Anatomical relationship between maxillary posterior teeth and the maxillary sinus in an Indonesian population: a CT scan study.

BACKGROUND: The anatomical proximity between the root apex of the maxillary posterior teeth and the maxillary sinus can lead to complications, including odontogenic maxillary sinusitis. While several studies have investigated similar variables in different populations, there is limited research on the Indonesian population. This study aimed to describe the anatomical position of the maxillary posterior teeth in relation to the floor of the maxillary sinus using CT scans. METHODS: A total of 122 patients (432 maxillary premolars and 1,282 maxillary molars) underwent CT scans to evaluate 1,711 roots. The vertical relationship between the root apex of the maxillary posterior teeth and the maxillary sinus was classified into three types: IS (inside sinus), CO (sinus contact), and OS (outside sinus). RESULTS: The IS type was predominantly found in the palatal roots of the first molars, accounting for 20% of the total roots in this type. The CO type was most frequently observed in the mesiobuccal roots of the second molars, representing 18% of the total roots in this type. The OS type was most commonly found in the first premolar, comprising 20% of the total roots in this type. CONCLUSIONS: The palatal roots of the first molars exhibited the highest frequency of proximity to the maxillary sinus. CT scans can effectively assess the relationship between the root apex of the posterior teeth and the maxillary sinus. CLINICAL RELEVANCE: Clinicians should consider this information comprehensively when planning treatments for maxillary molars.

Nasolabial anthropometry using 3D computed tomography scan reconstruction: baseline study for nasolabial correction in Indonesian children with cleft lip and palate / Antropometría nasolabial mediante reconstrucción con tomografía computarizada 3D: estudio de referencia para la corrección nasolabial en niños Indonesios con fisura labiopalatina

Background: The normal nasolabial structure of infants and chil-dren from East Asian, specifically Indonesian, descent groups has been less explored in the literature. This anthropometric study is used as a guide in lip repair in patients with clefts. This retrospective study used archived CT images from the Indonesian population. Materials and Methods: Computed tomography records of children under 5 years of age were extracted from a provincial hospital. The images were then filtered based on the inclusion and exclusion criteria and then the 2D slices were reconstructed using the open source software Invesalius. Twenty-five variable nasolabial parameters of the nasolabial structure were then measured in the 3D rendering mode. Images with craniofacial dysmorphism or cannulas that passed over the nasolabial structure were excluded. Results were summarized using descriptive statistics. Results: Fourteen of 128 CT images were included in this study. The samples were divided into two age groups: 0-12 months and 25-54 months. There were moderate to strong, positive correlations between age and all nasolabial variables, which were statistically significant (p<0.05) except for nasal length, nares circumference, columella width, superior philtrum width, philtrum column height, and cutaneous upper lip height. Conclusions: This study described anthropometric measurements of normal nasolabial structures as a reference point for lip correction surgery. However, to obtain more accurate anthropometric guidelines, further studies with larger sample sizes are desirable. Although surgical repair of the lip is usually performed within the first year of life, some cases of surgery are performed after infancy.

Antecedentes: La estructura nasolabial normal de bebés y niños de grupos de ascendencia de Asia oriental, específicamente de Indonesia, ha sido menos explorada en la literatura. Este estudio antropométrico se utiliza como guía en la reparación del labio en pacientes con fisuras. Este estudio retrospectivo utilizó imágenes de tomografía computarizada archivadas de la población indonesia. Materiales y Métodos: Se extrajeron los registros de tomografía computarizada de niños menores de 5 años de un hospital provincial. Luego, las imágenes se filtraron según los criterios de inclusión y exclusión y luego se reconstruyeron los cortes 2D utilizando el software de código abierto Invesalius. Luego se midieron veinticinco parámetros nasolabiales variables de la estructura nasolabial en el modo renderizado 3D. Se excluyeron imágenes con dismórfica craneofacial y cánula que pasa sobre la estructura nasolabial. Los resultados se resumen mediante estadística descriptiva. Resultado: En este estudio se incluyeron catorce de 128 imágenes de TC. Las muestras se dividieron en dos grupos de edad: 0-12 meses y 25-54 meses. Hubo una correlación positiva de moderada a fuerte entre la edad y todas las variables nasolabiales, que fueron estadísticamente significativas (p<0,05) excepto la longitud nasal, la circunferencia de las narinas, el ancho de la columela, el ancho del filtrum superior, la altura de la columna del filtrum y la altura cutánea del labio superior. Conclusión: Este estudio describió las medidas antropométricas de estructuras nasolabiales normales como base para la cirugía de corrección de labios. Sin embargo, para obtener directrices antropométricas más precisas, son deseables más estudios con tamaños de muestra más grandes. Aunque la reparación quirúrgica del labio normalmente se realiza dentro del primer año de vida, en algunos casos la cirugía se realiza después de la infancia.

Volumetric growth analysis of maxillary sinus using computed tomography scan segmentation: a pilot study of Indonesian population.

The aim of this study is to investigate the volumetric measurements of the maxillary sinus among Indonesian population through computed tomography (CT) scan semi-automated segmentation. This project collected 802 retrospective head CT scan archives from Department of Radiology, Hasan Sadikin Hospital, Bandung, Indonesia between 2019-2020. Patients with craniofacial anomalies/pathology fracture in proximity of the maxillary sinuses, and mediocre image quality were excluded from this study resulting only 97 CT scan archives (194 maxillary sinuses; 52 males; 45 females; age range 0-25 years old). Three-dimensional craniofacial structures were reconstructed and volumetric measurements of the maxillary sinus were computed through semi-automated segmentation using ITK-SNAP. This study recorded the initial phase of maxillary sinus pneumatization during infancy. The maxillary sinus developed until reaching the maximum of average maxillary sinus volume at 13,278.73 mm3 in 16 to 20 years old group in which afterwards fell to 12,325.21 mm3. There was no difference found between right and left maxillary sinus volume. This study revealed that the pneumatization of maxillary sinus begin during infancy and climb until reaching the second decade of life, in which after that slowly decrease. Moreover, no difference between right and left maxillary sinus volume was detected. The volumetric dimension of maxillary sinus presented in this study may serve as the basis knowledge surgical intervention of maxillary sinus and its related structures.

Correlation between Taste Threshold Sensitivity and MMP-9, Salivary Secretion, Blood Pressure, and Blood Glucose Levels in Smoking and Nonsmoking Women.

Cigarette smoking can cause taste receptors to increase the taste threshold value. Consequently, the consumption of sugar and salt will not be controlled, therefore causing systemic diseases such as hypertension and diabetes. Nicotine and tobacco in cigarettes can stimulate MMP-9 which plays vital physiological roles in normal tissue growth and repair processes. This study aimed to find the correlation between taste threshold sensitivity and MMP-9, salivary secretion, blood pressure, and blood glucose levels in smoking and nonsmoking women. This was a cross-sectional study consisting of young adult women aged 18-24 years. Subjects were divided into two groups: the nonsmoking and smoking groups. In the combined data of both groups, the sweet taste threshold was correlated with age (r = 0.308, p=0.008), blood glucose levels (r = 0.238, p=0.043), and MMP-9 (r = -0.297, p=0.011). The salt taste threshold was only correlated with systolic blood pressure in the smoking (r = 0.440, p=0.032) and combined data groups (r = 0.260, p=0.026). By using partial correlation, it was shown that the relationship between the salt taste threshold and systolic blood pressure was influenced by smoking habits. The sweet taste threshold in women was found to correlate with age, blood glucose levels, and MMP-9 levels. On the other hand, there was a significant relationship between the salt taste threshold in women with systolic blood pressure, which was the only correlation analyzed in sthis study that was found to be influenced by smoking. However, both sweet and salt taste thresholds were not statistically correlated with salivary secretion.

Preliminary Research: Description of Lip Print Patterns in Children and Their Parents among Deutero-Malay Population in Indonesia.

INTRODUCTION: Human identification is vital not only in legal medicine but also in criminal inquiries and identification. Cheiloscopy is the study of lip prints which are unique, individual, and heritable that is used for personal identification purposes in forensic odontology. OBJECTIVE: The aim of this study is to identify the possibility of the child to inherit the lip print patterns from their parents and also to describe the lip print patterns in children and their parents among the Deutero-Malay population. METHOD: The descriptive research used lip samples of 90 individuals including father, mother, and a child who are biologically related and their age ranges from 12 to 60 years old. The samples chosen are from the Deutero-Malay ethnic in Indonesia at least for the past two generation who obeys all the exclusion criteria of this research. Purposive nonrandom sampling method was used to collect samples by photography technique using a digital camera, and the data obtained were then analysed using Adobe Photoshop CS3 software. Grooves and wrinkles of primary quadrants one, three, six, and seven of lips were studied according to Suzuki and Tsuchihashi's classification in 1971. RESULT: In the present study, it is found that Type I' (30.28%) is the most dominant lip print pattern and Type I (1.39%) is the least dominant among the Deutero-Malay population. Besides, this study has shown that the similarity of lip print pattern between mother and the child (57.89%) is greater compared to the father and the child (42.22%). CONCLUSION: Based on this, we can conclude that lip print can be inherited and dissimilar for every population of race; likewise, the Deutero-Malay population has the Type I' as the most dominant lip print pattern.
