Fibrous dysplasia is a fibro-osseous lesion of the jaw which runs a chronic course. It has been well explained in the literature through high-quality 2D clinical, radiographic, and histopathological images. But the clinicians and most of the times students too, don't understand the histopathological aspect of fibrous dysplasia through the description of text and existing 2D images. This article is preliminary attempt to explain the key events of histopathological aspects of fibrous dysplasia in third dimension in a life-like manner through 3D images and video which author herself has designed, for better understanding not only by oral and general pathologists, and students but also by patients, which is the unique feature of this manuscript. Preliminary 3D images and videos on histopathological aspect of fibrous dysplasia were designed by using 3Dmax (Autodesk Media and Entertainment) and Adobe premiere pro 5.5 software which is a video editing software (Adobe Systems). Internal cellular environment of a lesion has been created in a life-like manner through 3D animation video. Histopathological aspect of all oral lesions should be explained in this manner for better understanding.

| Introduction|| |
Fibrous dysplasia is an intraosseous bony lesion and most of the times recur. It is very common lesion to be discussed in academics in dental and medical literature and is familiar lesion among the clinicians too. It has been well explained in dental literature through high-quality 2D images. However, readers cannot visualize its pathogenesis and histopathology through such description in a life-like manner because the description has always been of a slice of the biopsy. Histopathological aspects of all the lesions in the literature have been explained, only with the help of 2D images. Therefore, author has designed 3D images and video to recreate life-like tissue and to explain the key events of its etiopathogenesis and histopathology, to be clearly understood not only by dental and medical experts and students but also by patients.,, Only few diseases have been explained in dental literature with the help of 3D images and video so far.,,,,
| Methodology|| |
Preliminary 3D images and videos [Video 1] on histopathological aspect of fibrous dysplasia were designed by using 3Dmax (Autodesk Media and Entertainment) and Adobe premiere pro 5.5 software which is a video editing software (Adobe Systems).
Ethical approval was not considered as this manuscript is not patients based original research. Instead it's an original article based on 3D animation and 3D images on histopathological aspect of fibrous dysplasia using various softwares which has never been reported yet.
Histopathological of fibrous dysplasia in 2 dimensions
Biopsy tissue shows numerous irregular, C-shaped trabeculae of woven bone, not connected to each other, showing no relation to functional patterns, in a background of low to moderate cellular fibrous connective tissue. Early lesions show more of fibrous tissue whereas advanced lesions show more of bony trabeculae imparting the characteristic “Chinese letter pattern.” The intervening fibrous connective tissue shows mononuclear cells resembling fibroblasts and progenitor osteoblasts.
Key events in the pathogenesis of fibrous dysplasia in the third dimension
- Resorption of existing spongy bone - The spongy bone has been shown as interconnected rods present between the two cortical plates. Resorption process has been shown as disappearance of trabecular bone [Figure 1] and [Figure 2]
- Spongy bone is replaced by highly cellular stroma - The resorbed spongy bone is then replaced by highly cellular fibrous stroma which has been shown as cell-rich tissue with plump-shaped fibroblasts [Figure 3]
- Formation of immature bone - These young fibroblasts then lay down immature bone which is curvilinear. All the bony spicules are equidistant from each other. It gives typical Chinese script pattern [Figure 4].
- Due to the proliferation of the lesion, the cortical plate shows expansion. All the above events have been put together in a 3D animation video https://drive.google.com/file/d/16F_HXwHTqcgdjbbvxOssgruYMpN1Y3P_/view?usp=sharing [Video 1].

3D animation videos on histopathological aspects of all lesions should be made available on multimedia for better understanding for students in a life-like manner and to discontinue the trend of rote learning among the students.
The authors would like to thank Mr. Harishankar Agnihotri and late Mr. Bhavesh, faculties of “Maya Academy of Advanced Cinematics (MAAC)” Mulund West, Mumbai, Maharashtra, for teaching various software to author (Dr. Sandhya Tamgadge).
