Periodontal diseases in children and adolescents

Associated factors of periodontitis and predicted study among young man in China: a population-based cross-sectional study

BACKGROUND

Periodontitis represents the foremost oral condition in young men, strongly correlated with socioeconomic elements and oral health behaviors. This research aimed to assess the prevalence of periodontitis and associated associations with socio-demographics and oral health practices for subsequent Hazard Ratio (HR) estimation.

METHODS

A total of 46,476 young men were recruited to the study between August 2022 and October 2023. A questionnaire on socio-demographic factors and oral health-related behaviors related to periodontitis was completed. The standard procedure was used for oral examination. Logistic regression and hazard ratios were used to estimate the influencing factors, whereas the nomogram was used to predict the risk of periodontitis in young men.

RESULTS

A total of 46,476 young men were surveyed and completed the questionnaire. The overall prevalence of periodontitis among young men was 1.74%. Out of these, 1.7% had mild periodontitis and 0.6% had moderate periodontitis. Age and dental calculus were important factors in the periodontal health of young men. This nomogram, which includes 7 easily obtainable clinical characteristics routinely collected during periodontitis risk assessment, provides clinicians with a user-friendly tool to assess the risk of periodontal disease in young men.

CONCLUSIONS

Regular dental prophylaxis is crucial for young men to maintain their gingival health and prevent the onset of periodontitis. Dental calculus plays a prominent role in this matter, as it serves as a significant contributing factor.

Self-perception of periodontal health and pain experience during periodontal examination in 14- to 15-year-old Danish adolescents

OBJECTIVE

To evaluate different aspects of periodontal examination among Danish adolescents.

MATERIALS AND METHODS

In all, 521 Danish adolescents underwent a periodontal examination and answered a questionnaire concerning their self-perception of periodontal health (PH). Furthermore, 107 participants reported their pain experience during periodontal examination using a visual analog scale. The self-perception of PH and the pain experience were correlated with plaque score (PS), bleeding on probing (BOP), probing pocket depth (PPD), and interdental clinical attachment loss (CAL).

RESULTS

Good PH was reported by 424 (81%) of the participants. However, the association between PH and PS, BOP, PPD, and CAL was small (sensitivity: 7.7, 7.8, 12.0, and 0.0%, respectively). Only 57 (11%) of the participants reported bleeding gums (BG) during tooth brushing, but the correlation with BOP showed a sensitivity of 11.7%. The specificity of both self-perception of PH and BG was high. Sixty-seven (66.6%) of the participants experienced 'mild pain' during periodontal examination. There were no differences in periodontal outcomes between the pain groups (p > .05).

CONCLUSIONS

The adolescents showed a poor ability to identify themselves as having poor PH and BG, and 67 (66.6%) of the adolescents experienced mild pain during periodontal examination. The findings emphasize the need for dental staff to monitor the PH of Danish adolescents and advise them as necessary.

The Six-Year-Old 'Adult'

Children are not miniature adults, yet when a child celebrates their sixth birthday, little do they know that, with the arrival of their first 'adult' tooth, they are about to gain their first real experience of being a 'grown-up'. The age of six is a key milestone in the mental, physical and emotional wellbeing of children, with most children in the UK having commenced primary school education by their fifth birthday. Six-year-olds are about to enter the most critical period in their dental development, the mixed-dentition phase, where their mouths are in a near continuous state of flux. This pivotal age in their dental development should not be undervalued; the dental decisions we make at this age means childhood lasts a lifetime. Caries is the most prevalent, preventable global disease, and with one in four children suffering from dental caries in the primary dentition by the time they start school, the foundations we lay down at the age of six translate into lifelong benefits for the permanent dentition. In this paper, the aim is to demonstrate that at the age of six we get a second chance to get things right. From caries risk factors and tailoring the five pillars of prevention by educating parents on the developing dentition, to reinforcing the importance of habit-breaking, developmental anomalies of enamel and early orthodontic intervention, this paper describes the importance of the age of six, never before so exclusively expressed in a dental sense.

Epidemiology and associated factors of gingivitis in adolescents in Guangdong Province, Southern China: a cross-sectional study

BACKGROUND

Gingivitis is the most prevalent form of periodontal disease in children and adolescents, being strongly associated to some socioeconomic factors and oral health behaviours. This study aimed to assess the prevalence of gingivitis and its association with socio-demographic factors and oral health-related behaviours in children aged 12-15 years in Guangdong, Southern China.

METHODS

A total of 7680 children were sampled using an equal-sized, stratified, multistage, random sampling method and clinically examined between December 2015 and April 2016. A questionnaire on socio-demographic factors and oral health-related behaviours related to gingivitis was completed by each of the selected children. Gingival bleeding was recorded using the Community Periodontal Index probe, and children with a gingival bleeding positive score ≥ 10% were defined as having gingivitis. A multivariate logistic regression analysis was performed to assess the association between socio-demographic factors and gingivitis. All statistical tests were performed at a two-sided significance level of 0.05.

RESULTS

The weighted prevalence of gingivitis among 12-15-year-old children was 29.6%, with 22.6% having localised gingivitis and 7.0% having generalised gingivitis. Age differences were observed in the prevalence of gingivitis, whereas urban-rural differences were not. According to the multivariate logistic regression analysis results, factors such as increasing age, being the only child, lack of regular annual dental check-up, and heavy dental calculus were significantly associated with higher prevalence of gingivitis. In addition, the association of gingivitis with these factors was inconsistent among the urban and rural areas.

CONCLUSIONS

Dental calculus and oral health behaviour were found to be important factors for maintaining the gingival health of children aged 12-15 years in Guangdong. Maintaining gingival health in children requires promoting positive oral health behaviours and regular dental prophylaxis.

Microbiomes in supragingival biofilms and saliva of adolescents with gingivitis and gingival health

BACKGROUND

Important alterations exist in the microbiomes of supragingival biofilm and saliva samples from adolescent patients developing induced or spontaneous gingivitis relative to healthy controls. These and the relationships to dental health are not fully understood yet.

SUBJECTS AND METHODS

Supragingival biofilm samples (n = 36) were collected from the teeth of 9 adolescents with gingivitis induced by orthodontic appliances, as well as dental plaques (n = 40) from 10 adolescents with spontaneous gingivitis, in addition to similar samples (n = 36) from 9 healthy controls. The bacterial metagenomes were analyzed by 16S rRNA gene amplicon sequencing. Salivary microbiomes of the same persons were characterized by shotgun metagenome sequencing. The data sets were examined using advanced bioinformatics workflows and two reference databases.

RESULTS

The composition and diversity of bacterial communities did not differ extensively among the three study groups. Nevertheless, the relative abundances of the genera Fusobacterium, Akkermansia, Treponema, and Campylobacter were prominently higher in gingivitis patients versus controls. In contrast, the genera Lautropia, Kingella, Neisseria, Actinomyces, and Rothia were significantly more abundant in controls than in either of the two gingivitis groups.

CONCLUSIONS

The abundance pattern of certain taxa rather than individual strains shows characteristic features of potential diagnostic value. Stringent bioinformatics treatment of the sequencing data is mandatory to avoid unintentional misinterpretations.

Gingival crevicular fluid levels of interleukin-18 and tumor necrosis factor-alpha in type 1 diabetic children with gingivitis

OBJECTIVE

This study aimed to evaluate the levels of interleukin-18 and tumor necrosis factor-alpha in gingival crevicular fluid of diabetic children with gingivitis.

METHODOLOGY

Eighty-eight children (44 with type 1 diabetes mellitus and 44 systemically healthy) were recruited for the study. The children were divided into four subgroups based on their periodontal and systemic condition: (1) systemically and periodontally healthy children (H), (2) systemically healthy children with gingivitis (G), (3) periodontally healthy children with T1DM (T1DM + H), and (4) children with T1DM and gingivitis (T1DM + G). The plaque index, gingival index, probing pocket depth, and GCF volume were recorded. The IL-18 and TNF-α levels in GCF were determined by ELISA.

RESULTS

The clinical periodontal parameters, GCF IL-18 level, and TNF-α level were similar between diabetic and systemically healthy children (p > 0.05). The gingivitis subgroups had a significantly higher GI, PI, PPD, GCF volume, and TNF-α total amounts than the H subgroups (p < 0.0001). The IL-18 concentrations in the gingivitis subgroups were significantly lower than in the periodontally healthy subgroups.

CONCLUSIONS

In diabetic children with good metabolic control, T1DM did not affect the GCF levels of IL-18 and TNF-α in the presence of gingivitis. However, increased GCF TNF-α levels in children with gingivitis confirm that TNF-α is closely related to gingival inflammation.

CLINICAL RELEVANCE

Type 1 diabetes mellitus is not associated with GCF interleukin-18 and tumor necrosis factor-alpha levels in children with gingivitis.

Paediatric periodontal screening methods in undergraduate dental schools

Introduction

Many forms of periodontal diseases affect children and adolescents. The simplified basic periodontal examination (BPE) is a screening tool for children aged seven to 17, which enables early recognition of such diseases. This study aims to investigate and compare methods of periodontal health assessments in the 'under-18s' across dental schools in the UK.

Materials and method

A web-based questionnaire was issued via email to teaching members of staff in each of the 16 undergraduate dental universities across the UK.

Results

Out of the 16 correspondents, ten universities completed the questionnaire, giving a response rate of 63%. All respondents were aware of methods of periodontal screening for children and adolescents such as the simplified BPE. All universities taught and used the 'simplified BPE'. The majority of universities started paediatric clinics in year three and carried out practical periodontal assessments in children aged seven and above, at first visit and at recall.

Discussion and conclusion

All UK dental schools were aware of, taught and used the simplified BPE as a method of periodontal assessment. Most universities seemed to comply with the guidelines being implemented.

Dental hypofunction alters subgingival microorganisms: a pilot study

BACKGROUND

The aim of this study was to evaluate dental plaque compositions, vascular endothelial growth factor (VEGF) and hypoxia-inducible factor (HIF) 1-alpha levels in gingival crevicular fluid (GCF) at hypofunctional and normofunctional teeth in healthy individuals and chronic periodontitis patients.

METHODS

Sixty systemically healthy individuals were enrolled. Study groups were: group 1 hypofunctional healthy group (group 1, N.=15); group 2 hypofunctional periodontitis group (group 2, N.=15); group 3 normofunctional healthy group (group 3, N.=15); and group 4 normofunctional periodontitis group (group 4, N.=15). Clinical periodontal measurements (plaque index, gingival index and clinical attachment level) were recorded. Dental plaque and GCF samples were taken. VEGF and HIF 1-alpha levels in GCF were determined. Subgingival plaque samples were evaluated for 11 different bacterial species as, Aggregatibacter actinomycetemcomitans, Porphyromonas gingivalis, Tannerella forsythia, Treponema denticola, Prevotella intermedia, Peptostreptococcus micros, Fusobacterium nucleatum, Campylobacter rectus, Eubacterium nodatum, Eikenella corrodens and Capnocytophaga species.

RESULTS

Tannerella forsythia, Peptostreptococcus micros, Eubacterium nodatum levels decreased in hypofunctional healthy and periodontitis groups (P<0.05). Porphyromonas gingivalis levels increased in hypofunctional healthy group and decreased in hypofunctional periodontitis group (P<0.05). There was also a decrease in Eikenella corrodens levels in hypofunctional periodontitis group (P<0.05). There were no difference regarding the Aggregatibacter actinomycetemcomitans, Capnocytophaga spp., Prevotella intermedia and Fusobacterium nucleatum levels among the groups (P>0.05). VEGF and HIF-1α levels in both GCF and serum samples were also similar (P>0.05).

CONCLUSIONS

Within the limits of this study, the authors found that the levels of four significant bacterial strains were decreased in both hypofunctional healthy and hypofunctional periodontitis groups compared to normofunctional equivalents. Though not evaluated in this study, this situation could be due to periodontal ligament atrophy and related physiological alterations.

Oral findings in children and adolescents with Prader-Willi syndrome

OBJECTIVE

To assess the significance of changes in the saliva in the etiology of gingivitis and tooth wear in children and adolescents with Prader-Willi syndrome (PWS).

MATERIALS AND METHODS

The study included 80 (2.8-18 years old; 39 girls and 41 boys): 40 in PWS group (mean age 8.0 ± 4.24 years) and 40 in control group (mean age 7.9 ± 4.12 years). General condition, oral para-functional habits, tooth wear (modified TWI), oral hygiene and gingival status (Plaque Index (PLI) and Gingival Index (GI)), localization of gingivitis, and salivary characteristics were assessed. The chi-square test, the Mann-Whitney U test, Spearman's rank correlation, and odds ratio based on logistic regression in a statistical analysis were applied.

RESULTS

Chances of gingivitis were increased by low PLI (odds ratio (OR) = 32.53), low resting salivary flow (OR = 3.96), increased viscosity of saliva (OR = 3.54), and mouth breathing (OR = 8.17). For gingivitis in anterior regions, low PLI (OR = 107.67), low resting (OR = 5.73) and stimulated (OR = 1.86) salivary flow, increased viscosity of saliva (OR = 5.87), mouth breathing (OR = 10.00), and low stimulated salivary flow (OR = 3.18) were observed. Tooth wear rates were increased by teeth grinding (OR = 16.20), mouth breathing (OR = 4.33), increased viscosity of saliva (OR = 11.67) and low resting (OR = 6.07), and stimulated (OR = 4.22) salivary flow.

CONCLUSIONS

In PWS, reduced salivary secretion, increased viscosity, of saliva and mouth breathing increase the risk of plaque-induced gingivitis and tooth wear.

CLINICAL RELEVANCE

The prevention and treatment of tooth wear and gingivitis in PWS patients is necessary not only to treat bruxism and mouth breathing but also to limit the influence of negative changes of saliva.

Socioeconomic inequalities and determinants of oral hygiene status among Urban Indian adolescents

OBJECTIVES

To assess the socioeconomic inequalities in oral hygiene and to explore the role of various socioeconomic and psychosocial factors as determinants of these inequalities among adolescents residing in Delhi National Capital Territory.

METHODS

A cross-sectional study was conducted among 1386 adolescents aged 12-15 years from three different socioeconomic groups according to their area of residence (middle-class areas, resettlement colonies and urban slum colonies). Level of oral hygiene was examined clinically using the Simplified Oral Hygiene Index (OHI-S), and an interviewer-administered questionnaire was used to measure key socio-demographic variables and psychosocial and health-related behaviours. Logistic regression analysis tested the association between area of residence and poor oral hygiene.

RESULTS

Poor oral hygiene was observed in 50.2% of the adolescents. There was a socioeconomic gradient in poor oral hygiene, with higher prevalence observed at each level of deprivation. These differences were only partly explained, and the differences between adolescent groups remained statistically significant after adjusting for various demographic variables, standard of living, social capital, social support and health-affecting behaviours (OR: 1.96, 95% CI: 1.30-2.76; and OR: 2.50, 95% CI: 1.60-3.92 for adolescents from resettlement colonies and urban slums, respectively, than middle-class adolescents).

CONCLUSION

Area of residence emerged as a strong socioeconomic predictor of prevalence of poor oral hygiene among Indian adolescents. Various material, psychosocial and behavioural factors did not fully explain the observed inequalities in poor oral hygiene among different adolescent groups.

Detection and diagnosis of periodontal conditions amenable to prevention

Gingivitis and chronic periodontitis are highly prevalent chronic inflammatory diseases. Gingivitis affects the majority of people, and advanced periodontitis is estimated to affect 5-15% of adults. The detection and diagnosis of these common diseases is a fundamentally important component of oral health care. All patients should undergo periodontal assessment as part of routine oral examination. Periodontal screening using methods such as the Basic Periodontal Examination/Community Periodontal Index or Periodontal Screening Record should be performed for all new patients, and also on a regular basis as part of ongoing oral health care. If periodontitis is identified, full periodontal assessment is required, involving recording of full mouth probing and bleeding data, together with assessment of other relevant parameters such as plaque levels, furcation involvement, recession and tooth mobility. Radiographic assessment of alveolar bone levels is driven by the clinical situation, and is required to assess bone destruction in patients with periodontitis. Risk assessment (such as assessing diabetes status and smoking) and risk management (such as promoting smoking cessation) should form a central component of periodontal therapy. This article provides guidance to the oral health care team regarding methods and frequencies of appropriate clinical and radiographic examinations to assess periodontal status, to enable appropriate detection and diagnosis of periodontal conditions.

Factors that influence the preventive care offered to adolescents accessing Public Oral Health Services, NSW, Australia

BACKGROUND

Many adolescents are at risk of dental caries and periodontal disease, which may be controlled through health education and clinical preventive interventions provided by oral health and dental therapists (therapists). Senior clinicians (SCs) can influence the focus of dental care in the New South Wales (NSW) Public Oral Health Services as their role is to provide clinical support and advice to therapists, advocate for their communities, and inform Local Health District (LHD) managers of areas for clinical quality improvement. The objective of this study was to record facilitating factors and strategies that are used by SCs to encourage therapists to provide preventive care and advice to adolescent patients.

METHODS

In-depth, semistructured interviews were undertaken with 16 SCs from all of the 15 NSW LHDs (nine rural and six metropolitan). A framework matrix was used to systematically code data and enable key themes to be identified for analysis.

RESULTS

All SCs from the 15 NSW Health LHDs participated in the study. Factors influencing SCs' ability to integrate preventive care into clinical practice were: 1) clinical leadership and administrative support, 2) professional support network, 3) clinical and educational resources, 4) the clinician's patient management aptitude, and 5) clinical governance processes. Clinical quality improvement and continuing professional development strategies equipped clinicians to manage and enhance adolescents' confidence toward self-care.

CONCLUSION

This study shows that SCs have a clear understanding of strategies to enhance the therapist's offer of scientific-based preventive care to adolescents. The problem they face is that currently, success is measured in terms of relief of pain activities, restorations placed, and extraction of teeth, which is an outdated concept. However, to improve clinical models of care will require the overarching administrative authority, NSW Health, to accept that the scientific evidence relating to dental care has changed and that management monitoring information should be incorporated into NSW Health reforms.

Preventive management plans recorded by dental therapists and oral health therapists using clinical vignettes for adolescents accessing public oral health services in New South Wales, Australia

BACKGROUND

The aim of this study was to investigate factors that influence dental therapists and oral health therapists (therapists) plan preventive oral health care for adolescents attending New South Wales public oral health services.

METHODS

A cross-sectional postal survey using two clinical vignettes was used to record the preventive care treatment plans offered by therapists working across 15 New South Wales local health districts. Data were tabulated and chi-square statistics used in the analysis.

RESULTS

One hundred and seventeen therapists returned questionnaires, giving a 64.6% response rate. The participants highlighted the importance of offering oral hygiene instruction (97.0%), dietary advice (95.0%) and topical fluoride applications (74.0%). Recommended home use products included fluoride toothpaste 5000 ppmF (59.0%) and casein phosphopeptide-amorphous calcium phosphate plus fluoride (CPP-ACPF) paste (57.7%). Over 50% used fissure sealants. More respondents (88%) would utilize motivational interviewing strategies for a patient with dental caries concerns; however, only 63% would use this technique for a patient in pain (p < 0.001).

CONCLUSIONS

Considerable variations were noted in therapists' recommendations for stabilizing and managing dental disease, suggesting a need for clinical directors to consider providing more advice to therapists on the scientific basis of preventing dental caries.

Preventive and clinical care provided to adolescents attending public oral health services New South Wales, Australia: a retrospective study

Background

Dental Therapists and Oral Health Therapists (Therapists) working in the New South Wales (NSW) Public Oral Health Service are charged with providing clinical dental treatment including preventive care for all children under 18 years of age. Adolescents in particular are at risk of dental caries and periodontal disease which may be controlled through health education and clinical preventive interventions. However, there is a dearth of evidence about the type or the proportion of clinical time allocated to preventive care.

The aim of this study is to record the proportion and type of preventive care and clinical treatment activities provided by Therapists to adolescents accessing the NSW Public Oral Health Service.

Methods

Clinical dental activity data for adolescents was obtained from the NSW Health electronic Information System for Oral Health (ISOH) for the year 2011. Clinical activities of Therapists were examined in relation to the provision of different types of preventive care for adolescents by interrogating state-wide public oral health data stored on ISOH.

Results

Therapists were responsible for 79.7 percent of the preventive care and 83.0 percent of the restorative treatment offered to adolescents accessing Public Oral Health Services over the one year period. Preventive care provided by Therapists for adolescents varied across Local Health Districts ranging from 32.0 percent to 55.8 percent of their clinical activity.

Conclusions

Therapists provided the majority of clinical care to adolescents accessing NSW Public Oral Health Services. The proportion of time spent undertaking prevention varied widely between Local Health Districts. The reasons for this variation require further investigation.

Simplified basic periodontal examination (BPE) in children and adolescents: a guide for general dental practitioners

Dental plaque-induced periodontal diseases are common in children and adults. Guidelines were previously not available for the periodontal screening of under 18s. However, new guidelines have been introduced by the British Society of Periodontology and the British Society of Paediatric Dentistry which set out recommendations for the periodontal screening and management of under 18s in primary dental care. This article provides a practical guide for general dental practitioners on how to use the BPE in children and adolescents, and highlights the importance of early detection and management of periodontal diseases in this age group. A failure to use the modified BPE in a young patient who is later diagnosed with periodontitis may leave a dentist vulnerable to a medico-legal complaint or claim.

CLINICAL RELEVANCE

New BPE guidelines for children and adolescents have been introduced by the BSPD and BSP; it is important that all dentists are aware of these guidelines and how to implement them in general practice.

Prevalence of Periodontal Bone Loss in Brazilian Adolescents through Interproximal Radiography

Purpose. The aim of this study was to verify the prevalence of alveolar bone loss in Brazilian adolescents through the interproximal X-rays analysis. Methods. Bilateral and standardized interproximal (bitewing) X-rays were performed in 15-year-old adolescents (n = 326), and the processing of films and measurements of alveolar bone levels were accomplished by a single examiner. A distance between the cementoenamel junction (CEJ) and the alveolar bone crest more than 2 mm was considered as periodontal bone loss. Results. The results showed percentage of bone loss of 10.4% with predominance of horizontal defects (8.9%) over the vertical types (1.5%). It was verified higher individual distribution of one lesion (67.6%) than two (26.5%) or three lesions (5.6%), and higher occurrence was detected in men (14.95) than in women (8.21). Conclusion. It can be concluded that the interproximal radiography was an efficient method for the detection of alveolar bone loss, revealing low prevalence in adolescents and predominance of horizontal bone defects.
