Eligibility criteria The eligibility criteria can be divided into inclusion and exclusion criteria. Inclusion criteria Participants should be within the age of 18-55 years at the commencement of the trial. Have BPE sextant codes less than 3 (i.e. code 0, 1, or 2) in permanent teeth (The British Society of Periodontology, 2011) (refer Appendix 1). Have at least one permanent tooth with a NCCL. Have a minimum of 20 natural teeth (these can include crowns and bridges on permanent teeth). The participant should have good oral hygiene and low caries index (DT<3). Were generally fit and well, with no systemic conditions or medication that could predispose to periodontal disease. Exclusion Criteria: Any patients with lesions involving …show more content…
Then, the teeth will be isolated with rubber dam (Hygienic Dental Dam, 2010). High and low volume saliva ejectors will be used additionally for suction of saliva and water from high speed hand piece. During preparation beveling of the enamel margins will be carried out for both groups to increase the surface area of enamel. The same set of burs and instruments will be used for preparation in both groups. Further, for the intervention group the enamel will be selectively etched for 15 seconds with 37% phosphoric acid followed by rinsing and drying of tooth. The one- step adhesive will then be applied to both enamel and dentin (Brady, 2013) with a micro tip applicator. Whereas, for the control group only the 1- step adhesive will be applied onto the prepared cavity. Furthermore, the adhesive will be cured with Mini LED light by Dentsply which has an intensity of 1250 mW/cm² (Adec, 2016). After curing of the bond, composite layering will be carried out by an incremental (0.5mm) placement of composite resin and cured with the same curing light to eliminate bias between the curing efficiency of different lights (Esmaeili, Safarcherati and Vaezi, 2014). Same set of instruments will be used for freehand shaping of composite between groups. A cellulose plastic matrix band and a wedge is used to contour the restoration interproximally (Chandra, S., Chandra, S. and Chandra, G. 2007). A microfilled composite resin [Filtek™ Z250 (3M ESPE)] …show more content…
Marginal integrity has been chosen as the primary outcome measure. Defects and/or gaps at the restoration margins signify poor marginal integrity. The outcome will be measured by modified USPHS (US Public Health Service Guidelines) criteria for direct clinical evaluation [Table 1]. By this the marginal integrity will be scored as Alpha (A), Bravo (B) or Charlie (C) depending on the clinical outcome at baseline followed by every six months for a period of 5 years. The scoring can be done by visual examination along with running an explorer along restoration

The IRB is an administrative body which has been established to make sure research participants' rights are protected. IRBs review all aspects of the researchers' project: the study design, the recruitment process, the participant population, the informed consent document and process, the risk/benefit ratio, privacy and confidentiality, data storage and protection, and safeguards for vulnerable participants (University of St. Francis, n.d.). In this way, participants' rights are protected because the effort is made even before the research begins. The review process ensures that participants are chosen fairly and informed adequately and the information collected during research is safeguarded through collection, use, and storage. Research using human participants is such an important part of medicine that it is imperative it is performed in a way that its intrigue is not compromised.
A good dental hygiene is very important for everybody no matter the age. A clean mouth will help us to stay more immune to infection and other risks that periodontitis can cause. Remember to take the time to brush and floss your teeth properly every day to keep your teeth and gums healthy. It is never too early or too late to begin taking care of your
Stoll, Betke et al. (2005) In a retrospective study estimated that the survival according their apical extent. Flush fillings had a 94% survival estimation while short and long fillings estimated results were 80.9% and 74.0% respectively in 5 to 10 years.(Caplan and Weintraub 1997) in a case control study found similar results but it was insignificant. They also found that teeth which had long fillings were extracted rather than retained in contrast to short filling which were retained more often than extracted. The previous results show that RCT within 2 mm of the radiographic apex have the best outcomes.
Dr. Gary Silva and his team are highly trained and experienced in providing restorations for all sorts of dental issues.

Another preventive way to help children build stronger teeth is water fluoridation prevents 2/3rd of children from them not getting cavities. (Evans par. 6) Fluoridation benefits children and let alone fifty percent of the dental bills were cut in price. (Evans par.6) The future is looking bright for the children getting better dental and oral health services. Approximately 8.7 million children are expected to gain some form of dental benefits by 2018. (Evans par.8) Regular preventive dental care, such as cleaning and regularly brushing and flossing, improve the overall health and brightens up your life. (Wallace par.1) Keeping up on the regular cleaning at the dental office, which is once every six months, helps out tremendously but some people need more then twice a year. (Payne par.5)
Within this set, the investigators randomized how many trials the participants would complete: 7, 10, or 13. Then, they were giving the chance to do 3 or 6 more trials and were ask to record their results.

Denture teeth can be made of acrylic poly(methyl methacrylate) (PMMA) or composite resins. PMMA is a polymer - a material made the from joining of methyl methacrylate monomers. Properties of PMMA include resistance to abrasion, chemical stability and a high boiling point. (Jun Shen et al. 2011). However, weak flexure and impact strength of PMMA are of concern as they account for denture failure. (Bolayir G, Boztug A and Soygun K. 2013). Composite denture teeth are made of a three distinct phases - filler, matrix and coupling agents. Out of the types of composite teeth available, nano-filled composite teeth are preferred. Composite teeth have a PMMA coating around the tooth and a high content of filler particles. This gives them strength, higher resistance to forces than acrylic teeth and provides compete polymerization due to the PMMA coating. (Anusavice, K. J., Phillips, R. W., Shen, C., & Rawls, H. R, 2012). If the interface between the PMMA denture base and PMMA or composite teeth was weak, the denture will not be able to sustain occlusal forces, making the base-teeth interface, an entity of significance.
Periodontal disease is an infection of the gingiva and alveolar bone. Periodontal disease increases in prevalence and severity as people age. Periodontal disease is precursored by gingivitis.

Impression materials are used to register or reproduce the form and relations of the teeth and the surrounding oral tissues (1). Making an impression represents a critical step in processing and fitting of a dental prosthesis (2). Several types of impression materials are produced. These include silicones, polyether, polysulfide and alginate which are available for crowns and fixed partial denture impressions. Silicone impression materials are considered to be suitable impression materials to use for fixed prostheses (3). Also, it has been reported that silicone has the ability to remain dimensionally stable through disinfection procedures (4). Among silicone impression materials, one type of them, called polyvinyl siloxane (PVS) is reported
...f patients’ doctors recruited participants, patients may not ease to refuse participating a trial. Therefore recruitment may be better to be done by a person who does not normally treat the patients.
Cosmetic dentistry is a specialized field that deals with improving the aesthetics of teeth and the human face. The teeth are an important part of human beauty. Even minor damage to the teeth, such as breakage or loss can drastically alter the overall appearance of the face. This is where cosmetic dentistry comes in to restore beauty. Cosmetic dentistry has become a highly specialized branch due to various advancements in surgical procedures and diagnostic techniques. Several new materials have also been discovered. These materials are very close to the natural enamel and bone from which teeth are made and are virtually indistinguishable. Cosmetic dentistry is an option in conditions such as teeth loss, gaps between teeth, cracked or chipped teeth, cavities and dental
