0% compared to the unaffected left mandibular ramus. At the age of 12 years and 8 months, multibracket treatment was initiated. After 32 months of active treatment, proper occlusion with functional Class I canine and molar relationships was obtained, although facial asymmetry associated with the difference of ramus heights still existed. Calciumfolinate The resulting occlusion was stable during 1.5-year retention period.
Our results indicated the importance of orthopedic treatment during growth period in the patient with hemifacial microsomia involving the FSBAS.
This report proposes an efficacy of conventional orthodontic treatment for growing patients with hemifacial microsomia involved in the FSBAS.

The study aimed to compare the prospective changes in mandibular third molar angulation in high anchorage cases treated with first premolar extractions vs non-extraction orthodontic treatment.
The sample consisted of 56 nongrowing patients Group I had 26 patients with a high anchorage requirement who underwent first premolar extractions and group II had 30 patients who underwent non-extraction treatment. Pretreatment, mid-treatment, and posttreatment panoramic radiographs were obtained for group I and pretreatment and posttreatment for group II. Angle between M2 (second molar)-horizontal reference plane (HRP), M3 (third molar)-HRP, and M2-M3 were measured bilaterally. Data were analyzed using Student
test and ANOVA test (
value < 0.05).
Statistically significant increase was found between the pretreatment, mid-treatment, and posttreatment values of M2-M3 in group I (
value = 0.02 R and
value = 0.049 L) and between pretreatment to posttreatment values of M2-HRP in group II bilaterally (

The extraction of first premolars in high anchorage cases does not lead to an improvement in the angulation of mandibular third molars; moreover, the angulation worsened with extraction therapy. Prospective orthodontic patients need to be cautioned against any improvement in mesioangular impaction of mandibular third molars in high anchorage premolar extraction cases.
To externally validate the performance of a novel periodontal prediction model (PPM) for identification of diabetes among Saudi adults.
The study was carried out among 150 adults attending primary care clinics in Riyadh (Saudi Arabia). The study adopted a temporal external validation approach, where the performance of the PPM was evaluated in the same location as the development study, but at a later time to allow for some variation between samples. A case-control approach was adopted, where diabetes status was first ascertained, followed by the completion of the Finnish Diabetes Risk Score (FINDRISC), Canadian Diabetes Risk (CANRISK) tools, and periodontal examinations.
The area under the curve (AUC) of the PPM (based on the number of missing teeth, the proportion of sites with pocket probing depth
6 mm, and mean pocket probing depth) was 0.514 (95% CI 0.385, 0.642). The FINDRISC and CANRISK tools had AUC values of 0.871 (95% CI 0.811-0.931) and 0.927 (95% CI 0.884-0.971), respectively. The addition of the PPM did not improve the AUC of FINDRISC (
= 0.479) or CANRISK (
= 0.920). The decision curve analysis showed that there was no clinical benefit in adding the PPM to either tool. The PPM was updated with an overall adjustment factor for all existing predictors and three more periodontal measures.
In an external sample, the PPM had poor performance for identification of diabetes and no added value when combined with FINDRISC and CANRISK. The performance of the PPM improved after recalibration and extension.
The results underscore the value of externally validating prediction models before applying them in clinical dental practice.

The aim of this study was to evaluate the efficacy of novel antioxidant oregano against conventional antioxidants sodium ascorbate and green tea through comparison of the baseline weight percentage (wt%) of minerals prior to bleaching with values after bleaching protocols and antioxidant application by employing energy-dispersive X-ray spectroscopy analysis (EDAX).
Thirty noncarious, freshly extracted human permanent maxillary incisors without any visible defects were selected as samples. They were divided into three groups (
= 10) based on the antioxidant treatment received as follows group I-10% sodium ascorbate solution, group II-10% green tea solution, and group III-5% oregano solution. 35% hydrogen peroxide was employed for bleaching. The wt% of teeth was calculated at three time intervals. The initial wt% was calculated prior to the bleaching procedure. The second one was calculated after subjecting to bleaching protocols, and final one was calculated after antioxidant treatment using EDAX.
There was a statistically significant decrease in the calcium/phosphorus ratio for the bleached samples in comparison with the sound enamel. There was a comparable and significant increase in the calcium/phosphorus ratio values after application of the antioxidant with insignificant difference among the antioxidants evaluated in the study.
Treatment with antioxidants helped in the reversal of mineral loss, which occurred due to the bleaching procedure while the efficacy of 10% oregano on reversal of the calcium and phosphorus ratio was found to comparable to that of 10% sodium ascorbate and green tea.
Application of antioxidants after bleaching reduced the time delay in performing the adhesive procedures without compromising their clinical efficacy.

Dental professionals are more prone to get exposed to various occupational health problems. The aim is to assess various dental occupational hazards and safety measures among dentists of Odisha, India.
The present study was conducted among 572 dental professionals of both genders. A self-administered questionnaire which comprises name, age, gender, number of years of experience, type of occupational hazard, awareness of occupational hazards, safety measures practiced, and working hours per week was given to dental professionals and the responses were recorded.
545 (95.2%) dentists were responded out of 572 participants. Age group 20-40 years had 55 males and 24 females, 40-60 years had 154 males and 84 females, and >60 years had 116 males and 60 females. 220 dentists had 10-15 years of experience, 190 had 5-10 years, 60 had <5 years, 40 had 15-20 years, and 35 had >20 years. The difference was significant (
< 0.05). The most common occupational hazard was musculoskeletal disorders seen in 480 (88%), stress in 273 (50%); maximum occupational hazard (52%) was noticed in dentists with <5 years of working experience; proper safety protocols adopted by dentists were the use of sterilized instruments 99%, gloves 98%, face mask 82%, vaccination against hepatitis 54%, head cap 51%, eyewear 12.
