          Abstract

          Un tema central en la arqueología de Mendoza ha sido la intensificación agrícola y sus implicancias socioculturales sobre la salud de las poblaciones humanas. A pesar de los estudios bioarqueológicos realizados, son escasos los análisis sobre lesiones periapicales (LP) dentales que involucran aspectos teóricos y metodológicos recientes. El objetivo de este trabajo es analizar la prevalencia de las diferentes LP en individuos del Holoceno Tardío del Centro-Norte de Mendoza, y su posible relación con la transición dietaría. La muestra incluyó 26 cráneos de adultos correspondientes a poblaciones previas (Bloque Temporal I; ca. antes de 1000 años AP; n=20) y posteriores a la intensificación agrícola (Bloque Temporal II; ca. después de 1000 años AP; n=6). Se estimó la presencia y ubicación alveolar de LP (granulomas, quistes y abscesos crónicos). El 46,2% (12/26) del total de los individuos presentaron algún tipo de LP, donde un 92% (11/12) pertenece al Bloque Temporal I. En estos 12 inviduos se identificaron 30 LP, de las cuales los granulomas fueron más frecuentes (63,3%) que los quistes (36,7%). Los alveolos del maxilar fueron los más afectados (5,6%), principalmente en los molares (85,7%). Se observó una disminución significativa de las LP en individuos de periodos donde se produjo la intensificación agrícola. Por lo tanto, las LP parecen asociarse a una economía cazadora-recolectora, posiblemente relacionada a la exposición de la pulpa por desgaste dental grave.

          Agriculture has been a central issue in Mendoza´s archaeology, due to its socio-cultural implications and its effects on population health. However, there are few studies on dental periapical lesions (PL) that involve recent theoretical and methodological aspects. The aim of the paper is to analyze the prevalence of the different PL in individuals of the Late Holocene of the Center-North of Mendoza, and its possible relation with the dietary transition. The sample included 26 skulls of adults corresponds to populations before and after agricultural intensification, Temporary Block I (before 1000 years BP, n = 20) and Temporary Block II (after 1000 years BP, n = 6), respectively. The presence and alveolar location of PL (granulomas, cysts and chronic abscesses) were estimated. Periapical lesions were identified in the 46.2% (12/26) of the sample, where 92% (11/12) belongs to the Temporary Block I. In these 12 individuals 30 PL were identified, of which the granulomas were more frequent (63.3%) than the cysts (36.7%). The alveoli of the maxilla were more affected (5.6%), with higher prevalence in molars (85.7%). There was a significant decrease in PL in individuals from periods where agricultural intensification occurred was observed. Therefore, PL seems to be associated with a hunter-gatherer economy, possibly related to the exposure of the pulp due to severe dental wear.

          Prevalence of apical periodontitis and frequency of root-filled teeth in an adult Spanish population.

          To estimate the prevalence of teeth with apical periodontitis (AP) and root-filled teeth in an adult Spanish population. A total of 180 subjects, aged 37.1 +/- 15.7 years, presenting as new patients to the Faculty of Dentistry, Seville, Spain, were examined. All participants underwent a full-mouth radiographic survey (14 periapical radiographs). The frequency of root canal treatment and the periapical status of all teeth, using the periapical index (PAI) score, were assessed. An intraobserver agreement test on PAI scores produced a Cohen's kappa of 0.77 (substantial agreement). Results were analysed statistically using the Chi-square test. Apical periodontitis in one or several teeth was found in 110 subjects (61.1% prevalence), and 73 (40.6% prevalence) had at least one root-filled tooth. Among subjects with root-filled teeth, 48 (65.8%) had AP affecting at least one root-filled tooth. A total of 4453 teeth were examined, of these 186 (4.2%) had AP. The total number of root-filled teeth was 93 (2.1%), of which 60 (64.5%) had AP. Among non-root filled teeth, only 2.9% had AP. The prevalence of AP in connection with molar teeth was higher (5.5%) than for premolar (4.5%) and anterior teeth (3.2%; P < 0.01). More premolar and molar teeth were root-filled (2.8 and 2.7%, respectively) than anterior teeth (1.3%; P < 0.01). The prevalence of AP increased with age. The prevalence of AP in root-filled and untreated teeth, and the frequency of root-filled teeth were comparable to those reported in previous similar studies carried out in European countries. The prevalence of root-filled teeth with AP was found to be higher compared to that demonstrated in other epidemiological studies.

              Differentiation of periapical granulomas and cysts by using dental MRI: a pilot study

              The purpose of this pilot study was to evaluate whether periapical granulomas can be differentiated from periapical cysts in vivo by using dental magnetic resonance imaging (MRI). Prior to apicoectomy, 11 patients with radiographically confirmed periapical lesions underwent dental MRI, including fat-saturated T2-weighted (T2wFS) images, non-contrast-enhanced T1-weighted images with and without fat saturation (T1w/T1wFS), and contrast-enhanced fat-saturated T1-weighted (T1wFS+C) images. Two independent observers performed structured image analysis of MRI datasets twice. A total of 15 diagnostic MRI criteria were evaluated, and histopathological results (6 granulomas and 5 cysts) were compared with MRI characteristics. Statistical analysis was performed using intraclass correlation coefficient (ICC), Cohen’s kappa (κ), Mann–Whitney U-test and Fisher’s exact test. Lesion identification and consecutive structured image analysis was possible on T2wFS and T1wFS+C MRI images. A high reproducibility was shown for MRI measurements of the maximum lesion diameter (intraobserver ICC = 0.996/0.998; interobserver ICC = 0.997), for the “peripheral rim” thickness (intraobserver ICC = 0.988/0.984; interobserver ICC = 0.970), and for all non-quantitative MRI criteria (intraobserver-κ = 0.990/0.995; interobserver-κ = 0.988). In accordance with histopathological results, six MRI criteria allowed for a clear differentiation between cysts and granulomas: (1) outer margin of lesion, (2) texture of “peripheral rim” in T1wFS+C, (3) texture of “lesion center” in T2wFS, (4) surrounding tissue involvement in T2wFS, (5) surrounding tissue involvement in T1wFS+C and (6) maximum “peripheral rim” thickness (all: P < 0.05). In conclusion, this pilot study indicates that radiation-free dental MRI enables a reliable differentiation between periapical cysts and granulomas in vivo. Thus, MRI may substantially improve treatment strategies and help to avoid unnecessary surgery in apical periodontitis.
