Molar

male horses possess forty teeth when fully mature while females possess thirty-six. The most highly studied characteristic of any member of the Equidae family are the sets of teeth and the different types of teeth: the incisors, the cheek teeth (the molars and premolars), and in some cases, the canines or wolf teeth. Many people have proposed that the evolution of equine’s teeth and mouths was due to a change in diet from browsing to grazing as forests were gradually replaced by grasslands.…

Wisdom teeth received their name because they erupt much later in life than other teeth. Despite what their name suggests, though, wisdom teeth are neither wise nor superior to other molars. In reality, they're more problematic and less useful than their pearly white neighbors. Listed below are five reasons to have your wisdom teeth removed soon. 1. Wisdom Teeth are Prone to Tooth Decay Thanks to their location in the very back of your mouth, wisdom teeth are difficult to clean properly.…

The wisdom tooth is any of the four hindmost molars found in humans. They normally appear during the early 20’s or late teens. It is also defined as the third molar that is the last tooth to erupt on each side of the upper and lower jaws in humans. Normally the teeth erupt and cause no harm or discomfort to the patient. The most common problem that arises is an impacted wisdom tooth (which happens when there is not enough room for the tooth to grow). As a result, the tooth either grows…

Our paper is about sunscreen, oncology, and cancer and how it relates to chemistry. It tells you what sunscreen is, how it affects the body, and what cancer and oncology are. The purpose of this paper is to show what we know and understand about chemistry. We show that we know how chemistry is used in everyday life and how it is in things we use on a daily basis, such as sunscreen. Studies have shown that sunscreen, cancer, and oncology are all related. When using sunscreen daily, you can easily…

The purpose of this experiment was to use aldol condensation methods to synthesize colored cyclopentadienone and then UV/VIS spectrophotometry to characterize the dienone structure synthesized. The information gathered from the UV/VIS analysis was then compared to a computer model of the desired product to analyze the optimal 3D structure of the dienone. The base catalyzed condensation reaction was used to form the product for analysis, followed by vacuum filtration to recover the product. Both…

Atoms and Mocules I. Aim: - To determine the definition of atoms and molecules and the difference of those notions. - Understanding isotopes, atomic mass, and molecular mass. - Understanding mole concept and molar mass. III. Definitions: 1. Atoms: According to Dalton’s atomic theory, atoms are the basic units of matter and the defining structure of elements. Atoms are made up of three parts: protons (positively charged), neutrons (uncharged) and electrons (negatively charged). For…

Hydrogen Peroxide Decomposition Lab Report Objective: By utilising the catalyst of potassium iodide to trigger a decomposition reaction in hydrogen peroxide, how will fluctuation in temperatures will affect the decomposition rate? Hypothesis: Due to the decomposition effect of potassium iodide on hydrogen peroxide, the increased temperature applied will also increase the decomposition rate, because of the more occurrences of collisions which causes the more energy to be produced. Independent…

difficult to remove and require more bone removal. For mandibular molars, we need to be aware of where the inferior alveolar nerve is located and also make sure that we do not perforate the lingual plate with our handpiece which protect us from damaging the lingual nerve. For maxillary molars, we must be aware of where the maxillary sinus is in relation to molars. We don’t want to apply to much apical pressure and displace the maxillary molars into the…

Introduction: In this experiment, the molar mas of the chemical used for combustion in a lighter will be determined by using several methods. A flask will be filled to its max capacity and then filled with that gas. After that, the ideal gas law will be used to find mm (the molecular mass of a substance). The equation will be changed to mm=gRT/PV instead of the usual PV=nRT. There are several gas laws exhibited in this experiment. Dalton’s Law of Partial Pressures allows us to determine the…

absorbance of sample A3 and B3 and their diluted versions, the following graphs can be drawn: Figure 2- A graph showing the relation between concentration of bromophenol blue in M and their absorbance for the acidic form of the molecule, showing the molar absorptivity constant of the molecule at wavelengths 440 nm and 590 nm. The reading with concentration 6 x 10-4 M at wavelength 440 nm was discarded as it is too off from the trend line that it is not following the trend at all. The…
