Relatively few empirical studies of pediatric chewing interventions have been published in the psychology literature. The purpose of this paper was to systematically review chewing interventions within the applied behavior analysis literature. We identified a small, but growing, behavior analytic literature demonstrating the effectiveness of various multicomponent treatment packages to teach and improve chewing skills. Future researchers should consider a range of participant characteristics, including results of oral motor assessments, explore a more extensive definition of chewing to target the complex nature of chewing as well as component skills, and examine the necessary and sufficient components of chewing interventions along with the potential benefits of multidisciplinary interventions.

Review
Current methods to detect eating behavior events (i.e., bites, chews, and swallows) lack objective measurements, standard procedures, and automation. The video recordings of eating episodes provide a non-invasive and scalable source for automation. Here, we reviewed the current methods to automatically detect eating behavior events from video recordings. According to PRISMA guidelines, publications from 2010-2021 in PubMed, Scopus, ScienceDirect, and Google Scholar were screened through title and abstract, leading to the identification of 277 publications. We screened the full text of 52 publications and included 13 for analysis. We classified the methods in five distinct categories based on their similarities and analyzed their accuracy. Facial landmarks can count bites, chews, and food liking automatically (accuracy: 90%, 60%, 25%). Deep neural networks can detect bites and gesture intake (accuracy: 91%, 86%). The active appearance model can detect chewing (accuracy: 93%), and optical flow can count chews (accuracy: 88%). Video fluoroscopy can track swallows but is currently not suitable beyond clinical settings. The optimal method for automated counts of bites and chews is facial landmarks, although further improvements are required. Future methods should accurately predict bites, chews, and swallows using inexpensive hardware and limited computational capacity. Automatic eating behavior analysis will allow the study of eating behavior and real-time interventions to promote healthy eating behaviors.

This study aimed to evaluate the effectiveness of conventional occlusal analysis in contrast with digital occlusal analysis in natural dentition. Occlusal analysis allows the identification of normal and abnormal occlusal contact points that alter the craniomandibular cervical system. We searched for articles with keywords [[dental occlusion]], [[natural dentition]], [[occlusal adjustment]], [[Immediate Complete Anterior Guidance Development]] [[mastication]], [[bite force]], [[premature contact]], [[occlusal balance]] [[articulating paper]]], [[spray]], [[Occlusal contacts]], and [[bite strength]]. They were considered observational , odds ratio and case control studies. We found 189 items. After evaluating the abstracts and full texts of the articles, 10 papers met the inclusion criteria. It was found that occlusal analysis allows the identification of the relationship between poor occlusion and the sensitivity of the teeth due to occlusal trauma, which is also related to temporomandibular joint pain in dynamic occlusion. The contacts of greater strength were observed in nonfunctional cusps, 48%, without ruling out the functional cusps, 24%. Despite being the universal method of occlusal control to date, the use of joint paper, remains subjective compared to the digital occlusal control device. Posture is considered directly related to occlusal trauma and temporomandibular disorders; without proper occlusal analysis, a clear diagnosis of the patient's joint condition cannot be obtained. Digital occlusal analysis is more objective than traditional occlusal analysis.

Review
INTRODUCTION
Treatment for oral cancer can impair oral functions such as mastication, which may negatively affect quality of life (QoL). In this review, an overview is provided of masticatory ability in patients treated for oral cancer.
METHODS
The PubMed (MEDLINE), Embase and Cochrane databases were systematically searched for scientific literature on masticatory ability in relation to QoL in patients treated for oral cancer. Studies were included when oral cancer treatment was provided, and the University of Washington Quality of Life (UW-QoL) questionnaire was used. Risk of bias (MINORS) was independently assessed by two authors.
RESULTS
The PubMed (MEDLINE), Embase and Cochrane search yielded 575 unique records of which 111 were assessed full text, and 27 studies were included. The UW-QoL mastication scores ranged from 31.9 to 97.4. There was a wide variety in methodology, patient groups, tumour site, treatment and assessment moment, to such a degree that outcome scores are difficult to compare.
CONCLUSION
The wide variety in studies exploring health-related QoL in relation to mastication in oral cancer patients prevents the identification of possible relations between treatment, masticatory ability and QoL. Our findings underline the limitations in currently available literature and indicate the necessity for more comparable research.

Review
The pigmentation of the fungiform papillae of the tongue is a rare idiopathic condition in which only the fungiform papillae appear hyperpigmented. In the absence of any reviews on the subject, we conducted a systematic review of the aetiopathogenesis and pathophysiology of pigmented fungiform papillae (PFP) of the tongue, including its demographic and histopathological features, trying to outline a possible aetiology. The preferred reporting items for systematic reviews and meta-analyses (PRISMA) was performed using PubMed, Scopus, EMBASE databases and manual searches, for publications between January 1974 and July 2022. Inclusion criteria were case reports defining patients' characteristics, their general medical and dental conditions, histopathological and/or immunohistochemical findings, all with a final definitive diagnosis of PFP. Overall, 51 studies comprising 69 cases of PFP which included histopathological descriptions were reviewed. Prominent features consisted of hyperpigmentation of melanocytes, melanophages, chromatophores, and a lymphocytic infiltrate in the subepidermal area of the fungiform papillae. On special staining, PFP contained melanin, not iron or hemosiderin. On immunohistochemistry, immune-reactive CD3+ T lymphocytes, S-100 and Sox10, but non-immune-reactive melan-A intraepithelial melanocytes were noted in some studies. The presence of hyperpigmented melanocytes and melanophages, with non-immune-reactive melan-A, suggests that PFP are a benign and physiological form of pigmentation. The inflammatory infiltrates described in some papillary lesions could possibly be due to traumatic events during mastication. Nevertheless, the true reasons for the hyperpigmentation of the fungiform papillae are as of yet elusive, and remain to be determined.

Review
STATEMENT OF PROBLEM
Temporomandibular disorders (TMDs) affect the muscles of mastication, the temporomandibular joint, and associated structures. They are generally classified as muscular or articular and are the main cause of pain in the orofacial region, eventually causing psychological problems. However, the real burden of psychological disorders is unknown.
PURPOSE
The purpose of this systematic review and meta-analysis was to assess the prevalence of psychological disorders in patients with TMDs.
MATERIAL AND METHODS
The study was conducted through a bibliographic search carried out without initial limit until July 2021 in the following electronic databases: MEDLINE/PubMed, Scopus, and PsycINFO. Clinical observational studies investigating depression and somatization in patients with TMD diagnosed by the Diagnostic Research for Temporomandibular Disorders (RDC/TMD) criteria in muscular, articular, and disc disorders were included. A descriptive analysis of the included studies and a meta-analysis for the prevalence data were performed for the synthesis of evidence.
RESULTS
A total of 2320 studies were found, of which 48 complete articles were assessed for eligibility and 22 were included in the analysis. The general prevalence of depression and moderate and severe somatization in patients diagnosed with TMD was estimated at 43.0% (95% confidence interval (CI), 36.0% to 50.0%) and 60.0% (95% CI 52.0 - 67, 0%). The average overall score for depression was estimated at 0.92 (95% CI, 0.69-1.15), being classified as moderate depression. The average overall score for somatization was estimated at 1.09 (95% CI, 0.81-1.36), being classified as severe somatization. All analyses showed high heterogeneity (I>90%). Based on the quality assessment, 80.9% of studies included in the review had low to moderate risk of bias.
CONCLUSIONS
Patients with TMDs who seek clinical care show a high prevalence of depression and somatization.

Meta-Analysis
BACKGROUND
Oral health is a key factor of overall health and closely associated with well-being and quality of life. Mastication is one the most important oral functions and may deteriorate with aging. Evidence on association between masticatory dysfunction and frailty in the literature is scarce and not coherent.
METHODS
A search strategy was developed to conduct a systematic review of the literature in PubMed, CINAHL, and AMED in accordance with the PRISMA 2020 guidelines. We searched for studies published in 2000 or later that examined associations between self-reported masticatory dysfunction and frailty risk. The reference lists of the relevant articles were reviewed for additional studies. We calculated pooled odds ratios (OR) of association between self-reported masticatory dysfunction and the risk of frailty by fixed-effects meta-analysis. The Joanna Briggs Institute Critical Appraisal Checklist was used to assess risk of bias. Publication bias was assessed by visually inspecting a funnel plot.
RESULTS
A total of 285 studies were identified by the literature search. Among 5 studies selected for this review, 4 cross-sectional studies including a total of 7425 individuals were used for meta-analysis. The pooled results by a fixed-effects model showed that there was a significant association between self-reported masticatory dysfunction and frailty risk (pooled OR = 1.83, 95%CI = 1.55-2.18, p<0.00001). There was no evidence of publication bias observed.
CONCLUSIONS
This systematic review and meta-analysis highlighted pooled cross-sectional evidence that community-dwelling older people who report masticatory dysfunction are significantly more likely to be frail than those who do not. The limitations of this study are: inclusion of only cross-sectional studies, no gold standard to measure masticatory functions, self-reported information on masticatory function, and the limited number of included studies. More longitudinal studies are warranted for further understanding of the causal pathways and elucidate underlying mechanisms. Registration: PROSPERO CRD42021277173.

Review
OBJECTIVES
This systematic review aims to investigate the effect of different preparation designs on the marginal fit and fracture strength of ceramic occlusal veneers.
MATERIALS AND METHODS
Based on the PICO question and the search terms, an electronic search was performed in Google Scholar, PubMed (MEDLINE), Scopus, Cochrane Library, Web of Science, Science Direct, Wiley, Ovid, and SAGE for articles published up to July 2022. After including English in vitro studies that evaluated posterior ceramic occlusal overlays at the posterior with ceramic restorations by following the PRISMA statement, the extracted data was tabulated. The methodological quality of the included studies was evaluated. Risk of bias assessment was done independently by two authors using the modified MINORS scale.
RESULTS
About 3138 search results were screened, of which 22 were selected due to their titles. Twenty-one full-text articles were assessed for eligibility. Seventeen in-vitro studies were finalized for the extraction of quantitative data. All 17 articles had a low risk of bias and were retained. The influencing items for evaluating the research were different in most studies; therefore, qualitative synthesis of the results was feasible. They generally included preparation design, material thickness, depth of preparation in the tooth, internal divergence angle, and finish line. Meta-analysis was not done due to heterogeneity of preparation types and evaluation methods. Results revealed that fracture resistance of occlusal veneers is higher than normal mastication force, and it is sufficient to prepare the occlusal surface, use a self-etching primer for bonding, and an acceptable minimum ceramic thickness. The marginal discrepancy of occlusal veneers is clinically acceptable. However, this systematic review faces some limitations due to the lack of in vivo studies, different preparation designs in included studies, different follow-ups, and lack of comprehensive explanations in articles.
CONCLUSIONS
The preparation design of occlusal veneers influences both marginal adaptation and fracture resistance. Various preparation designs are proven to have clinically acceptable fracture strength and marginal adaptation.

Meta-Analysis Review
PURPOSE
The present systematic review and meta-analysis aimed to summarise the current information on the masticatory function of stroke patients.
METHODS
Four electronic databases (Medline, Embase, CINAHL and Web of Science) were searched for relevant observational studies and clinical trials (up to Jun 2021) on the masticatory function of stroke patients. Two reviewers independently performed study selection and quality assessments (using JBI Critical Appraisal Checklist). Meta-analysis was conducted for the comparison of bite force and masticatory performance using standardised mean difference (SMD). Of the 3837 records identified, nine studies, corresponding to 11 papers and 302 participants, were included in the analysis.
RESULTS
The maximum bite force of stroke patients was significantly lower than that of the healthy individuals (SMD -0.52, 95% CI: -0.95 to -0.08, P = .02). There was no significant difference between the ipsi-lesional and the contra-lesional sides of the same stroke patient (SMD 0.13, 95% CI: -0.14 to 0.39, P = .34). Stroke patients had lower masticatory performance than healthy people (SMD -0.97, 95% CI: 0.57 to 1.37, P < .00001), and the contra-lesional side was worse than the ipsi-lesional side. Electromyographic analysis indicated that muscle activation of stroke patients was poorer than the healthy individuals, and stroke patients seem to exhibit dysfunction in the recruiting and firing of motor units.
CONCLUSIONS
Stroke patients have lower maximum bite force and masticatory performance than healthy people, with masticatory performance being the most affected.

Review
OBJECTIVES
We have attempted to characterize the clinical presentations and management of infratemporal fossa abscesses with the goal of improving awareness and promoting earlier diagnosis and treatment for this rare condition.
METHODS
an extensive systematic search was performed through Pubmed/Medline, CINAHL (EBSCOhost), and Web of Science. Two authors screened out studies by abstracts, and a third resolved any conflicts. The remaining studies were assessed by full-text assessment, leaving 43 studies for data extraction.
RESULTS
sixty-seven patients were included from the final 43 studies. The patients were predominantly male (56.7%), and the average age of patients was 44.3 years (standard deviation (SD) 19.8 years). Risk factors most commonly odontogenic, whether the etiology was through tooth extraction (n = 30, 44.8%) or infection (n = 17, 25.4%). Symptoms on presentation included pain (n = 40, 83.3%), swelling (n = 39, 81.3%), and trismus (n = 36, 75.0%). Twenty-two (32.8%) patients were managed with intraoral incision and drainage (I&D), 18 (26.9%) with extraoral I&D. After treatment, 45 of the 48 (93.8%) patients from the case reports and series were deemed to have achieved complete resolution.
CONCLUSIONS
Infratemporal fossa abscesses are rare, but they may be associated with serious neurologic and systemic complications. Although prompt diagnosis paramount in avoiding these sequelae, patients often experienced delays in diagnosis. Surgical drainage and extended antibiotic therapy is recommended.
