Mandibular asymmetry was not independently associated with sex, age, or absence of posterior teeth. The only verified independent association was between mandibular asymmetry and sagittal jaw relationship.

Background:Osteoradionecrosis of the jaw (ORNJ) is the most severe and complex sequel of head and neck radiotherapy (RT) because of the bone involved, it may cause pain, paresthesia, foul odor, fistulae with suppuration, need for extra oral communication and pathological fracture. We treated twenty lesions of ORNJ using low-level laser therapy (LLLT) and antimicrobial photodynamic therapy (aPDT). The objective of this study was to stimulate the affected area to homeostasis and to promote the healing of the oral mucosa.Methods:We performed aPDT on the exposed bone, while LLLT was performed around the bone exposure (red spectrum) and on the affected jaw (infrared spectrum). Monitoring and clinical intervention occurred weekly or biweekly for 2 years.Results:100% of the sample presented clinical improvement, and 80% presented complete covering of the bone exposure by intact oral mucosa.Conclusion:LLLT and aPDT showed positive results as an adjuvant therapy to treat ORNJ.

Com o aumento da expectativa de vida da população, torna-se importante garantir aos idosos maior longevidade com qualidade de vida. Este estudo objetivou estimar a contribuição das condições sociodemográficas na percepção de qualidade de vida em idosos participantes dos grupos de convivência. Foram realizadas entrevistas com 141 idosos, sobre questões relacionadas a variáveis sociodemográficas e autoavaliação da qualidade de vida. O χ ² foi utilizado para testar associações. Para o domínio físico, as variáveis foram inseridas em um modelo de regressão logística múltipla não condicional. Resultados: 73% dos idosos responderam estar satisfeitos com sua qualidade de vida e 69,5% avaliaram sua saúde como boa. No domínio ambiental, a renda familiar e a escolaridade mostraram-se associadas. No domínio físico, a renda familiar, a escolaridade, a condição de estar sozinho e a idade de 80 anos ou mais mostraram-se associadas. A maioria da população investigada classificou sua qualidade de vida como boa, mas a idade avançada mostrou-se estatisticamente associada à pior percepção de qualidade de vida no domínio físico.

The aim of this study was to evaluate the mesiobuccal root of maxillary first molars, according to the root canal configuration, prevalence and location of isthmuses at 3 and 6 mm from the apex, comparing cone-beam computed tomography (CBCT) analysis and cross sectioning of roots by thirds. Images of the mesiobuccal root of 100 maxillary first molars were acquired by CBCT and then roots were cross-sectioned into two parts, starting at 3 mm from the apex. Data were recorded and analyzed according to Weine's classification for root canal configuration, and Hsu and Kim's classification for isthmuses. In the analysis of CBCT images, 8 root canals were classified as type I, 57 as type II, 35 as type III. In the cross-sectioning technique, 19 root canals were classified as type I, 60 as type II, 20 as type III and 1 as type IV. The classification of isthmuses was predominantly type I in both CBCT and cross-sectioning evaluations for sections at 3 mm from the apex, while for sections at 6 mm from the apex, the classification of isthmuses was predominantly types V and II in CBCT and cross-sectioning evaluations, respectively. The cross-sectioning technique showed better results in detection of the internal morphology of root canals than CBCT scanning.

Objectives The aim of the present study was to investigate whether peri-implant clinical parameters (modified plaque index (mPI), bleeding and/or suppuration on probing (B/SOP)) and local factors (type of prostheses, screw emergence, platform diameter, and abutment angulation) might contribute to the development of additional bone loss and peri-implantitis around dental implants. Materials and methods Two hundred seventy-seven external hex connection implants placed in the posterior maxilla of 124 patients were retrospectively evaluated. They were divided into two groups: physiologic bone loss < 2 mm (PBL) or additional bone loss ≥ 2 mm (ABL). GEE logistic regression was applied to evaluate the influence of type of prostheses (implant-supported single crown (ISSC), fixed partial denture (ISFPD), and full denture (ISFD)) and clinical parameters (mPI and S/BOP) on bone loss. Results Among the 277 implants, 159 (57.4%) presented PBL and 118 (42.6%) presented ABL. Within the ABL group, 20.6% implants were diagnosed with peri-implantitis. mPI significantly correlated with the type of prosthesis and the highest value of mPI (index = 3) was observed in ISFD (23.8%). Moreover, peri-implantitis was more frequently associated with ISFD (32.79%) than ISSC and ISFDP (13.79% and 13.48, respectively) Conclusions ISFD in the posterior maxilla presented high rates of ABL and showed a higher prevalence of peri-implantitis. None of the local factors seemed to contribute to the development of these conditions. Further investigations are needed to prospectively support the results of the present study. Clinical relevance Patients rehabilitated with ISFD should be carefully monitored and have more frequent maintenance visits to prevent or control peri-implant bone loss.

Objectives: To measure dental anxiety in children, determine its association with behavior exhibited during treatment and evaluate the use of informative and aversive behavior management techniques. Material and Methods: A cross-sectional study was carried out with 51 children aged 6-12 years submitted to restorative dental procedures at the pediatric dental clinic of the Franciscano University Center (Brazil) between May and December 2013. Anxiety was measured using the Venham Picture Test and behavior during treatment was analyzed using the Frankl Behavior Scale. Variables were submitted to descriptive statistics. The chi-square test was used to determine associations between anxiety and categorical variables, considering associations with pvalue p ≤ 0.05 to be statistically significant. Results: Twelve children (23.5%) exhibited anxiety prior to dental procedure. Anxiety was not significantly associated with age (p=0.669), gender (p=0.478), behavior during treatment (p=0.915) or behavioral management techniques (p=0.701). Moreover, no significant association was found between changes in the level of anxiety after procedure and the behavior management techniques used during treatment (p=0.828). Conclusion: A high percentage of children exhibited dental anxiety. However, anxiety prior to dental procedure was not associated with any of the variables analyzed and no association was found between changes in the level of anxiety after procedure and the informative or aversive behavior management techniques used during treatment.

Introduction: Facial skeletal asymmetry is commonly found in humans and its main characteristic is menton deviation. The literature suggests that occlusal and masticatory problems arising from tooth absence could be related to the development of such asymmetries. Objective: The aim of this cross-sectional study was to estimate the prevalence of mandibular skeletal asymmetries and to investigate its association with posterior tooth absences. Methods: Tomographic images of 952 individuals aged from 18 to 75 years old were used. Asymmetry was the analyzed outcome, and it was categorized into three groups according to gnathion displacement in relation to the midsagittal plane (relative symmetry, moderate asymmetry, and severe asymmetry). Patients were sorted by the presence of all posterior teeth, unilateral posterior tooth absence, or bilateral posterior tooth absence. Chi-square test with a significance level of 5% was used to verify the association between posterior tooth absence and asymmetry. Results: Results show relative symmetry present in 55.3% of the sample, as well as the prevalence of 27.3% for moderate mandibular asymmetry and 17.4% for severe asymmetry. Moderate and severe mandibular asymmetries occurred in a higher proportion in patients with unilateral posterior tooth absence. However, there was no statistically significant difference between the analyzed groups (p = 0.691). Conclusions: In this study, mandibular asymmetries did not present any association with the absence of teeth on the posterior area of the arch.
