Local factors that can influence tooth eruption include infection, supernumerary teeth, gingival fibromatosis, and ankylosed teeth. Ankylosed teeth become fused to the bone, preventing normal eruption. Diagnosis involves tapping teeth and examining radiographs. Problems associated with ankylosed primary teeth include prevented exfoliation and delayed eruption of permanent teeth. Management may involve surgical removal, space maintenance, or watchful waiting depending on the situation. Ankylosed permanent teeth can also impact eruption and require techniques like luxation or surgery to encourage proper positioning.
Dentin dysplasia (DD) is a rare hereditary disturbance is inherited as an autosomal dominant trait.
unknown etiology that affects approximately 1 :100,000.
In 1972, Witkop classified it into type I and type II which affect both dentitions.DD Type I
Radicular dentin dysplasia
Characterized by:-
1.Both dentitions are affected.
2.Normal appearing crowns
3.No or only rudimentary root development (rootless teeth)
4.Incomplete or total obliteration of the pulp chamber.
5.Teeth may exhibit extreme mobility and exfoliate prematurely.DD type II
coronal dentin dysplasia
Characterized by:-
1.partial pulpal obliteration.
2.Thistle-tube-or flame-shaped coronal pulp chambers
3. Thread-like root canals
4. Usually the absence of periapical radiolucencies.
5. In this type of anomaly, teeth roots are of normal shape and contour.The enamel and the immediately subjacent dentin appear normal.
Deeper layers of dentin show an atypical tubular pattern with an amorphous, atubular area, and irregular organization.
Normal dentinal tubule formation appears to have been blocked so that new dentine forms around obstacles and takes on the characteristic appearances described as “lava flowing around boulders”The radiograph revealed features of dentine dysplasia type I with normal appearance of crown but no root development Autosomal Dominant Disorder:
Manifested in heterozygous states
At least one parent of index case is usually affected
Both males and females are affected.
Clinical feature can be modified by variation in penetrance and expressivity. Some individual inherit the mutant gene but are phenotpically normal. This is reffered to as “incomplete penetrance”.
In many condition the age of onset is delayed.
Inheritance Pattern:
Typical pattern is a heterozygous affected parent with a homozygous unaffected parent.
Every child has one chance in two of having the disease
Both sexes are affected equally..Autosomal Recessive Disorder
Largest category of Mendelian disorder
Usually does not affect the parent of the affected individual, but sibling may show the disease.
Complete penetrance is common.
Onset is frequently early in life.
Usually affect enzymatic proteins.
Pattern Of Inheritance:
Typical pattern is two heterozygous unaffected (carrier) parent.
The triat does not usually affect the parent, but siblings may show the disease
Siblings have one chance in four of being affected
Both sexes affected equally.

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.

June 3, 2024 Anti-Semitism Letter Sent to MIT President Kornbluth and MIT Cor...Levi Shapiro
Letter from the Congress of the United States regarding Anti-Semitism sent June 3rd to MIT President Sally Kornbluth, MIT Corp Chair, Mark Gorenberg
Dear Dr. Kornbluth and Mr. Gorenberg,
The US House of Representatives is deeply concerned by ongoing and pervasive acts of antisemitic
harassment and intimidation at the Massachusetts Institute of Technology (MIT). Failing to act decisively to ensure a safe learning environment for all students would be a grave dereliction of your responsibilities as President of MIT and Chair of the MIT Corporation.
This Congress will not stand idly by and allow an environment hostile to Jewish students to persist. The House believes that your institution is in violation of Title VI of the Civil Rights Act, and the inability or
unwillingness to rectify this violation through action requires accountability.
Postsecondary education is a unique opportunity for students to learn and have their ideas and beliefs challenged. However, universities receiving hundreds of millions of federal funds annually have denied
students that opportunity and have been hijacked to become venues for the promotion of terrorism, antisemitic harassment and intimidation, unlawful encampments, and in some cases, assaults and riots.
The House of Representatives will not countenance the use of federal funds to indoctrinate students into hateful, antisemitic, anti-American supporters of terrorism. Investigations into campus antisemitism by the Committee on Education and the Workforce and the Committee on Ways and Means have been expanded into a Congress-wide probe across all relevant jurisdictions to address this national crisis. The undersigned Committees will conduct oversight into the use of federal funds at MIT and its learning environment under authorities granted to each Committee.
• The Committee on Education and the Workforce has been investigating your institution since December 7, 2023. The Committee has broad jurisdiction over postsecondary education, including its compliance with Title VI of the Civil Rights Act, campus safety concerns over disruptions to the learning environment, and the awarding of federal student aid under the Higher Education Act.
• The Committee on Oversight and Accountability is investigating the sources of funding and other support flowing to groups espousing pro-Hamas propaganda and engaged in antisemitic harassment and intimidation of students. The Committee on Oversight and Accountability is the principal oversight committee of the US House of Representatives and has broad authority to investigate “any matter” at “any time” under House Rule X.
• The Committee on Ways and Means has been investigating several universities since November 15, 2023, when the Committee held a hearing entitled From Ivory Towers to Dark Corners: Investigating the Nexus Between Antisemitism, Tax-Exempt Universities, and Terror Financing. The Committee followed the hearing with letters to those institutions on January 10, 202

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.

Local factors affect tooth eruption
1. LOCAL FACTORS THAT
INFLUENCE ERUPTION
Presented by:
Dr. Shady A. M. Negm
Bachelor's Degree of Dental Surgery,
School of Dentistry, Pharos University.
1
2. 1. Infection:-
• Near the eruption time
cause early eruption
“soft tissue tearing,
bone resorption”
• Before long period
cause late eruption
“healing and fibrosis”.
2
4. 3. Gingival fibromatosis:
Very hard tissue of the gum.
It prevents eruption.
It is hereditary condition, treated by
gingivectomy
4
5. • 4. Ankylosed teeth:
It is a dental situation
in which the roots of
the tooth lose their
normal attachment to
the bone (small
ligament) and
become directly fused
to the bone.
5
7. • 1- The diagnosis of an ankylosed tooth is not
difficult to make. Ankylosis can be partially
confirmed by tapping the suspected tooth and
an adjacent normal tooth with a blunt instrument
and comparing the sounds. The ankylosed tooth
will have a solid sound, whereas the normal
tooth will have a cushioned sound because it
has an intact periodontal membrane that
absorbs some of the shock of the blow.
7
8. • 2- The radiograph is often a valuable aid
in making a diagnosis. A break in the
continuity of the periodontal membrane
indicating an area of ankylosis is often
evident radiographically.
8
15. • Extensive bony ankylosis of the primary tooth
may prevent normal exfoliation, as well as the
eruption of the permanent successor.
• The mandibular primary molars are the teeth
most often observed to be ankylosed.
Ankylosis involved second molar may be
indication of agenesis of succedanous tooth.
15
17. • 1- The cause of ankylosis in the primary
molar areas is unknown.
2- The observation of ankylosis in several
members of the same family lends support
to the theory that it follows a familial
pattern.
3- Very slow root resorption was observed
for most of the ankylosed teeth.
17
19. • 1- In the management of an ankylosed tooth,
early recognition and diagnosis are extremely
important.
2- The eventual treatment may involve surgical
removal and place space maintainer.
3- However, unless a caries problem is unusual
or loss of arch length is evident, the dentist may
choose to keep the tooth under observation or
build up occlusal surface.
4- A tooth that is definitely ankylosed may at
some future time undergoes root resorption and
be normally exfoliated.
19
20. • 5- When patient cooperation is good and
recall periods are regular, a watchful
waiting approach is best.
6- In situations in which permanent
successors of ankylosed primary molars
are missing, attempts have been made to
establish functional occlusion using
stainless steel crowns, overlays, or
bonded composite resins on the affected
primary molars. This treatment is
successful only if maximum eruption of
permanent teeth in the arch has occurred.
20
21. • 7- If adjacent teeth are still in a state
of active eruption, they will soon
bypass the ankylosed tooth.
21
23. • The incomplete eruption of a permanent
molar may be related to a small area of
root ankylosis. If the permanent tooth is
exposed in the oral cavity and at a lower
occlusal plane than the adjacent teeth,
ankylosis is the probable cause.
23
25. • 1- Familial.
2- Unerupted permanent teeth may
become ankylosed by inostosis of enamel.
The process follows the irritation of the
follicular or periodontal tissue resulting
from chronic infection.
25
27. • 1- The removal of soft tissue and bone
covering the occlusal aspect of the crown
should be attempted first, and the area
should be packed with surgical cement to
provide a pathway for the developing
permanent tooth.
2- Luxation technique effective in breaking
the bony ankylosis.
27
28. • 3- If the rocking technique is not
immediately successful, it should be
repeated in 6 months. A delay in treatment
may result in a permanently ankylosed
molar.
4- Surgery exposure + orthodontics
traction + RCT.
