Salivary defence factor concentrations in relation to oral and general parameters in HIV positive patients.

The objective of this study was to determine the relationships between saliva protein concentrations, oral mucosal lesions, and systemic parameters in HIV positive patients and controls. Twenty-three control volunteers and 58 HIV-antibody positive patients received a complete oral examination and medical evaluation. In saliva and serum samples, protein concentrations were recorded by a nephelometric method. The systemic parameters assessed were CD4+ cell count, CDC stages and antiretroviral therapy. Oral mucosal lesion prevalence was higher among subjects with lower CD4+ counts. Considering the protein profile, correlations were recorded between saliva and serum protein concentration for IgA, haptoglobin and alpha1-proteinase inhibitor. Using assays of immune and non-immune saliva defence factors, we found that the evolution of cellular immuno-suppression during HIV infection was correlated to oral mucosal disease, showing a relationship between local and general systems.

A national epidemiological survey of oral mucosal lesions in Malaysia.

The prevalence of oral mucosal lesions in Malaysia was determined by examining a representative sample of 11,707 subjects aged 25 years and above throughout the 14 states over a period of 5 months during 1993/1994. A two-stage stratified random sampling was undertaken. A predetermined number of enumeration blocks, the smallest population unit in the census publication, was selected from each state. With the selected enumeration block, a systematic sample of living quarters was chosen with a random start. The survey instrument included a questionnaire on sociodemographic characteristics and a clinical examination. The clinical examination was carried out by 16 specially trained dental public health officers and the diagnosis calibrated with a final concordance rate of 92%. The age in the sample ranged from 25 to 115 years with a mean of 44.5+/-14.0. The sample comprised 40.2% males and 59.8% females; 55.8% were Malays, 29.4% Chinese, 10.0% Indians and 1.2% other ethnic groups. Oral mucosal lesions were detected in 1131 (9.7%) subjects, 5 (0.04%) had oral cancer, 165 (1.4%) had lesions or conditions that may be precancerous (leukoplakia, erythroplakia, submucous fibrosis and lichen planus) and 187 (1.6%) had betel chewer's mucosa. The prevalence of oral precancer was highest amongst Indians (4.0%) and other Bumiputras (the indigenous people of Sabah and Sarawak) (2.5%) while the lowest prevalence was amongst the Chinese (0.5%).

Oral mucosal lesions and oral hygiene habits in the home‐living elderly

summary A large epidemiological health investigation, the Helsinki Ageing Study (HAS), was performed in 1989–1991 in Helsinki, Finland. We report here the prevalence of oral mucosal lesions in 338 76‐, 81‐ and 86‐year‐old home‐living elderly people, who completed the oral health investigation at the Institute of Dentistry, University of Helsinki. One or more lesions were found in 128 subjects (38%). Fifty‐one per cent of the edentulous complete‐denture wearers and 31% of the elderly with some natural teeth had mucosal lesions. The most common finding was inflammation under the denture, which occurred alone or combined with other lesions in 25% of the denture wearers. The three most common mucosal changes not related to denture wearing were coated changes of the tongue (7%), angular cheilitis (6%) and varicose veins under the tongue (4%). No differences were found in the number of mucosal lesions among the three age groups. Angular cheilitis and inflammation under removable dentures were more frequent in women than in men. However, no other differences were found in the presence of mucosal lesions between sexes. The total number of mucosal lesions correlated positively with the number of medications used daily. Ninety‐six per cent of the subjects with complete dentures, and 98% of those with some natural teeth reported cleaning their dentures at least once a day. Of the denture wearers, 88% reported cleaning their oral mucosa also, as part of their oral hygiene routine. The presence of mucosal lesions was related to self‐reported cleaning of the denture‐bearing mucosa. However, no association was observed between cleaning frequency and presence of mucosal changes.

Head and neck cancer screening among 4611 tobacco users older than forty years.

We implemented screening for squamous cell carcinomas of the oral cavity, pharynx, and larynx with symptom assessment and systematic inspection of the oral mucosa by primary care practitioners at health care sites serving inner-city residents of Boston; 4611 tobacco users older than 40 years were screened, and 313 with specific criteria were referred to otolaryngology for diagnostic evaluations. In these screened patients, the prevalence of oral mucosal lesions was almost 13% and prevalence of persistent hoarseness was more than 11%. Although the identification of these cancers was rare (nearly 3%), abnormal findings were seen in more than 70% of referred patients. These clinical and histologic diagnoses are described. We have documented the range of pathologic conditions in high-risk patients screened for upper aerodigestive tract malignancy.

An epidemiological survey of oral mucosal lesions among elderly Malaysians.

A house to house random survey on elderly subjects was undertaken in the District of Klang in Malaysia. The objective of this study was to investigate the prevalence of oral mucosal lesions (OML) among the elderly in this area. The primary units in the sampling frame were the Enumeration Blocks (EBs) as defined under the population census. All households of the selected EBs were considered as sampling units and members aged 60 and above were considered as respondents. There was a slight preponderance of females, with the Malays comprising the majority of the subjects. Of the 486 respondents, mean aged 69.1 +/- 7.3 yr, 111 had at least one oral mucosal lesion, a prevalence of 22.8%. A total of 145 lesions were detected. The prevalence of OML was highest among Indians and least among the Chinese. The most common finding was tongue lesions, recording a prevalence of 10.7%, followed by oral pigmentation (4.9%) and white lesions (4.3%). Denture related lesions were comparatively low at 2.5%. Two cases of oral cancer if representative would give a relatively high prevalence of 0.4%.

Oral mucosal lesions in 65-74-year-old Hong Kong Chinese.

There have been no reported surveys of oral mucosal lesions among the elderly in Asian countries. Therefore, the purpose of this study was to determine the prevalence of oral mucosal lesions among 65-74-yr-old, community-dwelling elderly Chinese in Hong Kong and to determine the prevalence of lesions in denture wearers, tobacco smokers, and alcohol drinkers. A total of 537 noninstitutionalized 65-74-yr-olds were interviewed and clinically examined in an oral health survey conducted in 1991. In the survey, the elderly underwent a systematic examination of their oral mucosa by one of the three examiners with the aid of an overhead light. The examiners were trained and calibrated before and during the survey, and a specially prepared colour atlas of oral mucosal lesions was used for lesion recognition. No mucosal lesions were detected in 64% of the elderly. In the 193 elderly subjects with lesions, 80% exhibited only one lesion. There was no difference in prevalence between men and women. The more common lesions, each being found in 5-7% of the elderly, were lingual varicosities, frictional keratosis on the buccal mucosa, denture stomatitis on the palatal mucosa, and denture-induced hyperplasia in the maxillary and mandibular buccal sulcus. Denture wearers had a higher prevalence of lesions (40%) than nonwearers (32%). There was no difference in the prevalence or number of oral mucosal lesions between those defined as users of tobacco and alcohol and those defined as nonusers in this study. No confirmed oral malignancies were found.

Evaluation of an oral health service for nursing home residents

The purpose of this study was to evaluate a comprehensive, on-site, oral health care program for nursing home residents. Before and after a 1-year evaluation period the elderly residents in the nursing home (NH-1) were interviewed and examined clinically. A comparable control group comprising the elderly residents in another nursing home (NH-2) were also interviewed and clinically examined before and after a 1-year period. The main objectives of the program were to increase the utilization of the dental care system, to meet the need for immediate attention, to improve oral hygiene, to reduce the prevalence of oral mucosal lesions, gingivitis, and untreated decay, and to meet the realistic prosthodontic treatment need. All the elderly residents accepted a yearly examination by a dentist, and 50% were treated in NH-1 during the evaluation period, compared with 16% in NH-2. The need for immediate attention was reduced by 56% in NH-1 and had increased by 20% in NH-2. Whether the activities in NH-2 qualify as an oral health program with on-site examinations and referral for treatment outside the institution is discussed. The annual cost per resident during the evaluation period was a little more in NH-2 than in NH-1. The conclusion is that oral health improved during the observation period in both nursing homes. The rate of participation and the improvement in oral health was most evident in NH-1.

Low prevalence of oral mucosal lesions in HIV-1 seropositive African women.

In Nairobi (Kenya) 334 women prostitutes of whom 80.5% were HIV-1 positive, were examined for oral mucosal lesions; 15.6% of seropositive, and 4.6% of seronegative, women had oral mucosal lesions, predominantly oral candidiasis. In the seropositives, 8.6% had erythematous, 1.1% had hyperplastic candidiasis, and 0.4% had hairly leukoplakia as the only oral lesions; 0.4% had a combination of erythematous and hyperplastic candidiasis, and 1.5% had combinations of pseudomembranous and erythematous candidiasis in the presence of hairly leukoplakia. Of the 211 seropositive women for whom we knew the first date on which a positive serologic test was obtained, the likelihood of developing an oral mucosal lesion was found to be dependent on the duration of seropositivity. The low incidence of oral mucosal lesions in this population may be due to the relatively recent acquisition of HIV-1 infection.

The Prevalence of Oral Mucosal Lesions in the Elderly in a Surgical Biopsy Population: A Retrospective Analysis of 4042 Cases1

A series of over 4000 oral mucosal biopsy cases was examined in two age groups, elderly (greater than or equal to 65 years) and non-elderly, and allocated between seven diagnostic categories. The data were analysed against the know age-sex distribution of the general population of the Mersey Region from which the oral biopsy cases had been drawn. The distribution of diagnostic categories was significantly different between the two age groups. For all diagnostic categories except mucosal cysts (malignant and premalignant disease; benign keratoses; denture-induced hyperplasia; benign proliferative lesions; lichen planus; and miscellaneous diseases) the age-corrected prevalence was higher in elderly than non-elderly with the greatest difference occurring in malignant/premalignant diseases (5.5-fold higher prevalence in the elderly). The results suggested that in the Mersey Regional population the prevalence of oral mucosal disease, of a type and severity to warrant surgical removal of tissue, was 47% higher in the elderly than the non-elderly. These results strongly support the notion that age exerts an important influence on the prevalence and pattern of oral mucosal disease in man.

Association between cigarette smoking and prevalence of oral mucosal lesions among Malaysian army personnel.

The association between cigarette smoking and the prevalence of oral mucosal lesions was examined in 495 Malaysian army personnel. No associations between cigarette smoking and recurrent aphthous ulcerations, pre-leukoplakia and frictional keratosis could be obtained in this study. Positive associations were found between cigarette smoking and leukoedema as well as denture stomatitis. There was a negative association between cigarette smoking and the presence of coated tongue.

Oral mucosal lesions in patients with acute leukemia and related disorders during cytotoxic therapy.

This study reports the presence of oral mucosal lesions in 26 patients with acute leukemia during the initial weeks of treatment (induction period). For comparison, three groups of patients without malignant disorders (acute disorders, long-term hospitalization, antibiotic treatment) were included. All patients were treated at the University Hospital of Umeå, Sweden. During the period of hospitalization hemorrhages were seen in 14 of the 26 patients with leukemia. No specific location was found. A correlation between presence of hemorrhages and low platelet counts was noted. Eighteen of the patients revealed ulcerations during the period. Ulcerations were predominantly found on the buccal mucosa, the lips, and the tongue. A tendency to an increase in the number and severity of ulcers was noted during the period of induction therapy. A correlation between presence of ulcers and low granulocyte counts was found. Candidiasis-like changes were seen in eight of the patients with leukemia. Compared with the patients with leukemia the patients in the reference groups showed a low prevalence of oral mucosal lesions.

Oral mucosal lesions among institutionalized elderly in Denmark.

The purpose of the study was to determine the prevalence of oral mucosal lesions among institutionalized elderly. The study population comprised 486 elderly from eight nursing homes, and 199 elderly from five hospital long-term care facilities in the eastern part of Denmark. Approximately half of the subjects exhibited one or more pathologic conditions of the oral mucosa. Denture related traumatic ulcerations were found in 3.9% of the nursing home residents, compared to 8.3% among the elderly in hospital long-term care. The most prevalent finding was denture stomatitis, which was manifest in about one third of the elderly. The prevalence was strongly influenced by the denture hygiene; 54% of the elderly with poor denture hygiene suffered from denture stomatitis, as compared to only 7% of those with clean dentures. The prevalence of denture stomatitis was also related to the usage of dentures at night and to the age of the dentures. The prevalence decreased significantly with increasing age, although the oldest age group did not have better denture hygiene, or more favorable wearing habits. It did not appear that sex, type of residency, degree of urbanization, denture conditions, or the use of anticholinergic drugs influenced the prevalence of denture stomatitis. The prevalence and severity of the disease can probably be reduced if the denture hygiene is improved and if the elderly only use their dentures during the daytime.(ABSTRACT TRUNCATED AT 250 WORDS)

The prevalence of oral mucosal lesions in an elderly population

In a population of 629, 145 elderly subjects had at least one mucosal lesion; 27% of denture wearers had a denture-related lesion. Lesions were found most commonly on the palate, followed by the lips. Increasing age was the only significant factor in the risk of soft tissue enlargement.

Prevalence of oral mucosal lesions associated with wearing removable dentures in Finnish adults.

Of a representative sample of 8000 persons aged 30 and over living in Finland, 3875 users of removable dentures were examined. The condition of the oral mucosa was recorded during clinical examinations. The prevalence of oral mucosal lesions associated with removable dentures was analyzed according to age, sex, place of residence, geographical region of living, and type and location of prosthesis. Lesions were found in about 50% of the denture wearers. Women were affected more often than men. The prevalence of lesions decreased with age and differed slightly according to region of living and place of residence. Compared with the wearing of partial dentures, wearing complete dentures increased the risk of lesions. Only one of the 72 denture users who wore a denture with metallic base plate had oral mucosal lesions associated with wearing a denture.
