Authors: Narayanan Arun , Mendon Chaya 
Published: June 2013

ABSTRACT

Purpose
Several antiplaque agents are being available in the market in spite of vast development of modern medical science, satisfactory treatment of ‘oral diseases’ by newer drugs is not fully achieved, rather the chemical compounds has exposed the patients to it is different ill effects, therefore, there is interest to find out effective remedy of any disease by harmless herbal drugs thus the aim of this study was to compare plaque formation at 24 hours after the use of Triphala, Hi ora, Chlorhexidine and colgate plax mouth washes.

Methods
A controlled, randomized, double-blind, crossover clinical trial was designed. Thirty subjects underwent four consecutive experimental phases with four treatments: Triphala, Hi Ora, Chlorhexidine and colgate plax. On the day of study, the subjects discontinued all other oral hygiene habits and were randomly assigned for treatment with the experimental mouthwash. Each experimental phase was preceded by a 28- day washout period. Plaque formation was recorded after one undisturbed day.

Results
Triphala, Hi Ora and Chlorhexidine reduced de novo plaque formation to a greater extent than the colgate plax mouthwash (p < 0.05).

Conclusion
Triphala and Hi Ora presents an anti-plaque efficacy similar to that of chlorhexdine, and was more effective at inhibiting plaque formation than the colgate plax mouth wash.

Comparison of Chemical Aging and Water Immersion Time on Durability of Resin-Dentin Interface produced by an Etch-and-Rinse Adhesive
Authors: Botta Sergio Brossi , Matos Adriana Bona , Garbui Bruna Uglik , Reis Andre Figueiredo 
Published: June 2013

ABSTRACT

Aim
The aim of this study was to analyze and compare the influence of short-term NaOCl-storage and long-term water storage on the microtensile bond strength (μTBS) of etch-andrinse adhesive system to human dentin.

Materials and methods
Thirty-six third human molars were randomly divided into 6 groups (n = 6) according to the aging protocol: G1 (water, 24 hours); G2 (water, 6 months); G3 (water, 12 months); G4 (10% sodium hypochlorite – NaOCl, 1 hour); G5 (10% NaOCl, 3 hours) and G6 (10% NaOCl, 5 hours). A two-step etch-and-rinse adhesive (Adper Single Bond 2) was applied according to the manufacturers¡¦ instructions. A composite (Filtek Z250) was applied in four horizontal increments and was individually cured. Specimens were cut following the microtensile test technique, submitted to the different aging protocols, and tested in tension. The fracture pattern was observed in a stereomicroscope (40× magnification) and in a scanning electron microscope. The μTBS data were analyzed by ANOVA and Tukey's test (α = 0.05).

Results
The effect of storage in 10% NaOCl for 1 or 3 hours was not significantly different from that of aging in distilled water (DW) for 6 or 12 months (p > 0.05). Beams immersed in DW for 24 hours and in 10% NaOCl for 5 hours showed the highest and lowest ìTBS values respectively.

Conclusion
The aging protocols negatively influenced dentin bond strength. Aging specimens in 10% NaOCl for 1 or 3 hours can be an alternative method for long-term water storage (6 or 12 months) bond strength studies.

Clinical significance
This aging protocol allows a quick achievement of longitudinal bond strength data, so that results are available to the professionals in this area while the materials are yet present at the dental market.

Published: June 2013

ABSTRACT

Aim
To evaluate the mechanical properties (ultimate tensile strength, elongation and hardness) of the commercially pure titanium (cp Ti) as casting and after ceramic firing cycles.

Materials and methods
Dumbbell-shaped specimens were prepared for the tensile strength testing. Disk-shaped cast specimens were used for microhardness testing. The ceramic firing cycles were made simulating a low fusion ceramic application. Tensile testing was conducted in a universal testing machine at a crosshead speed of 1 mm/min until failure. Ultimate tensile strength and elongation were recorded. The fracture mode was analyzed by scanning electron microscopy. Vickers hardness was measured in a hardness tester. The data from the tensile and hardness tests were subjected to a one-way analysis of variance and Tukey's test (α = 0.05).

Results
The mean values of tensile strength were not changed by the ceramic firing cycles. Lower hardness was observed for cp Ti as casting compared with Ti cast after the firing cycles.

Clinical significance
The ceramic firing cycles did not show any considerable prejudicial effects on the mechanical properties of the cp Ti.

Comparison of Opal Self-Ligating Brackets with Manually Ligating Brackets
Authors: Deshpande Ashwin , Srinivas N , Kumar K Kiran , Mapare Sagar 
Published: June 2013

ABSTRACT
This study was conducted with aim to evaluate the efficiency of the newly introduced Opal self-ligating brackets (SLB). The chairside time saved, appliance efficiency, bracket bond failures, breakages and bracket staining in the Opal SLBs were compared with the conventional standard metal manually ligating brackets (MLBs) of MBT system. Seven patients were compared in each group. Standard light curing bonding methods were used in both the group. Chairside time saving, appliance efficiency and bracket bond failures were compared among the groups whereas staining was observed with the SLBs. Appliance efficiency was evaluated by PAR scores. Results showed significant chairside time being saved in SLBs, whereas the appliance efficiency was not significant. Bond failures were found only in SLBs as well as breakages along with staining. Henceforth, we could conclude that though SLBs had advantage of saving chairside time but also had disadvantage of losing more time with bond failures.

Evaluation of the Cadiax Compact® II Accuracy in Recording Preadjusted Condylar Inclinations on Fully Adjustable Articulator
Authors: Ahangari Ahmad Hasan , Torabi Kianoosh , Pour Sasan Rasaei , Ghodsi Safoura 
Published: June 2013

ABSTRACTBackgroundMandibular movement analysis is a critical step in making the functional occlusal morphology and improving the diagnosis and treatment of temporomandibular joint disorders (TMDs). Cadiax Compact® is an electronic condylograph that claims to record the horizontal condylar inclination (HCI), Bennett angle (BA) and relative shape of the articular eminence. This study aims at assessing the accuracy of Cadiax Compact® II in its claimed abilities.Materials and methodsThe electronic condylograph (Cadiax Compact®II) was fitted on the fully adjustable articulator (gamma dental reference- SL). After setting of HCI and BA on the arbitrary degrees, eccentric movements were produced manually on the articulator. The Cadiax recorded these preadjusted angles and the accuracy of its recordings was assessed by comparison of the results with the preadjusted HCI, BA and color inserts as references.ResultsThe majority of the comparisons showed statistically significant differences between articulator settings and Cadiax recordings. However, the maximum difference was about 2.5° which seems acceptable for clinical practice.ConclusionThe obtained results showed that Cadiax Compact is an accurate and reliable instrument for diagnostic purposes, yielding reproducible measurements. Despite this, Cadiax is a technically sensitive device that can preclude its routine usage.How to cite this articleAhangari AH, Torabi K, Pour SR, Ghodsi S.

Authors: Balamurugan R , Mohamed Masroor , Katikaneni Hari Krishna Rao , Kumar KR Ashok 
Published: June 2013

ABSTRACT
Any suture material, absorbable or nonabsorbable, elicits a kind of inflammatory reaction within the tissue. Nonabsorbable black silk suture and absorbable polyglycolic acid suture were compared clinically and histologically on various parameters.

Materials and methods
This study consisted of 50 patients requiring minor surgical procedure, who were referred to the Department of Oral and Maxillofacial Surgery. Patients were selected randomly and sutures were placed in the oral cavity 7 days preoperatively. Polyglycolic acid was placed on one side and black silk suture material on the other. Seven days later, prior to surgical procedure the sutures will be assessed. After the surgical procedure the sutures will be placed postoperatively in the same way for 7 days, after which the sutures will be assessed clinically and histologically.

Results
The results of this study showed that all the sutures were retained in case of polyglycolic acid suture whereas four cases were not retained in case of black silk suture. As far as polyglycolic acid suture is concerned 25 cases were mild, 18 cases moderate and seven cases were severe. Black silk showed 20 mild cases, 21 moderate cases and six severe cases. The histological results showed that 33 cases showed mild, 14 cases moderate and three cases severe in case of polyglycolic acid suture. Whereas in case of black silk suture 41 cases were mild. Seven cases were moderate and two cases were severe. Black silk showed milder response than polyglycolic acid suture histologically.

Conclusion
The polyglycolic acid suture was more superior because in all 50 patients the suture was retained. It had less tissue reaction, better handling characteristics and knotting capacity.

Published: June 2013

ABSTRACTAimThe purpose of this study was to verify the association between the facial type and the morphology of the upper central incisor, to potentially provide a guide for artificial tooth selection in esthetic and prosthetic rehabilitation.Materials and methodsThe sample consisted of 51 lateral teleradiographs (lateral cephalometric radiographs) and cast models of subjects with a naturally optimal occlusion and at least four of the six keys of Andrews, for optimal occlusion. The facial type was defined by two cephalometric measurements (SN.Gn and SN.GoGn) and classified into dolichofacial, mesofacial and brachyfacial after digitizing the radiographs. The incisor morphology was classified into quadrangular, oval and triangular after 3D digitizing the models and evaluation of the images by 12 dentists. The evaluation between the examiners was performed by Kappa test. In order to test the differences between the variables, it was used a chi-square test (5%).ResultsNo significant difference (p < 0.05) was found between the studied variables.ConclusionFacial type was not associated with the morphology of the upper central incisor, considering the methodology and population included in the present study.Clinical significanceUsing the facial type as a way to select the morphology of the upper central incisor proved to be inadequate in this study.How to cite this articleParanhos LR, Zaroni M, de Carli JP, Okamoto R, Zogheib LV, Torres FC.

Comparison of Working Length Determination using Apex Locator, Conventional Radiography and Radiovisiography: An in vitro Study
Authors: Kishor KM Nanda 
Published: June 2013

ABSTRACT

Aim
The purpose of this study was to compare the working length determination done using three methods, namely, apex locator (Foramatron D-10, Parkell), radiovisiography (Planmeca) and conventional radiography (Prostyle intra, Planmeca).

Materials and methods
In this experiment, to determine the working length, 35 single-rooted teeth were selected and each tooth was subjected to all the three methods of the working length determination. This was compared with the actual working length measured utilizing ground sections of the individual teeth.

Results
The results revealed that all the three methods located the apex nearly as accurately as the actual root canal length obtained by histological ground sectioning, and among three methods apex locator being the closest to the actual root canal length.

Conclusion
The study concludes that all the three techniques are equally effective in determining working length.

Evaluation of Marginal Alveolar Bone Height for Early Detection of Periodontal Disease in Pediatric Population: Clinical and Radiographic Study
Authors: Sardana Varun , Deshpande Shobha , Shigli Anand , Gogia Guneet 
Published: June 2013

ABSTRACT

Objectives
To establish a normal range for the radiographic distance between cementoenamel junction and alveolar bone crest and the factors affecting distances for the early assessment of periodontal disease in Dravidian pediatric population.

Methods
Fifty children aged 6 to 8 years were selected based on inclusion and exclusion criteria. Clinical and radiographic examination was performed. All the surfaces were examined starting from the distal surface of primary canine to the mesial surface of first permanent molar. The various risk factors like plaque, calculus, proximal caries, restoration and bleeding on probing were recorded. A pair of bitewing radiographs was taken for each child. Bitewing radiographs were traced and analyzed.

Results
It showed that CEJ-ABC distance in primary teeth is about 1 ± 0.5 mm. In the permanent teeth, it was found to be 0.6 ± 0.5 mm in 6 to 8 years age group. CEJ-ABC distance was also affected by different variables like physiologic (eruption and exfoliation) and pathologic factors (plaque, calculus, dental caries, restorations, stainless steel crowns, bleeding on probing and probing depth).

Conclusion
CEJ-ABC distances greater than 2.5 mm should be considered under recall and follow-up. Children and adolescents susceptible to periodontal disease should be identified by radiographic means as early as possible in order to prevent the advance of an otherwise possibly destructive disease. The concept of oral health examination and treatment must include examination of the periodontal status of the patient.

Enhancing White and Pink Esthetics using Porcelain Laminates in a Fluorosis Patient
Authors: Babu Ramesh , Taneja VK , Williams Cecil , Malhotra Anuj , Kiran Ravi 
Published: June 2013

ABSTRACT
Fluorosis can cause enamel degeneration to varying extent depending on the fluoride levels prevalent in that particular area. It can range from slight mottling of enamel to severe degeneration leading to demineralization and resultant discoloration. In the latter case, treatment options are limited to bonding of the outer surface of teeth either with composite or porcelain.

Clinical significance
Porcelain laminates offer an excellent solution to enhance esthetics in a patient with fluorosis as it combines the advantage of being highly esthetic along with being conservative in its penetration to enamel.

Authors: Goel Manish , Maheshwari Amit , Raju Dandu Sitarama , Veereshi AS , Naidu D Lakshmayya , Raju BHV Ramakrishnan 
Published: June 2013

ABSTRACT
Lower incisor extraction in orthodontic treatment was very rare modality of orthodontic treatment because there are few patients who meet the standards for such treatment. Proper diagnosis and treatment planning should be done to achieve good occlusion and facial esthetics. Criteria for lower incisor extraction included degree of crowding, tooth size discrepancy, pathologic condition, vertical overbite, sagittal incisal relationship, skeletal growth pattern and age of the patient. This article comprises of a case of class I malocclusion treated with lower incisor extraction, with comprehensive analysis, diagnosis and treatment planning, treatment results were satisfactory.

Clinical significance
Mandibular incisor extraction can be an effective treatment option in borderline cases with mild crowding in lower arch. Minimal alteration of mandibular arch form is key factor for success and stable results.

The Effect of Denture Cleansers on Resiliency of Soft Lining Materials
Authors: Reddy N Simhachalam , Reddy Nallala Amarendra , Rao A Kaleswara , Kumar Siddesh 
Published: June 2013

ABSTRACT

Aim
The present study was undertaken to determine the effect of denture cleansers on resiliency of soft liner.

Materials and methods
Two soft liners (Molloplast-B and Refit) and two denture cleansers (Clinsodent and Fittydent) were taken. Cylindrical aluminum dies were constructed of 12 mm length and 8 mm diameter at the ratio of 1.5:1. The samples are tested with Hounsfield tensometer.

Observation and results
Effect of both the denture cleansers on the lining materials was shown in the form of Graphs 1 and 2. The elastic recovery of Molloplast B in dry, Fittydent and Clinsodent is comparatively more than refit, but in control group the elastic recovery of both the material is almost equal.

Conclusion
Heat processed soft liners recover faster/better in a shorter time interval when compared to self-processed liners which takes longer time for the recovery. This time period is very important as the cushioning effect of the soft liner require an elastic recovery between the masticatory strokes.

Clinical implications
Greater the softness and better the elastic recovery of the denture soft liner, more effective would be its performance clinically. Silicon based material, such as Molloplast-B, rebounds quickly and would seem preferable to a material that is acrylic based. It is possible that, if the response is too slow or the elastic recovery is less, there may only be a partial recovery of the lining between the masticatory strokes. Progressive thinning of the lining materials might then occur resulting in a reduced cushioning effect.
Synthesis and Characterization of Strontium Bis(N-isopropylanilide) and Comparison with the Lighter Magnesium and Calcium Congeners
Authors: Loh Claas , Glock Carsten , Ziemann Steffen , Görls Helmar , Krieck Sven , Westerhausen Matthias 
Published: July 2013

Abstract
The metathesis reaction of strontium diiodide [(thf)5SrI2] with K[N(Ph)iPr] in THF yields [(thf)4Sr{N(Ph)iPr}2] (1). Ligand exchange reactions with 1,2-dimethoxyethane (DME), tetramethylethylenediamine (TMEDA), and pentamethyldiethylenetriamine (PMDETA) allow the isolation of the corresponding adducts [(dme)2Sr{N(Ph)iPr}2] (2), [(tmeda)(thf)Sr{N(Ph)iPr}2] (3) and [(pmdeta)Sr{N(Ph)iPr}2] (4), respectively. Magnesiation of N-isopropylaniline with dibutylmagnesium in THF leads to the formation of [(thf)2Mg{N(Ph)iPr}2] (5). A similar reaction in TMEDA gives nearly insoluble crystalline [(tmeda)Mg{N(Ph)iPr}2] (7), whereas the mother liquor contains heteroleptic [(tmeda)(nBu)Mg{N(Ph)iPr}] (6). Magnesiation of N-isopropylaniline in 2,2,5,5-tetramethyltetrahydrofuran (Me4thf) yields [(Me4thf)Mg{N(Ph)iPr}2] (8) with a threecoordinate metal center. In hydrocarbons this complex loses the bulky ether base, and the solvent-free dimer [Mg{N(Ph)iPr}2]2 (9) can be isolated. Reaction of this complex with 1,2- dimethoxyethane or metalation of N-isopropylaniline with dibutylmagnesium in DME yield the dme adduct, [(dme)Mg{N(Ph)iPr}2] (10). The crystal structures show that the nitrogen atoms of the magnesium-bound N-isopropylanilide ions are in planar environments whereas strontium-bound N-isopropylanilide ions show rather short contacts between the alkaline earth metal and the ipsocarbon atoms of the phenyl groups leading to a pyramidalization of the coordination of the nitrogen atoms
