Oral health management considerations for patients with sickle cell disease

Dental Caries in Children with Sickle Cell Disease and Its Association with the Use of Hydroxyurea and Penicillin Prophylaxis in Dar Es Salaam

Purpose

This comparative study sets out to report dental caries status among individuals with Sickle Cell Disease (HbSS) against those with sickle cell trait (HbSA) and those without the disease (HbAA) as controls. The study further assessed the impact of penicillin chemoprophylaxis and hydroxyurea use on dental caries among Sickle Cell Disease participants.

Methods

This was a comparative cross-sectional study in which 93 children aged 30 to 60 months were recruited. There were 60 participating children who had SCD (HbSS), 17 with SCD trait (HbAS) and 16 were without SCD or SC trait (HbAA). A questionnaire was used to record sociodemographic details including mean age in months and sex and on haemoglobin genotype for all the participants. Specifically, for the participants with HbSS, information on their whether they are taking hydroxyurea (HU), and penicillin chemoprophylaxis was recorded. To assess the prevalence of dental caries, clinical examination of all primary maxillary and mandibular teeth to determine the presence or absence of dental caries lesions was also recorded.

Results

A total of 1197 teeth from 93 children were examined, whereby, 45 (2.4%) of them had dental caries. The participating children with HbAA genotype (6.6%, N=21) had more dental caries than their HbSS counterparts (2.0%, N=24), while none of the participants with HbAS exhibited dental caries. Among the participants with HbSS, males and those who use HU were 3.79 and 3.07 times more likely to have dental caries than their counterparts, female and non-users of HU, respectively.

Conclusion

Dental caries was observed to be low among participants with HbSS when compared to those with HbAA. More research utilizing more robust methodologies is recommended.

Orofacial Manifestation and Dental Management of Sickle Cell Disease: A Scoping Review

Aims

Sickle cell disease (SCD) is an upcoming global health problem with rapid progress in therapy especially since 2017. However, systematic reviews found no clinical trials on the dental treatment of sickle cell disease (SCD). This article aims to outline the oral features of the sickle disease and discuss oral management strategies that can serve as guidelines for dental professionals. Material and Methods. A comprehensive literature review was conducted using PubMed, Google Scholar, and Web of Science. The search strategies were developed to cover publications from January 2010 to March 2020. With the help of keywords, multiple abstracts were identified. These abstracts were further reviewed, which included the information about the SCD manifestation, particularly about the oral health features. Based on all these articles and clinical experience, a narrative review was constructed, which summarizes all the aspects of the oral manifestation in people with SCD.

Results

The results of this study demonstrate that there is distinct evidence available, indicating the developmental enamel defect leading to hypoplasia and increasing susceptibility to dental caries. Another important result of this review found that people with SCD have a vaso-occlusive crisis in the microcirculation in the dental pulp leading to symptomatic and asymptomatic pulpal necrosis without any signs of odontogenic pathology in an apparently healthy tooth. The study also found that early detection, intervention, and prevention are crucial for improving oral health care, and involving a multidisciplinary approach plays an important role in managing people with SCD.

Conclusion

Patients with sickle cell disease have chronic overall health problems. The hematological disorder becomes their main concern and impaired oral health becomes secondary, increasing the risk for dental caries at the most. This paper broadly describes the oral manifestations of SCD, additionally; this paper also provides recommendations for better dental management of patients with SCD. Patients with SCD are often misjudged and, due to lack of knowledge and guidelines, dental providers are not able to provide adequate care. This paper attempts to highlight the essential measures to provide better dental care.

Predictors of dental complications post-dental treatment in patients with sickle cell disease

Objective

Our aim was to explore potential medical or dental indicators associated with dental complications and the utilization of emergency services in sickle cell disease (SCD), especially that clinical reports on adverse outcomes post‐dental treatment are scarce.

Materials and methods

A retrospective analysis of dental treatments of 47 eligible adults with confirmed SCD between May 2016 and October 2019. Logistic regression analysis was used whether clinical outcomes, course of dental treatment, and regularity of dental care are associated with dental complications after dental procedures and/or resulted in emergency care or hospital admissions.

Results

We identified a new, statistically significant association (p‐value = .01) between the number of prescription medications taken and complications (10%) after dental procedures. The most frequent dental procedures were tooth extractions (36%) and pain management (28%) during a non‐scheduled dental encounter (68%). The majority of cases did not participate in regular recall exams and periodical oral hygiene maintenance.

Conclusions

A higher number of prescription medications was associated with an increased risk of post‐dental complications in SCD patients. A thorough medical history, including a list of prescribed medications, and collaboration with the patient medical team are important to assess the risk of complications post‐dental procedures and the need for antibiotic prophylaxis according to the case complexity.

Evidence-based dental management in the new era of sickle cell disease: A scoping review

BACKGROUND

Sickle cell disease (SCD) is an emerging global health issue with rapid progress in therapy especially since 2017. However, systematic reviews found no clinical trials on dental treatment of SCD.

TYPES OF STUDIES REVIEWED

Using a scoping review approach, the authors examined citations from 13 national SCD guidelines and 10 books spanning 4 decades. The authors also searched the following databases: PubMed, Cumulative Index to Nursing and Allied Health Literature, ScienceDirect, Scientific Electronic Library Online, and GoogleScholar. Eligibility criteria included SCD, oral health care and dental treatment, related to oral and systemic health, original data, or observations.

RESULTS

Systemic treatment of SCD might have opposing effects on caries, perhaps explaining the conflicting results published. Malocclusion correlates with marrow expansion. Other unusual orofacial findings reflect ischemia. Of 86 full-text articles examined, only 1, a Brazilian esthetic dentistry study, was a randomized clinical trial. No disease-specific data were found on risk of developing bacterial endocarditis, safety of inhaled nitrous oxide, safety of epinephrine with local anesthetic, or the benefit of comprehensive oral health care.

PRACTICAL IMPLICATIONS

In SCD, oral health and systemic health could be strongly linked. Penicillin, vaccines, and hydroxyurea might impact caries and bone. The interaction of SCD treatments and oral health merit study.
