Oral health-related quality of life before hematopoietic stem cell transplantation.

OBJECTIVES: This study was planned to evaluate the impact of oral health on the quality of life (QoL) of patients undergoing hematopoietic stem cell transplantation (HSCT). MATERIAL AND METHODS: We assessed 200 patients divided into two paired groups: 100 patients prior to HSCT (SG) and 100 healthy volunteers (CG). We applied the Oral Health Impact Profile instrument, which is based on the biopsychosocial problem gradation of World Health Organization (WHO) and relates oral health problems with QoL according to seven dimensions. RESULTS: Fourteen patients in SG were referred for extraction of one to eight teeth, mostly due to deep caries with risk of pulpal infection and possible spread of infection via blood (r = 0.59, p = 0.000). The presence of severely compromised teeth by extensive decay correlated with Oral Health Impact Profile (OHIP-14). The Mann-Whitney test showed a significant difference between SG and CG in the following dimensions: functional limitation (p < 0.001), physical pain (p = 0.025), physical disability (p = 0.016), and social disability (p = 0.01). CONCLUSIONS: The impact of oral health on QoL of onco-hematologic patients is weak but is greater as compared to healthy ones. Nevertheless, a significant impact is seen in patients with severely compromised teeth. CLINICAL RELEVANCE: The negligence of oral care, proper hygiene, and the search for dental care may increase the risk for local and systemic infections.

Ultrasonography as a complementary exam in the diagnosis of oral arteriovenous malformation.

The Doppler ultrasonography (DU) in cases of arteriovenous malformations (AVMs) is not widely use by dentists and there are a lack of information on the topic in the literature. AVM is common in the region of the head and neck and are commonly confused with hemangiomas (congenital). Appropriate classification is essential for therapeutic decision. The diferential diagnosis is based on clinical history, diascopy, and, if necessary, diagnostic imaging. This article present two cases of oral AVM in which DU was crucial in detecting a venous and/or arterial component in purplish lesions in the tongue and buccal mucosa, with positive diascopy. In our cases, after DU, we found a predominance of blood component within the lesion and therefore both patients were referred to the head and neck surgeon for surgical removal of the lesion. Only in the presence of a venous component does outpatient treatment become feasible. Given the predominance of the arterial component, outpatient procedures are contraindicated. Therefore DU is an important supplementary test, being of great importance in the clinical decision and treatment plan for oral AVMs and should become a routine part of the dentist front of vascular lesions of medium to large size.

Unusual bilateral dentigerous cysts in a nonsyndromic patient assessed by cone beam computed tomography.

In the absence of syndromes, bilateral dentigerous cysts (DC) located on the jaws are unusual. In English based language literature review, we only found eight reports of nonsyndromic bilateral dentigerous cyst associated with mandibular third molars. Therefore, we report the unusual occurrence of sizable nonsyndromic bilateral DC associated with mandibular impacted third molars in a 42-year-old Caucasian woman. The lesions were assessed by cone beam computed tomography (CBCT) the right lesion showed approximately 23.64 mm and the left one, 16.57 mm diameter, both located intimately next to the mandibular canal. Bilateral surgical enucleation, related teeth excision of both third molars and plate for fixation placement on the right and bigger lesion, under general anesthesia was the final treatment choice. Clinical, radiographic and histopathological features confirmed diagnose of bilateral dentigerous cyst. Now-a-days, the patient is on 18 months radiograph follow-up with favorable osseous formation with no evidence of recurrence of the cysts.
