The Role of Saliva in Dental Erosion and a Prosthetic Approach to Treatment: A Case Report
Authors: Bavbek Andac Barkin , Dogan Orhan Murat , Yilmaz Tamer , Dogan Arife 
Published: July 2019

Abstract

Aim
The aim of this report is to describe the relationship of some salivary parameters to dental erosion resulting from excessive citric acid consumption and present a description of a prosthetic approach used to restore the damaged dentition of a patient with severe erosion.

Background
The high consumption of dietary sources of acids can lead to erosion or the excessive wear of dental hard tissues. Erosion may be modified by salivary parameters such as flow rate, pH, and buffering capacity. Porcelain-fused-to-metal (PFM) restorations and composite resin veneers can be used successfully to restore impaired esthetics and eliminate tooth hypersensitivity in such cases.

Results
A 37-year-old woman with a history of excessive lemon consumption presented with a complaint of tooth hypersensitivity and the poor appearance of her dentition due to erosion. Stimulated and unstimulated salivary samples of the patient were evaluated for flow rate, pH, and buffering capacity before and after treatment. The pre-treatment values were found to be higher than post-treatment values. Stimulated samples showed an increase of salivary flow rate, pH, and buffering capacity. The measured parameters put forth the defensive potential of saliva against the acidic diet, and the salivary flow rate and buffering capacity decreased after reducing acidic consumption. The excessively eroded teeth were restored using PFM restorations whereas the superficially eroded teeth were restored with composite resins.

Summary
The introduction of acidic foods, beverages, or other agents can exceed the natural buffering capacity of saliva. The result is a lowering of the pH of the oral environment which can lead to erosion of enamel and dentin. Loss of tooth structure due to erosion can compromise the esthetics of the dentition and lead to hypersensitivity of the teeth. Teeth damaged by erosion can be successfully restored by composite resin or porcelain restorations and esthetics and function of dentition can be improved.

Clinical Significance
This report is a profound example of how the over consumption of acidic agents affect not only dental tissues but also the chemical balance of the oral environment as well as the oral habitat.

Published: July 2019

AbstractAimThe aims of this study were to determine the prevalence of dental caries in three to four-year-old children born pre-term and with a low birth weight (PLBW) to be compared with normal birth-weight children (NBW) and further to investigate the impact of relative risk factors on the development of dental caries in primary teeth.Methods and MaterialsThis cross-sectional case-control study was conducted on 90 children (45 PLBW and 45 NBW). The demographic data and information about feeding practices was ascertained using a structured questionnaire. Dental caries status (dmft) was determined, and the differences between the two groups were tested using the Fisher's exact and the Mann-Whitney U tests at a confidence level of 5%.ResultsTwenty-five children (eight PLBW and 17 NBW) were caries free, and the mean±SD dmft was 2.5±0.3 in PLBW and 2.2±0.4 in NBW children (p>0.05). The length of feeding in PLBW children was lower than the NBW group (p>0.05).ConclusionThe prevalence of dental caries did not differ between the PLBW and NBW children.Clinical SignificanceEnamel hypoplasia and snacking were not common in PLBW children which may account for the lack of difference in dental caries between the two groups.CitationGhasempour M, Ahmadpour-Kacho M, Sheikhi S.

Palatal and Labially Impacted Maxillary Canine-associated Dental Anomalies: A Comparative Study
Authors: Pai Keerthilatha M. , Nagpal Archna 
Published: July 2019

AbstractAimTo determine the association of impacted maxillary canines with other developmental dental anomalies and compare them with a control population and to compare palatally and labially impacted canine associated anomalies.Methods and MaterialsNinety non-syndromic orthodontic patients from a south Indian population, with either labial or palatal impactions of one or both maxillary canine teeth, were selected for the study group. A group of 250 patients who had normally erupted maxillary canines were selected as controls. Clinical findings and panoramic radiographs were used to identify dental anomalies.ResultsPrevalence of premolar rotation was found to be 80% in the study group followed by canine rotation (20%), taurodontism (26.6%), infraocclusion of premolars (25.5%), impacted mandibular canine (11.1%), and peg lateral (7.7%). Forty-nine (54.4%) palatally impacted, 37 (41.1%) labially impacted, and 4 (4.4%) centrally impacted canines were also observed. Of the 250 subjects in the control group 78.8% presented with premolar rotation. Maxillary canine transmigration, infraocclusion of premolars, anomalies of maxillary lateral incisors, and taurodontism showed significant associations with palatally impacted canines (P<0.05).ConclusionThe present study illustrates a significant association of anomalous maxillary lateral, anomalous mandibular canine, taurodontism, infra occlusion of premolar, over retained deciduous molar, and maxillary canine transmigration with ectopically placed canines. These associations suggest these conditions may share a common genetic origin and existence of these anomalies can anticipate maxillary canine impaction which can help in cautious observation and early treatment for maxillary canine impaction.Clinical SignificanceAnomalous lateral incisors can serve as a predictor for palatal maxillary canine impaction. These anomalies could serve as an easily recognized, early warning sign for the monitoring of the canine position and timely early referral in appropriate cases.CitationNagpal A, Pai KM, Sharma G.

Dental Treatment Duration as an Indicator of the Behavior of 3- to 9- Year-old Pediatric Patients in Clinical Dental Settings
Authors: Aminabadi Naser Asl , Oskouei Sina Ghertasi , Farahani Ramin Mostofi Zadeh 
Published: July 2019

Abstract

Aim
The aim of this study was to evaluate the age-specific effect of treatment duration on pediatric patient behavior.

Methods and Materials
A total of 450 children 3 to 9 years of age were allocated into six consecutive age groups (n=75 for each group). All children received dental treatment procedures which included the fabrication of a Type 1 composite resin restoration, then a dental prophylaxis followed by fluoride therapy with each procedure requiring an average of 20 minutes. The children's behavior was evaluated at the end of each treatment period using the sound, eye, and motor (SEM) scale.

Results
The results of a mixed analysis of variance (ANOVA) indicated a significant main effect of treatment duration, F (1.69, 255.01) = 188.29, P < 0.001, and of chronological age, F (1, 144) = 115.82, P < 0.001. Moreover, the main effects of time and chronological age was qualified by a significant interaction between time and chronological age, F (8.86, 255.01) = 115.82, P < 0.001. The beta weights (0.64 for age versus 0.44 for time) suggest chronological age contributes the most to predicting the behavior of children during dental treatment followed by the duration of treatment.

Conclusion
Treatment duration may affect the behavior of pediatric patients parallel with chronological age and, thus, should be considered in the arrangement of the treatment plan.

Clinical Significance
The findings of this study suggest appropriate pediatric behavior management should include thoughtful scheduling of appointments according to a treatment plan formulated with consideration of the effects of age and appointment length.

The Effect of Various Placement Techniques on the Microhardness of Class II (Slot) Resin Composite Restorations
Authors: Moosavi Horieh , Abedini Somayye 
Published: July 2019

Abstract

Aim
To analyze the influence of various placement techniques on Vickers microhardness of Class II cavities restored using resin composite in different depths and layers.

Methods and Materials
Sixty-four standardized Class II cavities (5.0 × 3.0 × 1.5 mm3) were prepared in sound human, maxillary premolars. The cavities were divided into four experimental groups (n=16) according to the composite placement technique used: incremental technique using a Palodent matrix (IP), incremental technique using a transparent matrix (IT), centripetal technique using a Palodent matrix (CP), and the centripetal technique using a transparent matrix (CT). The cavities were restored with Single Bond, Z100 composite resin system. After 24 hours of storage in envelopes in an amber-colored box, the restorations were finished, polished, and kept for one week before conducting a hardness test. The microhardness test was carried out using a 0.5 kg load for 20 seconds at different depths and layers of proximal surfaces. Statistical analysis was done using a t-test, ANOVA, and a Tukey's test (α=0.05)

Results
In contrast, the matrix bands, the methods of composite insertion, had a significant effect on hardness. The greatest surface hardness of resin composite was related to the use of the centripetal technique and a transparent matrix (p<0.05). With regard to cavity depths, the hardness at the top surface was significantly greater, followed by the middle and bottom cavity depths. A greater hardness was obtained in the mesial-distal direction within the external layer compared with the middle and internal layers using the centripetal method (p<0.05).

Conclusion
The kind of matrix and filling technique could have a significant effect on surface microhardness. The top surface had the greatest hardness in comparison to different depths. In the centripetal technique, the external layer of the proximal wall had greater hardness than the other layers.

Clinical Significance
While the microhardness of all of the experimental placement techniques in the different depths and layers was within a clinically acceptable range, the greatest hardness was obtained using the centripetal technique with a transparent matrix, making it the technique of choice.

Effect of Postoperative Bleaching on Marginal Leakage of Resin Composite and Resin-Modified Glass Ionomer Restorations at Different Delayed Periods of Exposure to Carbamide Peroxide
Authors: Moosavi Horieh , Ghavamnasiri Marjaneh , Manari Vahideh 
Published: July 2019

AbstractAimTo evaluate the effect of dental bleaching with carbamide peroxide at different exposure times on the microleakage of resin composite and resin-modified glass ionomer restorations after placement in extracted human teeth.Methods and Materials120 Class V cavity preparations were placed at the cementoenamel junction (CEJ) of human teeth. Half of the cavities were restored with Filtek P60 resin composite(C) and the other half were restored with Fuji II LC resin-modified glass ionomer (G). Each group was randomly divided into four subgroups (n=15). Groups C1 and G1 were not bleached and stored in artificial saliva at 37°C to serve as control groups, while in Groups C2 and G2, C3 and G3, and C4 and G4 specimens were exposed to a 15% carbamide peroxide gel for one day, one week, and two weeks, respectively, following the placement of restorations. Microleakage was assessed using the dye penetration method. Data were analyzed using the Kruskal-Wallis and Wilcoxon tests (p=0.05).ResultsThe Kruskal-Wallis test showed no significant difference among all groups of composite or glass ionomer restorations with either enamel or dentinal margins with regard to microleakage (p>0.05). The Wilcoxon test revealed more marginal leakage in the enamel/ glass ionomer margins than the enamel/ composite margins (p<0.05). In comparisons within each group, the Wilcoxon test showed there was more microleakage in dentinal margins of composite restorations than in the enamel margins in the test groups (p<0.05). The dentinal margins of the glass ionomer in control groups showed more leakage than the enamel margins, but after the bleaching procedure all experimental groups showed statistically similar microleakage in both the enamel and dentinal margins (p>0.05).ConclusionsPostoperative bleaching with carbamide peroxide could increase microleakage in the dentinal margins of composite and the enamel margins of resin-modified glass ionomer restorations.Clinical SignificanceRebonding of resin composite restorations should be considered following bleaching with 15% carbamide peroxide in order to reseal the margins. Resin-modified glass ionomer is not suitable as a filling material before bleaching because of its susceptibility to increased microleakage.CitationMoosavi H, Ghavamnasiri M, Manari V.

Adhesive Bond Strengths Using Self- and Light-Cured Composites
Authors: Walter Ricardo , Macedo Georgia V. , Oliveira Gustavo M. S. , Swift Edward J. 
Published: July 2019

Abstract

Aim
To evaluate the microtensile bond strength (μTBS) of four adhesive systems to dentin, using self- and light-cured resin composites.

Methods and Materials
Crowns of human molars were separated from the roots, and the occlusal surfaces were ground to obtain flat superficial dentin. Three etch-and-rinse adhesives—All-Bond 2, One-Step Plus, and OptiBond Solo Plus—and one self-etching primer system, Peak SE, were evaluated. Each adhesive group was divided into two subgroups according to the type of resin composite used. A self-cured (Bisfil 2B) or light-cured (Filtek Supreme Plus) resin composite build-up was incrementally inserted to the dentin after each adhesive system was applied. The bonded specimens were stored in water for 24 h and sectioned into beams. Microtensile testing was done, and the data were subjected to ANOVA and Fisher's PLSD test.

Results
The μTBS of All-Bond 2 and One- Step Plus was not affected by the type of resin composite used (p=0.3131 and p=0.1562, respectively). The μTBS of OptiBond Solo Plus was significantly reduced when used with selfcured resin composite (p<0.0001). Peak SE formed no bond of self-cured resin composite to dentin.

Conclusions
Some adhesives do not effectively bond self-cured resin composite to dentin.

Clinical Significance
Incompatibility between adhesives with low pH and certain self-cured resin composites can cause clinical debonding of restorations.

Relationship Between Patients’ Oral Health–Related Quality of Life, Satisfaction with Dentition, and Personality Profiles
Authors: AL-Omiri Mahmoud K , Al Quran Firas A. M. , Al-Hamad Khaled Q. , Karasneh Jumana 
Published: July 2019

Abstract

Aim
The aim of this study was to investigate the relationship between patients’ oral health–related quality of life, satisfaction with their dentition, and their personality profiles.

Methods and Materials
Eighty-four patients (30 males and 54 females; mean age 31.9±12.7 years) seeking routine dental treatment were recruited for this study. A “Dental Impact on Daily Living” (DIDL) questionnaire was used to assess dental satisfaction and impact on daily living. An “Oral Health Impact Profile” (OHIP) was used to measure self-reported discomfort, disability, and dysfunction caused by oral conditions. Oral health–related quality of life was assessed using the “United Kingdom Oral Health Related Quality of Life” measure (OHQoL-U.K). A “NEO Five Factor inventory” (NEO-FFI) was used to assess personality profiles.

Results
The dentition has a measurable impact on daily living as well as with satisfaction with appearance, pain levels, oral comfort, general performance, and eating capability (p=0.000). Younger patients had more profound oral health impacts (p=0.045) and higher neuroticism scores (0.043). OHIP scores were significantly related to OHQoL-UK scores (p=0.000). DIDL scores had significant correlations with OHIP and OHQoLUK scores (p<0.05). Significant correlations were established between neuroticism and satisfaction with oral comfort, extraversion and total satisfaction and satisfaction with general performance, and openness and satisfaction with appearance (p<0.05). OHIP and OHQoLUK scores had no significant correlations with psychological profiles.

Conclusions
The status of the oral cavity can have a definitive impact on patients’ daily living and quality of life regardless age, gender, and level of education. Patients’ satisfaction with their dentition has definitive impacts on daily living, quality of life, and dental perceptions. Personality profiles (neuroticism; extraversion, and openness) may influence dental perceptions, play a significant role in shaping satisfaction with dentition, and help with the prediction of the dental impact on daily living.

Clinical Significance
Since patients’ satisfaction with their dentitions impacts their daily living and quality of life while affected by their psychological profiles, this should be considered when formulating a treatment plan for management for their dentition in order to obtain patient acceptance of the proposed treatment.

A New Concept in Restorative Dentistry: Light-Induced Fluorescence Evaluator for Diagnosis and Treatment: Part 1 – Diagnosis and Treatment of Initial Occlusal Caries
Authors: Tassery Hervé , Koubi Stephen , Terrer Elodie , Dionne Alexandro , Weisrock Gauthier , Sarraquigne Caroline , Mazuir Alain 
Published: July 2019

Abstract

Aim
The objective of this in vivo experiment is to propose an innovative therapeutic concept using a light-induced fluorescence evaluator for diagnosis and treatment (LIFEDT) that is based on the imaging and autofluorescence of dental tissues.

Background
Processes with the aim of diagnosing carious lesions in the initial stage with optimum sensitivity and specificity employ a wide variety of technologies, but like the conventional diagnosis tools, they remain either inefficient or too subjective.

Technique
This experiment evaluated a fluorescence light-induced camera that illuminates tooth surfaces within an excitation radiation band of light with a wavelength of 450 nm and facilitates a high magnification image.

Conclusions
An analysis of 50 occlusal grooves revealed three clinical forms of enamel caries: (1) enamel caries on the surface, (2) suspicious grooves with a positive autofluorescent red signal, and (3) suspicious grooves with a neutral fluorescent dark signal. Two decision-making diagrams were proposed in accordance with international recommendations for preventive dentistry, but modified as a result of the accurate information obtained with this new LIFEDT device.

Clinical Significance
The lighting of suspect occlusal grooves with the SoproLife® camera enables observation of any variations in the optical properties to refine a caries diagnosis and facilitates more than a 50x magnification of occlusal groove anatomy to provide additional information on the carious potential of the tooth surface.
