ABSTRACT
Introduction: Developmental anomalies of the tooth areroutinely encountered by paediatric dental professionalsand may present with esthetic and or functional problems.The reported literature has shown a wide variation in theprevalence of these conditions across the globe. Study aimedto assess the prevalence of various developmental anomaliesof tooth in a sample of Indian paediatric populationMaterial and Methods: A total of 3000 children in the agegroup of 6 to 13 years visiting the OPD of pedodontics andpreventive dentistry of BIDSH, Patna were examined clinicalyand radiologicaly when required and the data was tabulated.Descriptive statistics methods were used using SPSS.Results: Prevalence of dental anomalies was 4.86%.in thestudy population and Enamel hypoplasia, hypodontia andtalon's cusp were the most frequently encountered anomalies.The presence of developmental anomalies was a statisticalysignificant finding.Conclusion: Early detection of developmental anomaliesmay prevent future complications and eliminate the need forcomplex therapeutic intervention.
ABSTRACT
Introduction: Cross infection control practice is essential toprotect both the patient and the dentist from blood and salivaborne infectious agents, including hepatitis B, C and HIV bydirect contact with contaminated instruments, fabrics and alsoby aerosols. Study aimed to assess the awareness regardingpractices related to infection control among dental student inPatna city.Material and Methods: This was a cross sectional studywhich was carried out in one of the dental teaching institutionsin Patna City. The subjects comprised of 180 dental students.The study subjects were third year; final year and Internstudents which were selected using convenience samplingtechnique. Their knowledge pertaining to infection controlpractices were assessed using a pretested self administeredquestionnaire. The questionnaire collected information onsocio demographic characteristics, and knowledge regardinginfection control practices. Data were analyzed using SPSSsoftware v20. Frequency distribution analysis and Chi sq testswere performed. p value<0.05 was considered statisticallysignificant.Results: The dental student had adequate knowledgeregarding personal protective measures and cross infectioncontrol but improvement was needed in areas of biomedicalwaste handling and disposal.Conclusion: A dental surgeon must take adequate protectionto prevent spread of harmful disease to self and other patients.Consequently inter-appointment disinfection of clinic surfacesis required to reduce the cross infection hazard.
ABSTRACT
Introduction: The aim of mandibular fracture treatment isto restore the pre-injury anatomic form and function, withparticular care to establish the occlusion. Of the varioustreatment modalities available, Champys miniplate fixation hasbecome the most widely used technique. The 3-dimensional(3D) plating for mandibular fracture treatment is relativelynew. This study was conducted to compare efficacy, stabilityand rigidity of 3-dimensional plates with that of 2mm titaniumminiplates in the surgical management of anterior mandibularfractures.Material and Methods: The study was conducted on 70patients with anterior mandbibular fractures (Symphysis andParasymphysis region). Patients were randomly divided intotwo groups, Group I (n=35) in which the patients underwentfixation by miniplates (2 nos) while in Group II (n=35), 3Dplates were used for fixation. The patients preoperative, intraoperative and post-operative clinical and radiological findingswere recorded in a proforma and were subjected to statisticalanalysis. Fisher’s Exact Test was used to compare the dataobtained from group I and group II patients.Results: Out of 70 patients, 77.14% corresponded to the agegroup of 15-30 years and 82.85% were males. Road trafficaccident (80) % was the leading cause of fracture. The timerequired to adapt and fix the miniplates was slightly more than3-D plates and results were statistically significant. Skeletaland occlusal stability was maintained in both group.Conclusion: There is no major difference in terms of treatmentoutcome in both systems, and both are equally effective inmandibular fracture treatment.
ABSTRACT
Introduction: An asymmetrical face consists of multitude of the minor asymmetrical component, the mandibular component being most common. The asymmetric mandibular prognathism (AMP) is one of the most common forms of asymmetry caused by genetic and epigenetic factors and environmental condition such as trauma, functional deviations due to dental interference. The present study was undertaken to assess the effi cacy of a modifi ed bilateral sagittal split osteotomy (BSSO) technique in correction of AMP. Purpose: The purpose of the study was to investigate the skeletal stability and changes of proximal segments position postoperatively following surgical correction of AMP with modifi ed BSSO technique and analyze the effect of such changes on the incidence of signs and symptoms of temporomandibular joint (TMJ) disorders. Materials and Methods: Patients with AMP were included in the study. All the patients underwent surgical correction by modifi ed BSSO technique. The patient clinical and cephalometric fi ndings (pre-operative, immediate post-operative, and 6 months postoperatively) were recorded in a proforma and subjected to statistical analysis. Results: A total of six (n = 6) participated in the study. Five out six patients had pre-existing TMJ problems. In lateral cephalogram, the mean mandibular setback of Point B was 7.75 mm. In frontal cephalogram, the mean mandibular deviation decreased 2.55 mm after surgery. Minimal relapse was noted 6 months post-operatively suggestive of good skeletal stability with minimal complications. Conclusions: The modifi ed BSSO technique was effective in the treatment of AMP.
