Comparative Evaluation of the Efficacy of Intraligamentary and Supraperiosteal Injections in the Extraction of Maxillary Teeth: A Randomized Controlled Clinical Trial

Mandible bone is the largest and the strongest bone present in the human face. It is a lower jaw bone that is present beneath the maxilla. It holds the lower teeth. Mandible bone is formed from the first pharyngeal arch during its intrauterine life. This bone provides maximum attachment of muscle of mastication and facial expression. The body of the mandible has 2 borders. Ramus of the mandible is a prominent projecting back parts of the horse shoe shaped lower jaw bone. The antegonial notch is present in the inferior border of the mandible at the junction between the ramus and body of the mandible. At the level of the molar occlusal surface there is distinct angulation of the ramus of mandible in its posterior border. This type of angulation on the posterior border is known as posterior ramus flexure. The aim of this research is to morphologically analyse the antegonial notch and posterior ramus flexure and its clinical importance. Fifty-one dry adult human mandibles of unknown sex collected from the Department of Anatomy of Saveetha Dental College. For each mandible, detailed measurements of Antegonial notch and Posterior ramus flexure were taken. There is a presence of 3 types of Antegonial notch and 3 types of Posterior ramus flexure that were discovered and measured separately in fifty-one dry adult human mandibles of unknown sex. The shape, size and the position of the antegonial notch and posterior ramus flexure can be used as one of the tools as an indicator for Sexual Dimorphism. Other researchers have found many indicators for sexual dimorphism as a tool to identify the sex, age, race, etc. There is various evidence that represent and identifies the difference between sex, age and gender and many anatomical features supports it.

Morphometric Analysis of Locations, Shape and Variations of Spine of Sphenoid and its Clinical Importance

The sphenoid bone is the unpaired bone in the cranium.It is present in the middle of the skull and it is an important surgical site. It is butterfly shaped with wings on either side that includes a greater wing and lesser wing of sphenoid. It has various attachments and foramina associated with it.The posterior part of greater wing projects like a triangular process called as sphenoidal spine which is the origin for sphenomandibular ligament.The aim is to study the morphometry of the location, shape, and variations of the spine of sphenoid and its clinical importance in different skulls of the south indian population.For this 30 adult dry human skulls of unknown sex of south indian origin were obtained from the Department of Anatomy, Saveetha Dental College, Chennai, Tamilnadu, India. All skulls were serially numbered from 1 to 30. In each skull, the shape of the spine of the sphenoid was observed and recorded. The distance of the spine from the tip of mastoid process and tip of the articular tubercle were measured on both the right and left sides of the skull using digital Vernier calipers. All data were tabulated and statistically analysed.The range of distance between the spine of sphenoid and the articular tubercle is found to be about 20.17-29.32mm(left) and 20.16-29.19mm(right) and the distance between the spine of the sphenoid and the mastoid process is found to be around 29.17-32.7mm(left) and 29.27-32.79mm(right). It is found that about 6.6% of spine is sharp, 46.6% is rounded in both left and right side, 26.6% is blunt on left side and 23.3% on the right side and about 20% on left and 23.3% on the right side were pointed type. The purpose of this study is to verify the morphometric variations in the location, shape of spine of sphenoid in different dry skulls of south indian and to find out its applications in various surgical procedures.

“…Various depigmentation techniques have been employed in the recent years. (Patil et al, 2015) Previously we have worked on plenty of topics in periodontology (ramesh, ravi and Kaarthikeyan, 2017;ravi et al, 2017;Arjunkumar, 2018;Gajendran, Parthasarathy and Tadepalli, 2018;Jain and nazar, 2018;Kavarthapu and Thamaraiselvan, 2018;ramesh et al, 2018Ezhilarasan, Apoorva and Ashok Vardhan, 2019;Kaarthikeyan, Jayakumar and Sivakumar, 2019;Kavarthapu and Malaiappan, 2019;Murthykumar, Arjunkumar and Jayaseelan, 2019;Vijayashree Priyadharsini, 2019). now we are planning to work on the knowledge and awareness on esthetic procedures in periodontics among undergraduate dental students.…”

Knowledge and Awareness About Esthetic Procedures in Periodontics Among Undergraduate Dental Students

2020

The current level of awareness on beauty has driven a higher demand for aesthetic dentistry. The shape, position and appearance of the gingival tissue influences the aesthetics of the smile. Various techniques for gingival deformities have been introduced in recent years to meet the aesthetic needs of the patient with functional requirements. The aim of this study was to evaluate the knowledge and awareness about esthetic procedures in periodontics among undergraduate dental students. A 7-item questionnaire was prepared and circulated through an online portal among undergraduate dental students. A total of 100 students took up the survey among which 28 students were males and 72 students were females. The results obtained from the survey were tabulated, analysed and represented graphically using SPSS software (Version 23). Frequency distribution and percentage and chi-square test were done. In the present study, 86% of the undergraduate students were aware of gummy smile, 72% were aware of black triangle and 90% were aware of gingival hyperpigmentation. However, the knowledge on the treatment modalities for such conditions were inadequate. 48% were not aware of the treatment options for gummy smile, 42% were not aware of various gingival depigmentation techniques. Also, females had more knowledge and awareness as compared to males. This study emphasizes the need for more awareness about the esthetic procedures in periodontics must be created among undergraduate dental students.
