Malocclusion and treatment need in children and adolescents with sickle cell disease

Comparison of oral health status, oral hygiene management behaviours and satisfaction of patients with fixed orthodontic appliance and clear aligner: A quasi-experimental design

OBJECTIVES

This study aimed to determine the overall oral health statuses of patients with fixed orthodontic appliance and clear aligner, as well as their oral hygiene management behaviours and satisfaction.

METHODS

We selected 40 participants (20 each with fixed orthodontic devices and clear aligners) who visited a dental clinic. We conducted a survey to determine the oral hygiene management behaviours of the subjects and their satisfaction with their orthodontic treatment. Three measurements were also conducted at 4-week intervals to determine the oral health statuses of the subjects.

RESULTS

The Löe and Silness gingival index of patients with fixed orthodontic appliances indicated moderate gingivitis (1.1 ± 0.3), and those with clear aligners had mild gingivitis (0.6 ± 0.4) (p < 0.001). The modified O'Leary index also indicated that the degree of dental plaque deposition in the oral cavity was lower in patients treated with a clear aligner (43.0 ± 18.2 points) than in those treated with a fixed orthodontic (28.1 ± 10.9 points) (p = 0.004). Regarding oral hygiene management, the fixed orthodontic group received scaling more frequently (p = 0.006), received more oral health education (p < 0.001) and had a longer brushing time (p = 0.008) than the clear aligner group. No significant difference was observed in satisfaction between the fixed orthodontic appliance and the clear aligner.

CONCLUSIONS

Regarding the oral health status by orthodontic appliance type, the clear aligner group had the advantages of reduction in dental plaque attachment and gingival health. The fixed orthodontic group exhibited better oral hygiene management behaviours. Satisfaction with orthodontic treatment was found to be similar for the two device types.

Minor physical anomalies including palatal rugae pattern and palatal dimensions in children with sickle cell disease: A cross-sectional analytical study

Background

Sickle cell disease (SCD) is the most common hereditary hemoglobinopathy, which delays growth leading to an altered skeleton and craniofacial pattern. Palatal rugae patterning has been considered the regulator of the development of the palate. The purpose of the research work was to study the morphology of the palate, rugae pattern, and its dimensions in SCD children and compare them with healthy normal children, and to evaluate its role as minor physical anomalies (MPAs).

Methods

A cross-sectional case-control study was designed as per STROBE guidelines. The sample comprised 50 children diagnosed with sickle cell disease (Group SCD) and 50 normal healthy children as control (Group C) belonging to the same age group (10-18 years). Dental impressions were made, followed by the pouring of dental casts. The length of the palatal rugae was measured and categorized into primary (>5 mm), secondary (3 mm-5 mm), and fragmentary rugae (<3 mm). The shape of each primary palatal rugae was identified and categorized as curved, wavy, straight, circular and non-specific. Linear and angular measurements of the palatal rugae patterns and palatal dimensions (width, height, area) were measured and recorded.

Results

The total number of palatal rugae and fragmentary rugae was lesser in Group SCD than in Group C (p < 0.05). The depth of the palate was significantly increased, whereas the area of the palate significantly decreased in Group SCD.

Conclusions

The children with SCD showed distinctive palatal rugae patterns and dimensions when compared with normal healthy children that can be attributed as potential MPAs for sickle cell disease. Children with SCD had an under-developed palatal rugae pattern with a deep, narrow and small palate when compared to healthy children.The dimensions of the palatal rugae pattern in SCD showed reduced distance between the incisive papilla and the first and last rugae, indicating a further decrease in the anteroposterior dimensions of the palate. These findings may aid in the early diagnosis and prevention of malocclusion in children with SCD by appropriate interceptive orthodontic treatment.

Prevalence of orofacial alterations in patients with sickle-cell disease: Systematic review and meta-analysis

OBJECTIVE

The aim of this study was to identify the prevalence of orofacial alterations in sickle-cell disease (SCD) and to compare it with the general population.

STUDY DESIGN

This review followed the Preferred Reporting Items for Systematic Reviews and Meta-Analyses 2020 guidelines. The search was conducted on PubMed, Embase, Scientific Electronic Library Online, Web of Science, Cochrane Library, gray literature, and references of the included articles.

RESULTS

A total of 770 records were found, and 28 studies were selected. In SCD, the prevalence of decreased bone density was 57% (95% CI: 35%-80%), with Q: P < .01 and I² = 95%; for stepladder pattern was 30% (IC: 13%-47%), Q: P < .01 and I²: 93%; for delayed eruption was 20% (95% CI: 6%-34%), with Q: P < .01 and I² = 86, Q: P < .01 and I² = 99%; and for malocclusion, 66% (95% CI: 39%-92%), Q: P < .01 and I² = 98%. A high risk of bias was observed in relation to the sample size of the studies. A limited number of articles compared the prevalence of orofacial alterations in patients with SCD and healthy individuals.

CONCLUSIONS

Decreased bone density, malocclusion, orofacial pain, tooth necrosis, eruption delay, periodontal disease, and neuropathies may be present in patients with SCD with variable prevalence.

A Cephalometric Evaluation and Comparison of Skeletal, Dentoalveolar, and Soft Tissue Changes Brought about by the Forsus Fatigue Resistant Device and PowerScope Fixed Functional Appliance

Background:

Though studies have been conducted on the PowerScope, not many researches are available in the literature which compare its effects with other fixed functional appliances. Therefore, the aim of our study was cephalometric evaluation and comparison of the skeletal, dentoalveolar, and soft tissue changes brought about by the Forsus Fatigue Resistant Device and PowerScope appliance.

Materials and Methods:

Pre and Posttreatment cephalometric records of 20 patients with Class II Division 1 malocclusion treated with fixed functional appliances (Forsus Fatigue Resistant Device and PowerScope) were compared. Values of various cephalometric parameters were used to evaluate the skeletal, dental, and soft tissue changes. Wilcoxon signed-rank test (intragroup comparison) and Mann–Whitney U test (intergroup) were used to see significant differences in the parameters ( P ≤ .05).

Results:

Both the appliances were successful in correcting the Class II discrepancy. Skeletal changes were seen significantly in both the groups, though they were more in the Forsus patients. Dentoalveolar changes were predominantly seen in PowerScope patients. Also, an improvement in soft tissue profile was seen in both the groups.

Conclusion:

From our study, we concluded that the PowerScope and the Forsus Fatigue Resistant Device are equally good options for the correction of skeletal Class II malocclusion due to a retrognathic mandible, as they achieve changes in all the three aspects: skeletal, dentoalveolar and soft tissue.

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.

Oral Manifestation of Systemic Diseases

The US Surgeon General's report Oral Health in America highlighted ways in which oral health and systemic conditions are associated with each other. An oral examination can reveal signs and symptoms associated with systemic diseases. In this article, multiple systemic diseases including but not limited to viral and immune modulated conditions and associated oral symptoms are discussed.

Malocclusion and Craniofacial Characteristics in Saudi Adolescents with Sickle Cell Disease

Background

Sickle cell disease can result in dentofacial abnormalities. However, in Saudi Arabia, there are limited data with respect to orthodontic manifestations in patients with sickle cell disease.

Objective

To determine the malocclusion and craniofacial characteristics in sickle cell disease adolescents and compare them with that of controls from the Eastern Province of Saudi Arabia.

Methods

This comparative cross-sectional study included 112 Saudi patients with sickle cell disease, aged 12-18 years, and 124 age-matched Saudi controls from three major hospitals in Al Khobar and Dammam, Saudi Arabia. The Dental Aesthetic Index was used to assess malocclusion and orthodontic treatment needs. Digital lateral cephalometric radiographs were recorded for each patient and control, and its analysis included linear and angular measurements.

Results

The prevalence of malocclusion was 87.5% in sickle cell disease patients and 54% in controls (P = 0.0001). The percentage of sickle cell disease patients with severe malocclusion that required orthodontic treatment was higher than that of controls (37.5% vs. 26.6%). In the sickle cell disease cohort, incisal segment crowding (72.4%), overjet (67.3%) and maxillary misalignment in the anterior segment (56%) were the most prevalent types of malocclusions and were significantly higher than that of controls (P < 0.05). About 38% and 67% of the sickle cell disease patients had openbite and posterior crossbite, respectively, compared with 19.3% (P = 0.001) and 37.1% (P = 0.0001) of controls, respectively. Cephalometric analysis showed that SNA (86.7°) and ANB (9.9°) angles were significantly higher in sickle cell disease patients than in controls (81.5° and 2°, respectively). In addition, lower central incisor-to-Frankfort horizontal plane (55°) and interincisal angles (121.5°) were significantly lower in sickle cell disease patients than in controls.

Conclusion

Adolescents with sickle cell disease had a higher prevalence of malocclusion and greater orthodontic treatment needs than controls. Similarly, they had greater incisal crowding, overjet, openbite and posterior crossbite and demonstrated higher SNA, ANB and lower interincisal angles than controls. The findings of this study suggest that adolescents with sickle cell disease should be provided frequent dental examinations and early orthodontic treatment to improve their oral health, and thus quality of life.
