Acid erosion: an increasingly relevant dental problem. Risk factors, management and restoration
(2017) Milosevic, Alex
Abstract: A review of risk factors and management of acid erosion. Particular emphasis is placed on the use of direct composite as a reversible and relatively straightforward restorative option.
Direct Placement Composite: the Treatment Modality of Choice to Restore the Worn or Eroded Dentition in Primary Dental Care.
(2016) Milosevic, Alex
Abstract: Tooth wear is increasing in severity and prevalence, partly because of an ageing population and partly because of modern lifestyles. Management of the worn dentition with 'full mouth rehabilitation' is outmoded. This clinical paper aims to review the literature on composite restorations and give general dental practitioners the confidence to restore the worn dentition with dental composite. Composite is a versatile and widely available material that can be successfully applied within the existing occlusal vertical dimension (OVD) or at an increased OVD using a Dahl approach. Cases illustrate what is achievable, and clinical tips will help dentists optimise their results.
The effect of layered double hydroxide on fluoride release and recharge from a commercial and an experimental resin varnish
(2021) Tejani, Tameeza Hassanali; Milosevic, Alex
Objectives: Layered Double Hydroxide (LDH) is capable of fluoride anion exchange and release. This study investigated the effects of incorporating ZnAl-LDH in commercial and experimental dental varnishes, on fluoride release and re-release after charging in NaF. Methods: Five discs of each material (commercial ClinproXT varnish and experimental light cured resin varnish), with and without 9%ZnAl-LDH were immersed and agitated in deionised water (DW) at 37◦C. A fluoride ion selective electrode measured fluoride release in DW daily over two-weeks. At 3, 6, 9 and 12 days the discs were recharged in 15 ml 0.05 M NaF solution (37◦C) for five minutes followed by immersion in DW. Energy dispersive X-rayspectra (EDS), weight changes and SEMs were performed on discs, before and after each cycle. Results: Evidence of ZnAl-LDH was confirmed by the presence of peaks for zinc and aluminium in EDS spectra. Cumulative fluoride and mean fluoride released between Clinpro, Clinpro + LDH and resin were significantly different (ANOVA, Tukey’s HSD post-hoc test, p< 0.001) except between the resin and resin + LDH. Mean fluoride concentrations differed significantly after every recharge between Clinpro, Clinpro + LDH and resin, but not betweenthe resin and resin + LDH (p < 0.01). The weights and SEMs of the experimental resins +/-LDH, appeared to be stable whilst the weights of Clinpro samples +/−LDH, fluctuated and fragmented. Significance: ClinproXT and experimental resin containing ZnAl-LDH recharged with fluoride did not significantly increase fluoride release compared to the unmodified materials. However, all LDH-F incorporated materials demonstrated fluoride recharging properties which appear beneficial to dentistry and thus further work is required to improve these properties.
The Restoration of Severe Generalized Dental Erosive Wear using Direct Composite: A Case Report
(2021) Alhammadi, Sara; Milosevic, Alex
Introduction: This case report describes a conservative restorative approach in the management of severe generalized tooth wear. Case report: The male, aged 57 years, was mainly concerned with the poor appearance of his teeth with short and discolored upper incisors. History revealed that he suffered from gastric reflux for 25 years, for which he was prescribed Ranitidine and was advised to self-medicate with cider vinegar. Furthermore, he divulged that he ground his teeth at night and during the day and had a high intake of carbonated cola drinks. On examination, dentine was exposed in several areas, and to a significant extent, on the incisal aspects of the lower incisors, the palatal surfaces of the upper incisors, and the occlusal surfaces of the molars. Mandibular tori were present. The primary diagnosis was erosive tooth wear with elements of attrition and abrasion. The intervention included dietary advice and restoration with direct composite resin at an increased occlusal vertical dimension of 1.5mm on the retruded axis. The patient reported no functional problems and was pleased with the aesthetic result. Conclusion: Vinegar is promoted to have health benefits, especially with respect to glucose response, but the dental implications are overlooked. This paper reviews the literature on vinegar as a medicament and considers its role as a co-factor for erosion in this case. The clinical steps used to restore the eroded dentition by direct composite are described. The use of this approach is a safe, conservative and successful treatment option without recourse to complex and biologically costly conventional alternatives. The application of direct composite in tooth wear cases meets the European consensus requirements.
