The impact of osteogenesis imperfecta severity on oral health-related quality of life in Spain: a cross-sectional study.

BACKGROUND: Osteogenesis imperfecta (OI) affects dental and craniofacial development; therefore, it can influence oral health-related quality of life (OHRQoL). The objective of this study was to explore the influence of the severity of OI on OHRQoL in adults older than eighteen years residing in Spain. METHOD: Adults with OI were recruited from the Spanish Association of Crystal Bone (AHUCE) foundation. OHRQoL was evaluated using the Spanish version of the Oral Health Impact Profile questionnaire (OHIP-14sp), oral hygiene habits, and a dental care survey. Clinical and radiological dental examinations were performed to evaluate the patients' oral conditions. RESULTS: A total of 65 adults (n = 46 females) aged between nineteen and sixty-two years who were diagnosed with OI and classified as type I, III, and IV (n = 20, 14, and 31, respectively) participated in this research. The total OHIP-14sp scores were significantly greater (worse) for type III (23 [SD = 10]) and type IV (21.4 [SD = 12]) than for type I (13.8 [SD = 6]) (P < 0.05). The negative impact of OHRQoL was due to the association of type III OI with all domains except for the handicap domain, while type IV OI was associated with the physical disability, social disability, and handicap domains (P < 0.05 for all). CONCLUSION: The severity of OI negatively impacted OHRQoL in adults. This association was statistically significant.

Dental treatment under general anesthesia in patients with severe intellectual disability at the Gregorio Marañón General University Hospital: a 10-year retrospective study.

OBJECTIVES: There is a high demand for dental treatment in a hospital setting for patients with severe intellectual disability (ID), due to their inability to cooperate. The objective was to determine the types of dental treatment carried out on patients with severe ID, as well as the possibility of performing clinical and radiographic examinations prior to treatment and to identify their characteristics. METHOD AND MATERIALS: A retrospective observational study was performed, based on the medical histories of patients with severe ID or a disability included in the portfolio of dental services of Community of Madrid, who underwent dental treatment at the Stomatology Service of the Gregorio Marañón General University Hospital from the year 2009 to 2019. Data on age, sex, etiology of disability, and dental treatment were obtained. RESULTS: A total of 1,845 patients were included. The type of disability in the majority of cases was unknown, followed by encephalopathy, cerebral paralysis, and Down syndrome. In total, 8,439 dental extractions were performed on 1,548 patients (83.9%). Clinical and radiographic exploration were carried out on 874 patients (47.4%). CONCLUSIONS: Ultrasonic scaling was the most frequently performed treatment in patients. Dental extractions were the next most common treatment. An increase in age showed a higher demand for surgical procedures and extractions. Over half of the patients (52.6%) did not tolerate clinical or radiographic examinations.

Morphological Study of Dental Structure in Dentinogenesis Imperfecta Type I with Scanning Electron Microscopy.

Background: Dentinogenesis imperfecta type I (DGI-I) is a hereditary alteration of dentin associated with osteogenesis imperfecta (OI). Aim: To describe and study the morphological characteristics of DGI-I with scanning electron microscopy (SEM). Material and methods: Twenty-five teeth from 17 individuals diagnosed with OI and 30 control samples were studied with SEM at the level of the enamel, dentin-enamel junction (DEJ) and four levels of the dentin, studying its relationship with clinical-radiographic alterations. The variables were analysed using Fisher's exact test, with a confidence level of 95% and asymptotic significance. Results: OI teeth showed alterations in the prismatic structure in 56%, interruption of the union in the enamel and dentin in 64% and alterations in the tubular structure in all of the cases. There is a relationship between the severity of OI and the morphological alteration of the dentin in the superficial (p = 0.019) and pulpar dentin (p 0.004) regions. Conclusions: Morphological alterations of the tooth structure are found in OI samples in the enamel, DEJ and dentin in all teeth regardless of the presence of clinical-radiographic alterations. Dentin structural anomalies and clinical dental alterations were observed more frequently in samples from subjects with a more severe phenotype of OI.
