The Randomized Shortened Dental Arch Study: Tooth Loss
The evidence concerning the management of shortened dental arch (SDA) cases is sparse. This multi-center study was aimed at generating data on outcomes and survival rates for two common treatments, removable dental prostheses (RDP) for molar replacement or no replacement (SDA). The hypothesis was that the treatments lead to different incidences of tooth loss. We included 215 patients with complete molar loss in one jaw. Molars were either replaced by RDP or not replaced, according to the SDA concept. First tooth loss after treatment was the primary outcome measure. This event occurred in 13 patients in the RDP group and nine patients in the SDA group. The respective Kaplan-Meier survival rates at 38 months were 0.83 (95% CI: 0.74-0.91) in the RDP group and 0.86 (95% CI: 0.78-0.95) in the SDA group, the difference being non-significant
Childhood dental injuries: a resiliency model of adaptation
Background.
There is a paucity of research examining
how children and their families adapt to
traumatic dental injuries.
Aim. This study examined how clinical and psychosocial
factors influence adaptation to this oral
stressor using a theoretical framework of resiliency
and adaptation.
Design.
Children with traumatised permanent
teeth, who were attending a UK dental hospital,
completed questionnaires at baseline and at a
6 month follow-up. Child questionnaires assessed
coping styles, social support, and quality of life
outcomes. Parents were also asked to complete
questionnaires, which assessed previous stressors/
strains on the family, social support, healthcare
satisfaction, and family impacts. Data related to
the child’s dental injury were collected from clinical
notes. Structural equation modelling and
regression analyses were employed to analyse
data.
Results.
One hundred and eight children and 113
parents participated at baseline. Children’s gender,
coping style, social support, and family functioning
significantly predicted children’s oral health related
quality of life. Parents’ satisfaction with
their children’s dental care significantly predicted
parental quality of life outcomes. Children’s close
friend support and healthcare satisfaction
remained significant predictors of positive outcomes
at follow-up.
Conclusions.
The findings revealed important psychosocial
factors that influence child and family
adaptation to childhood dental trauma
A randomized clinical trial evaluating the efficacy of the sandwich bone augmentation technique in increasing buccal bone thickness during implant placement. II. Tomographic, histologic, immunohistochemical, and RNA analyses
ObjectivesThis study aimed to evaluate the biologic and structural phenotypes of the bone regenerated via the sandwich bone augmentation (SBA) technique, on buccal implant dehiscence defects.Material and MethodsTwenty‐six patients with one buccal implant dehiscence defect each were randomly assigned to two groups. Both groups received a standardized amount of mineralized cancellous and cortical allogenic bone graft. In the test group, a bovine pericardium membrane was placed over the graft, while no membrane was placed in the control group. After 6 months of healing, a bone core biopsy of the regenerated bone was harvested and processed for histologic, immunohistochemical, mRNA, and micro‐computed tomography (μCT) analyses. Of the 26 bone core biopsies, only six cores from the test group and six cores from the control group were suitable for the analysis.ResultsBone volume (BV) in the test group was maintained, but tissue maturation appeared to be delayed. In contrast, tissue maturation appeared to be completed in the control group, but BV was compromised. Micro‐CT analysis showed that specimens from the control group were more structured and mineralized compared with those from the test group. Histologic analysis showed more residual graft particles scattered in a loose fibrous connective tissue matrix with sparse bone formation in the test group, while the control group showed obvious vital bone formation surrounding the residual graft particles. Positive periostin (POSTN), sclerostin, and runt‐related transcription factor‐2 (RUNX2) immunoreactivities were detected in both the control and test groups. However, tartrate‐resistant acid phosphatase (TRAP) positive was mostly noted in the control group. There were significant differences in POSTN, RUNX2 and VEGF expressions between the test and control groups.ConclusionThese findings indicated that the SBA technique was an effective method in preserving adequate structural volume while promoting new vital bone formation. Use of the collagen barrier membrane has successfully maintained the volumetric dimensions of the ridge but might have slowed down the complete maturation of the outermost layer of the grafted site.Peer Reviewedhttp://deepblue.lib.umich.edu/bitstream/2027.42/113698/1/clr12481-sup-0001-Checklist.pdfhttp://deepblue.lib.umich.edu/bitstream/2027.42/113698/2/clr12481.pd
