The Effect of Dental Flossing Instructions and Technique on Interproximal Bleeding: A randomized control trial

Purpose Dental floss has been promoted reduce the effects from interdental microbial biofilm, however its efficacy has been questioned in the literature. The purpose of this study was to compare daily flossing instructions using an adapted horizontal vertical flossing technique (AHVFT) and routine oral hygiene on gingival inflammation as indicated by bleeding on probing (BoP).Methods This randomized single-blinded controlled clinical trial was conducted with non-smoking adults presenting with gingivitis and no other systemic diseases. Eligible participants were recruited from a dental school patient population and were randomly assigned to one of two groups. Group A (experimental group) was instructed in how to use the AHVFT once daily and Group B (control group) was asked to continue with their regular oral hygiene practices. Clinical evaluations (interproximal BoP measurements) were performed by blinded, calibrated examiners at two, four, and eight-week intervals; the percentage of sites with interproximal BoP was recorded. Descriptive and inferential statistics were used to analyze the data.Results A total of 36 eligible participants were enrolled in the study: Group A (n=18), Group B (n=18). The mean (±SD) percentage of interproximal sites with BoP was 26.3 (±4.7), 8.6 (±7.3), 7.2 (±5.2), and 7.9 (±5.8) for Group A at baseline, two weeks, four weeks, and eight weeks, respectively. The corresponding values for Group B were 25.8 (±9.9), 15.6 (±12.4), 12.3 (±12.2), and 18.0 (±13.1), respectively. The percentage of sites with BoP was significantly lower for Group A than for Group B (p=.015 at two weeks, p=.009 at four weeks, and p<.001 at eight weeks). Within each group, the percentage of sites with BoP was significantly lower when compared with baseline (p<.008). At the final visit, the percent reduction in BoP for Group A was 70% and 30% for Group B compared with baseline. Most (88.2%) of Group A participants demonstrated mastery of the AHVFT at eight weeks.Conclusion Participants who received Instruction with the daily use of the AHVFT were shown to have reductions in interproximal BoP as compared to participants who had not received instructions in the AHVFT. Positive gingival health outcomes with dental flossing may be technique sensitive.

Addressing Oral Health Disparities of a Tribal Population Through a Combined Implementation of Focus Group Discussion, Mobile Technology Networking, and Creating a Supportive Environment: A Prospective Study

BACKGROUND AND OBJECTIVE

 Oral health disparities generally exist among tribal populations, prompting creative solutions to tackle these challenges. By using a combined implementation strategy of including focus group discussion (FGD), mobile technology networking (MTN), and creating a supportive environment, this study aims to assess and bring positive changes in oral health in these populations.

METHODS

The current study employed a mixed-method approach on a sample of 100 tribal volunteers. Qualitative assessment included FGD conducted regularly for three months based on themes such as oral hygiene habits, access to oral health, technology in oral health, the relationship of oral health to general health, and the role of diet in oral health. Quantitative evaluation included recording of the oral hygiene index-simplified and gingival index to measure gingival status. Messages on oral health were routinely posted to mobile phones to reinforce oral health education. Appropriate use of indigenous oral hygiene aids (neem and datun) was also taught during the discussion session. Clinical examinations were compared before and after FGD. Data were analyzed using IBM SPSS Statistics for Windows, Version 25 (Released 2017; IBM Corp., Armonk, New York, United States). A paired 't' test was used to find significant differences in gingival status at p<0.05.

RESULTS

The FGD sessions deduced observations such as limited access to dental care, inadequate oral hygiene practices such as usage of neem sticks and twigs, and lack of oral health awareness. The implementation of MTN facilitated the dissemination of oral health information and enhanced communication between community members and healthcare providers. The gingival index score significantly improved from pre-FGD to post-FGD with a mean difference of 0.41700 significant at p=0.000. Oral hygiene of the target population shifted from "Fair" oral hygiene status to "Good" oral hygiene status.

CONCLUSION

The combined implementation of FGD, MTN, and creation of a supportive environment demonstrated promising results in addressing oral health disparities among the tribal population. The interventions led to improved gingival status and better utilization of oral hygiene practices. These findings highlight the importance of tailored interventions, community engagement, and mobile technology in addressing oral health disparities in tribal populations. Ongoing support, sustainability, and further research are necessary to ensure the long-term impact and effectiveness of these interventions.

The efficacy of an oscillating-rotating power toothbrush compared to a high-frequency sonic power toothbrush on parameters of dental plaque and gingival inflammation: A systematic review and meta-analysis

AIM

To establish the efficacy of oscillating-rotating power toothbrush (OR-PTB) compared to high-frequency sonic power toothbrush (HFS-PTB) on improving parameters of plaque and gingival inflammation. Safety and participants' preference were secondary interests.

MATERIALS AND METHODS

MEDLINE-PubMed and Cochrane-CENTRAL databases were searched, up to April 2021. Inclusion criteria were (randomized)controlled clinical trials that evaluated healthy humans brushing with an OR-PTB compared to a HFS-PTB. Evaluation for a minimum of 4 weeks, of one or more of the following parameters: plaque index scores (PI), bleeding scores (BS), number of bleeding sites (NoB) and gingival index scores (GI).

RESULTS

Thirty two publications involving 38 comparisons were included after the independent screening. The descriptive analysis showed that in 54% of the comparisons, a significant difference in favour of the OR-PTB was found for PI, BS and GI scores. The Quigley and Hein index showed a significant difference of means (DiffM) between the end scores (DiffM 0.13, 95% CI [0.05;0.21] p < 0.001), as well as for the Rustogi-modified Navy index (DiffM 0.01, 95% CI [0.01;0.03] p = 0.002). This is in line with the meta-analysis for BS (DiffM 0.09, 95% CI [0.03;0.14] p = 0.003), for which the results were in favour of the OR-PTB and considered potentially clinically relevant. NoB showed a significant difference in favour of the OR-PTB for the end scores (DiffM 3.61, 95% CI [2.63;4.58] p < 0.00001). No difference in safety was indicated, 78% of participants preferred the OR-PTB.

CONCLUSION

For patients to maintain good plaque control and improve gingival health, there is a small but significant difference based on longer-term studies between OR-PTB and HFS-PTB. This difference is potentially clinically relevant.

Impact of Molar Incisor Hypomineralization on Oral Hygiene and Gingival Health in 8-15-years-old Children

BACKGROUND

This study aimed to evaluate the impact of molar incisor hypomineralisation (MIH) on oral hygiene and gingival health,and to investigate the relationship between these factors and the severity of MIH.

METHODS

A total of 72 children (48 with MIH and 24 healthy controls) were included in study.MIH severity was categorised into 3 groups:mild (n=16),moderate (n=16) and severe (n=16).The modified-Quigley Hein plaque index (m-QHPI) was used to determine oral hygiene,and the gingival index (GI) and bleeding on probe (BOP) were used to determine the gingival status of each subject. The Mann-Whitney U test was used for binary comparisons and the Kruskal-Wallis test was used for multiple comparisons.

RESULTS

The m-QHPI,GI and BOP were significantly higher in all individuals with MIH compared to the control group.The m-QHPI increased with the severity of MIH(p<0.001).The GI of the MIH-affected teeth had highly significant increases according to MIH severity(p<0.05).The mean BOP score for the entire mouth was significantly higher in patients with severe and moderate MIH than mild MIH(p<0.001).The mean BOP for affected teeth with moderate and severe MIH was significantly higher than the mean BOP of mildly affected teeth(p<0.05).

CONCLUSION

The presence and severity of MIH might be associated with increased plaque accumulation and gingival inflammation. © 2022 Australian Dental Association.

Effect of Stainless-Steel Crown and Preformed Zirconia Crown on the Periodontal Health of Endodontically Treated Primary Molars Correlating with IL-1β: An In Vivo Study

OBJECTIVE

The purpose of this study was to evaluate the effect of different crown materials on the interleukinone beta (IL-1β) content of the gingival crevicular fluid and to study which crown material causes the highest inflammation on the marginal gingiva on a biochemical basis in pediatric patients.

STUDY DESIGN

Twenty patients in the age group of 4-8 years with endodontically treated primary molars indicated for crown placement were selected for the study which was further divided into 3 groups for sample consideration: group 1-stainless steel crown, group 2-preformed zirconia crown, and group 3- control group (primary second molar). All assay procedures were carried out and the results of the collected samples were calculated using the ELISA-AID TM technique.

RESULTS

On mean comparison among the groups using ANOVA oneway test, P-value turns out to be highly significant, on mean comparison using Tukey's HSD post-hoc test, The p-value was 0.000 ,0.000 ,0.193 on comparing group 1 with group 2, group 1 with group 3, group 2 with group 3 respectively.

CONCLUSION

Preformed zirconia crown can be a relative replacement of SSC in primary molars as it causes comparatively less inflammation and with an advantage of esthetics.

Clinically Healthy Human Gingival Tissues Show Significant Inter-individual Variability in GCF Chemokine Expression and Subgingival Plaque Microbial Composition

Aim: Clinically healthy gingival tissue is maintained through controlled regulation of host defense mechanisms against plaque biofilm overgrowth. One key component is the transit of neutrophils from the vasculature into gingival tissue where the expression of different neutrophil chemokines are tightly regulated. This cross-sectional study examines the inter-individual variability in chemokine profiles within gingival crevicular fluid (GCF) in relation to the subgingival bacterial community in a state of gingival health. Methods: Gingival crevicular fluid and subgingival plaque samples were collected from mesiobuccal surfaces of all six Ramfjord teeth of 20 systemically healthy individuals (14.55 ± 1.67 years). A multiplex immunoassay was carried out to quantify the expression of 40 different chemokines in the healthy gingival tissue. Neutrophils were assessed indirectly by myeloperoxidase (MPO) in GCF using traditional ELISA. Characterization of healthy subgingival plaque was conducted with the Illumina Miseq targeting the 16S rRNA gene. Results: In health, there are distinct variations within individual gingival crevicular fluid chemokine expression profiles, as well as in the concentration of neutrophils, that divided the participants into high or low chemokine expressing groups. Specifically, key differences were identified within MIF (2683.54 ± 985.82 pg per 30-s sample), IL-8/CXCL8 (170.98 ± 176.96 pg per 30-s sample), Gro-α/CXCL1 (160.42 ± 94.21 pg per 30-s sample), ENA-78/CXCL5 (137.76 ± 76.02 pg per 30-s sample), IL-1β (51.39 ± 37.23 pg per 30-s sample), TNF-α (1.76 ± 1.79 pg per 30-s sample), and IFN-γ (0.92 ± 0.54 pg per 30-s sample). Of these identified chemokines, the highest correlation was associated between IL-8/CXCL8 and neutrophils (r = 0.54, p = 0.014). Furthermore, species characterization of healthy subgingival plaque revealed significant inter-individual variability that identified two unique groups unrelated to the previously identified chemokine groups. Conclusion: The lack of concordance between the microbial composition and chemokine profile during health may be a reflection of the unique microbial composition of each individual coupled with variations within their host response, emphasizing the vast complexity of the defense mechanisms in place to maintain gingival health.

Isolation and Description of Catonella massiliensis sp. nov., a Novel Catonella Species, Isolated from a Stable Periodontitis Subject

The genus Catonella currently counts a unique species, C. morbi, isolated from periodontal pockets and associated with periodontitis and endodontic infections. This study contributed to the taxonomical and clinical knowledge of this genus by describing a novel species isolated from a saliva sample from a man in clinical gingival health following successful treatment of periodontitis. Morphological and chemotaxonomic characteristics were investigated using different growth conditions, pH, and temperature. Cellular fatty acid methyl ester (FAME) analysis was conducted by gas chromatography/mass spectrometry (GC/MS). Phylogenetic analysis based on 16S rRNA, orthologous average nucleotide identity (OrthoANI), and digital DNA-DNA hybridization (dDDH) relatedness were performed. Strain Marseille-Q4567^T was found to be an anaerobic and non-spore-forming rod-shaped bacterium that grew at 28–41.5 °C (optimum 37 °C), pH 6.5–8.5 (optimum pH 7.5), and 5–10 g/L of NaCl (optimum 5 g/L). The predominant cellular fatty acid was C16:0 (64.2%), followed by unsaturated structures C18:1n9 (12.5%) and C18:2n6 (7.8%). Based on 16S rRNA sequence comparison, the closest phylogenetic neighbor was C. morbi ATCC 51271^T (98.23% similarity). The OrthoANI and dDDH values between strain Q4567^T and C. morbi ATCC 51271^T were respectively 79.43% and 23.8%. Therefore, we concluded that strain Marseille-Q4567^T represents a novel species of the genus Catonella, for which the name Catonella massiliensis sp. nov. is proposed (= CSUR Q4567).

The efficacy of a rubber bristles interdental cleaner on parameters of oral soft tissue health-a systematic review

Aim

This study aimed to establish the efficacy of a rubber bristles interdental cleaner (RBIC) as an adjunct to toothbrushing (TB) compared to that of the adjuvant use of other interdental cleaning devices and TB alone on plaque and gingivitis parameters. Additionally, the safety aspects and panellists’ appreciation were evaluated.

Materials and Methods

Databases were searched for randomized controlled clinical trials (RCTs) evaluating plaque (PI), bleeding (BS), and gingival index (GI) scores, safety assessments, and participants’ appreciation. Extracted data were summarized in a descriptive and, if possible, a meta‐analysis.

Results

The search retrieved 142 unique papers; six studies with 10 comparisons were included in a descriptive analysis. Five RCTs compared RBICs with interdental brushes (IDBs), four with dental floss (DF) and one with manual TB only. No comparisons to wood sticks were retrieved. Using an RBIC resulted in no difference in plaque scores compared to DF and IDBs. For overall bleeding scores, no difference was found. Two studies analysing the accessible sites separately found RBICs to be more favourable than DF and IDBs. Conversely, one study evaluating the efficacy of RBICs compared to IDBs, according to the GI scores, showed that IDBs achieved significantly greater reduction. Moreover, RBICs caused fewer gingival abrasions and were preferred by the study participants.

Conclusion

Based on a descriptive and a meta‐analysis of the available literature, it is synthesized that in gingivitis patients, a weak to very weak certainty exists that a RBIC is indicated for gingivitis and plaque reduction. The evidence supports user safety and participants’ preferences.

Evaluation of the efficacy of a commercially available regimen vs brushing alone on established plaque and gingivitis on adolescents: Study protocol for a randomized, controlled, blind clinical trial

BACKGROUND

Dental biofilm accumulation and poor personal oral hygiene are known major risk factors for gingivitis and halitosis. However, it is not clear how studies compare the effectiveness of hygiene regimens, associated with outcomes centered on patients.

METHODS

A randomized, blind, controlled clinical trial involving 58 participants aged from 12 to 17 years, who search the Department of Pediatric Dentistry of Universidade Metropolitana de Santos, will be conducted. Immediately, the volunteers will be inserted into Group 1 (commercially available hygiene regimen) or Group 2 (tooth brushing alone). In Group 1, participants will receive Colgate Total 12 toothpastes, Plax mouthwashes and Colgate Ultrasoft toothbrushes, while Group 2 will use Colgate Cavity Protection toothpastes and Colgate Ultrasoft toothbrushes. The interventions will be conducted in the periods of 1, 3, and 6 months after the baseline, when the evaluations will also be performed. Biofilm and halitosis indexes will be evaluated. Data regarding discomfort, satisfaction and the socioeconomic/individual characteristics will also be computed.

DISCUSSION

Although toothbrushing has shown positive effects in decreasing biofilm and in gingival health, there is no comparison in the literature of different brushing regimens with halitosis measurement in adolescents. In addition, the effectiveness of these protocols would be confirmed from the acceptability of the volunteers.

Effect of a health-education program using motivational interviewing on oral health behavior and self-efficacy in pregnant women: a randomized controlled trial

Oral health problems are common among pregnant women. The objective of this study was to examine the effectiveness of motivational interviewing (MI) as a behavior-change technique to enhance self-efficacy and oral health among pregnant women. A randomized controlled trial was conducted with 112 pregnant Iranian women. Women in the intervention group received an education program on oral health using MI during two face-to-face sessions, along with routine health education (two 1-h lectures on oral health changes and needs during pregnancy presented as a lecture by an oral health technician over a 2-wk period). Those in the control group received two 1-h lectures on oral health changes and needs during pregnancy. Oral health behaviors, oral health self-efficacy, and general self-efficacy, were assessed, along with gingival and dental health from baseline to the 3-month follow-up. Analysis of covariance was used to determine differences between intervention and control groups. Scores for both general and specific self-efficacy and for healthy behaviors increased in the intervention group, whereas there was no significant change within controls from baseline to follow-up. Between-group analyses also indicated a significant difference in the scores for self-efficacy and behavior favoring the intervention group. Scores on the gingival inflammation index decreased, as did the number of decayed teeth in the intervention group relative to the control group. The number of filled teeth increased significantly in the intervention group. Health education interventions using MI techniques may help to improve oral health-related self-efficacy and behaviors among pregnant women.

Self-regulation in oral hygiene behaviours in adults with gingivitis: The mediating role of coping planning and action control

AIM

This study investigates the joint role of volitional predictors of oral hygiene behaviours of flossing and brushing in adults with gingivitis, framed by the Health Action Process Approach model (HAPA).

MATERIALS AND METHODS

In a longitudinal online survey, 201 participants aged 18-75, of which 56.7% were women, completed assessments at baseline(T1), 2 weeks(T2) and 4 months(T3). Oral hygiene behaviours(OH) (brushing and flossing) and social cognitive determinants of behaviour in the HAPA: action and maintenance self-efficacy(ASE & MSE), intention(INT), coping planning(CP) and action control(AC) were evaluated. Structural equation modelling was used to test a series of three nested models. In Model 1, action self-efficacy would determine MSE and INT, and INT would determine OH; in Model 2, INT would determine both CP and AC and the two OH behaviours; and in Model 3, CP and AC would be sequential mediators between INT and OH.

RESULTS

Model 3, predicting a mediating process from intention to behaviour via coping planning and action control, showed the best fit according to the fit indices and explained more of the variance in dental hygiene. The mediating role of coping planning and action control between intention and oral hygiene behaviours was thus confirmed. Importantly, coping planning did not mediate between intention and oral hygiene behaviours, which means that oral hygiene intention influences action control through coping planning, and both sequentially mediate this influence on behaviour.

CONCLUSIONS

For individuals who are not yet following the recommendations for specific oral hygiene behaviours, coping planning and action control represent psychological mechanisms by which intentions are put into practice.

Impact of Fixed Orthodontic Appliance and Clear Aligners on the Periodontal Health: A Prospective Clinical Study

This study aimed to evaluate the periodontal health of orthodontic patients with supportive periodontal therapy in a 3 month follow-up. The sample comprised 20 patients (mean age 20.6 ± 8.1 years) in treatment with multibracket fixed appliances (fixed group-FG) and 20 patients (mean age 34.7 ± 12.5 years) in treatment with clear aligners (clear aligners group-CAG). At baseline (T0) and after 3 months (T1), probing depth (PD), plaque index (PI), bleeding on probing (BOP), and gingival recession (REC) were measured. Patients were trained to perform an individualized tooth brushing technique, and every 2 weeks they were re-called to reinforce the oral hygiene instructions. The intra-group comparisons (T1 vs. T0) were calculated with the Wilcoxon signed-rank test, while a linear regression model was used for the inter-group comparisons (FG vs. CAG). The significance level was set at p < 0.05. Statistically significant decrease in both groups was found for PD (FG: Δ, -9.2 inter-quartile range (IQR), -22.5, -5.5; CAG: Δ, -12.6 IQR, -25.4, -4.8), BOP (FG: Δ, -53.5 IQR, -70.5, -37; CAG: Δ, -37.5 IQR, -54.5, -23), and PI (FG: Δ, -17.5 IQR, -62.5, 14.5; CAG: Δ, -24 IQR, -49.5, -5). The result of the linear regression models suggested that the type of appliance did not have any effects on the improvement of periodontal variables. Therefore, patients undergoing orthodontic treatment with fixed appliances and clear aligners did not show differences in gingival health when followed by a dental hygienist.

A Randomized Parallel Study to Compare the Effects of Powered and Manual Tooth Brushing on Gingival Health and Plaque

OBJECTIVES

To compare the effect of powered and manual tooth brushing on plaque and gingivitis following two and six weeks of home use.

METHODS

This was a randomized, three-arm, parallel-design clinical trial. Eligible participants were manual toothbrush users who were generally healthy non-smokers, aged 18-65 years, with a plaque score of = 1.8 per Lobene and Soparkar Modified Plaque Index (MPI), and mild to moderate gingivitis, defined as a Gingival Bleeding Index (GBI) = 1 on at least 20 sites. Subjects with advanced periodontal disease, excessive gingival recession, and heavy deposits of calculus or rampant decay were excluded. Enrolled participants were randomly dispensed one of three devices: a powered toothbrush (Philips Sonicare DiamondClean Smart with Premium Gum Care brush head) used in either Gum Heath mode (DC-GH) or Clean mode (DC-C), or an ADA reference manual toothbrush (MTB). Efficacy and safety variables were assessed at Baseline, and at two and six weeks following twice-daily product home use.

RESULTS

For the primary endpoint, reduction in gingivitis per Modified Gingival Index (MGI) at Week 2, 188 subjects completed and were included in the analysis. Expressed as percent reduction from Baseline, the adjusted mean reduction and Standard Error (SE) estimates were 60.31% (1.95%) for DC-GH, 53.08% (1.95%) for DC-C, and 16.59% (1.96%) for MTB. The difference between each power toothbrush group and the manual toothbrush was statistically significant (p < 0.0001). Statistically significant differences were also observed between DC-GH, DC-C, and manual tooth brushing for MGI at Week 6, as well as for MPI and GBI at Weeks 2 and 6.

CONCLUSIONS

The powered toothbrush, used in either Gum Health or Clean mode, was statistically significantly superior to a manual tooth brush in reducing gingival inflammation, gingival bleeding, and plaque following two and six weeks of home use.

Evaluation of 0.2% delmopinol mouth rinse for prevention of peri-implant mucositis and peri-implantitis: A randomized controlled canine study

OBJECTIVES

To evaluate the effectiveness of 0.2% delmopinol mouth rinse in maintenance of peri-implant tissue health and prevention or inhibition of peri-implant mucositis and peri-implantitis.

MATERIALS AND METHODS

Four weeks following tooth extraction, eight titanium dental implants, were placed in six dogs' mandibles. Three dogs were assigned to the test or placebo mouth rinse. Eight weeks following implant installation (T2) ligature was placed to induce peri-implant disease. Clinical and radiographic assessment was performed during the study period as well as micro-CT analysis and histologic assessment to evaluate Bone-Implant Contact at the end of the follow-up (T4).

RESULTS

Plaque at implant sites before ligature placement (T2) was lower for the test group (0.7 ± 1.0 vs 1.5 ± 1.3, P < .05). The ratio of affected implant (PD ≧4 mm) at T2 and T4 in the test group was significantly smaller than that of the placebo group (T2, 17% vs 47%, P < .01; T4, 67% vs 83%, P < .05). The test agent also seemed to be effective in partially preventing bone loss induced by ligature placement according to the Computed Tomography and histologic analysis (test, 1.1 ± 0.8 mm; placebo, 1.5 ± 0.9 mm).

CONCLUSIONS

Within the limits of this animal model study, the results of the study indicate that the 0.2% delmopinol rinse might play a role in prevention of peri-implant disease development.

Assessment of dental caries and gingival status among a group of type 1 diabetes mellitus and healthy children of South India - a comparative study

Background Diabetes mellitus is a metabolic disorder. However, dental caries and periodontal health have not attracted much interest in diabetic patients. This study was carried out to assess the dental caries status and gingival health status in children with type 1 diabetes mellitus (T1DM). Methods The study group consisted of 80 children, aged 6-18 years, with T1DM. The dental caries status was recorded using the World Health Organisation (WHO) criteria. Gingival health was assessed using the Loe and Silness gingival index (GI). Data obtained were subjected to statistical analysis. Results The mean dental caries status for primary (decayed, extracted, filled teeth [deft]) and permanent dentition (decayed, missing, filled teeth [DMFT]) scores in diabetic children were 0.44±1.28 and 1.26±2.49, respectively. The GI scores of diabetic children were 0.33±0.48. GI in the study group significantly correlated with DMFT (p<0.001) and deft (p≤0.05). Conclusions Dental caries in primary dentition was lower in diabetic children but was not statistically significant, whereas dental caries in permanent dentition was significantly higher. The gingival condition of diabetic children was healthy.

Oral health and glycosylated hemoglobin among type 1 diabetes children in South India

BACKGROUND

The study was an attempt to evaluate the relationship between oral health status and the level of glycemic control in type 1 diabetes patients.

METHODS

The study was carried out in 87 children with type 1 diabetes, aged 8-16 years, attending a diabetes specialty hospital. The oral health of these patients was measured using the WHO 1997 Oral Health Survey criteria for diagnosis of dental caries, gingival index, and plaque index. Samples were then divided into two groups as controlled (≤6.99% glycosylated hemoglobin [HbA1c]) and uncontrolled (≥7% HbA1c) diabetes as per the guidelines for glycemic control in diabetics given by the American Diabetes Association. The oral health between the groups was compared.

RESULTS

Data were statistically analyzed using student t-test. Results showed a significant difference in decayed, missing, and filled surface component (P = 0.043) and gingival index scores (P< 0.001) in the permanent dentition between controlled and uncontrolled groups but not in case of the primary dentition.

CONCLUSIONS

The data findings suggest that metabolic control had an impact on caries prevalence and gingival health of these patients, in case of permanent dentition. As the glycemic control became poorer, the caries prevalence and gingival inflammation increased. When primary dentition was taken into consideration, the correlation was not significant.

Oral health status among children and adolescents in governmental and private schools of the Palestinian Territories

BACKGROUND

Political conflicts in the Palestinian Territories (PT) have resulted in systematic deterioration of socio-economic conditions and health. The World Health Organization (WHO) has emphasised the negative impacts of social crisis on children' oral health and quality of life.

OBJECTIVES

To assess the prevalence and trends in dental caries and poor gingival health of schoolchildren in the PT through the scholastic years 1998/1999 to 2012/2013.

METHODS

This is a retrospective study. Prevalence data on dental caries of primary and permanent dentitions among children 6, 12 and 16 years of age were gathered from annual oral health reports of the School Dental Health Programme (SDHP)-Ministry of Health. Caries was recorded according to WHO methods and criteria. Decayed, missing and filled teeth indices for primary (dmft) and permanent (DMFT) teeth were calculated. Gingival health status was examined according to the Community Periodontal Index (scores 1 and 2). Statistical analysis used SPSS.

RESULTS

In 2012/2013, dental caries prevalence rates and the index scores among schoolchildren were as follows, respectively: 56.4% and 2.7 dmft at age 6; 42.0% and 1.4 DMFT at age 12; and 38.7% and 1.7 DMFT at age 16. For all age groups, the d/D-component of the caries indices was high. Trends of dental-caries prevalence, caries experience and gingival bleeding were fairly constant over time from 1998/1999.

CONCLUSION

The SDHP was established in order to prevent and control oral diseases among schoolchildren in the PT. The Programme is fairly passive and the survey indicates an urgent need for reorientation of activities towards population-based prevention and health promotion. The application of the WHO Health Promoting Schools concept is highly recommended.

Efficacy of a rubber bristles interdental cleaner compared to an interdental brush on dental plaque, gingival bleeding and gingival abrasion: A randomized clinical trial

AIM

To determine the efficacy of a rubber bristles interdental cleaner (RBIC) compared to an interdental brush (IDB) in reducing gingivitis and additionally to evaluate participants' attitudes and possible side effects.

MATERIAL AND METHODS

The study was a 2-treatment, parallel, split-mouth, examiner-blind RCT, evaluating the reversal of experimental gingivitis. In total, 42 systemically healthy volunteers were recruited that were currently non-users of interdental cleaning devices. After familiarization and prophylaxis, participants refrained from brushing mandibular teeth for 21 days, followed by 4-week product use of the assigned interdental cleaning device as adjunct to manual toothbrushing. Bleeding on marginal probing (BOMP), dental plaque index score (PI) and gingival abrasion score (GAs) were assessed in the lower jaw.

RESULTS

Overall, no statistically significant differences between the RBIC and IDB in reducing BOMP and PI were obtained. Analysing the sites that were accessible for the RBIC/IDB only showed that the sites treated with the RBIC had significantly less BOMP after 4 weeks (P = .009). The RBIC also caused less GAs (P => .016) and was considered more pleasurable to use by the participants (P = .0001).

CONCLUSIONS

In accessible sites, the RBIC, in conjunction with manual toothbrushing, was found to be more effective in reducing gingival inflammation after 4 weeks. The RBIC caused less abrasion of the gingiva and was appreciated more by the participants.

Incidental findings of implant complications on postimplantation CBCTs: A cross-sectional study

BACKGROUND

Survival rates of dental implants are reported to be very high and seem to indicate minimal complications related to dental implants.

PURPOSE

The aim of this report was to evaluate in a cross-sectional study the prevalence of implant positioning complications as appears in postimplantation Cone-Beam Computerized Tomography (CBCT) in two of the major imaging facilities in Bucharest, Romania.

METHODS

Demographic and implant data was collected from two of the three main CBCT facilities in Bucharest, Romania. All postimplantation CBCT imaging were assessed and evaluated for the presence of different implant positioning related complications. Data were entered into Excel spreadsheet and analyzed statistically.

RESULTS

Of the 2323 CBCT's that were analyzed, a total of 160 (6.89%) presented with implant positioning related complications. Out of those, 62 cases revealed penetration of the implant to adjacent anatomic structure. More specifically, there were 21 instances of sinus penetration, 19 instances of nasal cavity penetration, 9 instances of inferior alveolar canal penetration, and 13 instances of lingual plate perforations. There were also 15 cases of adjacent tooth injury noted.

CONCLUSIONS

Despite the popularity of dental implants, the surgical placement of these implants is not a riskless procedure. Implant mal-positioning might be life-threatening and can lead to serious bleeding, airway obstruction, and unnecessary postoperative surgeries. Complications of dental implants are not obsolete and dental implant associated problems may not be apparent immediately. Surgeons must have proper training and use evidenced-based treatment planning in order to prevent dental implant complications.

Oral health status, salivary pH status, and Streptococcus mutans counts in dental plaques and saliva of children with acute lymphoblastic leukemia

Background:

Acute lymphoblastic leukemia (ALL), accounting for 23% of all malignancies in children, is the most prevalent pediatric malignancy. This study compared dental caries, oral hygiene status, salivary pH, and Streptococcus mutans counts in dental plaques and saliva of children with leukemia with those of healthy controls.

Materials and Methods:

This case–control cross-sectional study assessed 32 children with ALL and 32 healthy children (4–9-year-old) for gingival bleeding index (GBI), decayed, missing, and filled/decayed, missing, and filled surfaces (DMF/dmfs), and plaque index (PI). Sampling was performed to determine salivary pH and S. mutans counts of the participants. The two groups matched in terms of age, gender, and socioeconomic status. The groups were compared using independent t-test, Mann–Whitney test, Chi-square test, and Spearman's and Pearson's correlation analyses.

Results:

The mean DMF/dmfs and GBI were significantly higher in the ALL group (P_DMF/_dmfs= 0.03; P_GBI= 0.04). However, the two groups were not significantly different in the mean PI values (P = 0.47). The mean S. mutans counts in dental plaques and saliva of the children with leukemia were significantly lower than the healthy controls (P < 0.01). Moreover, the mean salivary pH was significantly lower in the ALL group compared to the control group (P < 0.01).

Conclusion:

Higher caries and gingival bleeding rates, higher dental plaque accumulation in children with ALL, decreased salivary pH, and cumulative effects of other risk factors highlight the significance of oral hygiene training programs (for the parents of these children) and regular dental examinations for these children.

Non-surgical management of tooth hypersensitivity

Tooth sensitivity is a common complaint of patients in dental practices. Studies have demonstrated dentinal hypersensitivity to affect 10-30% of the population. There are various potential causes of tooth sensitivity and a variety of available treatment options. This narrative review will discuss the possible aetiology of this condition, as well as the treatment modalities available. A tailor-made treatment plan that starts with the most non-invasive treatment options and escalates only when those options have proven insufficient in alleviating symptoms should be provided for each patient. Only after all non- and less-invasive methods have failed to reduce the symptoms should more invasive treatment options, such as root-coverage, be considered.

Improving oral hygiene skills among children undergoing treatment at the haemato-oncology department - an interventional programme

OBJECTIVES

The aim of this interventional programme was to educate children undergoing treatment at the haemato-oncology department in how to improve their oral hygiene skills.

METHODS

Children (and their parents) treated at the haemato-oncology department for haematological malignancies and disorders were educated and instructed in how to improve their dental oral hygiene skills. Instructions, demonstration and practice of toothbrushing techniques, as well as interproximal cleaning, were carried out in three separate sessions. In each session, toothbrushing skills were evaluated using the Ashkenazi index to assess improvement in oral hygiene skills over time. Four assessments were performed and recorded for each participant: before the initial explanation; immediately following the explanation; and 3 and 6 weeks following the first visit.

RESULTS

Overall, 52 children were enrolled in the programme. The first toothbrushing performance skill evaluation revealed a low score of 10.44 out of a total of 40; this was significantly increased, following the instruction session, to 33.02 (P < 0.001). This improvement was maintained at the follow-up visits at 3 weeks (35.09 ± 6.3) and 6 weeks (36.34 ± 8.3). Following the instructions, a significant increase was accomplished in both 'reach' and 'stay' components of the score, to 18.44 out of 20 for 'reach' and 17.9 out of 20 for 'stay' at the last visit (P < 0.01).

CONCLUSIONS

Individual supervised toothbrushing education, including a methodological toothbrushing technique, appears to be very effective. Educating medically compromised high-risk patients, such as hospitalised children, might be a good way to improve oral health and prevent future disease in this population.

Oral hygiene and gingival health status of children with Down syndrome in Yemen: A cross-sectional study

Purpose:

The objective of the present study was to assess the oral hygiene and gingival health status among Yemeni children with Down syndrome.

Materials and Methods:

The study sample comprised 101 children with Down syndrome attending special needs schools in Sana’a, Yemen. The calculus index (CI), plaque index (PI), and the gingival index (GI) were used to assess oral hygiene and gingival health status.

Results:

All subjects had gingivitis; the mean CI, PI, and GI scores were 0.58 ± 0.61, 1.45 ± 0.57, and 1.54 ± 0.64, respectively, with no significant difference found across gender. Stepwise linear regression analysis revealed that the best predictors in the descending order for CI were age and mother's education, and the best predictors for PI were IQ level, age, and father's education. Having severe mental retardation, older age, less educated parents were the most important predictors for poor gingival health status.

Conclusions:

These findings show that children with Down syndrome have poor oral hygiene and high levels of periodontal diseases. Hence, appropriate oral health education should be tailored to the needs of these children with the support of their teachers and parents.
