The document discusses mixed dentition analysis, which involves estimating space requirements for permanent teeth based on measurements of primary teeth. It describes three main methods: arch length discrepancy, Moyer's predictability tables, and radiographic analysis. Arch length discrepancy involves measuring the space available between molars and comparing to the summed widths of teeth in between. Moyer's tables provide predicted widths of unerupted canines and premolars based on measured primary tooth widths. Radiographic analysis uses dental casts and x-rays to directly measure unerupted tooth sizes and correct for magnification.

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.
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.

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.
3. MIXED DENTITION
The period in which both primary and permanent teeth are present
in the oral cavity.
Usually present between age 6 to 12 years.
when some of the primary teeth are being replaced by permanent
teeth,
starts with the eruption of the first permanent tooth.
4. Mixed Dentition Analysis
The Mixed Dentition Analysis helps to estimate
the amount of spacing or crowding which would
exist for the patient if all the primary teeth were
replaced by their successors.
5. Methods of space analysis in mixed
dentition
Arch Length Discrepancy
Moyers predictability table
Tanaka and Johnston
Radiographic method
6. Arch Length Discrepancy
Arch Length Discrepancy : is the difference
between the space available, generally
determined by the bony dental alveolus between
two per. Molars, and the space required which is
the sum of all mesiodistal tooth widths mesial to
1st molars.
7. SPACE AVAILABLLE
SPACE AVAILABLE: Is measured from mesial of one 1st
permanent Molar to the mesial of other 1st permanent
Molar.
Also called Arch perimeter
Measured by
1. Brass wire
2. Vernier Caliper
3. Divider
8. SPACE AVAILABLE
Divided into 4 quadrants
Measured from mesial of first permanent
molars to mesial of deciduous canine
From mesial of deciduous canine to midline
From midline to mesial of deciduous canine
From mesial of deciduous canine
to mesial of 1st molar
10. Space required : is the combine mesiodistal width of incisors canine
and premolars .
Each tooth is measured separately at its maximum width.
Measured with
1. Vernier caliper
2. Divider
12. Vernier caliper
To obtain the main scale reading look for the immediate
left of the zero on the Vernier scale. Here the main scale
reading is
1cm = 10mm
13. Vernier caliper
To obtain the Vernier scale reading look closely for
an alignment of the scale lines of the main scale and
Vernier scale, here the Vernier scale reading is 0.05cm
=0.5mm
Reading is 7.5 mm
14. Divider
Shouldn't be lose
Tip points should touch
Should be pointed
Placed parallel to the incisal edges
At maximum crown bulge/contact point
15. Space required in mixed dentition
Three methods to find out mesiodistal width of
unerupted canine and premolars
1. Tanaka and Johnston
2. Moyer’s predictability table
3. Radiographic
16. Tanaka and Johnston
Measure mesiodistal width of mandibular incisors
[Not maxillary as their sizes varies]
Sum the mesiodistal widths of mandibular incisors and divide by 2
For mandibular canine and premolars MD width add 10.5
For maxillary canine and premolars MD width add 11
17. If Mesiodistal width of lower incisors = 22
22/2=11
For lower premolars and canine add 10.5
11+10.5=21.5 (width of single side so multiply by 2)
21.5 x 2 =43 (MD width of canine premolars of both sides )
18. Add width of lower incisors and canine
43+22=65mm
SPACE REQUIRED in lower arch for incisors, canines and
premolars .
19. FOR MAXILLARY UNERUPTED CANINES AND
PREMOLARS:
Now here we will put the MD width of Mandibular incisors for
formula correction i.e. 22mm
22/2=11
ADD 11
11+11= 22mm [for one side]
FOR BOTH SIDES X 2 = 22X2 =44mm
20. For upper premolars and canines add 11
11+11 = 22 (width of single side so multiply by 2)
22x 2 =44 (MD width of canine premolars of both sides )
Sum both sides plus maxillary incisors value
44+ 38 =82 space required in maxillary arch
21. Moyer’s Methods
Measure the mesiodistal width of mandibular incisors (22)
See for the value of premolars and canine at 75% in the table
75% it is percentile
75% is standard set by American guidelines
22. HOW TO USE MOYERS table ?
Check whether it is maxilla or mandible
Male or female
FOR EXAMPLE
what is the value of a male’s lower cuspids & bicuspids on Moyer's
chart
if MD width of patients mandibular incisors
is 22m
MD width of unerupted canine or premolars of 1 side is 21.4 mm
23. For both sides
21.4 x 2 =42.8mm
42.8 + 22 = 64.8 mm (space required of lower canines and premolars
by moyer’s method)
24.
25.
26. Radiographic Method
[HUCKABA’S]
Dental cast and patient radiograph is required
Radiograph may be periapical or OPG
Reaquired Mesiodistal width of each tooth is measured separately
on the cast and radiograph.
Calculate with formula x = x’y/y’
27. X is unerupted tooth permanent
Y is erupted tooth on cast deciduous
X’ is unerupted tooth on radiograph permanent
Y’ is erupted deciduous tooth on radiograph
28. POINTS TO BE NOTED
BAR means something on the radiograph
We take Y’ to check the magnification
The formula given above is used to cancel the magnification in order to
get the actual value.
