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.

CLINICOPATHOLOGICAL FEATURES OF PERIPHERAL OSSIFYING FIBROMA IN A SERIES OF 4...ishita1994
Peripheral ossifying fibromas are benign mesenchymal lesions that usually arise in the anterior maxilla of young female patients. Histologically they consist of spindle cell proliferation with focal mineralization. We reviewed 48 specimens from 41 patients and recorded the clinical data, sex, and age of the patients, site, and size of the lesions, treatment, and postoperative outcome. Histologically the presence of mature, woven bone, cementum, and calcifications was evaluated and evaluated immunohistochemically. Lesions were more frequent in female patients in the third and fourth decade and were usually in the lower maxilla and smaller than 2 cm. All lesions were conservatively excised, and they relapsed in eight patients. Histopathologically, the lesions were poorly circumscribed, with moderately cellular proliferation, and with no discernible architectural pattern. All tumors showed some degree of mineralization, the presence of immature bone being the most common. Immunohistochemical examination showed staining of tumoral cells for smooth muscle actin and CD68. Lesions tended to occur more commonly in female patients, but one decade later than usually reported. We found a higher recurrence rate in lesions that contained cementum-like material but without bone formation, suggesting a lack of maturation in this group. Immunohistochemical results were consistent with myofibroblastic differentiation but they added no information about the behavior of the lesions.

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”.
Unit 8 - Information and Communication Technology (Paper I).pdfThiyagu K
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.
This is a presentation by Dada Robert in a Your Skill Boost masterclass organised by the Excellence Foundation for South Sudan (EFSS) on Saturday, the 25th and Sunday, the 26th of May 2024.
He discussed the concept of quality improvement, emphasizing its applicability to various aspects of life, including personal, project, and program improvements. He defined quality as doing the right thing at the right time in the right way to achieve the best possible results and discussed the concept of the "gap" between what we know and what we do, and how this gap represents the areas we need to improve. He explained the scientific approach to quality improvement, which involves systematic performance analysis, testing and learning, and implementing change ideas. He also highlighted the importance of client focus and a team approach to quality improvement.

ANGIOLEIOMYOMA WAS COMFIRMEDwww.indiandentalacademy.com
25. DISCUSSION
• Leiomyoma is a benign smooth muscle tumor
that may appear in any location of the body.
• VIRCHOW IN 1854.
LEIOS – SMOOTH
MUV - MUSCLE
OMA - TUMOR
• It most commonly occurs in the uterus and in
gastrointestinal tract.
• It occurs rarely in the orofacial region
www.indiandentalacademy.com
26. Incidence – 95% in uterus
- 4-5% in GIT and skin
- 0.065% in oral cavity
( due to the scarcity of the smooth muscle)
GENDER – More common in female ( 2:1)
25% of woman have noticeable fibroids in
their reproductive period.
www.indiandentalacademy.com
27. CLASSIFICATION
• WHO HISTOLOGICALLY CLASSIFIED IN
TO 3 TYPES
1. Leiomyoma ( Solid)
2. Angiomyoma (Vascular leiomyoma)
3. Leiomyoblastoma ( Epithelial leiomyoma)
www.indiandentalacademy.com
28. • Solid leiomyoma – These are well delimited
tumor not associated to the vascular smooth
muscles.
They consists of a network of fusiform cells with
a variable presence of collagen.
• Angioleiomyoma – It arises from vascular
smooth muscles.
• Leiomyoblastoma – It consists of round or
polygonal cells with clear areas surrounding the
nucleus and an acidophillic cytoplasm.
www.indiandentalacademy.com
29. • BASED ON ANATOMIC SITE AND
ORIGIN OF SMOOTH MUSCLE
1. Piloleiomyoma
2. Angioleiomyoma
3. Genital leiomyoma
In piloleiomyoma – Multiple piloleiomyoma
- Solitary piloleiomyoma
www.indiandentalacademy.com
30. PATHOPHYSIOLOGY
• PILOLEIOMYOMA – It may arises either
solitary or multiple lesions, At times
numbering in thousands.
• It arises from the arrector pili muscle ,
which attaches proximally to the hair
follicle and distally to the multiple
attachment points with in the papillary and
reticular dermis as well as to the
basement membrane.
www.indiandentalacademy.com
31. PILOLEIOMYOMA
AGE - Multiple type – 10 to 30 yrs
Solitary type - usually appears later
SEX - Men and Women are equally affected
www.indiandentalacademy.com
32. Clinical features
• The most common feature is pain .
Pain can be spontaneous or induced by cold
or tactile stimuli.
Multiple piloleiomyomas can occur on
Face
Trunk
Extremities with various distribution pattern
www.indiandentalacademy.com
34. • Solitary piloleiomyoma is usually found on
lower extremity.
• They are fixed in the skin but they can be
easily moved over the deeper
subcutaneous tissue.
• Individual lesion appear as smooth ,firm
papule or nodule with reddish brown color.
• They are usually smaller than 2cm in
diameter.
www.indiandentalacademy.com
35. HISTOLOGIC FEATURES
• They occur mainly in the reticular dermis
and are non encapsulated.
• The smooth muscle bundles are interlaced
with the variable amount of collagen .
• Occasionally , very low mitotic activity may
be noticed.
www.indiandentalacademy.com
38. • According to Duhig and Ayer, the vascular
leiomyoma represents only a stage with in a
continuous maturation process of smooth
muscle fibers.
• The maturation process sequence would be as
hemangioma, vascular leiomyoma and to solid
leiomyoma.
• But according to Damm and Neville,
Solid leiomyoma is histologically different from
angioleiomyoma, hence two entities should be
regarded separately.
www.indiandentalacademy.com
39. • These appear as solitary well defined skin
coloured nodules located fairly deep in the
dermis and are frequently smaller than 4
cm.
• Pain is not a prominent feature.
• About 60% of the angiomyomas are
symptomatic.
• Pain in the angiomyoma may be due to
nerve fibers in the stroma or in the wall or
due to the contraction of the muscle fibers.www.indiandentalacademy.com
40. RADIOGRAPHIC FINDINGS
• Angiomyoma shows charateristic findings
on ultrasound and on MRI.
• On ultrasound images , angioleiomyoma
shows well defined margins and a
homogenous structure suggestive of their
benign nature.
• On colour doppler it shows high resistance
in intratumor arteries suggesting the
presence of muscular arteries.
www.indiandentalacademy.com
42. • On MRI, they show the mixed
hyperintense and isointense areas
compared with the skeletal muscle.
• Capsule appears as hypointense area in
T2 weighted images.
www.indiandentalacademy.com
43. HISTOLOGIC FEATURES
• Well circumscribed and encapsulated
tumor is usually noted in the lower dermis.
• There are interlacing bundles of the
smooth muscle fibers between the
vascular channels .
• Perinuclear vacuolization may be
appreciated in cross section of the muscle
fibers
www.indiandentalacademy.com
44. • The vessel walls display the layers of smooth
muscle fibers and they merge peripherally into
the intervascular muscle fibers.
• The lumen of the vessels may be slit like or
dilated.
• In long standing cases, degenerative changes
like vascular thrombosis, stromal hyalinization,
myxoid changes, dystrophic calcification and
nuclear atypia may present
www.indiandentalacademy.com
46. GENITAL LEIOMYOMA
• It appears as asymptomatic solitary lesion
arising from the dartoic, valuar, or
mamillary muscles in the genital region or
on the nipple.
• Compare to other two types , it has very
low incidence.
• Histologically, it is similar to the
piloleiomyoma.
www.indiandentalacademy.com
47. ORAL LEIOMYOMA
• The leiomyomas are infrequent in the oral cavity.
• They arise from the smooth muscles of the
tunica media or by the embryonic remnants
such as lingual duct or circumvallate papilla.
• The overall incidence of the oral leiomyoma is
0.065%
• They commonly occur in adults.
• males are more frequently affected than females
• The most frequent locations are lip, tongue, hard
and soft palate and cheek.
www.indiandentalacademy.com
48. • The most common type is Angioleiomyoma (60-
69%)
Solid leiomyoma (30%)
Leiomyoblastoma (1.3%)
• They appears as the smooth surfaced
submucosal nodule.
• The colour of the lesion depends upon their
vascularization and depth.
• The 55% of the cases will appear as red, blue,
purple in colour.
www.indiandentalacademy.com
49. • Usually the oral leiomyomas are
asymptomatic.
• Depending upon their size and location,
there may be toothache, loose tooth,
deglutition difficulty, shortness of breath,
referred pain in TMJ etc.
