Semi-structured in-depth interviews were conducted with piercers and those who had their tongue pierced (“piercees”) in Klang Valley. Five piercers and eight piercees were interviewed. Piercees had their tongue pierced at age 16-25 years. Three mainreasons for tongue piercing were to enhance appearance, express their individuality, and out of curiosity. They reported that they experienced various immediate and late complications. However, most were aware of and expected the complications. The majority of piercers reported adequate infection control procedures and enquired about the client’s health prior to piercing. Although some clients reported problems, such reports were rare. Tongue piercing is an invasive procedure with some risks, but precautions such as proper infection control procedures minimize the likelihood of encountering serious problems. The reasons for tongue piercing varied between individuals. Although the majority of the interviewed piercers reported cross-infection control, their knowledge of the medical risks associated with tongue piercing varied widely.","PeriodicalId":75515,"journal":{"name":"Annals of dentistry","volume":"689 1","pages":"10-19"},"PeriodicalIF":0.0,"publicationDate":"2016-12-30","publicationTypes":"Journal Article","fieldsOfStudy":null,"isOpenAccess":false,"openAccessPdf":"","citationCount":null,"resultStr":null,"platform":"Semanticscholar","paperid":"68631782","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}

This cross-sectional study was carried out on pediatric dental patients with ECC attending a public university hospital. Theparents or guardians were interviewed for the bottle-feeding pattern and oral hygiene practices followed by a clinical dental examination of their children with ECC. Data analysis was done using Chi squared test. Out of 32 children, 69% had severe early childhood caries with mean dft of 8.88. In this study, 87.5% ofthe subjects had a history of bottle feeding, with 53.1% still being bottle fed at the time of study. Current bottle-feeding habit was found to be statistically significant with the severity of caries (p=0.021). Majority (69 %) of the children were introduced to tooth brushing only after 1 year of age. About 40% of the children consumed either pre-chewed rice and/or shared spoons or feeding utensils with their parents or siblings but there was no significant association with the severity of caries (p=1.00). Because of its association with ECC, prolonged bottle feeding is significantly associated with the severity of caries in our study population. Besides, vertical and horizontal transmission of bacteria was also a risk factor for ECC, but it did not show any significant association with severity of ECC.","PeriodicalId":75515,"journal":{"name":"Annals of dentistry","volume":"23 1","pages":"1-8"},"PeriodicalIF":0.0,"publicationDate":"2016-12-30","publicationTypes":"Journal Article","fieldsOfStudy":null,"isOpenAccess":false,"openAccessPdf":"","citationCount":null,"resultStr":null,"platform":"Semanticscholar","paperid":"68632252","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}

In addition, the depth of cure of the two bulk-fill resin composites was also investigated. The materials were prepared and tested for the mechanical properties following ISO 4049:2009. Microhardness and depth of cure were measured using Vickers hardness tester. Compressive and flexural strength were tested using a universal testing machine. To determine the depth of cure, microhardness of the bulk-fill composites were measured as a function of selected depth of materials at 0.5 mm, 2.0 mm and 4.0 mm. Data were analyzed by either one-way ANOVA or Friedman test. Analysis demonstrated that SonicFill™ gave the highest microhardness value (101.8 + 4.6 VHN) compared to the other two groups. There were no significant differences among all groups in flexural and compressive strength. The depth of cure decreased as the thickness of both bulk-fill composites increased. In conclusion, SonicFill™ showed favorable mechanical properties compared to other composites tested. In both bulk-filled groups, microhardness value decreased as the thickness of the composite increased. The polymerization of the bulk-filled composites was effective only at 2 mm or less.","PeriodicalId":75515,"journal":{"name":"Annals of dentistry","volume":"23 1","pages":"11-16"},"PeriodicalIF":0.0,"publicationDate":"2016-06-30","publicationTypes":"Journal Article","fieldsOfStudy":null,"isOpenAccess":false,"openAccessPdf":"","citationCount":null,"resultStr":null,"platform":"Semanticscholar","paperid":"68631889","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}

Cells propagated in 3D cell culture model, on the other hand, exhibit physiologically relevant cell-to-cell interactions and cell-to-extracellular matrix (ECM) interactions, important in maintaining a normal homeostasis and specificity of tissues. This review gives an overview on 2D models and their limitations, followed by 3D cell culture models, their advantages, drawbacks and challenges in present perspectives.

High Aesthetic Sentalloy (full rhodium coating nickel-titanium; Dentsply GAC) represented the initial aesthetic archwires; and FLI TRU-CHROME (labial PTFE-coated stainless steel; RMO) as the working aesthetic archwires; together with their conventional counterparts were analysed. A three point bending test was conducted using a universal testing machine (AGS-X SERIES, Shimadzu, Japan) to determine the load-deflection characteristics of archwires. Surface hardness was evaluated by Vickers microhardness test (HMV-FA, Shimadzu, Japan). A 3D Optical Surface Texture Analyzer (ALICONA, InfiniteFocus Real3D, Belgium) and a Field Emission Scanning Electron Microscope (FESEM, FEI Quanta 250, USA) were used for surface evaluation. Results showed that loaddeflection characteristics of High Aesthetic Sentalloy archwires did not differ from its control, whereas FLI TRU-CHROME archwires exhibited higher loading and unloading forces than its counterpart. No statistically significant difference in surface hardness was found between FLI TRU-CHROME and its control archwires. The coating surfaces of both aesthetic archwires were rougher than the non-coated conventional archwires, with similar roughness between non-coated surface of FLI TRU-CHROME archwires and its counterpart. FLI TRU-CHROME archwires showed a distinct coating thickness but coating layer is undefined in High Aesthetic Sentalloy archwires. In conclusion, the aesthetic rhodium coated nickel titanium archwire has similar mechanical properties as control nickel titanium archwire without being adversely affected by the addition of the coating layer. The aesthetic coated PTFE stainless steel archwire has higher load response which could be an advantage as rigid wire in working stage of orthodontic treatment. Based on their performance, their use could be recommended in cases where aesthetic aspect is crucial and where the friction aspect is not critical as their surface roughness values increased.","PeriodicalId":75515,"journal":{"name":"Annals of dentistry","volume":"23 1","pages":"17-28"},"PeriodicalIF":0.0,"publicationDate":"2016-06-30","publicationTypes":"Journal Article","fieldsOfStudy":null,"isOpenAccess":false,"openAccessPdf":"","citationCount":null,"resultStr":null,"platform":"Semanticscholar","paperid":"68631963","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}

Retrospective data on cases of diagnostic wax-ups, full metal crowns, metal ceramic crowns, all ceramic crowns and bridges that were sent to ceramic laboratory for fabrication from 1 st of September 2013 to 31 st of August 2014 was systematically extracted from the record and tabulated categorically in SPSS version 22.0. The turnaround time in workings day for diagnostic wax-ups and the prostheses was calculated by deducting exit date from entry date. Subsequently, the turnaround time and the complexity of cases were categorized accordingly. The association of turnaround time and the complexity of the cases was analysed using Fisher Exact test with p value < 0.05. Within this time frame, a total of 102 cases of diagnostic wax-ups, 36 cases of crown and 18 cases of bridges were fabricated. 57.8% of diagnostic wax-ups were completed within 3 days. 100% of 1 unit crown were completed within 7 days and 94.4% of bridges were completed within 14 days. There was a significant association of turnaround time and the complexity of the cases for diagnostic wax-ups and crowns with p value <0.05.
