Dental abnormalities of a long-term survivor of a childhood hematological malignancy
Authors: Raja Zarina R.S , Nik-Hussein N.N. 
Published: April 2015

The treatment of haematological malignancy is multimodal and involves chemotherapy, radiotherapy and/or bone marrow transplants. With the advancement in cancer therapy, there is an increase in the survival of many children with childhood haematological malignancy. In addition, the late effect of the oncology treatment to the orofacial and dental development becomes significant in terms of the potential clinical impact that may affect the quality of life of the survivor. The severity of the long-term effects is dependent on the age of the child at initiation of treatment and whether chemotherapy is combined with radiation or not. The dental treatment may become more complex if the patient requires advanced restorative dental care and the roots malformation may complicate orthodontic treatment. Therefore these patients may require a scheduled careful preventive programme, long-term follow up, with prophylactic treatment and intervention at appropriate time to minimize the consequences of the disease and the given therapy.

Evaluation of fissure sealant applied to topical fluoride treated teeth
Authors: El-Housseiny Azza , Sharaf Aly 
Published: April 2015

Fissure sealant is an important tool in the prevention of dental caries. This study evaluated the effect of treating the enamel with topical fluoride gel prior to acid etching on sealant retention clinically (Part I) and in vitro (Part II). In part I a split mouth design using contralateral first permanent molars was conducted. Seventy (35 pairs) molars were sealed. Fissure sealant was applied on one side of the mouth (control group) and the contralateral tooth received acidulated phosphate fluoride gel (test group) prior to acid etching. The sealant was evaluated after 6 and 12 months and scored as intact, partially lost or completely missing.In part II, the shear bond strength between sealant and buccal enamel of extracted permanent molars without or with topical fluoride treatment was evaluated. Results showed no statistically significant differences between the test and control groups either clinically or in vitro. It is concluded that topical fluoride application prior to acid etching does not have a deleterious effect on sealant retention. However, further investigations should be conducted using different types of fluoride before altering the traditional practices.
An in vitro evaluation of microleakage in class I preparations using 5th, 6th and 7th generation composite bonding agents
Authors: Kallenos Theodosis , Al-Badawi Emad , White G. 
Published: April 2015

The intent of this study was to evaluate microleakage of newer generations of dentinal bonding systems of Class I restorations filled with the same resin based composites. Eighty extracted human premolar and molar teeth were randomly assigned to four groups for bonding: the 5th generation bonding system (Optibond Solo), the 6th generation bonding system (Prompt-L-Pop) and the 7th generation bonding system (iBond), and a control group that was used with no dentinal bonding system. Cavities were prepared 3mm in width, 2mm in depth and 2mm in length. Margins of the cavities were chamfered using a high-speed hand piece with water spray and a #1/2 round diamond bur. The cavities were restored with resin based composites after the application of the dentinal bonding systems according to the instructions of the manufacturer. Upon drying of the teeth, two coats of nail varnish were applied covering the surface of the tooth, excluding the tooth-restoration interface. Samples were thermocycled and immersed in methylene blue dye (0.05%). Each sample was sectioned with an Isomet and evaluated, for microleakage using light microscopy under a measuring microscope at 50x magnification
Statitical significance was determined using the Chi-Square Test. Among the three dentinal adhesive systems used in this study the 5th generation outperformed both the 6th and 7th generation bonding systems.

Authors: Todd Grooms Michael , Ann Keels Martha , Roberts Michael , McIver F. Thomas 
Published: April 2015

The purpose of this cross-sectional study was to examine whether children with attention-deficit / hyperactivity disorder (ADHD) had a total caries experience that was equivalent to children without the disorder.
Methods: The test sample included children ages 6 to 10 years old diagnosed with ADHD by physicians at Duke University Medical Center. The control group also included healthy children 6 to 10 years old without the diagnosis of ADHD.A visual dental exam for caries was performed and a sample of whole, unstimulated saliva was collected. The parent / guardian of each participant completed a health/medication history and a questionnaire concerning the child's oral health and habits, daily routine, and demographic information.
Results: Wilcoxon and chi-square tests showed that children with ADHD have significantly more enamel caries in the primary and permanent dentitions and a significantly higher prevalence of total caries experience when compared to controls. There was no significant difference in whole saliva production between the ADHD children and the controls.
Conclusions: Dentists should be aware that children with ADHD are at higher risk for caries.
Focal dermal hypoplasia: oral and dental findings
Authors: Tejani Zahra , Batra Puneet , Mason Carol , Atherton David 
Published: April 2015

Focal Dermal Hypoplasia/Goltz Gorlin syndrome is a rare syndrome characterized by widespread dysplasia affecting tissues of mesodermal and ectodermal origin with cutaneous, osseous, ocular, oral and dental defects. Enamel hypoplasia is the most commonly reported dental manifestation and has recently been described as a possible manifestation of Lyonisation. This article reviews the reported dental findings and reports a new case with typical findings of focal dermal hypoplasia, which has been under review on our department for 10 years. It discusses the differential diagnosis as well as newer concepts of aetiology and pathogenesis in relation to dental anomalies.Enamel hypoplasia may make plaque control difficult, resulting in generalized gingivitis. Hand anomalies may limit dexterity and exacerbate this. From the dental standpoint we emphasize the implementation of timely preventive and/or therapeutic strategies. Since there are periods of exacerbation during the course of this syndrome, regular surveillance from an early age with the frequency of visits increasing during and after adolescence is indicated. The role of the dentist in improving aesthetics and function can have tremendous psychological impact to enhance self-esteem of such patients.
Early childhood caries (ECC): a preventive-conservative treatment mode during a 12-month period.
Authors: Peretz Benjamin , Gluck George 
Published: April 2015

Purpose: to evaluate a preventive treatment mode for early childhood caries (ECC).
Population and methods: The population to be studied included 30 children who, over a 12-month period, presented with ECC to a private dental clinic. Parents preferred non-invasive, preventive treatment over restorations. Parents were given hygiene and proper feeding instructions. Mesial slicing was performed where proximal caries was observed. Children were examined once every two months. They received supervised professional topical fluoride treatment. Plaque level, brushing, stopping the bottle, eating sweets, appearance of new lesions or exacerbation of existing condition were observed and recorded.
Results: in the vast majority of patients, the progression of ECC was arrested after the preventive regimen. Three children required restorations. They had failed to limit sugar consumption and to comply with brushing instruction. General improvement was observed in plaque control, brushing habits and sweets consumption.
Conclusion: preventive measures may successfully arrest ECC and thereby avoid invasive procedures as well as the need of anesthesia.
Relationship between tooth irregularity and periodontal disease in children with regular dental visits
Authors: Abu Alhaija Elham , Al-Wahadni Ahed 
Published: April 2015

Objectives: The aim of this study was to investigate any association between irregular teeth and periodontal breakdown among children who attend dental clinics regularly.
Methods: The subjects were 80 children (39 females and 41 males) with a mean age of 12.38 ± 0.75 years. Each subject had an alginate impression in the mandibular arch, periapical radiographs for the lower incisor teeth and clinical examination for periodontal health. Plaque accumulation, gingival condition and probing depth, bone level and status of lower incisor teeth contact areas were recorded. Spearman correlation test was used to observe any relationship between the clinical variables.
Results: The average probing depth, gingival index and plaque index scores in the subjects studied were 1.3±0.25, 0.99±0.28 and 1.17±0.52 respectively. The average number of sites with labiolingual displacement with mesiodistal overlap was 1.81±1.30 and those without mesiodistal overlap was 1.39±1.10. The average number of contact areas with spacing was 0.59±1.23. The correlation observed between irregularity and periodontal health indicated no association between the number and type of displacement and plaque accumulation, gingivitis, attachment loss and alveolar bone level.
Conclusion: There was no association between irregularity of teeth and periodontal diseases in presence of good oral hygiene.

Authors: Makris N , Tsiklakis K , Alexiou K , Vierrou A , Stefaniotis Th 
Published: April 2015

Objectives: To compare the diagnostic quality of orthopantomographs made with the conventional unit Orthophos Siemens and the direct digital unit Planmeca 2000 cc Proline among children 6-10 years old and to investigate possible differences on image interpretation between oral radiologists and pediatric dentists.Methods: Study material included two independent groups of panoramic images (50 in each group) made with different panoramic modalities (digital, conventional). Eight observers (four pediatric dentists and four oral radiologists) evaluated all images for diagnostic quality in 12 pre-determined areas using a 4-point rating scale.Results: Digital and conventional panoramic radiography performed almost similarly as far as it concerns the specific diagnostic tasks rated with the exception of the interproximal contacts of mandibular molars where digital panoramic radiography was scored significantly higher and the periapical region of anterior mandible and anterior mandibular tooth germs where conventional panoramic radiography was found to be significantly better. Both oral radiologists and pediatric dentists graded similarly digital and conventional radiographs for a variety of diagnostic tasks.Conclusions: It can be concluded that diagnostic image quality obtained with the digital orthopantomograph unit Planmeca 2000 cc Proline was generally equal to image quality obtained with the conventional orthopantomograph unit Orthophos Plus CD. Image interpretation between oral radiologists and pediatric dentists was not substantially different

Authors: Abu Alhaija Elham 
Published: April 2015

Objective: This longitudinal retrospective cephalometric study was undertaken in an attempt to evaluate the effect of upper removable appliances on the hard and soft tissue structures in subjects with postural Class III.Methods: The material consisted of cephalometric films of 17 Class III patients (8 females and 9 males, with a mean age of 10.10 ± 1.63). Each treated patient was matched before treatment with Class III subject for sex and age. Differences in treated group at T1 and T2 and between treated and untreated groups were examined using paired t-test and independent t-test respectively.Results: Treated and untreated Class III subjects differed in mandibular prognathism (SNB, P&lt;0.01). Upper incisors proclined and inter-incisal angle reduced during treatment (P&lt;0.001). Soft tissue A point moved anteriorly as maxillary incisors were proclined (P&lt;0.05). Soft tissue profile was improved (NNP, P&lt;0.05; NAP, P&lt;0.01).Conclusion: Skeletal, dental and soft tissue changes were found in patients treated by upper removable appliance in postural Class III patients.Clinical relevance: upper removable appliance is an efficient method to procline upper incisors in postural Class III malocclusion and may be of greater influence in improving soft tissue profile.

Published: April 2015

Talon cusp is a rare dental anomaly often associated with systemic conditions such as Rubenstein-Taybi Syndrome,Ellis-van Crevald Syndrome and Incontentia pigmenti achromians. It has not been previously reported as occurring in Alagille Syndrome.Early diagnosis of talon cusps is crucial for the correct management and avoidance of complications. This case highlights the need for careful dental examination when treating children with syndromes, as new phenotypes that can have an effect on the dentition.
The Erosive Potential of Different Malt Drinks: An in vitro and in situ study
Authors: Çaglar Esber , Cildir Sule Kavaloglu , Sandalli Nuket 
Published: April 2015

Objectives: Whereas the potential effect of acidic drinks in the etiology of dental erosion is well recognized the role of malt drinks is unclear. The primary aim of the present study was to compare the in vitro erosive effect on enamel produced by different aromated malt drinks. A secondary objective was to compare their erosive effects in situ with those determined in vitro.
Materials and methods: To select the malt drink for the study in situ, six commercially available malt drinks were examined for erosive potential in vitro. The study in situ was a single centre, 2-period, 2-treatment crossover study to compare the erosive effect of a commercially available malt drink (Test), with that of natural spring water (Control), over 10 day periods on 10 healthy volunteers. Subjects wore upper removable appliances containing two human enamel specimens from 9 a.m. to 4 p.m. The regimen of intake of the drinks was 250 ml at midday. Measurements of enamel loss were made on samples after 5 and 10 days by profilometry.
Results: The in situ study showed a statistically significant difference in erosive potential between the test and control beverages. No specimen exposed to the control beverage displayed appreciable erosion. Erosion occurred with the test drink, but to a variable degree between subjects.
Conclusions: Malt drinks should be considered as potentially erosive as the results for enamel specimens exposed to the test beverage in the clinical study showed a degree of erosion that varied greatly between different participants. It is likely that under these conditions an increase in the degree of erosion would be observed in children and young people who consume malt drinks.

Authors: Shaughnessy Brian , Feldman Henry , Cleveland Robert , Sonis Andrew , Brown Julia , Gordon Catherine 
Published: April 2015

Purpose: To evaluate the dental and periodontal health of adolescents and young women with restrictive anorexia nervosa (AN), and relationship between bone mineral density (BMD) assessed by dual energy X-ray absorptiometry (DXA) and dental radiographs.
Study Design: Twenty-three young women, median age 17.6 years (range 14.4-27.2), were studied within three months of entering a clinical trial. DXA BMD measurements were obtained and subjects underwent a comprehensive dental examination, including panoramic and bitewing dental radiographs. Three observers assessed mandibular cortical width (MCW) in the mental foramen region on panoramic radiographs.
Results: Dental findings included very good to excellent oral hygiene. Gingival recession was evident in 10 participants (43%). Dental erosion was not seen and the mean decayed missing or filled teeth (DMFT) was 8.6. There was a weak positive correlation between BMD by DXA and MCW on radiographs. Conclusions:We report dental manifestations associated with restrictive AN, and the association between bone assessments by DXA and dental radiographs in this patient group. Despite subnormal DXA measurements in most patients, essentially all adolescents had a normal dental examination. Dental providers should be cognizant of the fact that many patients with eating disorders may not display the "classic" findings reported in the literature.
Ultramorphological Characterization of the Resin Dentin Interface – An in vitro Analysis of Nanoleakage Patterns of Dentin Adhesives
Authors: Neelakantan Prasanna , Sanjeev Kavitha , Rao CV Subba 
Published: April 2015

Aim and Design: The requirements of an effective dentin adhesive system include the ability to thoroughly infiltrate the collagen network and partially demineralized zone, to encapsulate the collagen and hydroxyapatite crystallites, to produce a well polymerized durable hybrid layer with high bond strengths. Microleakage and marginal percolation are the most detrimental factors thwarting the success of any restoration . However, the presence of leakage pathways, called nanoleakage have been observed in the hybrid layer,even in the absence of microleakage. The nanoleakage patterns of four dentin adhesives (Prime & Bond NT,AdheSE, Clearfil S3 bond and Fuji Bond LC) was compared using Scanning electron microscopy and Energy Dispersive Spectroscopy, by the silver nitrate penetration method.
Results and conclusion: The results indicated that etch and rinse adhesives showed the maximum nanoleakage followed by the self etch systems. The glass ionomer based bonding agents showed the least nanoleakage. It is extremely important to take nanoleakage as a consideration while choosing dentin adhesives, to ensure success of the restoration.

Published: April 2015

Objective: To compare the effect of 4 remineralizing materials on the incipient artificial carious lesion and its proximal sound enamel when used with fluoride dentifrice.Study Design: Models mimicking proximal contact were made, each of which was placed with an artificial carious specimen in contact with a sound enamel specimen. Each carious specimen was treated with one of four materials: glass ionomer cement (GIC), resin modified glass ionomer cement (RMGIC), 5000 ppm sodium fluoride (F-gel), and casein phosphopeptide amorphous calcium phosphate (CPP-ACP). The GIC and RMGIC specimens were thermocycled. Then all specimens were pH-cycled for 5 days with twice a day soaking in 1,000 ppm NaF dentifrice solution. Specimens were examined by polarized light microscopy and lesion area quantified by image analysis.Results: RMGIC significantly yielded smaller areas of lesion than CPP-ACP and GIC (p&lt;0.05). F-gel reduced more area of lesion than CPP-ACP significantly (p&lt;0.05). In the associated contact, RMGIC significantly reduced the area of lesion better than CPP-ACP (p&lt;0.05).Conclusions: The most effective remineralizing material in reducing the carious lesion areas was RMGIC followed by F-gel, GIC and CPP-ACP. The demineralization inhibitory effects on the associated sound contact enamel followed the same trend.

Authors: Boxberger NR , Brannon RB , Fowler CB 
Published: April 2015

The opinions and assertions expressed herein are those of the authors and are not to be construed as official or as reflecting the views of the Department of the Air Force or the Department of Defense.Objective: The ameloblastic fibro-odontoma (AFO) is an uncommon odontogenic tumor occurring in childhood with limited reported data on recurrence. The purpose of this AFO study was to review its clinicopathologic features, investigate treatment modalities and establish a recurrence rate. Study Design: The clinicopathologic features of 12 new cases of AFO were analyzed and compared with those of 208 cases from the literature, with special emphasis on the clinical behavior, treatment, and recurrence rate. Results:The average age was 9.4 (±6.7) years with a male-to-female ratio of 1.6:1. The mandible was the site of occurrence in 59.5%. The tumor most often presented radiographically as a unilocular mixed density lesion associated with the crown of an impacted tooth. Displacement of teeth, delayed eruption and bony expansion were commonplace. There were 5 recurrences among 68 cases with adequate follow-up for a recurrence rate of 7.4%. All recurrences were attributed to incomplete removal at the time of the initial surgery.Conclusions: The AFO is a childhood tumor most often affecting the posterior jaws and frequently causing bony expansion with profound affects on the dentition. Conservative surgical removal with extraction of the associated teeth is recommended. The established recurrence rate is less than 10%.
