Occlusal schemes for complete dentures may influence clinical performance and patient satisfaction. Patient characteristics such as alveolar ridge shape and height also influence choice of scheme. There are several schemes to choose from including bilateral balanced, lingualised, canine guidance, group function, and monoplane. A number of studies and reviews have been conducted but a consensus on an ideal occlusal scheme if lacking.

The aim of this overview was to assess the methodological quality and summarize the scientific evidence from secondary studies about the influence of occlusal schemes on the clinical performance of and patient satisfaction with complete dentures.

Methods
A protocol for the review was registered with PROSPERO. Searches were carried out in the Cochrane Library, PubMed, Embase, LILACS, Scopus, the Web of Science, PROSPERO, Google Scholar and Open Science Framework databases. Systematic reviews that included randomized or non-randomized clinical trials evaluating conventional complete dentures with different occlusion schemes on clinical performance and patient satisfaction were considered. Two reviewers independently selected studies and extracted data with disagreements being resolved by a third reviewers. The AMSTAR 2 tool was used to assess the quality of the reviews. The effect of each occlusal scheme in comparison with others was summarized and classified as positive, neutral, negative, or inconclusive based on the conclusions of the systematic review concerning clinical performance and patient satisfaction outcomes.

Results
10 systematic reviews were included.
All 10 reviews included randomised controlled trials (RCTs) 5 also included prospective studies, 2 included other systematic reviews, 2 included clinical studies involving partial dentures or implants.
No meta-analyses were presented in any of the 10 reviews.
Confidence in the reviews was rated as critically low for 7 reviews, low for 2 reviews and moderate for one review using the AMSTAR 2 tool.
Summary suggested that occlusal schemes may influence objective and subjective clinical performance and patients' satisfaction.
Conclusions
The authors concluded: –

.occlusal schemes might interfere with the clinical performance of and patient satisfaction with complete dentures. Lingualized, bilateral balanced, and canine guidance are preferred compared with monoplane occlusion, but lingualized occlusion tends to show better results in some reviews. However, the results should be carefully considered because of the low quality of the systematic reviews included.

This overview of reviews of the influence of occlusal schemes on the clinical performance of and patient satisfaction with complete dentures included 10 systematic reviews. While the findings suggest that occlusal schemes might interfere with the clinical performance the results should be carefully considered because of the low quality of the systematic reviews included.

Does social support predict increased use of dental services in older men?

paythelady.61 shared this article with you from Inoreader

Abstract

Background

Past research on social support and dental visits in older people has been limited by cross-sectional design, limited social support dimensions, and non-representative samples.

Methods

Data came from men with natural teeth completing Waves 3 and 4 of the Concord Health and Ageing in Men Project (CHAMP) in Sydney, Australia. The relationship between social support at Wave 3 (2011-2012) and at least one dental visit per year at Wave 4 (2014-2016) was examined by Poisson regression. Social support was measured by structural (marital status, living arrangements, family support, social interaction) and functional (social support satisfaction) domains.

Results

There were 673 men analysed. Structural and functional social support were not associated with the pattern of usual dental visits five years later in univariable or multivariable analyses. The only consistent significant factor was income source, with older men who had other sources of income more likely to regularly visit the dentist than older men solely reliant on the pension for income (PR: 1.31, 95% CI: 1.13 – 1.52).

Conclusions

We found no differences in the pattern of usual dental visits between older men with different levels and types of social support. For older Australian men, income source seems to be the most important determinant of regular dental visits. © 2022 Australian Dental Association

Sclerostin in Periodontal Ligament: Homeostatic Regulator in Biophysical Force‐Induced Tooth Movement

paythelady.61 shared this article with you from Inoreader

Abstract

Aim

This study elucidates the role of sclerostin in periodontal ligament (PDL) as a homeostatic regulator in biophysical force-induced tooth movement (BFTM).

Materials and Methods

BFTM was performed in rats, followed by microarray, immunofluorescence, in situ hybridization, and real-time PCR for detection and identification of the molecules. The periodontal space was analyzed via micro-computed tomography. Effects on osteoclastogenesis and bone resorption were evaluated in mouse bone marrow-derived cells. In vitro human PDL cells were subjected to biophysical forces.

Results

In the absence of BFTM, sclerostin was hardly detected in the periodontium except the PDL and alveolar bone in the furcation region and apex of the molar roots. However, sclerostin was upregulated in the PDL in vivo by adaptable force, which induced typical transfiguration without changes in periodontal space as well as in vitro PDL cells under compression and tension. In contrast, the sclerostin level was unaffected by heavy force, which caused severe degeneration of the PDL and narrowed periodontal space. Sclerostin inhibited osteoclastogenesis and bone resorption, which corroborates the accelerated tooth movement by the heavy force.

Conclusions

Sclerostin in PDL may be a key homeostatic molecule in the periodontium and a biological target for the therapeutic modulation of BFTM.

Use of transoral carbon dioxide laser for supraglottic web from caustic ingestion in a 13 year old

paythelady.61 shared this article with you from Inoreader
A 13 year old male was referred to the Department of Otorhinolaryngology due to unsuccessful decannulation. At 2 years of age, patient accidentally ingested a caustic liquid alkali and underwent emergency tracheostomy, exploratory laparotomy, and tube gastrectomy. 11 years after, patient was seen at the outpatient department for decannulation. On nasopharyngolaryngoscopy, a supraglottic stenosis with a central 1-mm opening was visualized. Patient underwent transoral carbon dioxide laser excision of supraglottic stenosis.

Modification of an extended total temporomandibular joint replacement (eTMJR) classification system

paythelady.61 shared this article with you from Inoreader
The aims of this paper were to validate a modification of an extended total temporomandibular joint replacement (eTMJR) classification system and develop a classification schematic for ease of reference. High volume TMJ surgeons were asked to score 20 separate eTMJR devices using the updated classification system and inter-rater variability was calculated. Using the modified classification system developed, a Conger's kappa (k) coefficient of 0.53 was returned, suggesting moderate to good levels of agreement.
