The current overview of the devices of temporary anchorage placed on the palatal bone: CBCT study.

Temporary anchorage devices (TADs) are frequently applied to different anatomic areas with different protocols to increase skeletal effects and anchorage in orthodontic treatment planning. It has been reported in many literatures that primary stability for orthodontic TADs is significant for long-term survival rate. For this reason, different areas of the palatal region, which has many indications, have been widely used in the studies. In this evaluation where bone quality and thickness are important, density, bone thickness, and fractal dimension (FD) on cone beam computed tomography (CBCT) will provide more predictable clinical results. The aim of this study was to evaluate bone thickness, density, and FD in the palatal region of the first, and second premolars, and first molars. There was a remarkable difference (p < 0.05) between the parameters of FD, thickness and density of bone in the identified areas in the palatal region. In terms of thickness and FD, the 1st premolar region had significantly higher values than the other regions (p < 0.05). In terms of density, the values in the right 1st molar and right 1st premolar regions were significantly higher (p < 0.05). The 1st premolar region is an ideal site for placement of palatal TADs. CBCT-assisted preliminary evaluation of FD value, bone density, and thickness may increase clinical success when selecting the location of TADs to be applied to the palatal bone.

Effects of thyme on halitosis in gingivitis patients: Can thyme mouthwash prevent halitosis-A randomized trial.

OBJECTIVES: Bad breath is a condition that negatively affects people's social interactions and quality of life. The aim of this study was to evaluate the effect of thyme mouthwash on intraoral halitosis, gingival index (GI) and plaque index (PI) in patients with gingivitis. METHODS: In this retrospective study, 60 gingivitis patients (30 women/30 men) received initial periodontal treatment followed by oral hygiene instructions (OHI) and then were divided into four groups: The control group (C) received only OHI, while chlorhexidine (CHX) mouthwash was prescribed to the CHX group, Zinc acetate and CHX diacetate mouthwash was prescribed to the zinc acetate and CHX diacetate (ZnA) group, and the thyme (T) group was instructed to use thyme mouthwash. GI, PI and volatile sulfur compound (VSC) values were recorded at baseline and at the first week of treatment. RESULTS: The initial values of the recorded parameters did not differ significantly between the groups. In all groups, VSCs, GI and PI decreased after treatment (p = 0.001). There was no significant difference between the PI values of the groups after treatment (p = 0.188). On the contrary, the GI and VSC values after treatment were significantly different between the groups (p = 0.001). GI values were highest in the control group and lowest in the CHX group. In terms of VSCs, a significant difference was found between groups T and C, and between groups T and ZnA (p = 0.001). CONCLUSION: This study showed that the use of thyme mouthwash after periodontal treatment was effective in improving bad breath and gingivitis in gingivitis patients.

Variation of Mandibular Canal Branching Related to Anatomical Regions in Mandible: A Radiographic Study Without Contrast.

PURPOSE: Screening mandibular canal branches and awareness of these possible canal branches is vital for patient safety and surgical success. The aim of this study was to evaluate the prevalence and localization of mandibular canal branching (MCB). METHODS: This is an institutional and retrospective cohort study of patients who presented for evaluation of cone beam computed tomography (CBCT) between 2019 and 2020. The prevalence of MCB and the related foramina was estimated according to anatomical regions. Predictor variables were gender, age, anatomical region, and side of branches. Outcome variable of the study was MCB. Thus, multiple correspondence analysis was performed to determine the relationships between the categories of the variables, as well as between variables. RESULTS: CBCT images were obtained from 180 patients (n = 360 hemimandible; 90 males, 90 females). MCB was observed in 130 (72.2%) of 180 patients (mean age = 38.2 ± 11.8 years). MCB was observed in 63 (48.5%) males and 67 (51.5%) females, and the prevalence of MCB did not differ significantly according to gender (P = .618). MCB was mostly observed in the molar region (69 branches, 34.3%). Foramina were detected in 60 of 248 branches (24.19%) and were mostly observed in the retromolar region (28 foramina, 46.7%). "Quadrafid" branching was detected in 2 females (1.11%). Female patients aged 19-38 years were more prone to have MCB in molar and retromolar regions. MCB was more likely to occur bilaterally. There was also a high positive correlation among the MCB, side, and anatomical regions. CONCLUSIONS: MCB is not a rare anatomical variation, and even quadrafid branching can be observed in the hemimandible. CBCT images should be examined carefully for possible MCB to minimize postoperative complications during dental surgery.

Accuracy of the London atlas, Willems, and Nolla methods for dental age estimation: a cross-sectional study on Eastern Turkish children.

OBJECTIVES: This study aimed to estimate the dental age (DA) using the London Atlas, Willems, and Nolla methods and to compare their accuracies. METHODS: The DA was estimated using the aforementioned methods on panoramic radiograms of a total of 919 Eastern Turkish patients aged 6-14 years, of whom 459 were female and 460 were male. The overestimation and underestimation values were determined in relation to the chronological age (CA) values. The paired t test was used to compare the mean DA and CA values. Multiple regression analysis was used to derive gender-specific formulations for the three methods. RESULTS: The most accurate method for estimating the DA was the Willems method (mean prediction error 0.80), followed by the London Atlas (mean prediction error 0.83) and Nolla (mean prediction error 0.89) methods. Statistically significant differences were found only between the Willems and Nolla methods. CONCLUSION: All three methods can be used for DA estimations of Eastern Turkish children. CLINICAL RELEVANCE: Willems was the most suitable method for this patient sample. However, the London Atlas method may be preferred due to its practicability and comparable accuracy.
