Dental status of patients with mental disorders in a Nigerian teaching hospital: a preliminary survey

Although individuals with mental disorders are reported to experience dental problems similar to the general population, evidence suggests they actually have higher risks of dental disease and increased oral health needs. This study describes the dental status of 105 psychiatric outpatients in a Nigerian hospital. Information was obtained from subject interviews, medical records, and an oral examination to determine their dental caries and periodontal disease status. The oral hygiene status of the study participants was poor; the mean oral hygiene index score was 2.7 ± 1.20. The decayed, missing, and filled teeth ranged from 0 to 9 with a mean of 2.3 ± 2.28. Only five subjects (4.9%) had restorations and the mean number of filled teeth was .14 ± .67. The subjects’ age was significantly related to the mean oral hygiene score (p= .005), the mean gingival score (p= .006), and caries occurrence (p= .047). The oral health status of psychiatric patients in Nigeria is poor, indicating the need to provide oral health education and increase access to dental care for these patients.

Carrilho Neto A, De Paula Ramos S, Sant’ana ACP, Passanezi E. Oral health status among hospitalized patients. Abstract: Aim: To investigate into oral health status and its association with health status in hospitalized patients. Methods: A total of 82 patients were examined and 49 (59.7%) patients were men. The patients answered a survey and oral examinations to detect the number of teeth, oral hygiene index, prostheses hygiene, oral lesions, caries, dental plaque index (DPI), gingival inflammation index (GI), gingival bleeding index, periodontitis and periodontal index. Results: Oral hygiene was associated with age, but it was not related to physical disability. Difficulty eating was mainly associated with age and tooth loss. All full and partially dentate patients presented dental plaque, 38 (69%) poor oral hygiene, 58 (98.1%) gingival inflammation, 41 (74.5%) periodontal disease and 33 (60%) caries. Oral lesions were detected in 30 (36.5%) and candidiasis (n = 16, 19.6%) was the most frequent mucous lesion. Caries were associated with smoking and poor oral hygiene. Hospital length of stay and age were associated with increased DPI and GI. Conclusions: The majority of hospitalized patients did not present satisfactory oral hygiene. Caries and periodontal diseases are associated with health behaviours. Increased time length at hospital could increase gingival inflammation and dental plaque accumulation.     

Oral Health Status and Literacy/Knowledge Amongst Pregnant Women in Shanghai

BackgroundThe changes in hormones, diet, and hygiene associated with pregnancy are associated with oral diseases. There is insufficient awareness of the importance of oral health during pregnancy. This study investigated the oral health status and knowledge amongst pregnant women in Shanghai.MethodsThis cross-sectional study enrolled pregnant women at the Shanghai Red House Obstetrics & Gynecology Hospital in December 2020. The Fourth National Oral Health Questionnaire was used to evaluate the oral health status. Decayed/missing/filled teeth (DMFT) were the sum of the number of decayed, missing due to caries, and filled teeth. The chi-square test and Kruskal–Wallis test were used to compare the groups.ResultsA total of 224 pregnant women were enrolled. The rates of dental caries were 69.8%, periodontal health was 1.8%, calculus detection was 95.6%, shallow periodontal pocket was 51.1%, deep periodontal pocket was 4.9%, regular oral examination was 22.8%, correct brushing was 49.6%, and prepregnancy oral examination was 20.1%. DMFT was 2.27, and the caries filling ratio was 45.4%. The number of missing teeth increased with age (P < .001). Only 26.3% used dental floss more than once a day, 47.3% rinsed the mouth more than twice a day, and 46.9% cleaned their tongue coating every week. In addition, 99% of the pregnant women agreed that “oral health was vital to their lives” and 97.7% agreed that “regular oral examination was necessary.”ConclusionsThe oral health status amongst pregnant women in Shanghai was poor, but oral health awareness and attitudes were relatively high.     

Relationship of socioeconomic background to oral hygiene, gingival status, and dental caries in children.

OBJECTIVE: The aim of this study was to assess the relationship between socioeconomic status and oral hygiene, gingival condition, and dental caries among 12- to 15-year-old children. METHOD AND MATERIALS: Poor children of low-to-moderate socioeconomic status (n = 674) attending 10 public schools were chosen randomly from each of the five geographic areas in Irbid, Jordan. Rich children of high socioeconomic status (n = 347) attending 10 private schools were also included. Schoolchildren were examined for oral hygiene, gingival condition, and dental caries. RESULTS: Significantly higher proportions of children attending public schools had bleeding on brushing and calculus. Mean plaque and gingival scores were higher in public school children than in private school children, but the difference was not statistically significant. The public school children had higher overall scores for decayed, missing, or filled teeth and surfaces as well as higher scores for decayed teeth and surfaces, but there was no statistically significant difference between groups. However, children attending private schools had significantly more missing and filled teeth and surfaces. CONCLUSION: The findings for oral hygiene, gingival status, and dental caries were worse, but not significantly worse, among poor children than they were among rich children. Therefore, dental health education is recommended for both socioeconomic groups.

Hazza’a AM, Rawashdeh MA, Al‐Nimri K, Al Habashneh R. Dental and oral hygiene status in Jordanian children with cleft lip and palate: a comparison between unilateral and bilateral clefts. Abstract: Objectives: The purpose of this study was to assess and compare the dental health and oral hygiene status of subjects with unilateral and bilateral cleft lip and palate (BCLP). Methods: Oral and dental examinations were carried out in 98 children with cleft lip and palate and 98 unaffected subjects matching in gender and age, using the standard dental indices dmft and DMFT. Plaque and gingival indices were scored using the plaque and gingival indices of Silness and Löe. Results: The prevalence of dental caries was significantly higher in children with cleft lip and palate than their control in both permanent and deciduous teeth. Patients with BCLP experienced more dental caries than unilateral cleft lip and palate (UCLP) patients in both dentitions. Similarly, plaque accumulation and gingivitis were significantly higher in the cleft lip and palate patients compared with their controls. Only plaque accumulation was significantly higher in the BCLP patients than in the UCLP patients. Conclusion: Bilateral cleft lip and palate patients appear to be at a higher risk of caries experience and poorer in oral hygiene than those with UCLP patients. These findings not only provide a baseline for oral health parameters in patients with cleft lip and palate but also emphasize the need for intensive preventive measures of oral disease to optimize clinical outcome.     

Oral and dental findings in children with Fanconi anemia

PURPOSE: The purpose of this study was to investigate the oral and dental findings in children with Fanconi anemia (FA). METHODS: The study included 26 FA patients who came to the hospital (Hacettepe University Faculty of Medicine, Pediatric Hematology Unit) from the central region of Anatolia (17 [65%] mole, 9 [35%] female; mean age = 10.0 +/- 5.2 years (range = 2-18; median = 9 years]). Oral and radiological examinations and salivary collection were performed at the Department of Pediatric Dentistry of Hacettepe University Faculty of Dentistry. RESULTS: Among 26 FA children: (a) 16 (62%) had never visited a dentist; (b) 6 (23%) had visited a dentist once; and (c) 4 (15%) had visited a dentist regularly. Furthermore: (a) only 5 children (19%) brushed their teeth regularly; (b) 7 (27%) had never brushed their teeth previously; and (c) the other 14 (54%) had brushed their teeth rarely. The prevalence of dental caries was 35% in this study's patients. Gingival examination revealed that 9 (35%) children had gingivitis and the other 17 (65%) had normal gingival health status. Examination of the oral cavity revealed that: (a) 3 children (12%) had a coated tongue; and (b) 1 (4%) had papillary atrophy. No leukoplakia or other precancerous lesion was detected in this patient group. Salivary flow rate was less than 0.7 ml/minute in 56% of the patients. No patients had a salivary pH less than 5. Salivary buffering capacity of less than 5, however, was detected in 5 patients (33%). Radiological evaluation revealed that the most common congenital dental abnormalities were: (1) microdontia (44%); (2) congenitally missing teeth (26%); (3) transposition (9%); and (4) supernumerary teeth (4%). CONCLUSION: These results demonstrate that poor oral hygiene, dental decay, gingivitis, and congenital dental abnormalities--including generalized microdontia, supernumerary teeth, transposition, and congenitally missing teeth--are common oral and dental findings in this group of Turkish children with Fanconi anemia.     

The attitudes of parents toward the oral health of children and their reflection on the non-cavitated caries lesions

ObjectiveTo determine the extent of non-cavitated caries lesions in preschool children, and compare its relationship with socioeconomic status, oral and dental health practices, knowledge of caries prevention, and nutrition.Materials and methodsNinety-seven parents of 36–72 month-old children completed a questionnaire on the socioeconomic status of the family, parent's knowledge of caries prevention, the children's oral health practices, and nutrition. In the children, the cavitated dental caries were assessed according to World Health Organization (WHO) criteria and non-cavitated caries lesions on occlusal and smooth surfaces were evaluated by Universal Visual Scoring System (UniViSS). Statistical analysis was conducted using the SPSS software program. The relationships between variables were assessed using the chi-square test and logistic (ordinal) regression analysis.ResultsStatistically significant results were obtained relating to the parents' age, number of children, the time of first oral hygiene, frequency of tooth brushing, knowledge of caries prevention, drinks most often consumed by the children, and number of non-cavitated lesions. According to the regression model, the significant variables were caries activity (yes), drinks most often consumed by the children (milk–juice; juice–buttermilk), the frequency of tooth brushing (once a day, twice a day), observed changes in a child's teeth (change in color and breaks in teeth), the number of cavitated caries lesions and decayed, missing and filled teeth (dmft).ConclusionsThe primary factors contributing to non-cavitated caries lesions include the time of first oral hygiene and frequency of tooth brushing. The early diagnosis of non-cavitated caries is essential for preventive measures.     

Oral health status of children with Treacher Collins syndrome

There is a lack of data on the oral health status of individuals with craniofacial syndromes. A group of 15 children with Treacher Collins syndrome, aged 5 to 15 years old, was examined and evaluated for plaque, caries and gingival problems. The ability of the patients to clean their teeth was also investigated. A high plaque index and poor efficacy of tooth‐brushing was recorded. The caries and gingival indexes were not proportionally as high as the plaque accumulation. There was no association between the gingival index and presence of mouth breathing. There was predominance of the D component in both the dmft and DMFT indexes; this was associated with a need for restorative dental treatment in 60% of the patients, which indicated the need for dental care for these patients. Caretakers should be informed of the importance of oral health and oral hygiene and encouraged to take responsibility for the oral care of the children living at home.     

Fanconi's anemia: clinical and radiographic oral manifestations

BACKGROUND: Fanconi's anemia (FA) is a rare autosomal recessive disorder characterized by progressive bone marrow failure, congenital abnormalities, and predisposition to malignancies. There are 11 genetic subtypes characterized by complementation groups - FA- A, B, C, D1, D2, E, F, G, I, J, and L. OBJECTIVE: To evaluate and describe clinical, oral and radiographic manifestations of patients with FA. METHODS: A quantitative analysis of clinical manifestations, oral lesions and panoramic radiographs was performed in 33 patients. RESULTS: Clinical manifestations included melanin skin pigmentation, skin vascular and ocular anomalies. Melanin pigmentation on oral mucosa, traumatic lesions, gingival bleeding, dental biofilm and gingival alterations were the main oral manifestations that were found. Oral and clinical manifestations were not dependent on patient's sex. No significant statistical difference between females and males was detected. Dental anomalies were not remarkable either at clinical or at radiographic examinations. Although several dental anomalies were observed in patients with FA, the correlation between this disease was not established from this study. Panoramic radiographs showed agenesis, taurodontism, radicular anomalies such as dilaceration, tapering, and foreshortening. CONCLUSION: This study suggests that gingival alterations are associated with defective oral hygiene but not with hematologic conditions. It also helps elucidate oral manifestations of FA. These patients are living longer and need special dental care.

Kumar S, Motwani K, Dak N, Balasubramanyam G, Duraiswamy P, Kulkarni S. Dental health behaviour in relation to caries status among medical and dental undergraduate students of Udaipur district, India. Abstract: Objective: To compare the caries status and oral hygiene behaviour of dental and medical students and to assess the influence of oral hygiene behaviour on the caries status. Methods: A questionnaire survey was conducted to assess the knowledge, attitudes and behaviour along with clinical examination to asses the caries status. A total of 403 dental and medical students enrolled with Rajasthan University of Health Sciences of Udaipur district, India were recruited in the study. Results: 56.4% of dental students brushed their teeth twice daily compared to 38.5% of medical students. There was no significant difference between the mean decayed components of males and females of dental stream, whereas among medical subjects, males had a higher decayed score than females (P = 0.012). The mean behaviour score obtained by dental students (19.38) was greater than that of medical students (18.34). Moreover, medical students presented a higher decayed, missing and filled teeth (DMFT) score (1.96) than dental students (1.16). Subjects who had a habit of brushing after every meal showed lower DMFT score (1.4) than those who brushed only once a day (1.64). Step‐wise linear regression analysis revealed that course of education and final behaviour score were the best predictors for the DMFT status. Conclusion: This study revealed significant differences between the oral hygiene behaviour and caries status of dental and medical students; furthermore, caries status was significantly influenced by the oral hygiene behaviour.

Does caries risk assessment predict the incidence of caries for special needs patients requiring general anesthesia?

Objectives. The aim of this study was to correlate the caries-related variables of special needs patients to the incidence of new caries. Materials and methods. Data for socio-demographic information and dental and general health status were obtained from 110 patients treated under general anesthesia because of their insufficient co-operation. The Cariogram program was used for risk assessment and other caries-related variables were also analyzed. Within a defined follow-up period (16.3 ± 9.5 months), 64 patients received dental examinations to assess newly developed caries. Results. At baseline, the mean (SD) values of the DMFT (decayed, missing and filled teeth) and DT (decayed teeth) for the total patients were 9.2 (6.5) and 5.8 (5.3), respectively. During the follow-up period, new caries occurred in 48.4% of the patients and the mean value (SD) of the increased DMFT (iDMFT) was 2.1 (4.2). The patients with a higher increment of caries (iDMFT ≥3) showed significantly different caries risk profiles compared to the other patients (iDMFT <2) (p < 0.05). Close correlations existed between the caries increment and several caries-related variables; baseline DMFT, insufficient self-tooth-brushing and malocclusion were greatly associated with new caries development. Conclusions. Caries risk assessment could predict the incidence of future caries in hospital-based dentistry. Past caries experience and inadequate oral hygiene maintenance were largely related to caries development in special needs patients.     

The effect of bone marrow transplantation on systemic and oral health in Fanconi's aplastic anemia

Fanconi's anemia (FA) is an autosomal-recessive disorder characterized by a progressive pancytopenia, diverse congenital abnormalities and increased predisposition to malignancy. Sixteen children with FA, aged between 4 to 16 were divided into two groups according to treatments. Nine children had bone marrow transplantation and seven children were treated with steroid and/or anapolan. The changes in dental caries, caries-associated microflora, salivary status and periodontal health were investigated in children with FA. Data were analyzed by one-way ANOVA. A statistically significant difference was found in hematological findings between children who have received bone marrow transplantation (BMT+) and the others, who have not received (BMT-). There was no significant difference in dental caries experience, salivary flow rate, buffering capacity, mutans streptococci and Lactobacilli levels between the study groups. A statistically significant difference was found in gingival index, plaque index, bleeding on probing, probing depth scores between the patients with FA in BMT(+) and BMT(-) groups (p<.05). In conclusion, besides systemic control, additional preventive measures during their whole life to maintain oral health is necessary in these children.

Oral health status and practices of dentate Bhil adult tribes of southern Rajasthan,India

Aims : To assess the oral health status of the Bhil tribal population of Southern Rajasthan and to investigate the association of age, oral hygiene and dental visiting practices with oral health status. Design : A cross sectional study of Bhil tribal adults chosen by a multi stage stratified random sampling procedure. Participants : The total sample size was 1,590 male tribal dentate subjects aged 15–54 years. Methods : Clinical recordings of oral hygiene status (OHI ‐ S), caries status (DMFT and DMFS) and treatment needs, and periodontal status (CPI). The Chi square test was applied to discrete data and one way ANOVA for continuous data. Multivariate analyses were carried out to test the association of age, frequency of cleaning teeth, material used for cleaning teeth and dental visiting habits with caries and periodontal status. Results : Debris, calculus and oral hygiene index scores increased with age. The overall mean DMFT and DMFS scores were 5.34±6.48 and 18.94 ± 35.87 respectively. Extraction was the most required treatment (1.74 ± 3.66 teeth) followed by one surface fillings (1.34 ± 1.65 teeth). Shallow periodontal pockets were prevalent (40%) among the 35–44 years age group whereas deep pockets were most common (11.6%) in the oldest age group. More than half the sextants (3.15) were excluded amongst the oldest study group. All the independent variables namely age, frequency of cleaning teeth, substance used for cleaning teeth and visiting habits were statistically significantly related to caries and periodontal status. Conclusions : The study population was characterised by a lack of previous dental care, high treatment needs, high prevalence of periodontal disease and poor oral hygiene. Under these circumstances, the implementation of a basic oral health care programme for the Bhil population is a high priority.     

Predictors of root caries in the elderly

In an attempt to determine the association between overall health status, medication history, and oral hygiene status and root caries, 24 older persons residing independently in the community and 23 residents of a nursing home were interviewed and received oral examinations, using the Oral Hygiene Index and the Root Caries Index. The mean age of this population was 80 yr, with the nursing home subjects somewhat older than community-dwelling subjects. Only six persons had no root surface caries; three subjects had caries on all tooth surfaces with gingival recession. Mandibular teeth, particularly molars and premolars, showed the greatest attack rate. The best predictors of root caries were number of teeth remaining, calculus, plaque, and the use of medications with xerostomic effects. Medications were most predictive of maxillary root caries. The results point to the need to provide interceptive dental therapeutics for high risk geriatric populations such as those using multiple medications and with a poor history of oral care.     

Effect of localized experimental gingivitis on early supragingival plaque accumulation

Abstract Previous investigations have reported increased plaque formation in the presence of gingival inflammation as compared with gingival health. In these investigations, experimental gingivitis has been induced by total abolition of oral hygiene such that increased levels of salivary bacteria could contribute to the increased plaque formation. In the present study, experimental gingivitis was localized to 2 selected teeth whilst maintaining normal oral hygiene measures in the rest of the mouth. The aim of this study was to investigate whether the mass of plaque accumulating in a 3-day period is influenced by the inflammatory status of the adjacent gingival margins. Following scaling, prophylaxis and a period of optimal hygiene to establish gingival health, “plaque-guards” were worn during routine oral hygiene performance to prevent any cleaning on the buccal surfaces of teeth 14 and 15 from days 0 to 3. On day 3, accumulated plaque was removed from a 1.5 mm zone on the buccal surfaces of 14 and 15 adjacent to the gingival margins and weighed immediately. Subjects continued to wear their plaque-guards during oral hygiene until day 14 to induce experimental gingivitis around the experimental teeth. At day 14, all plaque was cleaned from the buccal surfaces of the experimental teeth and the mass of plaque accumulating over the next 3 days weighed on day 17. Comparison of plaque weights showed that the wet-weight of 3 day-old plaque was higher in the presence of experimental gingivitis than in the presence of gingival health (p= 0.02). This observation suggests that the inflammatory status of the marginal gingival has an important effect on early, supragingival plaque accumulation.     

A systematic review of population-based dental caries studies among children in Saudi Arabia

ObjectiveDental caries critically impacts the health and development of children. Understanding caries experience is an important task for Saudi Arabian policymakers to identify intervention targets and improve oral health. The purpose of this review is to analyze current data to assess the nationwide prevalence and severity of caries in children, to identify gaps in baseline information, and to determine areas for future research.MethodsA search of published and unpublished studies in PubMed, Google, and local Saudi medical and dental journals was conducted for the three keywords “dental,” “caries,” and “Saudi Arabia.” The inclusion criteria required that the articles were population-based studies that assessed the prevalence of dental caries in healthy children attending regular schools using a cross-sectional study design of a random sample.Results/discussionThe review was comprised of one unpublished thesis and 27 published surveys of childhood caries in Saudi Arabia. The earliest study was published in 1988 and the most recent was published in 2010. There is a lack of representative data on the prevalence of dental caries among the whole Saudi Arabian population. The national prevalence of dental caries and its severity in children in Saudi Arabia was estimated to be approximately 80% for the primary dentition with a mean dmft of 5.0 and approximately 70% for children’s permanent dentition with a mean DMFT score of 3.5. The current estimates indicate that the World Health Organization (WHO) 2000 goals are still unmet for Saudi Arabian children.ConclusionChildhood dental caries is a serious dental public health problem that warrants the immediate attention of the government and the dental profession officials in Saudi Arabia. Baseline data on oral health and a good understanding of dental caries determinants are necessary for setting appropriate oral health goals. Without the ability to describe the current situation, it is not possible to identify whether progress is being made toward these goals. A roadmap with a clear starting point, destination, and pathway is a desperately needed tool to improve the oral health of Saudi Arabian children.     

Clinical evaluation of medications on oral and dental health

OBJECTIVE: To evaluate the effect of medications on oral and dental health on a group of dental patients taking drugs regularly. METHODS: The study comprised two groups, the medication group included 328 dental patients regularly taking medication and the control group of 201 dental patients who took no medication. The patients were questioned about occurrence of self-reported oral dryness and were evaluated for the occurrence of any oral mucosal lesions, gingival recession, bleeding and enlargement, alveolar bone resorption, dental caries, any restorations and missing teeth were recorded. Data were statistically analysed with chi-square and Fisher's exact tests. RESULTS: There was no statistically significant difference (p > 0.05) between medication and control groups for oral mucosal lesions, gingival recession and enlargement but a statistically significant difference (p < 0.05) was found between the groups for oral dryness and gingival bleeding. Statistically significant differences (p < 0.05) were found between the groups for dental caries, amalgam, fixed and removable prosthetic restorations and missing teeth. CONCLUSIONS: There was a statistically significant difference for self-reported oral dryness and gingival bleeding and these factors may have been influenced by the increased rate of missing teeth and prosthetic restorations in the medication group.
