Abstract Introduction The maxillary sinus and its variations are very important to dentistry and rhinology. Objective To investigate the effect of the accessory maxillary ostium (AMO) on the variations of adjacent structures of the maxillary sinus. Methods The computed tomography (CT) images of 400 patients were retrospectively evaluated. The prevalence of AMO was calculated. The relationship between morphological variations of adjacent structures of maxillary sinus such as agger nasi cell (ANC), Haller cell (HC), nasal septum deviation (NSD), hypertrophy of inferior concha (HIC), pneumatization of middle concha (PMC), mucus retention cyst (MRC), mucosal thickening (MT), and maxillary sinusitis (MS), as well as the presence of AMO, were investigated. Results Presence of AMO was diagnosed in 42 patients (10.5%), having been found in 4.5% of the patients only on the right side, in 1.25% of the patients only on the left side, and in 4.75% of the patients on both sides. There is an increasing incidence of ANC, HC, NSD, HIC, and PMC in the presence of AMO and MS. There is a decreasing incidence of MRC in the presence of AMO. Furthermore, AMO does not affect the incidence of MT. Conclusion This study showed that most parameters, except for MRC and MT, had increasing incidence in the presence of AMO. It is important for radiologists and rhinologists to have knowledge about the location of AMO and the presence of variations of MS adjacent structures to avoid surgical complications.

Abstract Objective: The aim of this retrospective study is to investigate the prevalence of Infraorbital Canal Protrusion (ICP) degree into the maxillary sinus and its relationship with variations in adjacent structures on Cone Beam Computed Tomography (CBCT) images. Methods: 350 CBCT images (700 Infraorbital Canal [IC]) were evaluated retrospectively. ICP was divided into 3 subtypes according to the protrusion degree. The correlation between IC types and variations in adjacent anatomical structures (Haller cell, middle nasal concha pneumatization, maxillary sinus mucosal thickening and septa) was evaluated. The distance between Infraorbital Canal and Cnine Root (IC-CR) was also measured. For type 3, measurements were performed on IC as the length of the bony septum from the IC to the Mxillary Sinus Wall (IC-MSW), the distance from the inferior orbital rim, where the IC begins to protrude into the maxillary sinus (IOR-ICP), the vertical distance from the IC to the Maxillary Sinus Roof (IC-MSR) and Floor (IC-MSF). Results: The prevalence of type 1, 2 and 3 was 62.9%, 29.1%, and 8% respectively. IC-CR was 10.2, 10.7 and 11.4 mm in type 1, 2 and 3, respectively. IC-MSW, IOR-ICP, IC-MSRand floor IC-MSF was 3.8, 10.9, 7.4 and 27.7mm, respectively. On the right and left side, statistically significant correlation was found between IC types and the presence of the Haller cell and sinus septa. But there was no significant correlation between IC types and middle concha pneumatization. Conclusion: Accurate diagnosis of ICP is very important in preventing infraorbital nerve damage in surgical procedures to be performed in the maxillary region. The results of this study could be a guide for surgical planning in this region. Level of evidence: Retrospective study.

RESUMEN: La salud oral y dental son partes vitales de la salud general del bebé, y las visitas dentales tempranas brindan una importante intervención centrada en la prevención y asesoramiento a los padres sobre la salud bucal. Por lo tanto, evaluar la edad y las principales quejas de los niños es importante durante su primera visita al dentista (FDV por sus siglas en inglés). El propósito de este estudio fue determinar la edad, motivo de visita, respuesta conductual y estado de caries en la FDV y evaluar los factores que afectan estos parámetros. A los padres de 325 pacientes pediátricos (159 hombres; 166 mujeres; edad media 7,20±2,78 años) en su FDV se les pidió que llenaran un cuestionario solicitando información sociodemográfica y el historial médico de su hijo, hábitos de cepillado y motivos de presentación a la consulta dental. También se registraron las puntuaciones de dientes cariados-faltantes-obturados (dmft/DMFT). Las respuestas conductuales del niño durante la FDV se evaluaron de acuerdo con la escala de calificación de conducta de Frankl (FBRS). Un mayor nivel de educación materna y una puntuación de dmft/DMFT se asociaron con una edad más temprana de la FDV. La causa más común de la FDV fue la caries dental en el 33,5% de los pacientes, seguida del dolor de muelas (29,5%). La mayoría de los niños mostró un comportamiento positivo (46,7%), con un comportamiento positivo afectado por la edad y un comportamiento negativo afectado por el puntaje dmft/DMFT y la distancia del hogar. La puntuación media de dmft/DMFT fue de 8,1±4,4 y se vio afectada negativamente por la frecuencia de cepillado de dientes y los ingresos familiares. Los resultados de este estudio indican que los niños turcos que viven en Edirne se presentan a una edad avanzada para la FDV. Es importante concienciar a los padres sobre el cuidado de la salud dental para garantizar que los niños asistan a su FDV a una edad temprana.

ABSTRACT: Oral and dental health are vital parts of general baby health, and early dental visits provide significant prevention-focused intervention and parental counseling regarding oral health. Evaluating the age and main complaints of children is therefore important during their first dental visit (FDV). The purposes of this study were to determine the age, reason for the visit, behavioral response, and caries status at the FDV and to evaluate the factors affecting these parameters. Parents of 325 pediatric patients (159 males; 166 females; mean age 7.20±2.78 years) at their FDV were asked to fill out a questionnaire requesting sociodemographic information and their child’s medical history, brushing habits, and reasons for attending dental consultation. The decayed-missing-filled-teeth (dmft/DMFT) scores were also recorded. The child’s behavioral responses during the FDV were evaluated according to Frankl’s Behavior Rating Scale (FBRS). Higher maternal education level and dmft/DMFT score were associated with earlier FDV age. The most common reason for the FDV was dental caries in 33.5% of patients, followed by toothache (29.5%). Most of the children showed positive behavior (46.7%), with positive behavior affected by age and negative behavior affected by the dmft/DMFT score and distance from home. The mean dmft/ DMFT score was 8.1±4.4 and was negatively affected by toothbrushing frequency and family income. These study results indicate that Turkish children living in Edirne present at a late age for the FDV. Raising awareness in terms of dental health care among parents is important to ensure that children attend their FDV at an early age.

Abstract Objective: To identify the citation features and review articles on odontomas using bibliometric analysis. Material and Methods: A list of studies about odontoma was obtained by searching using the Scopus database. Abstracts or full texts were read and evaluated. After then, 50 most cited articles were achieved. Studies were categorized as citation numbers, citation density, journal name, article type, the affiliation of the first author and publication year. Descriptive statistics were used to analyze the results. Results: The most frequently cited article received 358 citations, while the least frequently cited article received 42 with a mean of 94.3 citations per article. The mean citation density was 5.13. The study with the highest citation density (12.31) was published in 2006. The highest citation number was found in the 2000s following the 1990s. The 50 most cited articles were published from 1971 to 2011, with 84% (42 of 50) published after 1990. USA (n = 9) and Brazil (n = 6) were the two most contributing countries. According to article type, there were eight (16%) review articles. Conclusion: The USA found to have a strong influence on research about odontoma, followed by Brazil. All researches were reported in English, and most of them were published in good quality journals.
