Despite successful septoplasty surgery, some patients still complain of nasal obstruction (NO).
Our aim in the present study is to determine whether preoperative computed tomographic (CT) parameters have prognostic significance for the success of septoplasty.
Retrospective data from 61 patients in a secondary care hospital who had undergone septoplasty met the inclusion and exclusion criteria. The effects of demographic and preoperative CT parameters (internal nasal valve [INV], external nasal valve area, angle of septal deviation, choana area, aperture pyriformis area, high septal deviation [HSD], transverse diameter of midnose, anterior/posterior deviation, concha and meatus diameter [superior, middle, inferior]) were studied in relation to the change in NOSE scores and the success of surgery.
Of the 61 patients studied, 31 were male (51%) aged 18-55 years with a mean age ± SD (26.59 ± 9.41). It was found that the changes in NOSE scores were significantly different from each other (
< 0.01). Male gender, trauma history, moderate septal deviation, HSD, mucosal pathology, posterior deviation, bullous turbinate (right and left middle, right superior), and in the absence of allergy, paradoxical turbinate (right and left middle and superior), S-shaped deviation were found to have a significant correlation in the change of NOSE scores (
< 0.05). Age and internal valve differed with respect to outcome (
< 0.05). Variables in multiple linear regresion models of all parameters were found to be insignificant (
< 0.05).
Preoperative CT parameters are informative, but do not predict the postoperative success of septoplasty.

One of the most important goal of non surgical endodontic retreatment is the successful removal of gutta percha and sealers from the root canal system. A variety of techniques have been recommended for retreatment procedures for the removal of gutta-percha and sealers with or without the help of adjunctive chemical solvents, by using stainless steel hand files or nickel-titanium rotary files, gate glidden burs, heated instruments, ultrasonic instruments, and lasers 1,3. The current advancements in the design of NiTi instruments have proved efficacious in the removal of filling materials from the root canal wall and various studies have also confirmed their cleaning ability and efficacy 4,5. Nevertheless, the use of rotary instrumentation can lead to the formation of dentinal cracks in the root canal dentin. Many researchers have reported the incidence of crack formation and propagation after the procedure with manual, rotary and reciprocating instruments. The behavior of rotary instruments in the generationostar RE Endo rotary instrument proved to be most effective and least time-consuming. Hedstrom Files required more time and removed less material.
All the groups showed a similar amount of crack propagation. Less number of cracks were observed in the coronal one third and more amount of cracks were found at the apical third. Endostar RE Endo rotary instrument proved to be most effective and least time-consuming. Hedstrom Files required more time and removed less material.
One of the most specific effects of high-density dental restorative materials on head & neck cancer radiotherapy is generating variations on isodose distributions. These variations might have an impact on the accuracy and effectiveness of the radiation treatment. The aim of this study is investigating the possible dosimetric effect of six different restorative materials on isodose distributions in head & neck radiotherapy planning process.
A special phantom was developed and twenty-one caries-free human third molars (a control group + six different restorative materials) were used for the measurements. After acquiring the computed tomography (CT) images, seven treatment plans were created. Hounsfield Unit (HU) numbers, horizontal line dose profile (HLDP) and vertical line dose profiles (VLDPs) were compared with the control group.
The amalgam sample deformed the HU numbers in CT images. The median HU value for the S4 material was considerably different than the other samples. The median values wt on isodose distributions.
The findings of the present study showed that amalgam should not be used in head & neck cancer patients who are planned to have radiation therapy. A high viscosity glass ionomer cement (GIC) and a ceramic reinforced GIC sample can be used instead of amalgam to minimize the distorting effect on isodose distributions.
The aim of this study was to investigate the effects of an antioxidant on the bleaching-induced reduction in the penetration depth of infiltrant resins.
White spot lesions (WSLs) were created on 105 bovine tooth samples, each measuring 6 × 4 × 4 mm. Five samples were randomly selected for the examination of lesion characteristics. The remaining 100 samples were then divided into four groups (n = 25). In Group I, the WSLs were treated with resin infiltration (RI) only. RI was performed on Group II immediately after bleaching. In Group III, an antioxidant was applied for 2 h after bleaching, and this was immediately followed by RI. The Group IV samples were treated with RI at the end of a 1-week waiting period after bleaching. The penetration depths were evaluated through confocal laser scanning microscopy.
The lowest penetration rate, which was approximately 57%, was observed in Group II. This was followed by Group III (87%), Group IV (90%), and Group I (92%). Group II, in which the samples were infiltrated immediately after bleaching, had the lowest mean penetration percentage. All the bleached groups exhibited significantly lower penetration percentages than the nonbleached group (Group I) (
< 0.05). Antioxidant application increased the penetration significantly (
< 0.05).
Application of sodium ascorbate was found to reverse the reduced resin penetration depth and penetration percentages resulting from bleaching. The postponement of adhesive procedures after bleaching yielded similar results.

Dental professionals can play a pivotal role in educating the public about the harmful effects of smoking and encouraging them to quit the habit.
This study assesses the attitudes and practices of tobacco cessation counseling (TCC) among dental professionals in Saudi Arabia.
This questionnaire-based cross-sectional study targeted dentists and dental interns working in government and private sectors in Saudi Arabia. We conducted a descriptive analysis by using SPSS Statistics, version 25.0.
A total of 895 respondents (314 interns and 581 dentists) participated in this survey. Although the majority of respondents (93%) reported that they always ask patients about tobacco habits, only 59% reported recording tobacco habits in patients' files, and only 55% of the respondents reported explaining to patients the harmful effects of tobacco. Around 91% of the participants believe that a dental clinic is an appropriate place for TCC, and 22% believe that TCC has a negative impact on dental practice. Smoking status, work setting, and the number of years since graduation were found to be significantly associated with the respondents' attitudes and practices. Lack of training, time limitations, and lack of confidence were barriers for TCC.
Dental professionals in Saudi Arabia demonstrated relatively positive attitudes but weak practices of TCC. Continuous education and motivation are needed to improve dentists' confidence, attitudes, and willingness for TCC. Integration of tobacco control education in undergraduate curricula is recommended.

Whole-body computerized tomography (CT) scan designed as early diagnosis of traumatic injuries and prevention of unnoticeable injuries. Using Whole-body CT in trauma patients still controversial, there is no consensus on indications.
The aim of this study is to clarify indications and cut-off levels in vital parameters in trauma patients who undergo Whole-body CT to prevent unnecessary or negative scans.
We evaluated patients with trauma who applied our emergency service between 01.09.2019 and 30.09.2020. Patients above 18 years old with Whole-body CT scan included. Whole-body CT reports were evaluated according to five categories; cranial-face, vertebra, thorax, abdomen, pelvis-bone.
The review of whole-body CT reports, 46.3% detected normally. But, 53.7% of patients had injuries at least one zone, 23.3% at least two zones, and 7.4% at least three zones respectively. Prediction criteria of Whole-body CT for the patients with two or three zones injury, systolic blood pressure (SBP) ≤100 mm Hg, Glasgow coma scale (GCS) <15, and free fluid in Focused Assessment with Sonography for Trauma (FAST) were independent variables in regression analysis. When patients had at least one of three variables, the negative predictive value of whole-body CT was 96% for three zones and 91% for two zones.
The cut-off values of GCS <15 and SBP ≤100 mm Hg were useful vital parameters in making whole-body CT decisions in trauma patients in the emergency service. Also, free fluid detection in FAST can be used for whole-body CT decisions.

Sickle cell syndrome is a group of inherited hematological disorders with varying degrees of anemia, jaundice, fatiguability along with hepatomegaly and splenomegaly. The clinical presentations can be may vary and therefore require thorough investigations. We tried to evaluate the spectrum of sickle cell anemia and thalassemia in pediatric patients of our hospital.
In this cross-sectional study, A total of n = 200 consecutive cases were detected during the period of study. A thorough history and detailed clinical examination were done. Hb electrophoresis was done in the present study using HYDRASYS ® Electrophoresis Systems from Sebia.
The overall prevalence of SCD in our study was 6.83% the existence of this is found to be greater in the males as compared to females which is in agreement with prevalence across India with more male than female. Thalassemia was prevalent at the rate of 3.96%, sickle cell anemia had a prevalence of 1.98% sickle thalassemia was 0.89%. N = 20 pairs of Parents recognized genetic counseling i.e., with a single child or who wanted further children readily underwent HPLC analysis.
The existence of SCD in our study group is lesser as compared to the South India average. Preventive programs consisting of public education, population screening, genetic counseling, and prenatal diagnosis have been very effective in reducing both rates of β-Thalassemia major. Sickle cell anemia is of prime importance because of its high prevalence, morbimortality and the absence of curative treatments.
