Adhesion of Candida Albicans to digital versus conventional acrylic resins: a systematic review and meta-analysis

BACKGROUND

The present systematic review and meta-analysis investigated the available evidence about the adherence of Candida Albicans to the digitally-fabricated acrylic resins (both milled and 3D-printed) compared to the conventional heat-polymerized acrylic resins.

METHODS

This study followed the guidelines of the Preferred Reporting Items for Systematic Review and Meta-analyses (PRISMA). A comprehensive search of online databases/search tools (Web of Science, Scopus, PubMed, Ovid, and Google Scholar) was conducted for all relevant studies published up until May 29, 2023. Only in-vitro studies comparing the adherence of Candida albicans to the digital and conventional acrylic resins were included. The quantitative analyses were performed using RevMan v5.3 software.

RESULTS

Fourteen studies were included, 11 of which were meta-analyzed based on Colony Forming Unit (CFU) and Optical Density (OD) outcome measures. The pooled data revealed significantly lower candida colonization on the milled digitally-fabricated compared to the heat-polymerized conventionally-fabricated acrylic resin materials (MD = - 0.36; 95%CI = - 0.69, - 0.03; P = 0.03 and MD = - 0.04; 95%CI = - 0.06, - 0.01; P = 0.0008; as measured by CFU and OD respectively). However, no differences were found in the adhesion of Candida albicans between the 3D-printed digitally-fabricated compared to the heat-polymerized conventionally-fabricated acrylic resin materials (CFU: P = 0.11, and OD: P = 0.20).

CONCLUSION

The available evidence suggests that candida is less likely to adhere to the milled digitally-fabricated acrylic resins compared to the conventional ones.

Individual and community-level factors associated with khat (Catha edulis) use among women of reproductive age in Halaba zone, South Ethiopia: a multilevel mixed effect analysis

Introduction

There is a paucity of data on factors associated with khat chewing among women of reproductive age using multilevel analysis. Furthermore, the effects of some potential factors like stressful life events, knowledge about and attitude toward the effects of khat have been given little attention and are not well understood. Therefore, this study aimed to examine the prevalence and multilevel factors associated with khat use among women of reproductive age in Halaba zone, South Ethiopia.

Methods

A community-based cross sectional study was conducted in Halaba zone from February to July, 2023. Systematic random sampling technique was used to include 1573 study participants. The dependent variable was current khat use, which is operationalized as using khat within 30 days preceding the study. An interviewer administered questionnaire was used for the data collection.

Results

The prevalence of current khat use among women of reproductive age was 65.9% [95%CI (63.5-68.2%)]. Factors significantly associated with khat use were; ages of women 35 and above years [Adjusted Odds Ratio (AOR) = 6.35, 95% CI: (3.62, 11.13)], ever married [AOR = 2.41, 95% CI: (1.10, 5.31)], secondary and above education [AOR = 0.28, 95% CI: (0.15, 0.49)], belong to richer household [AOR = 1.75, 95% CI: (1.12, 2.75)], mass media use [AOR = 3.12, 95% CI: (1.85, 4.81)], low knowledge about khat effects [AOR = 3.12, 95% CI: (1.85, 5.24)], positive attitude towards khat use [AOR = 11.55, 95% CI: (6.76, 19.71)], and strong social support [AOR = 0.43, 95% CI: (0.28, 0.64)] and non-user friend [AOR = 0.31, 95% CI: (0.20, 0.48)]. From the community level variables: rural residence [AOR = 5.06, 95% CI: (1.82, 14.09)] was significantly associated with khat use.

Conclusion

Khat use among women of reproductive age was found to be very high. From individual-level factors: advanced ages of women, secondary and above education, live in the richer wealth quintile, mass media exposure, low knowledge on khat effects, positive attitude towards khat use, strong social support, and from community-level variables: residing in rural area were significantly associated with khat use. Khat use screening for all women of childbearing age, as well as referral to substance use disorder centers for those women identified as having khat use disorder, should become a standard of care in all health facilities.

A Survey of Oral and Maxillofacial Biopsies Over a 23-year Period in the Southeast of Iran

Statement of the Problem

The prevalence of oral and maxillofacial lesions differs in various populations and is an important concern for health care providers.

Purpose

The present study aimed to evaluate the relative frequency and distribution of oral and maxillofacial lesions in patients referred to the Department of Oral and Maxillofacial Pathology, Kerman Faculty of Dentistry in southeast Iran.

Materials and Method

In the present retrospective study, the collected data consisted of age, gender, lesion location, and the clinical and histopathological diagnoses of all the biopsy samples diagnosed in 23 years (1997-2020). The data were analyzed with SPSS 22, using the chi-squared test and ANOVA (p< 0.05).

Results

From 2092 lesions with a definite diagnosis, 1202 (57.5%) and 890 (42.5%) cases belonged to female and male patients, respectively. The mean age of the subjects was 39.06±17.71 years, and the most frequent location of the lesions was the buccal mucosa (25.2%). The frequencies and number of non-neoplastic lesions, neoplasms, and premalignant lesions were 84% (n=1758), 13.3% (n=278), and 2.7% (n=56), respectively. Reactive lesions were the most common cases, with 34.6% (n=724), and lichen planus was the most frequent lesion with 18.1% (n=379). Squamous cell carcinoma was the most frequent lesion in patients >70 years of age (27.6 %).

Conclusion

The present study provided useful data on the frequency and distribution of oral lesions over 23 years and made it possible to compare its results with those of studies carried out in other countries. Non-neoplastic lesions were the most common category, and lichen planus, pyogenic granuloma, and irritation fibroma were the most frequent lesions in descending order.

Anaesthetists' knowledge of airborne infections

Background

Anaesthetists need to be knowledgeable regarding the control of airborne infection to ensure safe practice. The aim of this study was to determine anaesthetists' knowledge regarding airborne infections in the perioperative period in the Department of Anaesthesiology at the University of the Witwatersrand.

Methods

A cross-sectional research design was followed using an anonymous self-administered questionnaire. Data were collected at academic departmental meetings by convenience sampling. Returning the questionnaire implied consent. A score of 65% was considered adequate knowledge.

Results

Of the 150 questionnaires distributed, 137 (91.3%) questionnaires were returned. An overall mean (standard deviation [s.d.]) score of 58.8% (4.252) was achieved, and only 11 (8.1%) of anaesthetists had adequate knowledge. There was no statistically significant association between seniority and passing or failing (p = 0.327). The highest mean (s.d.) score, 67.4% (6.979), was reported in the section pertaining to patients, followed by the section regarding operating theatre staff at 58.1% (11.899) and the lowest mark, 53.5% (5.553), for the environment section. Anaesthetists scored significantly better in the knowledge regarding patients' section than in other sections (p < 0.0005).

Conclusion

Knowledge of airborne infections in this study was poor, with only 8.1% achieving a pass, and no difference in knowledge between junior and senior anaesthetists was observed. Considering the ongoing coronavirus disease 2019 (COVID-19) pandemic at the time of the study, this was a surprising finding. Urgent action needs to be taken to ensure the safety of anaesthetists, other operating theatre staff and patients.

Attitudes and practices of tobacco cessation counseling among Saudi dental professionals: A nationwide cross-sectional survey

Background

Dental professionals can play a pivotal role in educating the public about the harmful effects of smoking and encouraging them to quit the habit.

Aim

This study assesses the attitudes and practices of tobacco cessation counseling (TCC) among dental professionals in Saudi Arabia.

Patients and Methods

This questionnaire-based cross-sectional study targeted dentists and dental interns working in government and private sectors in Saudi Arabia. We conducted a descriptive analysis by using SPSS Statistics, version 25.0.

Results

A total of 895 respondents (314 interns and 581 dentists) participated in this survey. Although the majority of respondents (93%) reported that they always ask patients about tobacco habits, only 59% reported recording tobacco habits in patients' files, and only 55% of the respondents reported explaining to patients the harmful effects of tobacco. Around 91% of the participants believe that a dental clinic is an appropriate place for TCC, and 22% believe that TCC has a negative impact on dental practice. Smoking status, work setting, and the number of years since graduation were found to be significantly associated with the respondents' attitudes and practices. Lack of training, time limitations, and lack of confidence were barriers for TCC.

Conclusions

Dental professionals in Saudi Arabia demonstrated relatively positive attitudes but weak practices of TCC. Continuous education and motivation are needed to improve dentists' confidence, attitudes, and willingness for TCC. Integration of tobacco control education in undergraduate curricula is recommended.

Prevalence of Oral Normal Variance in Healthy Elderly Patients: A Descriptive Study on Oral Pseudo Lesions

Introduction The aging process in the elderly can change the condition of the oral cavity, regarding both clinical appearance and function. The oral mucosa becomes more susceptible to mechanical damage and irritant agents. Any changes in the oral mucosa, including normal variance, should be examined. This is especially true for the elderly, to improve oral health and prevent any abnormalities.

Objective To describe the prevalence of oral normal variance in healthy elderly patients.

Methods An observational descriptive study with a cross-sectional design with total sampling conducted from March to April 2020.

Results Among the 117 elderly patients who participated in this study, 58 were described as healthy without any comorbidities. From those subjects, there were 117 cases of normal variance in the oral mucosa. The three most prevalent issues were fissured tongue (93.1%), coated tongue (58.62%), and crenated tongue (27.59%).

Conclusion Fissured tongue is a normal variance of the oral mucosa that is commonly found in healthy elderly patients.

Clinical Study of Oral Mucosal Lesions in the Elderly-Prevalence and Distribution

BACKGROUND

The aim of the study was to determine the prevalence, pattern, and distribution of oral mucosa lesions in elderly patients attending an outpatient oral pathology clinic.

METHODS

A retrospective analysis of 2747 patients' medical files was performed. Of these, 1398 (50.6%) belonged to seniors. The mean age was 69.8 ± 7.1, and women were in the majority.

RESULTS

Among the entire group of patients, the three most common mucosal lesions were: oral lichenoid diseases (OLDs), lingual changes, and small nodules. In the female group, the most common diagnoses were: OLDs, lingual changes, and oral candidiasis; in the male population, the most common diagnoses were: lingual changes, small nodules, and OLDs. Those suffering from OLDs were the youngest patients, and those with focal oral mucosa erosions and ulcerations were the oldest patients. In the groups aged 60-70 and 71-80 years old, the most common diagnoses were OLDs, and in the oldest group (+80 years old), they were lingual lesions.

CONCLUSIONS

Oral health has an obvious impact on the functional, psychological, and behavioral quality of life. There is a small number of publications concerning the prevalence and distribution of oral mucosa lesions in the senior population of European countries. Our study is filling in that void.

Dental Students in Egypt: To What Extent Do They Perceive and Comply with Infection Control Measures?

This study was carried out in the dental school of Ahram Canadian University in Egypt to investigate the knowledge and compliance of senior students and interns toward infection control practices. A self‑administered questionnaire was employed with questions pertinent to the participants’ knowledge of risks in the dental settings, the practice of hand hygiene, the use of protective equipment, and the management of sharp injuries, among others. Although the knowledge and practice of the 240 surveyed participants were good; they were not up to the coveted standards. Despite being an integral part of their curriculum, an alarming percentage (19.6%) of the participants denied receiving knowledge about infection control instructions. Meanwhile, only 72.5% were aware of being at risk in the dental settings, and 78.3% confirmed their practice of hand hygiene. On the other hand, 84.6% of the surveyed participants confirmed the availability of protective equipment and 94.2% of them expressed their willingness to apply infection control measures in the future. The defects in the knowledge and practice mandate corrective actions to promote and upgrade the students’ compliance. Meanwhile, other gaps can be rectified via developing state-of-the-art communicative strategies. Efforts are warranted to enhance the attitude and motivate the students to conform to the protective safety measures. With all the infection control procedures already established in dental schools, the challenge lies in improving the students’ compliance with these recommendations.

Xerostomia, Salivary Flow, and Oral Health Status Among Saudi Diabetic Patients: A Comparative Cross-Sectional Study

Purpose

Diabetes mellitus (DM) is associated with numerous oral complications, including frequent oral infections, periodontal diseases, hyposalivation, and xerostomia. The present study aimed to investigate salivary flow rate, xerostomia, and oral health status among a group of Saudi diabetic patients as compared to healthy controls.

Patients and Methods

This comparative cross-sectional study involved 50 diabetic patients (aged between 15 and 70 years) and 53 age- and gender-matched healthy controls. Data collection was carried out using a structured questionnaire and clinical examination of oral health status, which included salivary flow rates, saliva pH, tooth loss, plaque accumulation, and gingival health. Independent t-tests, one-way analysis of variance (ANOVA), and chi-square tests were performed to compare between groups.

Results

The results revealed a statistically significant lower salivary flow (0.33 ± 0.16 vs 0.59 ± 0.54; p = 0.002) and lower saliva pH (6.36 ± 0.49 vs 6.58 ± 0.39; p = 0.014) in diabetic patients than in the control group. A higher proportion of diabetic subjects (60%) self-reported having xerostomia compared to controls (52%), but the findings were statistically non-significant. Additionally, the results revealed slightly poorer oral health and greater tooth loss among DM patients, although the results did not attain a significant difference (P > 0.05).

Conclusion

The findings of the present study demonstrate poor oral health and a high prevalence of xerostomia among Saudi diabetic patients. Oral health education should therefore be promoted in this group of patients.

Prevalence of Oral Mucosal Lesions Among the Institutionalized Elderly Population in Lebanon

This study aimed to determine the prevalence of oral mucosal lesions and risk factors among the institutionalized elderly Lebanese population. A representative sample of 526 individuals (49% males and 61% females) aged 65 years and above was examined. A questionnaire and clinical examination were administered. Bivariate and multivariate regressions were carried out. The frequency of oral mucosal lesions was 22.8% and it was associated to the use, integrity (p < .002), and hygiene level (p < .047) of removable mandibular and maxillary prosthesis. Multiple regression analysis also predicted the relationship between the mandibular prosthesis hygiene level and the occurrence of mucosal lesions. The factors controlling the occurrence of oral mucosal lesion were mainly related to the level of oral care given to the individuals. Therefore, a proper oral health care system should be implemented in the Lebanese residential homes to ensure the well-being of the residing population.

Oral and maxillofacial lesions in older individuals and associated factors: A retrospective analysis of cases retrieved in two different services

BACKGROUND

Studies on the oral and maxillofacial lesions (OMLs) in older people usually assess data of laboratory services and data from oral medicine clinic have been poorly described. The aim of this study was to describe and to compare OMLs in older individuals considering two data sources, besides to assess associated factors with the three most frequent lesions.

MATERIAL AND METHODS

A retrospective study was conducted with individuals aged 60 years or older. Data of individuals and lesions reported in both services were collected. Univariate analysis was used to test the association between the occurrence of the lesion and the independent variables. The level of significance was set at 5%.

RESULTS

A total of 1,695 (37.3%) records were from the Oral Medicine clinic and 2,848 (62.7%) from the Laboratory service. Inflammatory/reactive lesion group was the most frequent in both services (40.4% in Oral Medicine Clinic and in 44.2% Laboratory). The second and third groups of lesions in the Oral Medicine clinic were infectious diseases (18.5%), and variations of normality (10.8%), while in the laboratorial service were the malignant neoplasms (17.6%) and potentially malignant disorders (13.3%). Differences between services regarding the frequency of lesion groups occurred (p<0.05), except for pigmented (p=0.054) and infectious (p=0.054) groups. Females (OR: 2.08; CI: 1.81-2.39) and individuals who wore a removable prosthesis (OR: 3.99; CI: 2.83-5.62) were also likely to have inflammatory fibrous hyperplasia. Old-old individuals (OR: 1.70; CI: 1.30-2.21), male (OR: 3.63; CI: 3.00-4.39), smoking (OR: 6.05; CI: 4.84-7.56) or alcohol use (OR: 3.95; CI: 3.12-5.01) were likely to have squamous cell carcinoma.

CONCLUSIONS

The results showed different frequencies of OMLs in older individuals according to the data sources and age group. The findings are important to direct public policies for this age group. Key words:Oral medicine, laboratory service, older adult, oral diagnosis, oral and maxillofacial pathology.

Characteristics of patients who perceive dental treatment as a cause of oral mucosal lesions

This retrospective study aims to investigate the proportion and characteristics of patients who perceive dental treatment (DT) as a cause of oral mucosal lesions (OMLs). A total of 2,302 patients with OMLs visited the Oral Medicine Department of Pusan National University Dental Hospital. The patients were divided into a study group (280 patients who perceived DT as a cause of OMLs) and a control group (300 randomly selected patients). Percentages of DT types, clinical characteristics, and the frequencies of diagnoses and chief complaint (CC) sites were analyzed in both groups. Among the patients with OMLs, 12.2% attributed OMLs to DT. Among the diagnoses, allergic reaction (AR) and traumatic ulcer/irritation (TU) were significantly more frequent in the study group. The DT types most frequently perceived as the cause of OMLs were implants. According to patients, TU and candida occurred most frequently following denture placement (68-79%), whereas oral lichen planus and AR occurred most commonly following implant treatment (52-53%). The gingiva was significantly more frequent as the CC site in the study group than in the control group (P < 0.05 for all outcomes). It is important to inform patients of the potential complications of DT and the importance of regular check-ups.

White oral mucosal lesions among the Yemeni population and their relation to local oral habits

AIMS

The aim of the present study was to assess the prevalence and risk factors of white oral mucosal lesions among Yemeni adults; in particular, those who chew khat and tobacco.

METHODS

The present cross-sectional study included 1052 dental patients aged 15 years and older. A detailed oral examination was performed by a single examiner in accordance with standard international criteria.

RESULTS

Overall, 25.2% of the study participants presented with one or more white lesions. The most prevalent lesions were khat-induced white lesion (8.8%), leukoedema (5.1%), and frictional keratosis (3.9%). Potentially malignant lesions, such as lichen planus, leukoplakia, and smokeless tobacco-induced lesions, were seen in 2.4%, 1.2%, and 1.7% of participants, respectively. Moreover, three cases of oral cancer were identified. The presence of white lesions was found to be significantly associated with advanced age (P = .004), male gender (P = .009), and khat/tobacco chewing habits (P < .001).

CONCLUSIONS

The present study demonstrates a high prevalence of oral benign and potentially malignant white lesions. Further, it highlights the urgent need to develop and implement new government policies to regulate the sale of these products to reduce the prevalence of these lesions and the overall incidence of oral cancers in the Yemeni population.

Is Khat (Catha edulis) chewing a risk factor for periodontal diseases? A systematic review

Background

Khat (Catha edulis) chewing is a highly prevalent habit in the Arabian Peninsula and East Africa, and has recently spread to Western countries. The association between khat chewing and oral mucosal lesions is well documented in the literature. However, there is no concrete evidence on the association between khat chewing and periodontal disease. The purpose of this systematic review was to analyze the influence of khat chewing on periodontal health.

Material and Methods

A literature search of PubMed, Scopus and Web of Sciences databases was carried out to identify relevant articles published from 1990 to May 2017. The inclusion criteria were all clinical studies that assessed the relationship between khat chewing and periodontal disease.

Results

The search yielded 122 articles, of which 10 were included in this systematic review. Most of the studies exhibited a positive correlation between khat chewing and periodontal disease.

Conclusions

Altogether, the analysis of the current evidence reveals that khat chewing is destructive to the periodontium and enhances the risk of periodontal disease progression. However, due to variability of studies, more longitudinal case-controlled studies are highly warranted to establish a causal relation between khat chewing and periodontal disease.

Key words:Khat chewing, periodontal health, periodontal disease, risk factor.

Khat (Catha edulis) and its oral health effects: An updated review

Khat or qat (Catha edulis) is a plant that grows in East Africa and southern Arabia. The leaves and twigs of this small tree are chewed by several millions of people worldwide for their stimulating amphetamine-like effects. The reported prevalence of khat chewing in Europe and the USA is on the rise, especially with global migration. Long-term khat chewing has several detrimental general and oral health effects. The aim of the present study was to review the current literature regarding khat use and its association with oral and dental diseases, with particular emphasis on its link with oral keratotic white lesions and oral cancer. We searched the literature to identify all relevant articles. Studies showed that khat is associated with several oral and dental conditions, including keratotic white lesions, mucosal pigmentation, periodontal disease, tooth loss, plasma cell stomatitis, and xerostomia. There are limited data on the incidence of dental caries among khat chewers. The evidence that khat chewing is a risk factor for oral cancer is still weak, and is mainly based on anecdotal case reports and uncontrolled studies.

Oral hygiene and periodontal health status among khat chewers. A case-control study

Background

Habitual khat chewing is a widespread male habit in Southern Arabia and East Africa. The aim of this study was to assess the effect of Khat chewing on oral hygiene and periodontal health status among Yemeni male khat chewers.

Material and Methods

This case- control study included 310 khat chewers, aged 20-65 years, and 72 age- and gender- matched non-chewers as controls. Periodontal examination included recording of dental plaque index (PI), gingival index (GI), probing pocket depth (PPD), attachment level (AL) and gingival recession (GR). Demographic data, oral hygiene practices, and duration, frequency and site of khat chewing were obtained using questionnaires. SPSS was used for data analysis. ANOVA and t- tests were used to compare groups.

Results

Khat chewers had significantly higher mean PI, AL, GR scores than non-chewers (P < 0.05). However, no significant differences in the GI and PPD mean scores were observed between both groups (p > 0.05). Interestingly, the results showed that the chewing side had less PI, GI and PPD than non-chewing side. However, gingival recession was significantly higher in the chewing side. The duration of chewing showed a significant effect on PI, PPD, AL, and GR but had no effect on the gingival condition. Likewise, the frequency of chewing showed a significant effect on PPD, AL, and GR, but had no effect on other indices (PI and GI).

Conclusions

The results of this study indicate that khat chewing have a detrimental effect on the periodontium.

Key words:Khat chewing, periodontal health, oral hygiene.

Urban and rural disparity in tobacco use and knowledge about oral cancer among adolescents: An epidemiological survey on 12 and 15-year school going students

Aims and Objectives:

To assess and compare the tobacco use prevalence; to understand and compare attitudes and knowledge related to tobacco use and its health impact among urban and rural students; and to assess urban and rural disparity in the use of tobacco among 12 and 15-year-old adolescents in the urban and rural schools in Chhattisgarh, India.

Materials and Methods:

A cross-sectional study was conducted among 12 and 15-year-old and urban and rural school going children in Durg District. Scientifically, based on the data obtained from the pilot study, sample size was calculated. A total of 1000 children were selected to be a part of the study and were interviewed face-to-face using a detailed pretested, close-ended questionnaire. The Statistical Package for the Social Sciences version 16.0 (SPSS Pvt. Ltd, Chicago, IL, USA) was used for the statistical analyses.

Results:

Prevalence of tobacco consumption was 48.8%. Males were involved predominantly in consuming tobacco. The knowledge and attitude was better in the school children of urban areas than the school children of rural areas; more of the urban school children were involved in smoking cigarette. Rural children outnumbered urban children in the smokeless tobacco consumption.

Conclusion:

Prevalence of tobacco consumption among school children remains high with a wide disparity among urban and rural children. There is an urgent need to have a rural orientation in the National Tobacco Control Program that is currently being developed by the Government of India and giving relevance to the youth.

Oral mucosal lesions in a Chilean elderly population: A retrospective study with a systematic review from thirteen countries

BACKGROUND

The oral examination is an essential part of the multidisciplinary medical care in elderly people. Oral mucosal lesions and normal variations of oral anatomy (OMLs) are very common in this people, but few studies have examined the frequency and prevalence of these conditions worldwide and less in Chile. The aim of this research was to evaluate the frequency of OMLs in a Chilean elderly population.

MATERIAL AND METHODS

It was conducted a retrospective study (Talca, Chile). Two hundred seventy-seven OMLs were classified in groups and anatomical sites. In order to contextualize our numbers, we made a systematic review using Publish or Perish software, Google Scholar and InteractiVenn.

RESULTS

The most prevalent OMLs groups were soft tissue tumors, epithelial pathology, facial pain and neuromuscular diseases, and dermatologic diseases. The most frequent OMLs included irritation fibroma (30 patients, 10.8%), hemangioma (20, 7.2%), burning mouth syndrome (20 cases, 7.2%), oral lichen planus (12, 4.3%) and epulis fissuratum (12, 4.3%). In the systematic review, 75 OMLs were relevant and the more studied pathologies were traumatic ulcerations (11 of 15 articles), oral lichen planus (10/15), irritation fibroma, melanotic pigmentations, and recurrent aphthous stomatitis (9/10, respectively). Considering all included articles, most frequent OMLs in elderly people included denture-related stomatitis (13.3%), irritation fibroma (8.7%) and fissured tongue (6.3%).

CONCLUSIONS

The results reflect the frequency of OMLs diagnosed in a specialized service in south of Chile and many countries around the world. These numbers will allow the establishment of preventive politics and adequacy of the clinical services. Key words:Oral mucosal lesions, elderly people, Chilean population, frequency, systematic review.

Prevalence of denture-related oral lesions among patients attending College of Dentistry, University of Dammam: A clinico-pathological study

Background:

Heterogeneous groups of oral lesions are likely to develop among denture wearers. The objectives of this study were to determine the exact prevalence of oral lesions among denture wearers attending the clinics of the College of Dentistry, University of Dammam.

Materials and Methods:

All denture wearers attending the dental clinics in the period between January 2012 and April 2013 were included in this study. Of the total 210 patients, 166 (79%) were males and 44 (21%) were females. Comprehensive oral examination was performed for all patients. Any denture-induced lesion was biopsied. Data collected were analyzed using SPSS program.

Results:

Oral lesions were found in 20.5% of the cases under study (43 out of the total 210 denture wearers). Denture-induced fibrous hyperplasia was the most common type of lesion detected (41.9%). A significant correlation (P = 0.004) was found between the type of denture and oral lesions in this study.

Conclusion:

The prevalence of denture-induced oral lesions was found to differ significantly from that reported in other studies. The diversity of these lesions among different studies depends on the quality and materials of dentures delivered, the techniques used, and the methods of patients’ instructions adopted.

Periodontal Health Condition and Associated Factors among University Students, Yemen

INTRODUCTION

Studies on oral health status among Yemeni population are scarce.

AIM

This study aimed to evaluate the periodontal health among advantaged section of Yemeni society, university students, in health and non-health fields.

MATERIALS AND METHODS

Periodontal health status of a sample of 360 students from dental, medical and literature faculties (120 each with equal gender distribution) at Sana'a University was evaluated by two calibrated examiners using CPI index. Data regarding tooth-brushing practices and smoking and khat chewing habits were obtained using a structured interview questionnaire.

RESULTS

Only 45 students (12.5%) had healthy periodontium, while 113 (31.4%), 186 (51.7%) and 16 (4.4%) had bleeding, calculus and shallow pocket, respectively, with no significant differences between faculties. Females revealed significantly better periodontal health compared to males, though their bleeding score was higher. Dental and medical students and female students in general were significantly more interested in tooth-brushing and significantly less interested in practicing the deleterious habits such as smoking and khat chewing.

CONCLUSION

The overall periodontal health of Sana'a University students is still unsatisfactory even among students in health field. Females and students in health field revealed better periodontal health and oral health practices (tooth-brushing) in comparison to male students and those in non-health field. The negative effects of the highly prevalent smoking and khat chewing habits deserve further reliable researches and proper educational programs at the national level.

Benign Orofacial Lesions in Libyan Population: A 17 Years Retrospective Study

Objectives:

To analyze the frequency and type of benign orofacial lesions submitted for diagnosis at Tripoli Medical Centre over 17 years period (1997-2013).

Materials and Methods:

Entries for specimens from patients were retrieved and compiled into 9 diagnostic categories and 82 diagnoses.

Results:

During the 17 years period, a total of 975 specimens were evaluated, it comprised a male-female ratio of 0.76:1. The mean age of biopsied patients was 36.3±18.32 years. The diagnostic category with the highest number of specimens was skin and mucosal pathology (22.87%); and the most frequent diagnosis was pyogenic granuloma (14.05%).

Conclusion:

Pyogenic granuloma, lichen planus, radicular cyst and fibroepithelial polyp were found to be the most predominant diagnoses. Frequencies of most benign orofacial diseases were comparable to similar studies in the literature and to those reported from the eastern region of Libya. Further surveys are needed to define the epidemiology of orofacial diseases in Libyan population.
