“…Therapeutic treatment of carious lesions and their complications in the intussusception area requires a high level of professionalism and endodontic skills [4][5][6][20][21][22]]. An early diagnosis of these lesions is crucial as they may adversely affect any planned orthodontic treatment, and therefore, an assessment of the prognosis of these lesions is required before starting orthodontic treatment [23]. The diagnosis of these formations usually occurs when patients seek specialist treatment for an acute therapeutic process and main orthodontic deformity or during routine examinations.…”

In the process of odontogenesis, a disturbance in the formation of the epithelium and mesenchyme can be observed and this can be manifested by atypical forms of dental development. Such biological phenomena with altered morphology are as follows: dens invaginatus (DI), dens evaginatus (DE), talon cusps, and double teeth (DT) or connate teeth (fusion and gemination). Patients with orthodontic anomalies who also exhibit teeth with morphogenetic disorders are presented in this article. Dens evaginatus and talon cusps pose orthodontic challenges in the treatment finishing phase. These reduce the possibility of achieving maximum intercuspidation between the lower and upper front teeth as well as poor incisor guidance. Other orthodontic challenges are as follows: the risk of occlusal trauma and periodontal loading of the antagonists and the possibility of accessory cusps to play the role of the inclined plane and lead to deviations in the closure of the lower jaw. The fused teeth can cause aesthetic and occlusal disturbances in the anterior segment. Furthermore, double teeth can lead to ectopic eruption or noneruption of adjacent teeth due to their increased crown size as is the case with one of the presented patients. This is because a double tooth occupies more space in the dental arch. If not diagnosed early, impaction of the adjacent tooth, violation of the occlusal ratios (Bolton/anterior), and exacerbation of the orthodontic deformity can be observed. The modern CBCT imaging is the best diagnostic method for identifying problems related to tooth positions or tooth germs.

“…So it can be fulfilled with this kind of research in the south indian population between the left and right side. Our team has extensive knowledge and research experience that has translated into high quality publications [12][13][14][15][16][17][18][19][20][21][22][23][24][25][26][27][28][29][30][31]. This study aims at accurate morphological and morphometrical measurements of human scaphoid bone between left and right side in the south indian population.…”

Introduction: Scaphoid is the second largest among all the carpal bones, which is present on the radial side of the proximal row of carpal bones. Scaphoid Fractures are the most common of the carpal bone injuries. Scaphoid Fractures heal slowly due to thelimited blood circulation of the bone Materials and Methods: The study was performed on 20 Scaphoid Bones,which were collected from the Department of Anatomy,Saveetha dental college. By using digital vernier callipers,morphological and morphometrical parameters (length and breadth)of scaphoid bones were measured,tabulated and statistically analysed. Results: All the 20 scaphoids showed the presence of tubercle. Double foramina in the main dorsal sulcus were seen in 7 right and 6 left specimens. No significant differences were found in lengths and breadths of the bone.In the present study, at least one foramen is found in all the main dorsal sulcus and the number of specimens showing presence of double foramen in the main dorsal sulcus are 7 right and 6 left specimens. Conclusion: This study showed that no significant morphological and morphometric differences were found between right and left sides. The data obtained in the present study will be helpful for the hand surgeons, radiologists and clinical anatomists for surgical reduction to follow up the reunion of fractured scaphoid bones.

Introduction: Mastoid process is a pyramidal bony projection . It is located in the posterior inferior region of the temporal bone. Mastoid notch is on the medial side of the mastoid process. Clinical significance causing infection of the middle ear could spread to the mastoid area causing mastoiditis. The aim of the study is to determine the morphometric and morphological analysis of mastoid process and mastoid notch in dry human skull and their clinical implication. Materials and Methods: The present study was taken from the department of Anatomy in Saveetha Dental College and Hospital by taking 72 dry human skulls. Digital vernier caliper was used to measure the mastoid process and mastoid notch of different parameters. The data was measured and analyzed statistically, using paired sample ‘t’ tests. Results: The present study shows 0.641 significance in the right and left length of the mastoid process which is not significant. Right breadth and left breadth of the mastoid process of 0.007 and mastoid notch of right and left length 0.00 are significant. Conclusion: It concludes that the mastoid process and mastoid notch have varied significant differences in the dry human skulls. This study will be helpful in mastoid surgeries.
