It was concluded that pain perception was significantly more during traditional palatal infiltration injection as compared to computerized palatal infiltration, while there was no difference in pain perception during buccal infiltration in both the groups.
Facial asymmetry is an individualized characteristic and is commonly observed sub clinically in overall population. However, clinically significant facial asymmetry with associated morphologic, esthetic and stomatognathic problems warrant investigation of the underlying etiology and comprehensive clinical examination in conjunction with imaging studies for diagnosis, localization of asymmetry and treatment planning. The principal aim of this article is to present an invaluable insight into etiopathogenesis, myriad classifications and various systematic diagnostic approaches indispensable for formulation of treatment plan and appropriate management of facial asymmetry.
Aim:The purpose of this study was to compare the efficacy of platelet-rich plasma (PRP), platelet-rich fibrin (PRF), and hydroxyapatite (HA) for reduction of pain and swelling, absence of dry socket, soft tissue healing, and bone regeneration after mandibular third molar extraction in human patients.Materials and Methods:Forty patients requiring extraction of mandibular third molars were randomly grouped as control, PRP, PRF, and HA-treated. The patients were assessed for postoperative pain, swelling, dry socket, and soft tissue healing on the 3rd, 7th, and 14th day of postoperative periods depending on the standard methods. Radiological assessment of the extraction site was done at 1, 2, and 6 months interval to compare the change in bone density in the sockets in control and treated patients.Results:Pain and swelling were less on PRP and PRF site when compared to HA and control site. PRP and PRF site showed better soft tissue healing when compared to HA and control site. Radiographic assessment showed comparatively lesser bone density values in PRP, PRF, and control site at 1, 2, and 6 months than HA site.Conclusion:Our study showed that PRP and PRF are better graft materials than HA regarding pain, swelling, dry socket, and soft tissue healing. Bone regeneration is induced promptly by HA as compared to other graft materials. However, a more elaborate study with a larger number of clinical cases is very much essential to be more conclusive regarding the efficacy of the graft materials.
Grain legumes remain important to meet the projected targets relating to food and nutritional security worldwide. The complementation of cereal-based food with grain legumes is a vegetarian diet with high-quality protein.However, the performance of these crops is severely influenced by a number of biotic and abiotic stresses, of which pests and pathogens remain the crucial affecting plants at different growth stages. Chemical pesticides are mainly employed across the world for management of pests and pathogens. The risk associated with the environmental pollution and health hazards to man, plants, domestic animals, and wild life makes these pesticides ecologically unacceptable. Also, major damage caused by pests of grain legumes are systemic in nature, and their management through chemicals often yields unsatisfactory outcome. This has led to increasing shift in the attention of scientific community towards eco-friendly and safer technologies for pest management in legumes. Sustainable protection demands implementation of strategies that rely upon biological control agents (BCAs) and their formulations. In recent years, such formulations have been promoted to mitigate the pest problem and improving crop yield. This review presents an updated summary on BCAs including the present status of BCA application, mode of actions, and delivery systems under controlled and field conditions to address major pest problems on legume crops.
Background:It is important that every member of our community should be trained in effective BLS technique to save lives. At least doctors including dental practitioners, and medical and paramedical staff should be trained in high quality CPR, as it is a basic medical skill which can save many lives if implemented timely.Aim:Our aim was to study the awareness of Basic Life Support (BLS) among dental students and practitioners in New Delhi.Materials and Methods:This cross sectional study was conducted by assessing responses to 20 selected questions pertaining to BLS among dental students, resident doctors/tutors, faculty members and private practitioners in New Delhi. All participants were given a printed questionnaire where they had to mention their qualifications and clinical experience, apart from answering 20 questions.Statistical Analysis:Data was collected and evaluated using commercially available statistical package for social sciences (SPSS version 12).Results:One hundred and four responders were included. Sadly, none of our responders had complete knowledge about BLS. The maximum mean score (9.19 ± 1.23) was obtained by dentists with clinical experience between 1-5 years.Conclusion:To ensure better and safer healthcare, it is essential for all dental practitioners to be well versed with BLS.
Teeth having open apices in the absence of a natural apical constriction pose several challenges during conventional endodontic treatment, especially when establishing an apical seal. Treatment is further challenging when these teeth are associated with large periapical or cystic lesions having resulted in expansion and/or thinning of adjacent cortical plates. Although surgical intervention is commonly adopted in the management of such cases, a conservative treatment option offering equally good prognosis is always desirable. This case series describes 3 cases: a 39-year-old woman, a 45-year-old woman, and a 15-year-old boy having teeth with concomitant open apices and large periapical/cystic lesions managed conservatively by (1) following a strict intracanal disinfection protocol, (2) intracanal aspiration with digital decompression of associated swelling, and (3) 1-step apexification for closure of the root apex by placing a preliminary barrier of platelet-rich fibrin (PRF) and a secondary barrier of Biodentine (Septodont, Saint-Maur-des-Fossés, France). In all 3 cases, the treatment outcomes, both clinical and radiographic, were highly satisfactory. PRF and Biodentine collectively rendered an apical plug that proved to be a suitable alternative to commonly used mineral trioxide aggregate in 1-step apexification. Biodentine provides good interfacial adhesion and sealing with dentin attributed to its property of hydroxyapatite crystal deposition at the material-dentin interface. Also, because of its bioactivity, it likely promotes the conversion of adjacent PRF into a calcific barrier, thus reinforcing the apical seal. Additionally, host-modulating responses of PRF contribute in expediting the healing process. Reasonable osseous healing in the periapex could be appreciated as early as 3 months in all patients. The rapidity with which healing occurred may have been an incidental finding but definitely draws attention.
Pulpal regeneration after tooth injury is not easy to accomplish. In teeth with immature apices and exposed vital pulp tissue, partial or complete pulpotomy is indicated to preserve pulpal function and allow continued root development. In many cases, injury causes loss of pulp vitality and arrested root development leading to a tooth with poor crown root ratio, a root with very thin walls, an open blunderbuss apex and development of apical pathosis.
scite is a Brooklyn-based organization that helps researchers better discover and understand research articles through Smart Citations–citations that display the context of the citation and describe whether the article provides supporting or contrasting evidence. scite is used by students and researchers from around the world and is funded in part by the National Science Foundation and the National Institute on Drug Abuse of the National Institutes of Health.
