Bacterial infection in intra-oral cavities can develop into a pathogenic biofilm, which then induces inflammatory processes. One of the necessary dental treatment steps is the disinfection of the infected area, whether it is in the root canal, or in the periodontal, periapical, or peri-implant regions. The objective of this review was to assess the actual situation and trends in the treatments for three of the most important areas of dental health: peri-implantitis, periodontitis, and endodontics. Methods: Results from clinical studies, reports from dental associations, national health insurance records, and market reports were used to quantify the number of treatment needs. For peri-implantitis, the number of inserted implants and the prevalence of peri-implantitis build the basis for the computation. For periodontitis and root canal treatments (RCTs), health insurance figures, and reports on dental instrument orders are the data sources for the estimations. Results: The data show that the number of performed periodontitis and RCTs increase linearly over the year, mainly driven by demographic changes, i.e., increase in size and age of populations. The computed values show that the treatment need for peri-implantitis follows an exponential growth and may surpass that of periodontitis by 2023 in Europe and in the USA. Conclusion: Where dental implantology is growing, the rapid development of peri-implant diseases will burden the health systems. This should be addressed at different levels. At the practitioners’ level, this includes continuous training of staff and (re)investment in adequate material and infrastructures. At the governmental level, it includes policy development and reimbursement strategies as well as information dissemination in health insurance and dental associations. Last, but not least, R&D efforts in the public and private sectors should be implemented/boosted.","PeriodicalId":41793,"journal":{"name":"Journal of Oral Health and Oral Epidemiology","volume":null,"pages":null},"PeriodicalIF":0.4,"publicationDate":"2023-03-29","publicationTypes":"Journal Article","fieldsOfStudy":null,"isOpenAccess":false,"openAccessPdf":"","citationCount":null,"resultStr":null,"platform":"Semanticscholar","paperid":"49268265","PeriodicalName":null,"FirstCategoryId":null,"ListUrlMain":null,"RegionNum":0,"RegionCategory":"","ArticlePicture":[],"TitleCN":null,"AbstractTextCN":null,"PMCID":"","EPubDate":null,"PubModel":null,"JCR":null,"JCRName":null,"Score":null,"Total":0}

In this study, it was intended to explore OHRQoL and its pertinent factors in pre-school children. Methods: This cross-sectional study was directed on 352 mothers with children (aged 3–5 years) based on stratified random sampling in health centers in Tabriz, Iran. Data were collected using a self-report questionnaire completed by the caregiver, which includes socio-demographic data, OHRQoL (13 items), caregiver-reported children’s oral health status, and tooth brushing. The one-way ANOVA, independent samples t test, and linear regression were applied to define the predicators of OHRQoL using SPSS 16 at 95% significance level. Results: Mothers’ mean age was 31.5 (SD=4.9). It was 4.1 (SD=0.82) for children. According to the results, the majority of the mothers (88%) were homemakers and 25% had higher education. The mean (SD) of OHRQoL was 18.8 (7.9) out of 65. The items most related to OHRQoL were feeling guilty (25%), dental pain (35%), and difficulty eating (14.8%). According to the results of multiple regression, OHRQoL had significant relationship with economic status (P=0.046), caregiver-reported children’s oral health status (P=0.0001), children’s frequency of tooth-brushing (P=0.001), and their age (P=0.0001). In total, these factors described 0.22% of the variance in children’s OHRQoL. OHRQoL did not have a statistically significant relationship with mothers’ education level or children’s gender. Conclusion: According to the findings, the key predictor of OHRQoL was children’s oral health status, tooth brushing, and age. Effective educational interventions could be designed based on these predictors to improve the OHRQoL of children.","PeriodicalId":41793,"journal":{"name":"Journal of Oral Health and Oral Epidemiology","volume":null,"pages":null},"PeriodicalIF":0.4,"publicationDate":"2023-03-29","publicationTypes":"Journal Article","fieldsOfStudy":null,"isOpenAccess":false,"openAccessPdf":"","citationCount":null,"resultStr":null,"platform":"Semanticscholar","paperid":"44907535","PeriodicalName":null,"FirstCategoryId":null,"ListUrlMain":null,"RegionNum":0,"RegionCategory":"","ArticlePicture":[],"TitleCN":null,"AbstractTextCN":null,"PMCID":"","EPubDate":null,"PubModel":null,"JCR":null,"JCRName":null,"Score":null,"Total":0}

Thus, decontamination the toothbrush is necessary for oral health. This study aimed to assess the efficacy of different immersion times in chlorhexidine (CHX) for reducing the L. acidophilus contamination of the toothbrush. Methods: This experimental study was conducted on 84 dental students. Primary saliva samples were obtained from the students, and the salivary count of L. acidophilus was measured. The students were assigned to four groups, and the groups were standardized in terms of primary salivary L. acidophilus count: (I) simple rinse of toothbrush with water, (II) simple rinse of toothbrush with CHX, (III) immersion of toothbrush in CHX for 10 minutes, and (IV) immersion of toothbrush in CHX for 24 hours after use. Saliva samples were collected again from the dental students after 3 weeks of practice. The mean L. acidophilus colony counts of primary and secondary saliva samples were calculated. Also, the mean L. acidophilus colony counts of toothbrushes were compared among the four groups. Data were analyzed using ANOVA and Tukey’s tests. The level of significance was set at 0.05. Results: The mean L. acidophilus colony count of toothbrushes was significantly different between the four groups (P<0.05). Groups 3 (P=0.040) and 4 (P=0.012) showed significantly lower toothbrush microbial count compared with Group 1. No significant difference was noted in the salivary colony count of the four groups after the intervention (P>0.05). Conclusion: Immersion of toothbrush in CHX for 24 hours and 10 minutes was more effective than other methods for the reduction of L. acidophilus count of the toothbrush. In order to prevent corrosion of bristles, 10 minutes of immersion is recommended.","PeriodicalId":41793,"journal":{"name":"Journal of Oral Health and Oral Epidemiology","volume":null,"pages":null},"PeriodicalIF":0.4,"publicationDate":"2023-03-29","publicationTypes":"Journal Article","fieldsOfStudy":null,"isOpenAccess":false,"openAccessPdf":"","citationCount":null,"resultStr":null,"platform":"Semanticscholar","paperid":"47376006","PeriodicalName":null,"FirstCategoryId":null,"ListUrlMain":null,"RegionNum":0,"RegionCategory":"","ArticlePicture":[],"TitleCN":null,"AbstractTextCN":null,"PMCID":"","EPubDate":null,"PubModel":null,"JCR":null,"JCRName":null,"Score":null,"Total":0}

The intensity and duration of exercise cause changes in the immune system. S-IgA and cortisol play a key role in maintaining the body’s immunity. This study was performed to investigate the effect of swimming exercise on the immune and hormonal systems of male children with the same caries index in Zanjan, Iran. Methods: In this cross-sectional study, 86 boys 6–12 years old were selected. Based on their duration of training, the children were divided into two groups of 43: The competitive group and the non-competitive group. The group matching method in terms of dental caries, anxiety, and age was performed in the two groups. Stimulated saliva samples were collected to measure S-IgA and cortisol levels by ELISA before and after the swimming test. Independent t test, paired t test, and chi-square test were used for statistical analysis of data, with the significance level set at P<0.05. Results: The amount of S-IgA was higher in the competitive than in the non-competitive group. After swimming training, S-IgA increased in both age groups (28 children aged 6–9 and 58 aged 9–12 years old). In the 6–9 age group, the amount of cortisol in non-competitive boys increased significantly (P=0.048). In the 9–12 age group, the amount of cortisol in the competitive boys decreased. Conclusion: Based on the findings of this study it seems that swimming can increase the amount of cortisol in the 6-9 age group. However, short-term physical activity (swimming test in this study) could not make a significant difference in the immune and hormonal systems of either of the age groups. Further studies are suggested to provide information on changes in the caries index.","PeriodicalId":41793,"journal":{"name":"Journal of Oral Health and Oral Epidemiology","volume":null,"pages":null},"PeriodicalIF":0.4,"publicationDate":"2023-03-29","publicationTypes":"Journal Article","fieldsOfStudy":null,"isOpenAccess":false,"openAccessPdf":"","citationCount":null,"resultStr":null,"platform":"Semanticscholar","paperid":"44888724","PeriodicalName":null,"FirstCategoryId":null,"ListUrlMain":null,"RegionNum":0,"RegionCategory":"","ArticlePicture":[],"TitleCN":null,"AbstractTextCN":null,"PMCID":"","EPubDate":null,"PubModel":null,"JCR":null,"JCRName":null,"Score":null,"Total":0}

As far as we are aware, there haven’t been any thorough epidemiologic research on LC. This study’s objective is to look at the trend of tumor prevalence across the whole lip area in Iranians between 2004 and 2016 (Tehran, Iran). Methods: This retrospective cross-sectional study, which examined tumor location, age, gender distribution, histological tumor type, metastasis, clinical diagnosis, and recurrence of the lesion, was carried out on the pathology records of patients admitted to the Department of Pathology at the Cancer Institutes of Imam Khomeini hospital and Tajrish hospital between 2004 and 2016. The data was analyzed using the chi-square test and Fisher’s exact test. Results: Out of a total of 237392 biopsy reports filed with the Department of Pathology, 512 instances (0.21%, 92% malignant, and 8% premalignant) involving 385 (75.2%) males and 127 (24.8%) females were discovered to be lip-related. A statistically significant difference between sex and the site of the lesion was found using the chi-square test (P=0.032). Lower lip and squamous cell carcinomas (SCC) were the most typical locations and types, respectively. Recurrence and metastasis were noted in 7.8% and 25.84% of cases, respectively, with males more likely than women to experience these outcomes. Moreover, there was a significant (P=0.025) correlation between gender and histological tumor type. Conclusion: The chance of developing LC was greater in men over the age of 54. The most typical location for SCC involvement is the lower lip. We discovered that women had an increased frequency of upper lip lesions. These disparities might be the result of gender-specific professional and behavioral differences. Hence, as possible contributors to the occurrence of LCs, variables including occupational and behavioral variations and public knowledge of sun exposure should be carefully evaluated.","PeriodicalId":41793,"journal":{"name":"Journal of Oral Health and Oral Epidemiology","volume":null,"pages":null},"PeriodicalIF":0.4,"publicationDate":"2022-12-29","publicationTypes":"Journal Article","fieldsOfStudy":null,"isOpenAccess":false,"openAccessPdf":"","citationCount":null,"resultStr":null,"platform":"Semanticscholar","paperid":"43092131","PeriodicalName":null,"FirstCategoryId":null,"ListUrlMain":null,"RegionNum":0,"RegionCategory":"","ArticlePicture":[],"TitleCN":null,"AbstractTextCN":null,"PMCID":"","EPubDate":null,"PubModel":null,"JCR":null,"JCRName":null,"Score":null,"Total":0}

Methods: A web-based data collection form, including demographic characteristics, experience of caries detection systems, and two different clinical images with caries and treatment options, was given to Turkish dental practitioners. Data were analyzed with the chi-square test and logistic regression using SPSS 22.0 software (IBM, Chicago, IL) at a significance level of P<0.05. Results: Data collection forms were completed by 382 general dental practitioners. For the first clinical scenario 70.7% of the practitioners decided that no treatment was required. For the second clinical scenario 89.5% of the practitioners decided to perform tooth restoration. Considering the clinical scenario 2 treatment options, while practitioners working in the public hospital marked amalgam restoration at a higher rate, practitioners working in private clinics marked composite resin restoration and root canal treatment at a higher rate (P<0.05). With regard to effects on treatment choices for clinical scenarios, binary logistic regression analysis found no significant effects of gender, age, or institution (P>0.05).

However, evidence on the sociodemographic risk factors of oral health conditions among BC patients is scarce. This study aimed to investigate the relationship between the socioeconomic status (SES) and dental health in a population of Iranian female BC patients in 2020. Methods: A cross-sectional study was conducted in Kerman, Iran. Indices of decayed, extracted, and filled teeth were measured based on clinical examination by a general dentist. Data were collected through structured face-to-face interviews, review of the patients’ medical records, and clinical examination for six months. Data were analyzed by applying univariate and multivariable generalized negative binomial regression (GNBReg). Data were analyzed using the Stata. Results: Data from 1760 BC patients were collected, 1707 of whom were included in the analysis. The mean age of the participants was 46.3±9.8 years. The mean of the total decayed, missing, and filled teeth, and the number of decayed teeth (DT), missing teeth (MT), and filled teeth (FT) were 12.8±5.8, 3.5±3.1, 4.6±5.2, and 4.6±4.4 teeth, respectively. Regarding SES, the number of participants with high, high-middle, low-middle, and low SES were 421, 432, 395 and 459, respectively. According to univariate analysis, there was no significant difference between different SES in mean DMFT (decayed, missing, and filled teeth), while SES was significantly associated with DT, MT and FT among the study participants. Conclusion: Female BC patients in Iran have lower levels of dental health regardless of their SES. As those from different socioeconomic classes are seeking different and mostly inadequate or unsuitable dental healthcare services, tailored interventional programs are needed to address the dental healthcare needs of patients in each socioeconomic class.","PeriodicalId":41793,"journal":{"name":"Journal of Oral Health and Oral Epidemiology","volume":null,"pages":null},"PeriodicalIF":0.4,"publicationDate":"2022-12-29","publicationTypes":"Journal Article","fieldsOfStudy":null,"isOpenAccess":false,"openAccessPdf":"","citationCount":null,"resultStr":null,"platform":"Semanticscholar","paperid":"42518799","PeriodicalName":null,"FirstCategoryId":null,"ListUrlMain":null,"RegionNum":0,"RegionCategory":"","ArticlePicture":[],"TitleCN":null,"AbstractTextCN":null,"PMCID":"","EPubDate":null,"PubModel":null,"JCR":null,"JCRName":null,"Score":null,"Total":0}

As there are cultural differences and various dietary patterns in different countries, the results of other studies are not necessarily applicable to our society. This study aimed to evaluate the role of some vitamins and dietary patterns in developing head and neck cancer. Methods: Dietary pattern and serum levels of vitamins in 39 patients with head and neck squamous cell carcinoma (HNSCC) were compared to 37 healthy individuals. A native questionnaire was used to obtain the dietary pattern. The existence of a significant relationship between serum levels of vitamins and dietary pattern with the risk of HNSCC was assessed. The independent t test, chi-square and exact Fisher’s test were employed for statistical analysis. Results: The mean serum levels of these vitamins in the case group were significantly lower as compared to the control subjects (P<0.005). Two dominant eating patterns were identified, and after adjusting for confounding factors such as age, education, physical activity, body mass index (BMI), and place of residence, it was found that people with unhealthy dietary patterns were 6.55 times more likely to develop cancer than people with a healthy diet. Conclusion: Lower serum levels of vitamins C and E are associated with an increased risk of HNSCC.
