Impact of shortened dental arches on oral health‐related quality of life

This study described the prevalence of adults with shortened dental arches (SDA) in Brazil, specifically assessing the differences of oral health‐related quality of life [the prevalence and severity of oral impacts on daily performance (OIDP)] by dentition status. We analysed data from the 2010 National Survey of Oral Health in Brazil, including home interviews and oral examinations. The assessment of SDA used two alternative definitions: having 3–5 natural occlusal units (OUs) in posterior teeth or having 4 OUs in posterior teeth. Both definitions included having intact anterior region and no dental prosthesis. The analysis was weighted, and a complex sampling design was used. Negative binomial regression models assessed associations as adjusted for socio‐demographic conditions and dental outcomes. A total of 9779 adults (35–44 years old) participated in the study. A non‐negligible proportion had SDA: 9·9% and 3·8% for the first and second definition, respectively. Individuals with SDA (first definition) ranked higher in OIDP prevalence [count ratio (CR) 1·22; 1·09–1·36, 95% confidence interval (CI)] and severity (CR = 1·43; 1·19–1·72, 95% CI) than those with more natural teeth. This difference was not statistically significant when adjusted for socio‐demographic and dental covariates: OIDP prevalence (CR = 1·04; 0·92–1·17, 95% CI) and severity (CR = 1·09; 0·91–1·30, 95% CI). Analogous results were obtained when the second definition of SDA was adopted. These findings suggest that a considerable contingent of adults may function well without dental prostheses, despite having several missing teeth. This conclusion challenges the traditional approach of replacing any missing tooth and instructs the allocation of more dental resources to preventive, diagnostic and restorative services.     

Traumatic dental injuries in Brazilian children and oral health‐related quality of life

Background/Aims

Population‐based studies that investigate the impact of TDI on oral health‐related quality of life (OHRQoL) among school children and its association with socioeconomic factors are scarce and offer conflicting results. The aim of this study was to evaluate the impact of TDI on OHRQoL among school children and its association with socioeconomic status.

Materials and Methods

A cross‐sectional study was conducted with 588 12‐year‐old children enrolled in public and private schools in the urban areas in the city of Diamantina (southeastern Brazil). Clinical examinations were performed for the diagnosis of traumatic dental injury based on Andreasen's classification. The Child Perceptions Questionnaire (CPQ_11–14), which has been validated for the population in Brazil, was employed to evaluate oral health‐related quality of life. Socioeconomic status and overjet were also analyzed. Statistical analysis involved the chi‐square test and logistic regression.

Results

A total of 29.4% of the students exhibited some type of trauma to at least one tooth. A negative impact on oral health‐related quality of life was found in 53.1% of the sample. Traumatic dental injury was associated with a high impact on oral health‐related quality of life [OR = 1.61 (95% CI: 1.08‐2.39)] and overjet >3 mm [OR = 5.42 (95% CI: 3.66‐8.02)]. However, no statistically significant associations were found between TDI and socioeconomic status.

Conclusions

Prevalence of traumatic dental injury was high among the children who participated in the study, and it was associated with a high impact on oral health‐related quality of life as well as overjet >3 mm.     

Impact of oral diseases and disorders on oral‐health‐related quality of life of children with cerebral palsy

The aim of this study was to investigate the impact of oral diseases and disorders on the oral‐health‐related quality of life (OHRQoL) of children with CP, adjusting this impact by socioeconomic factors. Data were collected from 60 pairs of parents–children with CP. Parents answered the child oral health quality of life questionnaire (parental‐caregivers perception questionnaire and family impact scale) and a socioeconomic questionnaire. Dental caries experience, traumatic dental injuries, malocclusions, bruxism, and dental fluorosis were also evaluated. The multivariate adjusted model showed that dental caries experience (p < 0.001) and the presence of bruxism had a negative impact (p = 0.046) on the OHRQoL. A greater family income had a positive impact on it (p < 0.001). Dental caries experience and bruxism are conditions strongly associated with a negative impact on OHRQoL of children with CP and their parents, but a higher family income can improve this negative impact.     

Sleep bruxism and oral health‐related quality of life in children: A systematic review

Sleep bruxism (SB) is a masticatory muscle activity during sleep that can cause several consequences to the stomatognathic system. This systematic review investigated the impact of SB on oral health‐related quality of life (OHRQoL) of 0‐ to 6‐year‐old children. Literature search was undertaken through PubMed/MEDLINE, LILACS, Scopus, TRIP, Livivo databases, and grey literature. The search was conducted with no publication year or language limits. Two reviewers independently selected the studies, extracted the data and assessed the risk of bias. The quality of evidence was assessed using GRADE. From 185 potentially eligible studies, three were included in the review. All studies were conducted in Brazil, published between 2015 and 2017, and used the B‐ECOHIS instrument to evaluate OHRQoL. Two studies found no association between SB and OHRQoL, whereas one showed a significant negative impact of SB on the OHRQoL of children. SB was associated with respiratory problems, presence of tooth wear, dental caries, malocclusion as well as income and pacifier use. Risk of bias ranged from moderate to high, and the quality of evidence was judged as very low. The evidence is currently insufficient for definitive conclusions about the impact of SB on OHRQoL of children.     

Patterns of impaired oral health‐related quality of life dimensions

How dental patients are affected by oral conditions can be described with the concept of oral health‐related quality of life (OHRQoL). This concept intends to make the patient experience measurable. OHRQoL is multidimensional, and Oral Function, Oro‐facial Pain, Oro‐facial Appearance and Psychosocial Impact were suggested as its four dimensions and consequently four scores are needed for comprehensive OHRQoL assessment. When only the presence of dimensional impact is measured, a pattern of affected OHRQoL dimensions would describe in a simple way how oral conditions influence the individual. By determining which patterns of impact on OHRQoL dimensions exist in prosthodontic patients and general population subjects, we aimed to identify in which combinations oral conditions’ functional, painful, aesthetical and psychosocial impact occurs. Data came from the Dimensions of OHRQoL Project with Oral Health Impact Profile (OHIP)‐49 data from 6349 general population subjects and 2999 prosthodontic patients in the Learning Sample (N = 5173) and the Validation Sample (N = 5022). We hypothesised that all 16 patterns of OHRQoL dimensions should occur in these individuals who suffered mainly from tooth loss, its causes and consequences. A dimension was considered impaired when at least one item in the dimension was affected frequently. The 16 possible patterns of impaired OHRQoL dimensions were found in patients and general population subjects in both Learning and Validation Samples. In a four‐dimensional OHRQoL model consisting Oral Function, Oro‐facial Pain, Oro‐facial Appearance and Psychosocial Impact, oral conditions’ impact can occur in any combination of the OHRQoL dimensions.     

Impact of malocclusion on oral health–related quality of life in young adults

Objective:To assess oral health–related quality of life (OHRQoL) in young adult patients with malocclusion and to measure the association between orthodontic treatment need and OHRQoL.Materials and Methods:The study sample comprised 190 young adults aged 18 to 25 years who were attending orthodontic clinics at the Faculty of Dentistry. The Index of Orthodontic Treatment Need-Dental Health Component was used to measure orthodontic treatment need. Each participant was assessed for OHRQoL before and after treatment by using the Oral Health Impact Profile, Chinese version (OHIP-14).Results:Patients who had little or no, borderline, and actual need for orthodontic treatment represented 21.6%, 50.5%, and 27.9% of the total sample, respectively. OHRQoL (total OHIP-14 score and score for each domain) improved after treatment (P < .05). Significant differences in summary OHIP-14 scores were apparent with respect to orthodontic treatment need. Participants with high treatment need reported a significantly greater negative impact on the overall OHRQoL score. The greatest impact was seen in the psychological discomfort domain and the psychological disability domain.Conclusion:Malocclusion has a significant negative impact on OHRQoL. This is greatest for the psychological discomfort and psychological disability domains. The orthodontic treatment of malocclusion improves OHRQoL of patients.
