Oral Midazolam Vs Promethazine as Pre Sedation Medication in Pediatric Dentistry

Objectives Pre- and post-sedation effect of oral Midazolam to promethazine in2-6 yrs old fearful children for dental treatmentMethods This randomized clinical trial was carried out on a group of 26 children aged 2-6 years referred to the dental school due to their fear and multiple dental needs. Patients were selected from ASA I or II classification and scored 1 in Frankl Behavior scale. Each patient was scheduled for two subsequent visits to receive one of the two pre medications before IV sedation. Each patient served as self-control and randomly assigned to either group A: receiving Midazolam oral as premed in 1st visit or group B: receiving Promethazine oral as the premed in 1st visit. Six hour NPO was instructed prior to sedation visit. Monitoring vital signs were conducted at every 15 minutes starting with base line before any drug administration. Sedation score was recorded using Houpt Sedation scale. Post sedation problems were recorded by operator. Data were analyzed using Student t test and Kruskal Wallis.Results No significant difference was noted between the patient perceptions at the two different visits. Children did not show a significant difference on symptoms such as Crying, Movement, Sleep and overall behavior in two visits at the first 15 minutes of sedative injection. Post-operative complications were having no significant difference. Lower sickness and vomiting were reported following promethazine intake.Conclusion Promethazine seems to be as effective and as acceptable premedication as Midazolam in pediatric dentistry

Dentin dysplasia type I: a case report and review of the literature

<p>Abstract</p> <p>Introduction</p> <p>Dentin dysplasia is a rare hereditary disturbance of dentin formation characterized by defective dentin development with clinically normal appearing crowns, severe hypermobility of teeth and spontaneous dental abscesses or cysts. Radiographic analysis shows obliteration of all pulp chambers, short, blunted and malformed or absent roots and peri-apical radiolucencies of non carious teeth.</p> <p>Case presentation</p> <p>We present a case of dentin dysplasia type I in a 12-year-old Iranian boy, and the clinical, radiographic and histopathologic findings of this condition and treatment are described.</p> <p>Conclusions</p> <p>There are still many inconclusive issues in the diagnosis and management of patients with dentin dysplasia. The diagnostic features of this rare disturbance will remain incompletely defined until additional cases have been described. Early diagnosis of the condition and initiation of effective regular dental treatments may help these patients to prevent or delay loss of dentition.</p

Contamination of Dental Unit Water and Air Outlets Following Use of Clean Head System and Conventional Handpieces

&lt;p&gt;&lt;strong&gt;Background and aims.&lt;/strong&gt; Dental handpiece is a source of contamination because it is in constant touch with the oral cavity. Sterilization does not seem to be sufficient to prevent penetration of microorganisms into air and water lines of the unit, because negative pressure developed by valves (which are placed in water outlets) and post shut-off inertial rotation of handpiece result in water and debris being sucked into air and water outlets of dental unit. The aim of this study was to compare dental unit contamination following use of clean head system handpieces and conventional handpieces. &lt;/p&gt;&lt;p&gt;&lt;strong&gt;Materials and methods.&lt;/strong&gt; Twenty-two dental units in the Department of Pediatric Dentistry in Shahid Beheshti Faculty of Dentistry were used for the purpose of this study. A 1.5×108 cfu/mm3 concentration of Staphylococcus epidermis (SE) was used to contaminate the air and water outlets of dental units. Ten clean head system handpieces and 10 conventional handpieces were used for 30 seconds in the above-mentioned suspension. Microbial samples were collected from the air and water lines. Culturing and colony counting procedures were carried out. Data was analyzed by t-test; a value of p&lt; 0.01 was considered significant. &lt;/p&gt;&lt;p&gt;&lt;strong&gt;Results.&lt;/strong&gt; Results demonstrated a significantly lower SE contamination in water outlets following the use of clean head system (p&lt; 0.01). &lt;/p&gt;&lt;p&gt;&lt;strong&gt;Conclusion.&lt;/strong&gt; A lower tendency of clean head system handpieces to transmit SE compared to conventional system makes them a better choice for infection control.&lt;/p&gt
