This document discusses fluorides in dentistry. It describes the sources of fluoride, mechanisms of how fluoride prevents tooth decay, and methods of fluoride delivery topically and systemically. It also addresses the indications for topical fluoride use, recommended dosages of fluoride tablets/drops, and potential toxicities like dental and skeletal fluorosis from inadequate or excessive fluoride intake. When used appropriately, fluoride is an effective cariostatic agent for improving dental health.

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.

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.

Acetabularia Information For Class 9 .docxvaibhavrinwa19
Acetabularia acetabulum is a single-celled green alga that in its vegetative state is morphologically differentiated into a basal rhizoid and an axially elongated stalk, which bears whorls of branching hairs. The single diploid nucleus resides in the rhizoid.

Conclusion.
3. INTRODUCTION
The cariostatic efficacy of fluorides has been
convincingly demonstrated and the recent
decline in caries prevalence is primarily
attributed to the increased use of fluoride
agents.
4. composition
Fluoride may occurs in combined form in a wide
variety of minerals.
Fluorspar[fluorite CaF2]- 49%
Fluorapatite[Ca10F2(PO4)6]- 3.4%
Cryolite[Na3ALF6]- 54%
5. SOURCES OF FLUORIDE
It is estimated that the intake of from fish by populations where fish
represents a significant portion of the diet is about 0.5mg/day.
Jawar,banana,potatoes also contain substatial quantities of fluoride.
Certain plants,such as taro,yams,and cassava,have been found to contain
relatively high fluoride levels.
Fluoride content of rock salt ranges between 40 and 200ppm.
The dried tea leaves contain 100-400 ppm fluoride.
Mineral water usually contains considerably higher concentration,from 1.5-

7. Mechanism of action of fluoride
The benefits of fluoride in the reduction of dental caries
have been known for years,but its exact mechanism of action
is not completely understood.
The mechanisms by which fluoride increases caries resistance
may arise from both systemic and topical application of
fluoride.
1. increases enamel resistance or reduction in enamel
solubility.
2. increases rate of posteruptive maturation.
3. remineralization of incipient lesions.
4. Interference with plaque microorganisms.
5. modification in tooth morphology.

10. Fluoride delivery methods
1. topical fluoride are placed directly on the teeth.
Topically applied fluoride is used to describe those delivery
system which provide fluoride for a local chemical reaction to
exposed surfaces of the erupted dentition.
The delivery system includes containing prophylactic
pastes,solutions,gels and varnishes as well as systems
designed for unsupervised home use,such as fluoride
dentifrices and rinses.
11. Indications for topical fluoride use
1.caries- active individual
2.children shortly after periods of tooth eruption,especially
those who are not caries free.
3.Those who take medication that decreases salivary flow or
have received radiation to head and neck.
4.after periodontal surgery when roots of teeth have been
exposed.
5.patients with fixed or removable prosthesis and after
placement or replacement of restoration.
6.patient with eating disorder.
7.mentally and physically challenged individuals.
12. Fluoride tablets/drops/lozenges:-
Fluoride tablets/drops/lozenges may be prescribed to individual patient or may be
part of a school or home based public health preventive dentistry program.
Fluoride compound used:-
Sodium fluoride is most commonly used.
The other compound used are acidulated phosphate fluoride,potassium fluoride or
calcium fluoride.
Supplements contains a measured amount of fluoride typically 0.25mg,0.5mg or
1.0mg.
13. Fluoride drops are dispensed with a measured dropper and are convenient for
infants.
Tablets and lozenges should be chewed, swished and swallowed.

15. Frequency of use and dosage:-
The council on dental therapeutic of the dosage schedule for dietary supplement
as shown in the table:-
16. Toxicity of fluorides
Fluorides is often called as a double-edges sword as an expression for anything
that can simultaneously help and hinder.
This is because inadequate ingestion of fluoride is associated with dental caries and
an excessive intake of fluoride can lead to dental and skeletal fluorosis.
ACUTE TOXICITY OF FLUORIDES:-
Acute fluoride toxicity results from rapid excessive ingestion of fluoride at one
time.
The speed and severity of the response are dependent on the amount of fluoride
ingested and the weight and age of the individual.
17. The most frequently encountered adverse effect to topical fluoride encountered
adverse effect of topical fluoride therapy is nausea.
This is caused by fluoride combining with hydrogen in the gastric juices to form
hydrofluoric acid a stomach irritant.
Other symptoms of fluoride toxicity include…
1.abdominal cramps.
2.vomiting
3.diarrhea
4.increased salivation
5.dehydration and thirst.
18. CHRONIC FLUORIDE TOXICITY
Chronic fluoride toxicity results from long term ingestion of small amounts of
fluoride.
The effect of chronic fluoride toxicity on enamel is dental fluorosis.
other problem such as skeletal fluorosis may occurs.
effect dosages duration
Dental fluorosis >2 times optimal Until 5 years
Skeletal fluorosis 10-25 mg/day 10-20 years
19. DENTAL FLUOROSIS
Dental fluorosis is caused by excessive intake of fluoride during tooth development.
Ingestion of water with a fluoride concentration two or three times greater than the
recommended amount causes white flecks and chalky opaque areas on the tooth
enamel.
Consumption of water containing four times the recommended amount of fluoride
causes a brown pitted corroded appearance on the enamel surface.
However although these teeth represent cosmetic problems they are highly to carious
attack.
20. CONCLUSION
When used appropriately, fluoride is s safe and effective
agent that can be used to prevent and control dental caries.
Fluoride has contributed profoundly to the improved dental
health of persons all over the world.
Fluoride is needed regularly throughout life to protect teeth
against tooth decay.
To ensure additional gains in oral health,water fluoridation
should be extended to additional communities and fluoride
toothpaste should be used widely.
