How much does the COVID-19 pandemic affect the clinical attitudes and anxiety levels of Turkish dentists in their dental practice?

Background: To investigate whether there is a change in the attitudes and behaviors of Turkish dentists during their dental procedures against the COVID 19 pandemic. Methods: A web-based cross-sectional survey study was directed using a “Google Form” to obtain responses from dentists during February and March 2021. The survey was composed of 4 parts including: 1. demographic data (age, sex, marital status, systemic health), scope of practice (general dental practitioner versus specialist), place of practice (private versus public), and experience; 2. questions about COVID-19 management in practice and clinic biosafety routine, 3. questions about measures taken in dentistry clinics against COVID-19 and 4. questions about knowledge, attitudes and concerns of dentists towards the COVID 19 pandemic. Results: A total of 556 dentists completed questionnaire. The rate of questioning the HES code, temperature measurement and wanting each patient to rinse their mouth with anti-bacterial mouthwash before treatment were higher for specialist dentists (

İmplant planlanan bölgelerde panoramik radyografinin yeterliliğinin ve KIBT'nin gerekliliğinin farklı tıbbı eğitimi olan gözlemciler tarafından değerlendirilmesi

Amaç: Bu çalışmanın amacı, farklı eğitim geçmişleri olan klinisyenler tarafından dental implant prosedürlerinin planlanmasında panoramik radyografinin (PAN) yeterliliğinin ve konik ışınlı bilgisayarlı tomografi (KIBT) gereksiniminin değerlendirilmesidir.Gereç ve Yöntemler: 69 hastanın PAN ve KIBT' sinde; 13 hastanın maksiller anterior bölgesi, 23 hastanın maksiller posterior bölgesi, 13 hastanın mandibular anterior ve 20 hastanın mandibular posterior bölgesi dental implant yerleştirmeyi planlamak amacıyla incelendi. Görüntüler farklı eğitim geçmişleri olan araştırmacılar tarafından analiz edildi: iki pratisyen diş hekimi (DH), iki Periodontoloji uzmanı (PD) ve iki ağız, diş ve çene radyolojisi bölümü araştırma görevlisi (ADÇR). Katılımcılarla standartlaştırılmış bir ortamda standartlaştırılmış bir anket cevaplandı.Bulgular: PAN tüm bölgelerde gözlemciler tarafından yüksek oranda iyi çözünürlükte/yeterli çözünürlükte (% 62) skorlandı. Tüm bölgelerde, KIBT ihtiyacına yönelik soruda ‘kesin gerekli’ (% 49) ve ‘gerekli olabilir’ (% 26) skorları daha fazla cevaplandı. Skorların oranları bölgelere göre değişiklik gösterdi. ADÇR grubu tüm bölgelerde KIBT gerekliliğini DH ve PD gruplarından daha fazla skorladı (% 87.0, % 73.9, % 65.9, p< 0.001)Sonuç: Özellikle anterior maksilla ve anterior mandibulada, dental implant prosedürlerinin planlanmasında ek bir KIBT' nin belirgin sübjektif faydaları görüldü. KIBT eğitimi alan ADÇR bölümü araştırma görevlileri KIBT’ i daha fazla gerekli gördüler.ANAHTAR KELİMELER KIBT, implant planlama, panoramik radyografi, sübjektif değerlendirm

Ultrasonographic evaluation of mandibular elevator muscles to assess effects of attrition-type tooth wear on masticatory function

Objectives: Occlusal alterations may result in changes in the functional performance of masticatory muscles. This study was planned to evaluate mandibular elevator muscles of patients with dental attrition by using ultrasonography (USG). Methods: 30 physiologically dental attrition subjects, aged 35–65 years, were clinically examined by tooth wear index (TWI). Patient group (TWI scores of 2–4) and age-matched controls (TWI scores of 0–1) underwent ultrasonographic analysis to assess the thickness of anterior temporalis, superficial masseter muscles, bilaterally, during clench and rest positions. Results: The mean thickness of masseter and temporal muscles for rest and clench positions and the ratio between thickness of clench and rest position (C/R) were evaluated. Muscle thickness had a higher mean value in the tooth wear group. However, the only significant differences were in the C/R ratio for left side of masseter (p=0.04) and temporal muscles (p=0.03). Although, there was a negative correlation between TWI scores and the muscle C/R ratio for the tooth wear group. A significant positive correlation was found between age and TWI in both groups. Conclusion: The contraction capacity of the chewing muscles and the attrition mutually interact. This study showed an associate on between the severity of occlusal tooth wear and the C/R of chewing muscles. Although dental attrition can occur due to increased jaw muscle activation, and it can also cause a reduction in the contraction capacity of mandibular elevator muscles

Cone Beam Computed Tomographic Analysis of Paranasal Variations, Osteomeatal Complex Disease, Odontogenic Lesion and Their Effect on Maxillary Sinus

Objective:The objective of this study was to establish the prevalence of nasal septal deviation, concha bullosa, and osteomeatal complex disease (obstruction), and odontogenic lesions, along with their potential relationships with maxillary sinus mucosal thickening.Materials and Methods:(CBCT) images of 200 patients (101 males, 99 females) with 396 exposed maxillary sinuses, were inspected for presence of nasal septal deviation, concha bullosa, osteomeatal complex disease (obstruction), and odontogenic lesions related to maxillary sinus and maxillary sinus mucosal thickening.Result:One hundred nineteen patients (59%) had nasal septal deviation, 100 (50%) had at least one concha bullosa, 26 (13%) had osteomeatal complex disease on at least one side, 39 (19.5%) had odontogenic lesions related to maxillary sinuses, and 112 (56%) had evidence of mucosal thickening. There was a statistically significant relationship among osteomeatal complex disease, odontogenic lesion and maxillary sinus mucosal thickening (p=0.00). No statistically significant relationship could be established among the presence of concha bullosa, nasal septal deviation and maxillary sinus mucosal thickening (p>0.05).Conclusion:Odontogenic lesions and osteomeatal complex diseases have association with maxillary sinus mucosal thickening. CBCT imaging could be a diagnostic tool for assessment potential reasons of maxillary sinus mucosal thickening
