ABSTRACT

Introduction
Dental caries and obesity are two of the most prevalent health conditions affecting children. Relative decrease in corporeal movements, escalating inactive lifestyles, and changes in dietary factors are strongly linked with the increasing incidence of overweight and obesity. Furthermore, obesity increases the risk of chronic disease and dental caries that significantly affects the quality of life of young children. The present study intends to explore the relationship between dental caries and obesity in children in Al-Kharj city, Kingdom of Saudi Arabia.

Materials and methods
The present descriptive study was designed as a cross-sectional study in which a total of 386 children in the age range of 6 to 12 years from elementary schools of Al-Kharj city and pediatric dental clinics in Prince Sattam Dental College were included.

Results
Mean decayed filled teeth (DFT) score was found to be considerably higher among obese children. Also, incidence of dental caries in deciduous dentition was found to be notably higher among obese children.

Conclusion
Obesity has a considerable outcome on prevalence of dental caries among primary schoolchildren in Al-Kharj city, Kingdom of Saudi Arabia. The importance of obesity is limited not only to systemic disorders but also in relation to carious lesions. Hence, educating primary schoolchildren about caries and its related factors is very important.

Clinical significance
High intake of free sugar is a wellestablished risk factor for dental caries and also for obesity. Therefore, it is speculated that factors that decrease these risk factors have the potential to affect both conditions at the population level to control it competently.

ABSTRACT

Introduction
One of the possible mechanisms for the gradual destruction of bond strength in dentin-resin interface, could be due to the demineralized unstable collagen matrix. Use of protease inhibitors, such as tannic acid (TA) could prevent destruction of collagen fibers. The aim of this study was to compare the TA effect on bond strength of etch and rinse and self-etch adhesive systems in the dentin of primary teeth.

Materials and methods
This in vitro study was done on 40 extracted primary molar teeth. The teeth were sectioned in the mesiodistal direction, and enamel of buccal and lingual surfaces was removed. Samples were randomly divided into four groups: Single bond (SB) + TA, SB, Clearfil SE Bond (CSB) + TA, and CSB. Then, Z250 and Clearfil AP-X composites were cured on the surfaces of SB and CSB groups respectively. After that, all samples were divided into aging and non-aging groups. For 3 months, samples were placed under 1,000 thermal cycles in aging group. Subsequently, the shear bond strengths of all groups were measured by the International testing machine, and failure mode was evaluated by an optical stereomicroscope. Data were analyzed with paired t-test and independent t-test.

Results
Tannic acid induced a significant reduction in the immediate bond strength of adhesive SB. Meanwhile, TA had no significant effect on shear bond strength of the CSB system.

Conclusion
Based on our findings, use of TA is not recommended with SB and CSB adhesives on primary teeth.

Clinical significance
Tannic acid may not be considered in resin restorations of primary teeth.

ABSTRACT

Introduction
Malocclusions with anterior crossbite are a major esthetic and functional concern for patients. This case report presents a 27-year-old Syrian female who was diagnosed with a class 3 malocclusion, combined with anterior crossbite, deep bite, concave profile, and inadequate maxillary incisor exposure. There was a centric occlusion (CO)/centric relation (CR) discrepancy and the mandible could be manipulated to near edge-to-edge incisal relation.
Correction was done by class 3 intermaxillary elastics on upper and lower mini-implants for the first 6 months, followed by preadjusted edgewise appliance. The objective of implantsupported elastics was to adapt the patient for the CR condylar position without dental effect. Treatment was completed in 24 months with satisfactory dental and facial relationship.

ABSTRACTContextOral conditions and their impacts on quality of life (QoL) are now important as a tool to evaluate patients’ perception of treatment offered to them. There are various indexes used as a tool to assess the QoL of the individual. The general oral health assessment index (GOHAI) is a proven and reliable index to assess the oral health and its impact on oral healthrelated quality of life (OHRQoL).AimTo evaluate the effect of complete denture rehabilitation on OHRQoL in completely edentulous patients.Settings and designThe study compares the improvement of OHRQoL of 50 completely edentulous patients enrolled in the study, after rehabilitation of them with conventional complete dentures.Materials and MethodsHindi version of the GOHAI was used as evaluation tool for OHRQoL.Statistical analysisWilcoxon signed-rank test was applied to assess changes in GOHAI score before and after rehabilitation with a complete denture.ResultsThe GOHAI score was seen to be increased from 22.30 ± 1.67 to 27.48 ± 1.13 (p-value < 0.000), which was highly significant.ConclusionThe GOHAI is an example of a patient-based assessment of oral health problems commonly affecting older adults. The GOHAI assessment indicates improvement in chewing. The highest change between pre- and postinsertion scores was 92.75% for biting or chewing any kind of food.How to cite this articlePatel J, Sethuraman R, Prajapati P, Patel J.

Comparison of Pain Perception for Nasopalatine Nerve Block using Conventional and Computerized Local Anesthesia Delivery Systems in Adults: A Randomized Split-mouth Clinical Study
Authors: Kohale Bhagyashree R , Agrawal Amit A , Erlewad Dinesh 
Published: December 2016

ABSTRACTIntroductionProfound local anesthesia (LA) is necessary in order to reduce patient discomfort during oral surgical procedures. However, injection technique itself may be a potentially painful procedure. A comfortable and consistent LA can increase the level of trust between the patient and the operator, since even a thought of intraoral injection causes a considerable amount of anxiety in many patients. To reduce this anxiety, a computer-controlled local anesthesia delivery (CCLAD) system is commercially available as a possible means of minimizing the sensation of pain (especially for palatal injections).AimThe aim of the present study was to compare the pain perception, when injections were administered using the CCLAD system or a conventional technique in patients requiring oral surgical procedures in the maxillary anterior region.Materials and MethodsThis randomized split-mouth study included 15 patients (7 females and 8 males). Conventional syringe or computerized single tooth anesthesia (STA) system with a 30-gauge needle was used to give nasopalatine nerve block by the same operator, over a minimum gap of 7 days. Immediately after injection, patient's pain perception was assessed using numeric rating scale (NRS). Overall difference in pain perception and effect of change in sequence of type of anesthesia were determined using unpaired t-test.ResultsResults of the study showed statistically significant difference between the pain scores of STA system and conventional injection technique; however, the change in sequence of anesthesia technique did not show any effect on the effectiveness of STA system.ConclusionThe STA system significantly reduces the pain perception after administration of nasopalatine nerve block in adults.Clinical significanceUse of STA system for administration of nasopalatine nerve block in adults provides better patient acceptance and pain control over conventional cartridge syringe.How to cite this articleKohale BR, Agrawal AA, Erlewad D.

ABSTRACTThe purpose of this study was to describe and measure the size of sella turcica in subjects with different skeletal types. Lateral cephalometric radiographs of 120 individuals (60 males and 60 females) with an age range of 11 to 26 years were taken and distributed according to skeletal classification: 40 class I (ANB: 20–40), 40 class II (ANB: >40), and 40 class III (ANB: <20). The sella turcica on each radiograph was analyzed and measured to determine the linear dimensions of length, depth, and diameter. Student's t-test was used to calculate differences in linear dimensions, while a one-way analysis of variance was performed to study the relationship between skeletal type and sella size. No significant differences in linear dimensions between genders could be found. When age was evaluated, significant differences were found between the older (15 years or more) and the younger (11–14 years) age groups at the 0.01 and 0.001 levels for length, depth, and diameter. Sella size of the older age group was larger than in the younger age group. When skeletal type was compared with sella size, a significant difference was found in the diameter of sella between the classes II and III subjects (p < 0.01). Larger diameter values were present in the skeletal class III subjects, while smaller diameter sizes were apparent in class II subjects (multiple comparison tests). When gender, age, and skeletal type were all compared with the size of the sella (regression analyses), age was significantly related to a change of length (p < 0.01) and diameter (p < 0.001).How to cite this articleZanke PN, Patni V, Sonawane M, Karandikar G, Ravindranath VK, Maskarenj M.

Management of a Flared Root Canal with an Iatrogenically Widened Apex
Authors: Bolli Rashmi V , Agrawal Aanchal M 
Published: December 2016

ABSTRACT
Overinstrumentation during root canal treatment is one of the causes for iatrogenic enlargement of the root apex. It also leads to unwarranted coronal third widening, which results in thinning of the dentinal walls and makes the tooth susceptible to fracture. Another difficulty arises during control of obturation material within the canal. Such cases can be managed with obturation using mineral trioxide aggregate (MTA) followed by of root reinforcement for the weakened dentinal walls. In the present case, a 5mm MTA plug was placed and root reinforcement was done with the help of Giomer. Postendodontic restoration was done with a cast post and a full coverage porcelain fused to a metal crown was cemented in place.

ABSTRACTResidual ridge deformity after tooth loss is an expected outcome. The treatment of a patient with a history of trauma with loss of teeth and ridge defect is a significant challenge. This article presents a case of Seibert's class III ridge defect in the maxillary anterior region, which was treated with a fixed-removable system, the Andrew's bridge, for economical and time constraints. It requires a castable bar and sleeve attachment, which provides precision and retention while seating. It is primarily indicated where abutments are capable of supporting a fixed partial denture, but residual ridge shows severe loss.How to cite this articleRam SM, Nigam AA, Nadgere JB, Shah NP.

2016/53 Landmark decision by Austrian Supreme Court: Face veil ban for employees is lawful (AT)
The Austrian Supreme Court has ruled that the general prohibition of Muslim face veils by an employer does not constitute unlawful discrimination. In this landmark decision, Austria’s Supreme Court expresses the view that an uncovered face is a prerequisite to proper communication. Thus, termination of employment by reason of an employee’s refusal to come to work unless she can wear a face veil is not unlawful under the Austrian Equal Treatment Act. Whether this rule also applies to other religious clothing such as headscarves remains to be seen.

2016/55 New Supreme Court decision on the distinction between independent contractors and employees (NO)
EU employment protection is usually limited to “employees”, meaning that independent contractors are not covered. However, EU law often leaves it to Member States to determine the meaning of employee. The directives regulating transfers of undertakings, collective redundancies, written working conditions, information and consultation, part-time work, temporary agency workers etc. are all examples of protection covering only ‘employees’ as defined by each Member State.Consequently, the interpretation of ‘employee’ at the national level determines whether protection in EU law applies. This case report concerns the distinction between an independent contractor and employee. The question was whether a support worker for a child needing extra care and support should be considered as employed by Ålesund municipality. The majority (4-1) found that the support worker was an employee. The case illustrates how the notion of employee in Norwegian law adapts to new ways of organising work and may be of interest in other jurisdictions.

2016/61 The court awards for victimisation resulting from sexual harassment, even though the claim for sexual harassment itself was time-barred (CY)
The Industrial Disputes Court considered certain substantive and procedural issues in the context of a claim for sexual harassment and victimisation. This case provides a good illustration of the principles the tribunals apply when examining sexual harassment cases and how these are interpreted by Cypriot employment courts.

AbstractThe Niger Delta is one of the largest hydrocarbon basin offshore Africa and it is well known for the presence of active pockmarks on the seabed. During the Guineco‐MeBo cruise in 2011, long cores were taken from a pockmark cluster in order to investigate the state of its current activity. Gas hydrates, oil, and pore‐water were sampled for geochemical studies. The resulting dataset combined with seismic data reveal that shallow hydrocarbon migration in the upper sedimentary section was focused exclusively within the pockmarks. There is a clear tendency for gas migration within the hydrate‐bearing pockmarks, and oil migration within the carbonate‐rich one. This trend is interpreted as a consequence of hydrate dissolution followed by carbonate precipitation in the course of the evolution of these pockmarks. We also demonstrate that Anaerobic Oxidation of Methane (AOM) is the main process responsible for the depletion of pore‐water sulfate, with depths of the Sulfate‐Methane Transition Zone (SMTZ) ranging between 1.8 and 33.4 m. In addition, a numerical transport‐reaction model was used to estimate the age of hydrate‐layer formation from the present‐day sulfate profiles. The results show that the sampled hydrate‐layers were formed between 21 and 3750 years before present. Overall, this work shows the importance of fluid flow on the dynamics of pockmarks, and the investigated cluster offers new opportunities for future cross‐site comparison studies. Our results imply that sudden discharges of gas can create hydrate layers within the upper sedimentary column which can affect the seafloor morphology over few decades.

Published: December 2016

AbstractDawsonite is often associated with CO2‐rich gas reservoirs, and it is regarded as a “trace mineral” for recording migration and accumulation of CO2. Following accepted petrological, mineralogical, and geochemical principles, we used several methods (described herein) to study the Cretaceous dawsonite‐bearing sandstone reservoirs in the Songliao Basin, China. We used the ideas of “sequencing” and “timing” to verify the influx stages of CO2 and hydrocarbons, dividing their influx sequence pattern and building a CO2‐influx timeframe. First, we determined the stable isotopic ratios of dawsonite and CO2 in gas and oil reservoirs, and found that the CO2 in? dawsonite is of a mantle‐derived magma origin. Second, we differentiated an early/late‐stage oil and gas influx and a midmantle source influx through the study of diagenetic paragenetic sequences, formation water, and fluid inclusions in the dawsonite‐bearing sandstones. Combining burial/thermal‐history curves and illite K‐Ar dates from the study area, we determined that the early‐stage oil and gas influx, late oil and gas influx, and medium CO2 influx occurred at 85–58.8 Ma, 41–20 Ma, and 58.8–41 Ma (Paleocene and Eocene), respectively. Finally, we observed a coupling relationship between CO2 influx and Shuangliao volcanic activities and material compositions, as constrained by volcanic activity history in the basin since the Late Cretaceous.
Trade winds drive pronounced seasonality in carbonate chemistry in a tropical Western Pacific island cave—Implications for speleothem paleoclimatology

AbstractCarbon dioxide concentrations in caves are a primary driver of rates of carbonate dissolution and precipitation, exerting strong control on speleothem growth rate and geochemistry. Long‐term cave monitoring studies in midlatitude caves have observed seasonal variability in cavepCO2,whereby airflow is driven by temperature contrasts between the surface and subsurface. In tropical settings, where diurnal temperature cycles are larger than seasonal temperature cycles, it has been proposed that caves will ventilate on daily time scales, preventing cavepCO2from increasing substantially above atmosphericpCO2. By contrast, the relatively small temperature difference between the surface and subsurface may be insufficient to drive complete ventilation of tropical caves. Here we present results of an 8 year cave monitoring study, including observations of cavepCO2and carbonate chemistry, at Jinapsan Cave, Guam (13.4°N, 144.5°E). We find that cavepCO2in Jinapsan Cave is both relatively high and strongly seasonal, with cavepCO2ranging from 500 to 5000 ppm. The seasonality of cavepCO2cannot be explained by temperature contrasts, instead we find evidence that seasonal trade winds drive cave ventilation and modulate cavepCO2. Calcite deposition rates at seven drip sites in Jinapsan Cave are shown to be seasonally variable, demonstrating that speleothem growth rates in Jinapsan Cave are strongly affected by seasonal variations in cavepCO2. These results highlight the importance that advection can have on cave ventilation processes and carbonate chemistry. Seasonality in carbonate chemistry and calcite deposition in this cave affect the interpretation of speleothem‐based paleoclimate records.
