Various drugs are used to accelerate wound healing in soft and bone tissues.In this study, the effect of 0.2 chlorhexidine gel and 10 betadine gel on tooth socket healing was investigated. Materials and Methods: This experimental study was performed on 45 male mice randomly divided into three groups of 15. Under general anesthesia, the right maxillary second molar of all of the mices were extracted. The socket of the first group was covered with 0.2 chlorhexidine gel and the second group was covered with 10 betadine gel, and the socket of third group was left empty. On the third, seventh and fourteenth days after surgery, one third of the animals were sacrificed from each group. Then the prepared slides from each group were examined. Results: The extent of granulation tissue on the third day after tooth extraction in the chlorhexidine group was greater than the remaining two groups.. The number of lymphocyte on the seventh day after tooth extraction in the chlorhexidine group were lower than the control group. The number of macrophage on the 14th day after tooth extraction in the chlorhexidine and betadine groups was lower than the control group. The number of fibroblasts in the chlorhexidine group on the 14th day after tooth extraction were higher than the control group. These differences were statistically significant. Conclusion: According to the results of this study, 0.2 chlorhexidine gel can accelerate the process of tooth socket healing.","PeriodicalId":90904,"journal":{"name":"Journal of oral hygiene & health","volume":"1 1","pages":""},"PeriodicalIF":0.0,"publicationDate":"2018-09-17","publicationTypes":"Journal Article","fieldsOfStudy":null,"isOpenAccess":false,"openAccessPdf":"","citationCount":null,"resultStr":null,"platform":"Semanticscholar","paperid":"70291130","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}

Their tooth-brushing motion for 15 seconds was captured using a motion-capture system. The buccal and palatal sides of the right and left upper molars using both the pen and palm grips were brushed, and the frequency of joint angles of the shoulder, elbow, and wrist was calculated during tooth-brushing.Results: Individuals showed smaller intra-individual variations in the peak frequency of the toothbrush and joint angles during the brushing of all sides with both the pen and palm grips. For some arm joints, using the palm grip showed higher intra-individual variations than inter-individual, but the intra-individual variations among all joints using the pen grip were lower in all brushing areas.Conclusion: A distinct individual tooth-brushing rhythm in the reciprocatory motion was established by each dental hygienist using both the pen and palm grips. The coordinated movements of all joints of subjects using pen grips reflected the stability of the tooth-brushing motion of each arm joint. However, when using the palm grip, it is not necessary to ensure joint stability during tooth-brushing motion. Examination by three-dimensional toothbrushing motion analysis revealed that the reciprocatory performance during tooth-brushing was easier with the palm grip than with the pen grip.","PeriodicalId":90904,"journal":{"name":"Journal of oral hygiene & health","volume":"6 1","pages":"1-6"},"PeriodicalIF":0.0,"publicationDate":"2018-05-23","publicationTypes":"Journal Article","fieldsOfStudy":null,"isOpenAccess":false,"openAccessPdf":"","citationCount":null,"resultStr":null,"platform":"Semanticscholar","paperid":"70291513","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}

Rubber dam is considered to be an essential tool for conservative dentistry; hence its preclinical training to dental students is of uttermost importance. Due to lack of previous study, this study aims to assess the experience of undergraduate dental students at Fiji National University (FNU) on use of rubber dam. \u0000Methodology: This is a cross-sectional quantitative study whereby 48 self-administrated questionnaires were distributed among the third, fourth and fifth year dental students at FNU. All the students in that respective year were also observed for the time taken to place rubber dam using an observation checklist. The data was analyzed using the Epi-Info software. \u0000Results: A 100% response rate was obtained. Among the 48 participants, 30 were females and 18 were males. 75% of the participants stated moisture control as the major advantage of rubber dam use. Difficulty in placing rubber dams was a main disadvantage highlighted by 35% of the student while 27% stated that placing rubber dam took up extra clinical time. The mean time taken to place rubber dam was 6 minutes to the nearest minute on adult patients. Students preferred to use cotton rolls for isolation during Glass Ionomer Cement (79%) and Amalgam (65%) procedures. Majority of the students felt that the training and teaching sessions on rubber dam are sufficient. The major problems identified by students while placing rubber dam were lack of appropriate clamps, patient acceptance and compliance. \u0000Conclusion: The level of knowledge among undergraduate students on the advantages and disadvantages of rubber dam is high. There are various factors in practice and training that could be emphasized to encourage students on future use of rubber dam. Among the undergraduate dental students there was still a high possibility that they might not practice routine placement of rubber dam after graduation. There is scope for further study on the rubber dam practice of general dental practitioners.","PeriodicalId":90904,"journal":{"name":"Journal of oral hygiene & health","volume":"6 1","pages":"1-5"},"PeriodicalIF":0.0,"publicationDate":"2018-04-21","publicationTypes":"Journal Article","fieldsOfStudy":null,"isOpenAccess":false,"openAccessPdf":"","citationCount":null,"resultStr":null,"platform":"Semanticscholar","paperid":"46063870","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}

Intermediate treatment options, similar to pit-and-fissure sealing on occlusal surfaces that has been shown to be effective in preventing and inhibiting caries, have not yet been established on interproximal surfaces. Recently, the application of resins on interproximal caries lesions has been studied and improved, leading to the development of new materials, which infiltrate and seal the carious lesion, improving the inhibition of caries progression. \u0000Aim: The aim of this literature review was to revise the in vivo and in vitro scientific evidence of the ability of resin infiltration (RI) to arrest non-cavitated proximal caries lesions. \u0000Materials and methods: Electronic search of English scientific papers from 2007 to 2017 was accomplished using Pub Med search engine. The keywords used were ‘resin infiltration, dental caries’, ‘resin infiltration, carious lesions’, ‘resin infiltration, caries lesions’, ‘caries infiltration’ and ‘Icon DMG’ with the ‘clinical trial’ filter activated. \u0000Results: One hundred and forty articles were reviewed as well as some references of selected articles.

Recent studies have revealed that GO exerts antibacterial properties, absorbs near-infrared (NIR) irradiation and generates heat. In this study, we fabricated a GO film on a human dentin block and investigated the photothermal and antibacterial effects of GO and NIR irradiation against Streptococcus mutans. \u0000Methods: The dentin block was immersed in GO dispersion (concentration: 0, 1 and 10 μg/mL). GO-coated dentin blocks were observed using scanning electron microscopy (SEM) and characterized using the dentinal tubule sealing score. The temperature increase of the GO-coated dentin surface following NIR irradiation was examined by thermography. Furthermore, antibacterial effects of the combination of GO film and NIR irradiation against S. mutans were evaluated by SEM observation, turbidity measurement, colony formation assessment and live/dead staining. \u0000Results: A thin GO film with a thickness of a few nanometers was successfully formed on the dentin surface. The dentinal tubule sealing score increased in a GO concentration-dependent manner. Even after ultrasonic cleaning, GO residue was frequently observed on the dentin surface. When the GO-coated dentin block was irradiated with NIR light, the temperature of the dentin block surface increased in a GO concentration- and time-dependent manner. In antibacterial assessments, turbidity and colony formation were suppressed by GO and NIR irradiation. In addition, dead bacteria were detected by live/dead staining. \u0000Conclusion: A stable GO film was successfully formed on the dentin surface by immersion in GO dispersion. Photothermal and antibacterial effects were remarkably exhibited by GO and NIR irradiation.","PeriodicalId":90904,"journal":{"name":"Journal of oral hygiene & health","volume":"6 1","pages":"1-6"},"PeriodicalIF":0.0,"publicationDate":"2018-01-10","publicationTypes":"Journal Article","fieldsOfStudy":null,"isOpenAccess":false,"openAccessPdf":"https://sci-hub-pdf.com/10.4172/2332-0702.1000231","citationCount":null,"resultStr":null,"platform":"Semanticscholar","paperid":"47316114","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}
