The association between referral by specialists in oral diagnosis on survival rates of patients with oral cancer: A retrospective cohort study.

BACKGROUND: To assess the influence of diagnosis and referral provided by specialists in oral diagnosis on disease-free survival and overall survival of patients with oral cancer. METHODS: A cohort of 282 patients with oral cancer treated at a regional cancer hospital from 1998 to 2016 was analyzed retrospectively. The referral register of the patients was analyzed and assigned to two groups: (1) those referred by oral diagnosis specialists (n = 129), or (2) those referred by nonspecialized professionals (n = 153). The cancer treatment evolution was assessed from the patients' records, and the outcome was registered concerning cancer recurrence and death. Sociodemographic and clinicopathological variables were explored as predictors of disease-free survival and overall survival. RESULTS: Group 1 exhibited lower T stages and a reduced incidence of regional and distant metastases. Surgery was performed in 75.2% of cases in Group 1, while in Group 2, the rate was 60.8%. Advanced T stages and regional metastases reduced the feasibility of surgery. Higher TNM stages and tumor recurrence were associated with decreased disease-free survival, while surgical intervention was a protective factor. Higher TNM stage had a negative impact on the overall survival. CONCLUSION: Specialized oral diagnosis did not directly impact disease-free survival and overall survival and did not influence the indication of surgery in oral cancer; however, it was associated with the diagnosis of early tumors and better prognosis.

Structural brain feature is associated with changes of masticatory performance in healthy elderly people: Evidence from longitudinal neuroimaging research over two years.

BACKGROUND: Human neuroimaging studies have revealed the association between brain structure and masticatory function. However, the majority of the studies adopted a cross-sectional design, which hardly reveals the change in masticatory function and brain structure between different timepoints, and the dynamical association between changes in masticatory function and changes in brain structure has not been elucidated. OBJECTIVE: With a longitudinal design, we assessed the association between changes in masticatory performance (MP) and regional brain volume. METHODS: Twenty-two elderly participants received assessments of the number of missing teeth and MP (via colour-changeable chewing gum) when they entered the study (i.e. the initial stage, T0 ), approximately 6 months later (T0.5 ), and approximately 1-2 years later (T1 ). Difficulty of food intake was assessed using a questionnaire. The participants received magnetic resonance imaging (MRI) at T0 and T1 . The brain volume of the motor-related area was estimated using FreeSurfer for MRI data. The associations between different stages were analysed using Spearman's rho correlation coefficients. RESULTS: (1) Individually, a smaller volume of right primary motor cortex at T0 was associated with increased MP from T0 to T1 , suggesting the brain's role in changing oral functions; (2) higher MP at T0 was associated with an increased volume of the left superior frontal cortex from T0 to T1 p, suggesting a potential effect on brain plasticity, and (3) increased difficulty to eat was associated with decrease MP but not brain volume of motor-related area. CONCLUSIONS: The preliminary findings revealed a complicated pattern of structural brain features and masticatory function in elderly people, and either the hypothesis that the brain predisposes masticatory function or the hypothesis that mastication reshapes the brain is oversimplified.

The development of an online serious game for oral diagnosis and treatment planning: evaluation of knowledge acquisition and retention.

BACKGROUND: While serious games seem to be supportive in healthcare education, none of them had been designed to develop competence in diagnosis and treatment planning of oral lesions. Therefore, this research aimed to develop an online simulation-based serious game for training diagnosis and treatment planning of oral lesions (SimOL) and to evaluate its educational impact in terms of knowledge improvement and retention. METHODS: As a mandatory task in an oral lesion course, all 28 students were required to participate in SimOL activities. Participants were instructed to complete a pre-knowledge assessment following a one-week washout period prior to the game activity. Subsequent to the game completion, they were tasked to complete a post-knowledge assessment I (Full score = 15) and satisfaction questionnaire. A post-knowledge assessment II was administered a week later to evaluate knowledge retention. RESULTS: The findings demonstrated a significant increase in the assessment scores after interacting with the game (P < 0.001), where the pre- and immediate post-knowledge assessment scores were 8.00 (SD = 2.11) and 11.71 (SD = 2.39), respectively. The game also exhibited a positive impact on knowledge retention, as there was no significant difference between the scores of post-knowledge assessment I and II (P > 0.05). Additionally, students perceived the game as positively in all aspects, although the entertainment aspect achieved a slightly lower score of 3.70 (SD = 0.21), in comparison to the usefulness and ease of use with a score of 4.02 (SD = 0.11) and 4.02 (SD = 0.16), respectively. CONCLUSION: SimOL demonstrated its potential as an effective learning tool for improving and retaining knowledge for diagnosis and treatment planning of oral lesions. The game was perceived positively by dental students in all aspects, however further improvements should prioritize the enhancement of entertaining components.

Effects of lesion size on the 30-month clinical performance of restorations with bulk fill and a regular nanofilled resin composite in noncarious cervical lesions.

OBJECTIVE: The aim of this double-blind, randomized trial was to evaluate the influence of the occlusogingival distance (OGD) in noncarious cervical lesions (NCCLs) on the clinical performance of a regular bulk-fill resin composite and a regular nanofilled resin composite. MATERIALS AND METHODS: One hundred and forty NCCLs in 77 participants were randomly divided into four groups (n = 35), according to OGD (1.5 mm ± 10% or 3 mm ± 10%) and resin composites (Filtek Bulk Fill Posterior [B] or Filtek Z350 XT [C]), namely: 1.5 mm-B, 1.5 mm-C, 3 mm-B, and 3 mm-C. The restorations were bonded using a two-step self-etch adhesive (Clearfil SE Bond), applied following the manufacturer's instructions. Restorations were polished 1 week after placement. Two experienced and calibrated examiners evaluated the restorations using modified US Public Health Service criteria at baseline (7 days) and after 6, 12, 18, 24, and 30 months. Statistical analyses were carried out using Kruskal-Wallis, Friedman's repeated measures analysis of variance, and the Wilcoxon signed rank test (α = 0.05). RESULTS: After 30 months, the recall rate was 94.2%. Eight restorations were lost (3 for 1.5 mm-C, 2 for 1.5 mm-B, 1 for 3 mm-C, and 2 for 3 mm-B). All groups resulted in a significantly worse marginal discoloration and surface texture at 30 months in comparison with the baseline (1 week). No significant difference was found for the other parameters. CONCLUSION: The restorations performed with both resin composites produced clinically acceptable restorations. The OGD of NCCLs did not influence the clinical performance of restorations. CLINICAL SIGNIFICANCE: The OGD of NCCLs did not have a significant effect on the clinical performance of a regular bulk-fill and nanofilled restorations. Both materials showed a very good performance on 30-month evaluation.

Radiographic ratios for classifying furcation anatomy: proposal of a new evaluation method and an intra-rater and inter-rater operator reliability study.

OBJECTIVES: Even if it seems to be an important anatomical parameter for tissue regeneration, few studies in literature evaluate the "mean measure" of root divergence. Most of them are linear measurements, which hardly describe the dental furcation conformation in its entirety. It is left to the subjectivity of the operator deciding whether a furcation is convergent or divergent. The goal of this study is to create a visual evaluation method using specific measurements applied on endo-oral X-rays to overcome these problems, giving a conformation of the entire interradicular space and its divergence. MATERIAL AND METHODS: A user-friendly software (Paint®, Windows10®) was used to take three different measurements on endo-oral radiographs of upper and lower molars. Three blind operators measured 20 radiographs, to analyze the intra- and inter-operator reproducibility of the measurements. Then, the technique was repeated on 250 radiographic images to identify an average value and define a main conformation of the interradicular space. The ratio of these three measurements allowed to develop a new visual evaluation method of the interradicular space. RESULTS: Intra and inter-operator reproducibility was statistically confirmed on a sample of 20 anonymous endo-oral radiographs measured by 3 blind operators, indicating that the measurement technique was not operator dependent. Measurement made on 250 X-rays obtained with this technique permitted to subdivide in five groups the conformation of the interradicular space and define a mean value of the interradicular space. CONCLUSIONS: A new anatomical evaluation of the interradicular space in its entirety, which could help the clinicians in diagnostic and decisional phase in the therapy of furcated molars, can be obtained. CLINICAL RELEVANCE: A pre-operative evaluation of interradicular space conformation could affect therapy treatment choice.

Teledentistry: A Future Solution in the Diagnosis of Oral Lesions: Diagnostic Meta-Analysis and Systematic Review.

Introduction: Teledentistry (TD) can offer a wide range of possibilities in the field of oral medicine. Oral potentially malignant disorders (OPMDs) are hard to detect, and even harder to diagnose correctly. With the help of TD, OPMDs can be detected and diagnosed by a remote specialist. Our aim was to investigate whether TD could provide a reliable diagnostic method compared with clinical oral examination (COE) in the diagnosis of OPMDs. Methods: A systematic search was conducted in three databases (Medline, EMBASE, CENTRAL) until November 2021. We included studies that compared telediagnosis and COE, both made by experts. Pooled specificity and sensitivity were calculated and visualized on a two-dimensional plot. Risk of bias was assessed using the QUADAS-2 tool, and the level of evidence is shown with the Grades of Recommendation, Assessment, Development and Evaluation (GRADE) tool. Results: Of the 7,608 studies, 13 were included in the qualitative and 9 in the quantitative synthesis. Using TD tools in the detection of oral lesions (OLs) showed high specificity (0.92 confidence interval [95% CI] = 0.59-0.99) and sensitivity (0.93 95% CI = 0.17-1.00). In the differential diagnosis of lesions, we found high sensitivity and specificity (0.942 95% CI = 0.826-0.982 and 0.982 95% CI = 0.913-0.997), respectively. We summarized the available data on time-effectiveness, screening person, referral decision, and technical settings. Conclusion: Detecting OLs with TD tools might lead to earlier diagnosis, treatment, and stricter follow-up of OPMD. TD may offer a great substitution for COE in the diagnosis of OLs, and thus, fewer referrals could be made to special care, resulting in a greater number of treated OPMDs.

Burning mouth disorder and Parkinson's disease: A scoping review of the literature.

BACKGROUND: Burning mouth disorder (BMD) is a complex medical condition characterized by a burning sensation in the mouth of fluctuating intensity. BMD is considered a diagnosis of exclusion, as oral burning can occur secondary to local or systemic conditions. Parkinson's disease (PD) is one such condition. OBJECTIVE: To provide a scoping review of the literature by assessing all articles written in English that investigated the relationship between BMD and PD. MATERIALS AND METHODS: Various databases (PubMed, Ovid, Web of Science, Science Direct and Scopus) and a search platform (EBSCOhost) were searched following similar investigative approaches. Duplicates were removed and reference lists of original studies were scrutinized for additional articles. Any decision about the inclusion/exclusion in the review was by consensus among the co-authors. RESULTS: Twenty-five original articles and one supplemental article were included in the final review, of which 13 met the inclusion criteria. These were further divided into five categories based on the study design/article, which included Prevalence studies (n = 6), Letter to the editor (n = 1), Incidence study (n = 1), Case reports (n = 2) and Experimental studies (n = 3). Strongest data was provided by epidemiological studies, which suggest BMD and PD are poorly associated. CONCLUSIONS: A scoping review of the existing literature does not suggest that PD patients are any more at risk of developing BMD compared to the general population. While there may be a link through the dopaminergic system as determined by imaging studies, it is unlikely that the pathogenesis of PD disease shares significant commonality with BMD.

Care-resistant behaviour during oral examination in Dutch nursing home residents with dementia.

OBJECTIVE: To assess the occurrence and associations of verbal and non-verbal care-resistant behaviour (CRB) during oral examination by a dental hygienist in nursing home residents with dementia. BACKGROUND: CRB is a barrier to providing professional oral care and daily oral hygiene care. Understanding the predictors of CRB might help care professionals in learning to anticipate this behaviour. METHODS: In this multicentre cross-sectional study signs of verbal and non-verbal CRB were reported during the oral examination. Data collection occurred in the psychogeriatrics wards of 14 different nursing homes in the Netherlands (N = 367). RESULTS: A total of 367 residents were included. CRB was evident in 82 residents (22.3%), of whom 45 (55%) showed verbal and 37 (45%) non-verbal CRB. Associated with CRB were age >85 years, duration of residential stay longer than 2 years, and having Korsakov dementia. Other factors associated with CRB were duration of residential stay (categories ">2 and ≤4 years" or ">4 years") and having a natural dentition (P = .043-.005, OR = 1.20-1.33, 95% CI = 1.00-8.48). Significant associations for verbal and non-verbal CRB were age between 76 and 85 years, vascular dementia and Korsakov dementia (P = .031-.006, OR = .020-1.49, 95% CI = 0.43-2.15). CONCLUSION: The occurrence of CRB was 22.3% and was associated with older age and longer duration of residential stay, Vascular and Korsakov dementia and natural dentition.

Misconceptions about Oral Diagnosis and Radiology among Dental Students: A Questionnaire Study.

BACKGROUND: Misconceptions are learning deficits that may cause clinical judgments in a dental practice to be made incorrectly. AIM: This study aimed to identify and look into students' misconceptions regarding Oral Diagnosis and Radiology. MATERIALS AND METHODS: The fourth and fifth-grade students at the Altinbas University Faculty of Dentistry were given a self-administered questionnaire that included multiple-choice questions about Oral Diagnosis/Medicine and Radiology. 106 students participated in the questionnaire and 50.9% of the participants were fourth-grade students, 49.1% of them were fifth-grade students. The questions were classified into two parts: five scenario-based questions and ten knowledge-based questions. Students' replies were evaluated for accuracy and confidence, and when a student was certain of giving an inaccurate response, misconceptions were noted. Two groups were compared using the Mann-Whitney-U test (P = 0.05). RESULTS: A total of 1590 responses were collected. Regarding the question type, scenario-based questions had more misconceptions (19.6%) than knowledge-based questions (18.4%). Depending on the question, the majority of misconceptions were seen in the questions about denture stomatitis (46.2%) and radiographic contrast (38.7%). CONCLUSIONS: To prevent misdiagnosis, it is essential to recognize and overcome misconceptions in Oral Diagnosis/Medicine and Radiology. Therefore this study assists students and lecturers in defining misconceptions and organizing precautions to avoid and fix them.

John Greenwood's sidenotes on a 1778 John Hunter text at The New York Academy of Medicine.

John Greenwood (1760-1819) was George Washington's preferred dentist. He practiced in New York and made at least one of eight sets of dentures Washington wore (currently in the collection of the New York Academy of Medicine (NYAM). We know very little about John Greenwood's (JG) formal education, except that he came from a famous family of dentists. He inherited from his father, Isaac Greenwood, one important book of the time, John Hunter's 1778 treatise, A Natural History of the Human Teeth. That copy was donated to the New York Academy of Medicine by descendants of John Greenwood. Recently, we became aware of extensive marginalia that John Greenwood wrote in this book. The present article describes John Greenwood's opinion on a variety of dental subjects such as the causes and mechanisms of tooth destruction and gum disease and the presence of microscopic annamalcula that were thought to be connected to poor oral hygiene. Although John Greenwood was self-educated, his observations are surprisingly insightful and at least 37 years ahead of what was described in the contemporary literature.

Diagnostic performance of the AAP/EFP classification and the CDC/AAP case definition among pregnant women and a practical screening tool for maternal periodontal diseases.

BACKGROUND AND OBJECTIVE: There is a limited number of studies on the performance assessment of the 2017 AAP/EFP classification and the CDC/AAP case definition among pregnant females. This study evaluated the agreement between these two systems and explored a practical tool for screening maternal periodontal diseases by general dentists. MATERIALS AND METHODS: Totally, 204 systemically healthy females at different phases of pregnancy underwent a full-mouth periodontal examination. Demographic characteristics, lifestyles, and systemic conditions were recorded. Referring to the CDC/AAP definition, the diagnostic performance of the AAP/EFP classification was evaluated by the area under the ROC curve (AUC) and statistical tests (e.g., Youden's index and kappa coefficient). Additionally, a modified scoring system of the FDI Periodontal Diseases Chairside Guide (FDI-CG) was formulated with the addition of pregnancy for testing accordingly. RESULTS: Overall, there were 22.1% of the participants in early phase of pregnancy (7-13 weeks) and 77.9% in late phase (34-36 weeks). The majority of them were below 35 years and non-smokers without gestational diabetes. Notably, 30.9% of subjects presented with Moderate/Severe periodontitis (CDC/AAP), and 35.8% with Stages II-IV periodontitis (AAP/EFP). Referring to the CDC/AAP definition, the AUC, Youden's index, and κ of the AAP/EFP classification were 0.979, 0.890, and 92.9%, respectively. The modified FDI-CG system improved the AUC (0.815), Youden's index (63.0%), and κ (0.544) with reference to the original one. CONCLUSIONS: This study shows that the AAP/EFP classification is in high agreement with the CDC/AAP definition among the pregnant women. The phases of pregnancy-integrated FDI scoring system may serve as a convenient screening tool for maternal periodontal diseases in general dental practice.

Types of clinical reasoning in a summative clerkship oral examination.

INTRODUCTION: Dual-process theory characterizes clinical reasoning (CR) as Type 1 (intuitive) and Type 2 (analytical) thinking. This study examined CR on a summative clinical clerkship structured clinical oral examination (SCOE). METHODS AND SUBJECTS: 511 clinical clerks at the University of Toronto underwent SCOEs. Type 1, Type 2, and Global CR performance were compared to other internal medicine clerkship assessments using descriptive statistics and Spearman correlations. RESULTS: Clinical clerks achieved mean marks >75% on the three clinical reasoning stations, on Type 1 and 2 CR tasks, and the overall SCOE. Performance on the SCOE CR stations correlated with each of the other clerkship assessments: written examination, inpatient, and ambulatory clinic assessments. The correlation of performance between Type 1 and Type 2 clinical reasoning tasks was statistically significant but weak (rs = 0.28). This suggests that defined measures of Type 1 and Type 2 reasoning were indeed assessing distinct constructs. CONCLUSION: Clinical clerks used both Type 1 and Type 2 reasoning with success. This study's characterization of Type 1 and Type 2 CR as separate domains, distinct from existing measures on the SCOE as well as the other clerkship assessments, can suggest a further addition to multimodal clerkship assessment.

Eight-year clinical evaluation of two types of resin composite in non-carious cervical lesions.

OBJECTIVES: In this clinical study, the 8-year clinical performances of a flowable resin composite was compared with that of a conventional resin composite. MATERIALS AND METHODS: Ninety non-carious cervical lesions (NCCLs) in 19 participants were involved in this trial. NCCLs were restored with a flowable composite (Clearfil Flow FX: FX, Kuraray Noritake, Japan) or a conventional resin composite (Clearfil AP-X: AP) in conjunction with a one-step self-etch adhesive (Clearfil S3 Bond). Each participant had both types of resin composite restorations that were randomly allocated. The restorations were evaluated at baseline and annually up to 8 years using modified USPHS criteria. The data were statistically analyzed using the Fisher's exact test, Kaplan-Meier method, and a multivariate Cox-regression with frailty models (p < 0.05). RESULTS: The 8-year participant recall rate was 95%. One hundred percent retention was recorded for AP, whereas four out of 46 restorations were lost for FX during the 8 years. The incidence of marginal staining increased over time regardless of the type of resin composite, showing 48% for AP and 57% for FX after 8 years. Wear of the resin composite occurred only for the flowable material and there was a significant difference between the types of resin composite (p = 0.024). Overall survival rates at 8 years for AP and FX were 98% and 82% respectively (p = 0.110). CONCLUSIONS: The flowable resin composite presented lower wear resistance and showed a lower survival rate compared with the conventional composite after eight years of clinical service. CLINICAL RELEVANCE: Flowable resin composites may show greater wear after long-term clinical service. TRIAL REGISTRATION NUMBER: UMIN000028745, Date of registration: August 19, 2017.

Internal structure and validity of the bedside oral examination tool in patients with brain injury at neurorehabilitation setting.

OBJECTIVES: To assess the internal structure and validity of the 'bedside oral examination' (BOE) instrument in individuals with acquired brain injury (ABI). METHODS: Ninety ABI individuals were examined using BOE in their first week of neurorehabilitation. BOE measures oral health within eight categories including: swallow, tongue, odour, teeth, lips, saliva, mucosa and gingiva. To assess the validity of BOE, full-mouth clinical examination (gold standard) was performed. The internal structure of BOE was assessed using exploratory and confirmatory factor analyses. To measure the validity, the BOE scores were dichotomised into excellent oral health and altered oral health. Sensitivity, specificity and area under the receiver operating characteristic (ROC) curve of the six/eight BOE items were compared with their related clinical oral examination tool. RESULTS: Overall, the patients had poor oral health irrespective of the oral examination tool used. Factor analyses indicated two factors within BOE: 'oral hygiene' (teeth, gingiva and mucosa) and 'orofacial health' (lips, swallow and saliva). BOE tongue and odour items loaded in neither factor. BOE items showed low validity since the highest area under the ROC curve was 0.60. Findings on the sensitivity value ranged from 35.0 to 74.2, while specificity from 44.4 to 83.3, depending on the item evaluated. CONCLUSION: Bedside oral examination does not seem to be an ideal 'single' outcome tool in a neurorehabilitation setting as it lacks validity. BOE evaluates oral health as two independent but correlated components and treat them separately indicating precision treatment depending on their oral health dysfunction. It is advisable to use BOE as a screening tool. However, it should be complimented by proper clinical examination before establishing a treatment plan for oral health in patients with ABI.

Computer-Aided Design and Manufacture of Intraoral Splints: A Potential Role in Cleft Care.

BACKGROUND: Nasoalveolar molding is a nonsurgical modality for the treatment of cleft lip and palate that uses an intraoral splint to align the palatal shelves. Repeated impressions are needed for splint modification, each carrying risk of airway obstruction. Computer-aided design and manufacturing (CAD/CAM) has the ability to simplify the process. As a precursor to CAD/CAM splint fabrication, a proof-of-concept study was conducted to compare three-dimensional splints printed from alginate impressions versus digital scans. We hypothesized that intraoral digital scanning would compare favorably to alginate impressions for palate registration and subsequent splint manufacture, with decreased production times. METHODS: Alginate and digital impressions were taken from 25 healthy teenage volunteers. Digital impressions were performed with a commercially available intraoral scanner. Plaster casts made from alginate impressions were converted to Standard Triangle Language files. Patient-specific matched scans were evaluated for total surface area with the concordance correlation coefficient. Acrylic palatal splints were three-dimensionally printed from inverse digital molds. Subjective appliance fit was assessed using a five-point scale. RESULTS: A total of 23 participants were included. Most subjects preferred digital impression acquisition. Impression methods showed moderate agreement (concordance correlation coefficient 0.93). Subjects rated splints from digital impressions as having a more precise fit (4.4 versus 3.9). The digital approach decreased impression phase time by over 10-fold and overall production time by 28%. CONCLUSIONS: CAD/CAM has evolved extensively over the past two decades and is now commonplace in medicine. However, its utility in cleft patients has not been fully realized. This pilot study demonstrated that CAD/CAM technologies may prove useful in patients requiring intraoral splints.

Adrenal incidentaloma as a novel independent predictive factor for periodontitis.

PURPOSE: There are no data regarding periodontal derangements in patients with adrenal incidentalomas (AI). We assessed the frequency and severity of periodontitis in patients with AI [non-functioning adrenal incidentaloma (NFAI) and possible autonomous cortisol secretion (ACS)] and compared with individuals with normal adrenal. METHODS: A cross-sectional study evaluated thirty-five individuals with AI and 26 controls. NFAI and possible ACS diagnosis was based on the current guidelines: NFAI [cortisol levels after 1 mg dexamethasone suppression test (1 mg-DST) ≤ 1.8 µg/dL (≤ 50 nmol/L)]; possible ACS [cortisol levels after 1 mg-DST 1.9-5.0 µg/dL (51-138 nmol/L)]. Sociodemographic data were collected, and a full-mouth periodontal evaluation was performed. RESULTS: There was no significant difference between groups regarding age, sex, income, ethnicity, education level, smoking, body mass index, dysglycemia, and arterial hypertension. Patients with AI exhibited worse periodontal conditions than controls for the following periodontal clinical parameters: mean percentage of probing pocket depth (PPD) and clinical attachment level (CAL) ≥ 5 mm (p < 0.001 and p = 0.006, respectively). Patients with NFAI and possible ACS showed higher gingival bleeding index (p = 0.014), bleeding on probing (p < 0.001), and CAL (p < 0.001) means compared to controls. The frequencies of periodontitis were 72.7% in patients with NFAI, 84.6% in possible ACS, and 30.8% in controls (p = 0.001). Periodontitis was more severe in patients with possible ACS than NFAI and controls. Patients with NFAI and possible ACS exhibited odds ratio for periodontitis of 4.9 (p = 0.016) and 8.6 (p = 0.02), respectively. CONCLUSION: Patients with AI have higher frequency and severity of periodontitis than controls. The presence of AI was an independent predictive factor for periodontitis.

Event-Based but Not Time-Based Prospective Memory Is Related to Oral Health in Late Adulthood.

BACKGROUND: Most evidence now indicates that cognitive function is related to poorer oral health in late adulthood, but that this relationship is not invariant across specific cognitive domains. Prospective memory (PM) is a core memory skill that refers to memory for future intentions and is known to be related to the formation of habits such as tooth flossing. However, the relationship between PM and oral health has been subject to only limited empirical study. OBJECTIVE: The two studies reported in this paper were designed to test whether PM is related to oral health in older adults of varying vulnerability status. METHODS: Study 1 sampled community-dwelling older adults (N = 172) living independently in the community; Study 2 sampled older adults living in a retirement village (N = 32). Participants in both studies were asked to complete a behavioural measure of PM, with their oral health indexed via self-report (Study 1) or an objective oral health exam (Study 2). RESULTS: In both studies, relationships emerged between event-based PM and oral health, with Study 2 showing that these relationships were specific to oral health measures of plaque and calculus. CONCLUSIONS: Older adults are particularly vulnerable to dental pathology, with important implications for their broader health and well-being. By showing that there is a relationship between oral health and a particular type of PM, this work will have potential implications for the development of more effective interventions focused on enhancing oral health outcomes in this group, such as those focused on strengthening habit formation.

Oral manifestations related to malaria: A systematic review.

OBJECTIVE: To generalize the oral manifestations related to malaria and discuss their clinical significance for health professionals. MATERIALS AND METHODS: The bibliographic databases of Public MEDLINE, Embase, Web of Science and Scopus were employed to retrieve publications online from January 1781 to August 2019. Original research articles, clinical trials, and case reports published in English were included. RESULTS: A small number of studies reported oral manifestations of malaria (n = 29), including gingival bleeding, glossitis, oral ulcer, abnormal oral pigmentation, pericoronitis, herpes labialis, herpes gingivostomatitis, bitter taste, sore throat, Burkitt lymphoma of the jaw, alveolar bone resorption, and enamel hypoplasia. CONCLUSION: Oral manifestations may be important indicators for identification of malaria. Dental and general professionals should pay more attention to oral manifestations in malaria cases, and guide them for specialized examination, diagnosis, and management.

Periodontitis and orofacial health-related systemic impairment in patients with brain injury: a factor analysis approach.

Aim: To investigate the association of periodontitis to orofacial health-related systemic impairment in patients with acquired brain injury (ABI).Methods: Ninety individuals with ABI were included. Full mouth periodontal examination was performed. Orofacial health-related 'motor' and 'cognitive' scores, dysphagia and feeding status, onset of pneumonia were retrieved from e-journal. Factor analysis dubbed periodontal data as 'moderate' and 'severe' periodontitis while orofacial health-related brain injury scores were dubbed into 'motor' and 'cognitive' domains. Association between periodontal findings and systemic impairments were analyzed using multivariable linear regression models.Results: Higher scores of 'moderate' periodontitis were significantly associated with lower scores of motor impairment (ß = -0.2), feeding tube dependency (ß = 0.2) and dysphagia (ß = 1.21), whereas higher scores of 'severe' periodontitis were associated with lower scores of cognition (ß = -0.2) and reduced dental visits (ß = -0.2). Both periodontal domains were significantly associated with aging (ß = 0.02) and onset of pneumonia (ß = 0.5-0.7).Conclusions: Robust association between 'moderate' periodontitis and motor impairment, feeding problems and dysphagia, reflects an acute clinical condition, demanding cross-disciplinary intervention. Periodontal examination can be an early indicator tool for systemic chronic conditions, as ABI and periodontitis share a common environmental, social and biological background. Periodontitis majorly affects ageing population and are prone to pneumonia, compromising rehabilitation plan.

A utilisation profile of publicly financed oral examinations in the Republic of Ireland.

AIM: To develop a utilisation profile for oral examinations performed under the remit of publicly financed dental services in the Republic of Ireland as a proxy for the overall level of service use. BASIC RESEARCH DESIGN: Collation of data from multiple administrative datasets for 2018, and generation of an age-specific oral examination utilisation profile. MAIN OUTCOME MEASURE: Age-specific oral examination rates per 1,000 population. RESULTS: A total of 1,163,399 publicly financed oral examinations were performed. Comparably low population-adjusted oral examination rates were observed in the 0-15, 16-24 and 75+ age cohorts. CONCLUSIONS: The National Oral Health Policy in Ireland aims to improve access to oral healthcare services across the life-course. Young children and older adults are highlighted as population subgroups with low levels of service eligibility and engagement, respectively. These results reinforce the need to focus on these age cohorts.
