A Strategic Approach: GenAI in EducationPeter 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 maximum pressure is called systolic
The minimum pressure is diastolic.

Diastolic.
Blood pressure is influenced by
Cardiac output.
Blood volume.
Viscosity of the blood.
Condition of blood vessels.(especially arterioles)
Heart rate.
12. www.indiandentalacademy.com
There are two methods of determining
blood pressure.
Direct

inflatable bag covered by a cuff and
monometer to register the force and rate

Technique.
Patient is seated comfortably.
Inflatable bag is positioned over the bare upper arm at
the level of the patients heart,with the patients palm
supine.
The brachial or radial artery is palpated and the bag is
inflated to obliterate the vessel,about 30mm Hg above
the estimated systolic pressure.
The cuff is deflated 2 to 4 mm Hg at every heartbeat.
Using a stethoscope over the brachial artery, the
systolic pressure is recorded at the first tapping sound
heard.
When the sounds become muffled or inaudible the
diastolic pressure is noted.

Mainly coumarin derivatives(coumadin).
Usually due to recent myocardial infarction,

Normal range is 12-14 seconds.
Recently the international normalized
ratio(INR) is used to asses bleeding and
anticoagulation potentials.
2.0 INR are acceptable for routine treatment.

There are several studies now that support the
continuation of anticoagulant therapy during
surgery.
Others studies support the reduction of
anticoagulant to bring PT to a normal value.
ADA guidelines states that patients on
anticoagulant therapy can even undergo
surgical procedures.
Still majority of physician surveyed
recommend anticoagulant alteration for a

Anemia.
It is the most common hematologic disorder.
It is not a disease entity; rather it is a symptom
complex that results from a
decreased production of erythrocytes,
an increased rate of their destruction.
Deficiency of iron.
It is defined as a reduction on the oxygen-
carrying capacity of the blood and results from
a decrease in the number of erythrocytes or
abnormality of hemoglobin.

Denture is less secure and patient may
not be able to follow the good diet.
159. www.indiandentalacademy.com
Osteeoporotic changes in the jaws are
similar to other bones in the body.
The structure of bone is normal; however due
to uncoupling of the bone
resorption/formation process with emphasis
on resorption,
the cortical plates become thinner,
the trabecular bone pattern more discrete,
and advanced demineralization occurs.
Bone mass Men woman

Prosthetic joints.
Literature reports there is association between
prosthetic joint infection and dental treatment.
It is hypothesized that bacteria from the dental
treatment may seed the prosthesis and
produce infection.
The joint ADA – AAOS( American academy of orthopedic
surgeons) advisory statement recommends
- the aggressive treatment of
acute orofacial infections in patients with total
joint prosthesis because those bacteremias
associated with acute infections can and do
cause late implant infections.

Osteoradionecrosis is a condition
characterized by the development of non vital
areas of osseous tissue in irradiated bone after
injury.
Treatment
Disease should be best prevented whenever
possible.
Segmental resection and extensive reconstruction.
It is extremely costly both in time and resources.
188. www.indiandentalacademy.com
Potential implant patient.
The fields irradiated and the dosages
received by the tissues in that area must be
analyzed to determine areas of the jaws at
risk.
If areas receiving radiation doses of 60 Gy
must be violated surgically,preoperative
hyperbaric oxygen therapy(HBO) can reduce
the risk of Osteoradionecrosis.

Chemotherapy
Drugs used as chemotherapeutic
agents have the capability to disrupt
normal cellular events leading to
replication.
Oral mucosal ulcerations are common
and often complicate therapy by

Granulocyte-stimulating factor
Granulocyte-macrophage colony-stimulating factor
Can be used in patients exhibiting severe
neutropenia.
The clinician managing the oral needs of the
patients with cancer must weigh the risks of
infection and failure inpatients undergoing or
likely to require chemotherapy against the
benefits of dental rehabilitation.

Reasons for treatment.

Psychological problems.
Patients with problems of Psychogenic origin
may become convinced that provision of a
stable dental occlusion will cure their
problems.
Kiyak et al (1990) reported a correlation
between high scores of neuroticism and less
satisfaction with treatment results.
Such patients should not be denied treatment
but require more supportive therapy
