Porcelain Laminate Veneers: Indications and Contraindications

Indications:

1. Used on slightly/mildly enlarged teeth
2. Traditionally indicated in aesthetic areas where a single crown composite resin veneer would be used
3. To correct diastemas
4. Masking of discolored/stained teeth
5. Repairing enamel defects

Contraindications:

1. Cannot be waxed on short clinical crowns
2. Not suitable for patients with parafunctional habits (e.g., bruxism)
3. Teeth with insufficient enamel for adequate retention
4. Teeth with large restorations or endodontically treated teeth with little remaining structure
5. Patients with tooth wear due to bruxism

Human Nutrition: The Digestive System

Human nutrition involves several key systems: digestive, respiratory, circulatory, and excretory.

Preparation for Digestion

This phase consists of three main parts:

Insalivation

Insalivation involves saliva, a watery substance containing amylase enzymes that break down simple carbohydrates. Saliva is produced in three salivary glands: sublingual, submandibular, and parotid. The tongue, a muscular organ covered in taste buds, helps mix food with saliva, allowing us to taste food.

Mastication

Mastication consists of breaking down food into smaller pieces to ease digestion. Types of teeth include incisors, canines, molars, and premolars. Humans have 20 milk teeth and 32 adult teeth.

Swallowing

Swallowing involves two... Continue reading "Understanding Human Nutrition: Digestive System Essentials" »

Post-War British Literature: A Look at The Movement and Beyond

The Cultural Landscape of Post-War Britain

The cultural landscape of the post-war period reflects a sense of fragmentation and absurdity, echoing the punk and anarchist movements and exemplified by the Theatre of the Absurd. This existential futility is underscored by the trauma of events like the atomic bombing of Hiroshima and Nagasaki.

Consumerism created an illusion of prosperity, masking widespread disillusionment. This disappointment found its voice in the writings of the Angry Young Men.

The Angry Young Men

These writers, often from working-class backgrounds, found themselves alienated from both the middle and working classes. Key figures included John Osborne, John Braine, and... Continue reading "Post-War British Literature: A Look at The Movement and Beyond" »

Respiratory System Basics

Respiratory Key Terms

• Dyspnea: Difficulty breathing
• Orthopnea: Difficulty breathing when lying flat
• Tachypnea: Abnormally fast breathing
• Bradypnea: Abnormally slow breathing
• Hemoptysis: Coughing up blood
• Hypoxia: Tissue oxygen deficiency
• Clubbing: Fingertip rounding due to chronic hypoxia
• Barrel chest: Increased chest diameter often from emphysema
• Cyanosis: Bluish skin or mucous membrane discoloration from low oxygen
• Rales/Crackles: Abnormal lung sounds indicating fluid
• Wheezing: High-pitched whistling from narrowed airways
• Rhonchi: Low-pitched rattling sounds (often due to secretions)
• Productive cough: Cough producing mucus or sputum
• Hypertonia: Increased muscle tone causing stiffness
• Hypotonia: Decreased muscle tone making muscles

Steps in Root End Surgery

• Local anesthesia and hemostasis
• Management of soft tissue
• Management of hard tissue
• Surgical access (visual and operative)
• Access to root structure
• Periradicular curettage
• Root end resection
• Root end preparation
• Root end filling
• Soft tissue repositioning and suturing
• Post-surgical care

Root End Preparation

Preparing a cavity to receive root end filling.

According to Carr and Bentkover, this involves a Class I preparation at least 3mm into root dentin with walls parallel to and coincident with the anatomic outline of the pulp space.

Key requirements:

1. The apical 3mm of the root canal must be freshly cleaned and shaped.
2. The preparation must be parallel to and coincident with the anatomic outline of the pulp space.
3. Adequate retention form

Mineral Trioxide Aggregate (MTA) Applications

Pulp Therapy

• Pulp capping
• Furcation repair
• Strip perforation repair
• Root resorption repair
• Immature teeth
• Root end filling material

Elements of Pulp Regeneration

Therapy for exposed dental pulps using stem cells and a biofunctional scaffold, inhibiting or eliminating infection to facilitate pulp generation.

Nickel-Titanium (NiTi) Rotary Instruments

Advantages of NiTi Reciprocation

• Mimics manual movement
• Reduces risks associated with continuous rotation in curved canals

Types of Posts

1. Carbon fiber epoxy resin posts
2. Zirconia posts
3. Glass fiber reinforced posts
4. Ultra-high strength polyethylene fiber reinforced posts

Advantages of NiTi Rotary

• Gradual, evenly tapered radicular preparation
• Fewer instruments required
• Reduced

Common Medical Abbreviations

• RSI: Repetitive Stress Injury
• SAD: Seasonal Affective Disorder
• SIDS: Sudden Infant Death Syndrome
• GP: General Practitioner
• HAV: Hepatitis A Virus
• MD: Medical Doctor

Medications and Treatments

• Decongestant: Decreases nasal stuffiness and relieves a runny nose.
• Anticoagulant: Prevents or delays blood clotting.
• Sedative: Relieves symptoms of stress, irritability, or excitement.
• Laxative: Relieves constipation.
• Digitalis: Strengthens the failing heart.
• Diuretic: Removes excess fluid from the body.
• Antibiotic: Treats infections caused by bacteria and other microorganisms.
• Insulin: Regulates the level of sugar in the blood, used to treat diabetes.

Common Symptoms and Their Causes

• Fainting, dizziness: Anemia
• Headache: Sinus infection
• Fever:

5. Describe what is electrodeposition, describe the different Experimental methods. Give examples. Advantages and disadvantages. It is the process of production a coating, usually Metallic, on a surface by the action of an electric current._Experimental Methods::-Electroplating: It is a plating process in which metal ions in a Solution are moved by an electric field to coat an electrode. Metallic cations From a solution are reduced on a conductive object (to form a thin layer).-Electrophoretic Deposition:Colloidal particles suspended in a liquid migrate under the Influence of an electric field (electrophoresis) and are deposited onto an Electrode._Advantages: uniform coating thicknen,easy control,high speed of Coating and high pucity._Disadvantages:
