Dentin hypersensitivity and toothache among patients diagnosed with Molar-Incisor Hypomineralization: A systematic review and meta-analysis

OBJECTIVES

To determine the prevalence of dentin hypersensitivity (DH) and toothache in patients with Molar-Incisor Hypomineralization (MIH); and evaluate whether patients with MIH have greater likelihood of presenting DH/toothache than controls.

DATA

Studies evaluating DH/toothache in patients with MIH were included. Studies focusing on other enamel defects were excluded.

SOURCES

Eight databases, including grey literature, were searched in January 2024.

STUDY SELECTION

The methodological quality of studies was assessed using the Joanna Briggs Institute checklist for Cross-sectional studies. Proportion and association meta-analyses, subgrouped by diagnostic methods, were conducted. The certainty of evidence was assessed using GRADE approach.

RESULTS

Fifteen studies were included in the qualitative analysis and fourteen in the meta-analyses. Two studies fulfilled all items of the methodological quality checklist. The overall prevalence of DH/toothache among patients with MIH was 45 %. Prevalence rates of 30 %, 47 %, and 55 % were estimated based on proxy reports, self-reports, and air stimulation, respectively. The overall prevalence of DH/toothache per tooth was 22 %, ranging from 16 % to 29 % according to the diagnostic method. Patients with MIH demonstrated higher likelihood of presenting proxy reports of DH/toothache compared to those without MIH (OR: 1.51, 95 % CI [1.23-1.85], P < 0.01, I2: 0 %). The certainty of evidence was very low, mainly due to the low methodological quality of included studies and high inconsistency.

CONCLUSIONS

The global prevalence of DH/toothache was 22 %, per tooth, and 45 % per patient. Estimates vary according to diagnostic methods. Patients with MIH showed higher likelihood of presenting proxy reports of DH/toothache than controls.

CLINICAL SIGNIFICANCE

This systematic review contributes valuable information to the dental literature by assessing the prevalence and associated factors of DH/toothache in patients with MIH. The findings can guide future research, inform clinical practices and public policy makers, and ultimately improve the management of oral health of patients with MIH.

Acupuncture in management of acute dental pain - A systematic review and meta-analysis

Acute dental pain is a common issue leading to dental consultation. Besides causal therapy, patients are treated with acupuncture, but efficacy in acute dental pain is still not clarified. We aimed to evaluate results of recent research to estimate the efficacy of acupuncture compared to pain-relieving approaches in treatment of acute dental pain. A systematic review of controlled trials being published between database inception and 2020 were conducted to evaluate the efficacy of acupuncture (alone or as complementary therapy) compared to local anesthesia or conventional analgesic medications in acute dental pain (intraoperatively and postoperatively) and to clarify whether acupuncture reduces the use of postoperative analgesic medications. Of 1672 publications, 23 publications met the inclusion criteria. From these, 11 randomized controlled trials (n = 668) reported on the efficacy of acupuncture on postoperative acute dental pain. Patients, who received acupuncture, showed lower pain scores postoperatively compared to sham acupuncture (Relative Risk -0.77, 95% Confidence interval -1.52 to -0.03). Overall, the results suggest a potential role of acupuncture in improving acute dental pain intraoperatively and postoperatively as well as improving the efficacy of local anesthesia, but the results are limited due to methodological shortcomings emphasizing the necessity for future high-quality research.

Assessing Google Searches for Toothache during COVID-19 Lockdowns

Background

Lockdowns due to the coronavirus disease 2019 (COVID-19) pandemic forced many dental offices to be closed. This study aims to investigate the association between COVID-19 imposed lockdowns and online searches for toothache using Google Trends (GT).

Methods

We investigated GT online searches for the term "toothache" within the past 5 years. The time frame for data gathering was considered as the initiation and end dates of national/regional lockdowns in each country. We used 1-way analysis of variance to identify statistical differences in relative search volumes (RSVs) between 2020 and 2016-2019 for each country.

Results

Overall, 16 countries were included in our analyses. Among all countries, Indonesia (n = 100), Jamaica (n = 56), Philippines (n = 56), Iran (n = 52), and Turkey (47) had the highest RSVs for toothache in the specified period. Compared with the previous 4 years, higher RSVs were seen in the world (as a whole) (2020 RSVs, 94.4; vs 2019 RSVs, 77.8 [ P < 0.001]) and 13 countries (81.3% of the included countries).

Conclusion

Generally, searching for the term "toothache" showed an increase during the COVID-19 lockdowns in 2020 compared with the past 4 years. This can imply the importance of dental care as urgent medical care during public health emergencies such as COVID-19.

The association between poor oral health and risk of breast cancer in the UK Biobank

PURPOSE

Specific oral health conditions may be risk factors for breast cancer. This study aimed to investigate the associations of oral health conditions with breast cancer risk.

METHODS

A total of 234,363 women from the UK Biobank prospective cohort were included in this study. We examined the association of self-reported painful/bleeding gums, loose teeth, mouth ulcers, toothache, and use of dentures with the risk of breast cancer. Hazard ratios (HRs) and 95% confidence intervals (95% CIs) for the associations were calculated with adjustment for multiple confounders.

RESULTS

No associations of self-reported painful/bleeding gums (HR = 1.04, 95% CI 0.98-1.10), loose teeth (HR = 0.92, 95% CI 0.82-1.02), mouth ulcers (HR = 0.99, 95% CI 0.93-1.06), toothache (HR = 1.03, 95% CI 0.92-1.14), or denture use (HR = 0.96, 95% CI 0.91-1.02) with breast cancer risk were found. No statistical heterogeneity was observed in analyses stratified by baseline smoking and menopausal status.

CONCLUSION

We observed no association between self-reported oral health conditions with the risk of breast cancer. Additional research with clinical examinations or oral health biomarkers in diverse populations is warranted.

Dental antibiotics and referrals in general medical practice: Wales 1974-2017

OBJECTIVES

This study aimed to explore trends and predictors for antibiotic prescriptions and referrals for patients seeking dental care at General Medical Practitioners (GMPs) over a 44-year period in Wales, UK.

METHODS

This retrospective observational study analysed data from the nationwide Secure Anonymised Information Linkage Databank of visits to GMPs. Read codes associated with dental diagnoses were extracted from 1974-2017. Data were analysed using descriptive statistics, univariate and multivariable logistic regression.

RESULTS

Over the 44-year period, there were a total of 160,952 antibiotic prescriptions and 2,947 referrals associated with a dental attendance. Antibiotic prescriptions were associated with living in the most deprived (OR 0.91, 95% CI 0.89-0.93) or rural (OR 0.83, 95% CI 0.82-0.84) areas, whereas referrals were associated with living in an urban area (OR 2.16, 95% CI 1.99-2.35) or rural and less deprived area (OR 1.71, 95% CI 1.26-2.33). The number of antibiotic prescriptions decreased over time whereas the number of referrals increased.

CONCLUSIONS

These changes coincide with dental attendance rates at GMPs over the same period and indicate that appointment outcome and repeat patient attendance are linked. Rurality and deprivation may also influence care provided.

CLINICAL SIGNIFICANCE

General medical practices are not the most appropriate place for patients seeking dental care to attend, and efforts should be made to change current practice and policy to support patients to seek care from dental practices. When patients do seek dental care from GMPs they should be encouraged to refer the patient to a dentist rather than prescribe antibiotics as an important element of national antimicrobial stewardship efforts, as well as to discourage repeat attendance.

Can parental pain catastrophizing influence the relationship between dental caries and pain in early childhood?

OBJECTIVE

Knowledge on the parents' catastrophizing of the children's dental pain is lacking. This study aimed to verify whether parental pain catastrophizing influences the relationship between caries and dental pain in early childhood and if the child's age interacts with this relationship.

STUDY DESIGN

A cross-sectional study was carried out with 83 dyads of children and their parents/primary caregivers. The parents answered the Brazilian version of the Pain Catastrophizing Scale-Parents and the Dental Discomfort Questionnaire. The children were examined to measure their caries experience. Correlations, simple mediation, and conditional process analyses were performed.

RESULTS

The research participants were mostly male children (50.6%) with a mean age of 38 months (Q1 33.0, Q3 48.0). Most of the parents were mothers (n = 73; 88.0%) and had catastrophic thoughts (80.7%). Perceived dental pain in the child was positively correlated with the child's caries experience and parental pain catastrophizing. The parents' catastrophizing did not mediate the relationship between the caries experience and the pain intensity (a * b = 0.05; the lowest level of the confidence interval: -0.01; upper level of the confidence interval: 0.14). The child's age did not moderate the direct or indirect effect of the caries experience on the pain intensity of the children.

CONCLUSION

In early childhood, parental catastrophizing of the children's pain and children's age does not influence the direct relationship between children's caries experience reported by the dentist and children's dental pain reported by parents.

Spatiotemporal dynamics of brain function during the natural course in a dental pulp injury model

Purpose

Toothache, a common disorder afflicting most people, shows distinct features at different clinical stages. This study aimed to depict metabolic changes in brain and investigate the potential mechanism involved in the aberrant affective behaviors during the natural process of toothache.

Methods

We investigated the spatiotemporal patterns of brain function during the natural course of toothache in a rat model of dental pulp injury (DPI) by using positron emission tomography (PET).

Results

Glucose metabolism peaked on the 3rd day and gradually decreased in several brain regions after DPI, which was in line with the behavioral and histological results. PET imaging showed that visual pathway was involved in the regulation of toothache. Meanwhile, the process of emotional regulation underlying toothache was mediated by N-methyl-D-aspartic receptor subunit 2B (NR2B) in the caudal anterior cingulate cortex (cACC).

Conclusion

Our results revealed the spatiotemporal neurofunctional patterns during toothache process and preliminarily elucidated the role of NR2B in cACC in the regulation of toothache-related affective behaviors.

Prevalence of toothache and associated factors in children and adolescents: a systematic review and meta-analysis

OBJECTIVES

This systematic review aimed to determine the pooled prevalence of toothache in children and adolescents and to verify its association with sociodemographic characteristics and dental caries experience.

MATERIAL AND METHODS

Six main and three grey literature databases were searched in February 2021. Observational studies that assessed the prevalence of toothache and associated factors were included. The methodological quality of the studies was evaluated following the guidelines by Fowkes and Fulton. Proportion and association meta-analyses were performed in MedCalc and Revman software, respectively. The certainty of the evidence was determined with the GRADE approach.

RESULTS

Seventy-one studies met the inclusion criteria. Thirty-two presented high methodological quality and a low risk of bias. The overall pooled prevalence of toothache in children and adolescents was 36.2% (95%CI: 33.0-39.42; I²: 99.72%; P < 0.001). Females (OR: 1.17; 95%CI: 1.08-1.26; I²: 91%; P < 0.001) and children and adolescents whose caregivers had ≤ 8 years of schooling (OR: 1.42; 95%CI: 1.30-1.56; I²: 77%; P < 0.001) presented the higher chance of reporting toothache. Dental caries experience increased the chance of reporting toothache in 3.49 times (95%CI: 2.70-4.51; I²: 92%; P < 0.001). The certainty of the evidence was very low.

CONCLUSIONS

The overall pooled prevalence of toothache was considered high. Sociodemographic characteristics (sex and caregivers' educational level) and previous dental caries experience were significantly associated with toothache reports.

CLINICAL RELEVANCE

Toothache is still a recurrent issue in many countries. Thus, it is essential to understand its possible associated factors to reduce the occurrence of new episodes.

Impact of untreated dental caries and dental pain on sadness related to oral health of Brazilian children

PURPOSE

Children should feel sad when they believe that a negative outcome is permanent. The sadness that an oral problem might bring tends to contribute to children's loneliness and increase the social stress levels. The aim of this study was to evaluate the impact of untreated dental caries, dental pain, malocclusion, and traumatic dental injury on prevalence of sadness related to oral health among Brazilian children.

METHODS

This cross-sectional study was carried out with 397 children aged 8-10 years randomly selected from public and private schools in Diamantina, Brazil. The Brazilian version of the CPQ_8-10 was applied. Sadness was collected through the question, "In the last month how often did you feel sad because of your teeth or mouth?" and dental pain through the question, "In the last month, how many times have you had pain in your teeth?" One calibrated examiner (Kappa value intra examiner: 0.77-0.91; Kappa value inter examiner: 0.80-1.00) performed the exam for dental caries (DMFT), malocclusion (DAI), and dental trauma (O'Brien). Parents answered questions addressing socioeconomic issues. Descriptive analyses, Chi-square test, and hierarchical Poisson regression models were performed (IC 95%; p < 0.05)."

RESULTS

The prevalence of sadness related to oral health was 30.5% (n = 121). Sadness related to oral health was associated with untreated dental caries (PR: 1.46; 95% CI 1.32-2.46; p = 0.001 ) and dental pain (PR: 2.91; 95% CI 2.00-4.22; p < 0.001). Other clinical variables analyzed (traumatic dental injury and malocclusion) were not significantly associated with sadness related to oral health.

CONCLUSIONS

Children with untreated dental caries and dental pain presented a higher report of sadness related to oral health.

Analysis of tweets on toothache during the COVID-19 pandemic using the CrystalFeel algorithm: a cross-sectional study

Background

Reasons such as the lack of information on the COVID-19 disease, lack of proven treatment for it, uncertainty about the duration of the pandemic, or social isolation affect people’s mental health. This study aimed to analyze the emotional type and intensity in tweets on toothache posted during the COVID-19 pandemic.

Methods

Using the Twitter Search API, we collected tweets in English associated with the keywords “Corona, Toothache” “Corona, Tooth, Pain” “Corona, Dental Pain” “Covid-19, Toothache” “Covid-19, Tooth, Pain” and “Covid-19, Dental Pain” posted between March 11, 2020 and June 30, 2020 all around the world. After the relevant inclusion and exclusion criteria were applied, 426 posts were selected and analyzed using the CrystalFeel algorithm, a sensitivity analytical technology with proven accuracy. The chi-square test (SPSS v23, IBM) was used to compare emotions and emotional intensities according to the words used.

Results

It was determined that 80.3% of the participants experienced fear and 61.7% had a negative emotional intensity. There was no statistically significant difference between the distributions of emotions according to the words without time distinction (p = 0.136). There was a statistically significant difference between the distributions of emotional intensity according to the words without time distinction (p = 0.006). The keyword “Corona, Toothache” was used the most frequently by 30.8% of the participants.

Conclusions

This study is the first to analyze the emotional reactions of individuals who experienced toothaches during the COVID-19 pandemic using the CrystalFeel algorithm. Monitoring the social media posts of individuals experiencing toothache during the pandemic will help reduce fear and anger emotions and design public information messages that are compatible with the target group’s needs.

Association of COVID-19-imposed lockdown and online searches for toothache in Iran

Background

Novel coronavirus disease-2019 (COVID-19) has impacted populations in many ways worldwide, including access to oral health services. This study aims to assess the association between lockdown due to COVID-19 and online searches for toothache in Iran using Google Trends (GT).

Methods

We investigated GT online searches for toothache within the past five years. The time frame for data gathering was considered as the initiation and end dates of the national lockdown in Iran. We performed one-way ANOVA statistical test to compare relative search volumes (RSVs) between the year 2020 and 2016–2019 for the whole country. Then we investigated the possible association of RSVs in provinces with dentists’ density, prevalence of current daily smokers, Human Development Index (HDI), Internet access, and fluoride concentration in water using linear regression.

Results

When comparing 2020 with the previous four years, there was a rise of 2020 RSVs versus all previous years combined and each year (P < 0.001 for all of them). In the linear model for the year 2020, HDI (B = − 3.29, 95% CI: (− 5.80, − 0.78), P = 0.012) had a strong negative relationship with provincial RSVs. HDI mostly had strong positive relationship with provincial RSVs in prior years. Fluoride concentration (B = − 0.13, 95% CI: (− 0.24, − 0.03), P = 0.017) and dentists’ density (B = − 0.04, 95% CI: (− 0.25, 0.17), P = 0.669) were also negatively associated with RSVs in 2020. These associations were mostly negative in the previous years as well. Internet access (B = 0.36, 95% CI: (− 0.38, 1.09), P = 0.325) and prevalence of daily smokers (B = 0.33, 95% CI: (0.13, 0.53), P = 0.002) were positively associated with RSVs.

Conclusion

The RSVs for toothache in 2020 have increased due to COVID-19-imposed lockdown compared with the same period in the past four years. This increase was related to socioeconomic factors.

Dental Pain in Homeless Adults in Porto Alegre, Brazil

Objective

To evaluate the association of dental pain with time living on the street in a sample of homeless people in the city of Porto Alegre, Brazil.

Methods

A cross-sectional study was carried out with homeless people who accessed social services in 2017. A questionnaire was administered covering socioeconomic variables and including questions about general health, use of tobacco/alcohol/drugs, use of dental services and history of dental pain. The decayed, missing, and filled teeth (DMFT) index was calculated in an oral examination. The association between socioeconomic characteristics, health status, time of homelessness and dental pain was evaluated using chi-square, t-, and Mann-Whitney tests.

Results

A total sample of 214 homeless people was surveyed. Most were male (76.2%), had a low level of education (67.6%) and experienced many episodes of dental pain during life (91.0%). The last episode of pain was moderate or intense (79.7%) and do-it-yourself measures for pain relief were preferred (62.3%). Individuals who were homeless for longer than 1 year had more dental pain in the past (P < 0.001), more frequency of a recent episode of dental pain (P = 0.03), and sought a dentist or healthcare service to relieve pain less frequently (P = 0.03).

Conclusions

Dental pain is frequent in the context of homelessness and does not necessarily result in seeking dental services, even where there is universal oral health care.

Global and regional estimates of dental pain among children and adolescents-systematic review and meta-analysis

AIM

We aimed to evaluate the pooled prevalence of dental pain amongst children and adolescents.

METHODS

Studies conducted in children and adolescents up to18 years of age and where prevalence of dental is reported or calculated were included. Search was performed in four major databases from inception to June 1st, 2019. Prevalence estimate at the maximal recall for the dental pain for the individual study was used to calculate the overall pooled estimate.

RESULTS

The prevalence of dental pain ranged from 1.33 to 87.8% in the included publications for quantitative synthesis (n = 97). More than half of the publications reported the lifetime prevalence of dental pain (n = 51) while few studies reported the current prevalence of dental pain (n = 3) and only one study evaluated the dental pain in the past one week. Heterogeneity was high among the included publications (Q = 49,063.12; P < 0.001; df = 96 and I² = 99.8; P < 0.001). Overall pooled prevalence of dental pain was 32.7 (CI = 29.6-35.9). No difference was seen with respect to the trends in prevalence of dental pain (Coefficient: 0.005; 95% CI - 0.001-0.011; P-value: 0.101).

CONCLUSION

Two out of ten children below five years, four out of ten children between 6 and 12 years and three out of ten adolescents between 13 and 18 years would have experienced pain in the past. Overall, three out of ten children or adolescents might have experienced dental pain in the past. There was no difference in the pain prevalence between male and females. Studies from Africa reported highest pooled prevalence (50.1%) with least being from Australia (20.7%). Studies from India (40.4%), China (41.3%) and Iran (42.6%) reported high pooled prevalence estimates of dental pain.

Adhesive restoration of molars affected by molar incisor hypomineralization: a randomized clinical trial

OBJECTIVE

This randomized clinical trial evaluated the survival of direct restorations on first permanent molars (FPMs) with molar incisor hypomineralization (MIH) and its impact on self-reported dental pain and dental anxiety.

MATERIAL AND METHOD

FPMs with MIH of 35 patients aged 7 to 16 years were included. The FPMs were randomized into the following two groups: total-etch (TE-37% phosphoric acid etching) and self-etch (SE-no prior etching). The FPMs were restored with universal adhesive and bulk-fill resin composites. The restoration survival was evaluated according to USPHS criteria modified by a blinded examiner. Dental anxiety (Venham picture test) and dental pain (Faces pain scale-revised) were evaluated before treatment and at 1, 6, and 12 months post-treatment. Survival rates were analyzed by the Kaplan-Meier method and the log-rank test. Nonparametric tests compared pain and anxiety in the follow-up periods.

RESULTS

A total of 64 FPMs were restored (TE = 33; SE = 31). Survival rates were 96.9% (TE) and 96.7% (SE) after 1 month, 90.5% (TE) and 80.6% (SE) after 6 months, and 80.8% (TE) and 62.3% (SE) after 12 months (p > 0.05). Self-reported dental pain and anxiety level decreased after treatment in both groups (p < 0.05). Self-reported pain decreased after 1 month in SE, but it occurred at 6 months in TE.

CONCLUSION

Both restorative protocols presented similar longevity, decreasing self-reported pain and anxiety levels.

CLINICAL RELEVANCE

A universal adhesive could be appropriate for restoration of MIH-affected teeth, and the survival of restorations could be higher in the total-etch technique, reducing dental pain and anxiety.

Determinants of parental report of dental pain and discomfort in preschool children-The Dental Discomfort Questionnaire

BACKGROUND

Pain is a major consequence of caries, which negatively impacts the quality of life of children and their families.

AIM

To analyse the parental report of dental pain and discomfort in preschool children, and to identify clinical and sociodemographic factors associated.

DESIGN

This cross-sectional study involved 375 four- and five-year-old preschoolers enrolled in the city of Campo Magro public school system, along with their parents and caregivers. Parents/caregivers answered the Brazilian version of the Dental Discomfort Questionnaire (DDQ-B) and a sociodemographic questionnaire. Two examiners (kappa > 0.79) performed clinical examinations using dmf-t and pufa index. The associations were statistically analysed by univariate and multiple Poisson regression with robust variance (α = 0.05).

RESULTS

The prevalence of dental pain and discomfort was 70.3% (66%-75% 95% CI). Children from non-nuclear families (PR_a 1.33; 95% CI: 1.01-1.76) and whose parents presented a lower level of education (PR_a 2.43; 95% CI 1.66-3.55) presented a higher prevalence of dental pain or discomfort. Considering the clinical determinants, after adjusting, only the presence of clinical consequences of untreated dental caries (pufa ≥ 1) (PR_a 1.37; 95% CI 1.02-1.84) was significantly associated with higher dental pain or discomfort.

CONCLUSIONS

Dental pain and discomfort were associated with socioeconomic factors and with the presence of clinical consequences of untreated dental caries.

Is there a healthy migrant effect in relation to oral health among adults in England?

OBJECTIVE

The aim of the study was to assess the healthy migrant effect in relation to oral health among adults in England.

STUDY DESIGN

This is a secondary data analysis of a nationally representative survey.

METHODS

Data from 13,373 adults of Irish, black Caribbean, Indian, Pakistani, Bangladeshi and Chinese ethnicity, who participated in the Health Survey for England, were analysed. The proportions of edentate and dentate adults with toothache in the last 6 months in first- and second-generation migrants within each ethnic group were compared with those in the white British (reference group) ethnic group in logistic regression models after adjusting for demographic factors and socio-economic position. Among first-generation migrants, the associations of age at arrival and length of residence with each oral health outcome were assessed in logistic regression models after adjusting for sociodemographic factors.

RESULTS

Compared with white British migrants, first-generation black Caribbean (odds ratio [OR]: 1.42) and second-generation Pakistani (OR: 3.16) migrants had higher odds of being edentulous, whereas first-generation Indian (OR: 0.62), Pakistani (OR: 0.62), Bangladeshi (OR: 0.41) and Chinese (OR: 0.49) migrants had lower odds. Among dentate adults, second-generation Irish (OR: 1.51) migrants, first- and second-generation black Caribbean (OR: 1.61 and 1.54, respectively) migrants, first-generation Indian (OR: 1.24) migrants and second-generation Pakistani (OR: 1.34) migrants had higher odds of having toothache in the past 6 months, whereas second-generation Bangladeshi (OR: 0.51) migrants had lower odds than white British. Age at arrival and length of residence were positively associated with being edentulous among first-generation black Caribbean, Pakistani and Bangladeshi migrants.

CONCLUSION

Evidence on the healthy migrant effect was mixed, with more consistent findings seen for edentulousness among Asian groups. Black Caribbean migrants were generally the ethnic group with the worst oral health when compared with white British.

Levels of toothache-related interests of Google and YouTube users from developed and developing countries over time

Background

The preferences of Web users can be influenced by distinct factors of populations. Hence, hypothetically, source-based patterns of health-related Web searches might differ between individuals from developed and developing countries, due to their distinct educational, social, economic, political, cultural, and psychosocial backgrounds. In this context, this study aimed to determine the trends of toothache-related searches performed on Google Search and YouTube, regarding differences between developed and developing countries.

Methods

This retrospective longitudinal study analyzed computational metadata on toothache-related interests of Internet users. Google Trends was accessed to obtain the monthly variation of relative search volume (RSV) of the topic “Toothache-Disease” on Google (G) and YouTube (YT) through 2008–2017. Autocorrelation and partial autocorrelation plots, ARIMA models, Kruskal–Wallis, Dunn’s and T tests were performed for evaluating trends, 12-month forecasts and the differences of annual ratios of YT/G searches between developed and developing countries, respectively (P < 0.05).

Results

Uptrends of RSVs were observed in both country groups over time, although 12-month forecasts tended to plateau.The volumes of searches were higher in developed countries in comparison to developing ones; however, this difference was not observed regarding Google searches performed between 2016 and 2017. Independently of country groups, the ratios YT/G remained relatively constant throughout the period, indicating a greater interest in toothache-related information available on Google.

Conclusion

In conclusion, toothache-related searches from Google and YouTube increased during the last decade. The preferences of Web users seemed to be influenced by the differences between developed and developing countries, such as the availability and penetration of the Internet, and education levels.

Socioeconomic inequalities in adult oral health across different ethnic groups in England

BACKGROUND

Ethnic inequalities in oral health among British adults remain largely unexplored. This study explored the role of socioeconomic position (SEP) in explaining ethnic inequalities in oral health; and the consistency of socioeconomic inequalities in oral health across ethnic groups.

METHODS

Data from 45,599 adults, aged 16 years and over, who participated in the Health Survey for England were pooled across 5 years. The seven ethnic groups included were White British, Irish, Black Caribbean, Indian, Pakistani, Bangladeshi and Chinese. Edentulousness and toothache were the outcome measures. A composite measure of SEP was developed based on education, social class, income and economic activity using confirmatory factor analysis. Ethnic inequalities in oral health were assessed in logistic regression adjusting for sex, age, survey year and SEP.

RESULTS

Indian (OR: 0.55, 95%CI: 0.40-0.76), Pakistani (0.56, 0.38-0.83), Bangladeshi (0.35, 0.23-0.52) and Chinese (0.41, 0.25-0.66) were less likely to be edentulous than White British after controlling for SEP. Irish (1.22, 1.06-1.39) and Caribbean (1.37, 1.19-1.58) were more likely and Bangladeshi (0.83, 0.69-0.99) were less likely to have toothache than White British after controlling for SEP. Socioeconomic inequalities in edentulousness were consistently found across almost all ethnic groups while socioeconomic inequalities in toothache were found among White British and Irish only.

CONCLUSION

This study shows that the role of SEP in explaining ethnic inequalities in oral health depended on the outcome being investigated. Socioeconomic inequalities in oral health among minority ethnic groups did not consistently reflect the patterns found in White British.

The pain colour of children with toothache in Turkish population

Background

Toothache is a common consequence of untreated caries, predisposed by poor oral hygiene and high caries risk. Most children expressed their pain through their parents or carers. The aim of this study was to determine the colour of pain presence and absence.

Methods

Patients aged between 4 and 14 and referred to a dentist for the first time due to toothache had a short-term pain of 1 month caused by deep cavities. The children chose paintings from the box of 24 standard colours (Crayola, Spain) and the circles were painted. Pain was rated by children on the Visual Analoge Scale. Normality and variance were tested using the one-sample Kolmogorov-Smirnov test. Associations were performed by using the Pearson correlation coefficient. Analyses were completed by using the Statistical Package for Social Sciences (SPSS Inc., Chicago, IL) version 20.0 program.

Results

A total of 147 patients including 78 girls (53.1%) and 69 boys (46.9%) were included in the study. The principal component analysis showed that red has the highest factor loading in children with pain, whereas yellow was the other highest one in children without pain.

Conclusion

The presence of pain was mainly associated with red, and the absence of pain was associated with yellow in Turkish population. Description of pain with colour can be useful tool to recognize the children and to improve dentist-patient or dentist-parents communication.

Pain measurement in oral and maxillofacial surgery

Regardless of whether it is acute or chronic, the assessment of pain should be simple and practical. Since the intensity of pain is thought to be one of the primary factors that determine its effect on a human's overall function and sense, there are many scales to assess pain. The aim of the current article was to review pain intensity scales that are commonly used in dental and oral and maxillofacial surgery (OMFS). Previous studies demonstrated that multidimensional scales, such as the McGill Pain Questionnaire, Short form of the McGill Pain Questionnaire, and Wisconsin Brief Pain Questionnaire were suitable for assessing chronic pain, while unidimensional scales, like the Visual Analogue Scales (VAS), Verbal descriptor scale, Verbal rating scale, Numerical rating Scale, Faces Pain Scale, Wong-Baker Faces Pain Rating Scale (WBS), and Full Cup Test, were used to evaluate acute pain. The WBS is widely used to assess pain in children and elderly because other scales are often difficult to understand, which could consequently lead to an overestimation of the pain intensity. In dental or OMFS research, the use of the VAS is more common because it is more reliable, valid, sensitive, and appropriate. However, some researchers use NRS to evaluate OMFS pain in adults because this scale is easier to use than VAS and yields relatively similar pain scores. This review only assessed pain scales used for post-operative OMFS or dental pain.

Tweeting about pain: comparing self-reported toothache experiences with those of backaches, earaches and headaches

BACKGROUND

The authors conducted a study of tweets posted on Twitter to compare self-reported toothache experiences with those of backache, earache and headache in regard to pain intensity, action taken, perceived cause and effect of pain.

METHODS

From a total of 508,591 relevant tweets collected on seven nonconsecutive days, the authors randomly selected 1,204 tweets (301 per pain type) and conducted content analyses of each tweet.

RESULTS

Toothaches were described as having higher pain intensity than were earaches or headaches but pain intensity comparable with that of backaches. Despite people who experience toothache being more likely to seek health care than those experiencing backaches (odds ratio [OR], 3.91; 95 percent confidence interval [CI], 1.57-9.71) or headaches (OR, 6.11; 95 percent CI, 2.16-17.25), only one in 10 people with toothaches mentioned seeking health care for their pain. People with toothaches were less likely to report an effect on daily functioning compared with those with backaches (OR, 0.13; 95 percent CI, 0.03-0.56) or earaches (OR, 0.19; 95 percent CI, 0.05-0.77).

CONCLUSIONS

Using unsolicited self-reported data from Twitter, the authors found similarities and differences in the experiences of people with toothaches compared with those of people with other common pains. These findings offer insights into understanding dental pain and dental care utilization.

PRACTICAL IMPLICATIONS

The use of social media, such as Twitter, to discuss health issues provides opportunities for dental professionals to better understand dental care experiences from the patients' perspective. Furthermore, social media such as Twitter offer providers the opportunity to share information with the public and to facilitate provider-patient communication.

Behaviors and Management of the Dental Problems by the Residents of Madinah, Saudi Arabia

INTRODUCTION

Dental problems are commonly encountered in our lives. Some of the common problems are toothache, bleeding gums and halitosis.

OBJECTIVES

How the dental problems were handled, and reasons of not seeking dental treatment by the patients.

MATERIALS AND METHODS

This was an observational analytical cross-sectional study on adult's age above 14 years from Madinah.

RESULTS

A total of 400 adults were included; 208 (52%) were males and 192 (48%) were females. Resident encountered toothache surprisingly only 49% sought dental treatment, while (41%) settled for taking medications. Among bleeding gum patients most of them (45%) went to the dentist, while (41%) settled for using the home care. And dealing with halitosis only (17%) went to the dentist. The most common reasons for not seeking dental treatment were fear and long appointments. And mostly they had fear because of dental drill and dental needle.

CONCLUSION

The most common problems for seeking treatment were toothache followed by bleeding gums and the least was halitosis. Number of people who sought treatment was still a low number. The most common reason that stopped patients from going to the dentist was fear and long appointments. There should be increase of dental clinics and patients should be given dental education.

Urinary heavy metals, phthalates, phenols, thiocyanate, parabens, pesticides, polyaromatic hydrocarbons but not arsenic or polyfluorinated compounds are associated with adult oral health: USA NHANES, 2011-2012

Links between environmental chemicals and human health have emerged over the last few decades, but the effects on oral health have been less studied. Therefore, it was aimed to study the relationships of different sets of urinary chemical concentrations and adult oral health conditions in a national and population-based setting. Data was retrieved from the United States National Health and Nutrition Examination Surveys, 2011-2012 including demographics, self-reported oral health conditions and urinary environmental chemical concentrations (one third representative sample of the study population). Chi-square test, t test, and survey-weighted logistic and multi-nominal regression modeling were performed. Of 4566 American adults aged 30-80, 541 adults (11.9 %) reported poor teeth health while 1020 adults (22.4 %) reported fair teeth. Eight hundred fifty-five people (19.1 %) claimed to have gum disease, presented with higher levels of urinary cadmium, cobalt and polyaromatic hydrocarbons. Six hundred three adults (13.3 %) had bone loss around the mouth, presented with higher levels of cadmium, nitrate, thiocyanate, propyl paraben and polyaromatic hydrocarbons. Eight hundred forty-five adults (18.5 %) had tooth loose not due to injury, presented with higher level of cadmium, thiocyanate and polyaromatic hydrocarbons. Eight hundred forty-five adults (18.5 %) with higher levels of lead, uranium, polyaromatic hydrocarbons but lower level of triclosan noticed their teeth did not look right. Three hundred fifty-one adults (7.7 %) often had aching in the mouth and 650 (14.3 %) had it occasionally, presented with higher levels of phthalates, pesticides and polyaromatic hydrocarbons. Benzophenone-3 and triclosan elicited protective effects. Regulation of environmental chemicals in prevention of adult oral health might need to be considered in future health and environmental policies.

Dental pain and self-care: a cross-sectional study of people with low socio-economic status residing in rural India

CONTEXT

Self-care is one of the ways in which people without access to professional care can actively engage in managing their oral health problems.

AIM

To find out the prevalence of dental pain and the type of self-care remedies utilised for pain relief by people with low socio-economic status residing in Kollipara mandal, Guntur district, Andhra Pradesh.

SETTINGS AND DESIGN

This was a cross-sectional population-based study.

METHODS AND MATERIAL

A multistage simple random-sampling technique was adopted to obtain an appropriate sample. A questionnaire, which consisted of sections on socio-economic and demographic variables, dental pain, pain characteristics and self-care remedies utilised to combat dental pain, was used to collect data. Statistical analysis used the chi-square test and descriptive statistics.

RESULTS

The survey covered a total population of 630 individuals. The mean age of the population was 32.8±16.7 years. Among the total study subjects, 44.1% were male and 55.9% were female. The prevalence of dental pain reported during the preceding 6 months was 28.3%. Subjects who experienced dental pain reported the home remedies and self-care methods that they utilised to get relief from the pain. They more frequently reported using over-the-counter medication (49.6%) for pain relief.

CONCLUSIONS

This study provides an insight into the type and usage of self-care in relief of dental pain. Pain sufferers used a variety of self-care methods to deal with their problems.

Rhinolith mimicking a toothache

•

Rhinoliths are uncommon clinical entities.

•

Toothache is not known to be the typical presenting symptom, and has yet to be reported.

•

The pathogenesis of rhinolith remains unclear.

•

Symptomatic lesions will require surgical removal.

•

Although rare, rhinolith should be included as a differential diagnosis of atypical odontogenic pain in the absence of obvious clinical dental pathology.

Introduction

A rhinolith is a calcified mass formed as a result of solidification of mucous foreign objects and gradual accretion of mineral salts. Toothache is not known to be the typical presenting symptom, and to our knowledge, has yet to be reported.

Case report

A 42-year old female referred by her general dental practitioner with a four month history of constant pain of the unrestored upper right central incisor tooth. Incidentally, she also gave a one year history of right-sided sinonasal congestion and intermittent blood stained rhinorrhea.

Discussion

Rhinoliths are uncommon and rarely encountered in clinical practice. This is due to the fact that they remain asymptomatic, and undetected for many years. They may present as incidental radio-opaque lesions in the nasal maxillary antrum on routine dental panoramic radiographs.

Conclusion

Rhinolith should be part of the differential diagnosis of atypical anterior maxillary dental pain in the absence of obvious clinical dental pathology.

[Toothache: At what point has a pontocerebellar angle tumor to be evoked?]

INTRODUCTION

Dental pain may have another origin than teeth. It may be caused by myofascial, neurovascular, cardiac, neurological, sinusal or psychological factors. We will discuss 2 rare cases of patients who presented with a cerebellopontine tumor, who initially manifested with symptoms of dental pain.

OBSERVATION

The first patient, male, 44 years of age presented to his dentist with toothache (47), which led to its extraction. Five months later, a second painful episode, more characteristic, revealed the presence of a vestibular schwannoma, which was successfully treated and led to the disappearance of the pain. The second case, a 43-year-old female presented to her dentist with toothache (46), which lead the dentist perform a root filling. Two years later, with a 3rd episode of dental pain, more relevant of a trigeminal neuralgia, a epidermoid cyst of the right cerebellopontine angle was identified and successfully treated leading to the disappearance of the pain.

DISCUSSION

Cerebellopontine tumors of this type may lead, in exceptional cases to symptoms of dental pain. Therefore, in face of atypical tooth or facial pain, both a detailed medical history and a detailed examination are necessary, in order to investigate any neurological signs and symptoms, before undertaking any non-essential dental treatment, which may be detrimental for the patients.

Association between unmet dental needs and school absenteeism because of illness or injury among U.S. school children and adolescents aged 6-17 years, 2011-2012

BACKGROUND

We assessed the prevalence of dental disease among U.S. children and adolescents aged 6-17 years, as well as the impact of unmet dental needs on school absenteeism because of illness/injury within the past 12 months.

METHODS

Data were from the 2011/2012 National Survey of Children's Health (n=65,680). Unmet dental need was defined as lack of access to appropriate and timely preventive or therapeutic dental healthcare when needed within the past 12 months. The impact of unmet dental needs on school absenteeism was measured using a multivariate generalized linear model with Poisson probability distribution (p<0.05).

RESULTS

Within the past 12 months, 21.8% (10.8 million) of all U.S. children and adolescents aged 6-17 years had "a toothache, decayed teeth, or unfilled cavities." Of all U.S. children and adolescents aged 6-17 years, 15.8% (7.8 million) reported any unmet dental need (i.e., preventive and/or therapeutic dental need) within the past 12 months. The mean number of days of school absence because of illness/injury was higher among students with an unmet therapeutic dental need in the presence of a dental condition compared to those reporting no unmet dental need (β=0.25; p<0.001).

CONCLUSIONS

Enhanced and sustained efforts are needed to increase access to dental services among underserved U.S. children and adolescents.

Toothache and self-medication practices: a study of patients attending a niger delta tertiary hospital in Nigeria

Background:

There is evidence that self-medication practices among dental patients with toothache are common, and despite the adverse clinical consequences, there is a paucity of literature on it, and only few programs are available for its control.

Aim:

The aim was to assess the self-medication practices among adult dental patients suffering from toothache.

Subjects and Methods:

An instrument adapted from modified form of 117-item self-report questionnaire based on world Health Organization guidelines for students’ substance use survey and open-ended questionnaire was administered to adult patients attending the Dental and Maxillofacial Surgery Clinic of this Health Institution for a period of 6 months.

Results:

The results show that 80.6% (287/356) subjects indulged in self-medication practices. Majority of the patients 42.9% (123/287) were in the 2-4^th decades of life, whereas the male: female ratio was 1.3:1. The most commonly abused medications/substance was analgesics/non-steroidal anti-inflammatory drug (243/287; 24.5%), antibiotics (233/287; 23.5%), “touch and go” (187/287; 18.8%). The practice of self-medication cut across all social strata, P < 0.01 (significant) and only 3.8% (11/287) subjects admitted knowledge of the dosage and side-effects of the used medications/substances. The toothache not being serious initially (112/287; 22.5%) and time constraints to attend dental clinic (93/287; 18.7%) were the major reasons for self-medication.

Conclusion:

This study suggests that the practice of self-medication is common among adult dental patients with toothache in Nigeria. This should be reduced to the barest minimum by dental health education, upgrading of dental health facilities, and enforcement of drug control mechanisms.

Ginsenosides Have a Suppressive Effect on c-Fos Expression in Brain and Reduce Cardiovascular Responses Increased by Noxious Stimulation to the Rat Tooth

The purpose of this study is to investigate the antinociceptive effects of ginsenosides on toothache. c-Fos immunoreactive (IR) neurons were examined after noxious intrapulpal stimulation (NS) by intrapulpal injection of 2 M KCl into upper and lower incisor pulps exposed by bone cutter in Sprague Dawley rats. The number of Fos-IR neurons was increased in the trigeminal subnucleus caudalis (Vc) and the transitional region between Vc and subnucleus interpolaris (Vi) by NS to tooth. The intradental NS raised arterial blood pressure (BP) and heart rate (HR). The number of Fos-IR neurons was also enhanced in thalamic ventral posteromedial nucleus (VPMN) and centrolateral nucleus (CLN) by NS to tooth. The intradental NS increased the number of Fos-IR neurons in the nucleus tractus solitarius (NTS) and rostral ventrolateral medulla (RVLM), hypothalamic supraoptic nucleus (SON) and paraventricular nucleus (PVN), central cardiovascular regulation centers. Ginsenosides reduced the number of c-Fos-IR increased by NS to tooth in the trigeminal Vc and thalamic VPMN and CLN. Naloxone, an opioid antagonist, did not block the effect of ginsenoside on the number of Fos-IR neurons enhanced by NS to tooth in the trigeminal Vc and thalamic VPMN and CLN. Ginsenosides ameliorated arterial BP and HR raised by NS to tooth and reduced the number of Fos-IR neurons increased by NS to tooth in the NTS, RVLM, hypothalamic SON, and PVN. These results suggest that ginsenosides have an antinociceptive effect on toothache through non-opioid system and attenuates BP and HR increased by NS to tooth.

Prevalence of toothache and associated factors: a population-based study in southeast iran

INTRODUCTION

This study was carried out to estimate toothache prevalence among adult residents in Kerman.

MATERIALS AND METHODS

This cross-sectional, population-based study was conducted among individuals aged over 18 years (n=1800). The relevant data on the prevalence of toothache and associated factors were collected by interviewing the individuals in their homes and filling out a questionnaire designed by the examiners. Prevalence of toothache and associated factors that patients recalled previous to their interview were analyzed by chi-square test and multivariate logistic regression analysis.

RESULTS

Nine hundred ninety-one individuals (55.1%) reported toothache during the 6 months before the interview. The participants who flossed daily, had regular dental visits, and had higher education showed a significantly lower prevalence of toothache (P<0.05), whereas regular tooth brushing and economic level of residency had no significant effect on the prevalence of toothache. Individuals between the ages of 26 and 45 [odds ratio (OR)=2.0], with a family size of more than 4 (OR=1.5), not using dental floss (OR=1.5), or having a mental or psychological illness (OR=1.5) were more likely to have a history of toothache.

CONCLUSION

High prevalence of toothache (more than half) among residents of Kerman shows a serious and major public health problem. Toothache prevalence in middle aged adults, lower education, bigger family size, lower dental hygiene habit and/or those having mental or psychological illness were more common in the city of Kerman.

Ludwig'S angina following self application of an acidic chemical

Ludwig's angina is a potentially life threatening diffuse cellulitis usually resulting from odontogenic infection. We report a case of Ludwig's angina resulting from self administration of an acidic chemical to treat toothache.
