Orthodontic Treatment Modalities Done by: Dr. Mohamad Ghazi Kassem
2. Orthodontic Treatment Modalities Preventive orthodontics: Interceptive orthodontics Corrective orthodontics • Removable appliances • Fixed appliances Orthognathic Surgery “Jaw Surgery”
3. Preventive orthodontics Preventive Orthodontics is the action taken to preserve the integrity of what appears to be normal at a specific time. Any procedure that attempt to ward off untoward environmental attacks or anything that would change the normal course of events, e.g. 1. Early connection of proximal caries that might change the arch length 2. Early recognition and elimination of oral habits that might interfere with the normal development of the teeth and jaws 3. Placing of a space maintainer to maintain proper position of contiguous teeth It is defined as the action taken to preserve the integrity of what appears to be a normal occlusion at a specific time.
4. 1960 : Kesling stated that “some case should be referred as early as 3 or 4 years of age and all cases by the age of 8 or 9 years” there by lying the foundation of preventive and interceptive orthodontics. 1977: Begg stated that “proper time to begin the treatment is as the beginning of the variation from the normal, in the process of development of dental apparatus, as possible” 1980: Profit and Ackermann has defined it as a prevention of potential interference with occlusal development.
5. Various Preventive procedures are : 1. Pre-dental procedures 2. Care of deciduous dentition 3. Patient and parents education programs 4. Supernumerary teeth 5. Early loss of deciduous teeth 6. Proximal caries 7. Oral habits 8. Space maintainers
6. 1. Pre-dental procedures: • Proper nutrition of the child. • Proper nursing care of the infant. • Bottle feeding should be discouraged.
7. 2. Care of deciduous dentition: 3. Patient and parent’s education programs: Need of maintaining good oral hygiene should be explained to the patient and the parents. Demonstration of brushing methods and diet counseling etc are also important.
8. 4. Supernumerary teeth: Supernumerary teeth and supplemental teeth can interfere with the eruption of nearby teeth. Presence of mesiodens prevents the two maxillary central incisors from approximating each other. They should be removed at appropriate time.
9. 5.Oral habits: Abnormal oral habits should be recognized and patient should be helped by motivation or by fitting a suitable habit breaking appliance.
10. digit sucking Methods to prevent tongue thrusting Mouth breathing
11. 6.Space maintainers: Premature loss of deciduous teeth can cause drifting of the adjacent teeth into the space. Space maintainers must be inserted in appropriate cases after the loss of teeth, particularly after the loss of deciduous molars in inadequate arches. Fixed Space Maintainers Removable space maintainers

Operation “Blue Star” is the only event in the history of Independent India where the state went into war with its own people. Even after about 40 years it is not clear if it was culmination of states anger over people of the region, a political game of power or start of dictatorial chapter in the democratic setup.
The people of Punjab felt alienated from main stream due to denial of their just demands during a long democratic struggle since independence. As it happen all over the word, it led to militant struggle with great loss of lives of military, police and civilian personnel. Killing of Indira Gandhi and massacre of innocent Sikhs in Delhi and other India cities was also associated with this movement.

How to Create Map Views in the Odoo 17 ERPCeline George
The map views are useful for providing a geographical representation of data. They allow users to visualize and analyze the data in a more intuitive manner.
We all have good and bad thoughts from time to time and situation to situation. We are bombarded daily with spiraling thoughts(both negative and positive) creating all-consuming feel , making us difficult to manage with associated suffering. Good thoughts are like our Mob Signal (Positive thought) amidst noise(negative thought) in the atmosphere. Negative thoughts like noise outweigh positive thoughts. These thoughts often create unwanted confusion, trouble, stress and frustration in our mind as well as chaos in our physical world. Negative thoughts are also known as “distorted thinking”.
The French Revolution, which began in 1789, was a period of radical social and political upheaval in France. It marked the decline of absolute monarchies, the rise of secular and democratic republics, and the eventual rise of Napoleon Bonaparte. This revolutionary period is crucial in understanding the transition from feudalism to modernity in Europe.

The Roman Empire A Historical Colossus.pdfkaushalkr1407
The Roman Empire, a vast and enduring power, stands as one of history's most remarkable civilizations, leaving an indelible imprint on the world. It emerged from the Roman Republic, transitioning into an imperial powerhouse under the leadership of Augustus Caesar in 27 BCE. This transformation marked the beginning of an era defined by unprecedented territorial expansion, architectural marvels, and profound cultural influence.
The empire's roots lie in the city of Rome, founded, according to legend, by Romulus in 753 BCE. Over centuries, Rome evolved from a small settlement to a formidable republic, characterized by a complex political system with elected officials and checks on power. However, internal strife, class conflicts, and military ambitions paved the way for the end of the Republic. Julius Caesar’s dictatorship and subsequent assassination in 44 BCE created a power vacuum, leading to a civil war. Octavian, later Augustus, emerged victorious, heralding the Roman Empire’s birth.
Under Augustus, the empire experienced the Pax Romana, a 200-year period of relative peace and stability. Augustus reformed the military, established efficient administrative systems, and initiated grand construction projects. The empire's borders expanded, encompassing territories from Britain to Egypt and from Spain to the Euphrates. Roman legions, renowned for their discipline and engineering prowess, secured and maintained these vast territories, building roads, fortifications, and cities that facilitated control and integration.
The Roman Empire’s society was hierarchical, with a rigid class system. At the top were the patricians, wealthy elites who held significant political power. Below them were the plebeians, free citizens with limited political influence, and the vast numbers of slaves who formed the backbone of the economy. The family unit was central, governed by the paterfamilias, the male head who held absolute authority.
Culturally, the Romans were eclectic, absorbing and adapting elements from the civilizations they encountered, particularly the Greeks. Roman art, literature, and philosophy reflected this synthesis, creating a rich cultural tapestry. Latin, the Roman language, became the lingua franca of the Western world, influencing numerous modern languages.
Roman architecture and engineering achievements were monumental. They perfected the arch, vault, and dome, constructing enduring structures like the Colosseum, Pantheon, and aqueducts. These engineering marvels not only showcased Roman ingenuity but also served practical purposes, from public entertainment to water supply.
