RESUMEN

BACKGROUND/AIM: The majority of traumatic dental injuries (TDI) in childhood and adolescence occur in schools. Since school teachers are often the first responders, their knowledge about the emergency management of TDI needs to be adequate. The aim of this systematic review was to assess and analyse the global status of this knowledge as reported in previous studies and to provide recommendations for future research. METHODS: The protocol was designed as per PRISMA guidelines and registered in PROSPERO. A broad-based search using text-words and MeSH terms was performed in established databases as per a predefined strategy. Cohort-studies, cross-sectional, case-control studies and randomized/non-randomized trials without any distinction of language and year of publication were included while those without details of sampling strategy, validity and reliability were excluded. Data extraction was performed, risk of bias assessment was done by the Joanna-Briggs-Institute's critical appraisal checklist and meta-analysis was performed for four question stems using a random effects model. RESULTS: Twenty-three studies were included for qualitative analysis. Most of the studies had been conducted in Asia from 2009 to 2019. Ten studies used case-based questionnaires, mostly adapted from previous studies. Moderate to high risk of bias was observed in 14 studies. Less than 50% of teachers had witnessed a TDI in 8 studies and >75% desired to know more about TDI management in most studies. Less than 50% of teachers in 5 out of 6 studies knew about immediate replantation of avulsed permanent teeth, <25% knew about storage of an avulsed tooth in 16 studies and <50% knew about cleaning of a dirty avulsed tooth in 8 studies. Meta-analysis revealed I2 values of >95% with 17% of teachers having previous dental-trauma first-aid training and 38% knowing about replantation within 30 minutes. CONCLUSION: The awareness level in several areas of the world is unknown. Studies lacked well-designed questionnaires and teachers exhibited low self-belief and knowledge level in the majority of studies.

RESUMEN

AIM: The aim of this study was to assess the success rate of bicanalicular intubation of lacrimal drainage apparatus in chronic dacryocystitis patients who were at high risk of failure of surgery of dacryocystorhinostomy. MATERIAL AND METHODS: A total of 24 patients with chronic dacryocystitis (25 eyes) including 11 males and 13 females (age range 3-80 years) having high risk factors of failure of dacryocystorhinostomy were enrolled. Factors such as previous attacks of acute dacryocystitis, trauma in lacrimal sac region, previously failed dacryocystorhinostomies, formation of false passages in the lacrimal drainage apparatus were considered. Conventional dacryocystorhinostomy followed by bicanalicular intubation of the lacrimal drainage apparatus with Jain metal silicone the lacrimal intubation tube (20-23 gauge) was performed in all these patients. The patients were followed up at weekly intervals for two months, at 6 months and at 1 year post surgery. RESULTS: A total of 25 eyes in 24 patients (including 11 males and 3 females) were operated upon using the technique of bicanalicular intubation of lacrimal drainage apparatus with conventional external dacryocystorhinostomy. The procedure was successfully performed in 22 out of the 25 eyes. Perioperative complications included punctual damage due to recurrent attempts at passing these probes in 2 patients and mild damage to nasal mucosa in 5 patients. The majority of patients did not experience any untoward symptoms from these silicone tubes. However, in three eyes there was felt a mild foreign body sensation and two patients had chronic conjunctival erythema. The tubes could not be retained in two of these three eyes. Additionally, in one eye there was spontaneous extrusion of tubes whilst sneezing 3 months after surgery. All these three eyes had a recurrence of symptoms due to non-retention of the tubes and needed re-operation. On average the tubes were retained for a period of six months before they were spontaneously extruded or removed. Fifteen patients retained the silicone tubes for more than 1 year. The procedure gave a success rate of 76% (19/25 eyes) and these were the eyes in which the tubes had been retained for more than 6 months. The success was not influenced by the age or sex of patient, laterality of eye, aetiology of chronic dacryocystitis, or evidence of bony deformity or abnormality of the sac. CONCLUSIONS: Bicanalicular intubation for lacrimal drainage system is a simple, inexpensive and straight forward adjunct to conventional external dacryocystorhinostomy. The procedure is strongly indicated for patients with chronic dacryocystitis who are at high risk of surgical failure. Carefully performed, it gives a 76% success rate and is not influenced by the different variables examined.
