“…The results of the present study in relation to the degree of ossification of the suture in the 10-year age groups showed that ossification increased with aging; however, some cases of completely open sutures were observed in the >20-year age groups. The results of the present study are consistent with those of previous studies (10, 11, 18, 25). Nguyen (2008) carried out a study on 20 patients over 70 years of age and reported that the midpalatal suture is the only suture that might not close completely even in the elderly (11).…”

“…In the present study, the effect of gender on the degree of ossification of the suture was not significant; thus, only a significant increase in ossification in females was observed one decade later compared with males, which is contrary to the results reported by Chracanovic and de Fátina Batista, who believed that closure of the suture and skeletal maturation in females occurred earlier than that in males (3, 28). However, in the study by Nguyen (2007), no relationship was found between gender and the closure of the midpalatal suture, which is consistent with the results of the present study (25). In a study by Angelieri et al (2012) on CBCT images of 140 patients with an age range of 5.6–58.4 years, subjects over 11 year of age exhibited all the developmental stages mentioned above for the midpalatal suture.…”

“…In addition, in a study by Poorsattar et al, some cases of incomplete ossification of the suture were observed at ages >40 years (10). In another study with the use of CBCT images, in only 13% of the adult subjects completely closed sutures were detected (25). In addition, the results of 30 micro-CT analyses in a study by Krobmacher et al in 28 patients 14 to 17 years of age showed no significant relationship between closure of the suture and age (18).…”

Background and ObjectiveThe degree of ossification of the midpalatal suture is an important factor in the selection of treatment procedure, especially in young individuals. Considering the discrepancies in the results of studies on the exact time of the closure of this suture, the present study was undertaken to evaluate ossification and morphology of the suture with the use of CBCT.MethodsIn the present cross-sectional study, the CBCT images of the maxilla in 144 Iranian subjects (72 males, 72 females) with an age range of 10 to 70 years, referring to a private radiology center in Sari, Iran, were evaluated. The CBCT images were evaluated in the axial cross-sectional slice at 1 mm intervals to determine morphology and the maturation stage of the suture and its degree of ossification. The six developmental stages that were observed were as follows: stage A, a direct line without disturbances; stage B, a scalloped appearance in the suture; stage C, two parallel lines with a scalloped appearance that were connected at some points; stage CD, the anterior portion was similar to stage C, and the posterior region was similar to stage D; stage D, ossification only in the palatine bone; stage E, complete ossification of the suture. The degree of ossification of the suture was calculated with the use of the ratio of the length of the ossified segment to the entire length of the suture. Data were analyzed with Spearman’s correlation test, Chi-squared test, t-test, ANOVA, Mann-Whitney U, and Kruskal-Wallis test. Intra-observer agreement was calculated with the use of weighted kappa coefficient. Data were analyzed with SPSS 17.ResultsThere was a strong correlation between the age groups and the developmental stages of the midpalatal suture in both genders (r=0.681, p<0.001). The ossification process occurred in the posterior to anterior direction in 98% of the cases. There was a significant relationship between aging and the degree of ossification (p<0.001); however, the difference was not significant between the two genders (p=0.193).ConclusionAlthough the rate of suture closure increased with aging, age was not a reliable factor alone to determine the developmental stage of the suture. Use of CBCT is necessary in all the patients to determine the degree of ossification and morphology of the midpalatal suture.

ObjectiveThe purpose of this study was to determine whether predicting maturation of the midpalatal suture is possible by classifying its morphology on cone-beam computed tomography (CBCT) images and to investigate relationships with other developmental age indices.MethodsThe morphology of the midpalatal suture was assessed by using CBCT images of 99 patients. Axial plane images of the midpalatal suture were classified into five stages according to the classification scheme. To make the assessment more accurate, the morphology and fusion of the midpalatal suture were additionally investigated on coronal cross-sectional planar images and volume-rendered images. Bone age was evaluated using the hand and wrist method (HWM) and cervical vertebrae method (CVM); dental age (Hellman's index), sex, and chronological age were also assessed. To evaluate relationships among variables, Spearman's rho rank test was performed along with crosstabs using contingency coefficients.ResultsThe HWM and CVM showed strong correlations with the maturation stage of the midpalatal suture, while other indices showed relatively weak correlations (p < 0.01). Through crosstabs, the HWM and CVM showed high association values with CBCT stage; the HWM demonstrated slightly higher values (p < 0.0001). Based on the HWM, the midpalatal suture was not fused until stage 6 in both sexes.ConclusionsAmong developmental age indices, the HWM and CVM showed strong correlations and high associations, suggesting that they can be useful in assessing maturation of the midpalatal suture.

“…This method experiences problems with both accuracy and precision of the determined age at death. By observing ectocranial sutures during autopsy activities, the authors focus their attention on the morphology of the sutures and their level of obliteration [1][2][3][4][5][6][7][8]. From a sample of 100 individuals, the inaccuracy and imprecision of the Meindl and Lovejoy method was evident.…”

A Preliminary Study of the Relationship between Obliteration of Cranial Sutures and Age at Time of Death

During a forensic investigation, the determination of age at death is typically based on the level of skeletal development. Cranial sutures may help a forensic investigator to determine age at death since there is a predictable interval of age linked to their obliteration. The progression of the obliteration is divided in four stages (from 0 to 3), with the last stage indicating complete obliteration, and specific locations on the sutures are considered most useful for the estimation of age at death. However as more of the sutures are obliterated, the traditionally reported interval of age at death grows wider, with a complete obliteration of the sutures referred to a range of 34 to 76 years. Thus one would expect that the cranial sutures of an older person should be completely obliterated. When completely closed, which should happen over the age of 80 years, the sutures nearly disappear and at the last level of obliteration they are no longer visible, in this preliminary study, the authors analyzed a sample of 100 skull photographs taken during post mortem examinations. This study is focused on a macroscopic study of sagittal and coronal sutures. In some cases, the complete obliteration of cranial sutures was visible for individuals with age ranging from 60 to 70 years old. In particular the authors observed the presence of sutures that were not completely obliterated in subjects aged more than 70 years. The aims of this study were to draw attention to these features; to avoid misinterpretation about the age of skeletal remains; and to offer evidence that these criteria may not be reliable for forensic investigation, at least until further study and recalibration to known data.
