Diagnosis and management of hemangiomas and vascular malformations of the head and neck

Oral Diseases (2010) 16 , 405–418 Vascular anomalies are congenital errors in vascular development. They frequently involve the head, neck, and oral cavity. Subdivided into vascular tumors (hemangiomas) and vascular malformations, vascular anomalies remain poorly understood. However, growing interest and recent advances in the diagnosis, management, and molecular characterization of these lesions are improving treatment strategies. The role of the multidisciplinary team cannot be overstated. This review provides both basic and up‐to‐date knowledge on the most common vascular anomalies encountered by physicians and practitioners. Because treatment options for vascular anomalies are widely variable and often debated, this report aims to provide a comprehensive approach to these lesions based upon current concepts and practical clinical experience.

Colour and translucency of opaque-shades and body-shades of resin composites

The purpose of this study was to evaluate the optical properties--not only the translucency but also the colours--of opaque-shade resin composites. The CIELAB parameters (L*, a* and b*) of disks of A2 and opaque A2 (OA2) shades of Charisma (Heraeus-Kulzer), Solare (GC) and Filtek Supreme (3M) were evaluated on backings of black, white and the material itself to calculate the translucency parameter (TP) and the colour differences (delta E*) between A2 and OA2. A two-way analysis of variance (anova) for the TP indicated a less statistically significant TP value in the OA2 shade than the A2 shade for all products. As for the products, Charisma showed a statistically greater TP value than the other two products. Regarding the delta E* between A2 and OA2, all the products revealed clinically perceptible colour differences (delta E* > 3.3). Hence, we must take the colour differences of opaque-shade resin composites into consideration, as well as the translucency of the materials, for a clinically acceptable colour match of the restoration.

Assessment and comparison of phagocytic function and viability of polymorphonuclear leukocytes in saliva of smokers and non-smokers

OBJECTIVES

Tobacco use is one of the most important public health problems worldwide. It is also linked to impairment of normal immunologic surveillance and defence mechanism of polymorphonuclear leukocytes. Tobacco smoke and its components have been seen to affect the phagocytic ability and viability of polymorphonuclear leukocytes suggesting the pathogenesis of tobacco induced oral diseases. Aim of this study was to assess and compare the phagocytic function and viability of polymorphonuclear leukocytes in saliva of smokers and non smokers.

DESIGN

The study comprised of 35 smokers and 35 non-smokers, age matched. Saliva was collected by rinsing method and the polymorphonuclear leukocytes were separated. Phagocytic activity was determined by using latex spheres as targets. Cell viability was measured using trypan blue stain.

RESULTS

Salivary polymorphonuclear leukocytes in smokers showed significant reduction in the phagocytic activity by ingesting few latex spheres when compared to the non-smokers. The viability of these cells in saliva of smokers was significantly reduced.

CONCLUSIONS

The present study revealed reduced phagocytic activity and viability of salivary polymorphonuclear leukocytes in smokers compared to non-smokers. These findings indicate that smokers are more prone to gingival, periodontal and other oral diseases. Thus indicating that the health care professionals should encourage smoking cessation as an aid in preventing oral diseases.

Combined effects of NaF and SLS on acid- and polysaccharide-formation of biofilm and planktonic cells

Bacteria grow preferentially attached to surfaces embedded in an exopolysaccharide matrix to form biofilms. In this mode of growth, bacteria often show reduced susceptibility to antimicrobials. The aim of this study was to investigate whether the combination of NaF and the detergent sodium lauryl sulphate (SLS) could result in additive effects on acid formation by planktonic and biofilm cells, as well as on extracellular polysaccharide formation. An additive inhibitory effect on Streptococcus mutans acid formation was observed, both in planktonic and biofilm cells. In dental biofilms, SLS alone and in combination with NaF reduced acid formation. Extracellular polysaccharide formation by S. mutans and saliva was reduced by SLS alone and in combination with NaF. In dentifrices and mouthrinse solutions, NaF and SLS are often present in combination. It remains to be determined whether an additive effect on acid formation may also occur in dental biofilms under different concentrations from those used in the present study, and whether the effects may be selective for certain bacterial species.     

Effects of zinc and copper on adhesion and hemagglutination of Prevotella intermedia and Prevotella nigrescens

This study investigated the mechanism of protein attachment to the surface of the putative periodontal pathogens Prevotella intermedia and Prevotella nigrescens in artificial gingival crevicular fluid, and ways to increase protein attachment to the bacterial cells. The effects of cations on protein attachment, bacterial adhesion, and hemagglutination were examined, and cation-binding components on both bacterial species were identified. The presence of cations, especially zinc, copper and cerium, increased attachment of human serum proteins to both bacterial species. In contrast, the presence of hydrophobic inhibitors or sugars had little effect. Protein attachment was reduced by heat treatment of the bacterial cells. Pretreatment of bacteria with human serum proteins inhibited adhesion of both species to buccal epithelial cells and hemagglutination. These effects were enhanced by the presence of zinc and copper during pretreatment. Using a chelating column, specific zinc- and copper-binding proteins were identified on the surfaces of both bacterial species.     

Impact of moderate and severe hypodontia and amelogenesis imperfecta on quality of life and self-esteem of adult patients

ObjectivesThe objective of this study was to investigate the impact of moderate and severe hypodontia and amelogenesis imperfecta on the quality of life and self-esteem of affected adult patients.MethodsForty one adult patients (aged 18–45 years) with clinical and radiological diagnoses of moderate to severe hypodontia and twenty seven patients diagnosed with amelogenesis imperfecta were age and gender matched with a control group of patients attending for routine dental care. Subjects completed the Oral Health Impact Profile [OHIP-49] and Rosenberg Self Esteem Scale. A paired t-test was used to analyse data; the test alpha level was set at P ≤ 0.05.ResultsThe results for hypodontia patients were significantly different from controls in six out of the seven OHIP-49 domains, the exception being the Handicap domain. Total scores were also significantly different between the two groups (P = 0.003). Self-esteem was not significantly different between the two groups (P = 0.98).For amelogenesis imperfecta patients the results were significantly different from control patients in four out of the seven domains of the OHIP-49 and also in the total scores (P = 0.01). When self-esteem was investigated there was no significant differences between the two groups (P = 0.92).ConclusionsModerate to severe hypodontia and amelogenesis imperfecta have marked negative impacts on the Oral Health Related quality of life of this patient population relative to controls. However, self-esteem was not significantly affected.
