Extraction of Teeth involves removing teeth from the mouth. There are two main methods - intra-alveolar extraction which uses dental forceps, and trans-alveolar extraction which uses surgical techniques. Proper technique is important to remove the tooth with minimal trauma. Factors like tooth condition, location in the mouth, and related anatomy determine the appropriate tools and extraction method used.

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.
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.

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.

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.

28. Techniques of Extraction
1- INTRA-ALVEOLAR EXTRACTION
FORCEPS or CONVENTIONAL
This is by using dental forceps and
elevators.
2- TRANS-ALVEOLAR EXTRACTION
This is by using Surgical technique
35. Requirement of the Dental Forceps
INTRA-ALVEOLAR EXTRACTION
All forceps has blades
and handles united by a
hinge joint.
1-The handles must
possess a suitable size to
rest comfortably in the
operator’ s hand and
should long enough to
afford use of strong and
steady extraction
movements. Also it must
be suitable in shape and
design to suit the area of
the tooth.
38. INTRA-ALVEOLAR EXTRACTION
2- The blades must be
sharp to be introduce
under the free gum
margin. In multirooted
teeth the blades should
be designed to grip the
different root patterns
The angulation design of
the blades in relation to
the joint and handles
should be made to
facilitate gripping of the
tooth at CEJ
39. 3-The joint of the
dental forceps must
have free movement
for easy manipulation
but must be free from
rolling movement
Parts of dental forceps
A-Blades
B-Joint
C-Handles
40. Tooth Extraction Forceps
Instruments are varied based on
Crown

Woodson 1
Freer elevator
44. Rules of using dental forceps
1-The patient is seated comfortably in the
chair after adjusting the chair to the
appropriate height , the apron fitted
around the patient and aseptic technique
should be followed , inspecting the tooth to
be extracted and the instruments required
for operation are selected
45. Rules of using dental forceps
2-The forceps are then picked up in the
operator’ s right hand with the thumb
finger supporting it at its joint and the
forceps handles in the palm of the hand
this position gives the operator firm grip
and fine control over the instrument
46. Rules of using dental forceps
In the upper molar and premolar forceps the
curved side of the handles should rest in the
palm of the hand
3-In extraction of maxillary teeth , retract the lip
and cheek and support the alveolar process
using the thumb and index finger of the left hand
4-In extraction of the left mandibular teeth , the
middle and the index fingers of the left hand
grips and supports the alveolar process around
the tooth being extracted, while the thumb is
used to support the mandible
47. Rules of using dental forceps
In extraction of the right mandibular teeth
the operator should stand at the right side
and behind the chair and the left hand
comes from the other side to support the
alveolus with the thumb and index fingers
while the other fingers support the
mandible
48. Rules of using dental forceps
The displacement of the tooth from its socket : When the
blades have been forced along the root with firm grip and
the tooth movement buccal outward and lingual inward
with pressure that should be firm smooth and controlled
Accordingly the outward movement is initiated in the
extraction of all the maxillary and mandibular teeth with
exception of mandibular third and relatively mandibular
second molars .
Inward movement is initiated in the extraction of lower 2 nd
and 3rd molars due to the fact that the lingual alveolar
bone plate is thinner than in the buccal plate .As a
general rule the movement is initiated towards the least
resistance site.
49. Rules of using dental forceps
However there might be some deviation
from the general rule , when the tooth is
involved in very deep decay or abnormal
configuration of root .
In deeply decayed teeth it is advisable to
initiate the extraction movement towards
the decayed side of the tooth and keeping
the force of movement more stressed
towards decayed side
50.
51. Rules of using dental forceps
In extraction of teeth with conical roots
which usually the upper central incisors
and the lower second premolars and
mesiodens, these teeth could be detached
from their sockets by primary rotatory
movement. If such a tooth felt to resist
rotation it should be moved buccolingually.
Also rotatory secondary movement could
be used after the tooth has been
completely loosened.
52. Rules of using dental forceps
The final movement of the tooth: normally after
few buccolingual movements, the tooth is felt to
have been loosened and rising out of its socket ,
when this occurs the final movement should
always be directed outward in order to avoid
traumatizing the teeth of opposing jaw.
If gum is found to be attached to the tooth this
adhesion should be carefully dissected and
avoid pulling of the tooth by dental forceps to
avoid soft tissue laceration and exposure of the
alveolar bone
53. Extraction of maxillary
incisors
A-Apical grip

60. Rules of using dental forceps
• Catch the root not
the crown
• Parallel to the long
axis of the tooth
• Initial movement
• Deep grip
• Firm grip
• Principal movement
• Final movement
61. Mechanical principles involved in
tooth extractions
Applying displacing
force to a tooth:
Direct
application of a
forceps
Indirect via a
fulcrum
(elevators)
Expansion of the
socket
79. … Take time to laugh
It is the music of the
!heart
80. Removal of Fractured Root
Fractured root should be removed at the time of
extraction because it may cause the following
complication:
1-Large roots in the alveolus will be localized
source of inflammation
2-It may cause residual infection
3-RR may act as a mechanical irritant and set up
an inflammatory reaction which may give rise to
neuralgic pain of obscure origin
81. Reason of Root Breakage
1-Faulty application of instruments or
extraction movements, wrong pattern
forceps on a particular tooth may
cause its breakage. Improper grip ,
inadequate extraction movements.
Sudden or jerky extraction movement,
gripping of the crown too superficially
and not at CEJ
82. Reason of Root Breakage
2-Pulpless teeth, badly decayed, teeth with
abnormal root pattern or Hypercementosis
3-Excessive density of the surrounding bone
due condensing osteitis , or isolated tooth
and in old age patient
4-Lake of perfect control of instrument or
interference from the patient
83. Removal of broken single
rooted teeth
• This includes the maxillary incisors and canines
and mandibular incisors, canines and premolars:
• Removal of Roots Broken at the Gingival
Margin:
• A-These root may be extracted with forceps ,
with careful adaptation of the beaks under the
gingival margin
• B-Straight Apexo elevator or Coupland .The
angulated Apexo elevator used to remove
mandibular single rooted teeth apply moderate
force distal as will as mesial of the root till
complete delivery of the RR
84. Removal of the root broken
halfway of the apex
• Generally, these are
the cases which
require the reflection
of mucoperiosteal flap
and removal of buccal
and lingual alveolar
bone what we call it
TRANS-ALVEOLAR
SURGICAL
EXTRACTION
85. Take the time to
… !hear
It is the power of
Intelligence
86. Removal of Roots of Upper and
Lower Molars
• 1-Removal of Broken Root of
Mandibular Molars :
1-When both roots are fractured at the
gingival line , the root trunk is still
present a lower premolar forceps can
be used, its beaks should be inserted
as far under the gingival margin
87. Removal of Roots of Upper and
Lower Molars
• 2-The other technique for removal of such
roots is a drill used to separate the roots
after this Apexo elevator may be used to
loosen the mesial root by inserting it into a
space between the lamia dura and the
surface of the root from the mesial and
distal surfaces until loosening of the root
occur . The other root could extracted by
using Winter or Cryer elevators
88. Removal of Broken Roots of
Maxillary Molars
• Maxillary molars roots may be removed by
grasping the palatal and the distobuccal roots
with the upper roots forceps or with Bayonet
Forceps .
• This procedure will either remove all three roots
or cause breaking of mesiobuccal root which
then can be removed by upper root forceps or
with Warwick James curved elevator inserted
into empty disto-buccal socket
89. Removal of Broken Roots of
Maxillary Molars
• Another technique is first
to separate the fused
roots with drill in the
form of “ Y “ shape and
then remove them
individually by mean of
forceps or by Warwick
James curved elevator
between the separated
roots.
90. … Take time to Love
It is the secret of
!eternal youth
92. Post-extraction care
• Inspection of the socket
• Removal of debris and any
tooth fragments
• Squeezing the socket
• Insuring haemostasis (Gauze
pack)
• Remove any septic granulation
tissue or granuloma from the
socket
• Trim and smooth any sharp
edges from the alveolar plate
of bone
• Clean the patient lips and face.
93. Post-extraction Instructions
1-Keep biting on gauze, sponges for about one
hour after extraction, by the time if bleeding is
controlled, discontinue pressure pack
2-No mouth wash for at least 24 hours after
extraction
3-Avoid any hot food or drink for the rest of the day
to prevent bleeding
4-The diet must be cold fluids or soft food to avoid
irritation of the wound
5-Avoid any hard labour and have an adequate
rest
97. Rules
• Palm grip
• Don’t use the neighbouring
tooth as a fulcrum
• Don’t use the buccal or lingual
plate of bone as a fulcrum
• Use the left hand for
reflection, guard and support
• Take care of the surrounding
vital structures
• Follow respectfully, root
curvature
98. Principles of Use of Elevator
• Wedge principle: straight elevator
• Lever principle: Copland elevator
• Axel and Wheel principle: Cryer’s elevator
99. Principles of Use of Elevator
Wedge Principle
Some elevators are designed primarily to
be used as a wedge e.g. Apexo,and
coupland. This elevators are forced
between the root of the tooth and the
investing bony tissue parallel to the long
axis of the tooth
100. Principles of Use of Elevator
Lever Principle:
On applying this principle the elevator is a
lever of the first class the position of the
fulcrum is between the effort and
resistance in order to obtain a mechanical
advantage in a lever of the first class the
effort arm on one side of the fulcrum, must
be longer than the resistance arm
101. Principles of Use of Elevator
Wheel and Axle Principle
The wheel and axle is a
simple machine the effort
is applied to the
circumference of a wheel
which turn the axle so as
to raise a weight. It could
be used as a sole work
principle in removing the
teeth, it is also used in
conjunction with a wedge
or lever principles
106. Dental Elevators Classification
• I-According to use:
1-Elevators designed to remove the entire
tooth, straight elevators, hospital pattern
and winter elevator
2-Elevators designed to remove roots
broken off at the gingival line e.g. Apexo
elevator , Coupland and lido lavien
elevators
3-Elevators designed to remove roots
broken off half way to the apex e.g. curved
elevator hospital pattern, winter elevator
and Apexo elevator
107. Dental Elevators Classification
• II-According to Form:
1-Straight all types
2-Curved right and left
3-angulated right and left
4-Cross bar “ handle at right angle to the
shank”
111. Choice of elevators
•
•
•
•
Remaining tooth structure
Space available
Availability and position of solid fulcrum
Direction of the required movement
112. Characteristics
• Has no joints
• Needs a fulcrum to
work
• Has to be wedged
between bone and
tooth
• Exerts less directional
force on the tooth
• Different sizes and
shapes
113. Indications of use
Breaking down the periodontal attachment
Luxation or removal of full tooth
Luxation and removal of remaining roots
Bone removal
Mucoperiosteal elevation
114. Danger in the Use of Elevators
1-Loosening or extracting the adjacent teeth
2-Fracture the alveolar process or fracturing the
mandible
3-Penetrating the maxillary antrum or forcing the
root into the antrum
4-Forcing a root a root of a mandibular molar
through lingual plate of the mandible
5-Damage of soft tissues by slipping of the tip of
the elevator
115. Point to remember in
extraction of teeth
Never refer to the extraction of tooth as a
“simple extraction”. You may find yourself
in the embarrassing position of trying to
explain to the patient why this simple
extraction taking so much time and effort
Anticipate breakage by knowing all reason
why root and crown break. Forewarn the
patient of the possibility of breakage or
fracture
