The connective tissue stroma has an essential role in the preservation of epithelial tissues and minor alterations in the epithelium are followed by corresponding changes in the stroma, such as angiogenesis. Vascular endothelial growth factor (VEGF) is considered the first factor which maintains its position as the most critical driver of vascular formation and is required to initiate the formation of immature vessels, with this aim, present study was executed to evaluate VEGF expression in kertocystic odontogenic tumor, dentigerous cyst and radicular cyst (RC).</p><p><strong>Materials and methods: </strong>A retrospective study was carried out comprising a total of 31 cases; 13 cases of keratocystic odontogenic tumor (KCOT), nine cases of dentigerous cyst (DC) and nine cases of RC.

The most common foreign bodies of iatrogenic origin encountered are restorative materials, like amalgam, and root canal fillings. The aim of this study was to determine the prevalence of foreign bodies detected with panoramic radiography in the jawbones, as well as to evaluate the etiology and characteristics of these pathologies. Materials and Methods: From March 2012 to January 2014, 11,144 panoramic radiographs were taken and retrospectively reviewed. The number, characteristics, location of the foreign bodies, age, and gender of the patients were recorded. Results: Of the 11,144 patients reviewed, 62 of them have a foreign body with a frequency of 0.6%. The patients who had a foreign body were between 14 and 81 years old. Female patients showed more foreign bodies than male patients. Among the 62 patients, 63 filling materials, one stapler, and five shrapnel were detected. Only 8 patients had symptoms associated with foreign bodies and these foreign bodies excised surgically. Conclusion: If possible, these pathologies must be removed at the time of detection to prevent further complications; however, in asymptomatic cases, according to location and the characteristic of the foreign body, they can be kept under observation without performing any operations.","PeriodicalId":90526,"journal":{"name":"Indian journal of dentistry","volume":"6 1","pages":"185 - 189"},"PeriodicalIF":0.0,"publicationDate":"2015-10-01","publicationTypes":"Journal Article","fieldsOfStudy":null,"isOpenAccess":false,"openAccessPdf":"","citationCount":null,"resultStr":null,"platform":"Semanticscholar","paperid":"70347657","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}

Methods: Single rooted human mandibular premolars were decoronated, biomechanically prepared, and vertically sectioned along the midsagittal plane to obtain a standardized tooth substrate. Standardized suspension of E. faecalis and tooth substrate was incubated for 3 weeks to allow growth of biofilm. At the end of 3 weeks, the grouping was done according to the medicament used – Group I - LZ, Group II - nisin, Group III - calcium hydroxide, Group IV - negative treatment. Disk of the medicaments used were prepared and placed upon Petri dishes along with bacterial emulsion on Mueller-Hinton agar. The zones of inhibition were checked after 2 and 7 days. Statistical Analysis Used: The scores were statistically analyzed using Tukey honest significant difference test and one-way analysis of variance. Results: Zone of inhibition obtained with LZ was widest followed by nisin and calcium hydroxide after a period of 2 days (P < 0.001). The size of the zone of inhibition remain unchanged for LZ and nisin group after 7 days (P > 0.001) unlike calcium hydroxide group where the zone decreased (P < 0.001).
