Clinical profile of voiding dysfunction with uroflow electromyography correlation in children

Decrease in voiding frequency in children lead to improve the capacity of bladder which tends to reduce the intake of fluid as the child relies on table food for nutrition. The objective of the study was done to enumerate the clinical features of voiding dysfunction in children and correlate the clinical findings with uroflow electromyography (EMG) findings. A prospective clinical research conducted on children of 5-18 years old with the inclusion criteria of children attained bladder control, no complaints of infection of urinary tract and normal neurological status. A sum of 20 children were taken for this study. While the child was passing urine; rate of flow, amount of urine voided, peak flow rate and time to void were recorded. Shape of the curve obtained as uroflow was also studied. Sphincter activity was noted by uroflow electromyography machine. The uroflow electromyography testing in 17 children (85 %) of 20 was abnormal. The various abnormalities included staccato voiding, fractionated voiding and sphincteric contraction during the voiding phase. In 11 children with history of prior urinary tract infection (UTI), 8 exhibited abnormal voiding on uroflow electromyography. Increased frequency as symptom was noted in 16 children with abnormal uroflow electromyography findings. Fourteen children who were unable to control the urge to void exhibited abnormalities on their uroflow electromyography. Uroflow electromyography to be a useful tool in the management of children with voiding dysfunction as it helped in the identification of the exact nature of the problem on an objective basis.

COPING AND BAR RETAINED TOOTH SUPPORTED OVER DENTURE A VIABLE OPTION TO PRESERVE THE PROPRIOCEPTION AND RESIDUAL BONECASE REPORT

Prosthetic treatment with overdenture is a favoured treatment modality for elderly patients with few remaining teeth and roots that are maintained under the denture base to preserve the residual ridge. The tooth supported overdenture provides the patient with a greater stability of the denture and improved masticatory function and esthetics. Retaining natural teeth as abutments for dentures can considerably reduce the progress of residual ridge resorption. Multiple abutments can be used to retain proprioception and prevent further bone resorption. This clinical report describes two cases that were successfully rehabilitated with tooth supported overdentures with high retention and esthetics.

Dimensional Stability and Accuracy of Silicone Impression Materials after Ozone Water Disinfection: An In Vitro Study

Objectives: This study evaluated the effect of ozone water disinfection on dimensional stability and accuracy of silicone impression materials. Materials and Methods: According to ISO-4823, a stainless-steel die was fabricated for this in vitro study. Three horizontal parallel lines, namely x, y, and z (25, 50, and 75µm in width and 25mm in length) running perpendicular to two vertical lines, namely D1 and D2 (0.075±0.008mm wide), were created on the superior surface of the die. Group A served as the control group with no disinfection. Disinfection was performed with 2% glutaraldehyde in group B, 5.25% sodium hypochlorite in group C, and ozone water in group D for 10 minutes. Totally, 60 samples were fabricated. The silicone impression samples were allowed to polymerize in a thermostatically controlled water bath at 35±1ºC for 10 minutes. The dimensional stability and accuracy of the silicone impression samples were evaluated by using a video measuring microscope and an optical microscope. Data were analyzed by two-way ANOVA followed by post-hoc analysis with the Scheffe test (alpha=0.05). Results: The highest dimensional stability (25.01mm) and accuracy (25.02µm) were seen in addition silicone putty and light body impression with ozone water disinfection, and the lowest parameters were seen in condensation silicon putty and light body disinfected with 2% glutaraldehyde (24.87mm and 24.88 µm, respectively); this difference was statistically significant (P<0.001). Conclusion: Ozone water disinfection caused minimal changes in dimensional stability and accuracy when compared to 2% glutaraldehyde and 5.25% sodium hypochlorite disinfectio

FULL MOUTH REHABILITATION OF SEVERELY WORN DENTITION WITH LOSS OF VERTICAL DIMENSION- A CASE REPORT

Prosthetic rehabilitation of severely attritted teeth with loss of vertical dimension is a real challenge due to little space available for rehabilitation. A valid treatment modalities is needed to increase the VDO to enable space for the prosthesis to enhance aesthetic, maintain anterior teeth relationships, and minimize the need for invasive procedures and endodontic treatments. Proper diagnosis and treatment sequences necessary to obtain successful results. This clinical report showed the successful management of badly mutilated dentition using conventional method KEYWORDS: Attrition, Full mouth rehabilitation, Mutilated Dentition, Vertical Dimension at Occlusion</jats:p

Evaluation of flexural strength and surface hardness of heat activated provisional PMMA resin reinforced with nanoparticles-an in vitro study

The provisional restorations are subjected to vertical, lateral and horizontal forces during function, hence the mechanical properties of the provisional materials to be taken into account before choosing for clinical use. The objectives of the study were to evaluate and compare the flexural strength and surface hardness of heat polymerized provisional polymethylmethacrylate resin reinforced with 2.5% Zirconia, Titanium or Aluminum oxide nano-particles. According to ISO 10477:2018, die was made in 25 mm x 2 mm x 2mm for flexural strength and wheel die in 15 mm diameter and 1mm thickness for hardness test. A total of 160 samples were fabricated and divided into Groups. I- (samples kept in distilled water for 24 hours after fabrication) and Group. II (samples kept in artificial saliva for 2 weeks after fabrication) and subdivided into Group-a(control), samples reinforced with 2.5% Zirconia nanoparticle (Group b), samples reinforced with 2.5%Titanium oxide nanoparticles (Group c), samples reinforced with 2.5% Aluminum oxide nanoparticles (Group d). The flexural strength was evaluated by three-point bending test and the hardness was evaluated using digital Vickers micro hardness tester. The values were statistically analyzed using one way ANOVA and Tukey’s HSD test at significant level P&lt;0&gt; Keywords: Flexural strength, Heat activated PMMA resin, Provisional restoration, Surface hardness.</jats:p
