Published: July 2019

AbstractPurposeExcept for the occasional case report, there are no studies evaluating the success rate of osseointegrated dental implants in individuals infected with the human immunodeficiency virus (HIV). This study investigated the short-term clinical outcome of implant placement in a group of HIV-positive and HIV-negative individuals who required complete dentures.Methods and MaterialsEdentulous subjects were recruited from an HIV-dedicated clinic and a dental school clinic. Two BioHorizons® dental implants were placed in the anterior mandible to support an overdenture opposing a maxillary denture. Outcome measurements obtained six months after activation of implants were presence of pain, mobility, soft tissue status, and radiographic bone level. Descriptive statistics were used.ResultsTwenty-nine edentulous adults, including 20 HIV-positive subjects (test) and nine HIV-negative subjects (control), participated. The test group had six females, 14 males; 13 Whites, four African-Americans, and three Hispanics with a mean age of 48.9 years (range: 35-59). The mean CD4 count was 467 cells/mm3 (range: 132-948). The control group had six females, three males; seven Whites, and two Hispanics with a mean age of 65.3 years (range: 50-82). Short-term success rate was 100% for both groups. No difference in clinical outcome was found between the groups.ConclusionThis study demonstrated dental implants are well tolerated and have predictable outcomes for HIV-infected individuals for the duration of the study and probably over an even longer term.CitationStevenson GC, Riano PC, Moretti AJ, Nichols CM, Engelmeier RL, Flaitz CM.

Authors: Ambrosano Gláucia Maria Bovi , Cavalcante Larissa Maria Assad , Peris Alessandra Resende , Ritter André Vicente , Pimenta Luiz André Freire 
Published: July 2019

Abstract

Aim
The aim of this study was to evaluate the influence of four photoactivation systems [quartz tungsten halogen (QTH), light-emitting diode (LED), argon ion laser (AL), and plasma arc curing PAC)] on cementum/ dentin and enamel microleakage of Class II restorations using a microhybrid [Z250 – 3M ESPE] and two packable composites [(SureFil - Dentsply and Tetric Ceram HB – Ivoclair/Vivadent].

Methods and Materials
Three hundred sixty “vertical-slot Class II cavities” were prepared at the mesial surface of bovine incisors using a 245 carbide bur in a highspeed handpiece. Specimens were divided into twelve groups (composite-photoactivation systems). Half of the specimens had the gingival margin placed in enamel (n=15) and the other half in cementum/dentin (n=15). Composites were inserted and cured in 2 mm increments according to manufacturers’ recommended exposure times. After polishing, the samples were immersed in 2% methylene blue solution, sectioned, and evaluated at the gingival margins. Data were submitted to statistical analysis using the Kruskal–Wallis and Mann-Whitney tests.

Results
No significant differences were found among the photoactivation systems and among resin composites (p>0.05). Microleakage was not significantly affected by location (enamel vs. cementum/dentin, p>0.05). These findings suggested neither the photoactivation systems nor the resin composite types might have an effect on the microleakage at gingival margins Class II cavities.

Surface Roughness and Adherence of Candida Albicans on Soft Lining Materials as Influenced by Accelerated Aging
Authors: Tari Banu Filiz , Nalbant Dilek , Dogruman Al Funda , Kustimur Semra 
Published: July 2019

Abstract

Aim
Candida albicans (C. albicans) has been widely associated with the etiology of denture-related stomatitis and has been found on soft denture lining materials. The aim of this study was to examine the surface roughness and adherence of C. albicans to saliva coated and non-coated soft lining materials by subjecting them to an in vitro accelerated aging test.

Methods and Materials
Samples were prepared from three soft lining materials (Visco Gel, Ufi Gel P, Molloplast B). Surface roughness measurements and adhesion of C. albicans were examined before and after an aging process. The stimulated human whole saliva was used to assess its effect on adhesion.

Results
The aging process promotes the surface roughness of soft lining materials. The aging surface roughness of Visco Gel was significantly higher than Ufi Gel P and Molloplast B. No significant difference was observed between non-aged and uncoated materials, but aged and uncoated soft lining materials showed a greater adherence of C. albicans. No significant difference was observed between non-aged and saliva coated materials, but aged and saliva coated soft lining materials showed a greater adherence of C. albicans.

Conclusions
Candidosis induced by C. albicans is the most common fungal infection. Awareness of susceptibility of soft lining materials to the adherence of C. albicans is an important factor in their selection. The use of soft lining materials with smooth surfaces minimizes the adherence of C. albicans.

A Comparative Evaluation of the Effectiveness of an Anorganic Bone Matrix/Cell Binding Peptide with an Open Flap Debridement in Human Infrabony Defects: A Clinical and Radiographic Study
Authors: Bhongade Manohar L. , Tiwari Ishan R. 
Published: July 2019

Abstract

Aim
The development of biologic modalities designed to enhance bone regeneration and wound healing of specific periodontal sites continues to unfold. This is accomplished through the cell binding activity of Type-I collagen provided by a synthetic cell binding peptide (P-15) which is incorporated in a scaffold of anorganic bovine matrix (ABM). This combination is designed to facilitate the attachment, migration, and differentiation of cells. The objective of this study is to clinically and radiographically evaluate the effectiveness of the combination of ABM and P-15 (ABM/P-15) ‘putty’ during regenerative periodontal procedures.

Methods and Materials
A total of 20 interproximal intraosseous defects in 16 patients, (8 males, 8 females), age 22-48 years (mean 34.45) were recruited and divided equally into two experimental groups. Following open flap debridement (OFD), the defect sites in a test group were grafted with a bovine-derived xenograft enriched with a cell binding peptide. The defect sites in a control group were treated with only OFD. Appropriate periodontal maintenance schedules were followed; at six months, clinical and radiographic assessments for soft tissue and hard tissue were performed for documentation and finalization of results.

Results
Statistical analysis using student paired ‘t’ test analyses of the patient mean value from the 16 patients revealed the ABM/P-15 ‘putty’ graft group demonstrated significantly better mean defect fill of 3.4 + 0.7 mm (70.5%) versus mean defect fill of 0.9 mm (17.33%) for defects treated with only OFD. Soft tissue findings showed significant differences among treatment with ABM/P-15 compared to OFD.

Conclusions
These results indicate the use of P-15 synthetic cell binding peptide combined with ABM yields better clinical results in conjunction with OFD than with OFD alone.

Influence of Kinetic Cavity Preparation Devices on Dental Topography: An in vitro Study
Authors: Maia Lucianne Cople , Antunes Livia Azeredo A. , Vieira Áurea Simone Barrôso , dos Santos Márcia Peraira Alves 
Published: July 2019

Abstract

Aim
The objectives of this study were to assess the influence of four different kinetic cavity preparation devices on cavity preparation taking into account tip angulation, internal tip diameter, and distance to the dental substrate. The dental topography itself was also evaluated after the use of these devices.

Methods and Materials
Quantitative parameters using pertinent statistical tests as well as qualitative parameters were used to assess the topography in terms of the dispersion halo effect (DHE), size, and depth of the preparation.

Results
The DHE did not present differences among the groups. In relation to the preparation size, the internal diameter influenced 120° point angles, whereas distance influenced the 90° ones. Considering the preparation depth, the 90° point angle yielded the deepest. In the qualitative analysis, both angles provided cavity preparations with rounded cavosurface angles. The 120° point angles yielded inclined, shallow V-shaped preparations, whereas the 90° angles presented U-shaped preparations reaching the dentin. The enamel had an irregular aspect and exposed prisms; dentin had a loose smear layer with aluminum oxide residues.

Conclusion
The kind of device may influence the kinetic cavity design.

Clinical Significance
It is the clinician that knows how to select the appropriate devices to adopt in order to achieve the desired cut, depth, and shape of cavity preparations.

Authors: Flório Flávia Martão , Barbosa Cinthia Maria , Sasaki Robson Tetsuo , Basting Robera Tarkany 
Published: July 2019

Abstract

Aim
The aim of this in vitro study was to evaluate the influence of time after treatment with a 35% hydrogen peroxide bleaching agent on the shear bond strength between composite resin and sound enamel and dentin.

Methods and Materials
Eighty dental slabs - 40 enamel (E) slabs and 40 dentin (D) slabs - were embedded, flatted, and divided into four groups (n=10). In G1 the E and D slabs were kept in artificial saliva for 14 days. For the G2, G3, and G4 groups the E and D slabs were submitted to bleaching treatment with a 35% hydrogen peroxide bleaching agent. At different times after bleaching treatments (G2=immediate; G3=seven days; G4= fourteen days), composite resin cylinders were made using an adhesive system. Tests were performed in a universal testing machine at a speed of 0.5 mm/min to obtain the values in MPa.

Results
For enamel, the Kruskal-Wallis test and Dunn Method showed G1 differed significantly from G2 (G1=13.40 a; G2=6.64 b; G3=16.76 a; G4=11.64 ab). For dentin, the analysis of variance (ANOVA) and Tukey tests showed that G1 differed significantly from G2 and G3 (G1=12.11 a; G2=4.97 b; G3=8.67 c; G4=11.86 ac).

Conclusion
It is recommended adhesive restorative procedures in enamel be delayed for seven days postbleaching treatment with 35% hydrogen peroxide, while restorations in dentin should be delayed for 14 days following bleaching treatment.

Short-term Evaluation of Resin Sealing and Rebonding on Amalgam Microleakage: An SEM Observation
Authors: Moosavi Horieh , Sadeghi Samaneh 
Published: July 2019

Abstract

Aims
The aim of this study was to evaluate the effect of two different sealing agents on the microleakage of Class V amalgam restorations with and without resin rebonding.

Methods and Materials
Sixty extracted premolars were divided into six groups with ten teeth in each group. Class V cavity preparations were prepared on the facial surfaces of each tooth with the coronal margins placed in enamel and apical margins in cementum (dentin). The preparations in three groups were treated with Copalite, Scotchbond Multi-Purpose (SBMP), and no sealing agent, respectively. The other three groups received the same sealing agents in conjunction with a rebonding process. This arrangement of specimens provided for a comparison of the groups with and without a rebonding procedure. Amalgam was used as the restorative material. Specimens were thermocycled, stained, and sectioned. Microleakage was graded (0-3) using a stereomicroscope at 40x magnification. A scanning electron microscope (SEM) was used along with a high resolution elemental analysis. Data were analyzed with Kruskal-Wallis, Mann-Withney, and Wilcoxon pair wise statistical tests (α=.05).

Results
The bonded amalgam groups demonstrated significantly less microleakage, whereas the unsealed groups showed the highest microleakage (P=0.001). A significant difference between the mean rank of the microleakage of enamel and dentin margins was observed (P=0.037). Insignificant, lower microleakage was observed in groups receiving a rebonding procedure (P=0.085).

Conclusion
Copalite and a multi-step adhesive system had a significant effect on microleakage of Class V amalgam restorations. The influence of the multi-step adhesive system was significantly greater than Copalite. The rebonding of the amalgam restorations did not have a significant effect on microleakage.

Authors: Tinaz Ali Cemal , Kivanç Baǧdagül Helvaciölu , Gürgül Güliz 
Published: July 2019

Abstract

Aim
The focus of this study was to examine the staining potential of calcium hydroxide (Ca(OH)2) on tooth structure following the removal of AH26 root canal sealer.

Methods and Materials
Fifty maxillary anterior teeth were prepared and obturated with AH26 and gutta percha. The sealers were then removed 24 hours later and the teeth were randomly divided into two groups. Ca(OH)2 was then placed in the root canals of the first group of teeth as a medicament and camphorated monochlorophenol (CMCP) was placed in the second group of teeth after the filling material was removed. The color of the external tooth surfaces was determined before tooth preparation and two weeks after the placement of the medicaments. The Z test was used for statistical analysis.

Results
All experimental teeth showed varying degrees of coronal discoloration with the Ca(OH)2 group showing more discoloration than the CMCP group (p<0.05).

Conclusion
Using Ca(OH)2 as a medicament after removing AH26 caused progressive discoloration of the teeth, whereas using CMCP caused only slight discoloration.

Clinical Significance
To avoid staining of the treated tooth, AH26 root canal sealer must be completely removed from the dentin walls before using a medicament.

A Comparative in vitro Study of the Load at Fracture of All-ceramic Crowns with Various Thicknesses of In-Ceram Core
Authors: Turkyilmaz Ilser , Gokce Suat , Celik-Bagci Emine 
Published: July 2019

Abstract

Aim
The aim of this study was to investigate the influence of three different thicknesses of In-Ceram core on the load at fracture of all-ceramic crowns.

Methods and Materials
Thirty standardized crown-shaped nickel-chromium alloy dies were fabricated using a milling machine. Twenty dies were prepared with a 1 mm shoulder for Groups A and B. The only difference in the ten dies used for Group C was a smaller 0.5 mm lingual shoulder. The thicknesses of In-Ceram were 0.5 mm, 1.5 mm, and 0.75 mm for Groups A, B, and C. All all-ceramic crowns were fabricated in accordance with the manufacturer's instructions. After cementation of the crowns, their fracture resistance was tested with a universal testing machine. The load was directed to a point located 3 mm from the lingual aspect of the incisal edge at 30 degrees to the long axis of each specimen until catastrophic failure occurred.

Results
The mean loads at fracture for Groups A, B, and C were 1117±388 N, 2083±385 N, and 1439±368 N, respectively. No statistically significant difference in load at fracture between Groups A and C was found (p>0.05). However, the differences were statistically significant between Groups A and B (p<0.001) and Groups B and C (p<0.001).

Conclusion
Under the guidelines of this study, increasing the thickness of the In-Ceram core increased the fracture resistance of the all-ceramic crowns.

Clinical Significance
The sufficient thickness of the In-Ceram core of all-ceramic crowns is an important factor in fracture resistance. Therefore, dental practitioners should be careful in patient selection; if the horizontal overlap of a tooth to be restored is too limited, then all-ceramic crowns may not be a feasible option.

Published: July 2019

AbstractAimThe aim of this study was to assess the frequency of nine tongue conditions and evaluate their relationship to oral hygiene status and personal habits in a Northern Iranian population.Methods and MaterialsThis descriptive study evaluated 1901 healthy subjects (1142 women, 759 men) >12 years who were referred to the Dental Faculty of Babol University during a period from February 2005 to July 2006. A questionnaire was designed according to the aims of the study. Each subject completed the questionnaire and received a complete dental and oral examination. Statistical analysis was performed using SPSS software and Chi-square and Fisher's exact probability tests.ResultsSix hundred seventy-two (35.3%) of 1901 subjects had tongue lesions with a frequency of 38.6% in women and 47.7% in men which was statistically significant (P<0.0001). A strong association was found between tongue lesions and smoking (p<0.0001), black tea drinking (p=0.021), and poor oral hygiene (p<0.0001). Hairy tongue (p<0.0001), coated tongue (p<0.0001), and fissured tongue (p=0.014) conditions were significantly higher in males, while crenation of the tongue was more frequent in women (p<0.0001).ConclusionThis epidemiologic survey of adult dental outpatients of Northern Iran assessing tongue conditions and lesions found the frequency of these conditions in 47.7% of males and 38.6% of females in this population. Tongue conditions and lesions were more frequent among smokers, black tea drinkers, and those with poor oral hygiene. The results of this epidemiological survey can only be interpreted for the population studied and as such cannot be generalized to the wider population of Iran, but future studies should be designed to assess the frequency of these conditions on a countrywide basis.Clinical SignificanceThe results of this study suggest efficient oral hygiene programs and encouraging people to drink less tea and quit smoking may reduce tongue lesions in adult dental outpatients in Northern Iran.CitationMotallebnejad M, Babaee N, Sakhdari S, Tavasoli M.

Dental Management for Patients in ICU
Authors: Rath SK , Kumar U 
Published: July 2019

ABSTRACT
The essence of multi disciplinarity is that professionals from different areas acting on the same patient in intensive care do not rely on the environment or special equipment but on the decision making process, based on the full understanding of the patient's physiological, psychological conditions and of new therapies. It is mandatory that ICU patients receive sufficient oral hygiene care during their stay, for the purpose of preventing oral pathologies and possible complications of already existing oral diseases. There is real need for the effective participation of dentists and the nursing staff in the instructions, professional qualification, and motivation of health professionals working in the ICU in order to create specific routines to promote oral health in ICU patients. Multifaceted interventions to improve oral care nursing practices are required to reduce the incidence of life threatening conditions in mechanically ventilated patients, thereby improving patient safety
