay in oral mucosa. Methods: Case-control study. We have collected a buccal mucosa from dental surgeons, dental technicians and healthy individuals (matched by BMI, age and gender). The smears were fixed (ethanol 80%/48 h), stained (orange acridine) and analyzed (microscope, 100×). The frequency of MNC and NA (binucleated cells [BNC], lobulated nucleus [LN], condensed chromatins [CC], karyorrhexis [KR], pyknosis (PN) and karyolysis [KL] were counted in 2,000 cells per participant. Results: 90 samples were collected (26 surgeons, 19 technicians and 45 controls). Compared with controls, exception of PN, in surgeons was higher frequency and positive association of MNC and all NA (p<0.05). Technicians were higher frequency of MNC, BNC, CC, KR and CD (p<0.05). Conclusion: The dental surgeons and technicians have genotoxic and cytotoxic damage, demonstrated by MNC and NA, which are related to an increase risk of cancer, chronic degenerative diseases and premature aging. It is necessary to improve biosecurity actions and implement routine genotoxic risk detection methods. *Correspondence to: Olivia Torres Bugarín, Sistema Nacional de Investigadores II, Laboratorio de Evaluación de Genotóxicos, Programa Internacional de Medicina, Universidad Autónoma de Guadalajara, Av.

Aloe vera is one such product exhibiting multiple benefits and has gained considerable importance in clinical research. This clinical study focuses on Aloe vera and highlights its property when used as a medicament in the periodontal pocket. Aim: The aim of this study was Evaluation of local – delivery system containing 80% aloevera gel used as an adjunct to scaling and root planning in chronic periodontitis. Objective: To evaluate the efficacy of Aloevera in reduction of gingivitis and periodontits and to compare the antioxidant level before and after alovera application on test site. Material and method: Present study was conducted among 30 patients having periodontitis. Split mouth design was used. GI, SBI, CPI, LOA & PD were recorded at baseline, 15 days & at 1 month. Immediately after recording all the indices at baseline and prior to drug application, the entire patient underwent scaling and root planning with hand instrument. The aloe vera gel was injected into the pockets with a syringe with blunt needle around the selected teeth in the treatment test site. The control site received only scaling and root planning. Biomechanical analysis-GCF was collected from 15 CP patients before and after treatment. Total antioxidant status was determined using colorimetric method and commercial kits. Result & conclusion: In the present study there was a significant difference in antioxidant level in GCF between test site and control site. Test site showed significant increase in antioxidant level and significant improvement in clinical parameter 2 month after application of aloe vera along with scaling and root planning while on control site there was no significant change in antioxidant level. There was strong significant positive correlation of antioxidant with probing depth and attachment loss. *Correspondence to: Vijayta Sharva, Reader, Public Health Dentistry, Peoples Dental Academy, Bhopal, Madhya Pradesh, India, Tel: 9827563977; E-mail: vijaytasharva@gmail.com","PeriodicalId":10996,"journal":{"name":"Dental, Oral and Maxillofacial Research","volume":"1 1","pages":""},"PeriodicalIF":0.0,"publicationDate":"2019-01-01","publicationTypes":"Journal Article","fieldsOfStudy":null,"isOpenAccess":false,"openAccessPdf":"","citationCount":null,"resultStr":null,"platform":"Semanticscholar","paperid":"89702317","PeriodicalName":null,"FirstCategoryId":null,"ListUrlMain":null,"RegionNum":0,"RegionCategory":"","ArticlePicture":[],"TitleCN":null,"AbstractTextCN":null,"PMCID":"","EPubDate":null,"PubModel":null,"JCR":null,"JCRName":null,"Score":null,"Total":0}

Resonances of surface Plasmon in these nanoparticles lead to increase in synchrotron radiation emission as a function of the beam energy scattering and absorption in related frequency [99-201]. Synchrotron radiation emission as a function of the beam energy absorption and induced produced heat in nanoparticles has been considered as a side effect in plasmonic applications for a long time [202-316]. Recently, scientists find that thermoplasmonic characteristic can be used for various optothermal applications in cancer, nanoflows and photonic [317-386]. In optothermal human cancer cells, tissues and tumors treatment, the descendent laser light stimulate resonance of surface Plasmon of metallic nanoparticles and as a result of this process, the absorbed energy of descendent light converse to heat in nanoparticles [387-399]. The produced heat devastates tumor tissue adjacent to nanoparticles without any hurt to sound tissues [400-417]. Regarding the simplicity of ligands connection to Flerovium nanoparticles for targeting cancer cells, these nanoparticles are more appropriate to use in optothermal human cancer cells, tissues and tumors treatment [418-442]. In the current paper, thermoplasmonic characteristics of spherical, core-shell and rod Flerovium nanoparticles are investigated.
