Relationship Between Orthodontic Treatment Need and Oral Health-Related Quality of Life among 11⁻18-Year-Old Adolescents in Lithuania

Clinical parameters and inflammatory biomarkers among patients with multibracket appliances: a prospective clinical trial

BACKGROUND

Aim of the presented study was to investigate changes in clinical parameters and active matrix metalloproteinase-8 (aMMP-8) levels in gingival crevicular fluid of patients before and during treatment with multibrackets appliances.

METHODS

Fifty-five adolescents scheduled for the treatment were included. Clinical parameters and subgingival samples were obtained at six time points: 1 week before appliance insertion (T0), 3 (T1), 6 (T2) weeks, 3 (T3), 6 (T4) months, and 1 year (T5) after that. Gingival index and plaque index were assessed to evaluated changes on the clinical status. Subgingival samples were collected to analyze changes in aMMP-8.

RESULTS

Scores for gingival and plaque index increased after bracket insertion. The gingival index increased from T2 (p < 0.05) until T5 (p < 0.0001). Plaque index also increased, reaching its maximum peak at T3 (p < 0.05). Moreover, an increase of aMMP-8 levels (p < 0.05) was noted. There was no significant between upper and lower jaws.

CONCLUSIONS

Treatment with multibracket appliances in adolescents favors dental plaque accumulation and may transitionally increase gingival and plaque index and aMMP-8 levels leading to gingival inflammation, even 1 year after therapy began.

The Effect of Third Molars on the Mandibular Anterior Crowding Relapse-A Systematic Review

The present systematic review updates the evidence on wisdom teeth contributing to lower incisor crowding following orthodontic treatment. Relevant literature was searched on online databases, namely Pubmed, Scopus, and Web of Science, up to December 2022. Eligibility criteria were formulated using the PICOS approach and PRISMA guidelines. Eligible research included original clinical studies involving patients previously being treated orthodontically with permanent dentition at the end of treatment, regardless of sex or age. The initial search yielded 605 citations. After considering eligibility criteria and removing duplicates, only 10 articles met the criteria for inclusion. The risk of bias of eligible studies was evaluated using the Cochrane Handbook for Systematic Reviews and Interventions tool. The majority were highly biased, mainly regarding allocation concealment, group similarity, and assessment blinding. The vast majority did not report statistically significant associations between the presence of third molars and crowding relapse. However, a minor effect has been suggested. Seemingly, there is no clear connection between mandibular third molars and incisor crowding after orthodontic treatment. The present review did not find adequate evidence to advocate preventative removal of the third molars for reasons of occlusal stability.

Impact of Malocclusion, Tooth Loss and Oral Hygiene Habits on Quality of Life in Orthodontic Patients: A Cross-Sectional Study

We aimed to assess the impact of malocclusion on oral health-related quality of life (OHRQoL) in a sample composed of adolescents, younger adults and adults seeking orthodontic treatment. Participants were consecutively enrolled from January 2019 to March 2020. The oral health impact profile (OHIP-14) was used to measure the OHRQoL. The index of complexity, outcome and need (ICON) was used to assess malocclusion. Sociodemographic, medical, and clinical questionnaires were recorded. Statistical analyses were performed according as a function of sex and age range (15-30 or >30 years old). Linear and logistic regression models were applied to assess the association between OHIP-14 total score, malocclusion, and other relevant confounding variables. In a final sample of 93 participants (60 females and 33 males, aged 15 to 60 years), men reported significantly better OHRQoL (p = 0.005). Participants aged 30 years or older reported significantly worse OHRQoL (p = 0.042). OHIP-14 was significantly correlated with age (ρ = 0.259, p < 0.05) and the number of missing teeth (ρ = 0.369, p < 0.001). Multivariable regression showed OHIP-14 being associated with the number of missing teeth (B = 1.48, SE = 0.57, p < 0.05) and the presence of missing teeth (B = 1.38, SE = 0.65, p < 0.05). Malocclusion showed no association with OHRQoL. Age and the number of missing teeth may be key factors on self-perceived OHRQoL in adult patients seeking orthodontic treatment.

Influence of Fixed Orthodontic Therapy on Pharyngeal Airway Dimensions after Correction of Class-I, -II and -III Skeletal Profiles in Adolescents

The aim was to compare the influence of fixed orthodontic therapy (OT) on the pharyngeal airway space dimensions after correction of class-I, -II and -III skeletal profiles and among untreated adolescent patients. A control group comprising of untreated patients was also included. Demographics and OT-related information was retrieved from patients’ records. Measurements of airway spaces in the nasopharynx, oropharynx and hypopharynx were performed on lateral cephalograms. p-values under 0.05 were considered statistically significant. The results showed no statistically significant differences in the naso-, oro- and hypo-pharyngeal airway spaces among patients with class-I, -II and -III skeletal profiles and individuals in the control group. There were no statistically significant differences when naso-, oro- and hypo-pharyngeal airway spaces were compared among patients with class-I, -II and -III skeletal profiles. In conclusion, in non-extraction cases without maxillary expansion, fixed OT does not affect the naso-, oro- and hypo-pharyngeal airway spaces in patients with skeletal Class-I, -II and -III skeletal profiles. Further studies involving patients undergoing ME and premolar extraction are needed to elucidate the influence of fixed OT on the naso-, oro- and hypo-pharyngeal airway spaces.

Oral health-related quality of life of adolescents assessed with the Malocclusion Impact and Child Perceptions questionnaires

INTRODUCTION

Our study objectives were to evaluate the impact of malocclusion on oral health-related quality of life (OHRQOL) of adolescents aged 11-14 years in Ile-Ife, Nigeria.

METHODS

Two hundred adolescents completed the Child Perceptions Questionnaire: Impact Short Form (CPQ_11-14-ISF:16) and the Malocclusion Impact Questionnaire (MIQ). The Aesthetic Component of the Index of Orthodontic Treatment Need scale was used to determine malocclusion severity. The effect of sex, age, and socioeconomic class on OHRQOL were determined with the Mann-Whitney U test, Kruskal-Wallis H test, correlation tests, and multiple regression analysis using SPSS (version 22.0; IBM, Armonk, NY). Statistical significance was set at P <0.05.

RESULTS

The CPQ_11-14-ISF:16 and MIQ identified the impact of malocclusion on OHRQOL with mean (standard deviation) scores of 12.85 (10.17) and 8.33 (7.50), respectively. Sex, socioeconomic class, and malocclusion severity had no significant effect on OHRQOL (P >0.05); however, OHRQOL differed significantly between the age groups (CPQ_11-14-ISF:16, P = 0.002; MIQ, P = 0.041). Multiple regression analysis showed that age was a significant predictor of OHRQOL determined with CPQ_11-14-ISF:16 (standardized coefficients B score = -0.242, P = 0.001). MIQ demonstrated good criterion validity with CPQ_11-14-ISF:16 (r = 0.59, P <0.001).

CONCLUSIONS

Both measures CPQ_11-14-ISF:16 and MIQ identified the impact of malocclusion on the OHRQOL of adolescents. Sex, socioeconomic class, and malocclusion severity did not affect OHRQOL; however, age was a significant predictor of OHRQOL. Further studies among orthodontic patient populations are desirable.

Clinical and sociodemographic factors associated with oral health knowledge, attitude, and practices of adolescents in Nigeria

Objectives:

The institution of appropriate oral health promotion programs targeted at adolescents in schools in developing countries requires baseline information on their oral health knowledge, attitude, and practices as well as associated factors influencing it, which are unknown. This study assessed clinical and sociodemographic factors associated with oral health knowledge, attitude, and practices of adolescents in Ibadan, Nigeria.

Methods:

Two-thousand and ninety-seven students aged 12–18 years were recruited from 30 randomly selected secondary schools in a cross-sectional study conducted in Ibadan, Nigeria. Data were obtained through a questionnaire on oral health knowledge, attitude, and practices, and sociodemographic characteristics. Oral examination was conducted to assess the clinical oral condition of the adolescents. Data were analyzed with SPSS. The higher the percentage scores, the better the oral health knowledge, attitude, and practices, and overall awareness of oral health.

Results:

The oral health knowledge score ranged from 0% to 60%; mean oral health knowledge score was 15.1% (±6.6%). The oral health attitude score ranged from 0% to 91.3%; mean oral health attitude score was 44.5% (±14.3%). The oral health practices score ranged from 0% to 88.9%, and mean oral health practices score was 42.5% (±13.8%). The mean oral health knowledge, attitude, and practices score was 43.8% (±11.4%). A total of 1537 (73.3%) participants had unhealthy periodontium and 98 (4.7%) had dental caries. Students who were 12–15 years (odds ratio = 1.7, 95% confidence interval = 1.4–2.0, p < 0.001), females (odds ratio = 1.2, 95% confidence interval = 1.0–1.5, p = 0.024), offspring of skilled workers (odds ratio = 1.5, 95% confidence interval = 1.1–2.0, p = 0.010), previously educated about oral health (odds ratio = 1.3, 95% confidence interval = 1.0–1.7, p = 0.023), consulted the dentist (odds ratio = 1.9, 95% confidence interval = 1.2–3.1, p = 0.009), or had unhealthy periodontal condition (odds ratio = 1.2, 95% confidence interval = 1.0–1.5, p = 0.042) were more likely to have higher oral health knowledge, attitude, and practices scores or awareness than others.

Conclusion:

Better knowledge, attitude, and practices score was associated with younger age group, higher occupational class, previous oral health education, dental consultation, and having unhealthy periodontal condition.

Relationships of Dental Caries and Malocclusion with Oral Health-Related Quality of Life in Lithuanian Adolescents Aged 15 to 18 Years: A Cross-Sectional Study

There is a lack of evidence of the moderating effects of caries lesions and malocclusions on oral health-related quality of life (OHRQoL) among older adolescents. This study aimed to evaluate the relationship of dental caries and malocclusion with OHRQoL among Lithuanian adolescents aged 15 to 18 years. A survey in a representative sample of adolescents included a clinical examination to assess dental health status using the DMFT (Decayed, Missing, and Filled Permanent Teeth) index, and malocclusion using the Index of Complexity, Outcome, and Need (ICON). The Child Perceptions Questionnaire (CPQ) was used to evaluate respondents’ OHRQoL. Negative binomial regression was fitted to associate the clinical variables with the CPQ scores. A total of 600 adolescents were examined. The overall mean DMFT score was 2.7. A need for orthodontic treatment was detected among 27.7% of adolescents. Subjects with caries lesions (DMFT > 3) had higher CPQ scores in the domains of functional limitations and social wellbeing (relative risks were 1.35 (95% confidence interval: 1.09–1.67) and 1.30 (1.03–1.64), respectively), while subjects with a need for orthodontic treatment (ICON > 43) had higher CPQ scores in the domains of emotional wellbeing and social wellbeing (relative risks were 1.81 (1.40–2.22), and 1.69 (1.34–2.14), respectively). It was concluded that both dental caries and malocclusion have negative relationships with OHRQoL in adolescents above 15 years, but their effects occur differently in each OHRQoL domain.

Self-Reported Changes in Oral Hygiene Habits among Adolescents Receiving Orthodontic Treatment

The prevalence of malocclusion and a need for orthodontic treatment is high. Orthodontic appliances increase biofilm accumulation by expanding plaque retention sites. The aim of this study was to investigate the self-reported changes in oral hygiene habits among adolescents receiving orthodontic treatment. A cross-sectional study of 291 patients aged 10–17 years (mean (M) = 12.98; standard deviation (SD) = 2.36) was conducted in the Department of Orthodontics, Lithuanian University of Medical Sciences (LSMU) Hospital (Kaunas, Lithuania) during the fall semester (October–January) of the 2017/2018 study year. An anonymous self-administered questionnaire covered background information, experience of orthodontic treatment, oral hygiene habits and the seeking of professional dental care. Statistical data analysis was performed using SPSS version 22. To establish relationships between categorical variables, Chi-squared tests (χ2) were used. A p-value ≤ 0.05 was set to indicate statistically significant difference. The univariate logistic regression analysis evaluated the probability of an event given a certain risk indicator, including odds ratio (OR) and its confidence interval (95% CI). Associations were found between the usage of auxiliary measures (OR = 1.797 (1.118–2.887), p = 0.015), tongue cleaning (OR = 1.712 (1.059–2.767), p = 0.028), mouth rinsing after meals (OR = 1.707 (1.048–2.781), p = 0.032) and experience of orthodontic treatment, respectively. More orthodontic patients underwent professional oral hygiene regularly than non-orthodontic patients (p = 0.024). More patients with fixed orthodontic appliances reported significantly changed oral hygiene habits, while more orthodontic patients with removable appliances did not change their oral hygiene habits.

Family Affluence Based Inequality in Oral Health-Related Quality of Life in a Population of Lithuanian Adolescents

Background: The social inequalities in oral health have had increasing attention in recent years. The present study aimed to explore the impact of family affluence on Oral Health-Related Quality of Life (OHRQoL) among Lithuanian adolescents aged 11–18 years. Methods: The cross-sectional, population-based study included a representative sample of 881 adolescents aged 11–18 years (mean = 15.55; SD = 1.51) randomly selected from 20 schools in Lithuania. The schoolchildren completed questionnaires to evaluate their OHRQoL using a Lithuanian version of the Child Perceptions Questionnaire (CPQ). The adolescents’ family affluence was indirectly assessed by inquiring whether they possessed various modern life items. In dental examination, the severity of malocclusion was predetermined by the Index of Complexity, Outcome, and Need (ICON). The relationship among variables was examined employing the negative binomial regression and the path analysis. Results: The sum score of CPQ as a whole and the sum scores of all four domains were significantly associated with family affluence, indicating higher OHRQoL among adolescents from more affluent families. The severity of malocclusion had a significant association with emotional and social well-being domains of OHRQoL only. Conclusion: This study evidences the family affluence based inequality in OHRQoL among Lithuanian adolescents.

Effect of orthodontic treatment needs on oral health related quality of life among the young population in Delhi NCR-region of North India

Aim:

To assess the effect of orthodontic treatment needs on oral health-related quality of life among the young people of Delhi NCR.

Methods:

The study was conducted on 12–15 years of individuals attending dental clinic/hospital in Delhi NCR region. Data were collected using Index of Orthodontic Treatment Need -Dental Component and oral health impact profile 14 questionnaire. The Chi-square test was used to analyze the qualitative data. SPSS software version 20 was used for statistical analysis.

Results:

Orthodontic treatment needs had an almost similar impact on the daily activities of both males and females. The sense of taste was not significantly affected by the need for orthodontic treatment in either males or females. The proportions of orthodontic patients found to have the painful arch, embarrassment, tension, and self-conscious both in males and females.

Conclusion:

There is a significant correlation of orthodontic treatment needs among oral health-related quality of life.

When the fear of dentist is relevant for more than one's oral health. A structural equation model of dental fear, self-esteem, oral-health-related well-being, and general well-being

PURPOSE

To develop and test a complex model that captures the individuals' general well-being and the specific oral-health-related well-being. We were specifically interested, as a specific research question, if self-esteem, dental fear, and the oral health-related well-being are credible predictors for the general well-being.

PATIENTS AND METHODS

A one-time associative research design measured dental-specific anxiety, self-esteem, oral-health-related specific well-being, and general well-being in 281 participants, 3rd and 6th year dental students (M _Age =22.59 years, SD _Age =3.13; 55% females), which completed a battery of relevant questionnaires: the Dental Fear Survey, the Rosenberg Self-Image Scale, the short form of Oral Health Impact Profile, and the Flourishing Scale. The data were subject to structural equation modeling in order to validate potential pathways of influence hypothesized based on previous evidence from the literature.

RESULTS

We developed and tested a complex structural equations model, in which dental fear influences both the specific oral-health-related well-being and the persons' self-esteem. In turn, self-esteem mediates the influence pathways between dental fear and oral-health-specific well-being, on the one hand, and the overall well-being, on the other hand.

CONCLUSION

Our research contributes directly to strengthening the theoretical basis for future interdisciplinary research, by providing, first, a tested and replicable model that surpasses the simple correlation or prediction, and second, empirical evidence for the significant mutual interdependence between psychological experiences, eg, self-esteem, and the two main aspects of well-being, ie, specific and general. From a practical, clinical viewpoint, our research provides further insights and justification for the importance of educating the patient, on all levels, from the individual clinical practice to community programs and public oral health policies, with respect to the importance of oral health.
