1. The document discusses proper order and sequencing of periodontal instrumentation. It states that more rigid instruments with rigid shanks should be used first when removing larger calculus deposits, while more flexible instruments with flexible shanks are best for removing smaller deposits.
2. Factors that can cause burnishing of the root surface during instrumentation include using lightweight ultrasonic inserts, flexible shank curets, or dull instruments. Proper sequencing involves using ultrasonics, files, and sickle scalers initially followed by standard curets.
3. The characteristics and uses of various periodontal instruments like files, sickle scalers, chisels, and curets are described. The document emphasizes adapting instruments correctly to the tooth surface

Embracing GenAI - A Strategic ImperativePeter Windle
Artificial Intelligence (AI) technologies such as Generative AI, Image Generators and Large Language Models have had a dramatic impact on teaching, learning and assessment over the past 18 months. The most immediate threat AI posed was to Academic Integrity with Higher Education Institutes (HEIs) focusing their efforts on combating the use of GenAI in assessment. Guidelines were developed for staff and students, policies put in place too. Innovative educators have forged paths in the use of Generative AI for teaching, learning and assessments leading to pockets of transformation springing up across HEIs, often with little or no top-down guidance, support or direction.
This Gasta posits a strategic approach to integrating AI into HEIs to prepare staff, students and the curriculum for an evolving world and workplace. We will highlight the advantages of working with these technologies beyond the realm of teaching, learning and assessment by considering prompt engineering skills, industry impact, curriculum changes, and the need for staff upskilling. In contrast, not engaging strategically with Generative AI poses risks, including falling behind peers, missed opportunities and failing to ensure our graduates remain employable. The rapid evolution of AI technologies necessitates a proactive and strategic approach if we are to remain relevant.

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.

2024.06.01 Introducing a competency framework for languag learning materials ...Sandy Millin
http://sandymillin.wordpress.com/iateflwebinar2024
Published classroom materials form the basis of syllabuses, drive teacher professional development, and have a potentially huge influence on learners, teachers and education systems. All teachers also create their own materials, whether a few sentences on a blackboard, a highly-structured fully-realised online course, or anything in between. Despite this, the knowledge and skills needed to create effective language learning materials are rarely part of teacher training, and are mostly learnt by trial and error.
Knowledge and skills frameworks, generally called competency frameworks, for ELT teachers, trainers and managers have existed for a few years now. However, until I created one for my MA dissertation, there wasn’t one drawing together what we need to know and do to be able to effectively produce language learning materials.
This webinar will introduce you to my framework, highlighting the key competencies I identified from my research. It will also show how anybody involved in language teaching (any language, not just English!), teacher training, managing schools or developing language learning materials can benefit from using the framework.
2. Imagine you’ve just spend 2 hours scaling and root planing a quadrant of moderate sub-gingival calculus. You feel you’ve done a great job and ask for a faculty evaluation. Your evaluation reveals that you have burnished the entire quadrant with your instruments. How can this be? What do you think happened during instrumentation?
4. Effectual Instrument Sequencing “Instrument selection that maximizes periodontal instrument design in a strategic, methodical way. Calculus removal is accomplished utilizing the most effective and efficient use of periodontal instruments. Practical instrumentation involves a progressive pattern that is logical, chronological and systematic.” (Duff, 2009)
5. But first, a bit of review. Pre-requisite: Knowledge of design characteristics of scaling and root planing instruments
6. Instrument Design A. Handle Transmits vibrations B. Shank Joins handle to working end Rigid or flexible C. Working End Contacts tooth Performs task
7.
8. SHANK DESIGN “Instruments are made with shanks of varying degrees of thickness and rigidity that relate to the purpose for which they are used.” (Wilkins, 2009)
9. RIGID SHANK Rigid Thick Shanks – A heavier shank is stronger and is able to withstand greater pressure w/o flexing when applied during instrumentation. Strong instruments are needed for removal of heavy calculus deposits. (Wilkins, 2009) T/F
10. FLEXIBLE SHANK Less Rigid (↑ Flexible) Shanks: A thinner shank may provide more tactile sensitivity and is used, for example, for removal of fine deposits of calculus and for maintenance root debridement. (Wilkins, 2009) T/F
13. Instrumentation Paradigm The larger the piece of calculus, the more rigid the shank. The smaller the piece of calculus, the more flexible the shank. T/F
14. What’s the most flexible exam instrument we use? Shank Characteristics Shank is designed like 11/12 Gracey curette Tip is thin, flexible and tapered Can you remove calculus with an explorer? Why/ why not?
15. Curets – Finishing Instruments A standard universal or area specific curet has moderate flexibility. How will they perform on a small piece of calculus? How will they perform on a medium piece of calculus? How will they perform on a large piece of calculus?
16. 29 Palms – Common Error From Ultrasonic to Universal Curet: A frustrating story……. Moral: Work Smart NOT Hard, folks!
18. Instrument Sequencing Maximize Instrument Design Strategic and Methodical Use Most Effective Efficient Use Practical and Logical progression Logical and Systematic sequence
19. Practical use of Instruments The larger the piece of calculus the more _________the shank? The ________ the piece of calculus the more flexible the shank?
21. y Rigid or Flexible? Rigid or Flexible? Rigid or Flexible?
22. Which insert for? De-plaquing M-H S/S Calc? Avoiding what Power Setting? Lt. S/S Calc? What happens clinically when you use a thin insert on moderate – heavy calculus?
25. 25 Hoe Scalers Work horse prior to USS’s! Hoes - More Rigid
26. 26 Hoe Scalers - Purpose Purpose Gross calculus removal (especially large, accessible, tenacious pieces) Generally supragingivally,OR 2 - 3 mm sub if tissuedisplaces easily Mainly used on facial and lingual of anterior teeth, next to edentulous spaces, or areas with flaccid tissue Replaced by ultrasonic instrumentation and files
27. 27 Hoe Scalers - Contradindications NOT tight tissue due to trauma to pocket wall Adaptation to curved tooth problematic Decreased tactile sensitivity due to bulk Very easy to gouge tooth surfaces!
28. 28 Hoe Scalers - Applications Modified pen grasp Appropriate fulcrum Full width of cutting edge adapted avoids trauma and gouging Cutting edge to tooth angle= 90° Vertical coronal pull stroke Follow up with curets
29. 29 Hoe Scalers Must avoid line angles! Hoes - More Rigid
30. Hoes - More Rigid Designs accommodate Direct and Proximal surfaces
37. 37 Files - Characteristics Multiple parallel straight cutting miniature hoe blades Cutting edges 99° to 105°angle to the base Bases are varying sizes & shapes (round, oval, rectangular, spade) and rounded backs = SubG ok Various shank lengths, angulation, and size Usually double-ended, paired instrument M/D, B/L
38. 38 Files - Purpose Crushing, fracturing or roughening S/S Calc. Gross S/S removal or burnished calculus Deep, narrow pockets where length/curve of curet blade will not fit Palatals of maxillary anteriors M/D concavities of mandibular molars or cuspids B/L of Molars or Bi’s Smooth rough CEJ’s Root planing using “finishing files” challenging in deep areas Smoothing restoration margins or removing overhangs
39. 39 Files - Contraindications Cannot be used tight tissue due to trauma to pocket (wide bulky base) Adapt flat working surfaces to curved tooth surfaces Straight, rigid terminal shank = limits in deep curved roots Decreased tactile sensitivity because of bulk Very easy to gouge tooth surfaces!
40. 40 Files - Applications Modified pen grasp Appropriate fulcrum Full working surface adapted flat to tooth avoid trauma/gouging Vertical coronal pull stroke Follow up with curets
46. 46 Chisels - Purpose Gross supragingivalcalculus removal no interdental papillae Removal of heavy “bridges” of interproximal calculus from lower anteriors Limited application elsewhere Not in common use; replaced by ultrasonics
47. 47 Chisels - Contraindications Contraindicated for Sub G. (NO) Difficult to adapt straight blade to curved tooth surfaces Decreased tactile sensitivity – bulky Very easy to gouge
48. 48 Chisels - Applications Modified pen grasp Palm-thumb grasp Appropriate fulcrum Full width adapted to tooth avoiding trauma /gouging
49. 49 Chisels Working stroke is horizontal “push” stroke only Perpendicularto long axis of tooth Interproximally - Insert from facial aspect and activate push stroke towards lingual Follow up with curets
54. Sickle Scalers - Purpose Healthy tissue – Supra-G ONLY Spongy, loose, flexible tissue – gross Sub-G OK When calculus is continuous with Supra –G Wilkins, 2009
55. Sickle Scalers - Contraindications Sub-gingival use is contraindicated in healthy gingiva. Can cause undue gingival trauma due to (Blade: size, thickness and length) Pointed tip can NOT be easily adapted line angles Not as likely with curved posterior sickles ↑Risk of grooving /scratching cemental surface Tactile sensitivity ↓ (Blade: larger, heavier) Mini Sickles – Apically to contacts (Morse Sickles) Wilkins, 2009
66. Curets - Purposes Standard instrument for Sub G removal SRP Removal of Supra G Especially fine deposits near gingival margin Supra commonly seen in pedo pts. Rounded tip – best suited to cervical area Round back – no trauma to pocket wall Used after gross debridement w/ USS >>> Scalers (Files and Sickles) >>> Cure Soft Tissue Curettage
67. Curets - Contraindications Not preferred choice for M-H Sub G Not recommended for burnished deposits Not recommended for gross debridement Flexible shank design will “skip” over larger deposits = burnishes
83. Summary Basic Order of Instrumentation The larger the deposit the rigid the shank Debridement Heavy deposit removal Crushing, fracturing, roughening deposits Reduced tactile sensitivity The smaller the deposit the more flexible the shank De-plaquing and/or scaling (especially pediatric pts.) Lt. to Mod. deposit removal only Smoothing, root planing Increased tactile sensitivity
84. LLUSD – Standard DH Issue More Rigid Instruments - First in SRP cases Ultrasonics (Medium inserts on higher power settings) Files – (Non-finishing types) Sickles – (SRP patients with spongy, flexible gingiva_ Rigid Curets – (Universals, Area Specifics) More Flexible Instruments – Second in SRP cases Standard Curets (Universals, Area Specifics) Area Specifics w/ extended shanks Area Specifics w/ mini bladed Thin and ultra thin ultrasonic inserts
