To compare the effects of bimaxillary surgery ( Maxillary advancement and mandibular setback) and mandibular setback surgery (Bilateral Sagittal Split Osteotomy) on the pharyngeal airway space (PAS) and the hyoid bone position in a skeletal class III patients.

Thirty four subjects (21 males, 13 females, mean age 26.5 ± 8 years) with skeletal class III pattern (ANB angle of -2° to -6°) were divided into two groups of equal sizes. Group A consisted of 17 individuals who underwent Bilateral Sagittal Split Osteotomy (BSSO)and Group B consisted of 17 individuals who underwent bimaxillary surgery. In both the group, lateral cephalograms were taken, traced and analyzed for the specified parameters at 3 intervals, pre treatment (C1), post surgical (C2), and post orthodontic treatment (C3). Changes in PAS was evaluated at 3 levels i.e, nasopharynx (Upper PAS), oropharynx (Middle PAS) and hypopharynx (Lower PAS). Changes in hyoid bone position were evaluated in anteroposterior and vertical direction at all the 3 int Osteotomy, Pharyngeal airway space.

Patients undergoing bimaxillary surgery showed a significant increase in the airway at the level of nasopharynx. Hyoid bone returned to its original position by the end of orthodontic treatment in the bimaxillary surgery group. This study suggested that while treating a skeletal class III malocclusion it is advised to perform maxillary advancements along with mandibular setback surgery. Key wordsBimaxillary surgery, Hyoid bone, Bilateral Sagittal Split Osteotomy, Pharyngeal airway space.

The current treatment for head and neck cancer involves radiotherapy, systemic therapy and surgery in a multidisciplinary approach. Unfortunately, cancer therapies can lead to local and systemic complications or side effects such as mucositis, which is the most common dose-dependent complication in the oral cavity and gastrointestinal tract. Mucositis can cause a considerably reduced quality of life in cancer patients already suffering from physical and psychological exhaustion. Moreover, radiotherapy interruptions due to toxicity can impact negatively in local control and survival. The main purpose of this study was to analyze patient satisfaction of Ectoin solution use in radiotherapy or radiochemotherapy-induced oral mucositis.

This is an institutional prospective analysis including 15 patients, conducted by two Spanish centers, between October 2019 and May 2020. Patients were treated with Ectoin solution during Radiotherapy and one month after the end of the treatment, three times per day. A seven-ítem Likert scale was used. We present our descriptive statistic regarding doctors and patients´s satisfaction.

Our results suggest that Ectoin solution relieves mucositis and is well tolerated by patients.

We observed a favorable repercussion in the oral mucositis management and suggest a potential benefit of treating it.

Head, neck, and especially oral cavity are common and specific sites for lesions. Those oral lesions contain a high viral load of KSHV virus and are one of the signs of disease severity. The development of KS in HIV-infected patients is classically described in case of low CD4 count, but recently reported cases revealed oral KS despite a robust CD4 count, such observations being possibly linked to interactions between periodontal germs and the oncogenic KSHV virus. We present two cases of KS location on the oral mucosa in HIV patients with gingival inflammation despite efficient antiretroviral treatment and immune restoration. Those cases suggest that the diagnosis of oral KS lesions should be considered by oral surgeons, dermatologists, and infectious specialists, when managing any suspicious lesion in an HIV patient, even with undetectable HIV viral loads, or in a seronegative patient with unprotected sexual activity.

To determine whether there is a correlation of bruxism (sleep, daytime, or both) with oral health-related quality of life and facial pain of muscular origin in dentate individuals.

Seventy-four dentate patients (complete dentition) were included in this study. These individuals had pain in the facial muscles due to temporomandibular disorder (TMD). Smokers; and those with obstructive sleep apnea, TMD of joint origin associated or not with pain, malocclusion, and cancer; and users of illicit drugs, psychiatric medications, and alcohol were excluded. Obstructive sleep apnea, bruxism (of sleep and/or daytime), facial muscle pain, and oral health-related quality of life were assessed by the following questionnaires Berlin Questionnaire, Pintado

. questionnaire, VAS (Visual Analog Scale) facial muscle pain questionnaire, and Oral Health Impact Profile - 14. Four groups were created 1) no bruxism; 2) sleep bruxism; 3) daytime bruxism; and 4) sleep and daytime bruxism. Spearman's correlation test was applied to verify if there was a correlation between the collected data.

values less than 0.05 were considered statistically significant.

There was a positive correlation of daytime bruxism with mean pain in the last 3 months (

<0.05) and the worst pain experienced in the last 3 months (

In view of the importance of pulp sensibility tests in clinical decision-making and the impact of psychological factors on test results, we evaluated in this study dental pulp responses to pulp sensibility tests (ie, cold and electric) in patients with anxiety and depression.

A number of 90 people age 20 to 30 participated in the study, including 30 healthy and 60 with anxiety and depression, whose disorder was approved by a psychiatrist based on the Symptom Checklist 90-R questionnaire. Pulp sensibility tests included electric and cold ones were performed on lateral mandibular teeth. The cold test results were recorded based on the visual analogue scale (VAS) pain scoring (0 no response, 10 worst pain). Electric pulp test was performed using a digital pulp tester. AZD1480 clinical trial The lowest current that stimulated a pulp response was recorded. The data were analyzed using the Mann-Whitney and Kruskal-Wallis tests.

The cold test pain intensity was significantly higher in patients than in healthy subjects and was significantly associated with the severity of anxiety and depression. In addition, the electric pulp test current to evoke a response was significantly lower in patients than in healthy subjects and was also significantly associated with the severity of anxiety and depression.

Given the limitations of this study, anxiety and depression significantly affect the results of pulp sensibility tests.

To evaluate the stability of the transverse correction with a hybrid maxillary expansion appliance in the bone and tegumental piriformis opening in relation to bone age and maturation of the midpalatal suture (MPS).

15 patients with a mean initial age of 14.9 years (SD=1.50), 7 (46.7%) were female and 8 (53.3%) were male, treated with a hybrid maxillary expander. Cone beam computed tomographic (CBCT) images were collected in three phases T1 (orthodontic records), T2 (21.33 days (SD=10.68) after the end of expansion screw activation) and T3 after 9.13 months (DP=2.41) after the expansion screw was activated. In CBCT, measurements were performed in the nasal cavity considering the tegumental piriform opening (sagittal-axial sections) and bone (sagittal-axial-coronal sections) and the stage of MPS maturation (sagittal-axial sections). Repeated measures ANOVA was used for continuous variables and Friedman's ANOVA for the ordinal variable followed by Bonferroni's tests for

Tllary expansion appliance was effective in opening the midpalatal suture of all patients in the present study, without influence of the initial stage of MPS maturation and bone age. There was a relapse of the increase in the bone and tegumental piriform openings. Key wordsMaxillary expansion, orthodontic anchorage procedures, nose.

Patients often compliant sensitivity to high-intensity light irradiated application during dental procedures. This study aims to investigate tooth sensitivity caused by high-intensity light irradiated from an intraoral scanner (IOS) and a light-curing unit (LCU).

Forty-five teeth from 45 healthy volunteers were included. These were equally classified into three groups using the cold test (4 ± 1 °C) and NRS pain assessment; A=control, B=cavity without sensitivity, and C=cavity with sensitivity. Two thermocouple probes were attached to the cervical area of the experimental and control tooth with a composite resin. Tooth sensitivity response by participant grip force was monitored. The digital oscilloscope was used to record two surface temperatures and a pain response during an IOS or a LCU irradiation. The high-intensity light from a LCU and an IOS was randomly applied at 2 mm above the cervical area for 20s. The data were compared statistical with two-way repeated measures ANOVA and Pearson's correlation.itivity response. Key wordsLight curing unit, intraoral scanner, tooth temperature, dentine sensitivity.

Primary hyperparathyroidism (pHPT) is the third most common endocrinopathy, affecting 1-3% of postmenopausal women, with a total incidence of 21.6 cases per 100,000 people in the adult population. This study aimed to analyze the oral health and related aspects of individuals with pHPT.

A cross-sectional observational study was carried out on 51 patients diagnosed with pHPT associated with multiple endocrine neoplasia type 1 (MEN-1) (G1) or sporadic pHPT (G2). The oral aspects investigated were periodontal parameters, salivary flow, presence of dental caries, number of restored or missing teeth, and presence of tori. The biochemical parameters were collected in periods close to the dental evaluation.

In G1, 29 individuals (19 females) aged 40.24±13.06 years were included; in G2, 22 individuals (21 females) aged 64.09±10.01 years were included. Grade 2 mobility (
