OBJECTIVE
in patients with Parkinson's Disease (PD), oral health can be affected by motor and non-motor symptoms and/or medication use. Therefore, the aim was to systematically review the literature on oral health and associated factors of oral health in PD patients.
DESIGN
a literature search was performed from inception up to April 5th, 2023. Original studies that assessed oral health-related factors in PD patients and were written in English or Dutch, were included.
RESULTS
11276 articles were identified, of which 43 met the inclusion criteria (quality range poor-good). A higher prevalence of dental biofilm, bleeding/gingivitis, pocket depth (≥4 mm), tooth mobility, caries, and number of decayed missing filled teeth/surfaces was found in PD patients than in controls. However, no difference between both groups was found when analysing edentulism and wearing dentures. Poor oral health of PD patients was associated with a longer disease duration, higher disease severity, and more prescribed medications.
CONCLUSIONS
oral health of PD patients is worse than that of healthy individuals. It is associated with the duration and severity of PD and medication use. Therefore, we advise regular appointments with oral health care professionals, with an important focus on prevention.

Review
BACKGROUND
The ESE previously published quality guidelines for endodontic treatment in 2006; however, there have been significant changes since not only in clinical endodontics but also in consensus and guideline development processes. In the development of the inaugural S3-level clinical practice guidelines (CPG), a comprehensive systematic and methodologically robust guideline consultation process was followed in order to produce evidence-based recommendations for the management of patients presenting with pulpal and apical disease.
AIM
To develop an S3-level CPG for the treatment of pulpal and apical disease, focusing on diagnosis and the implementation of the treatment approaches required to manage patients presenting with pulpitis and apical periodontitis (AP) with the ultimate goal of preventing tooth loss.
METHODS
This S3-level CPG was developed by the ESE, with the assistance of independent methodological guidance provided by the Association of Scientific Medical Societies in Germany and utilizing the GRADE process. A robust, rigorous and transparent process included the analysis of relevant comparative research in 14 specifically commissioned systematic reviews, prior to evaluation of the quality and strength of evidence, the formulation of specific evidence and expert-based recommendations in a structured consensus process with leading endodontic experts and a broad base of external stakeholders.
RESULTS
The S3-level CPG for the treatment of pulpal and apical disease describes in a series of clinical recommendations the effectiveness of diagnosing pulpitis and AP, prior to investigating the effectiveness of endodontic treatments in managing those diseases. Therapeutic strategies include the effectiveness of deep caries management in cases with, and without, spontaneous pain and pulp exposure, vital versus nonvital teeth, the effectiveness of root canal instrumentation, irrigation, dressing, root canal filling materials and adjunct intracanal procedures in the management of AP. Prior to treatment planning, the critical importance of history and case evaluation, aseptic techniques, appropriate training and re-evaluations during and after treatment is stressed.
CONCLUSION
The first S3-level CPG in endodontics informs clinical practice, health systems, policymakers, other stakeholders and patients on the available and most effective treatments to manage patients with pulpitis and AP in order to preserve teeth over a patient's lifetime, according to the best comparative evidence currently available.

Review
BACKGROUND
Bruxism is a repetitive masticatory muscles activity whose definition is being thoroughly reviewed in recent years. As in adults, two different forms of bruxism exist in children, namely awake and sleep bruxism. Scarcity of data, however,still persists about paediatric bruxism and no clear consensus has been developed. Therefore, the current review overviews the literature on bruxism in children tries to outline the state of art about this condition METHODS: Bruxism affects from 5% to 50% of the worldwide paediatric population. Sleep disturbances, parafunctional habits and psycho-social factors emerged to be the most likely associated factors with paediatric bruxism. Bruxism is characterised by several signs and symptoms variously combined, such as tooth wear and fractures, teeth impressions on soft tissues, temporomandibular disorders, headaches, behavioural and sleep disorders. About diagnosis, the most reliable tool in children remains the report of teeth grinding by parents or caregivers which must be accompanied by oral interview and accurate clinical examination. Electromyography and sleep polysomnography, albeit suitable in the diagnostic process, are not easy-to-use in children and are not strongly recommended. Currently, no evidence exists to support any kind of therapeutic options for bruxism in children. Management should be based on the identification of the underlying condition and conservative approaches are recommendable.
CONCLUSION
Notwithstanding the high prevalence, several aspects need to be further assessed in paediatric bruxism. Parental reports are still the most suitable diagnostic tool and conservative approaches are recommended in the management. Bruxism should be considered through a biopsychosocial model, and sleep, personality traits, stress and headaches are the factors towards whom research questions must be addressed to improve diagnosis and management.

Review
This scoping review aims to summarize the available evidence on strategies employed in preventing caries in patients with molar incisor hypo-mineralization (MIH). MIH refers to an enamel defect involving opacities, and sometimes post-eruptive degradation due to enamel porosity; resulting in outcomes ranging from a mild atypical caries to severe coronary destruction. A systematic review was conducted for literature in PubMed, Cochrane Library, Epistemonikos and Literatura Latinoamericana y del Caribe en Ciencias de la Salud (LILACS). The search was aimed at studies published between January 2010 and February 2022. Data were independently selected and extracted. 989 studies were found from the systematic search and 8 studies met the eligibility criteria. Most studies evaluated remineralization and cariogenic risk, both of which are crucial elements in caries prevention, as well as decreased sensitivity. The included studies investigated fluoride varnish, dental sealants, giomers, casein, and Icon as preventative methods for dental caries. Several methods for preventing dental caries in paediatric patients with MIH exist, but more research is needed to determine their effectiveness and safety. Any preventive intervention should consider the etiological aspects of the disease, the risk of caries, the type and extent of lesions, hypersensitivity level and patient's age. Collaboration between patients and carers is critical for disease diagnosis and caries prevention.

Review
Dental caries is a serious multifactorial oral disease that causes demineralization of the tooth's hard tissues and affects more than half of the world's population. The objective of this exploratory systematic review was to determine the prevalence of dental caries in Mexican children and adolescents, as well as related factors such as sex, nutritional status, type of dentition, education, living conditions, socioeconomic level, and the type of demographic area. The eligibility criteria to be considered were observational studies whose sample included Mexicans 0-15 years of age in which the prevalence or an index of dental caries had been evaluated. Eligible studies were identified through the search carried out in 6 databases and manual search, without publication time restriction. Fifty-four studies were found that met the eligibility criteria. In these included studies it was observed that, in the last decades, the prevalence of caries in Mexican children and adolescents exhibits a tendency to decrease this disease. In the 1980s, caries prevalences of up to 92.8% were reported; between 1990-1999, the highest reported prevalence was 97%; from 2000-2009, the highest reported prevalence was 95%; from 2010 to 2019 the highest prevalence was 94.6%; and from 2020 and 2021, prevalences of up to 88.5% were reported. Although there has been a decrease in the prevalence of caries in Mexican children, this disease continues to be linked to biological, behavioral and socioeconomic determinants.

Review
Neurofilaments (NFs) are the most abundant component of mature neurons, that interconnect with actin and microtubules to form the cytoskeleton. Specifically expressed in the nervous system, NFs present the particularity within the Intermediate Filament family of being formed by four subunits, the neurofilament light (NF-L), medium (NF-M), heavy (NF-H) proteins and α-internexin or peripherin. Here, we review the current knowledge on NF proteins and neurofilaments, from their domain structures and their model of assembly to the dynamics of their transport and degradation along the axon. The formation of the filament and its behaviour are regulated by various determinants, including post-transcriptional (miRNA and RBP proteins) and post-translational (phosphorylation and ubiquitination) modifiers. Altogether, the complex set of modifications enable the neuron to establish a stable but elastic NF array constituting the structural scaffold of the axon, while permitting the local expression of NF proteins and providing the dynamics necessary to fulfil local demands and respond to stimuli and injury. Thus, in addition to their roles in mechano-resistance, radial axonal outgrowth and nerve conduction, NFs control microtubule dynamics, organelle distribution and neurotransmission at the synapse. We discuss how the studies of neurodegenerative diseases with NF aggregation shed light on the biology of NFs. In particular, the and genes are mutated in Charcot-Marie-Tooth (CMT) disease, the most common inherited neurological disorder of the peripheral nervous system. The clinical features of the CMT forms (axonal CMT2E, CMT2CC; demyelinating CMT1F; intermediate I-CMT) with symptoms affecting the central nervous system (CNS) will allow us to further investigate the physiological roles of NFs in the brain. Thus, NF-CMT mouse models exhibit various degrees of sensory-motor deficits associated with CNS symptoms. Cellular systems brought findings regarding the dominant effect of NF-L mutants on NF aggregation and transport, although these have been recently challenged. Neurofilament detection without NF-L in recessive CMT is puzzling, calling for a re-examination of the current model in which NF-L is indispensable for NF assembly. Overall, we discuss how the fundamental and translational fields are feeding each-other to increase but also challenge our knowledge of NF biology, and to develop therapeutic avenues for CMT and neurodegenerative diseases with NF aggregation.

Journal of Dentistry Nov 2023Literature was systematically reviewed to identify salivary characteristics and their association with tooth wear. (Meta-Analysis)
Meta-Analysis Review
OBJECTIVE
Literature was systematically reviewed to identify salivary characteristics and their association with tooth wear.
DATA
A protocol was developed a priori (PROSPERO CRD42022338590). Established systematic review methods were used for screening, data extraction, and synthesis. Risk of bias and the certainty of evidence were assessed using the JBI tools and GRADE, respectively. Direct and indirect association between tooth wear and salivary components and characteristics were assessed.
SOURCES
MEDLINE, Embase, SCOPUS, Web of Science, CINAHL, and additional sources were searched.
STUDY SELECTION
Studies reporting salivary characteristics in patients with tooth wear or models thereof were included. Animal and in-vitro studies and case reports were excluded.
RESULTS
One-hundred eleven studies were included. Qualitative analyses showed a negative association between tooth wear and salivary pH and flow rate in many studies. The higher the study size the higher the chances that an association with pH and flow rate was found. Xerostomia, buffer capacity and salivary consistency/viscosity had also some degree of association with tooth wear in fewer studies. Associations with the 39 salivary components were scarcer. Random effects meta-analyses (7 studies) showed that pH levels in stimulated whole saliva were lower in patient with tooth wear compared to controls (-0.07 [-0.10 to -0.04]). However, there was not enough evidence to establish a quantitative association with flow rate. The general risk of bias was unclear and the certainty of evidence was low or very low. A large diversity of methodologies limited the inclusion of all studies in quantitative synthesis.
CONCLUSION
From all potential risk factors, stimulated whole saliva pH showed a negative association, both quantitatively and qualitatively with tooth wear, indicating potential usefulness of pH monitoring in these patients. Moreover, associations between flow rate and tooth wear were observed qualitatively. However, in both cases the risk of bias was mostly unclear, and the certainty of evidence was low. No causal associations could be observed.
CLINICAL SIGNIFICANCE
Tooth wear is a prevalent condition that may lead to functional or esthetic impairments and pain. Knowing the potential risk factors like salivary pH or flow rate and their dynamics could be relevant during tooth wear monitoring and to intervene accordingly, especially in conditions like gastroesophageal reflux disease.

(1) Background: Both tooth loss and diabetes have high global prevalence, and both have a significant influence on patients' general health and quality of life. Previous research has indicated a possible connection between tooth loss and diabetes, but it has been unclear whether tooth loss has an effect on the development of diabetes and how it affects it. We aim to investigate the relationship between insulin resistance (IR) and tooth loss and examine how the systemic immune-inflammation index (SII) level and diet quality mediate it. (2) Methods: The cross-sectional study data were obtained from the National Health and Nutrition Examination Survey (NHANES). After describing and comparing baseline data, we used regression models to evaluate the relationship between IR and tooth loss, diet quality and tooth loss and IR, SII and tooth loss and IR. Furthermore, we applied bootstrapping to test the mediation effect of diet quality and SII between tooth loss and IR. Diet quality is reflected by the HEI (Healthy Eating Index)-2015 score. (3) Results: The total number of subjects included was 8197, with 3861 individuals belonging to the IR group (HOMA-IR ≥ 2.5) and 4336 in the non-IR group (HOMA-IR < 2.5). In the model with all covariates adjusted, tooth loss in the fourth quartile was found to be positively correlated with an increase in HOMA-IR (OR = 1.301; 95% confidence interval (CI) = [1.102, 1.537]; < 0.001) compared to the first quartile; tooth loss in the fourth quartile correlated with the HEI-2015 score compared to the first quantile (β = -0.121, 95% CI = [-4.839, -2.974], < 0.001); and the highest number of tooth loss was found to have a significant effect on SII (β = 0.032; 95%CI = [1.777, 47.448]; < 0.05). Compared to average diet quality, best diet quality acts as a safeguard against elevated HOMA-IR (OR = 0.776; 95% CI = [0.641, 0.939]; < 0.01); inadequate diet quality is a risk factor (OR = 1.267; 95%CI = [1.138, 1.411]; < 0.001) conversely. Meanwhile, it can be seen that compared with the first quantile of SII, the highest score is significantly correlated with the higher incidence of IR (OR = 1.363; 95%CI = [1.179, 1.575]; < 0.001). Diet quality and SII played a partial mediating role in the relationship between HOMA-IR and tooth loss, and the mediating effect ratio for the total effect value was 4.731% and 4.576%, respectively. The mediating effect of SII and diet quality in the association of the relationship between HOMA-IR and tooth loss both was 0.003 (95%CI = [0.001, 0.004]). (4) Conclusions: Our study revealed the relationship between IR and tooth loss, and further explored the mediating role of SII and diet quality between the number of missing teeth and IR, emphasizing that improving diet quality and reducing SII can effectively prevent and treat IR and related diseases. It provides new theoretical support for the study of IR mechanisms and new ideas and approaches to deal with related diseases.

BACKGROUND
Charcot-Marie-Tooth disease is the most common inherited peripheral neuropathy and many patients with Charcot-Marie-Tooth are women of childbearing age. Guidelines for managing pregnancy in Charcot-Marie-Tooth are lacking.
AIMS
To assess the impact of pregnancy on Charcot-Marie-Tooth and how Charcot-Marie-Tooth affects pregnancy, delivery and postnatal care.
METHODS
A retrospective questionnaire exploring disease course during pregnancy, delivery, pregnancy complications, anaesthetic management and puerperium was administered to 92 patients with Charcot-Marie-Tooth and related disorders.
RESULTS
Worsening of Charcot-Marie-Tooth symptoms were reported in 37% of pregnant patients which resolved after delivery in half of the patients. No significant increase in pregnancy, delivery and anaesthetic complications were observed and the type of delivery did not significantly differ from the normal population.
CONCLUSIONS
While these results are reassuring, ideally an international prospective study should be done to confirm these results and to develop practice guidelines on the management of pregnancy in Charcot-Marie-Tooth.
