This is especially helpful for infants and toddlers. Aim: The aim of this study was to evaluate and compare the effect of three different fluoride varnishes (Durashield, Flour Protector and Bifluoride 10) on streptococcus mutans and lactobacillus count (in vitro study). Materials and methods : Total of 144 acrylic discs were divided into two main equal groups of 72 discs in each (group A: for examination of Streptococcus mutans and group B: for examination of Lactobacillus ); each group was further subdivided into four equal subgroups based on the type of varnish applied to the disc surface (A1, B1: Durashield; A2, B2: Fl protector; A3, B3: Biflouride; A4, B4: untreated discs served as control). Saliva collected from single volunteer was poured into tubes until the discs were completely immersed and incubated for 24h, 48h and 5 days. Six discs from each subgroup were taken out from tubes every time and sonicated in saline. Suspensions were been plated on selective media for Streptococcus mutans and Lactobacillus . The numbers of colony-forming units (CFU/mL) on suitably diluted plates were been determined. Results : For all tested subgroups, the lowest amount bacterial count of Streptococcus mutans and Lactobacillus was observed during the first 24 h, followed by a significant increase over the following 4 days. Biflouride subgroups had the lowest values of viable Streptocoocusmutans and Lactobacillus counts during all test periods. In comparison Durashield with Flour protector subgroup difference of viable counts of streptocoocusmutans and lactobacillus was observed but statistically non-significant. Conclusions : Biflouridevarnish exhibited the greatest antibacterial effect ( Streptococcus mutans and Lactobacillus ) compared to Durashield and flour protector. Fluor protector varnish showed the same inhibitory effect of Durashildvarnish despite Flour protector had lower fluoride concentration than Durashield.","PeriodicalId":11270,"journal":{"name":"Dental Science Updates","volume":"48 1","pages":""},"PeriodicalIF":0.0,"publicationDate":"2022-09-01","publicationTypes":"Journal Article","fieldsOfStudy":null,"isOpenAccess":false,"openAccessPdf":"","citationCount":null,"resultStr":null,"platform":"Semanticscholar","paperid":"73498956","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}

It is a safe technique since it only works on the mineralized tissues, leaving the surrounding tissues’ perfusion and innervation unaffected. It reduces tissue thermal damage and prevents osteonecrosis. Aim: The aim of study was to evaluate the effect of using Piezosurgery on pain, swelling, and trismus after surgical extraction of impacted mandibular third molar. Patients and methods: This study was conducted on healthy patients classified as ASA class I patients. Fifteen patients with bilateral, symmetrical, mandibular impacted third molars that needed surgical extraction were selected and divided randomly into two equal groups 15 teeth for each group. The same patient is considered as control and study group. Group A: Underwent surgical extraction of impacted mandibular third molar with a conventional rotary device. Group B: Underwent surgical extraction of impacted mandibular third molar with piezoelectric device. Pain, edema, and trismus were evaluated after 2 and 7 days postoperatively, and the total number of analgesic tablets taken by the patient till day 7 was counted. Results: The results showed there was significantly less pain, edema, and trismus with piezosurgery compared to rotary instruments after 2 days and 7 days postoperatively. The total number of analgesics taken by the patients was significantly less with piezosurgery compared to conventional group.

In particular, self-adhesion to tooth structure in addition to its fluoride release that makes it suitable for treatment of majority of high caries risk cases. However, clinical usage of GIC is still limited due to their sensitivity to initial desiccation, low resistance to abrasion and low esthetic properties explaining why these materials are not widely used for permanent fillings. Materials and Methods: Class II occlusal slot cavities were prepared in the first permanent molar of sixty patients and restored randomly by two restorations, either; EQUIA ® Forte Fil (Glass ionomer with glass hybrid technology) or Zirconomer ® Improved (Zirconia-reinforced glass ionomer). Restorations were evaluated according to FDI criteria in terms of biological properties at baseline, after six months and one year. Results: Chi-square and Mann-Whitney tests revealed that there was no statistically significant difference between both materials with 100% success in all restorations in both groups at the base line. At six months follow up time, 92% of the EQUIA ® Forte Fil group and 68% of the Zirconomer ® Improved group were clinically successful. Meanwhile, at 12 months follow up time, 88% of the EQUIA ® Forte Fil group and 48% of the Zirconomer ® Improved group were clinically successful with significant difference between them at both six and 12 months.

Each group was subdivided according to diode laser application into 3 subgroups, then samples were placed individually in a test tube containing artificial saliva. Fluoride release was measured by ion selective electrode for fluoride. Results: Clinpro XT had the highest amount of fluoride release followed by Enamel pro. Meanwhile, NSF didn`t release a significant amount of fluoride. There was a statistically significant difference in fluoride release when diode laser was irradiated at 5 Watt, after Enamel pro and Clinpro XT application. However, no significant effect for diode laser irradiation on NSF was found when used either before or after NSF treatment.

With the emergence of Cone-beam computed tomography (CBCT) studying the maxillary sinus became more accurate. Aim: to find out if there is a correlation between the maxillary sinus volume and facial pattern in adults using cone beam computed tomography. Methods: Cone-beam computed tomography (CBCT) scans of 36 adults were obtained. They were divided equally into three groups: Normal facial pattern, hyper-divergent facial pattern and hypo-divergent facial pattern. The volume of the maxillary sinus on both the right and left sides were measured in each group using OnDemand3D software program. Results: The results of this study were that there is no significance difference between the maxillary sinus volume in the different groups of facial pattern. There is no significance between the volume of the maxillary sinus on the right and left side. Conclusions: There is no correlation between the maxillary sinus volume and the vertical growth pattern. The right and left maxillary sinus are corresponding to each other in volume. INTRODUCTION Evaluation of the maxillary sinus during orthodontic diagnosis is crucial since it may affect the orthodontist’s treatment plan. Precautions should be taken so that the line of treatment chosen not encroach on the integrity of the maxillary sinus(1). Orthodontic treatment plan is affected by the size and position of the maxillary sinus. Likewise, the maxillary sinus may be affected by different malocclusions either dental or skeletal, anteroposterior or vertical in terms of size and position(2,3). With the emergence of cone beam computed tomography (CBCT) and its advantages in the world of radiography appreciated, orthodontists are using it more and more frequently. Studying the maxillary sinus becomes more accurate and with a 3D approach and the volume of the sinus could be evaluated(4). Several researches were made to pinpoint whether there is a relation between maxillary sinus volume and malocclusion. Some studies show that there was a correlation between the maxillary sinus volume and vertical malocclusion however there were other studies that contradicted that findings(5-8).
