Knowledge and awareness of dental students on attention deficit hyperactivity disorder

Attention deficit hyperactivity disorder (ADHD) is a prevalent psychiatric illness marked by a short span of attention, impulsive decisions, and behavioral issues. They are vulnerable to trauma and dental problems. The dental health team faces a challenge due to behavioral disorders, cognitive deficiencies, and short attention spans. At all stages of prevention and treatment, the management of these children necessitates various changes in approach. To collect data and analyze the awareness level of dental students toward ADHD. An online portal was used for the survey and distributed to 106 dentistry students with self-structured 10 questions. The findings were gathered through the survey portal, and graphs were drawn to compare the results. The SPSS software version 20.0 was used for statistical analysis. The Chi-square test was used to determine the correlation between the variables. Forty percent of those polled are aware of ADHD, which is a mental health condition characterized by excessively active and impulsive behavior. The symptoms of a child with ADHD are aware to 31.43% of voters. About 30.48% of the respondents know the symptoms of an adult with ADHD. About 29.52% of the respondents were aware of the causes of ADHD. To conclude that most dental undergraduates are not aware of the basic characteristics of ADHD. This means that there should be a spreading of knowledge on the subject. A dental student or dentist must know how to manage a patient diagnosed with ADHD. Careful management and treatment will lead to a satisfied and happy patient. Mismanagement may cause problems in the future for both the dentist and the patient.

How Does Orthodontic Mini-Implant Thread Minidesign Influence the Stability?-Systematic Review with Meta-Analysis

BACKGROUND

Clinical guidelines are lacking for the use of orthodontic mini-implants (OMIs) in terms of scientific evidence referring to the choice of proper mini-design. Thus, the present study aimed to investigate to what extent orthodontic mini-implant thread design influences its stability.

METHODS

Search was conducted in five search engines on 10 May. Quality assessment was performed using study type specific scales. Whenever possible, meta-analysis was performed.

RESULTS

The search strategy identified 118 potential articles. Twenty papers were subjected to qualitative analysis and data from 8 papers-to meta-analysis. Studies included were characterized by high or medium quality. Four studies were considered as low quality. No clinical studies considering the number of threads, threads depth, or TSF have been found in the literature.

CONCLUSIONS

Minidesign of OMIs seems to influence their stability in the bone. Thread pitch seems to be of special importance for OMIs retention-the more dense thread-the better stability. Thread depth seems to be of low importance for OMIs stability. There is no clear scientific evidence for optimal thread shape factor. Studies present in the literature vary greatly in study design and results reporting. Research received no external funding. Study protocol number in PROSPERO database: CRD42022340970.

Palatal plane inclination on vertical growth pattern among Indians

The skeletal discrepancies in the vertical dimensions can either lead to a long face or a short face. The palatal plane inclination is one such contributing factor. The study sample comprised of 15 lateral cephalograms collected between the time period of June 2019 - March 2020 with 5 cephalograms belonging to skeletal Class I, II and III respectively. The inclination angle and mandibular plane angle were measured using the FACAD software. The obtained results were tabulated and statistically analysed using Pearson's correlation test to determine the correlation between the two variables. There was a statistically significant negative correlation between the skeletal malocclusions with a p value of 0.011. Thus, palatal plane inclination is not a major contributing factor for vertical growth pattern and it is suggestive of a multifactorial influence.
