Assessment of cephalometric characteristics in the elderly

Abstract

This cross-sectional study aimed at assessing the cephalometric characteristics in the elderly, taking into account differences between genders, age ranges, ethnic groups and dental aspects. The sample consisted of 250 elderly subjects of both genders (163 female, mean age: 68 yr.; 87 male: 70.4 yr.). Conventional lateral cephalograms for cephalometric analysis were scanned and analyzed by Dolphin Imaging software 11.5. The statistical treatment of the data evaluated the influence of gender and age range variables (independent t test), as well as ethnic group, facial profile, and dental characteristics (one-way ANOVA), on cephalometric measurements. A confidence interval of 95% and level of significance of 5% were considered for all the tests performed. The results revealed: 1) The cephalometric measurements evaluated showed significantly lower values for the female gender; 2) a significant decrease in the cephalometric values was observed in relation to the growth pattern, with the advancement of age; 3) significant cephalometric differences were observed between the ethnic groups and the facial profiles; 3) dentulous patients had greater absolute values for all the components evaluated, followed by the individuals with partial dental losses and by those who were edentulous. It may be concluded that the cephalometric alterations observed in this study are inherent to facial maturity, and that they represent specific characteristics regarding each of the variables evaluated. These modifications must be taken into account when planning the treatment for younger patients, to minimize the modifications arising from the natural aging process.

Temporomandibular Disorder Signs, Occlusal Support, and Craniofacial Structure Changes Among the Elderly Vietnamese

“…No occlusal support seems to cause loss of vertical dimension of occlusion and resulted in a shorter vertical facial height. Rosa et al [21] found that the average of the lower anterior facial height of edentulous and dentate Brazilians was 62.7 and 72.7 mm, respectively. A study conducted in Japan found that facial height does not change significantly if the elderly person has enough occluding pairs of teeth [22].…”

“…No occlusal support also reduces posterior facial height in the current study mainly because of the decreased lower facial height. Being edentulous might result in significantly shorter mandibular symphysis height, ramus height, and mandibular length, and deeper mandibular notch [9,10,21].…”

“…This longevity can be associated with improvements in the population's health conditions, together with advances in health care [1][2][3] . Aging is understood as a natural, progressive and dynamic process in which there are morphological, functional and biochemical changes that make the organism more susceptible to aggressions and deformities 4 . As a person ages, the risk of various diseases increases, including those that affect sensory and motor control of the feet.…”

“…11 Różnice płciowe są także widoczne w wybranych wartościach zmiennych twarzoczaszki. [18][19][20][21] Wymiary GDO różnicują się również w zależności od przynależność osób badanych do jednej z trzech klas szkieletowych. 22,15,16 Potwierdzają to badania, wykazujące istnienie istotnych korelacji wartości kąta ANB z powierzchnią części ustnej gardła.…”

“…11 Differences depending on gender are also observed in some selected variables of the facial skeleton. [18][19][20][21] The URT dimensions are also differentiated depending on one out of three skeletal classes that an evaluated individual belongs to. 22,15,16 This has been confirmed by studies indicating significant correlation between the ANB angle and the surface area of the oropharynx.…”
