SUBJECT: Introduction To Dental Drugs and Dental Surgery 1.Define sterilization.Write down the principal,advantage and disadvantage autoclave? Definition: Sterilization is the process by which all viable microorganism including their spore are killed or eliminated. Principal of autoclave: Steaming at a higher than 100°c, here temperature of boiling upon the surrounding atmospheric pressure. A higher temperature of steaming is obtained by employing a higher pressure. When the autoclave is closed and made air tight then water starts boiling .The inside pressure increase and now the water boils above 100°c.

Source:a. Natural source:-Exposure to sunlight b. Vegetable source: - vegetable oil -Yeast - Ergot c. Animal source: - Cod liver oil -Haliver liver oil -Liver Function:1.It helps in absorption of calcium and phosphorus from the intestine. 2.It helps in calcification of new bone 3.It helps in development of normal teeth 4.It is necessary for proper growth of bone and skeletion Deficiency disorder: 1. Rickets: Bone deformities. 2. Osteomalacia:Softened bones. 3. Increased fracture risk. 4. Muscle weakness. 5. Reduced immune function. 14.Vitamin C Vitamin C, also known as ascorbic acid, is a water-soluble vitamin that plays a crucial role in various bodily functions. Vegetable source:- Animal source:- 1. Fresh citrus fruitsa. Amloki b. Orange c. Lemon d. Guava 2. Fresh citrus vegetables source:i. Cabbage ii. Beans-Caulis flower 1. Milk 2. Meat 3. Fish Diseases: 1. Scurvy. 2. Impaired immunity 3. Delayed healing 4. Anaemia 5. Weak blood vessels. Function: 1.It maintains the cementing substance of the capillary endothelium. 2.It takes part in wound healing. 3.It has some metabolic action. 4.Large dosage protect against information. 5.It prevents scurvy. 15.Dental X ray Dental X-ray is a diagnostic imaging technique that uses low levels of radiation to capture detailed images of teeth, bones, and surrounding tissues to assess dental health and identify potential issues. Indication:OPG’S indication Classification: A) Intra-oral radiographya. Peri-apical radiography b. Inter-proximal radiography or bite wing c. Occlusal radiography B) Extra-oral radiographya. Lateral oblique view b. Lateral cepholometry c. Panoramic radiography 16.IOPA X-Ray Definition: IOPA(Intra Oral Periapical) X-Ray is a dental imaging technique used to capture detailed images of the teeth, surrounding structures, and jawbone to aid in diagnosing dental conditions. Types: 1. Periapical X-ray: This type of IOPA X-ray focuses on capturing a single tooth from the crown to the root, including the surrounding bone structure. 2. Bitewing X-ray: Bitewing X-rays show the upper and lower teeth in a specific area. These X-rays help in detecting cavities between the teeth and assessing the fit of dental restorations. 3. Occlusal X-ray: Occlusal X-rays provide a broad view of the upper or lower jaw, showing the entire arch of teeth and their position in relation to each other. Indication:1.Size and shape of the teeth 2.External root resorption 3.Internal root resorption 4.Position of permanent tooth germ 5.If bone resorption present 6.If any lesion in periodontal/supporting structure. 7.Depth of the lesion 8.Furcation area 9.Pulp calcification 17.Impacted 3rd molar-Define impaction,cause,classify with diagram Impaction: An impacted tooth is which fails to erupted into dental arch within the erupted time.This is unerputed tooth is called impaction/impacted tooth. Cause of impaction: A) Local causes are1.In the teeth are large in size in relation to the arch 2.Irregularity in position on pressure from adjacent tooth 3.The density of over line on surrounding bone 4.Lack of space due to under development 5.Density of mucous membrane B) Systemic causes are1Pre-natal -Cleft lips -Cleft plate 2.Post-natal -Rickets -Anaemia - Tuberculosis -Congenital -Endocrine dysfunction Classification of 3rd molar: 1.Vertical impaction 2.Horizontal impaction 3.Inverted impaction 4.Mesio angular impaction 5.Disto angular impaction 6.Lingo angular impaction 18.Operculectomy The nearly erupted mandibular 3rd molar may have a dense fibrous, operculum covers two 3rd or less of its occlusal surface.Frequently this tissue is the source of discomfort to the patient,because it may be inflamed either as the result of masticatory trauma from the opposite maxillary 3rd molar or because of infection resulting from the growth of bacteria in the ideal incubation that lies beneath its covering. This condition is known as pericoronitis. Operculectomy is indicated in this condition. The efficient method for removing the dense fibrous mucoperiosteal tissue is to be used radio surgical loop. The loop placed beneath the operculum as for posterior as the loop can be inserted around the distal surface of the tooth. When it is reached this position the loop is turned on & it is moved superiorly. This cut off the bulb of the tissue distally. It is necessary plan by placing the loop on the crest on the tissue approximately 5cm distal to the crown & cutting down wards, towards the gingival line.
