{"title":"Shear Bond Strength and Failure Mode of Different Dental Adhesive Systems","authors":"N. A. Yahya, Azizah Murtuzah Shekh","doi":"10.22452/ADUM.VOL26NO1","DOIUrl":"https://doi.org/10.22452/ADUM.VOL26NO1","url":null,"abstract":"The study aimed to evaluate the shear bond strength (SBS) and to analyse the failure mode at the resin-dentine interface of different dental adhesive systems. A total of 75 sound premolar teeth were selected and randomly assigned into five different adhesive groups (n=15): OptiBond Solo (OBS, total-etch), OptiBond Versa (OBV, two-bottles, self-etch), Adhe SE Ivoclar (ADHE, two-bottles, self-etch), G-Bond (GB, one-bottle, self-etch), and OptiBond All in One (OBO, one-bottle, self-etch). The occlusal surface of each tooth was flattened and composite resin cylinder (4x2 mm) was built up on the flat dentine surface using a custom made mould. The specimens were then subjected to 500 thermal cycles between 5 °C and 55 °C and dwell time of 20s. The SBS test was conducted using a universal testing machine at a crosshead speed of 0.5 mm/min. Data were analyzed using one-way ANOVA and Dunnett T3 Test. Failure mode was determined as adhesive, cohesive or mixed mode using a stereomicroscope and the data were analyzed using Fisher's exact test. The total-etch (OBS) had significantly higher value of SBS than the two self-etch (ADHE and GB) adhesive systems. Within the self-etch systems, OBV showed significantly higher SBS value compared to ADHE and GB. There were no statistically significant differences between types of failure mode (p > 0.05) and adhesive group. It can be concluded that the different compositions in the self-etch adhesive materials may contribute to the different SBS value. The failure modes detected within all tested groups did not show clinically important differences.","PeriodicalId":75515,"journal":{"name":"Annals of dentistry","volume":" ","pages":""},"PeriodicalIF":0.0,"publicationDate":"2019-04-04","publicationTypes":"Journal Article","fieldsOfStudy":null,"isOpenAccess":false,"openAccessPdf":"","citationCount":null,"resultStr":null,"platform":"Semanticscholar","paperid":"47141798","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}

Increasing demands of patients for aesthetics has resulted in the development of several techniques for restoring the anterior teeth. Composite resin restorations have become an integral part of contemporary restorative dentistry and can be called “star of minimal invasion” due to its conservative concepts. The direct composite veneering allows restoring the tooth in a natural way and preservation of sound tooth structure when compared to indirect restorations. Before placement of direct composite veneers, a proper diagnosis, available treatment options, cost of treatment, patient’s expectations and duration of treatment should be taken into consideration. This article presents three case reports of aesthetic rehabilitation of anterior teeth using direct composite with satisfactory outcome that mimic the natural dentition.","PeriodicalId":75515,"journal":{"name":"Annals of dentistry","volume":" ","pages":""},"PeriodicalIF":0.0,"publicationDate":"2018-12-31","publicationTypes":"Journal Article","fieldsOfStudy":null,"isOpenAccess":false,"openAccessPdf":"","citationCount":null,"resultStr":null,"platform":"Semanticscholar","paperid":"48199661","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}

All children below the age of 16 who have been clinically diagnosed with ASD and registered at the Pediatric Dental Clinic were included. The sample consisted of twenty children with ASD. Most of the sample were male and between 5-8 years old. Majority had good oral health behaviors but some exhibited self-injurious behaviors that may affect oral health. Severe characteristics of ASD, co-morbid conditions and incompetent health professionals were reported as barriers in oral care by parents of these children. Despite having good oral health behaviors, several barriers and challenges were expressed by these parents with ASD when providing home oral care or bringing them for dental appointment. Continuous support for parents with ASD child by dental professionals is essential to help overcome the real challenges and barriers in providing oral care among these parents.","PeriodicalId":75515,"journal":{"name":"Annals of dentistry","volume":"1 1","pages":""},"PeriodicalIF":0.0,"publicationDate":"2018-12-31","publicationTypes":"Journal Article","fieldsOfStudy":null,"isOpenAccess":false,"openAccessPdf":"","citationCount":null,"resultStr":null,"platform":"Semanticscholar","paperid":"68632048","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 would help dental clinicians to choose the best material of choice in the market. The authors have summarized the history, development and classification of different types of acrylic resins used in fabricating dentures and processing methods based on published research available on this topic using published materials available in the Dental Library, University of Malaya and the database (Science Direct, PubMed). Every type of acrylic denture base material has its pros and cons. Therefore, careful selection of the material and processing method is crucial to ensure patients are receiving the best outcome in prosthodontic treatment hence upholding the patients’ best interest and improving their quality of life.","PeriodicalId":75515,"journal":{"name":"Annals of dentistry","volume":" ","pages":""},"PeriodicalIF":0.0,"publicationDate":"2018-12-31","publicationTypes":"Journal Article","fieldsOfStudy":null,"isOpenAccess":false,"openAccessPdf":"","citationCount":null,"resultStr":null,"platform":"Semanticscholar","paperid":"47027686","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}

The study was carried out on patients diagnosed with classical trigeminal neuralgia at the Faculty of Dentistry, University of Malaya. Medical records of patients diagnosed with trigeminal neuralgia over a period of 11 years from April, 2003 to April, 2014 were reviewed. A total of 49 patients who fulfilled the inclusion criteria were included in the study. Demographic details, clinical features and blood test reports of the patients were recorded from the patient’s clinical files. Subjects included in the study were administered the Faces Pain Rating Scale (FPS) and Numeric Pain Rating scale (NRS) to measure the pain outcome retrospectively. Analysis and interpretation of results was carried out using SPSS. Hepatic adverse effects were more commonly seen in our patients (n=39) followed by haematological (n=27), renal (n=23) and non-specific adverse effects (n=22). However, there was no significant association between the observed side effects and carbamazepine pharmacotherapy. Analysis of our data using Pearson Chi Square test, showed no significant correlation between gender, ethnicity and age of the patients with adverse effects. 9 out of the 49 subjects included in the study were administered the FOS and the NRS. Pain perception after treatment was significantly decreased (p-0.007) in comparison to pain perception before commencement of therapy with carbamazepine in the selected group of patients. Even though pain perception decreased in the selected patients, the data is insufficient to state the efficacy of the treatment as none of the patients reported a complete relief from their pain. The results of our study showed that there were no significant haematological, hepatic, renal, and non-specific adverse effects associated with the use of carbamazepine. The efficacy of this drug in the treatment of trigeminal neuralgia was proven to be satisfactory. It may be concluded that carbamazepine could be considered as the drug of choice in the treatment of trigeminal neuralgia.","PeriodicalId":75515,"journal":{"name":"Annals of dentistry","volume":"23 1","pages":"20-27"},"PeriodicalIF":0.0,"publicationDate":"2016-12-30","publicationTypes":"Journal Article","fieldsOfStudy":null,"isOpenAccess":false,"openAccessPdf":"","citationCount":null,"resultStr":null,"platform":"Semanticscholar","paperid":"68631803","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}
