Published: July 2019

ABSTRACT

Introduction
Various bulk-fill materials depending on their composition, viscosity, and flow ability have different physical and mechanical properties. The aim of this in vitro study was to determine and compare the shear bond strength and microleakage properties of activa restorative with other bulk-fill restorative materials surefil (SDR), Biodentine, ever X posterior.

Materials and methods
Forty permanent premolars were selected for shear bond strength, and 20 permanent premolars were selected with class II cavities on mesial and distal side for microleakage. Universal testing device was used to assess the shear bond strength. Microleakage was checked using dye penetration method under a stereomicroscope. Mean and standard deviation values were calculated from the recorded values. Intergroup comparison was done by one-way analysis of variance (ANOVA) followed by pairwise comparison using Tukey honestly significant difference (HSD) post hoc test.

Results
The mean shear bond strength was highest for SDR surefil followed by Ever X posterior, Bioactive restorative, and Biodentine respectively. In this study, SDR (surefil) showed better shear bond strength and better microleakage properties compared with the other test materials (F = 186.7157, p < 0.05).

Conclusion
The result of this study showed that flowable and fiber-reinforced composites have better shear bond strength and microleakage properties.

Clinical significance
Flowable bulk-fill composite resins can be used as dentin substitutes because of its superior properties.

ABSTRACT

Introduction
The aim of this study is to evaluate the effect of different combinations of various surface treatments on the shear bond strength (SBS) of repaired composite resin.

Materials and methods
A total of 122 composite samples were prepared from Filtek Z350 XT. Samples were light cured and stored for 6 weeks. Surface treatment of old composite was done in five groups: Group I: bur roughening + phosphoric acid etching, group II: bur roughening + hydrofluoric acid etching + silane coupling agent, group II: air abrasion + phosphoric acid etching, group IV: air abrasion + phosphoric acid etching + silane coupling agent, group V: air abrasion + hydrofluoric acid etching + silane coupling agent. Bonding agent was applied to all surface-treated old composites and light cured. The fresh composite resin was bonded to treated surfaces and cured and stored in water at 37°C for 6 weeks. Shear bond strength was measured by a universal testing machine.

Results
Shear bond strength values of all groups were not statistically significant except for group V, which showed statistically significant higher SBS than group III.

Conclusion
Techniques with readily available materials at the clinic can attain similar SBS to more elaborate technique involving potentially hazardous materials.

Published: July 2019

ABSTRACT

Introduction
The purpose of this study was to compare the oral health status and its effect on the oral health-related quality of life (OHRQoL) of hospitalized and nonhospitalized elderly patients in a single community. The null hypothesis for the study states that there is no difference in the oral health status and OHRQoL between hospitalized and nonhospitalized elderly patients.

Materials and methods
This study was conducted at the King Khalid Hospital and College of Dentistry, King Saud University, Riyadh, Kingdom of Saudi Arabia. A total of 99 (43 – hospitalized and 56 – nonhospitalized) geriatric patients participated in this study. Oral health-related quality of life was estimated using the geriatric oral health assessment index questionnaire. Decayed, missing, and filled teeth (DMFT) index and plaque index were used to assess the oral health status of the study participants.

Results
The mean age of the study participants was 68.2 years; 17.2% were females and 82.8% were males. There was no significant difference between hospitalized and nonhospitalized patients in OHRQoL and DMFT index. However, the oral hygiene status was better among nonhospitalized patients as compared with hospitalized patients.

Conclusion
There was a significant difference in the oral hygiene status between hospitalized and nonhospitalized geriatric patients.

Clinical significance
Caregivers must be sensitized to the importance of oral health for the elderly population, and oral health should be considered an integral component of general health.

Authors: Izquierdo Luis , Henriquez Maria A , Dañin David 
Published: July 2019

ABSTRACT

Purpose
To compare corneal elevation values in normal eyes, forme fruste keratoconus (FFKC) and different stages of keratoconus using Scheimpflug imaging.

Materials and methods
This prospective, comparative study included 267 eyes (107 normal eyes, 21 FFKC and 139 keratoconus). Keratoconic eyes were divided into four groups according to keratometry values. Maximum posterior elevation (PE) above the (best fit sphere (BFS) at the central 5 mm were measured using the Pentacam (Oculus Optikgeräte GmbH). Receiver operating characteristic curves were used to determine the test's overall predictive accuracy and to identify optimal cutoff points to discriminate between the groups.

Results
PE had the smallest values in normal eyes and increased in FFKC and each progressive stage of keratoconus. Mean PE was 9.98 ± 5.33 µm in normal eyes, 18.09 ± 9.23 µm in FFKC and 24.97 µm ± 15.89, 37.82 ± 18.64, 46.82 ± 21.41 and 66.07 ± 39.09, in keratoconus stage I, II, III and IV respectively.

Conclusion
Posterior elevation values increased according to the severity of keratoconus disease. PE can be used as indicator of keratoconus progression.

Published: July 2019

ABSTRACT
To describe the long-term result of the Athens protocol (custom topography-guided advanced surface ablation followed by riboflavin-UVA collagen cross-linking in the same day) for progressive advanced keratoconus in the left eye, while the fellow right eye first presented with relatively mild keratoconus that was treated with a more conservative therapeutic approach of continuous contact lenses use with the goal for ectasia stabilization. Five years after the Athens protocol, a regression of over 10D (diopters) was observed on the sagittal curvature with significant regularization of corneal shape and improvement of distance corrected visual acuity (DCVA) in the left eye. The right eye, which was treated more conservatively, had an over 12D increase on sagittal curvature along with significant distortion of the corneal shape and reduction of DCVA.

Authors: O’Brart PS David , Patel Parul , O’Brart Naomi A 
Published: July 2019

ABSTRACT

Aims
To determine the long-term efficacy and safety of riboflavin/ultraviolet a corneal cross-linking (CXL) to halt the progression of keratoconus.

Materials and methods
Thirty-five patients (35 eyes) who had undergone CXL with epithelial removal 5 or more years previously were examined.

Results
At 5 years, mean spherical equivalent (SEQ) increased by 0.78 diopters (D) (p < 0.001), mean simulated K (Sim K) reduced by 0.86D (p < 0.00001), cone apex power (CAP) reduced by 1.1D (p < 0.0002) and root mean square (RMS) (p < 0.0001), coma (p < 0.0001), and secondary astigmatism (p < 0.001) decreased compared to preoperative values. Compared to values at 1 year, mean refractive cylinder reduced by 0.26D (p < 0.05), mean Sim K reduced by 0.46D (p < 0.0005), CAP reduced by 0.81D (p < 0.01), RMS (p < 0.001), coma (p < 0.002) and secondary astigmatism (p < 0.02) reduced and central pachymetry increased (p < 0.05) at 5 years. No treated eyes showed evidence of progression at 5 years. None lost >1 line of CDVA. Eight untreated fellow eyes progressed during the follow-up period and underwent CXL.

Conclusions
Corneal cross-linking is an effective treatment to halt the progression of keratoconus at 5 years, with no sight-threatening complications. Improvements in topographic and wave-front indices present at 1 year continue to improve at 5 years.

Phakic Intraocular Lenses in Keratoconus
Authors: Alio Jorge L , Sanz-Díez Pablo 
Published: July 2019

ABSTRACT

Purpose
To discuss and summarize the indications, contraindications and results in refractive surgery for keratoconus.

Summary
Keratoconus is an ectatic corneal disease characterized by a progressive corneal thinning and irregular astigmatism that negatively impact in the visual function and the optical quality of the patients. The refractive surgery in keratoconus has been discussed by several authors. The two primary lines of action are phakic lens implantation and corneal tissue ablation using photorefractive keratectomy. The use of phakic intraocular lenses (IOLs) to correct myopia and compound myopic astigmatism associated with keratoconus is gaining popularity.

Recent findings
The use of phakic IOLs to correct myopia and compound myopic astigmatism associated with keratoconus is gaining popularity. According to a recent study by our group the safety of this procedure in visual terms is high (post-CDVA/ pre-CDVA = 1.19 ± 0.29). It is also an effective operation (post-UDVA/pre-CDVA = 0.90 ± 0.26).

Effect of Circular Keratotomy on Progression of Keratoconus
Authors: Krumeich Jörg H , Hirnschall Nino 
Published: July 2019

ABSTRACT

Purpose
Studies on keratoconus treatment with regard to the stage of the disease have not been published. We evaluated patient outcomes over a 5-year period after circular keratotomy (CKT) to treat stage I and II progressive keratoconus.

Setting
Clinic Krumeich, Bochum, Germany.

Design
Retrospective clinical study.

Materials and methods
We retrospectively evaluated the outcomes of 185 consecutive CKT procedures to treat early, progressing keratoconus. A 7-mm trephine incision, with a depth that was 90% of the thinnest pachymetry value but not less than 400 µm, was made with the guided trephine system concentric to the pupil and sutured with a double running anti-torque suture. Keratometry readings and astigmatism measurements at 1-year postsurgery were compared with values obtained at 3 and 5 years postsurgery. Preoperative values of best-corrected visual acuity with glasses were compared with values obtained at 3 and 5 years postsurgery. Statistical analyses for significance were performed.

Results
Keratometric readings revealed stability at 5 years postsurgery in 84.3% (n= 51) of those eyes for which all values at all time points were available. Likewise, astigmatism values revealed stability in 92.2% of eyes. Best-corrected visual acuity improved significantly from preoperative to 5 years in 73.68% (n = 38). Best-corrected visual acuity did not change in 18.42% (n = 36).

Conclusion
Circular keratotomy halted the progression of early-stage keratoconus for at least 5 years in 84.3% of the eyes studied. The stable keratometric results suggest that CKT treatment should be considered for patients diagnosed early in the progression of this disease.

Published: July 2019

ABSTRACTBackground and objectiveMicroleakage of restored teeth can be considered as a major contributing factor for the occurrence of tooth discoloration, secondary caries, deterioration of restorative material, postoperative tooth sensitivity, and pulpal irritation. The objective of this study was to compare the microleakage of primary molars restored with conventional glassionomer cement (GIC) and Giomer after caries removal using conventional cavity preparation (CCP) and chemo-mechanical caries removal (CMCR) techniques.Materials and MethodsSixty extracted carious human primary molars were randomly assigned into three groups of 20 each based on the method of caries removal: Group A: CCP technique; group B: CMCR using Papacarie gel; and group C: CMCR using Carisolv gel. Each group was further divided into two of 10 teeth each according to the restorative material used – conventional GIC (Fuji II) and Giomer (Beautifil II). The restored teeth were thermocycled, immersed in methylene blue dye, sectioned, and examined under stereomicroscope to elicit the dye penetration scores.ResultsThe results demonstrated that none of the restorative materials were free from microleakage. In Fuji II samples highest microleakage scores were noticed in group A (2.09) followed by group B (0.64), and least in group C (0.27), which were statistically significant. However, in Giomer samples no statistical significant difference in microleakage scores was noticed among the three groups.ConclusionChemo-mechanical caries removal technique showed less microleakage when compared to CCP technique and the marginal sealing ability of Giomer was superior to conventional GIC.How to cite this articleSankar AJS, Birra C, Bandi S, Chinta M, Enuganti S, Mukthineni S.

ABSTRACTLipomas are most common, benign, soft tissue tumors in the body; however, they are rarely seen in the oral cavity. Intraoral lipomas are seen as benign, well-encapsulated swelling without pain with added yellowish tinge. We are presenting a case of an intraoral lipoma where the 22-year-old female presented a single well-encapsulated swelling in the posterior aspect of the palate on left side. The purpose of this report is to emphasize the need for dentists to be aware of frequency of occurrence of intraoral lipoma.How to cite this articleMunde PT, Munde PB, Jadhav P.

Giant Aneurysmal Bone Cyst of the Mandible
Authors: Gurav Rajshri U 
Published: July 2019

ABSTRACTAn aneurysmal bone cyst (ABC) is a benign osteolytic bony lesion that commonly affects the long bones with rare presentation in the jaws. The etiopathogenesis of ABC is unsure. Several theories have been suggested like trauma, intramedullary hematoma, alterations in local hemodynamics, reactive malformation, and genetic predisposition. Though ABCs are considered as secondary phenomenon in preexisting benign and malignant bony lesions, intermittent reports of ABCs with primary/denovo origin are generating perplexity in the scenario.Here, we describe a rare case of giant ABC involving mandible extending from right angle of mandible to left canine region which crosses midline, in a 10-year-old female patient, without any evidence of preexisting bony lesion.How to cite this articleGurav RU, Pathak J, Patel S, Swain N.

Comparison of the Effects of Three Different Nickel–titanium Rotary Instruments on the Fracture Resistance of Obturated Roots: An in vitro Study
Authors: Shenoy Vanitha U , Pawar Ritesh B , MV Sumanthini , Shaikh Saimanaaz AH 
Published: July 2019

ABSTRACTAimThe aim of the article is to compare the effects of three different nickel–titanium (NiTi) rotary instruments on the fracture resistance of obturated roots.Materials and methodsA total of 100 permanent mandibular premolars were randomly divided into four groups of 25 teeth each and biomechanical preparation was done: group I: stainless steel K-hand files (HFs), group II: ProTaper NiTi instruments (PT), group III: HyFlex CM NiTi instruments (HCM), and group IV: K3XF NiTi instruments. Following root canal preparation, the canals were obturated using lateral condensation. A light body silicone impression material was used to simulate the periodontal ligament (PDL). Fracture resistance was tested in an Instron testing machine.Statistical analysisData were analyzed with Kruskal–Wallis test.ResultsThere was no difference in significance (p < 0.05) among the different groups tested with respect to their fracture resistances.ConclusionThe present study concluded that rotary instrumentation could result in an increased chance for dentinal defects as compared with hand instrumentation. Greater taper rotary NiTi instruments do not increase the fracture susceptibility of roots, which in turn depends on various factors other than instrumentation alone.Clinical significanceGreater taper achieved by rotary NiTi files during canal preparation facilitates efficient irrigation and complete debridement. Root fracture might occur as a result of microcracks or craze lines that propagate with repeated stress application by occlusal forces and also during canal preparation. Based on the results obtained, it can be decided whether the use of the newer rotary NiTi system contributes to endodontic success and long-term survival of endodontically treated teeth.How to cite this articleShaikh SAH, Shenoy VU, Sumanthini MV, Pawar RB.

Published: July 2019

ABSTRACTIntroductionVarious chemical agents are being used as an adjunct to mechanical therapy. Chlorhexidine (CHX), though considered as the gold standard, has certain side effects. The use of herbal products as an adjunctive therapy is thus gaining more popularity. The aim of this study was to evaluate the antimicrobial and anti-inflammatory efficacies of two commercially available mouthwashes.Materials and methodsAntimicrobial activity of the mouthwashes was analyzedin vitroby evaluating their minimal inhibitory concentration (MIC) against four microorganisms. The anti-inflammatory efficacy was evaluated in 84 individuals, who were divided into four groups of 21 each based on their gingival index (GI) score. The subjects used the respective mouthwashes allotted to them for 2 weeks. Plaque index (PI), GI, and modified sulcus bleeding index (mSBI) of the participants were recorded at baseline and 14 days.ResultsThe herbal mouthwash was effective against the tested organismsin vitro. The PI and GI scores reduced in all the four groups at the end of 14 days with the CHX group showing more reduction. The herbal mouthwash showed significantly better clinical outcomes when compared with other groups and results comparable to CHX.ConclusionThe herbal mouthwash showed antimicrobial and anti-inflammatory effects comparable with that of 0.2% CHX, and may have a potential as an adjunct to scaling and root planing.How to cite this articleThakur S, Malagi S, Acharya AB.
