Sleep bruxism and sleep respiratory disorders in children and adolescents: A systematic review.

OBJECTIVE: Sleep bruxism (SB) is a repetitive rhythmic and nonrhythmic activity. It can be a comorbid condition for other disorders, such as sleep breathing disorders (SBD). However, a clear causal link between these factors is yet to be established. Moreover, this relationship is even more unknown in children. Thus, this systematic review aimed to determine the relationship between SB and SBD in children and teenagers and consolidate the current knowledge about the possible association between both phenomena at the pediatric age. MATERIALS AND METHODS: Advanced searches were performed in five electronic databases with the last search updated on February 1, 2023. The methodological quality of the selected studies was analyzed using the quality assessment tool for experimental bruxism studies. RESULTS: Twenty-nine of 6378 articles were selected for detailed analyses. Most articles found a comorbid relationship between SB and SBD, though no study analyzed a temporary relationship. Due to the heterogeneity of the studies, a meta-analysis could not be performed. CONCLUSION: Despite the limitations of this systematic review, it can be concluded that there is an association between SB and SBD in children. However, the level of evidence is low.

Dental Implants Survival After Nasal Floor Elevation: A Systematic Review.

The aim of this work is to assess the clinical outcomes of implants placed after a nasal floor elevation procedure. A systematic review was conducted using 4 electronic databases: MEDLINE (PubMed), Cochrane Library, Directory of Open Access Journals, and Scopus, following the PRISMA (Preferred Reporting Items for Systematic Reviews) statement recommendations to answer the PICO (Population, Intervention, Comparison, Outcome) question: "In patients undergoing dental implant placement in the maxillary anterior region (P), Do implants placed after nasal floor elevation (I) have a different survival (O) from those implants placed without grafting procedures (C)? The study was pre-registered in PROSPERO (CRD42021229479). Included article quality was assessed using the "NIH quality assessment tool", "The Newcastle-Ottawa scale," and "JBI critical appraisal tools for case reports." Twelve articles were finally selected, including 151 patients and 460 implants. The weighted mean follow-up was 32.2 months, and the weighted survival rate after this period was 97.64% (range: 89.2%-100%). No statistical differences could be inferred between the treatments performed in 1- or 2-stage, following a lateral approach or a transcrestal approach or using different grafting materials. A great heterogeneity was found in study design and methodological aspects. For this reason, a quantitative analysis followed by meta-analysis was not possible. Within the limitations of this study, implants placed after a nasal floor elevation present a good survival and a low range of complications. In absence of randomized studies, the level of evidence was low, attending the GRADE (Grading of Recommendations, Assessment, Development, and Evaluations) system and based on the study quality level, the strength of evidence attending the SORT (Strength Of Recommendation Taxonomy) was B.

Implant-prosthetic treatment in patients with oral lichen planus: A systematic review.

AIMS: This review is aiming on identifying the ideal implant-prosthetic treatment design in patients with OLP. METHODS AND RESULTS: A systematic review was conducted using four electronic databases; Medline (PubMed), Cochrane library, DOAJ and SCOPUS, following the PRISMA statement recommendations to answer the PICO question: "which implant-prosthetic treatment design is most useful to ensure implant survival in OLP patients?". The study was pre-registered in PROSPERO (CRD 42020220102). Included articles quality was assessed using the "Newcastle-Ottawa scale" and the JBI critical appraisal tool for case series. No article was found specifically designed to analyze the prosthetic influence on implant survival in OLP patients. Despite, information about implant-prostheses in studies designed with other goals was compiled. Eight articles that involved 141 patients and 341 implants were finally selected. The weighted mean follow-up was 38 months and the weighted mean survival of the implants 98.9%. No statistical differences were observed between cemented or screw retained prostheses and the materials employed or the technology to manufacture the prostheses. CONCLUSION: The influence of prosthetic design on implant survival in OLP patients is still poorly understood, but important clinical recommendations can be drawn. The strength of evidence was grade 3b (CEBM) or low (GRADE).

Are mucous retention cysts and pseudocysts in the maxillary sinus a risk factor for dental implants? A systematic review / ¿Son riesgos los quistes y seudoquistes de retención mucosa en el seno maxilar factor para los implantes dentales? Una revisión sistemática

Background: Mucous retention cysts and pseudocysts of the maxillary sinus are benign lesions present in up to13% of adult patients. Different surgical approaches for sinus lift and dental implant placement in the presence ofthese lesions have been proposed.Material and Methods: A systematic review was performed following the PRISMA statement recommendationsto answer the PICO question: Does the aspiration or removal of mucous retention cysts/pseudocysts before or dur-ing sinus lifting and dental implant placing, affect the survival of the implants? The study was pre-registered inPROSPERO (CRD42020185528). Included articles quality was assessed using the “NIH quality assessment tool”and “The Newcastle-Ottawa scale”.Results: Previous literature in this field is scarce and with a low level of evidence. There are no randomized pro-spective studies. Only 19 studies were identified, being composed of 2 cohort studies and 17 case series/reports.These studies involved 182 patients with a previous history of mucous retention cyst or pseudocyst in 195 maxil-lary sinuses where 233 implants were placed. The mean age of the patients was 45.5 (range: 12-80 years); 122(67%) were male patients and 60 (33%) were female patients. The mean follow-up of the patients was 17.6 (range:4-90 months). Only two fail was reported. No differences were identified in relation to the surgical approach or inrelation to the removal/aspiration of the sinus lesion (prior to or simultaneous to sinus grafting) or not.Conclusions: The level of evidence was grade 4 according to the CEBM and further studies are needed to confirmthis observations, but with the available data, dental implants placement after sinus lift procedure in patients withmucous retention cysts and pseudocysts seems to be safe and present high survival regardless on the removal ofthe lesion or not.(AU)

Synchronous oral squamous cell carcinoma and extramedullary plasmacytoma of the tonsil.

Extramedullary plasmacytoma (EP) is characterized by a neoplastic proliferation of plasma cells in a soft tissue site and arises particularly in the head and neck region. We report here an unusual case of maxillary sinus EP coexisting with oral squamous cell carcinoma (SCC) in a patient without any identified environmental risk or predisposing factors. The maxillary sinus mass proved to be radioresistant, with distant metastasis of EP in the tonsil and thoracic skin. The patient subsequently received chemotherapy and showed no evidence of recurrence at 6 months' follow-up. To the best of our knowledge, this is the first case reported demonstrating synchronous occurrence of oral SCC and EP arising in oral cavity.

Microvascular free tissue transfer for tongue reconstruction after hemiglossectomy: a functional assessment of radial forearm versus anterolateral thigh flap.

PURPOSE: The purpose of this study was to evaluate tongue function and donor site morbidity in patients with oral cancer surgically treated and reconstructed with radial or anterolateral thigh free flaps. PATIENTS AND METHODS: Twenty patients underwent primary reconstruction after hemiglossectomy between January 2002 and June 2004. Ten patients were reconstructed using a free forearm flap and the remaining with an anterolateral thigh flap. Eight patients on each group underwent postoperative radiotherapy (average, 60 Gy). All of them were followed postoperatively to determine after 6 months their functional outcome as it related to speech, deglutition, tongue mobility, and donor site morbidity. The intelligibility, deglutition, and tongue mobility were each scored on a scale ranging from 1 to 7 by an independent investigator. Data were analyzed by the 2-tail Mann-Whitney U test. RESULTS: No differences in mean speech intelligibility, tongue mobility, or deglutition mean scores were seen between radial forearm flap and anterolateral thigh flap (P > .05). In all anterolateral thigh flap-treated cases, the donor site was closed directly and no complications were seen. However, in all forearm flaps donor site closure was carried out with skin grafts and dorsal forearm splinting was applied for 1 week postoperatively. In 4 cases a partial skin graft failure was observed and donor sites healed for second intention. CONCLUSION: Anterolateral thigh flap, with its versatility in design, long pedicle with a suitable vessel diameter, and low donor site morbidity, could be the ideal flap for hemiglossectomy defect reconstruction.
