The nutritional effects of tooth loss.

In view of the high prevalence of edentulousness in developed countries, the evidence is reviewed for the effects of tooth loss on nutrition and health in the following categories of effects: mortality; food choice and nutrient intake; gastrointestinal irritation; digestion and nutrient absorption; nutritional status. The evidence indicates reduced consumption of meat, fresh fruit, and vegetables, and total energy resulting in lower Hb and vitamin C levels, increased gastrointestinal irritation and increased mortality from choking but no striking differences in digestion or nutritional status. However, most studies are not carefully controlled for other social and health factors.

Tooth loss and Helicobacter pylori seropositivity: the Newcastle Thousand Families Cohort Study at age 49-51 years.

BACKGROUND: Helicobacter pylori, one of the commonest chronic bacterial infections of humankind, is an important risk factor for gastric carcinoma. It has also been suggested to be present in dental plaque. This study investigated the potential link between the number of teeth lost and H. pylori seropositivity at age 50 years. METHODS: H. pylori seropositivity at age 50 years was investigated among 334 individuals born in Newcastle upon Tyne, United Kingdom, in May and June 1947 and related to the number of teeth lost, after adjusting for socioeconomic status. RESULTS: The unadjusted risk of being seropositive for H. pylori increased with increasing number of teeth lost (odds ratio per tooth 1.03, 95% confidence interval 1.01-1.06, p = .019). However, after adjustment for socioeconomic status at birth and at age 50 years, the relationship was no longer significant (p = .36). CONCLUSIONS: Our results, obtained using prospectively collected data, suggest that any relationship between poor oral health and seropositivity to H. pylori may be due to both tooth loss and H. pylori colonization being associated with socioeconomic status and related factors.

Associations between tooth loss and mortality patterns in the Glasgow Alumni Cohort.

OBJECTIVE: To use data from the Glasgow Alumni Cohort to investigate whether oral health in young adulthood is independently associated with later life cardiovascular disease (CVD) and cancer mortality. METHODS AND RESULTS: Of the original cohort (n = 15 322), 12 631 subjects were traced through the National Health Service Central Register. Of these, 9569 men and 2654 women were 30 years or younger at baseline. During up to 57 years of follow-up, 1432 deaths occurred among subjects with complete data, including 509 deaths from CVD and 549 from cancer. After adjusting for potential confounders, no substantial association was found between the number of missing teeth (as a continuous variable) and all-cause mortality (hazard ratio (HR) for each extra missing tooth = 1.01; 95% confidence interval (CI) 1.00 to 1.02), CVD mortality (HR = 1.01; 95% CI 0.99 to 1.03) or cancer mortality (HR = 1.00; 95% CI 0.98 to 1.02). When the number of missing teeth was treated as a categorical variable, there was evidence that students with nine or more missing teeth at baseline had an increased risk of CVD (HR = 1.35; 95% CI 1.03 to 1.77) compared with those with fewer than five missing teeth. When the number of missing teeth was transformed using fractional polynomials, there seemed to be a non-linear relation between missing teeth and CVD mortality. CONCLUSIONS: Although some evidence was found to support the relation between tooth loss and CVD mortality, causal mechanisms underlying this association remain uncertain.

Tooth loss and remaining occlusion in a Dutch population.

The aim of this study was to gain a better insight into the tooth-loss pattern in terms of frequency, location and impaired occlusion. The sample, stratified according to socio-economic class and age, consisted of 750 subjects. The investigation was done by questionnaire and clinical examination. The non-response was small (15%). With increasing age, more teeth were missing. In the lower socio-economic group more teeth were missing than in the higher socio-economic group. The percentage of totally edentulous persons as well as the percentage of persons with one edentulous jaw increased with age. Also, the percentage of antagonistic tooth contacts declined with increasing age. The following order was found in decreasing contacts: first premolar, second premolar, second molar and first molar. In all strata the percentage of antagonistic contacts in the premolar area was larger than in the molar area.

Caries experience, tooth loss and oral health-related behaviours among Bangladeshi women resident in West Yorkshire, UK.

Several studies have reported high levels of caries experience among young Muslim Asian children, but there has been little corresponding information on adult dental health or related health behaviours. This paper presents the results of a questionnaire together with clinical oral findings among first generation Bangladeshi women aged over 25 years. The majority chewed betel quid with tobacco, were of rural origin, used traditional oral hygiene practices and had never visited a dentist. Of the 247 examined, only one was edentulous. A very low level of caries experience was recorded, a mean DFT score of 1.87 at 25-34 years of age, with an average of 1.05 missing teeth. Coronal caries experience was found to be independent of oral hygiene methods, including the use of fluoride toothpaste, or the frequency of betel quid chewing. It was concluded that Bangladeshi adult women have considerably lower levels of caries experience and tooth loss than United Kingdom adults as represented in recent national surveys.

The effect of tooth loss on the TM-joint articular eminence inclination.

The inclination between the posterior wall of the articular eminence and the referential plane (Frankfurt line) was measured on 137 dry skull specimens (78 with complete dental arches and 59 edentulous). Both left and right joints were measured using direct craniometric method. The results were compared with respect to the loss of teeth, side and sex. A large range of measured values of the eminence inclination shows great individual differences, so that the mean values can have only orientational significance. The mean value of eminence inclination for all measured specimens was 61.9 angular degree. The difference between the two groups established upon dental status is very small and without any statistical significance (P > 0.05). The right joint shows a slightly steeper eminence inclination compared to the left one, but without any statistical significance (P > 0.05). Asymmetry between the right and left joint appears almost as a rule, while maximum measured differences reach up to 33 degrees, with mean absolute difference of 6.9 degrees. The group of edentulous specimens shows a greater symmetry and less differences between the left and right joint, which indicates that different bimechanical conditions in the joint, due to tooth loss might lead to remodellation of the articular eminence. The eminence inclination was significantly steeper in male specimens in all subgroups (P < 0.001), which confirms sexual dimorphism.

[Sequelae of tooth loss for the potential for chewing in the elderly].

The dentition is a part of the orofacial system. It has important functions such as speech and chewing. However the question is whether masticatory function declines when more loss of teeth occurs. In this article attention is given to the masticatory process and the masticatory performance in relation to complete or partial tooth loss and to the question to which requirements the dental prosthesis has to come up in relation to the food intake and the masticatory performance.

Early tooth loss due to cyclic neutropenia: long-term follow-up of one patient.

In young patients with abnormal loosening of teeth and periodontal breakdown, dental professionals should consider a wide range of etiological factors/diseases, analyze differential diagnoses, and make appropriate referrals. The long-term oral and dental follow-up of a female patient diagnosed in early infancy with cyclic neutropenia is reviewed, and recommendations for care are discussed.

Tooth loss in 1535 treated periodontal patients.

Of 1535 treated recall patients surveyed over an average time of 12.9 years since treatment was completed, 1371 had lost no teeth from periodontal disease. The total number of teeth lost was 444, with the average tooth loss for the 1535 patients being 0.29. In the three full arch splinted cases, the loss rate was 14.67 teeth per patient. Patients treated without any excisional or flap surgical procedures made up 26.5% of those surveyed, whereas 73.5% had required various surgical procedures. No attempt was made to compare different pocket therapy procedures. Although many patients developed recurrent periodontal problems during recall, only 15.9% of the 1535 patients required surgical retreatment. Teeth that were originally given a doubtful prognosis often were responsible for recurrent problems and sometimes required extraction.

The relationship of buccal pits to caries formation and tooth loss.

It is demonstrated that in mandibular molars there is a statistically significant tendency for teeth with buccal pits to be lost premortem more frequently than teeth without buccal pits. The mandibles of a large ossuary population (ca. 1600 A.D.) are examined with regard to buccal pitting, caries formation and premortem tooth loss. A log likelihood ratio test is used to test the relationship between age and frequency of buccal pits. A G-value of 20.84 (p less than 0.025) indicates that the frequency of pits is significantly higher among individuals under ca. 18 years. It is argued that caries formation is the mechanism through which the molars are lost, given high caries frequencies that approximate pitting frequencies in their distribution.

[Dental mutilation: rural workers' concepts of responsibility for tooth loss].

Brazilian oral hygiene institutions have promoted tooth extraction as a dental health practice. This article investigates the issue of dental loss within a rural drought area in the State of Bahia. Based on verbal information provided by local inhabitants, the author investigates dental extraction as perceived by the community, i.e., as a commonplace fact. The main goal is to analyze both representations of the oral cavity based on individual experiences and their associations with oral care practices, derived from the social reality in which they are immersed. The author considers the issues of both individual responsibility and that of government agencies and dentists.

Prevalence of total tooth loss, dental caries, and periodontal disease in Mexican-American adults: results from the southwestern HHANES.

The Southwestern portion of the Hispanic Health and Nutrition Examination Survey (HHANES) was conducted by the National Center for Health Statistics (NCHS) in 1982 and 1983. The survey population was Mexican-Americans residing in five Southwestern states. This report presents data on the prevalence of total tooth loss, dental caries, and periodontal diseases in 3860 Mexican-American adults aged from 18 to 74. Results show that 4.3% of this group was edentulous. Among the dentate, Mexican-Americans had lower overall DMF scores but higher numbers of untreated decayed teeth than did residents of the same region seen in the NHANES I survey in 1971-1974. Caries of the smooth surfaces in both posterior and anterior teeth was more pronounced in the older than in the younger age groups. Mexican-Americans had more gingivitis but fewer periodontal pockets than did the general population in the Western states during NHANES I. The caries pattern in the Mexican-Americans suggests that caries among adults may remain a problem in the future, with the possibility of increased involvement with the aging, although modest, of smooth tooth surfaces.

Tooth loss, prosthetics and dental treatment habits in a group of Swedish men.

Dental history, dental status, the need for prosthetic treatment and dental treatment habits were studied in 389 men aged 21--54 years. The men were selected from a group undergoing military refresher training in the south of Sweden. One percent of the men were toothless. About 3% had full dentures in one or both jaws and an equal percentage had partial dentures. About 3% of the men had bridges in the maxilla and 2% in the mandible. Tooth loss was greatest in the mandibular molar segment, followed by the maxillary molar segment. By means of an index for dental status about 8% of the men were judged to be in great need of prosthetic treatment for aesthetic reasons and/or to improve occlusion. Age, place of birth, educational level and smoking habits were among the factors which seemed to be related to dental status. Seventy percent of the men reported that they went to the dentist once a year, while about 10% seemed rarely or never to seek dental treatment. Dental treatment habits were correlated to place of birth, number of brothers and sisters, edentulousness and the need for prosthetic treatment, among other factors.

Perceptions of tooth loss and periodontal problems in an independent elderly population: content-analysis of interview discourse.

Oral health/illness and surrounding socio-demographic and behavioral phenomena are poorly documented in the Mexican elderly. To establish the rationales explaining oral health/illness and tailor a Health Promotion intervention (1995-1997) accordingly, an interview nested in a questionnaire was done at baseline, with the recording of 228 interviews transcribed verbatim. Every transcript was subsequently assessed by content-analysis. Results showed that lack of oral hygiene, inadequate calcium intake and old age were the most common explanations of tooth-loss. Only a few factors were felt to be under control: the same state of relative adaptation that characterized people affected by gum problems. The themes that explained them were lack of oral hygiene, and (non-specific) infections. When interviewees evaluated the impact of good oral health on their lives, many made evaluations pertaining to quality of life, adequate function, and an attractive appearance generally.

The relative importance of tooth loss and denture wearing in Swedish adults.

Having natural teeth is a matter of varying importance according to the priorities given to dental health status, compliance with recommendations and demand for dental care. The aim of this study was to assess the relative adjustment needed when one or more teeth are lost and when dentures are provided compared with other life events. The study was conducted as a mailed questionnaire to a sample of 311 20-70 year old subjects in the community of Jönköping. Seventy-five per cent of the sample, with a mean age of 43.2 years, responded. The Social Readjustment Rating Questionnaire, comprising 46 life events, was supplemented with two events concerning tooth loss and denture-wearing. The answers were given on a graphic rating scale with end points 'not difficult at all' and 'more difficult than anything' and coded by values 0 to 20. After calculation of mean values, the questions were rank ordered; the item with the highest mean was given the highest rank. 'Losing one or more teeth' was ranked 28.5 (means = 10.7) and 'getting dentures' 33 (means = 12.0) of the 48 life events investigated. This suggests that a majority of respondents perceived losing teeth and being provided with dentures as more important in terms of adjustment than events such as 'marriage', 'retirement' and 'changing work'. No significant differences in relation to age and sex were found.

Smoking habits and tooth loss in Swedish women.

A longitudinal population study of 1462 women, aged 38-60, was started in Gothenburg, Sweden, in 1968-69. In univariate analysis of the results from 1968-69, smokers were found to have a significantly lower number of remaining teeth than non-smokers had. The differences between smokers and non-smokers with respect to edentulousness and number of remaining teeth was further accentuated 12 yr later. The mean number of teeth lost during the 12-yr follow-up period was 3.5 among smokers and 2.1 among non-smokers, i.e. 67% higher among smokers than among non-smokers. The associations were independent of age, education, socio-economic group, marital status, frequency of toothbrushing, and frequency of visits to a dentist. It is concluded that smoking seems to play an important role as far as tooth loss is concerned.

Tooth loss and dental caries in Dutch adults.

As part of a nationwide dental survey in 1986 a caries study was executed in 3526 adults, aged 15-74 yr, living in 40 residential areas in The Netherlands. Marked differences were found between the social classes distinguished (more edentates in the lower classes) and between the different regions. It is supposed that these differences reflect the lack of dental manpower in the past.

Number of teeth and tooth loss of former dental school patients. Follow-up study after 10-17 years.

Persons (n = 431) who had received endodontic and other treatment at the School of Dentistry in Bergen in the 1960s were invited to attend an examination in 1980, some 10-17 years after their first course of treatment. The age range initially had been 16-55 years. The attendance rate was 55% (149 women and 89 men) and was higher for the older age groups. Data from pre- and post-treatment records were added to the information obtained in 1980. Those who attended in 1980 had had 22.8 teeth at the initial examination and 21.2 teeth after their first course of treatment in the 1960s. In 1980 they had 19.3 teeth. About 20% of the persons had the same number of teeth at all three examinations, and 43% had not lost teeth after completing treatment at the school. Molars and maxillary teeth were most likely to have been extracted. This was also the case for teeth lost during the first course of treatment. Some 4% of the individuals had become edentulous. Conventional dental treatment had not prevented further tooth loss; the number of remaining teeth within each age group was about the same in 1980 as in the 1960s.
