Longevity of complete dentures: A systematic review and meta-analysis

Statement of problemPatients and clinicians are aware of the efficacy and benefits of complete dentures, but evidence regarding their longevity is limited.PurposeThe purpose of this systematic review was to examine the literature describing the longevity of complete dentures and to review variations in longevity by denture type and duration of follow-up.Material and methodsFour electronic databases were searched by using key terms: MEDLINE, CINAHL (EBSCO), Dentistry and Oral Sciences Databases, and The Cochrane Library. Studies meeting the inclusion criteria were reviewed according to an established protocol and data extracted. Reference lists of identified studies were examined. Risk of bias was assessed by using the AXIS tool. Weighted means and weighted standard deviations were calculated. Pooled complete denture failure proportions were estimated by using random effects models based on the DerSimonian and Laird method.ResultsThe search yielded 21 607 unique abstracts, of which 273 met the inclusion criteria. Assessment of the full-text articles reduced this number to 42. Of these, 24 studies were rated as having low risk of bias and 18 as very low. The weighted mean ±standard deviation longevity of maxillary complete dentures was 10.3 ±3.8 years, of mandibular dentures was 8.6 ±2.6 years, and of both maxillary and mandibular dentures was 10.8 ±4.7 years. The pooled failure proportion for complete dentures observed for 2 years or less was 0.05 (95% confidence interval [CI]: 0.00-0.10), 5 to 6 years was 0.12 (95% CI: 0.08-0.16), and 10 years or more was 0.41 (95% CI: 0.28-0.53).ConclusionsComplete dentures, fabricated primarily in university settings, were found to have a weighted mean ±standard deviation longevity of 10.1 ±4.0 years. The failure rate of these prostheses increased with denture age, and the longevity of maxillary dentures was greater than that of mandibular dentures.     

Development of a conceptual model of oral health for malocclusion patients

Objectives:To provide an empirical test of the applicability of Locker''s conceptual model of oral health for malocclusion patients, and to suggest alternative models of the effect of malocclusion on well-being.Materials and Methods:Data from a survey of 323 adolescents attending for orthodontic treatment were analyzed to develop a new oral health model for malocclusion patients. Oral health–related quality of life (OHRQoL) was measured using the 14-item Oral Health Impact Profile; malocclusion was measured using the Dental Health Component (DHC) of the Index of Orthodontic Treatment Need (IOTN). Using structural equation modeling, the relationship between conceptual domains in Locker''s model was explored and three models of their interrelationship tested for goodness of fit.Results:Fit indexes for Locker''s model indicated that it did not fit the data well. Therefore, a modified model was developed to incorporate additional paths between other levels to better fit the data. The best fit was provided by a model in which the direct effects of malocclusion on pain, discomfort, and handicapping—and the direct effect of pain on disability—were removed. A direct effect of functional limitation on disability was allowed. The modified Oral Health Impact Profile model proved to be a good fit to the data (root mean square error of approximation  =  0.069).Conclusion:The pathways identified in Locker''s (1988) conceptual model of oral health may not be appropriate for describing the relationships between OHRQoL constructs in individuals with malocclusion. An alternative model is proposed.     

Inferior glenohumeral joint dislocation with greater tuberosity avulsion

Inferior glenohumeral dislocation is the least common type of glenohumeral dislocations. It may be associated with fractures of the adjacent bones and neurovascular compromise. It should be treated immediately by close reduction. The associated neuropraxia usually recovers with time. Traction-counter traction method is commonly used for reduction followed by immobilization of the shoulder for three weeks. Here, we report a case of inferior glenohumeral joint dislocation with greater tuberosity fracture with transient neurovascular compromise and present a brief review of the literature.
