It can be concluded, therefore, that no relationship exists between cervical posture in the sagittal plane and TMD.

Objective  The aim was to correlate radiomorphometric indices and biochemical analyses as an auxiliary method in bone evaluation in male and female patients with chronic kidney disease–mineral and bone disorder (CKD-MBD) and controls. Materials and Methods  Nine radiomorphometric indices and four biochemical parameters were obtained: mental index (MI), height at the mental foramen, total mandibular height (THM), panoramic mandibular index (PMI), original height of the mandible, alveolar bone resorption, distance from the mental foramen to the alveolar bone crest (MF-ABC), mandibular cortical index (MCI), trabecular bone pattern, parathyroid hormone (PTH), calcium (Ca), phosphorus (P), and Ca × P product (Ca × P). Statistical Analysis  The Mann–Whitney U -test, chi-squared test, and Spearman’s correlation were applied at a significance level of 95%. Results  There was a moderate negative and significant correlation between MI, PMI, and PTH in female patients with CKD-MBD as well as between THM, MF-ABC, and Ca × P. The MCI and trabecular bone pattern indicated altered bone quality in male patients. Conclusions  The radiomorphometric evaluation was an auxiliary, noninvasive method to detect possible alterations in the cortex and mandibular bone trabeculation in male and female patients with CKD-MBD.

Objectives To investigate the presence of soft tissue calcifications in the head and neck region on panoramic radiographs of older adults. Methods We analysed 1176 panoramic radiographs obtained between January 2013 and December 2018 from individuals of both sexes aged 60 years or older, who were referred by dental specialities to the Dental Imaginology Service of the Federal University of Rio Grande do Norte, Brazil. The types of soft tissue calcification evaluated were as follows: carotid artery calcification (CAC), thyroid cartilage calcifications, triticeous cartilage calcifications, sialoliths, tonsilloliths and lymph node calcifications. The presence of soft tissue calcifications was correlated with age and sex. The chi‐square test with continuity correction was used for the calculation of p values and the evaluation of the proposed associations. Prevalence ratios and 95% confidence intervals were also calculated. Results At least one type of soft tissue calcification was found in 43% of the sample. The main calcifications detected were CAC, thyroid and triticeous cartilage calcifications, tonsilloliths, sialoliths, calcified lymph nodes, and phleboliths. Mean patient age was 67.47 years and there was a predominance of females (62.8%) in the sample. Bivariate analysis showed a statistically significant association between female sex and the presence of thyroid and triticeous cartilage calcifications and between male sex and the presence of tonsilloliths. Conclusion Routine panoramic radiography permits the identification of soft tissue calcifications that may be indicators of future cardiovascular disorders, the referral to a medical service and the establishment of therapies for stroke prevention.

r e s u m o informação sobre o artigo Historial do artigo: Recebido a 12 de fevereiro de 2019 Aceite a 23 de maio de 2019 On-line a 30 de maio de 2019 Objetivo: Avaliar a ocorrência de achados radiográficos em radiografias panorâmicas de idosos. Métodos: Estudo observacional transversal, no qual 1006 radiografias panorâmicas digitais foram analisadas. As radiografias pertenciam a indivíduos com 60 anos ou mais, de ambos os sexos, do banco de dados do Departamento de Odontologia da Universidade Federal do Rio Grande do Norte. Os achados radiográficos observados foram associados ao sexo, idade e número de dentes (Qui-quadrado, p<0,05). Resultados: 66,2% da amostra era do sexo feminino e 33,8% do sexo masculino. A idade variou de 60 a 97 anos (média de 67,76 anos). A maioria (68,3%) foi composta por desdentados parciais, seguidos por desdentados totais (31,1%) e apenas 0,6% dentados. Os achados mais prevalentes foram reabsorção de rebordo alveolar (94,2%), cálculo dentário (42,9%), cárie (29,8%), lesão periapical (23,6%) e raiz residual (23,6%). Os indivíduos do sexo masculino apresentaram maior ocorrência de cárie (p=0,002), cálculo (p<0,001), lesão periapical (p<0,001), raiz residual (p<0,001) e reabsorção óssea horizontal/vertical (p=0,006). Os pacientes acima de 75 anos tiveram mais cárie radicular (p=0,03) e cálculo dentário (p=0,021). Os desdentados totais tiveram menor incidência de dente incluso/semi-incluso (p=0,012) e raiz residual (p<0,001) em comparação com os desdentados parciais e dentados, e maior incidência de expansão do seio maxilar (p<0,001). Conclusões: Evidenciou-se uma alta ocorrência de achados radiográficos na amostra, o que comprova a grande necessidade de assistência odontológica pela população idosa. (Rev Port
