ABSTRACT
Accurate diagnosis and proper treatment planning should be established before making any prosthetic rehabilitation to restore the good appearance of the tooth, a better smile, phonetics, and to achieve perfect occlusion/mastication. We wanted to evaluate the changes of surface treatment protocols on the tensile bonding strength between enamel and ceramic restorations (lithium disilicate).METHODSA total of 20 freshly extracted, non-carious teeth were stored in normal saline solution at 25°C until used. Clean enamel surfaces 2 mm X 2 mm were obtained from the extracted teeth by using wheel diamond bur. Each enamel side received one E-max sprue, so four sprues of different surface treatment protocols per tooth (G1 TS: Etching, bonding, and curing. CS: Etching, monobond, curing, overall light cure) (G2 TS: Bonding, curing, self-etch / self-adhesive resin cement, overall light cure. CS: Monobond etch and prime) (G3 TS: Etching, bonding without curing. CS: Etching, monobond, curing, overall light cure) (G4 TS: Etching, bonding, curing. CS: Etching, monobond, bonding, curing, light-cure resin cement, overall light cure). Tensile bonding strength was measured using the Instron testing machine. One-way ANOVA test was used to analyse the data.RESULTSThe highest mean was observed in Group 3 (124.34±43.47) followed by Group 1 (104.29±50.09), which is control group. In contrast, the lowest mean was observed in Group 2 (83.64 ± 53.56) and Group 4 (94.14±57.91). The results of ANOVA test have shown a significant difference between the surface treatment groups at 5% significance level.CONCLUSIONSHydrofluoric acid and primer/silane coupling agent create a porous surface on the ceramic that allow a good interaction with silane coupling agent.
ABSTRACT
The concept of dental implant is receiving more attention globally. Tooth implant is one of the most significantmethods, which replaces the tooth in the natural way. Considering the economic and social factors, selection ofappropriate treatment has now become difficult. Due to the use of different implant related materials, dentalimplant processes are found to be more cost-effective in comparison to the conventional methods. The study aimsto systematically review previously done literature work and to analyze the association of economic and clinicalimplications of tooth implant support prosthesis (TISP). The current study has adopted qualitative secondaryapproach for data collection and analysis. The findings of this study showed evidence that tooth-implantprostheses are one of the efficient treating methods and has often undergone through failures due to differenttreatment factors. The study concluded that together with cost-effectiveness, the efficiency of treatment methodsmust be taken into consideration in the clinical practices.
ABSTRACT
Alveolar bone loss has now been identified as a growing problem among various periodontal diseases. Severalrestoration methods are being adopted depending upon the type of periodontal diseases. The present study aimedto investigate different causes and effects of alveolar bone loss along with the impact of restoration types onalveolar bone loss. A systematic review approach is followed to propose results for the intended objectives. Atotal of 14 studies were selected based on the inclusion and exclusion criteria for systematic review analysis thatfalls in the duration between Jan 2000 to Jan 2019. Ovid database, EMBASE, and Web of Science were used tosearch the given studies. Keywords such as; prostheses or restoration, loss of alveolar bone and types ofrestoration, orthodontic tooth movement or alveolar ridge preservation were selected. The articles providinginformation about the preservation of alveolar bone in clinical context, periodontal health conditions, and bonedensity around implants were included in the review; whereas, the articles with abstracts only and the remodelingprocess of implants were excluded. The risk of biasness was analyzed through Cochrane Collaboration’s tool.Reasons such as overhang fillings, impact of statins, subgingival calculus, oxidative stress, etc. were identified.Besides, the given studies are significant in indicating the effectiveness of different restoration types. The studyconcluded that there is a need to provide clinical trials regarding the impact of restoration types and causes ofalveolar bone loss.
ABSTRACT
Objective: In the healthcare setting, periodontal disease is among common dental disease resulting in tooth loss. Given its increasedprevalence, the study determines the correlation between oral hygiene and periodontal conditions using radiographic data. Methods: Across-sectional study design was used and radio-graphic data of 1000 patients (aged 16 years or above) from King Abdul Aziz UniversityFaculty of Dentistry (KAUFD) was assessed. The patients were divided into four groups based on their type of restoration; such asamalgam (77), composite (65), a crown (44), and temporary (11). Data was collected through questionnaire-based approach, which wasanalyzed statistically using SPSS. Results: Majority of the patients had fair oral hygiene (53.8%). The correlation analysis of oral hygienewith the restoration surface (p-value 0.571) and control tooth surface (p-value 0.476) was insignificant. Similar results were obtained forcase tooth (crown restoration) (p-value, .356) and control tooth (p-value, .925). However, there was significant effect of oral hygiene onrestored tooth bone loss (p-value, 0.004) and control tooth bone loss (p-value, 0.003). Conclusion: The study presents instigating initiativesto reinforce oral hygiene and educate general masses about periodontal conditions and its prevention
