Prevalence of Impacted Maxillary Canines in a Palestinian Population

An impacted tooth means that it is stuck and cannot erupt into function. And the maxillary cuspid, namely maxillary canine, is the second most common tooth to become impacted. Actually, there are four canines: two maxillary canines and two mandibular canines and the canines are critical teeth in the dental arch and play an important role to the dentofacial aesthetics and function.

Considering the importance of canines and due to the impacted maxillary canines is a frequently encountered clinical problem, many studies evaluated the prevalence of impacted canines among various populations and reported vast differences in their findings.

In this paper, a retrospective, descriptive, cross-sectional study of 1321 digital panoramic radiographs was conducted and the authors aimed to estimate the prevalence of impacted maxillary canines in the general population of the city of Nablus, Palestine. The radiographs were obtained from the records of a private dental clinic from the year 2009 till 2016 and were examined by two experienced examiners in order to detect impacted maxillary canines. Then collected data were processed and analyzed by using IBM SPSS Statistics V. 22. Besides, the authors used chi square test to reveal differences in the distribution of impacted canines when stratified by gender, location (left or right), and being unilateral or bilateral.

And the findings showed that the prevalence of impacted canines among the examined population (n = 1321) was found to be 1.8%. There was a significant association between gender and canine impaction (P < 0.05), indicating females had higher prevalence of canine impaction than males. The results also revealed significantly higher unilateral canine impaction compared to bilateral impaction. While, no significant difference in the prevalence of right or left canine impaction was found.

In conclusion, the prevalence of impacted maxillary canines (1.8%) in this study was within the range reported among other populations. And future studies are needed to evaluate the etiology of teeth impaction in Palestine.

Incorporation of High-Altitude Balloon Experiment in High School Science Classrooms

High-altitude balloon is a balloon, filled usually with helium or hydrogen that ascends into an area called “near space” or stratosphere. The most common type of high-altitude balloons are weather balloons. Other purposes include use as a platform for experiments in the upper atmosphere. Modern balloons generally contain electronic equipment such as radio transmitters, cameras, or satellite navigation systems, such as GPS receivers. The mission of the High-Altitude Balloon Experiment (HABE) is to acquire supporting data, validate enabling technologies, and resolve critical acquisition, tracking, and pointing (ATP) and fire control issues in support of future space-based precision pointing experiments. The use of high-altitude balloons offers a relatively low-cost, low-vibration test platform, a recoverable and reusable payload, worldwide launch capability, and a 'near- space' emulation of the future space systems operational scenarios. More recently, several university...

The Influence of Heated Soil in Crop of “Tamaris” Tomato Plants on the Biological Activity of the Rhizosphere Soil

Tomato is a plant with high heat requirements and sensitive to cold weather and frost. The optimum temperature for the growth of tomato plants is between 21˚C and 27˚C during the day and between 17˚C and 21˚C at night. The soil temperature is also very important for plant growth. The optimum soil temperature for tomato cultivation should be within the range 15˚C - 18˚C. Besides, the proper development of the root system depends on the optimal temperature of the soil. A temperature below 14˚C reduces and inhibits the growth of the root system and encourages the development of fungal and bacterial diseases. In this study, the authors aimed to evaluate the effect of heated soil on the population of bacteria, fungi and nematodes inhabiting the soil of tomato cultivar “Tamaris” growing in peat and coconut substrates. The experiment was carried out in 12 treatments and in 3 replications (one slab was one replication). The soils were tested in two different types of containers: cylinders...

Effect of Proline Pretreatment on Grapevine Shoot-Tip Response to a Droplet-Vitrification Protocol

Proline is an α-amino acid that is used in the biosynthesis of proteins. Some studies have shown that proline has been accumulated in plants in response to biotic and abiotic stresses. Exogenous proline has thus been used for improving some plant cryopreservation protocols. Further enhancement of cryopreservation efficiency for  in vitro  grapevines could be expected if stresses linked to cryopreservation procedures could be reduced. In this study, the authors studied the possible beneficial effect of proline in grapevine cryopreservation. Single-node explants from  in vitro  grown grapevine plantlets ( Vitis vinifera  L. cv Portan) were cultured on shooting media (half-strength MS + 1 μM BAP) containing no proline (control) or 50, 500, or 2000 μM filter-sterilized L-proline. Shoot tips excised from these microshoots were subjected to a PVS2-based droplet-vitrification procedure. Control and rewarmed explants were grown on a recovery medium containing ...
