Comparative Evaluation of Antibacterial Effect of Dental Luting Cements on Streptococcus mutans and Lactobacillus acidophilus: An in vitro Study
Authors: Khan S , Feroz SMA , Bhoyar A 
Published: July 2019

ABSTRACTIntroductionThis study aimed at evaluating and comparing the antibacterial activity of six types of dental luting cements onStreptococcus mutansandLactobacillus acidophilususing the agar diffusion test (ADT) and the direct-contact test (DCT). The antibacterial activity in ADT was measured based on the diameter of the zone of inhibition formed, whereas in DCT the density of the bacterial suspension was measured. The lower the density of the suspension, the more antibacterial activity the cement possesses.Materials and methodsAgar diffusion test was carried out on the bacteria. After an incubation period of 24 hours, the plates were checked for the presence of zone of inhibition. In DCT the cement was mixed and applied. Once the cement was set, bacterial suspension and brain–heart infusion medium was poured and incubated for 24 hours. After 24 hours, the plate was placed in the enzyme-linked immunosorbent assay plate reader, which measured the optical density of the fluid. The first set of data was recorded approximately 1 hour after incubation. Overall, three sets of data were recorded. Additional experiments were performed on set test materials that were allowed to age for 24 hours, 1 week, 1, 3, and 6 months.ResultsWhen using ADT only two cements zinc oxide eugenol (ZOE) and zinc polycarboxylate (ZPC) cement showed antibacterial activity against the test organisms. When using DCT, all cements showed some amount of antibacterial activity. Zinc oxide eugenol and ZPC cement showed highest amount of antibacterial activity againstS. mutansandL. acidophilusrespectively.ConclusionWithin the limitations of study, ZOE cement and ZPC cement were most effective against the tested microorganisms followed by the newer resin cement. The glass ionomer cement was the weakest of all.Clinical significancePatients with high caries index can be treated more effectively using the abovementioned cements.How to cite this articleFeroz SMA, Bhoyar A, Khan S.

Authors: Al-Samadani Khalid H 
Published: July 2019

ABSTRACT

Introduction
To assess the impact of using preventive mouthwash agents on the surface hardness of various resins composites.

Materials and methods
Hundred specimens were prepared from five types of composite resin material in a Teflon mold. Five specimens from each type of restorative materials (Herculite XRV Ultra, Estelite Σ Quick, Z Hermack, Versa Comp Sultan, and Empress Direct IPS) were evaluated posttreatment with immersion in four types of preventive mouthwashes gels and rinses – group 1: Flocare gel (0.4% stannous fluoride), group 2: Pascal gel (topical APF fluoride), group 3: Pro-relief mouthwash (Na fluoride), and group 4: Plax Soin mouthwash (Na fluoride) – at 37°C in a dark glass container at 24, 48, and 72 hours. Surface hardness measurement was made for each tested material. Statistically, we analyzed the mean values with one-way analysis of variance (ANOVA) and Tukey's test, with significance level of p < 0.05.

Results
All composite resin materials showed decrease in their surface hardness with the time elapsed (24, 48, and 72 hours) postimmersion in the preventive mouthwashes and gels except the Herculite XRV Ultra and Versa Comp Sultan materials. Flocare gel group showed increase in the surface hardness after 48 hours of immersion than the other periods and in Estelite Σ Quick after 72 hours. There was significant differences in all materials tested with the immersion in the preventive mouthwashes and gels, such as Flocare gel (0.4% stannous fluoride), Pro-relief mouthwash (Na fluoride), and Plax Soin mouthwash (Na fluoride) except Pascal gel (topical APF fluoride) (p > 0.05), at time intervals mentioned earlier (p < 0.05).

Conclusion
The effect of preventive mouthwashes and gels on resin composite materials was decreased surface hardness with the time elapse of immersion for all materials except the Flocare gel group, which contains 0.4% stannous fluoride as a preventive ingredient increases the surface hardness after 48 h for Herculite XRV Ultra and Versa Comp Sultan and Estelite Σ Quick after 72 hours.

Clinical significance
The preventive agents in the form of mouthwash and gel are used to prevent oral diseases that affect the surface hardness of composite resin, and this leads to occlusion, color stability, and surface roughness.

Published: July 2019

ABSTRACTIntroductionThe decalcification protocol of dentin surface with sodium hypochlorite removes the exposed collagen fibrils and could improve the longevity of the bonding interface. This study evaluated the influence of collagen removal with 10% sodium hypochlorite (10% NaOCl) on the longitudinal shear bond strength (SBS) of adhesives to dentin.Materials and methodsSeventy-two extracted human molars were sectioned and the buccal and lingual surfaces were flattened and acid etched with 37% phosphoric acid for 15 seconds. The specimens were divided into six groups (n = 12 teeth – 24 sections), according to adhesive and collagen removal protocol: group 1: UNO Dentastic; group 2: Prime and Bond NT; group 3: Single Bond; group 4: 10% NaOCl + UNO Dentastic; group 5: 10% NaOCl + Prime and Bond NT; group 6: 10% NaOCl + Single Bond. Composite Z100 buildup was prepared, and the SBS test was assessed after 24 hours and 1 year. Data were submitted to three-way analysis of variance (ANOVA) and Tukey tests (p < 0.05).ResultsThe mean values (MPa) were for 24 hours: G1: 22.45B; G2: 7.90DE; G3: 12.56CD; G4: 19.85BC; G5: 33.73A; G6: 20.77B; and for 1 year: G1: 2.43E; G2: 2.26E; G3: 4.3DE; G4: 18.79BC; G5: 26.49AB; G6: 22.73B.ConclusionDentin deproteinization treatment with 10% NaOCI influenced the SBS compared with conventional treatment. The negative influence on SBS detected for conventional groups at 1-year interval was not detected for deproteinized groups.Clinical relevanceThe longevity of hybrid layer is critical due to the hydrolysis process at the adhesive interface over time. The use of 10% NaOCl deproteinization protocol might improve the longevity of bonding in adhesive restorations.How to cite this articlePucci CR, Barbosa NR, Bresciani E, Yui KCK, Huhtala MFRL, Barcellos DC, Torres CRG.

Rebamipide to Manage Stomatopyrosis in Oral Submucous Fibrosis
Authors: Baptist Joanna , Shakya Shrijana 
Published: July 2019

ABSTRACT

Introduction
Oral submucous fibrosis (OSF) causes progressive debilitating symptoms, such as oral burning sensation (stomatopyrosis) and limited mouth opening. The standard of care (SOC) protocol includes habit cessation, intralesional steroid and hyaluronidase injections, and mouth opening exercises. The objective of the study was to evaluate efficacy of rebamipide in alleviating burning sensation of the oral mucosa in OSF in comparison with SOC intralesional steroid injections.

Materials and methods
Twenty OSF patients were divided into two groups [rebamipide (100 mg TID for 21 days) and betamethasone (4 mg/mL biweekly for 4 weeks)] of 10 each by random sampling. Burning sensation was assessed every week for 1 month. Burning sensation scores were analyzed using repeated measures analysis of variance (ANOVA) and paired t-test.

Results
Change in burning sensation score was significant (p < 0.05) in the first four visits. However, score between the 4th and 5th visit was not statistically significant (p > 0.05).

Conclusion
Our study has shown that rebamipide can be considered as an effective modality to manage burning sensation in patients suffering from OSF.

Clinical significance
Considering stomatopyrosis and trismus as a major cause for inability to eat in OSF, use of newer adjunctive modalities, such as rebamipide will ease patients suffering and also encourage them to consume food.

Authors: Tahmasbi Soodeh , Sheikh Tahereh , Hemmati Yasamin B 
Published: July 2019

ABSTRACTIntroductionTo investigate the galvanic corrosion of brackets manufactured by four different companies coupled with stainless steel (SS) or nickel–titanium (NiTi) wires in an artificial saliva solution.Materials and methodsA total of 24 mandibular central incisor Roth brackets of four different manufacturers (American Orthodontics, Dentaurum, Shinye, ORJ) were used in this experimental study. These brackets were immersed in artificial saliva along with SS or NiTi orthodontic wires (0.016”, round) for 28 days. The electric potential difference of each bracket/ wire coupled with a saturated calomel reference electrode was measured via a voltmeter and recorded constantly. Corrosion rate (CR) was calculated, and release of ions was measured with an atomic absorption spectrometer. Stereomicroscope was used to evaluate all samples. Then, samples with corrosion were further assessed by scanning electron microscope and energydispersive X-ray spectroscopy. Two-way analysis of variance was used to analyze data.ResultsAmong ions evaluated, release of nickel ions from Shinye brackets was significantly higher than that of other brackets. The mean potential difference was significantly lower in specimens containing a couple of Shinye brackets and SS wire compared with other specimens. No significant difference was observed in the mean CR of various groups (p>0.05). Microscopic evaluation showed corrosion in two samples only: Shinye bracket coupled with SS wire and American Orthodontics bracket coupled with NiTi wire.ConclusionShinye brackets coupled with SS wire showed more susceptibility to galvanic corrosion. There were no significant differences among specimens in terms of the CR or released ions except the release of Ni ions, which was higher in Shinye brackets.How to cite this articleTahmasbi S, Sheikh T, Hemmati YB.

Early Orthognathic Surgery: A Review
Authors: Alwadei Saleh 
Published: July 2019

ABSTRACT

Introduction
Management of growing patients with severe developmental jaw abnormalities can be very difficult. Early surgical intervention may be warranted in situations where function (e.g., mastication, swallowing, breathing, or speech) and/or psychological well-being could be negatively affected. Many surgeons and orthodontists are reluctant to recommend a surgical treatment option for growing patients with severe developmental jaw abnormalities because of their age. Specific surgical procedures can be performed during growth to correct developmental jaw abnormalities with predictable results. A sound understanding of the facial growth and the effects of the surgical procedures on subsequent growth is essential when managing growing patients with severe developmental jaw abnormalities. Children with severely progressive congenital deficiencies affecting function/health should be distinguished from ones with severe developmental jaw abnormalities that can be managed later in life. In this review, we will focus on the management of growing patients with developmental jaw abnormalities who seek orthodontic treatment, rather than patients with progressive congenital deformities affecting function and/or health.

Corneal Thickness after MyoRing Implantation for Keratoconus
Authors: Daxer Albert 
Published: July 2019

ABSTRACTPurposeTo analyze the corneal thickness development after MyoRing implantation as a tissue-related indicator of keratoconus progression.Materials and methodsTwelve eyes suffering from keratoconus were treated for visual rehabilitation by means of MyoRing implantation into a corneal pocket. The postoperative development of the corneal thickness at the thinnest point was analyzed. Follow-up ranged from 16 to 74 months (mean 37 months).ResultsOut of the 12 eyes only one eye showed a thinner cornea at the last follow-up 60 months after MyoRing implan-tation compared to the last preoperative data. None of these 12 eyes required an additional intervention like corneal cross-linking, explantation or keratoplasty. Four eyes showed even thickening of the cornea during the postoperative period.ConclusionMyoRing implantation for keratoconus does not only allow visual rehabilitation. It also seems to stop the progression of the disease by creating a new biomechanical equilibrium within the tissue which eliminates a constant stimulus that drives the vicious circle of progression.How to cite this articleDaxer A.

How to improve Visual Acuity after Intrastromal Corneal Ring Segments? Implantation for Keratoconus and Post-LASIK Ectasia
Authors: Barbara Ramez , Barbara Adel 
Published: July 2019

ABSTRACT
Keratoconus (KC) is an ecstatic corneal disease that causes irregular astigmatism which cannot be corrected by glasses, the irregular astigmatism causes loss of visual acuity (VA) both the uncorrected and the corrected VA, in addition to deterioration in the quality of vision. Contact lenses (CLs) improve the VA but cannot be tolerated in many cases due to several causes, such as loss of motivation, atopic and allergic conjunctivitis that are more frequently associated with KC and dry eyes. Intrastromal corneal ring segments implanted in keratoconic eyes improve uncorrected visual acuity (UCVA), best spectacle corrected visual acuity (BSCVA), reduce myopia, astigmatism, high order aberrations (HOA) and regularizes the cornea (less irregular astigmatism), similar results are achieved in the treatment of post-LASIK and post PRK ectasia. These results were confirmed in long-term follow-up. The more advanced the KC the more is the effect of the ICRS but the less the functional VA achieved and vice versa. Thicker rings are more effective, and the smaller the optical zone the more is the effect of the ICRS. The aim of ICRS implantation in KC is not to be free of glasses or CL but to enable the patient of seeing with glasses or to tolerate CL in order to prevent or delay the need for penetrating keratoplasty (PKP) or deep anterior lamellar keratoplasty (DALK). In many cases, we can achieve a functional and satisfactory UCVA with no need for glasses and this is the case in nonadvanced KC but not in the advanced cases. In some cases, the results achieved need additional means to improve VA in order to get satisfactory VA. There are nonsurgical and surgical means to improve VA after ICRS, these means will be reviewed in this article.

Authors: Zadok David , Avni Isaac , Bakshi Erez , Barequet Irina S , Aizenman Isaac , Levinger Samuel 
Published: July 2019

ABSTRACT

Purpose
To report refractive, topographic and safety outcomes of corneal cross-linking (CXL) in patients younger than 18 years of age with progressive keratoconus.

Materials and methods
In this retrospective study, we enrolled 31 eyes of 21 children aged 11 to 17 years that underwent corneal riboflavin-ultraviolet A induced CXL due to progressive keratoconus at three different ophthalmology departments in Israel. They were followed for 3 to 48 months (average 23 ± 13.6 months). Evaluated parameters were uncorrected visual acuity (UCVA), best spectacle corrected visual acuity (BSCVA), manifest refraction, pachymetry, slit- lamp examination and corneal topography at baseline and at 1,3,6,12,24 and 48 months.

Results
We found a nonsignificant improvement in UCVA and BSCVA with a small reduction of manifest cylinder and no significant change in spherical equivalent or K-values. Following CXL, stability of UCVA and BSCVA at the last follow-up examination was found in 71 and 77% of treated eyes, respectively. No permanent adverse events have been recorded throughout the study period.

Conclusion
In our series, CXL was a safe procedure in the pediatric population. Stabilization of progressive keratoconus was achieved in visual acuity, refractive and topography parameters with no improvement in corneal indices in contrary to adult CXL treatment.

Collagen Cross-linking for Pellucid Marginal Degeneration
Authors: MacGregor Cheryl , Jayaswal Rakesh , Maycock Nick 
Published: July 2019

ABSTRACT
Pellucid marginal degeneration (PMD) is a rare progressive condition resulting in inferior corneal thinning and astigmatism. Alongside keratoconus and keratoglobus, it is considered one of noninflammatory corneal ectasias. The focus of corneal thinning is greatest inferiorly resulting in diminished visual acuity and overall reduction in visual quality. Traditional methods of treatment or disease management have been similar to those proposed for keratoconus, contact lenses, escalating to intrastromal rings, lamellar keratoplasty or penetrating keratoplasty.
Collagen cross-linking (CXL) has steadily gained acceptance as the treatment of choice for progressive corneal ectasias. Although it has been described at length for keratoconus, there is little literature describing or advocating its use in PMD. In this article, we will review the evidence for CXL and its use in PMD.

Pathogenesis of Fixed Dilated Pupil (Urrets-Zavalía Syndrome) after Deep Lamellar Keratoplasty in Keratoconus
Authors: Reis José RC , Diniz-Filho Alberto , Rocha Fábio M 
Published: July 2019

ABSTRACTPurposeTo present a case series of patients that developed Urrets-Zavalia syndrome (UZS) after deep anterior lamellar keratoplasty (DALK) for treating keratoconus and discuss the mechanisms for the syndrome.Materials and methodsRetrospective chart analysis of patients who developed UZS after DALK at the Cornea Unit, Hospital São Geraldo, Federal University of Minas Gerais.ResultsWe present a series of 3 patients with features consistent with UZS, after undergoing DALK. Elevated intraocular pressure (IOP) was noted in the early postoperative period in 2 cases, despite the fact that the other case reported eye pain, headache, and nausea at the night after the surgery with undocumented IOP. Although at different extents, the pupil remained atrophic and dilated in all 3 eyes, and 2 of them developed anterior subcapsular cataract.ConclusionIris ischemia resulting from occlusion of iris root vessels due to elevated IOP higher than diastolic blood pressure causes UZS. Elevated IOP should be monitored, especially in young patients with low diastolic blood pressure, in order to avoid the occurrence of the syndrome.How to cite this articleReis JRC, Diniz-Filho A, Rocha FM, Torquetti L.

Authors: Sandhu Jaspal Singh , Singh Amrinder , Arvind Deepchand Nigam 
Published: July 2019

ABSTRACT

Purpose
Recent sprint training regimens have used high-speed incline treadmill running to provide enhanced loading of muscles responsible for increasing forward running speed. The purpose of this study was to determine the standard alterations in the lower-limb joint kinematics and gait parameters resulting from changes in treadmill slope during the use of the treadmill as a medical reference.

Subjects
The subjects of this study were 20 normal, healthy elite football players without any orthopedic, respiratory, or cardiovascular system problems.

Materials and methods
The running gait of subjects was analyzed using motion analysis system on an inclined treadmill with three running trials, each for 3 minutes. The gait was measured at incline of 0, 9, and 18%. The speed of the treadmill was fixed at 4.0 m/s in order to maintain a constant running speed.

Results
The subjects’ gait parameters were observed to change significantly between slopes of 0 and 18%. The results showed greater maximum knee flexion, ankle dorsiflexion, and total hip range of motion (ROM) in incline treadmill running compared to level running.

Conclusion
The results of this study can be put in as a predesigned rehabilitation program for sprint training on a treadmill, especially for treadmills with adjustable gradients.
