ABSTRACT
BACKGROUND: Golden proportion is a constant ratio that exists in nature, responsible for the esthetic appeal of parts in the human body. The study was aimed to assess the existence of golden proportion in primary dentition by evaluating the average width and height ratio of maxillary anterior teeth. MATERIALS AND METHODS: A total of 200 children comprising equal number of males and females aged 3-7 years with all deciduous teeth present were randomly selected. Each participant was photographed with head upright and occlusal plane parallel to floor. Distance between the participant and camera was fixed at a working distance of 60 cm. The digital images were analyzed using imaging software (Adobe V7), the perceived widths of maxillary laterals were divided by widths of central incisor and that of canines were divided by perceived widths of lateral incisor. Maxillary arch impressions were made and casts prepared. Measurement of each anterior tooth was done using digital calipers. The measured width of lateral incisor was divided by width of central incisor and that of canine was divided by measured width of lateral incisor. Perceived and measured widths were tabulated separately. RESULTS: The mean measured lateral incisor-to-central incisor ratio was 0.80. The mean measured canine-to-lateral incisor ratio was 1.32. The mean perceived lateral incisor-to-central incisor ratio was 0.75. The mean perceived canine-to-lateral incisor ratio was 0.90. The mean measured width-to-height ratio of central incisors was 1.14. The mean perceived width-to-height of central incisors ratio was 1.08. No significant statistical difference was observed between measured widths, perceived widths, measured width-to-height ratio, and perceived width-to-height ratios for both the sexes. There was strong correlation between these ratios and golden ratio (0.62). CONCLUSION: The study revealed that the golden proportion was inconsistent in terms of relative tooth width in primary dentition.
ABSTRACT
INTRODUCTION: Most children are casual and moderately agreeable in the dental treatment environment, however some of them show practices that upset the professional and make the protected conveyance of worthy treatment extremely troublesome. For such cases dental practitioner utilizes behavior management techniques. At the point when behavioral administration procedures come up short, some type of pharmacologic sedation or anesthesia may be an important and vital option. Dental sedation is a strategy in which the utilization of a medication or drugs produce(s) a condition of depression of the central sensory system empowering treatment to be completed during which verbal contact with the patient is kept up all through the time of sedation. AIM: This study was designed to evaluate and compare the effectiveness of oral midazolam and oral ketamine in combination with N2O-O2 in children undergoing dental treatment. MATERIALS AND METHODS: This study involved a sample of 30 pediatric dental patients (age range is 3-9 years), whose selection criteria included ASA I & II health status, cooperative but apprehensive behavior and a need for multiple dental extractions. The patients were assigned to receive oral midazolam on their first visit and on the follow up visit they received oral ketamine. Nitrous oxide (30%) was used during each sedation visit. Physiological parameters like Respiratory Rate (RR), pulse rate, and oxygen saturation were evaluated for each procedure, followed by the use of modified Bender Visual Motor Gestalt Test to evaluate psychomotor effects. Data were analyzed using Independent sample student t -test. RESULTS: Analysis of the data showed statistically no significant difference (p >0.05) on comparison of effectiveness of oral midazolam-N2O with oral ketamine-N2O when pulse rate, oxygen saturation and respiratory rate were taken into consideration. Psychomotor performance was found to be marginally better with oral midazolam-N2O compared to oral ketamine-N2O. CONCLUSION: Both the drugs were effective in reducing the patient anxiety while undergoing dental extractions. Though the t-test results were not statistically significant with respect to physiological parameters. Oral midazolam-N2O showed marginally better results compared to oral ketamine-N2O with respect to psychomotor effects.
ABSTRACT
AIMS AND OBJECTIVES: The chemomechanical caries removal system is made presently available containing a natural proteolytic enzyme for ease in the excavation of infected dentin. The aim of the study was to evaluate the efficacy and efficiency of caries removal using Papacarie(®) and Carie-Care™. MATERIALS AND METHODS: A total of 30 extracted deciduous molars with proximal caries were collected, and each tooth was sectioned mesiodistally in the center of the carious lesion so that the two halves (buccal and lingual or palatal) have similar carious lesions, thus 30 teeth yielded 60 specimens. The specimens from each tooth were divided alternatively into two groups for caries excavation either using Papacarie(®) or Carie-Care™ so as to avoid selection bias. Paired t-test was used to compare mean time taken for caries removal and Fischer's exact test was done for comparing bacterial remnants after caries excavation. RESULTS: Mean time taken for caries removal was significantly higher for Carie-Care™ (427.13 s) when compared to Papacarie(®) (385.8 s). Papacarie(®) was found to be significantly more efficient in caries removal with marked reduction in the bacterial remnants following excavation. However, both gels were found to be conservative as dentinal tubule destruction was not evident in either of them. CONCLUSION: Both Papacarie(®) and Carie-Care™ were found to be conservative in caries removal. Papacarie(®) was more efficient in removing bacteria in lesser time from the infected carious lesion.
ABSTRACT
CONTEXT: Dental caries continues to affect a significant portion of the world population and treatment of the decay is associated with pain by many patients. Intervention and application of rotary instruments for treatment of carious lesions has often resulted in considerable removal of tooth structure. Chemo-mechanical method, a minimal invasive technique for caries removal was developed to overcome these shortcomings. This innovative method seems to be efficient in removing infected dentine without altering the healthy dental tissue or harming the adjacent oral mucosa. AIM: To evaluate the efficacy and efficiency of Caries removal Using Polymer Bur, Stainless Steel Bur, Carisolv and Papacarie. MATERIALS AND METHODS: A total of 120 sectioned specimens were obtained from 60 extracted teeth. Each tooth was sectioned mesiodistally in the center of the carious lesion so that two halves (buccal and lingual or palatal) having equal sized carious lesions are compared. The sectioned specimens were subdivided into four groups (Polymer Bur, Stainless Steel Bur, Carisolv, Papacarie) allotting 30 specimens to each for caries excavation. RESULTS: One-way ANOVA, Chi-square test analysis was done for comparison between groups which showed significant results with Stainless Steel Bur excavation taking less mean time when compared to other agents and Polymer Bur showed more amount of bacterial remnants after excavation whereas Carisolv and Papacarie were efficient with less dentinal tubule destruction and bacterial remnants after excavation. Further inter comparison between groups was done using Paired t-test and Fischer's Exact-test. CONCLUSION: The Mean time taken by Stainless Steel Bur excavation was found to be less and caused more amount of dentinal tubule destruction when compared to Polymer Bur, Carisolv and Papacarie. Chemo-mechanical methods found to be more efficient with lesser amount of bacterial remnants and dentinal tubule destruction after caries excavation when compared to conventional methods.
ABSTRACT
INTRODUCTION: Pulpotomy technique basically consists of removing the coronal pulp and fixing the radicular pulp with a medicament. It is the most widely accepted clinical procedure for treating primary teeth with coronal pulp inflammation caused by caries with no involvement of the radicular pulp. AIM: To evaluate the success and efficacy of Mineral Trioxide Aggregate (MTA), Lasers and Biodentine as pulpotomy agents both clinically and radiographically. MATERIALS AND METHODS: In the present study, 60 primary molars in children whose pulpal status warranted pulpotomy were selected and randomly assigned into three groups that included MTA, Laser and Biodentine allocating 20 teeth to each group. The pulpotomy procedure was then performed on all selected teeth followed by restoration with stainless steel crowns. Later the patients were recalled for 3 months and 6 months for clinical and radiographic evaluation. RESULTS: Statistical analysis was done using Fisher exact test to determine pair wise comparison of three agents with respect to clinical and radiographic criteria. Kruskal-Wallis ANOVA, Mc Nemars test was applied to evaluate the efficacy of each agent between 3 months and 6 months. The results showed that maximum success rate was found in MTA group. However, the comparison between three groups was statistically not significant (p<0.05). CONCLUSION: Pulpotomies performed with either MTA, Laser or Biodentine are equally efficient with similar clinical/radiographic success and hence can be considered as alternatives to Formocresol.
