Temporomandibular joint (TMJ) is one of the most intricate and complicated loading joints found in humans. TMJ is also called the mandibular joint; it is an ellipsoid variety of the left and right synovial joints which form a bicondylar articulation. The components of this joint are a fibrous capsule, a disk, synovial membrane, fluid, and tough adjacent ligaments. The mandible and the cranium are mechanically two different components; therefore, the appropriate term for this joint is the craniomandibular articulation. It is not possible to understand the accurate points of occlusion without a thorough knowledge of the biomechanics, physiology, and anatomy of TMJ. The primary necessity for successful occlusal treatment is steady and comfortable TMJ. This understanding of the TMJ is the foundation to diagnosis and treatment of almost everything a dentist does.
Objective: The purpose of this study is to identify a co-relation between clinical and histopathological features of verrucous carcinoma. Materials and Methods: This study was conducted based on Knowledge Attitude and Practice (KAP) questionnaire comprising of 3 sets of questions covering clinical and histopathological aspects of the oral verrucous carcinoma. The target subjects were specialists in the field of Oral Medicine and Radiology, Oral and Maxillofacial Surgery and Oral Pathology. Results and Conclusion: Verrucous carcinoma is a low grade variant of squamous cell carcinoma and the clinical features of both are very similar. The treatment of both differs widely; we fail to diagnose it correctly. This study correlates the clinic-pathologic features of oral verrucous carcinoma by means of statistically analyzing the varied clinical features and pathological impressions. This is helpful in eliminating the diagnostic dilemma and thus channelizing the data to present a clear treatment planning.
To achieve a successful prosthesis, it is important to achieve harmony between the maxillomandibular relationships. This does not pertain only to the opening or closing but is a complex relationship which exists in three dimensions. Hence, it is very important to record this relationship with the least possible error to obtain a successful prosthesis. To record this maxillomandibular relationship, numerous materials are in use and what matters are the precision of the recording materials and their stability. This article seeks to present a review of major bite registration materials and their modification as well as their advantages and disadvantages.

This article is the continuation of temporomandibular joint (TMJ) disorders-Part I. This article focuses on the intracapsular disorders of the TMJ and the most common types that we as a dentist encounter. The condition of the intracapsular structure of TMJ affects the position of the TMJs; it also affects the occlusal relation.
