This document discusses the diagnosis and classification of periodontal disease, as well as factors that affect treatment options. It describes Glickman's four-grade classification system for periodontal disease and details treatment approaches for each grade. Surgical procedures like root resection, hemisection, and extraction are discussed as options for managing multi-rooted teeth with furcation involvement, depending on factors like root morphology, bone loss pattern, and oral hygiene. Maintaining a clean, maintainable architecture and preventing further attachment loss are the goals of treating furcation defects.

IOSR Journal of Dental and Medical Sciences is one of the speciality Journal in Dental Science and Medical Science published by International Organization of Scientific Research (IOSR). The Journal publishes papers of the highest scientific merit and widest possible scope work in all areas related to medical and dental science. The Journal welcome review articles, leading medical and clinical research articles, technical notes, case reports and others.
Overdentures are a useful treatment option in many clinical situations. A simple complete lower overdenture which encloses the roots of two root-treated canines has been shown above (Fig. 12.51). Cases can be more complicated than this. The reduction in the crowns of the teeth may have occurred due to tooth wear from a combination of erosion and attrition. In the elderly, where such tooth reduction has occurred, root canal treatment may not be necessary. The removal of the roots will not benefit the patient and the overdenture is the best form of treatment.
Less common situations, such as partial anodontia, cleft palate or loss of tooth crown substance in dentinogenesis imperfecta, may also require restoration using overdentures. The distinction between an onlay and an overdenture is not clear-cut and a potentially difficult partial denture treatment, such as the restoration of a free end saddle, may be helped by the coverage of a canine or molar tooth with a reduced crown rather than a more involved crown restoration.
In the case illustrated in Figure 12.53, an elderly patient has severe tooth surface loss. The aetiology of this wear must be diagnosed before treatment is commenced. For instance, is this wear a result of parafunction or erosion from the consumption of acidic drinks? The remaining dentition has been restored and a definitive overdenture placed.

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.

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
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.

This slides describes the basic concepts of ICT, basics of Email, Emerging Technology and Digital Initiatives in Education. This presentations aligns with the UGC Paper I syllabus.
2. ETIOLOGY
-- Bacterial plaque
-- Root trunk length
-- Root morphology
-- Cervical enamel projections
Local factors affect the rate of plaque deposition
or complicate the performance of oral hygiene
procedures and contributing to the development
of periodontitis and attachment loss
3. DIAGNOSIS
-- Careful probing
-- Transgingival probing
factors that contribute :
Morphology of the affected tooth
Position of tooth relative to adjacent teeth
Local anatomy of the alveolar bone
Configuration of any bony defects
Caries and pulpal necrosis
7. GRADE III
Facial and lingual bony plates are lost
Filled with soft tissue and not visible
Radiolucent in the furcation area
8. GRADE IV
Inter dental bone is destroyed
Soft tissue have receded apically
Furcation opening is clinically visible
Tunnel therefore exists between the roots
9. FACTORS AFFECTING TREATMENT
ROOT TRUNK LENGTH
ROOT LENGTH
ROOT FORM
INTER RADICULAR DIMENSION
ANATOMY OF FURCATION
CERVICAL ENAMEL PROJECTIONS
10. ROOT TRUNK LENGTH
Shorter the root trunk length – more accessible
to facilitate surgical procedures than the long
root trunks or fused roots
11. ROOT LENGTH
Teeth with long roots are more readily treated, as
sufficient attachment remains,to meet functional demands
13. INTER RADICULAR DIMENSION
Teeth with widely separated roots present
adequate instrumentation during scaling,
root planning, and surgery than closely
approximated or fused
roots
14. ANATOMY OF THE FURCATION
Bifurcation ridges
Concavity in the dome
Accessory canals
Complicates scaling, root planing and
surgical therapy and maintenance
15. CERVICAL ENAMEL PROJECTIONS
Prevalence is highest for mandibular and
maxillary second molars
AFFECT : plaque removal
COMPLICATE : scaling and root planning
They are removed to facilitate maintenance
17. THE ANATOMY OF BONY LESIONS
PATTERN OF ATTACHMENT LOSS
Horizontal bone loss can expose the
furcation as thin facial/lingual plates of bone
The pattern of bone loss on other surfaces
of the affected tooth and adjacent teeth must
be considered during treatment planning
Molars with advanced attachment loss on only
one root may be treated by resective procedures
18. OTHER DENTAL FINDINGS
The combination of furcation involvement and
root approximation with an adjacent tooth may
dictate the removal of the most severely
affected tooth or the removal of a root
21. CLASS II
Flap procedures -- osteoplasty / odontoplasty
This reduces the dome of the furcation
and alters gingival contours to facilitate the
patients plaque removal
22. CLASS III / IV
Periodontal surgery
Endodontics
Replacement of tooth
24. SURGICAL THERAPY
ROOT RESECTION
INDICATED
Multi rooted teeth with grade II to IV furcation
Teeth serving as abutments of fixed or
removable restorations
Teeth that have sufficient attachment
remaining for function
25. Teeth with furcation defects that have been
treated successfully with endodontics but now
present with a vertical root fracture
Patients with good oral hygiene and low
activity for caries
27. WHICH ROOT TO REMOVE AND WHY ?
Remove the roots that will eliminate the
furcation and allow the production of a
maintainable architecture on the remaining roots
Remove the root with the greatest amount of
bone and attachment loss
28. Remove the root that best contributes to the
elimination of periodontal problems on
adjacent teeth
Remove the root with the greatest number
of anatomic problems such as severe curvature,
developmental grooves or accessory root canals
29. HEMISECTION
Splitting of two-rooted into two separate
portions
Also called as bicuspidization
INDICATED
Mandibular molars with buccal and lingual
class II or III furcations
CONTRAINDICATED
Molars with advanced bone loss in the
inter proximal and inter radicular zones
30. RESECTION / HEMISECTION PROCEDURE
Most commonly – disto-buccal root of the
maxillary first molar
Local anesthesia given
Full thickness flap is raised
Both facial and lingual / palatal flap raised
to provide better visibility and instrumentation
31. Debridement
A cut is then directed from just apical to
the contact point of the tooth through the
tooth to the facial and distal orifices of
the furcation
A high speed surgical length fissure or
cross-cut fissure carbine bur is used
32. For hemisection a vertically oriented cut is
made facio-lingually through the buccal and
lingual developmental grooves of the tooth
through the pulp chamber and through the
furcation
After sectioning the root is elevated from its
socket
Care should be taken not to traumatize bone
on the remaining roots or to damage an
adjacent tooth
33. Odontoplasty is performed to remove portions
of the developmental ridges and prepare a
furcation that is free of any deformity
Flaps are then approximated to cover any
grafted tissues or to slightly cover the bony
margins around the tooth
Sutures are then placed to maintain the
position of the flaps
The removal of a root alters the distribution
of occlusal forces on the remaining roots
Adjust the occlusion
38. EXTRACTION
Extraction of teeth with through and through
furcation defects [class III and IV ] and advanced
attachment loss is most appropriate therapy
for some patients
39. PROGNOSIS
The keys of long-term success :
Thorough and careful diagnosis
Selection of patient with good oral hygiene
Careful surgical and restorative management
