Dentomaxillofacial manifestations of Gaucher's disease: preliminary clinical and radiographic findings

Gaucher: A Systematic Review on Oral and Radiological Aspects

Background and Objectives: Gaucher disease (GD) is a lysosomal storage disorder with the genetic autosomal recessive transmission. Bone involvement is a prevalent finding in Gaucher disease. It causes deformity and limits daily activities and the quality of life. In 75% of patients, there is bone involvement. This review aims to evaluate the principal findings in the jaw by a Cone-beam computed tomography (CBTC) and X-ray orthopantomography; Materials and Methods: PubMed, Web of Science, Lilacs and Scopus were systematically searched until 31 December 2022. In addition, a manual search was performed using the bibliography of selected articles and a Google Scholar search. Clinical studies were selected that considered principal radiographic findings in radiography in a group of patients affected by GD. Results: Out of 5079 papers, four studies were included. The main findings are generalized rarefaction and enlarged narrow space, anodontia. Conclusions: The exact mechanism of bone manifestation is probably due to the infiltration of Gaucher cells in the bone marrow and, consequently, the destruction of bone architecture. All long bones are a potential means of skeletal manifestation. The jaw is more affected than the maxilla, and the principal features are cortical thinning, osteosclerosis, pseudocystic lesions, mental demineralization, flattening in the head of the condyle, effacement of anatomical structures, thickening of maxillary sinus mucosa. The dentist plays a crucial role in diagnosing and treating these patients. Sometimes the diagnosis can be made by a simple panoramic radiograph. All long bones are affected, and the mandible is particularly involved.

Clinical and radiological evaluation of dentomaxillofacial involvement in Type I Gaucher disease

OBJECTIVES

This study aimed to evaluate the oral findings and dentomaxillofacial involvement of patients diagnosed with Type I Gaucher Disease (GD), and to compare these findings with the control group.

METHODS

A total of 32 patients, 5 males, and 11 females in both the study (range 19-60, mean age 34.56) and control group (range 18-49, mean age 34.63) were included in the study. The file records of all patients obtained in the first evaluation were examined, and the hematological, visceral, and bone examination findings were recorded. Subsequently, oral examinations were performed for oral findings and dentomaxillofacial involvement, and radiological examinations were performed in panoramic images and cone-beam computed tomography (CBCT) images.

RESULTS

There was mandible involvement in 9 (56.3%), and involvement in both jaws in 4 (25.0%) of the patients with Type I GD. According to the CBCT findings, generalized rarefaction in 10 (62.5%) patients, enlarged marrow spaces in 12 (75.0%) patients, thinning of the lamina dura in 10 (62.5%) patients, and loss in the cortical borders of the mandibular canal in 7 (43.8%) patients were among the common radiographic findings. When the control and study group were compared, in panoramic images, a significant difference was found in terms of generalized rarefaction and enlarged marrow spaces, while significant differences were found in CBCT images regarding generalized rarefaction, enlarged marrow spaces, loss in the cortical margins of the mandibular canal and widening in the periodontal ligament space.

CONCLUSIONS

The roadmap for the diagnosis of Gaucher lesions in the jawbones includes a comprehensive medical history and a clinical and radiological examination. In conclusion, dentists should be familiar with the dentomaxillofacial findings of GD and be aware of possible oral and dental complications that may develop.

Jaw involvement in Gaucher disease: a not-so-uncommon feature of a rare disease

Gaucher disease is an inborn error of metabolism resulting from the deficiency of the enzyme glucocerebrosidase and consequent accumulation of glucocerebroside within the lysosomes of macrophages. The clinical presentation is very diverse, depending on the age of onset and the severity of the disease, and results from the progressive infiltration of lipid-laden cells in various organs. Common manifestations of Gaucher disease include enlarged liver and/or spleen (hepatosplenomegaly), bone marrow disease (pancytopenia) and bone abnormalities, which are extremely variable and can affect multiple skeletal sites. While bone involvement of long bones and vertebrae is a well-recognised feature of Gaucher disease, jawbone involvement is less commonly noted. Here, we describe a case of a 63-year-old patient with type 1 Gaucher disease with a history of long-term use of bisphosphonates and who had presented with dental pain, with subsequent investigations confirming the radiological features of jaw involvement in Gaucher disease, including periodontal disease.

Jaw bones' involvement and dental features of type I and type III Gaucher disease: a radiographic study of 42 paediatric patients

PURPOSE

Gaucher disease (GD) is a lysosomal storage disease caused by an autosomal recessive inherited deficiency of the lysosomal enzyme glucocerebrosidase. The aim of this study is to describe jaw bones' involvement and dental radiographic features in paediatric Gaucher disease patients (type I and type III).

METHODS

The study population of this case-control study included: 42 Gaucher patients (study group) and 84 medically free children (control group). The radiographic images of both groups were analysed for the following findings: generalised bone rarefaction, localised rarefaction and enlarged bone marrow spaces, thinning of cortex, pseudocystic radiolucent lesions, anodontia and dental anomalies. Dental age assessment of Gaucher patients using the Demirjian's method was also performed.

RESULTS

Generalised rarefaction showed almost similar percentages in both types of Gaucher disease cases. Localised rarefaction was noted in 30.77% and 18.75% of Gaucher disease type III and type I, respectively. Pseudocystic radiolucent lesions, thinning of cortex, anodontia and dental anomalies were more prevalent in type III Gaucher patients. The mean chronological and mean dental ages in both sexes of Gaucher patients were not statistically significant.

CONCLUSION

Thinning of cortex, localised rarefaction and generalised rarefaction are the most common jaw bone findings in Gaucher patients.
