INTRODUCTION
 Fibro-osseous lesions are diverse group of processes
that are characterized by replacement of normal bone
by fibrous tissue containing a newly formed
mineralized product.


CLASSIFICATIONS
 Pindborg and Kramer s classification
 Charles Waldron (1993)
 Brannon and fowler

 Slootweg and Muller (1996)


FIBROUS DYSPLASIA


FIBROUS DYSPLASIA
 Fibrous dysplasia is a benign lesion, presumably
developmental in nature, characterized by a presence
of fibrous connective tissue with a characteristic
whorled pattern and containing trabeculae of
immature bone. (W.H.O )
 Marx and Stern(2003)


TYPES
 Philip et al (1997) classified fibrous dysplasia into

1. Monostotic F.D
Juvenile

Juvenile, aggressive

Adult
2. Polyostotic F.D

Craniofacial type

Jaffe s type

Albright syndrome

CLINICAL FEATURES
 Monostotic type


CLINICAL FEATURES
 Polyostotic type


RADIOGRAPHIC APPEARANCES
 Depends upon the degree of lesions maturation
1.Radiolucent
2.Radiopaque
3.Mixed Radiolucent-Radiopaque


HISTOPATHOLOGY


DIFFERENTIAL DIAGNOSIS
 Ossifying fibroma
 Pagets disease
 Chronic osteomyelitis

 Osteosarcoma


TREATMENT
 Medical management


TREATMENT
 Surgical management


Surgical approach
Weber- Ferguson incision

Altemir incision / Lynch’s
modification


CEMENTO-OSSEOUS DYSPLASIA


TYPES
 Based on clinical & radiological features Periapical COD




Focal COD
Florid COD


PERIAPICAL COD
PCOD is defined by WHO classification as “a nonneoplatic lesion affecting the periapical lesions of one
or more teeth”

 CLINICAL FEATURES


Periapical COD
 Radiological features


Differential diagnosis
 Radiolucent lesions-

radicular cyst
odontogenic keratocyst
Radio-opaque lesions
odontoma
chronic osteomyelitis
osteoblastoma

FOCAL COD
 Clinical features


Differential diagnosis
 Odontoma
 Cementoblastoma
 Osteoblastoma

 Ossifying fibroma
 Condensing osteitis


FLORID COD


HISTOPATHOLOGY
 All the three exhibit similar features.
 The tissue consists of fragments of cellular

mesenchymal tissue composed of spindle shaped
fibroblasts and collagen fibres with numerous small
blood vessels and free hemorrhage.
 Within this background, a mixture of woven
bone, lamellar bone and cementum like material is
seen.
 With maturation the ratio of fibrous tissue
background to mineralized material decreases.

TREATMENT


OSSIFYING FIBROMA


Pindborg J.J11 (1965) defines ossifying fibroma as a
sharply demarcated, intraosseous benign tumour that
occurs in a single bone and shows gradual
transformation of a cell rich connective tissue in to bone


OSSIFYING FIBROMA


OSSIFYING FIBROMA
 Radiographic features


OSSIFYING FIBROMA
 Histopathology
The lesion consists of fibrous tissue that
exhibits varying degrees of cellularity and
contains mineralized material in the form
of trabeculae of osteoid, bone or
cementum.
The trabeculae vary in size and frequently
show a mixture of woven & lamellar
patterns, peripheral osteoid and
osteoblastic rimming, peripheral brush
borders that blend into adjacent bone.
Variation in the type of mineralized
material differentiates it from fibrous
dysplasia.

 Treatment and prognosis


JUVENILE OSSIFYING FIBROMA


 Radiographic features


 Histopathology


Miscillaneous lesions
 Osteoblastoma
 Osteiod osteoma
 cementoblastoma
