Location of posterior superior alveolar artery and evaluation of maxillary sinus anatomy with computerized tomography: a clinical study

Objectives: Knowledge and evaluation of the maxillary sinus anatomy before sinus augmentation are essential for avoiding surgical complications. Posterior superior alveolar artery (PSAA) is the branch of maxillary artery that supplies lateral sinus wall and overlying membrane. The aims of this study were to examine the prevalence, diameter, and location of the PSAA and its relationship to the alveolar ridge and to study the prevalence of the sinus pathology and septum using computerized tomography (CT) scans. Materials and methods: One hundred and twenty‐one CT scans (242 sinuses) from patients undergoing sinus augmentation procedure and/or implant therapy were included. Lower border of the artery to the alveolar crest, bone height below the sinus floor to the ridge crest, distance of the artery to the medial sinus wall, diameter of the artery, and position of the artery were measured; presence of septa and pathology were recorded from CT sections. Results: Prevalence of sinus septa and sinus pathology was 16.1% and 24.8%, respectively. Artery was seen in 64.5% of all sinuses and was mostly intraosseous (68.2%). Mean diameter of PSAA was found 1.3 ± 0.5 mm. No significant correlation between the diameter of the artery and age was observed. Conclusions: The results from this study suggested that CT scan is a valuable tool in evaluating presence of sinus pathology, septa, and arteries before maxillary sinus surgery. Although variations exist in every patient, the findings from this study suggest limiting the superior border of the lateral window up to 18 mm from the ridge to avoid any potential vascular damage.

The ımpact of handicap severity on oral and periodontal status of patients with mental retardation

Aim: Mental retardation (MR) subjects comprise a considerable amount of the community and are susceptible to oral and periodontal problems due to insufficient oral care. The aim of this cross-sectional study was to determine the oral health and periodontal status of MR patients in Turkey with regard to periodontal indices and Decay missed filling teeth (DMFT) scores and compare findings according to severity of the MR. Materials and methods: One hundred and five MR patients were included to the study and divided into 3 groups according to MR severity diagnoses. Demographic variables like age, gender, disabled sibling, BMI, living an institution and clinical parameters like plaque index (PI), gingival index (GI), bleeding on probing (BOP), probing depth (PD), clinical attachment level (CAL), missing teeth and DMFT scores were recorded from all subjects. Appropriate statistical analyses were used to compare the findings. Results: There were no statistically significant differences between groups according to age, gender, disabled sibling, living status and DMFT scores. Clinical periodontal indices and the number of missing teeth were showed a statistically significant increasing trend with the severity of MR (p < 0.05). Correlation analysis showed significant positive correlations between PI and periodontal disease measures like GI, PD, CAL and BOP and also between PI and DMFT (p < 0.05). Conclusion: The deteriorated teeth condition and deprived periodontal health of MR patients may be most likely caused by the poor oral hygiene and may be worsen with the severity of the MR

Three-Dimensional Calculation of Sinus Augmentation Volume after Maxillary Sinus Floor Elevation

Abstract Objectives: This study aimed to calculate the volume of the maxillary sinus and grafted part of it with different modes of three-dimensional reconstruction software. Materials and Methods: This retrospective volumetric cone-beam computed tomography study was carried out on 21 patients/ 36 maxillary sinuses who had undergone maxillary sinus lift surgery using a lateral approach, between 2010 and 2016 at the Department Periodontology. All statistical analyses were performed by using the NCSS (Number Cruncher Statistical System, Kaysville, Utah, U.S.A.) software. P values 0.05). An occupied portion of the sinus cavity after lateral sinus floor elevation surgery was approximately 14.87 %. Furthermore, the volume through manual and automatical modes of the software do not affect the results (p>0.05). The right and left sides of the maxillary sinus volumes were not different from each other. Gender and measuring mode was not found to be related to volumetric values of the maxillary sinus cavity. Conclusions: The grafted volume of the sinus cavity was defined as a safe volume in terms of serious complications during and after the surgery

Is there a gender difference in anatomic features of incisive canal and maxillary environmental bone?

Objectives The effect of gender on anatomic structures and various body systems were illustrated in the literature. The purpose of this study was to identify the influence of gender and tooth loss on incisive canal characteristics and buccal bone dimensions in the anterior maxilla. Materials and methods Computed tomographies ( CTs ) of 417 male and 516 female patients in four dental clinics were included in this study. The diameter and the length of the incisive canal; width and the length of the bone anterior to the canal; palatal bone length, root length, and root width of the central incisor teeth were measured and recorded from CT sections. Results Mean incisive canal length was 11.96 ± 2.73 mm and 10.39 ± 2.47 mm in men and women, respectively, ( P  < 0.05). In men, mean canal diameter was 2.79 ± 0.94 mm whereas in women it was 2.43 ± 0.85 mm and this difference was statistically significant ( P  < 0.05). Men had significant higher buccal bone dimensions (length and width of the bone anterior to the canal) than women. Absence of teeth in the anterior maxilla decreased incisive canal length and buccal bone dimensions; however, canal diameter remain unchanged. Conclusions Present results suggested a gender related differences in anatomic features of incisive canal and surrounding buccal bone. In addition, crestal canal diameter, buccal bone length, and thickness parameters might be different in distinct countries.Peer Reviewedhttp://deepblue.lib.umich.edu/bitstream/2027.42/99051/1/clr2493.pd

Do gender and torus mandibularis affect mandibular cortical index? A cross-sectional study

<p>Abstract</p> <p>Background</p> <p>The interactions between torus and several factors such as age, gender, and dental status have not been studied comprehensively. The purpose of this study was to determine the effect of gender on the mandibular cortical index (MCI) and to investigate a possible association between torus mandibularis (TM) and MCI.</p> <p>Methods</p> <p>The study consisted of 189 consecutive patients referred to Department of Oral Diagnosis and Radiology of Hacettepe University within 30 workdays. Patients who did not have systemic disorders affecting bone density were included; and the age, gender, dental status and existing TM of the patients were recorded. Morphology of the mandibular inferior cortex was determined according to Klemitti's classification on panoramic radiographs.</p> <p>Results</p> <p>MCI was affected by age and gender (<it>P </it>< 0.05). No significant relationship was found between TM and MCI (<it>P </it>> 0.05).</p> <p>Conclusion</p> <p>In the study population, MCI was affected by age and gender. As age increased, semilunar defects could be seen on the cortex of the mandible and MCI values increased. Women appeared to have higher MCI values than men.</p
