Burden of oral disorders, 1990-2019: estimates from the Global Burden of Disease Study 2019

INTRODUCTION

The aim of this study was to understand the global incidence and disability-adjusted life years (DALY) of oral disorders by age, gender, region, and Sociodemographic Index (SDI) from 1990 to 2019.

MATERIAL AND METHODS

The estimated annual percentage change (EAPC) and 95% confidence intervals (CIs) were used to assess the trends in age-standardized incidence and DALY rates from 1990 to 2019.

RESULTS

The global age-standardized incidence rate (EAPC = 0.01) of oral disorders increased slightly from 1990 to 2019. From 1990 to 2019, the age-standardized DALY rate decreased in high-SDI (EAPC = -0.43) and high-middle-SDI (EAPC = -0.14) regions, but it showed increasing trends in low-SDI (EAPC = 0.22), low-middle-SDI (EAPC = 0.36), and middle-SDI (EAPC = 0.17) regions. The EAPC in the age-standardized DALY rate was negatively correlated with the regional SDI value (ρ = -0.402, p = 0.001). From 1990 to 2019, the region with the largest increase in age-standardized DALY rate was South Asia (EAPC = 0.67), while the country with the greatest increase in age-standardized DALY rate was India (EAPC = 0.82).

CONCLUSIONS

From 1990 to 2019, the global age-standardized incidence rate of oral disorders showed a slight increasing trend. It is necessary to control the increase in DALY and the disease burden associated with oral disorders in low-, low-middle-, and middle-SDI regions, such as South Asia, particularly in India.

Oral medicine practice in Europe and Australia: Identifying practitioner characteristics and their clinical activity

Oral Medicine is a young dental specialty born almost a century ago and deals with orofacial conditions not directly attributable to the most prevalent tooth pathologies such as dental caries or periodontal diseases. Presentations may reflect local disease or orofacial manifestations of more widespread pathology affecting other parts of the body. Due to its recency as a distinct discipline and to heterogeneous global settings, Oral Medicine has not yet achieved a shared scope and definition, as well as a recognized status across the globe. The current report presents survey data gathered from Oral Medicine practitioners in Europe and Australia and aimed to identify practitioner characteristics including demographics, training, clinical and research activity. As expected, Oral Medicine clinical practice commonly deals with conditions such as immune-mediated disorders, potentially malignant disorders, oral mucosal infections and chronic pain disorders, but geographical heterogeneities are observed. The present data, representative of current clinical practice, are valuable in order to understand the evolution of Oral Medicine as a distinct discipline and should be taken into consideration in order to create or update postgraduate training curricula able to meet the needs of future practitioners and the communities they serve.

Burden of oral diseases and noncommunicable diseases: An asia-pacific perspective

Background

At a population level, there are no systematic data to correlate the pattern of prevalence of noncommunicable diseases (NCD) with oral disease burden in South Asian countries. The influence of the age, gender, and geographical distribution on these diseases is not reported. We attempt to provide a population level correlation of occurrence using the Global Burden of Disease approach.

Materials and Methods

Using the data from the Global Burden of Diseases, 2016, the occurrence of oral diseases (dental caries of permanent teeth, edentulism (including severe tooth loss), and periodontal diseases) and various NCDs, based on geographical region, gender and age groups were collected and subjected to correlation statistics. Statistical Package for Social Services (Version 23) was used to analyze the results. P ≤ 0.05 was considered as statistically significant.

Results

Geographical location and age had a significant role in the occurrence of dental diseases. There was a considerable difference in rates of dental diseases and NCD prevalence in the various regions of Asia-Pacific. It was observed that for most of the NCDs, there was a linear significant relationship for edentulism as well as periodontal diseases with high statistical significance.

Discussion

The factors that contribute to the discrepancies, phenomenon, and relationship between the oral diseases and NCDs are discussed. The current state of the importance of oral health, in maintaining overall health is discussed. Methods by which policymakers could bring about a change by utilizing the principles of "Overton window" for mobilizing the support of people are presented.

Study of oral potentially malignant disorders related to various risk factors amongst the patients attending hospitals in Bhopal, India

Background and aims

Oral potentially malignant disorders constitute one of the major oral health problems in India. Few studies have been undertaken on potentially malignant disorders in central India, specifically in Bhopal. Hence the present study was conducted to assess the oral potentially malignant disorders in the patients attending hospitals of Bhopal, India.

Methods

Four hundred subjects diagnosed with oral potentially malignant disorders were included in this study. Detailed information was gathered in a proforma and emphasis was given to the various addictions and clinical findings.

Results

Among the 400 oral potentially malignant disorders diagnosed during the study period, males constituted 78% (n=312) and females 22% (n=88). The mean age of the patients was 33.50 ± 13.24 years for males and 42.60 ± 14.18 years for females. The most commonly affected age group was 21-30 years (37.5%), followed by 31-40 years (25%) and 41-50 years (13%). 87.75% patients were addicted to chewing of betel nut and/or tobacco and/or betel quid, 15.25% were addicted to smoking bidi and/or cigarette, 15.25% were addicted to chewing and smoking, 1% was addicted to chewing and alcohol, and 0.25% was addicted to alcohol and smoking.

Conclusion

In this study, an increase in clinical grading of oral potentially malignant disorders was found with severity and duration of addiction habit. In order to decrease the prevalence of these disorders, it is imperative to continue educational campaigns at national and international level to impart education to the public about the risk factors and early signs and symptoms of the oral potentially malignant disorders.

[Oral manifestations in patients with primary immunodeficiencies]

Characteristic lesions of the oral cavity in primary immunodeficiencies are commonly found in the form of periodontal disease, tooth decay and disorders of the oral mucosa. Humoral immunodeficiencies may cause tooth decay, while severe forms of plaque-induced periodontal disease are common in phagocytic deficiencies. The structural abnormalities of the teeth can occur in immunodeficiencies associated with apoptosis defect. Oral squamous cell carcinoma is a possible complication of immunodeficiencies associated with DNA repair defects. Orv Hetil. 2018; 159(49): 2079-2086.

Qat Chewing and Risk of Potentially Malignant and Malignant Oral Disorders: A Systematic Review

BACKGROUND

Qat (also known as Khat, Kat and Miraa) is a green-leaved plant (Catha edulis). It is a shrub indigenous to Yemen and certain parts of eastern Africa. Chewing the leaves, which have sympathomimetic and euphoric effects, has been documented in many countries and increased with worldwide migration. The effect of long-term chewing Qat on the oral cavity is unknown.

OBJECTIVE

A systematic review was performed to identify any associations between Qat chewing and the occurrence of potentially malignant and malignant oral disorders.

METHODS

Medline and the Web of Science were searched for articles published before May 2014 without limits with regard to publication date and language.

RESULTS

From a total of 890 papers identified, 17 English papers reported potentially malignant or malignant oral disorders and Qat chewing. One additional paper in Arabic language was identified from reviewing the list of references of eligible papers. It was found that exposure to Qat may be associated with potentially malignant and malignant oral disorders, but methodological issues, such as inadequate study design, sample size, selection of study subjects, clinical evaluations of outcome and limited adjustment for confounders, limit the strength of the evidence base in this area.

CONCLUSION

The association between Qat chewing and potentially malignant and malignant oral disorders remains debatable and requires further investigations.
