Cepillos interdentales, de la teoría a la práctica. Revisión de literatura e indicaciones clínicas / Interdental toothbrushes, from theory to practice: a review of the literature and clinical indications

Los cepillos interproximales son una herramienta de higiene interdental que tiene variadas indicaciones y múltiples beneficios. Pacientes con enfermedad periodontal, con papilas que no llenan el espacio interdentario, portadores de aparatología ortodóncica, prótesis fija o de implantes entre otros casos, pueden beneficiarse con su utilización. El presente artículo tiene como objetivo dar una orientación de su uso clínico basado en la evidencia científica disponible. Los resultados apoyan su utilización en combinación con el hilo dental para la prevención y tratamiento de las enfermedades bucales más prevalentes, con un efecto marcado sobre el control del biofilm y la inflamación gingival (AU)

Interproximal brushes are an interdental hygiene tool with diverse indications that have, multiple benefits. Among other uses, they are indicated in patients with periodontal disease, with papillae that do not fill the interdental space, patients with orthodontic appliances, fixed prosthesis or implant-supported prosthesis. The aim of this article is provide guidance on their clinical use based on the available evidence. The results support their use in combination with dental floss for preventing and treating the most prevalent oral diseases, with a significant effect on biofilm control and gingival inflammation (AU)

Theoretical and hands-on guidance from dental hygienists promotes good oral health in elderly people living in nursing homes, a pilot study.

OBJECTIVES: Oral health in nursing homes for elderly is often unsatisfactory, and oral health education to nursing staff has not shown sufficient results why there is need for novel approaches. The aim of the study was to trial a new oral healthcare educational programme and to evaluate the effects on residents' oral health. In addition, attitudes among the nursing staff in the intervention nursing home were explored. METHODS: In a controlled clinical trial, two comparable nursing homes were randomly assigned for intervention or control. Interventions included weekly theoretical and hands-on guidance from dental hygienists on oral hygiene procedures and discussions on oral care routines. The residents' oral health, measured by the Revised Oral Assessment Guide (ROAG), dental plaque and gingival bleeding were evaluated at baseline and after 3 months. Attitudes among the staff to oral health care were measured at the intervention nursing home. RESULTS: Revised Oral Assessment Guide gums and lips scores showed a tendency to decrease in the intervention group, but remained high in the control group. Plaque levels improved significantly after intervention, and a trend towards less gingival bleeding was observed. The intervention nursing staff seemed to be more aware of their own limitations concerning oral health care after intervention and valued more frequent contact with dental services to a greater extent. CONCLUSIONS: The oral healthcare situation for elderly people today is so complex that theoretical education at the group level regarding different aspects of oral health is not sufficient. Individual hands-on guidance by dental hygienists on a regular basis in everyday care may be a new approach.

Prospective Clinical Study of Zirconia Full-coverage Restorations on Teeth Prepared With Biologically Oriented Preparation Technique on Gingival Health: Results After Two-year Follow-up.

OBJECTIVES: To evaluate the clinical behavior of one-piece complete-coverage crowns and fixed partial dentures (FPDs) on teeth with vertical preparation without finish line biologically oriented preparation technique (BOPT). METHODS AND MATERIALS: This prospective study included 52 patients requiring treatment with restorations in the esthetic region: 74 crowns and 27 FPDs. The sample included a total of 149 teeth that were prepared vertically without finish line. The sample was divided into two groups: one-piece crowns and FPDs, all with zirconia cores, feldspathic ceramic veneer, and a 0.5-mm prosthetic finish line of zirconia. All procedures were carried out at the University of Valencia from 2013 to 2014. The following parameters were evaluated over a two-year follow-up: oral hygiene, periodontal state, gingival thickening, gingival margin stability, the presence of complications, and restoration survival rate. Patient satisfaction with treatment was assessed by means of a visual analogue scale (VAS). RESULTS: Two years after treatment, 80.5% of treated teeth remained free of gingival inflammation and bleeding. Mean gingival thickening was 0.41 ± 0.28 mm for one-piece crowns and 0.38 ± 0.36 mm for FPDs. Gingival margin stability was 100%, but 2% of the sample presented biological complications. The VAS patient satisfaction scores were eight out of a maximum score of 10. CONCLUSIONS: Two years after treatment, vertical preparation without finish line produces gingival thickening, margin stability, and optimal esthetics. Neither crowns nor FPDs presented any mechanical complications.

Effect of an oral healthcare program on gingival health status in rural areas of South Korea.

INTRODUCTION: The purpose of this study was to analyze the effects of an oral health care program administered at rural public health subcenters on oral hygiene status and bleeding on probing (BOP) scores among Korean rural residents older than 40 years. METHODS: Residents older than 40 years living in two rural areas were allocated randomly by order of visit into an intervention group (n=23) and control group (n=23). Changes in plaque and BOP score were analyzed between the groups using repeated-measures ANOVA. Hierarchical multiple regression analysis was conducted to identify factors affecting changes in BOP score. RESULTS: The BoP score decreased by 22.87 in the intervention group and 0.27 in the control group between baseline and the eighth week (p<0.001). Multiple regression analysis showed that the change in BoP score (ΔBoP score) increased significantly with an increase in the reduction of the plaque (PHP) index (ΔPHP index) (t=-2.174, p<0.05) and increased significantly more in the intervention group than in the control group (t=2.143, p<0.05). CONCLUSIONS: Professional care and continuous oral health education for 8 weeks prior to scaling among adults older than 40 years living in rural environments resulted in a change in oral health behaviors and a substantial reduction in gingival bleeding.

Gingival condition associated with two types of orthodontic fixed retainers: a meta-analysis.

BACKGROUND: The maintenance of gingival health around orthodontic fixed retainers (FRs) is difficult and different designs have been proposed. OBJECTIVE: The goal of this systematic review was to analyse whether FR designs that allow unobstructed interproximal flossing, compared with the ones that do not, improve gingival parameters. SEARCH METHODS: Detailed individual database search strategies for Cochrane Library, 'Latin' American and 'Caribbean' Health Sciences Literature, PubMed, Scopus, and Web of Science were developed. Grey literature was also considered. SELECTION CRITERIA: Clinical trials and cross-sectional studies that compared two types of FRs (plain and waved) were included and evaluated. DATA COLLECTION AND ANALYSIS: Study selection, data extraction, and risk of bias (RoB) assessment were performed individually and in duplicate. The methodology quality was assessed using the MAStARI RoB tool. RESULTS: Four studies met the inclusion criteria, and all presented moderate RoB. While two of those studies found a statistically significant difference in gingival parameters, the other two did not report differences. A meta-analysis was conducted based on two of the selected studies, which performed evaluations of plaque index (PI) and calculus index (CI). The results revealed no differences on PI between wave FR and plain FR of 0.46 (0.24 to 0.69) and no differences on CI of 0.12 (-0.10 to 0.33). Regarding comfort, no clear differences were identified. CONCLUSIONS: There is not enough scientific evidence to support or not an association between FR design and gingival health, flossing frequency, or patient comfort.

Cell Attachment Following Instrumentation with Titanium and Plastic Instruments, Diode Laser, and Titanium Brush on Titanium, Titanium-Zirconium, and Zirconia Surfaces.

PURPOSE: The aim of this study was to evaluate the surface characteristics and gingival fibroblast adhesion of disks composed of implant and abutment materials following brief and repeated instrumentation with instruments commonly used in procedures for implant maintenance, stage-two implant surgery, and periimplantitis treatment. MATERIALS AND METHODS: One hundred twenty disks (40 titanium, 40 titaniumzirconium, 40 zirconia) were grouped into treatment categories of instrumentation by plastic curette, titanium curette, diode microlaser, rotary titanium brush, and no treatment. Twenty strokes were applied to half of the disks in the plastic and titanium curette treatment categories, while half of the disks received 100 strokes each to simulate implant maintenance occurring on a repetitive basis. Following analysis of the disks by optical laser profilometry, disks were cultured with human gingival fibroblasts. Cell counts were conducted from scanning electron microscopy (SEM) images. RESULTS: Differences in surface roughness across all instruments tested for zirconia disks were negligible, while both titanium disks and titaniumzirconium disks showed large differences in surface roughness across the spectrum of instruments tested. The rotary titanium brush and the titanium curette yielded the greatest overall mean surface roughness, while the plastic curette yielded the lowest mean surface roughness. The greatest mean cell counts for each disk type were as follows: titanium disks with plastic curettes, titanium-zirconium disks with titanium curettes, and zirconia disks with the diode microlaser. CONCLUSION: Repeated instrumentation did not result in cumulative changes in surface roughness of implant materials made of titanium, titanium-zirconium, or zirconia. Instrumentation with plastic implant curettes on titanium and zirconia surfaces appeared to be more favorable than titanium implant curettes in terms of gingival fibroblast attachment on these surfaces.

Toothbrushing procedure in schoolchildren with no previous formal instruction: variables associated to dental biofilm removal / Procedimiento de cepillado en escolares sin previo entrenamiento formal: variables asociadas al barrido del biofilm dental

The aim of this study was to establish the association betweenfeatures regarding brushing procedure performed by school-children without previous formal training and the effectivenessof biofilm removal. Out of a population of 8900 6- and 7-year-old schoolchildrenin Buenos Aires City, 600 children were selected from schoolslocated in homogeneous risk areas. Informed consent wasrequested from parents or guardians and formal assent wasobtained from children themselves. The final sample consistedof 316 subjects. The following tooth brushing variables wereanalyzed: toothbrush-gripping, orientation of active part ofbristles with respect to the tooth, type of movement applied,brushing both jaws together or separately, including all 6sextants and duration of brushing. The level of dental biofilmafter brushing was determined by O’Leary’s index, acceptablecut-off point = 20%. Four calibrated dentists performedobservations and clinical examinations. Frequency distribution,central tendency and dispersion measures were calculated.Cluster analyses were performed; proportions of variables foreach cluster were compared with Bonferroni’s correction andOR was obtained. The most frequent categories were: palm gripping (71.51%);perpendicular orientation (85.8%); horizontal movement(95.6%); separate addressing of jaws (68%) and inclusion ofall 6 sextants (50.6%). Mean duration of brushing was 48.78 ±27.36 seconds. 42.7% of the children achieved an acceptablebiofilm level. The cluster with the highest proportion of subjectswith acceptable post-brushing biofilm levels (p<0.05) differedsignificantly from the rest for the variable “inclusion of all 6 sextants in brushing procedure”. OR was 2.538 (CI 95%1.603 – 4.017). Inclusion of all six sextants could be a determinant variable forthe removal of biofilm by brushing in schoolchildren, and shouldbe systematized as a component in oral hygiene education.

Se evaluaron los conocimientos y se valoró el estado de salud bucal antes y después de la intervención.Resultados: al inicio de la intervención el 95 por ciento de las pacientes estaba afectada por enfermedad gingival; después de aplicada la intervención educativa se incrementaron los conocimientos en las embarazadas y la enfermedad gingival se redujo, afectando a un menor número de pacientes, el 87,5 por ciento.Conclusiones: se logró reducción de la enfermedad gingival con la aplicación de acciones de educación para la salud, pero no fue todo lo efectiva que se esperaba(AU)

Background: it is necessary to educate people to reduce the incidence of gum disease, especially in priority groups such as pregnant women. The increase of knowledge in this respect represents one of the pillars for a better oral health.Objective: to evaluate the effectiveness of an educational intervention to modify the state of the oral health in pregnant women seen at 3 de Octubre Teaching Dental Clinic.Methods: an educational intervention was carried out with pregnant women seen at the dental clinic herein mentioned, between June, 2012 and June, 2014. The study population consisted of 80 patients. The variables measured were: oral hygiene, using the Lōe and Silness index for oral hygiene; and level of knowledge, using the scale of good, fair and poor. An educational intervention on educational issues was performed, with participation didactic games such as puzzles, crosswords, dominoes and chats. Knowledge was assessed and the state of oral health before and after the intervention was evaluated.Results: at the beginning of the intervention a 95 percent of the patients were affected by gum disease; after applying the educational intervention knowledge by pregnant women increased and gum disease was reduced, affecting a lower number of patients, 87,5 percent.Conclusions: gum disease reduction was achieved with the implementation of actions of health education, but it was not as effective as expected(AU)

'Healthy gums do matter': A case study of clinical leadership within primary dental care.

The Health and Social Care Act 2012 heralded wide reaching reforms intended to place clinicians at the heart of the health service. For NHS general dental practice, the conduits for this clinical leadership are the NHS England local professional networks. In Greater Manchester, the local professional network has developed and piloted a clinician led quality improvement project: 'Healthy Gums DO Matter, a Practitioner's Toolkit'. Used as a case study, the project highlighted the following facilitators to clinical leadership in dentistry: supportive environment; mentoring and transformational leadership; alignment of project goals with national policy; funding allowance; cross-boundary collaboration; determination; altruism; and support from wider academic and specialist colleagues. Barriers to clinical leadership identified were: the hierarchical nature of healthcare, territorialism and competing clinical commitments.

Esthetic, occlusal, and periodontal rehabilitation of anterior teeth with minimum thickness porcelain laminate veneers.

Ceramic veneers of minimum thickness provide satisfactory esthetic outcomes while preserving the dental structure. Dental ceramics can both improve the esthetic appearance and reestablish the strength and function of teeth. In worn anterior teeth, functional surfaces, for example, anterior and lateral guidance, can be restored effectively. The characteristics of dental ceramics, such as color stability and mechanical and optical properties, make this material a good choice for indirect restorations, especially when optimum function and esthetics are required. This clinical report presents an occlusal, periodontal, and restorative solution with minimum thickness glass ceramic veneers for worn anterior teeth with multiple diastemas.

Powered versus manual toothbrushing for oral health.

BACKGROUND: Removing dental plaque may play a key role maintaining oral health. There is conflicting evidence for the relative merits of manual and powered toothbrushing in achieving this. This is an update of a Cochrane review first published in 2003, and previously updated in 2005. OBJECTIVES: To compare manual and powered toothbrushes in everyday use, by people of any age, in relation to the removal of plaque, the health of the gingivae, staining and calculus, dependability, adverse effects and cost. SEARCH METHODS: We searched the following electronic databases: the Cochrane Oral Health Group's Trials Register (to 23 January 2014), the Cochrane Central Register of Controlled Trials (CENTRAL) (The Cochrane Library 2014, Issue 1), MEDLINE via OVID (1946 to 23 January 2014), EMBASE via OVID (1980 to 23 January 2014) and CINAHL via EBSCO (1980 to 23 January 2014). We searched the US National Institutes of Health Trials Register and the WHO Clinical Trials Registry Platform for ongoing trials. No restrictions were placed on the language or date of publication when searching the electronic databases. SELECTION CRITERIA: Randomised controlled trials of at least four weeks of unsupervised powered toothbrushing versus manual toothbrushing for oral health in children and adults. DATA COLLECTION AND ANALYSIS: We used standard methodological procedures expected by The Cochrane Collaboration. Random-effects models were used provided there were four or more studies included in the meta-analysis, otherwise fixed-effect models were used. Data were classed as short term (one to three months) and long term (greater than three months). MAIN RESULTS: Fifty-six trials met the inclusion criteria; 51 trials involving 4624 participants provided data for meta-analysis. Five trials were at low risk of bias, five at high and 46 at unclear risk of bias.There is moderate quality evidence that powered toothbrushes provide a statistically significant benefit compared with manual toothbrushes with regard to the reduction of plaque in both the short term (standardised mean difference (SMD) -0.50 (95% confidence interval (CI) -0.70 to -0.31); 40 trials, n = 2871) and long term (SMD -0.47 (95% CI -0.82 to -0.11; 14 trials, n = 978). These results correspond to an 11% reduction in plaque for the Quigley Hein index (Turesky) in the short term and 21% reduction long term. Both meta-analyses showed high levels of heterogeneity (I(2) = 83% and 86% respectively) that was not explained by the different powered toothbrush type subgroups.With regard to gingivitis, there is moderate quality evidence that powered toothbrushes again provide a statistically significant benefit when compared with manual toothbrushes both in the short term (SMD -0.43 (95% CI -0.60 to -0.25); 44 trials, n = 3345) and long term (SMD -0.21 (95% CI -0.31 to -0.12); 16 trials, n = 1645). This corresponds to a 6% and 11% reduction in gingivitis for the Löe and Silness index respectively. Both meta-analyses showed high levels of heterogeneity (I(2) = 82% and 51% respectively) that was not explained by the different powered toothbrush type subgroups.The number of trials for each type of powered toothbrush varied: side to side (10 trials), counter oscillation (five trials), rotation oscillation (27 trials), circular (two trials), ultrasonic (seven trials), ionic (four trials) and unknown (five trials). The greatest body of evidence was for rotation oscillation brushes which demonstrated a statistically significant reduction in plaque and gingivitis at both time points. AUTHORS' CONCLUSIONS: Powered toothbrushes reduce plaque and gingivitis more than manual toothbrushing in the short and long term. The clinical importance of these findings remains unclear. Observation of methodological guidelines and greater standardisation of design would benefit both future trials and meta-analyses.Cost, reliability and side effects were inconsistently reported. Any reported side effects were localised and only temporary.

[Ridge preservation with synthetic nanocrystalline hydroxyapatite reduces the severity of gingival invaginations-a prospective clinical study]. / Alveolenerhalt mit einem nanopartikulärem Hydroxylapatit verringert den Ausprägungsgrad von Gingivaduplikaturen - eine prospektive klinische Studie.

BACKGROUND AND OBJECTIVE: Gingival invaginations develop after tooth extraction and subsequent orthodontic space closure. Aetiological factors and long-term effects of gingival invaginations on oral health are nearly unknown. In addition, preventive or therapeutic strategies are rare. This prospective clinical study employing the split mouth technique was performed to investigate the effect of extraction socket augmentation with a synthetic nanocrystalline hydroxyapatite (NanoBone(®) Artoss, Rostock, Germany) on the incidence and degree of gingival invaginations. MATERIAL AND METHODS: A total of 10 orthodontic patients with need for symmetric premolar extractions offering a total of 28 extractions were included in this trial. The study plan provided one extraction site to be augmented with synthetic nanocrystalline hydroxyapatite (NanoBone(®)), the other served as control. After primary wound healing, space closure was performed under defined biomechanical conditions. After space closure was accomplished, occurrence and degree of gingival invaginations as well as probing depths of the adjacent teeth mesial and distal to the extractions were determined and dental radiographs were taken. RESULTS: The degree of gingival invaginations and probing depths mesial and distal of the extraction were significantly reduced on NanoBone(®) augmented extraction sites. In addition, 70% of the radiographs revealed translucent and hyperdense areas on the intervention side after space closure. Apical root resorption was found in 2 patients on both the NanoBone(®) side and the control side. CONCLUSION: Ridge preservation with NanoBone(®) appeared to reduce the severity of gingival invaginations. Further investigation on long-term effects is mandatory to eliminate the appearance of adverse effects.

Influence of clinical experience on oral health attitude and behaviour of dental students attending a Nigerian university.

OBJECTIVE: To evaluate the self-reported oral health attitudes and behaviour among the clinical dental students and to compare the influence of clinical experience on oral health attitudes and behaviour among dental students at the different clinical years in the University of Benin using the modified Hiroshima University Dental Behavior Inventory (HU-DBI). METHODS: The study involved 156 clinical dental students from the University of Benin, Benin City, Nigeria. Demographic data were obtained for age and gender from 4th, 5th and 6th year clinical students. A modified English version of HU-DBI survey consisted of 22 items with dichotomous responses (yes-no) was used in this study. Descriptive statistics was performed for age and clinical level of education. Chi-square text was applied to the percentages of responses. Tamhane's T2 post-hoc multiple comparison for pairwise comparison of the three clinical levels of students was done to determine the differences. Test significance was set at P < 0.05. RESULTS: The response rate was 87.2%. The mean age of the respondents was 26.2 + 2.4 years. A total of 62 (39.7%) respondents were females and 94 (60.3%) males. Statistically significant differences were found among the various clinical levels of dental students for previous visit to the dentist office, visiting the dentist unless there is toothache, brushing the teeth twice daily and the prevention of gum disease with tooth brushing alone. CONCLUSION: There was improvement in the dental students' oral health behaviour and attitudes with increasing level of dental education.
