Long-term effectiveness of the midwifery initiated oral health-dental service program on maternal oral health knowledge, preventative dental behaviours and the oral health status of children in Australia.Acta Odontol Scanda
The Midwifery Initiated Oral Health-Dental Service was developed to train midwives to promote maternal oral health, and a large trial showed it substantially improved the oral health, knowledge and behaviours of pregnant women.
Evaluate the long-term effectiveness of the program (post-trial) on maternal oral health knowledge, dental behaviours, and early childhood caries in offspring.
A prospective cohort study involving 204 women and children 3-4 years (followed after trial) was conducted in Sydney, Australia from 2017 to 2019.
The program did not have a significant impact on the study measures. Mothers who received the program did have comparatively better knowledge around preventative behaviours to reduce early childhood caries and significantly more mothers were engaging in a key behaviour of using a cup to feed their child. Overall maternal oral health knowledge and level of education did have a protective effect on the dental decay of children. Higher knowledge and levels of education reduced the odds of having a dmft of one or more by over half (OR 0.473), and almost 80% (OR 0.212) respectively.
Although the MIOH-DS program was not effective, there is still value in exploring other complementary interventions to improve maternal oral health, especially for disadvantaged families. Future research should focus on co-designing an antenatal and postnatal oral health intervention and exploring its long-term impact on the oral health of children.

Leadership, work environment and caries prevention - what is good for the staff, is also good for the patients.Acta Odontol Scanda
Dental caries is a health problem that can be prevented. The aim of this study is to analyse if the quality of leadership, in Swedish Public Dental Health clinics, influences the extent to which patients with caries receive preventive care, and if any such effect is mediated through a collaborative work climate, clear role expectations and a low average level of burnout among staff.
The multilevel cross-sectional design includes work environment data from surveys of 75 general public dental clinics, register-based data on preventive measures provided to 5398 patients who received a dental filling due to a caries diagnosis, and patient demographics. Using a multilevel path analysis with logistic regression, we tested a model with one direct and three indirect pathways, controlling for the potential confounding effect of patient demographic factors.
Leadership quality, as assessed by the staff at the clinic, was associated with increased odds of patients with caries receiving prevention, controlling for patient demographic factors. Leadership quality was also positively related to a collaborative work climate, clear role expectations and a low average level of burnout among staff. Against expectations, however, no indirect effect from leadership quality on prevention through the other work environment factors was found.
In conclusion, the quality of leadership in Swedish Public Dental Health clinics was positively related to a good work environment for staff and to delivery of preventive care to patients experiencing caries.
Outcomes reporting in systematic reviews on Non-Surgical Root Canal Treatment: A scoping review for the development of a core outcome set.Endodontics
Studies related to non-surgical root canal treatment are amongst the most frequently performed clinical studies in endodontics. However, heterogeneity in reporting outcomes and lack of standardisation is a significant challenge to evidence synthesis and guideline development.
The aims of the present scoping review were to: a) identify outcomes reported in systematic reviews evaluating non-surgical root canal treatment; b) identify how and when the reported outcomes were measured; c) assess possible selective reporting bias in the included studies. The information obtained in this study should inform the development of a core outcome set (COS) for non-surgical root canal treatment.
Structured literature searches were performed to identify systematic reviews on non-surgical root canal treatments published in English between January 1990 and December 2020. Two reviewers undertook study selection and data extraction. Outcomes were categorized according to a healthcare taxonomy into five core areas (survival, clinical/physiological changes, life impact, resource use, and adverse events). The outcome measurement tools and length of follow-up was recorded.
75 systematic reviews were included, of which 40 included meta-analyses. Most reviews reported on physiological and clinical outcomes, primarily pain and/or radiographic assessment of periapical status, and a variety of measurement tools and scales were used. Few reviews focused on tooth survival, life impact, resources and adverse events. The heterogeneity among the reviews was large on all parameters. Less than 40% of the reviews assessed the risk of selective reporting.
Most studies reported on physiological and clinical outcomes, in particular pain and/or radiographic healing. Measurement tools, scales, thresholds, and follow-up periods varied greatly within each outcome, making comparison across studies complicated. Less than 40% of the reviews assessed risk of selective reporting, thus selective bias could not be ruled out. The presented information on reported outcomes, measurement tools and scales, and length of follow-up may guide the planning of future research and inform the development of a COS for non-surgical root canal treatment.
Successful management of gingival recession with interdental attachment loss using gingival unit grafts.Journal of Indian Society of
Gingival recession leads to root surface exposure devoid of periodontal attachment. Recession defects with interdental attachment loss (RT2, RT3), further increase the avascular area which is critical for survival of soft-tissue grafts. Nonsubmerged grafts such as free gingival grafts and gingival unit grafts (GUGs) rely primarily on plasmatic circulation from the recipient area during the initial stages of healing for its survival.
Nineteen isolated RT2 recession defects, in the mandibular anterior region, were treated using GUG. The clinical parameters of recession depth (RD), recession width (RW), interdental clinical attachment levels (iCAL) were measured at baseline. Percentage of mean root coverage (MRC) was calculated at 3 months and 6 months.
The percentage of mean root coverage (MRC) achieved at the end of 6 months was 81.79% ± 6.16%. Further, Simple linear regression analysis to predict MRC at 6 months using baseline RW revealed, for every 1 mm decrease in RW, the percentage of root coverage significantly increased by 5.25% (P = 0.04).
GUG can be used as an alternative treatment modality to achieve successful root coverage in RT2 recession defects. Baseline RW can be used to predict the outcome of root coverage at the end of 6 months.

Tooth loss and oral health-related quality of life among adult dental patients: A cross-sectional study.Indian Journal of Dental Research
- study setting and design
- materials and methods
- statistical analysis
Oral diseases seriously impair the quality of life (QoL) in a large number of individuals and they may affect various aspects of life.
To determine the relationship between tooth loss and oral health-related quality of life (OHRQoL) among adult dental patients.
A cross-sectional study was carried out among 296 adult dental patients aged 35-44 years attending Department of Oral Medicine and Radiology of Panineeya Institute of Dental Sciences and Hospital, Hyderabad, India.
Oral Health Impact Profile-14 (OHIP-14) was used to assess OHRQoL. Dentition status and periodontal status according to WHO criteria 2013 and position, number of teeth lost by Batista et al. (2014) tooth loss classification were assessed.
Mann-Whitney U test and analysis of variance were used to find prevalence and severity of OHIP-14 with tooth loss and logistic regression analysis to evaluate the association between OHIP-14 prevalence and severity based on variables.
Except for the subjects with history of previous dental visit, variables such as gender and reason for dental visit showed significant difference (P ≤ 0.05) with tooth loss. Males subjects, who visited dentist with a history of pain, presence of periodontal disease and tooth loss up to 12 teeth (score 3) emerged as significant predictors for OHIP-14 prevalence (OR = 6.7, OR = 1.13, OR = 3.31).
The study strongly evidenced that number and position of tooth loss had negative impacts on OHRQoL.
