Correlation between vegetarian diet and oral health: a systematic review.

OBJECTIVE: Nutrition plays a significant role in preserving the balance of the human body. Considering each person's particular characteristics, diet can directly and indirectly alter the body's immune response. The purpose of this study is to draw attention to the connection between a vegetarian diet and its impact on oral health. MATERIALS AND METHODS: To determine the connection between a vegetarian diet and dental health, a search of the literature was conducted on the PubMed, Scopus, and Web of Science databases. English language and a publication year between January 1, 2013, and March 1, 2023, were the inclusion criteria for the search. RESULTS: There were 167 articles in total that addressed the subject of interest, and 18 of them were chosen for qualitative analysis. CONCLUSIONS: This study suggests that a vegetarian diet may alter oral health, namely periodontal health, tooth erosion, and oral microbiome. Even if the data collected prevents the effect of a vegetarian diet on oral health from being confirmed, this study acts as a starting point for future, more focused research.

Prosthetic rehabilitation of maxillary lateral incisors agenesis using dental mini-implants: a multicenter 10-year follow-up.

OBJECTIVES: Implants are used to replace congenitally missing lateral incisors but often the space across the alveolar crest is too narrow to permit their use. This multicenter study (Dental Clinic of the University of Foggia, Odontostomatology Clinic of the University of L'Aquila) evaluated the efficacy of mini-implants in cases of maxillary lateral incisor agenesis with severe osseous atrophy in 10-year follow-up. MATERIALS AND METHODS: Forty-seven mini-implants have been inserted in 35 patients affected by lateral incisors agenesis (23 single and 12 bilateral ageneses). All patients underwent orthodontic opening of the space of the upper lateral incisors. After the insertion of the implants, the immediate, non-functional loading, positioning of crowns, presence of pain during percussion and mini-implant function, horizontal and vertical movement when a force of 5 N was applied, ridge loss, and plaque index have been evaluated 1 month after loading, 1 year after loading, and then every 5 years in the following 10 years. Little's test was used to evaluate the assumption that data of loss to follow-up implants are missing completely at random (MCAR) and that a complete-case scenario could be adopted. Wilcoxon test was carried out to look statistically significant differences between the various parameters resulting in the complete-case scenario and those assumed for the worst scenario. The software R (v. 3.6.1, 2019) was employed to perform the statistical analysis. RESULTS: The results obtained over 10 years range from 89% of success rate in a worst-case scenario to the 100% using a complete-case analysis with satisfactory values of marginal bone resorption and good conditions of the peri-implant tissue. Ten-year follow-up using complete-case analysis shows survival rates of 100% for implants with no signs of peri-implantitis, stability of the marginal bone levels and soft tissue around the dental implants. CONCLUSIONS: The data collected show very good implant stability, absence of progressive peri-implantitis, and satisfactory aesthetical results in time (no signs of infraocclusion). CLINICAL RELEVANCE: Mini-implants can be considered a valid and stable over time solution in the restorative treatment of maxillary lateral incisors agenesis.

White spot lesions in orthodontics: prevention and treatment. A descriptive review.

White spot lesions (WSL) are demineralizations of the enamel found on the tooth surfaces. WSL are considered incipient non-cavitated caries caused by bacterial plaque activity. Subjects with malocclusion such as dental crowding and fixed orthodontic appliances have a greater number of retention sites and consequently difficulty in cleaning and greater predisposition to caries. In fact, WSL are a frequent side effect of orthodontic fixed treatments. The prevention and resolution of this problem is the goal of any orthodontist because untreated WSL can lead to the formation of deeper dental caries and restorative treatment with consequent compromise of patient satisfaction with the aesthetic result obtained at the end of the orthodontic treatment. This review is intended not only for orthodontists but also for general and pediatric dentists who want to learn how to correctly prevent, and treat this unsightly problem. On the market there are many products sold to achieve this goal, some of them can be managed independently by the patient at home, others require the intervention of the dentist. The purpose of this literature review is to understand how these substances work, to identify with which of the currently most widespread the best results have been obtained and then to provide useful information to guide the clinician in choosing the most suitable one for the patient.

Management of anterior open-bite in the deciduous, mixed and permanent dentition stage: a descriptive review.

Anterior open bite is one of the most complex malocclusions to manage. The interaction of skeletal, dental, and soft tissue effects can contribute to develop an anterior open bite. The skeletal open bite requires a more complex approach of treatment to reach function, aesthetics, and stability. The approaches vary depending on the causative factors and the age of patients. Treatment approaches for open bite patients differ when dealing with adults and growing patients. The aim of this descriptive review was to summarize the main existing treatment strategies for anterior open bite, from the noninvasive behavioural shaping to the orthodontic intrusion with skeletal anchorage.

The effectiveness of autologous demineralized tooth graft for the bone ridge preservation: a systematic review of the literature.

Resorption of alveolar ridge after tooth extraction often compromises dental implant placement and esthetic. Alveolar ridge preservation is a common procedure performed in order to preserve the pontic site for a prosthetically ideal position. This procedure has already become an indisputable need. Tooth matrix as bone substituted material poses osteoconduction and osteoinduction properties and as autologous graft, this material is free of antigenic reaction. This biomaterial allows the threedimensional reconstruction of the bone, is easy to prepare and has a low cost. The aim of this review is to summarize and put in evidence the properties of tooth as bone substitute and its use in alveolar ridge preservation. Keyword: autologous tooth, autologous graft, bone regeneration, bone substitute, alveolar ridge preservation, alveolar ridge augmentation, socket preservation.

Compliance of children with removable functional appliance with microchip integrated during covid-19 pandemic: a systematic review.

Treatments with removable appliances are widely used in Europe to correct dento-skeletal dysgnatia in the growth phase that is a period of poor cooperation of the patients. Adherence to the wear-time prescription is often not achieved and it represent the main argument against the use of removable devices. Suspected non-compliant behavior with the wear time prescription is often the subject of medico-legal disputes, which can deteriorate doctor-patient relationship. The use of microchips allows to document objectively and clarify the patient's behavior. To conduct a systematic review of the orthodontic literature to identify the factors associated with compliance in orthodontic treatment. We conduct a systematic review that aimed to identity the factors associate with compliance in orthodontic treatment. The main purpose was to assess the objective levels of time of use of the removable appliances and the self-reported levels. A literature search was conducted by the electronic databases PubMed and Cochrane Library. The following search terms were used: compliance functional removable orthodontic appliance. Randomized and nonrandomized controlled trials, prospective cohort studies, case series, qualitative and mixed-methods studies objectively assessing compliance levels were included in the study. A total of 94 articles were identified by PubMed and 14 articles by Cochrane. The papers selected were included for the qualitative analysis and categorized according to the subjects age, the clinical appliance, compliance factors, wear time and monitoring. Removable appliances are an important part of orthodontic treatment, used in growth phase of the patient. Collaboration with removable functional devices determines success / failure in treatment.

Dental trauma in the anterior sector: an analysis of the predisposing factors in a group of orthodontic patients.

AIM: The aim of this study was to analyze the predisposing factors of upper incisal trauma in children candidates for orthodontic treatment. METHODS: This is a retrospective study involving 102 consecutive patients who requested orthodontic therapy at Pediatric Dentistry Clinic of Bari University's Dental School during the time frame 2012-2019. The distribution of reported dental trauma was analyzed according to gender, type of trauma, etiology, overjet and labial competence. RESULTS: No substantial association between gender and trauma emerged from our study. Patients between the age range of 11-15 years appear to be at increased risk. A statistically significant correlation between increase in overjet and traumatic events was found. A link was discovered between labial incompetence and trauma, since this condition increases the risk of trauma by exposing part of the surface of the upper incisors. A correlation also emerged between Skeletal Class II and the increased risk of traumatic injury. CONCLUSIONS: Dental trauma, especially in the anterior sector, is a fairly frequent occurrence in pediatric and adolescent patients and is linked to several factors. In our study subjects with Skeletal Class II division I malocclusion with elevated overjet are more predisposed to dental trauma. The limitations of our study are the low number of subjects in the examined sample, and the heterogeneity of the trauma presentation.

Obstructive site localization in patients with Obstructive Sleep Apnea Syndrome: a comparison between otolaryngologic data and cephalometric values.

PURPOSE: Obstructive Sleep Apnea Syndrome (OSAS) is a respiratory disorder characterized by repeated obstructive episodes affecting upper airways.This study aims at examining the anatomical craniofacial and pharyngeal characteristics of the patient as to identify the obstructive site which triggers the pathologic process.Correlations between otolaryngologic data observed in the patient and the cephalometric ones for the identification of the obstructive site were also highlighted. MATERIALS AND METHODS: We worked on a sample of 16 patients, 12 males and 4 females, attended to at the Otolaryngology Operative Unit of Bari University Hospital.The patients underwent an otolaryngologic (ORL) diagnostic procedure which provided for ApneaGraph (AG) recording, and a dental diagnostic procedure with cephalometric assessment. RESULTS: The statistical analysis highlighted a strict correlation between the otolaryngologic value of AHI and the cephalometric values of the ANB angle, with the distance between the hyoid bone and the mandibular plane and with the distance between the hyoid bone and the plane passing between C3 and Me. CONCLUSIONS: We observed a concurrence between the ORL diagnosis of the obstruction level assessed with AG and the cephalometric values regarding respiratory tracts (IPAS and SAS). More precisely, we observed the correlation between the otolaryngologic value of AHI with cephalometric values of the ANB angle, with the distance between hyoid bone and mandibular plan, and with the distance between the hyoid bone and the plane passing between C3 and Me. Furthermore, the identification of the caudal position of the hyoid bone can be considered an alarm bell in the diagnosis of severe OSAS.

Correlation between parodontal indexes and orthodontic retainers: prospective study in a group of 16 patients.

PURPOSE: Fixed retainers are used to stabilize dental elements after orthodontic treatment. Being it a permanent treatment, it is necessary to instruct patients about a constant and continuous monitoring of their periodontal conditions and a correct oral hygiene. The aim of this study was to highlight the possible adverse effects of bonded retainers on parameters correlated to the health conditions of periodontal tissues. MATERIALS AND METHODS: We selected 16 patients, under treatment in the Orthodontics Department of University of Bari Dental School, who had undergone a lingual retainer insertion at the end of the orthodontic treatment. The patients were then divided into two groups (Control Group and Study Group) and monitored for 3 and 36 months, respectively. The following indexes were taken into consideration: gingival index (GI), plaque index (PI) and the presence of calculus (Calculus Index, CI), the probing depth and the presence of gingival recession on the six inferior frontal dental elements. RESULTS: After the observation was carried out, any of the patients showed periodontal sockets and gingival recession. In the Study Group, only 1 patient had a PI score=3, the 7 left had scores between 0.66 and 2.83. In the Control Group, one patient had score=0, the other ones showed values between 0.5 and 1.66. The mean GI in the Study Group peaked at a score of 2.83, the minimum was 0.66; whereas in the Control Group the maximum value was 2 and the minimum 0.66. The CI in the Group Study was between 1 and 2. In the Control Group it was absent in only 1 patient, whereas in the remaining 7, it had a value between 0.3 and 1. The clinical data were studied by means of the Wilcoxon test. We found a statistically significant difference for what concerns the Plaque Indexes (PI) (P>0.05) and Calculus Indexes (CI) (P>0.1) in both groups, with higher scores in the Study Group, having retainers for 36 months. Any statistically significant difference was calculated for the GI. CONCLUSIONS: We can therefore conclude that patients with lingual retainers need periodontal hygiene and treatment as to prevent, in the course of time, periodontal damages non-detectable in short-term.

Cytokine, Chemokine, and Growth Factor Profile Characterization of Undifferentiated and Osteoinduced Human Adipose-Derived Stem Cells.

Bone is the second most manipulated tissue after blood. Adipose-derived stem cells (ASCs) may become a convenient source of MSC for bone regenerative protocols. Surprisingly, little is known about the most significant biomolecules these cells produce and release after being osteoinduced. Therefore, the present study aimed at dosing 13 candidates chosen among the most representative cytokines, chemokines, and growth factors within the conditioned media of osteodifferentiated and undifferentiated ASCs. Two acknowledged osteoblastic cell models, that is, MG-63 and SaOs-2 cells, were compared. Notably, IL-6, IL-8, MCP-1, and VEGF were highly produced and detectable in ASCs. In addition, while IL-6 and IL-8 seemed to be significantly induced by the osteogenic medium, no such effect was seen for MCP-1 and VEGF. Overall SaOS-2 had a poor expression profile, which may be consistent with the more differentiated phenotype of SaOs-2 compared to ASCs and MG-63. Instead, in maintaining medium, MG-63 displayed a very rich production of IL-12, MCP-1, IP-10, and VEGF, which were significantly reduced in osteogenic conditions, with the only exception of MCP-1. The high expression of MCP-1 and VEGF, even after the osteogenic commitment, may support the usage of ASCs in bone regenerative protocols by recruiting both osteoblasts and osteoclasts of the host.

Early mandibular canine-lateral incisor transposition: case report.

PURPOSE: The main aim of the present study is to present a case of mandibular transposition between lateral incisor and canine in a paediatric patient. MATERIALS AND METHODS: A fixed multibracket orthodontic treatment was performed by means of a modified welded arch as to correct the transposition and obtaining a class I functional and symmetrical occlusion, also thanks to the early diagnosis of the eruption anomaly. RESULTS: Our case report shows that a satisfactory treatment of mandibular transpositions is obtained when detected at an early stage of the tooth development. CONCLUSIONS: The main treatment options to be taken into consideration in case of a mandibular transposition are two: correcting the transposition or aligning it leaving the dental elements in their transposed order; in both cases, the follow-ups show a stable condition, maintained without relapses. Several factors, such as age of the patient, occlusion, aesthetics, patient's collaboration, periodontal support and duration of treatment have to be considered as to prevent potential damage to dental elements and support appliances. The choice between the two treatment approaches for mandibular lateral incisor/canine transpositions mainly depends on the time the anomaly is detected.

Non-surgical periodontal management in scleroderma disease patients.

The aim of the present study is to investigate the periodontal status of people with scleroderma and their response to non-surgical treatment protocol aimed at controlling the evolution of the disease. The response to non-surgical periodontal treatment was tested on patients belonging to a scleroderma group and a control group: the data show an improvement of the periodontal conditions of all these patients in response to treatment. When compared on the same diagram, a slight remission of the periodontal disease was obtained in both scleroderma and healthy patients. This highlights the benefit to soft tissues produced by non-surgical periodontal treatment also in patients affected by systemic diseases.

Correlation between dento-skeletal characteristics and craniomandibular disorders in growing children and adolescent orthodontic patients: retrospective case-control study.

PURPOSE: The aim of this retrospective case-control study was to identify, in a group of growing children and adolescents affected by malocclusion, specific dento-skeletal characteristics which could be correlated to the onset, in the above-mentioned subjects, of craniomandibular disorders (CMD). MATERIALS AND METHODS: Among the patients treated at the Paedodontics and Orthodontics department of Bari Dental School, we recruited a group of patients with malocclusion and symptoms of temporomandibular disorders, as an experimental group. We considered as controls those patients who, match-paired to their skeletal class depending on the ANB angle, did not show any CMD sign or symptom. RESULTS: Of the 128 examined patients, 15 showed signs and/or symptoms of CMD (11.7%). When compared to 15 patients non-affected by CMD, we could not detect statistically significant differences in both skeletal and occlusal characteristics. It is still interesting to notice how in CMD patients, characteristics of skeletal hyperdivergence are often to be found. CONCLUSIONS: The present study seems to confirm that in growing children and adolescents, the presence of signs and/or symptoms of CMD is not associable to a specific vertical skeletal growth pattern or to other specific occlusal characteristics.

Oral hygiene in patients with oral cancer undergoing chemotherapy and/or radiotherapy after prosthesis rehabilitation: protocol proposal.

PURPOSE: This study was aimed at assessing the effectiveness and the importance of an oral hygiene (OH) protocol in patients undergoing radiation therapy and chemotherapy after prosthesis rehabilitation, in order to reduce or minimize oral complications. MATERIALS AND METHODS: This study was carried out at the Department of Dental Science, at the University of Bari-Italy from December 2012 to December 2015 on 34 selected patients with primary oral cancer undergoing chemotherapy and radiotherapy after prosthesis rehabilitation. They were divided into 2 groups according to their age, sex and cancer therapy. Seventeen patients were assigned to the control group and seventeen in the experimental one. In the experimental group (Table 1), patients underwent an oral hygiene protocol whereas in the control group (Table 2) patients received the usual care provided within the clinical setting. All the patients gave written informed consent. It has been asked and obtained the authorisation from the Ethics Committee of the Dental Science and Surgery Department. RESULTS: Results show that in patients undergoing the oral hygiene protocol, the complications and the risks of infection and permanent dental problems have been minimized. Indeed, of the seventeen patients undergoing the OH protocol, 70% obtained positive results and were satisfied with the program outcome. CONCLUSIONS: The role of the health care providers is essential to educate patients to adhere to the prescribed treatments and reinforce their motivation in oral hygiene. The oral hygiene procedures prevent and ameliorate oral complications due to the radiation therapy and chemotherapy.

Quality of life in fibromyalgia patients with craniomandibular disorders.

Fibromyalgia (FM) is a rheumatic disease which affects fibrous tissues and muscles; it is characterized by chronic pain and it is often associated with craniomandibular disorders (CMD). 31 patients were assessed from March 2012 to October 2012 through the administration of specific questionnaires and following neurologic and gnatologic assessment. A relevant corre-lation between FM and CMD emerges from the present study, as 80.6% of our patients report CMD symptoms with high prevalence of myofascial pain (84%). Multivariate regression analysis revealed that the patients in the present study did not differ in score of quality of life questionnaires from patients with fibromyalgia. The neuropathic pain diagnostic question-naire (DN4) scores were positively affected by belonging to group II of Research Diagnostic Criteria of Temporomandibular Disorders (RDC/ TDM) classification, suggesting the possibility of a neuropathic component in chronic pain in this CMD group, as already speculated in our study on the correlation between burning mouth syndrome and CMD and by other au-thors in studies on chronic low back pain. However, further clinic and instrumental studies are needed in order to test this as-sumption.

Prolidase deficiency: dento-facial aspects in a paediatric patient.

BACKGROUND: Prolidase Deficiency (PD) is a rare hereditary disease consisting in developmental delay, mental retardation, facial dysmorphism, splenomegaly, recurrent pulmonary infections and skin lesions. CASE REPORT: The present study reports a case of PD treated in the Paediatric Section of the Department of Dentistry and Surgery at the University of Bari. A special diagnostic and clinical approach to the patient was useful to improve his quality of life and identify some new aspects of this systemic disease. In particular, clinical features never described before are reported: low hair line, decreased osteotendinous reflexes, long upper lip, microrhinia, dentoskeletal Class III, dental age (Proffit) older than chronological age, fusion of 2nd and 3rd cervical vertebrae, incomplete atlanto-occipital fusion.

Selection of non-conventional yeasts and their use in immobilized form for the bioremediation of olive oil mill wastewaters.

The yeast population dynamics in olive wastewaters (OMW), sampled in five mills from Salento (Apulia, Southern Italy), were investigated. Three hundred yeasts were isolated in five industrial mills and identified by molecular analysis. Strains belonging to Geotrichum, Saccharomyces, Pichia, Rhodotorula and Candida were detected. Five G. candidum strains were able to grow in OMW as the sole carbon source and to reduce phenolics, chemical oxygen demand (COD) and antimicrobial compounds. One G. candidum isolate was selected for whole-cell immobilization in calcium alginate gel. The COD and phenolic reduction obtained with immobilized cells showed a 2.2- and 2-fold increase compared to the removal obtained with free cells, respectively. The immobilization system enhanced yeast oxidative activity by avoiding the presence of microbial protease in treated OMW. To our knowledge, this is the first report on G. candidum whole-cell immobilization for OMW bioremediation.

Absorption and metabolism of bioactive molecules after oral consumption of cooked edible heads of Cynara scolymus L. (cultivar Violetto di Provenza) in human subjects: a pilot study.

The current growing interest for natural antioxidants has led to a renewed scientific attention for artichoke, due not only to its nutritional value, but, overall, to its polyphenolic content, showing strong antioxidant properties. The major constituents of artichoke extracts are hydroxycinnamic acids such as chlorogenic acid, dicaffeoylquinic acids caffeic acid and ferulic acid, and flavonoids such as luteolin and apigenin glycosides. In vitro studies, using cultured rat hepatocytes, have shown its hepatoprotective functions and in vivo studies have shown the inhibition of cholesterol biosynthesis in human subjects. Several studies have shown the effect on animal models of artichoke extracts, while information on human bioavailability and metabolism of hydroxycinnamates derivatives is still lacking. Results showed a plasma maximum concentration of 6.4 (SD 1.8) ng/ml for chlorogenic acid after 1 h and its disappearance within 2 h (P< 0.05). Peak plasma concentrations of 19.5 (SD 6.9) ng/ml for total caffeic acid were reached within 1 h, while ferulic acid plasma concentrations showed a biphasic profile with 6.4 (SD1.5) ng/ml and 8.4 (SD4.6) ng/ml within 1 h and after 8 h respectively. We observed a significant increase of dihydrocaffeic acid and dihydroferulic acid total levels after 8 h (P<0.05). No circulating plasma levels of luteolin and apigenin were present. Our study confirms the bioavailability of metabolites of hydroxycinnamic acids after ingestion of cooked edible Cynara scolymus L. (cultivar Violetto di Provenza).

Effects of amitriptyline and intra-oral device appliance on clinical and laser-evoked potentials features in chronic tension-type headache.

In the present study, we examined clinical and laser-evoked potentials (LEP) features in two groups of chronic tension-type headache (CTTH) patients treated with two different approaches: intra-oral appliance of prosthesis, aiming to reduce muscular tenderness, and 10 mg daily amitriptyline. Eighteen patients suffering from CTTH (IHS, 2004) participated in the study. We performed a basal evaluation of clinical features and LEPs in all patients (T0) vs. 12 age- and sex-matched controls; successively, patients were randomly assigned to a two-month treatment by amitriptyline or intra-oral device appliance. The later LEPs, especially the P2 component, were significantly increased in amplitude in the CTTH group. Both the intra-oral prosthesis and amitriptyline significantly reduced headache frequency. Total Tenderness Score was significantly reduced in the group treated by the prosthesis. The amplitude of P2 response elicited by stimulation of pericranial zones showed a reduction after amitriptyline treatment. The results of this study may confirm that pericranial tenderness is primarily a phenomenon initiating a self-perpetuating circuit, favoured by central sensitisation at the level of the cortical nociceptive areas devoted to the attentive and emotive compounds of pain. Both the interventions at the peripheral and central levels may interrupt this reverberating circuit, improving the outcome of headache.
