Uses of ethoxy benzoic acid in dental cement It is an organic compound derived from Benzoic acid. 2-Ethoxybenzoic acid is a dental cement mostly used for root-end filling and prevents entry of pathogens in the periapical region. It has a molecular weight of around 166.17g/mol. It Provides mechanical interlocking in the compounds of ethoxy benzoic acid which gives strength and hardness to the material for gap filling or restoration. It is an organic compound crystalline, colorless solid under natural conditions.  It is also used as a ph controller and prevents the growth of pathogens or microbes in the mouth or oral cavity to keep food safe. Benzoic acid is also used in mouthwashes to prevent bad breath as well and also used for luting of the metal prosthesis, sealing, and filling, bridgework, pulp capping, and cementing media for crown and bridgework. Ethoxy benzoic acid provides interlocking and chemically bond with the natural teeth easily for giving a natural look.    

 Is there any role of pH in the absorption of  caries detector dyes on the dentinal surface? What is a caries detector? These dyes selectively stain infected demineralized dentine if so it acts as a clinical guide to remove irreversible decalcified tissue. Mainly used to diagnose occlusal caries. Here we describe the application of the Ir/IrOx pH sensor, which is used to detect the pH of caries dentinal surface. The pH level is to distinguish between active and arrested caries. The average pH values of active caries, arrested caries, and the sound root 6.85, 6.05, 5.30 respectively. This caries testing technique using Ir/IrOx sensor gives accurate quantitative caries evaluation.  What we eat, drink, change the pH level in our mouth which is responsible for an optimal environment for Bad breath which can cause caries in the tooth.  When the pH level falls below the normal level, demineralization occurs. when teeth get bacteria, the oral cavity starts to release lactic acid which is the

 My teeth are not coming in the Age of    the month of 13 I'm worried about what I can do? This is one of the questions usually asked so I'm here to answer this. Humans have two sets of teeth in their lifetime. The first set of the seen in the mouth is the primary or deciduous dentition, which begins to form prenatally at about 14 weeks in utero and completed postnatally at about 3 years of age first dentition begins to appear in the mouth at about 6months of age or typically 7-11 months of age and remains up to 6 years of age after that transition period starts in which deciduous (milk) teeth fall then permanent teeth comes up to 12 or 13 years of age normally and completes 28 sets of permanent dentition but some children are late bloomers.  It can be caused due to-  poor nutrition- if the child doesn't get proper breast milk to fulfill his body needs, hyperthyroidism, hereditary or insufficient space in dental arches, dental infection.  And if this condition pursues then

  Enamel Enamel is the highest mineralized tissue of the body and totally acellular. Enamel is brittle and subject to fracture by trauma or heavy sharp-edge forces. It is a semi-permeable membrane permeable to some fluids, bacteria, and their products. Enamel is the hardest substance of the body, it can withstand blunt, heavy masticatory forces. It has a low tensile strength.  Composition- 96%- Inorganic matrix. 4%- Organic matrix:-  1. 90% Amelogenins- rich in proline,                                                                histidine, glutamine & leucine.                                                         2. 10% Non- amelogenins- Enamelin,                                                               tuftline, ameloblastin.  Structure- 1. Rods- It is a long, thin structure extending from the Dentino enamel junction to the surface of the enamel. 2. Rod Sheaths- It is a thin layer seen peripheral to the rods. It also contains organic fibrils. entre of the rod is called

Dentine Dentine is  somewhat elastic, yellowish, and mineralized avascular tissue supports the enamel and encloses the pulp chamber. Composition of dentine- 60% Inorganic appetite 40% Fibrillar protein collagen or 70% apatite 20% collagen  10% of water The formation of dentine is known as dentinogenesis. Odontoblasts cells produce dentine. The function of dentine is to support and protect the enamel from enamel fracture and masticatory forces. It also protects the pulp from other harmful microbial and other harmful stimuli. Types of dentine- 1. Predentine. 2. Secondary dentine. 3. Tertiary dentine. It is harder than bone and softer than enamel consists of apatite crystals. If dentine gets exposed it can cause sensitivity due to cold, heat, acidic or sticky substance reaches inside the tooth causing pain. Sensitivity can cause Sceviour pain and other disease, heart problems. This problem of sensitivity can be healed by brushing with fluoride-containing toothpaste twice a day.      

 Let's learn some more about Cells of Pulp As I already discussed pulp in my previous blog Today I will tell you about Cells present in the pulp tissue in detail. CELLS- Odontoblasts These are the second most prominent cells in the pulp and lies in the periphery of the pulp adjacent to the predentine also called the " odontogenic zone of the pulp".  The shape of odontoblast in the tooth pulp - Tall and columnar in the crown portion.  Cuboidal in the middle of the root. Flat and Spindle shape in the apex of the root. Odontoblast is approx 5-7 microns in diameter. Fibroblasts These are the cells that occur in the greatest amount in the pulp tissue. The function of these cells is to form college fiber and ground substance and maintain them throughout the life of the pulp.  But it also has the ability to ingestion and degradation of collagen fiber and ground substance. The Shape of the cells- Stellate shaped cells having extensive processes that communicate with the processes
