Role of saliva in oral dryness,oral feel and oral malodour

Patients who believe they have oral malodour often have a dry mouth condition instead. Here we have examined its relation to oral malodour, real or perceived. A direct relationship between the thickness of the film of residual saliva on mucosal surfaces throughout the mouth and perception of a dry mouth was observed. On the hard palate, the thickness of this film proved to be diagnostic for a dry mouth and corresponded to lower resting saliva flow and pH levels (P< 0.001). Intra-muscular administration of the anti-sialogogue, Robinul, accurately produced the dry mouth condition. Using a sulphide monitor, loss of volatile sulphur compounds into mouth air progressively occurred as the mouth became drier. Mouth pH and Eh on the dorsum of the tongue correspondingly fell. Mouth breathing led to tongue and palate moisture loss thus enabling escape of malodour volatiles into mouth air. Measurement of oral dryness should make it possible to differentiate genuine malodour from dry mouth related pseudo-malodour subjects, and in turn, the latter from patients that are halitophobic. This should facilitate identification of such patients and avoid error in their clinical management.     

Evidence-based practice of oral pathology and oral medicine

Oral pathology is the specialty area of dentistry that deals with the diagnosis and management of oral diseases and more specifically, diseases other than dental caries, periodontal disease, restorative dentistry, and orthodontic therapy. Oral medicine represents the clinical arm of oral pathology and deals with diagnosis and treatment of soft-tissue lesions, whereas oral histopathology is the specialty area that focuses on the microscopic diagnosis of soft- and hard-tissue lesions of the head and neck area. The diagnosis and treatment of oral pathologic conditions is often based on empirical decision-making and many approaches to treatment have not been well-supported by clinicopathologic studies. The need for evidence-based, scientifically documented approaches to both diagnosis and treatment is eminent. Specific diagnostic criteria are lacking for many oral diseases, and therapeutic strategies have not been assessed by the gold standard of placebo-controlled, double-blind trials. Additionally, there are scientific data in the published literature that continue to be ignored by dental practitioners who manage patients with oral pathologic conditions. In this article, specific disease entities that are commonly managed by oral pathologists and oral medicine practitioners will be discussed with recommendations for future scientific studies that can serve as a framework for evidence-based diagnostic and therapeutic approaches.     

Detection of survivin mRNA in healthy oral mucosa, oral leucoplakia and oral cancer

Background:  Survivin is involved in modulation of cell death and cell division processes. Survivin expression in normal adult tissues has not been fully understood, although it is markedly lower than in cancer, where it is over-expressed.
Objective:  To investigate survivin expression in normal, potentially malignant and cancerous oral mucosa.
Methods:  We measured survivin mRNA levels by real-time RT-PCR in specimens of oral mucosa (15 from normal mucosa, 17 from potentially malignant lesions, 17 from neoplasms). Scores were compared using Kruskal–Wallis test and post hoc according to Conover. Chi-squared test was used for dichotomous data.
Results:  The median relative levels of survivin mRNA resulted six for normal mucosa, eight for potentially malignant lesions, 13 for cancers: differences among these three groups were statistically significant, as between cancer and potentially malignant lesions. Expression in normal mucosa and potentially lesions group showed no significant difference. Low, but not marginal expression of survivin in normal mucosa is a new finding, and it could be explained with the higher sensibility of our methods.
Conclusions:  Survivin expression in oral potentially malignant lesions might indicate a progressive deregulation of expression paralleling oncogenesis, particularly during the first stages of process, suggesting a putative predictive role for survivin.     

Influence of oral health and lifestyle on oral malodour

Objective: To assess the influence of oral health and lifestyle on the prevalence of oral malodour among university students. Materials and methods: Self‐administered questionnaires. Chi‐square test was used to detect any significant association between malodour and various variables. Results: 9% of males and 6% of females complained of malodour, while 36% of males and 31% of females did not complain of malodour. Nevertheless, 12% of the males and 6% of females were unable to decide. The highest percentage of respondents not complaining of malodour were non‐smokers (55%). A significant number of respondents were free from caries (48%), gingival disease (55%) and also were not complaining of malodour. Statistically, a significant association was found between malodour and gingival disease (p < 0.05) and between malodour and the use of a toothbrush on a daily basis (p < 0.001). Conclusions: The results highlight the influence of oral self‐care and lifestyle on malodour. Public awareness, diagnosis and treatment of malodour are primarily the responsibility of dentists. Malodour can have a distressing effect and the affected person may avoid socialising.     

Prevention of oral diseases and oral health promotion.

Research and activities, as promoted in 1989 and 1990, in oral disease prevention and health promotion are summarized. Significant syntheses of research findings have occurred, as a result of planning and workship activities, which will direct oral health promotion in the 1990s. Original research on established and new preventive therapies for dental caries, periodontal diseases, oral mucosal alterations, soft-tissue lesions, precancers and cancers, and trauma are reported, opportunities to prevent oral diseases or maintain oral health through changes in individual behaviors, professional orientation, and social and environmental changes are addressed.     

Effect of oral anticipatory guidance on oral health and oral hygiene practices in preschool children

Thirty children (6 to 18 months), enrolled in a dental program since birth, make up the intervention group. Control group consisted of thirty children who were of similar age and gender but had never been to a dental office. The presence of visible dental plaque and the performance of oral hygiene differed statistically between both groups. The dental program was effective in reducing visible dental plaque, and in establishing oral health habits among parents and young children.     

Relationship between chronic trauma of the oral mucosa,oral potentially malignant disorders and oral cancer

J Oral Pathol Med (2010) 39 : 513–517 Background: Oral cancer represents 2%–5% of all cancers, being one of the 10 most frequent ones. Apart from oral cancer risk factors already described in literature, such as tobacco and alcohol consumption, others emerging risk factors have been proposed, such as chronic irritation from dental factors. The aim of this work was to assess the influence of chronic trauma of the oral mucosa (CTOM) in patients with oral potentially malignant disorders (OPMD) and cancer. Methods: A retrospective study of 406 patients (both sexes; aged between 18 and 80 years; with OPMD and cancer) who attended the Department of Clinical Stomatology A of the National University of Cordoba was performed by non‐probabilistic sampling. The association of variables and outcome variable diagnosis, with levels control, OPMD, oral cancer, was evaluated by multinomial regression model. Results: Population under study was represented by 72% of control patients, 16% patients with OPMD and 11% of patients with oral cancer. It was observed a significant association between diagnosis and CTOM (P = 0.000), after adjustment of confounding factors (smoking and drinking habits, sex, cancer inheritance and denture use). Conclusions: Our results suggest that CTOM is, together with other factors, an important risk factor in patients with oral cancer diagnosis, but not for patients with OPMD.
