title: Comparison between a piezoelectric device and rotary instruments in implant site preparation: an in vivo morphological, histological analysis using pigs

description: OBJECTIVE: To carry out a histological comparison, at different postoperative periods, of bone tissue repair after implant site preparations on the tibia of pigs using both a piezoelectric device and rotary instruments. METHODS: Surgical procedures were performed on the tibia of four pigs. Five perforations were made in the left tibia using star shaped piezosurgery tips (Piezosonic Driller(r)) and five perforations in the right tibia using carbon coated rotary drills (DSP Biomedical(r)). The pigs were then sacrificed at 2, 7, 14, and 28 days. The tibiae were removed and the tissues were prepared for histological processing and analysis under a light microscope. RESULTS: The histological analyses showed similar results at 2 days and both groups presented inflammatory infiltrate. At 7 days, the drill system produces a regular surface preparation and the process of bone repair was greater when compared with the piezoelectric device. At 14 days the presence of new bone formation was more intense with the drill system. However, at 28 days both systems showed similar results, with the presence of an organized, newly formed bone tissue. CONCLUSION: It was possible to conclude that both implant site preparations, using the piezoelectric device and rotatory instruments, resulted in similar bone neoformation at 28 days.

title: Sialolithiasis of minor salivary glands

description: Sialolithiasis, or salivary calculus, is a disease of the salivary glands, characterized by the formation of mineralized structures within the excretory salivary ducts or the glandular parenchyma. Approximately 80% occur in the submandibular gland, followed by the parotid and sublingual glands. Although rare, sialolithiasis can also occur in the minor salivary glands. Although the oral cavity and upper lip are the most common sites, they can develop in any region of the oral cavity that contains minor salivary glands. Treatment is based on surgical excision of the lesion, with a favorable prognosis. This study presents three cases of sialolithiasis of minor salivary glands of the upper and lower lip, addresses their clinical characteristics and correlation with microscopic findings, diagnosis and treatment plans. Etiology and factors that should be considered during diagnosis, appropriate treatment and improved prognosis are discussed in this study.

title: Weight loss promoted by the Intra-oral Alimentary Satiety Device in a morbidly obese patient

description: OBJECTIVE: To evaluate the weight loss fostered by the Intra-oral Alimentary Satiety Device in a patient diagnosed as morbidly obese. METHODS: A female patient diagnosed as morbidly obese who was seeing a nutritionist was examined. Based on her medical history and anthropometric assessment, a hypocaloric diet was prescribed. The nutritional state was assessed by the Body Mass Index (BMI). The patient was advised to wear the Intra-oral Alimentary Satiety Device, and an assessment by a dentist was suggested to discard contraindications. The appliance was then manufactured with dental molding material, orthodontic stainless steel wire, and heat-cured dental acrylic resin. The patient wore the device at every meal, putting it on 5 minutes in advance. For the data analysis the SPSS Statistics 17.0 software was used. RESULTS: In her first consultation, the patient weighed 115 kg and was 1.62 m tall, with BMI = 43.82 Kg/m. Weight loss was 13.3 kg, representing 11.57% of the initial weight. In relation to the BMI, the total loss was 5.06 Kg/m, representing 11.55%. CONCLUSION: The Intra-oral Alimentary Satiety Device can be considered a safe and effective method which, together with a hypocaloric diet, shows satisfactory results, thus proving to be an important auxiliary option in the treatment of obesity.

title: Endodontic treatment of a mandibular hypertaurodontic second molar

description: Taurodontism is the consequence of a developmental disorder in which the invagination of Hertwig's epithelial root sheath doesn't occur at a proper level. As a result, the pulp body and the chamber of a multi-root tooth, usually permanent molar teeth, are enlarged by the apical displacement of the pulp floor. Despite its clinically normal appearance, the morphological variation of this tooth can be diagnosed by a routine radiographic exam that shows enlarged apico-occlusal pulp chamber and short roots. Due to these anatomical variations, endodontic treatment of a taurodontic element is a clinical challenge given the complexity of localization and instrumentation of the root canal system. According to the degree of displacement of the pulp floor, taurodontism can be classified as: hypotaurodontism, mesotaurodontism and hypertaurodontism. This study objective is to report a clinical case of a patient who was submitted to endodontic treatment of the second inferior molar affected by hypertaurodontism.

title: Auxiliary chemical therapies in the treatment of aggressive periodontitis: current aspects

description: Aggressive periodontitis, a distinct clinical entity of periodontal disease, is characterized by a pronounced episodic and rapid destruction of periodontal tissues and may result in rapid and early loss of teeth. Some studies have shown that conventional mechanical debridement together with oral hygiene is often not sufficient to disease control. Recent studies of this condition have shown beneficial effects of auxiliary therapies or adjuncts such as the administration of systemic and locally antimicrobials. Among the local adjuncts, the literature presents antiseptics, antibiotics and photodynamic therapy. Antibiotics and anti-inflammatory represent systemic adjuncts. Regardless of the results presented by each of them, the difficulty of establishing a single protocol for all cases is recognized depending on the individual response shown by each patient. The aim of the present study was to review the current results about chemical adjuncts administration associated with conventional treatment in cases of aggressive periodontitis and suggest clinical protocols.

title: Perimolysis: case report

description: Perimolysis is a form of dental erosion, characterized by dental tissue demineralization without bacterial involvement. It can be of intrinsic or extrinsic origin. Extrinsic origin is considered when it is caused by excessive consumption of acid drinks and foods such as soft drinks, alcoholic beverages, acid fruit and prescription drugs for daily use. When caused by gastrointestinal disorders, such as those resulting from bulimia, anorexia nervosa and gastroesophageal reflux, it is considered of intrinsic origin. The acid action can cause erosion on palatal/lingual incisor surfaces, and occlusal and palatal/lingual posterior tooth surfaces causing pain (dental hyperesthesia). Treatment is often multidisciplinary, and the causes should be identified, eliminated or controlled. In dentistry, the approach must include preventive measures to reduce future risks, and restorative intervention using materials such as glass ionomer cement, resin composite, or endodontic and prosthetic rehabilitation in more complex cases. The aim of this study was to describe the restorative treatment in the case of a patient with this condition.

title: ANALYSIS OF CONE PENETROMETER LIQUID LIMIT FLOW CURVE USING MATHEMATICAL MODEL

description: This paper presents a mathematical model which defines the moisture-penetration relationship using British cone. The developed mathematical model gives a unique opportunity of computing or predicting the cone penetration of the soil even at a very low moisture content at which, due to practical limitation it is impossible to determine the soil penetration. The model was found to fit the moisture-penetration data reasonably well. The model was used to compute the penetration of soil at the plastic limit of 394 soils. This study indicates that the plastic limit cannot be defined using one unique penetration value.

title: Dens invaginatus: case report

description: Dens invaginatus is one of the most frequent malformations in dental elements. It can affect all teeth, even primary and supernumerary ones. It consists of an invagination of the crown surface, which happens during odontogenesis and penetrates the interior of the pulp chamber of the dental elements involved. In some cases, it can reach the apical tooth area. The maxillary lateral incisor is the most common site of occurrence. Due to its complex and variable anatomy, the tooth may present pulp necrosis and open apex, making it difficult to salvage. Oehlers classified them into types I, II, and III according to their complexity. This article reviews the literature and describes the treatment of a maxillary central incisor with type II invagination. The invaginated structure in this case detached due to various instrumentations during the change of dressing phase, facilitating root canal filling. In conclusion, this case shows that many methods are capable of removing the invaginated area of a dens invaginatus type II.
