RESUMO
OBJECTIVE: To evaluate whether there is a relationship between occlusion and body posture evaluated using a stabilometric platform. METHODS: Observational studies that analyzed the relationship between dental occlusion (changes in mandibular position and/or dental malocclusion) and body posture evaluated with a stabilometric platform in patients older than 13 years without orthodontic or orthopedic intervention and systemically healthy were considered eligible for inclusion. PubMed, EMBASE, Science Direct, LILACS, and Google Scholar databases were searched to obtain articles published from September 2019 up to March 2020. RESULTS: Twelve articles met the inclusion criteria, of which 66.7% showed a relationship between dental occlusion and body posture, and 33.3% found no relationship. The marked heterogeneity between studies did not allow data to be combined for meta-analyses. CONCLUSION: For the mandibular positions, the postural changes were mainly in the mediolateral direction, while in the malocclusions, they were in the anteroposterior direction.

BACKGROUND: One of the most important complications of radiotherapy (RT) for head and neck cancer (HNC) is osteoradionecrosis (ORN) of the jaws, arising mainly from tooth extractions. Thus, the present study aimed to evaluate the efficacy of leukocyte- and platelet-rich fibrin (L-PRF) in preventing ORN following tooth extraction in post-irradiated HNC patients, as well as other postoperative complications. MATERIAL AND METHODS: 23 patients previously submitted to conventionally fractionated 3D-conformational RT for HNC underwent atraumatic tooth extractions with perioperative antibiotic therapy. Besides, they were randomly assigned to receive L-PRF clots to fill and cover the extraction sockets (n=11, Test Group) or not (n=12, Control Group). A visual analog scale was used to quantify postoperative pain on the 3rd and 7th days. For ORN diagnosis, patients were clinically assessed for up to 180 days. Other postoperative complications (edema, alveolitis, suture dehiscence, continuous bleeding, and oroantral communication) were also evaluated within this period. RESULTS: No case of ORN or another surgical complication was observed and there were no differences in the postoperative pain scores between the groups on the 3rd and 7th days. CONCLUSIONS: L-PRF did not seem to provide any additional benefits than those achieved by the combination of the surgical and drug protocols used for tooth extractions in the post-irradiated HNC patients.

The aim of this study was to assess the survival rate of titanium implants placed in irradiated jaws. MEDLINE, EMBASE, and CENTRAL were searched for studies assessing implants that had been placed in nongrafted sites of irradiated patients. Random effects meta-analyses assessed implant loss in irradiated versus nonirradiated patients and in irradiated patients treated with hyperbaric oxygen (HBO) therapy. Of 1,051 potentially eligible publications, 15 were included. A total of 10,150 implants were assessed in the included studies, and of these, 1,689 (14.3%) had been placed in irradiated jaws. The mean survival rate in the studies ranged from 46.3% to 98.0%. The pooled estimates indicated a significant increase in the risk of implant failure in irradiated patients (risk ratio: 2.74; 95% confidence interval: 1.86, 4.05; p < .00001) and in maxillary sites (risk ratio: 5.96; 95% confidence interval: 2.71, 13.12; p < .00001). Conversely, HBO therapy did not reduce the risk of implant failure (risk ratio: 1.28; 95% confidence interval: 0.19, 8.82; p = .80). Radiotherapy was linked to higher implant failure in the maxilla, and HBO therapy did not improve implant survival. Most included publications reported data on machined implants, and only 3 studies on HBO therapy were included. Overall, implant therapy appears to be a viable treatment option for reestablishing adequate occlusion and masticatory conditions in irradiated patients.

OBJECTIVES: The objective of this study was to evaluate the long-term effect of an oral hygiene and prevention programme on caries and periodontal disease in a group of children attended at a private periodontal practice. METHODS: A total of 50 systemically healthy children, 25 males and 25 females, 03-13years old, were invited to join a long-term plaque control programme. All children had no caries and had no evidence of clinical bone loss. The participants were selected amongst children whose parents (mother, father or both) were treated of gingivitis, aggressive periodontitis or chronic periodontitis in a private periodontal practice. Subjects were separated in groups according to their parents' periodontal diagnosis, i.e., gingivitis, aggressive periodontitis or chronic periodontitis. The following outcomes were evaluated: a) probing depth, b) plaque (PI) and gingival (GI) indexes. The plaque control programme applied consisted of a regular maintenance regime at 6-to 12-month interval with an experienced periodontist. RESULTS: In total 30 subjects fulfilled the 20-year period of maintenance. The mean recall frequency was 6.4 (± 3.1) months, and the mean PI and GI were 0.4 (± 0.3) and 0.3 (± 0.3) respectively. The average rate of caries lesions was 1.0 (± 1.4). None of the patients exhibited clinical or radiographic evidences of alveolar bone loss, and no tooth was lost by caries. In addition, there were no statistically significant differences between groups (P>0.05). CONCLUSIONS: Adequate oral hygiene measures and periodic professional plaque control led to low levels of dental plaque, gingivitis and caries lesions.

Bony exostosis (BE) is described as a benign localised overgrowth of bone of unknown aetiology. Buccal bony exostosis (BBE) development secondary to soft tissue graft procedures has been reported in a small number of cases. The dental literature describes BBE development also at sites where free gingival grafts (FGG) have been used to increase the amount of gingiva. The following case series describes BBE development at nine sites (five cases) at which FGG was performed to increase the width of the attached gingiva. The presence of exostoses has been recognised during postoperative visits. Histological examination revealed osseous enlargements compatible with the diagnosis of exostoses at two re-entry procedures. In conclusion, based on previous reports, periosteal trauma, eg fenestration, seems to be the main aetiologic agent associated with the development of BBE in areas where FGG were placed.

Um estudo comparativo em gengiva humana foi realizado utilizando duas tecnicas de sutura: uma classica interrompida interproximal e outra continua com duas agulhas em alca. As diferencas clinicas observadas baseiam-se na melhor adaptacao obtida com o retalho e nas melhores condicoes de trabalho determinadas pela maior rapidez e maior facilidade na remocao do cimento cirurgico conseguidas com a tecnica de sutura continua. A analise da saude gengival no periodo de tres meses, alem de outros aspectos clinicos estudados nao puderam demonstrar diferencas apreciaveis existentes entre estas duas tecnicas. Os resultados histologicos demonstraram um mesmo padrao de reparacao, se bem que maturacao tecidual mais precoce e menor grau de inflamacao foram observados no lado em que utilizamos a tecnica continua com duas agulhas
