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).

Dental pulp is the center part of the tooth and is made of tissue and nerves. Dentin is connected to the dental pulp and is the second hardest part of the tooth. Enamel is the hard, outer layer that surrounds the tooth. Enamel cannot be repaired or replaced. One can only prevent its loss, which is why we
Forensic odontology is becoming a more ubiquitous method of human identification following gruesome deaths, disasters, and crimes. Usually, the first step in forensic odontology is the comparison of antemortem (before death) dental records and postmortem (after death) dental records (Source 1). Antemortem dental records are useful to match the victim with the cadaver; for instance, if a known person is missing and a body is found, forensic odontologists are able to examine the dental status of the

Introduction The use of snuff is widespread in the recent years, especially among male adolescents and young adults. Snuff was first introduced in Europe in the 17th century and it was inhaled through the nostrils in dry form, but nowadays most snuff is moist and taken orally (Asplund, 2002). Snuff use, as an issue, has been a great concern to many researchers. A handful of studies have been conducted in this area to find out the factors that may contribute to such a phenomenon as well as to identify
People vary considerably in their tendency to form and accumulate dental stains and surface debris—as well as in their desire for white teeth. It has been long recognized that brushing with just a wet brush has little influence on stain removal within the typical one to three minutes of twice daily brushing.

ASSIGNMENT Najla Manis Al-shahrani 432802924 Periodontal versus pulpal abscess The relationship between periodontal disease and pulpal infection occurs primarily by the intimate anatomic and vascular interactions between the pulp and the periodontium. As such, when we as dentists see these periapical lesions affecting the periodontium and the apical tissue, proper diagnosis and treatment is of utmost importance if we are to give the affected tooth a hopeful prognosis.
