Prevalence Of Periodontal Pockets Research Articles

Oral hygiene and periodontal condition of 12- and 15-year-old Greek adolescents. Socio-behavioural risk indicators, self- rated oral health and changes in 10 years.

To investigate oral hygiene and periodontal status of 12- and 15-year-old Greek adolescents in relation to socio- demographic and behavioural indicators and identify national trends. In a stratified cluster sample of 2,478 participants, the Simplified Debris Index (DI-S) and the Community Periodontal Index (CPI) were calculated. Socio- demographic/behavioural data were collected through structured questionnaires. Multivariate ordinary regression examined the effect of socio-behavioural indicators on oral hygiene and periodontal conditions. 51.7% of the 12-year-olds and 56.9% of the 15- year-olds had fair and good oral hygiene, respectively. Approximately 30% of the adolescents had healthy periodontium. Bleeding on probing was detected in 23.6% and 21.6% of the 12- and the 15-year-olds, accordingly. Calculus was found in 46.2% and 44.3% of the 12- and the 15-year-old groups, correspondingly. The prevalence of periodontal pockets ?4mm was 3.2%. Significantly higher DI-S scores were found among 12-year-olds who were males, had lower educated mothers or did not use dental floss and among adolescents who brushed their teeth <twice/day. Inferior periodontal status was found among 15-year-olds who were males, 12-year- olds with lower educated mothers, who did not brush or brushed infrequently, and among subjects who did not floss. Poor self-rated oral health was significantly related to adverse oral hygiene and periodontal health outcomes. Oral hygiene and periodontal status of Greek adolescents improved moderately in ten years. Periodontal health promotion strategies should target vulnerable sub- groups of adolescents to reduce future periodontal burden. Self-rated oral health may be useful for identifying unmet periodontal treatment needs.

Periodontitis, tooth loss and cognitive functions among older adults.

This study aims to evaluate the potential association between periodontitis, the number of teeth and cognitive functions in a cohort of older adults in Sweden. In total, 775 individuals from 60 to 99years of age were selected for the study. A clinical and radiographic examination was performed. The number of teeth and prevalence of periodontal pockets and bone loss was calculated and categorised. Cognitive functions were assessed using the Mini-Mental State Examination (MMSE) and clock test. The education level was obtained from a questionnaire. Data were analysed using chi-square tests and multivariate logistic regression. Age and gender were associated with the prevalence of bone loss. Age and education were associated with lower number of teeth. Gender was also associated with the presence of pockets. The multivariate logistic regression analysis demonstrated a statistically significant association between prevalence of bone loss, the number of teeth and the outcome on MMSE test. This association remained even after adjustment for age, education and gender. Tooth loss was also associated with lower outcome on clock test. Presence of periodontal pockets ≥ 5mm was not associated with cognitive test outcome. A history of periodontitis and tooth loss may be of importance for cognitive functions among older adults. Diseases with and inflammatory profile may have an impact on cognitive decline.

Comparative evaluation of oral health status of chronic kidney disease (CKD) patients in various stages and healthy controls

To compare caries, oral hygiene and periodontal status of chronic kidney disease (CKD) patients in different stages and healthy controls. Seventy-four patients diagnosed with CKD and 150 healthy age and sex matched controls were recruited from General Hospital of Udaipur, India. Each subject was examined for caries by decayed, missing and filled teeth (DMFT) index, oral hygiene by simplified oral hygiene index (OHI-S) while gingival and periodontal status were assessed by Loe and Silness gingival and Community Periodontal Index, respectively. All the examinations were conducted by a single investigator. Study subjects presented significantly lower caries experience than the control group but no significant difference was observed among the subjects in various stages of CKD. The mean gingival index score for study group (1.88) was more than twice to that of control subjects (0.92). Stage of kidney disease influenced the gingival and oral hygiene status which decreased as the stage progressed. The overall prevalence of periodontal pockets (70.3%) in diseased subjects was significantly higher than controls (18.9%). More than three quarters (78.9%) of the patients with stage 5 CKD exhibited deep periodontal pockets. Oral hygiene, gingival, and periodontal status decreased as the stage of CKD increased and was worse among study subjects that the controls. Dental caries did not differ significantly with the stage of the renal disease but was significantly lower among study subjects than the controls.

Tooth loss in periodontally treated patients. A long‐term study of periodontal disease and root caries

To study periodontal conditions, root caries, number of lost teeth and causes for tooth loss during 11-14years after active periodontal treatment. Sixty-four patients participated in the follow-up study. Reasons for tooth loss were identified through previous case books, radiographs and clinical photos. To identify factors contributing to tooth loss, a logistic multilevel regression analysis was used. The number of lost teeth was 211. The main reason was periodontal disease (n=153). Due to root caries and endodontic complications, 28 and 17 teeth, respectively, were lost. Thirteen teeth were lost for other reasons. The number of teeth (p=0.05) and prevalence of probing pocket depths, 4-6mm (p=0.01) at baseline, smoking (p=0.01) and the number of visits at dental hygienists (p=0.03) during maintenance, significantly contributed to explain the variation in tooth loss. Previously treated patients at a specialist clinic for periodontology continued to lose teeth in spite of maintenance treatments at general practitioners and dental hygienists. The main reason for tooth loss was periodontal disease. Tooth loss was significantly more prevalent among smokers than non-smokers. Tooth-related risk factors were smoking, low numbers of teeth and prevalence of periodontal pockets, 4-6mm.

A Survey of Equine Oral Pathology

Dental abnormalities in horses can lead to weight-loss, poor performance, pain, behavioral abnormalities, and illness. Despite this impact, the occurrence and type of dental disease in horse populations is infrequently reported in veterinary medicine. The purpose of this cross-sectional survey of horses presented for slaughter at a processing plant in Western Canada was to measure the prevalence of equine oral abnormalities, examine associations between the most common abnormalities, and consider the relationship between the age of horse and types of abnormalities observed. The horses used in this research consisted of a variety of ages, breeds, body conditions, and origins. Horses ranged in age from 18-months to 30-years (median = 11-years). The most common oral pathologies included sharp edges, buccal abrasions, calculus, lingual ulcers, gingival recession, periodontal pockets, ramps, and waves. Several types of pathology were strongly associated with other dental disorders. The prevalence of periodontal pockets, gingival recession, and waves was highest in older horses.

Assessment of periodontal knowledge and periodontal status of an adult population in Jordan

The aim of this study was to assess periodontal knowledge and periodontal status in 20-60-year-old adult population in northern Jordan. A convenient sample consisting of 722 adults was included in this study. A questionnaire incorporating items related to socio-demographic and periodontal knowledge questions was completed before clinical examination, using the Community Periodontal Index of Treatment Needs (CPITN). The results showed that the proportions of subjects who reported bleeding gums, gums' irritation, rough tooth surface and gum disease decreased steadily with age, there is an evident linear trend with high statistical significant difference among various age groups (P < 0.001). Furthermore, the proportions of subjects who answered correctly the periodontal knowledge questions related to plaque definition and its role in disease aetiology and prevention, decreased with age, with a high significant difference for all knowledge questions (P < 0.001). The prevalence of subjects with healthy periodontium (score 0) decreased with age, being 41.1% among 20-29-year-old group and 11.1% in 50-60-year-old group. Similar trend was seen for bleeding on probing (score 1) whilst calculus deposit (score 2) was the major problem in all age groups over 29 years. The prevalence of periodontal pockets was relatively low, with a range of 4.5-18.6% for shallow pockets (score 3) and 2.9-11.1% for deep pockets in younger and older age groups, respectively. Younger age group had more healthy sextants than older age groups. In addition, sextants with bleeding on probing were highest in 20-29-year-old age group (1.8) compared with that in 50-60-year-old age group (0.60) whilst those with calculus deposits varied slightly among different age groups (1.50-1.65). Sextants affected by shallow or deep pockets increased steadily with age. Such a finding was also noted in excluded sextants, with an increase from 0.15 at 20-29 year-old group to 0.94 at the age of 50-60 years. It is concluded that health knowledge and status related to periodontal disease is still poor in northern Jordan. Therefore, dental health education provision is necessary to improve oral health knowledge and conditions among population in general and among older population in particular.

Gingival and periodontal conditions associated with socioeconomic factors

To assess the prevalence of gingival bleeding, calculus and periodontal pockets among 18-year-old males. In addition, to verify whether these conditions are associated with years of education and family income. A cross sectional survey was carried out. A representative sample of 18-year-old males living in Florianópolis, Brazil, was selected from the Brazilian Army applicant list. Clinical and socioeconomic data were collected through dental examinations and interviews, respectively. Socioeconomic data included the subjects and their parents' years of education, and family income. A single dentist carried out the dental examinations looking for gingival bleedings after probing, calculus and shallow and deep periodontal pockets (3.5 mm to 5.5 mm and 5.5 mm and over). The associations between periodontal conditions and socioeconomic variables were analyzed using the qui-square test. A total of 286 people participated in the study. Intra-examiner agreement was high. All kappa values were above 0.7. The prevalence of gingival bleeding, calculus, shallow and deep periodontal pockets were 86%, 50.7%, 7.7% and 0.3% respectively. There were associations between gingival bleeding and all socioeconomic variables (p<0.001). Calculus were associated with the subject's and their father's low educational level (p<0.05) and with their mother's low educational level (p<0.01). Periodontal pockets were associated with their father's low educational level (p<0.05). The prevalence of periodontal pockets was very low, while gingival bleeding and calculus were high. General periodontal health of the studied population was good.

Prevalence of periodontal conditions among public‐funded dental patients in Australia

The aims of this study were to describe periodontal health status by gender, type of care, geographic location and age and to investigate associations of these factors with tooth loss. In 1995-96, state and territory dental services surveyed a random sample of 6,109 public-funded patients. Dentists recorded oral health status at the initial visit of a course of care, using written instructions but without formal calibration. Periodontal status was assessed using the community periodontal index of treatment needs. Prevalence of periodontal conditions among dentate patients was higher among older, male, emergency and urban patients (chi2; p<0.05). Age-specific edentulism was lower for male, emergency and urban patients (chi2; p<0.05). Numbers of missing teeth were lower for younger, non-emergency and urban patients (Anova; p<0.05). Prevalence of periodontal pockets 6mm or more was associated with gender, type of care, geographic location, age and number of missing teeth (logistic regression; p<0.05). Prevalence of severe periodontal conditions was lower in 1995-96 compared with public-funded patients in 1984 and 1992-93, but prevalence of periodontal health remained lower than the general population in 1987-88. A survivor effect may result in lower recording of severe periodontal conditions among subgroups with higher tooth loss.

Changes in the prevalence of residual pockets and tooth loss in treated periodontal patients during a supportive maintenance care program.

Bleeding on probing and the presence of deep periodontal pockets are considered to be the best site-specific indicators for periodontal disease progression during the maintenance phase of periodontal therapy. A major emphasis of supportive periodontal care (SPC) programs, therefore, has been the control of bleeding pockets. This investigation retrospectively evaluated the changes in the prevalence of bleeding on probing, periodontal pockets, bleeding periodontal pockets and the prevalence of tooth loss in a random sample of 273 periodontal patients participating in a supportive maintenance care program at a University Clinic. During an observation period of 67+/-46 months (range 5 months to 23 years), the overall incidence of all causes of tooth mortality was 0.23+/-0.49 teeth per patient per year of observation. 56% of subjects, however, did not experience any tooth loss, while less than 10% of patients lost more than 3 teeth. Thus, participation in the SPC program was effective in preventing tooth loss in the majority of patients. During the SPC period, however, a significant increase in the prevalence of periodontal pockets, and of bleeding on probing positive periodontal pockets, in particular, was observed. At completion of active periodontal therapy, 56.4% of patients were free from bleeding pockets. This decreased to a mere 13.6% at the latest SPC evaluation. The observed increases in the number of bleeding pockets was significantly associated with: longer times since completion of active periodontal therapy, more advanced periodontal diagnosis, higher %s of bleeding sites in the dentition, cigarette smoking, lack of inclusion of periodontal surgery in the active treatment phase, tooth loss, and the response to the active phase of periodontal treatment. The data presented in the paper indicate that the observed increase in the prevalence of bleeding pockets and tooth loss was not homogeneously distributed in the studied SPC population. Rather, high risk groups of individuals could be identified. It is suggested that better knowledge of risk indicators may lead to improved and more efficient risk management efforts during periodontal maintenance care.

Occurrence of periodontal pockets and oral soft tissue lesions in relation to sulfuric acid fumes in the working environment

The effect of inorganic acid fumes from the working environment on the occurrence of periodontal pockets and soft oral tissues was investigated in a cross-sectional, blind study. A sample of 186 workers was drawn from 4 factories. Of the 170 participants, 82 were working in departments containing acid fumes, and 88 controls had never worked under such conditions. Of the workers exposed to acid fumes 36.9% and of the controls 30.9% had periodontal pockets. The presence of periodontal pockets increased with age significantly more among the acid-exposed workers than among the controls (p less than 0.0001). Oral mucous membrane lesions were observed among 23.2% of the acid-exposed workers and 21.6% of the controls. The findings suggest that acid fumes in the workplace air do not increase the occurrence of oral mucous lesions but may lead to an increase in the prevalence of periodontal pockets.

National Trends in the Prevalence and Severity of the Periodontal Diseases

In summary, between the 1960 to 1962 national health survey and the 1971 to 1974 national health survey, the mean periodontal index scores remained unchanged. However, the classification of adults into broad disease categories showed that those with no evidence of disease increased significantly. This improvement in the nation's experience with the periodontal diseases was restricted to those with gingivitis, and a concomitant improvement was observed in the nation's oral hygiene status; debris scores decreased substantially, whereas little change was observed in calculus scores. Hypotheses have been raised in this paper about the decline in the prevalence of gingivitis and its possible association with variables such as OHI-S scores, socioeconomic status, dental care utilization, cigarette smoking, fluorides, and antibiotics. Also noted between the two surveys was a slight decrease in the prevalence of periodontal pockets in persons younger than age 35, whereas in persons older than 35, there was either no change or a slight increase. During this same period, both total loss of teeth and number of missing teeth per person decreased for all ages. A hypothesis is proposed that links this slight increase in the more severe signs of periodontal disease in older adults to an increase in the number of teeth at risk to the disease. The modest change in the prevalence and severity of advanced periodontal disease may be an early sign of a trend that will become accentuated as a result of a distinct increase in the nation's older population coupled with the increased retention of the natural dentition. Thus, it would seem that a decline in edentulism and an increase in number of teeth per person may well contribute to circumstances that will lead to greater, not lesser, risk of advanced periodontal disease problems in the later decades of life. Although this hypothesis may or may not hold true for today's younger adults as they age, it seems to be the likely occurrence for the nation's older adults, at least for the next several decades. A third national survey, using the same indexes and more current periodontal disease measures, is needed to help to clarify the trends reported here.
