Adaptações do sistema estomatognático em indivíduos com desproporções maxilo-mandibulares: revisão da literatura

This research had the aim to identify adaptations on the stomatognathic system of individuals with maxillomandibular disproportions. The literature review was carried out using national and international databases, addressing adaptations on the stomatognathic system of subjects with maxillomandibular disproportions submitted to orthognathic surgery associated to speech-language intervention. It was found that subjects with prognathism and retrognathism present adaptations in all oral-motor functions during the presurgical period. In mandibular prognathism, the most adapted function is mastication, which is characterized by vertical movements using the dorsum of the tongue for kneading the food, and less use of the masticatory muscles. In mandibular retrognathism, studies showed that deglutition is most adapted, being characterized by anterior mandibular slide, in addition to postero-anterior movement of the tongue and perioral muscles activation. After orthognathic surgery, some cases may present adequacy of the stomatognathic system functions. In other, however, adaptations may persist, making it necessary that speech-language therapists are well informed about pre-existent adaptations, in order to plan the best rehabilitation process for each case.

Ansiedade frente ao tratamento odontológico: prevalência e fatores predictores em brasileiros

Considering the negative impact anxiety can exert over dental treatment, the scope of this study was to determine the prevalence of predictors of anxiety regarding dental treatment among Brazilians. A cross-sectional study was carried out using the Corah dental anxiety scale to assess the degree of anxiety regarding dental treatment among 3000 patients. The results reveal that two out of every eight Brazilian patients manifest moderate to severe anxiety regarding dental treatment. In this sample, the degree of anxiety was higher among females (p=0.007), over 20 years of age (p=0.006), without access to the Internet and/or newspapers (p=0.016), with a low frequency of oral hygiene (p=0.001), for whom the reason for the dental appointment was curative treatment, pain or another problem rather than a check up (p=0.047) and those suffering from toothache (p<0.001). Fear and anxiety regarding dental treatment indeed exist in the Brazilian population and the findings of this study suggest that, besides the lack of economic resources, negligence with respect to oral health, gender and age may increase the degree of anxiety.

Mandibular osteomyelitis and fracture in a patient with pyknodysostosis.

Pyknodysostosis is a rare, recessive, hereditary, autosomal disease belonging to the group of bone dysplasias. Complications such as osteomyelitis and fractures of the mandible are not uncommon and appear in the most varied forms. We report a case of chronic osteomyelitis with subsequent mandible fracture, which was successfully treated with the use of a reconstruction plate and antibiotic therapy. This article outlines the clinical and radiographic characteristics of this condition based on the clinical case described and proposes an approach regarding the best form of treatment. Considering the risks of fracture subsequent to removal of the graft from long bones as well as the presence of chronic infection, difficult-to-defeat infection, and bone contact on the compression band, the best choice is a more conservative treatment.

Estudo da prevalência de fluorose dentária em Aracaju

With the aims of determining the prevalence dental fluorosis in the city of Aracaju, Sergipe State, 196 students were submitted to an oral exam, utilizing the Deans index. It was concluded that the prevalence of dental fluorosis in students ranging from 5 to 15 years old in the city of Aracaju, Sergipe State was of 8.16%, not implying in a risk to public health. However, similar studies must be done regularly, besides orientation to governmental departments responsible for water fluoridation, so that the level considered excellent for this area can be respected, avoiding such problem to occur.

Clinical study of hemodynamic changes comparing 4% articaine hydrochloride with 1:100,000 and 1:200,000 epinephrine

OBJECTIVE To evaluate hemodynamic changes with the use of 4% articaine and 2 different concentrations of epinephrine (1:100,000 and 1:200,000) in the surgical removal of symmetrically positioned lower third molars. STUDY DESIGN A prospective, randomized, double-blind clinical trial was carried out involving 42 patients each undergoing 2 surgeries on separate occasions under local anesthesia with 4% articaine and either epinephrine 1:100,000 or 1:200,000. The following parameters were assessed at 4 different moments: systolic, diastolic, and mean blood pressure; heart rate; oxygen saturation; rate pressure product (RPP); and pressure rate quotient (PRQ). RESULTS The concentration of epinephrine did not affect diastolic blood pressure or oxygen saturation during the surgeries. Significant differences between were detected for heart rate, RPP, and PRQ (P < .05). CONCLUSIONS The epinephrine concentration (1:100,000 or 1:200,000) in a 4% articaine solution influences hemodynamic parameters without perceptible clinical changes in healthy patients undergoing lower third molar removal.

Tooth embedded in tongue following firearm trauma: report of two cases

Injuries caused by projectiles from firearms involve diverse patterns of dentoalveolar trauma due to the different types of wound and extent of tissue damage. This article reports two cases in which tooth fragments were embedded in the tongue following aggression from a firearm projectile in the facial region. Radiographs confirmed the presence of foreign bodies, which were surgically removed under local anesthesia. When dentoalveolar trauma occurs in facial injuries, both hard and soft tissues must be carefully examined to avoid overlooking embedded tooth fragments not located immediately in the soft tissue.

Anestésicos Locais, Como Escolher e Previnir Complicações Sistémicas

Abstract The discovery of substances that cause a loss of sensitivity was a benchmark in the history of medicine and dentistry and is considered one of the ten most important discoveries in medicine. Such substances allow performing surgical procedures without pain, which had previously been considered an unachievable ideal in academic circles. One of the most frequent errors in dentistry is systematically employing the same local anesthetic. Dentists should choose an anesthetic solution based on the patient and procedure to be carried out. Prevention is the best treatment for systemic complications stemming from local anesthesia and is achieved through an adequate anamnesis and physical exam, which allow choosing the safest anesthetic solution for each specific case. The aim of the present study was to carry out a literature review on local anesthetics, providing readers with information to guide them in the choice and amount of anesthetic solution, thereby preventing the occurrence of systemic complications.

High weight standard and removal of third molars: a prospective randomized study

OBJECTIVE Compare the degree of exposure to adverse events during the removal of third molars between 2 groups of patients. STUDY DESIGN Researchers designed and implemented a prospective randomized study. The study consisted of overweight and normal-weight patients subjected to the surgical removal of impacted lower third molars. A wide range of predictor variables was registered in the preoperative phase. Statistical calculations were computed. RESULTS Five hundred sixty surgeries were performed involving 2 groups (1:1). Adverse events were found in 29.3% of surgeries in overweight patients. The same procedures performed on normal-weight patients resulted in a complication rate of 10.7%. Predictor variables significant to these events were detected. CONCLUSIONS Overweight patients have 3 times greater risk of experiencing morbidities during the removal of lower third molars compared with patients of normal weight. Our findings have important implications for public health, given the exorbitant growth in the population of patients with high standard weight.

Is Overweight a Risk Factor for Adverse Events during Removal of Impacted Lower Third Molars

Being overweight is recognised as a significant risk factor for several morbidities; however, the experience of the dentistry faculties focusing on this population is still low. The aim of the present study was to determine the occurrence of adverse events during removal of impacted lower third molars in overweight patients. A prospective cohort study was carried out involving overweight patients subjected to surgical removal of impacted lower third molar as part of a line of research on third molar surgery. Predictor variables indicative of the occurrence of adverse events during surgery were classified by their demographic, clinical, radiographic, and surgical aspects. Descriptive and bivariate statistics were computed. In total, 140 patients fulfilled the eligibility criteria, and 280 surgeries were performed. Patients’ mean age was years, and the proportion of women to men was 3 : 1. Eight different adverse events during surgery were recorded. These events occurred in approximately 29.3% of cases and were significantly associated with predictor variables (). Excess weight is recognised as a risk factor for the high rate of adverse events in impacted third molar surgery. The study suggests that overweight patients are highly likely to experience morbidities.
