The aim of this study is to assess the impact of oral conditions on the quality of life (QoL) of children and adolescents with autism spectrum from the perspective of their parent-caregivers. A convenience sample, including 40 children and adolescents with autism, aged 6 to 14, attended in seven institutions for people with special health care in the state of Sergipe, Brazil. It was used the Brazilian version of the Parental-Caregivers Perceptions Questionnaire (P-CPQ) and the Family Impact Scale (FIS), which are applied to evaluate the perception of parents or caregivers on oral health-related quality of life (OHRQoL) of children and adolescents. The clinical oral examination was performed for the prevalence of dental caries and assessment of oral hygiene. The global score for the P-CPQ in the sample ranged from 0 to 63, with a mean of 13.52 (9.05). 97.5% of mothers reported that oral conditions had an impact on OHRQoL. The increase in years of schooling (p=0.016) of caregivers was associated to greater perception regarding their child’s OHRQoL. Most children and adolescents with autism had no caries experience and presented good to moderate oral hygiene. We did not find differences in OHRQoL scores according to the oral hygiene status and prevalence of dental caries. This study suggested that caregiver literacy has played a role in OHRQoL in children and adolescents with autism. Further studies with a larger sample size are needed to assess the influence of other oral health measures on QoL in this population.

This study pretends to evaluate the beneficial effects of the treatment with growth hormone (compassive off-label use) on bone regeneration and osseointegration of dental implant surgeries in elderly people. A total of 140 patients, between 35 and 82 years of age, undergoing dental surgery, receiving a total of 402 dental implants have been investigated. Informed consent was signed by all of them. From this group, 58 patients (31 males and 27 females) received a total of 209 implants and were treated with local growth hormone in the surgical bed during the procedure, and in 29 implants of this group, when surgical beds were more extensive also with daily systemic application for one month. Another 82 patients between 35 and 82 years of age (39 males and 43 female) were also submitted to implant surgery and received a total of 193 implants without growth hormone treatment. For the evaluation of results, a simple apical radiography was used. Osseointegration was determined by bone neoformation and density between and around the implant coils. Study showed that growth hormone treatment was able to induce a statistically significant decrease in the average time between the surgical approach and osseointegration of the implant. The median value for treated patients was 82 days whereas the untreated needed a median of 140 days. No differences were observed either regarding gender or groups of age. It was concluded that in all age and gender groups the reduction of the osseointegration time was very significant when growth hormone treatment was used.

Objective : To compare the Community Periodontal Index (CPI), the CPI modified and three partial-mouth periodontal protocols for estimates of prevalence, severity and extent of periodontitis in populations. Method: a convenience sample of 350 individuals (aged 35 to 74 years) from Sao Paulo underwent a full-mouth periodontal examination (FMPE) which assessed pocket depth (PD), clinical attachment level (CAL) and bleeding on probing on six sites per tooth. The CPI, CPI modified (CPIm) and three partial-mouth protocols examination (PMPE)-half-mouth 6 sites, full- and half-mouth 3 sites-were derived from the records of the FMPE and have been compared for sensitivity, absolute bias, relative bias and inflation factor in estimates of periodontitis. Results: Significant differences were found in periodontitis prevalence estimates between PMPE, in different case definitions, with relative biases ranging from -10% to -55%. The CPIm had sensitivity of 100% for gingivitis and PD ≥4 mm prevalence, and 80% for moderate and severe periodontitis in relation to FMPE, while for CPI such estimates were 70% and 50%, respectively. The full-mouth 3 sites protocol was similar to the CPIm, regarding the prevalence estimate, but CPIm overestimated severity and extent of periodontitis. The random half-mouth protocols presented low sensitivity to estimate periodontitis prevalence, although they presented small biases for severity and extension (<2.0%). Conclusion : The CPIm and the full-mouth 3 sites protocol presented satisfactory sensitivity to estimate prevalence of periodontitis in populations, being superior to the previous CPI and to the random half-mouth protocols. However, accuracy of estimates may vary with the case definition and population characteristics.

Eagle’s Syndrome is a rare condition with unknown etiology that mainly affects female patients between the third and sixth decade of life. It was first described in 1937 by Dr. Watt W. Eagle, in a study carried out in a group of patients whose main symptom was cervicopharyngeal pain caused by elongation of the styloid process and/or calcification of the stylohyoid ligament [1]. The diagnosis of this pathology is based on the anamnesis and physical examination together with imaging exams of the patients. Cervicofacial pain, palpation of the styloid process in the tonsillar fossa and limitation in neck mobility are the most classic signs and symptoms of this disease [2]. Due to the nonspecific symptoms present in these patients, this disease is usually underdiagnosed and confused with temporomandibular disorders, cervical myalgias, and even being diagnosed as atypical trigeminal neuralgias [3]. For this reason, clinical examination and imaging exams, are indispensable for the correct diagnosis and evaluation of anatomical structures [3]. We present a case of a woman with a history of eagle syndrome which was diagnosed and treated at the Hospital clinico metropolitano El Carmen Santiago, Chile.
鹰氏综合征是一种病因不明的罕见疾病，主要影响30岁至60岁之间的女性患者。1937年，Watt W. Eagle博士在一组主要症状为茎突伸长和/或茎突舌骨韧带钙化引起的颈咽部疼痛的患者中首次描述了该病[1]。这种病理的诊断是基于患者的记忆和体格检查以及影像学检查。颈面疼痛、扁桃体窝茎突触诊和颈部活动受限是本病最典型的体征和症状[2]。由于这些患者表现出非特异性症状，常被误诊为颞下颌紊乱、颈肌痛，甚至被诊断为不典型三叉神经痛[3]。因此，临床检查和影像学检查对于解剖结构的正确诊断和评价是必不可少的[3]。我们提出一个病例的妇女与鹰综合征的历史是诊断和治疗在医院临床大都市El卡门圣地亚哥，智利。

Calcium hydroxide has been widely used as intracanal medicament recently. However, removing calcium hydroxide accumulated in the apical foramen was difficult, and there is a risk of overflowing outside of the apical foramen during removing procedure. In this study, we investigated (1) the status of overflow from root apex foramen in each removal method using hand file or ultrasonic scaler, (2) possibility of reducing overflow in combination with citric acid solution or EDTA solution. Twenty-four maxillary premolar artificial teeth were performed root canal enlargement using K-fail until No.25 or No.30 size of thickness in each 12 teeth. After finishing root canal enlargement, calcium hydroxide was filled within root canal apex completely. Then calcium hydroxide was removed using ultrasonic scaler or hand file. Furthermore purified water, citric acid solution or EDTA solution was prepared as auxiliary agents respectively. After removing calcium hydroxide from each root canal was finished, the condition of calcium hydroxide overflowing from root apex was observed using stereomicroscope. Calcium hydroxide in the root canal was sufficiently removed from root canals in the groups using ultrasonic scaler. However slighted calcium hydroxide was remained around root apex in the groups using hand file. Overflow of calcium hydroxide to outside around root apex was observed both using ultrasonic scaler and hand file. The tendency of calcium hydroxide overflowing was higher in the case of using ultrasonic scaler than using hand file. In the groups of using hand file, no significant difference was observed for the different size of root canal enlargement, however overflow of calcium hydroxide was clearly higher in 30 size of root canal enlargement using ultrasonic scaler. The use of citric acid solution and EDTA solution as auxiliary agents showed that overflow of calcium hydroxide was decreased compared without using them. In particular, the decrease of overflowing was more clearly using citric acid solution than using EDTA solution. It is recommended that using hand file on removal apex areas of calcium hydroxide to reduce amount of overflowing and improve the removal efficiency. Moreover reducing the risk of calcium hydroxide overflowing are expected using citric acid solution or EDTA solution.

Objectives: The aim of the study is to evaluate the tongue force on the mandibular incisors in various malocclusions and among genders. Material and Methods: 512 subjects (340 females and 172 males) within the age group of 18-28years were selected for the study. The subjects were divided into three groups according the molar relation of the subjects. Molar relation and the tongue force exerted on the mandibular incisor of the subjects were recorded using a diagnostic kit and a Flexiforce resistive sensor respectively. Tongue force at rest (TFR), during swallowing (TFS) and maximum tongue force (MTF) were measured. Results: There was a significant increase in MTF among males than females. A significant relation among the groups when TFR and TFS were compared was also found. Conclusion: TFR and TFS were found to be influential in causing malocclusion and also a stronger tongue musculature among males than females was concluded while comparing MTF.

Background/purpose: Combination of dental titanium implants with other prosthetic metallic components may lead to metal ion release that increases the risk of adverse reactions in patients. The present study therefore aimed to determine in vitro metal ion dissolution from different alloy combinations. Materials and methods: Dental alloys were subjected to a lactic acid immersion test together with titanium implants and matched with controls. Between day 1 and 38, open direct current potentials (DCP) between the samples and the electrolyte were recorded and metal dissociation inside the electrolyte was assessed using ICP-MS. Results: Absolute DCPs of the different alloys increased significantly (p<0.001) from 100-150mV to 490-580 mV within the first two weeks of immersion, dropping to about 450mV later on largely independent of the material. Titanium showed highest dissociation rates (2.00-12.06µg/cm2 per day; p=0.0002); all other components demonstrated poor corrosive dissolution (<0.6µg/cm2 per day). After immersion of 38 days, titanium still yielded high dissociation (0.64-1.38µg/cm2 per day) for all test groups. Presence of fine gold inside the electrolyte significantly increased dissociation of titanium (p=0.027). Dissociation of iron indicated contamination from tool components used for implant production. Optical examination of non-precious metal surfaces showed no corrosive discoloration after 5 or 26 weeks of lactic acid immersion. Conclusion: Within the limitations of this study, there is no objection against the use of non-precious alloys for the fabrication of components and prostheses supported on titanium implants if gold is not present inside the same electrolyte.

The everyday practice of dentistry relies heavily on achieving adequate local anesthesia. Even though the safety record of local anesthetic agents is high, complications do occur. Palate is a favorable site for soft-tissue lesions. Various factors such as direct effects of the drug, blanching of the tissues during injection, relatively poor blood supply, and reactivation of the latent forms of herpes can all promote to tissue ischemia and a lesion in the palate. Among various complications, anesthetic necrotic ulcer is a rare and uncommon condition occurring mostly in the hard palate possibly after a local anesthetic infiltration. We report a case of palatal ulceration in a female patient after the administration of a local anesthetic to the right posterior hard palate and follow-up

Statement of the Problem: The bioceramic cements have properties that provide periradicular and root regeneration. Attributes that determine regenerative dentistry. Purpose: the objective of this study was to evaluate endodontic treatments of necrotic teeth performed with PBS HP CIMMO® cement (without gutta-percha), compared to conventional treatments, filled with gutta-percha. Materials and Method: A two-arm, double-blind, single-center, randomized, and prospective clinical trial was designed (NCT03514264). CONSORT guidelines were followed. Eighty-six patients aged 18-60 years were enrolled; only one tooth per patient was treated. Patients were treated in two sessions in Group A (gutta-percha thermoplasticization and vertical hydraulic compresssion and AH Plus® n=43) and one session in Group B (PBS HP CIMMO® n=43). The evaluation was performed one year after the treatment. Two examiners performed clinical examinations and evaluated CT images for the presence or absence of periradicular lesion. Intention-to-treat analysis was used. Results: Tomographic analyzes showed differences between the groups: group B (PBS HP CIMMO®) presented a higher number of cases with periradicular regeneration (p=0.0004). Conclusion: The results of the present study indicated the possibility of rehabilitation of necrotic teeth through endodontic filling with bioceramic (PBS HP CIMMO®), without gutta-percha, in a single session.
问题说明:生物陶瓷胶合剂具有根周和根再生的特性。决定再生牙科的属性。目的:本研究的目的是评估PBS HP CIMMO®骨水泥(不含杜仲胶)对坏死牙齿的根管治疗效果，并与填充杜仲胶的常规治疗效果进行比较。材料与方法:设计一项双臂、双盲、单中心、随机、前瞻性临床试验(NCT03514264)。遵循CONSORT指南。86名年龄在18-60岁的患者入组;每位患者只治疗了一颗牙齿。A组患者分为两个疗程(杜胶热塑性化和垂直液压压缩，AH Plus®n=43)， B组患者分为一个疗程(PBS HP CIMMO®n=43)。治疗一年后进行评估。两名检查人员进行临床检查并评估CT图像是否存在神经根周围病变。使用意向治疗分析。结果:层析分析显示各组之间的差异:B组(PBS HP CIMMO®)的根周再生病例较多(p=0.0004)。结论:本研究结果表明，不含杜仲胶的生物陶瓷(PBS HP CIMMO®)根管充填可以一次性修复坏死牙。

The article`s purpose was to understand the sociodemographic and epidemiological profile of the homeless population of Canoas, a metropolitan region of Porto Alegre, in Brazil. To accomplish this homeless population census from Canoas, the information contained in the records of all users registered at Consultóriona Rua (Street Clinic) was used from the beginning of activities in December 2014 until July 2016. Totalizing that, 347 people were collected in the months of June, July and August 2016.84.4% are men, 55.9% self-described as white. Most 64.1% have incomplete primary education, with recycling as the main occupation in 20.6 % of cases. 36.1% reported being on the street due to the use of some psychoactive substance, being 62.0% alcohol users. 69.1% make daily consumption of psychoactive substance, 23.6% have some STIs, considering 14.6% carriers of the HIV virus. Get to know their specificities and needs according to the location in which they are inserted, will make it possible to create means, through public policies, to recover their sense of belonging, and provide their rights guaranteed by law, treating them with dignity.
