Intervention/exposure
Study type
Interventional
Description of intervention(s) / exposure
Calcium Hydroxide was used for the treatment of Oral cutaneous sinus tract and external root resorption, ,as an intra canal dressing because of strong alkaline nature which raises the pH of root canal and kills the intra canal microbes. 1ml of paste was formed by mixing 10mg of calcium hydroxide with sterile water to form a 1% calcium hydroxide paste. The paste was packed in the root canal immediately after root canal preparation with Gutta percha point by single qualified dentist at Operative department, Rawal hospital, Islamabad. The 1st treatment session was about 60 minutes which included root canal preparation and disinfection with Sodium hypochlorite. Later the canal was packed with calcium hydroxide paste for 3 weeks. The frequency of administration of calcium hydroxide packing was once in 3 weeks. When sinus tract healed, the disinfectant was washed with Sodium hypochlorite irrigation manually and the canal was obturated with Gutta percha. The removal of Calcium hydroxide and obturation took 30 minutes to complete. All the procedure and assessment were done by the same single dentist.

Comparator / control treatment
Triple antibiotic paste has a broad spectrum antibacterial effect. It was dressed in second group of patients having Oral cutaneous sinus tract. Triple antibiotic paste (TAP) was formed by combining metronidazole, ciprofloxacin, and minocycline in the 1:1:1 concentration. Then 100 mg of each powder was combined in a container to obtain 300 mg of antibiotic powder. This powder was then dissolved in 300 ml of normal saline to yield 1 mg/ml of TAP (with a watery consistency).The paste was packed in the root canal with Gutta percha point by single qualified dentist at Operative department, Rawal hospital, Islamabad. The 1st treatment session was about 60 minutes which included root canal preparation and disinfection with Sodium hypochlorite. Later, the canal was packed with Triple-antibiotic paste for 3 weeks. The frequency was once in 3 weeks. When sinus tract healed, The disinfectant was washed with Sodium hypochlorite irrigation manually. The canal was obturated with Gutta-percha. The removal of disinfectant and obturation took 30 minutes. All the procedure and assessment were done by the same single dentist
Any patients with continued external root resorption after 3 weeks were considered for redressing with calcium hydroxide for a further 3 weeks followed by obturation after healing, at the discretion of the treating dentist.
Control group
Active

Outcomes
Primary outcome [1] 332410 0
The closure of sinus tract was assessed by passing Gutta-percha through wound. Cure of Oral cutaneous sinus tract was assessed by healed wound from physical examination by the same operating dentist.
Timepoint [1] 332410 0
6 weeks from the start of treatment or until cured;
Secondary outcome [1] 413398 0
Cure of external root resorption was assessed by radiographs i.e resorption of root stopped and there was no further decrease in the length of the root or there was continued root formation
Timepoint [1] 413398 0
18 weeks from the start of treatment or until cured;

Study design
Purpose of the study
Treatment
Allocation to intervention
Randomised controlled trial
Procedure for enrolling a subject and allocating the treatment (allocation concealment procedures)
allocation concealment was carried out. The operating dentist did not know until the patient themselves picked up the folded paper randomly, on which the disinfectant name was written, to determine to which group they are allocated and which intracanal disinfectant be used to treat them
Methods used to generate the sequence in which subjects will be randomised (sequence generation)
The 2 groups were allocated randomly by lottery method. 5 folded paper had the name of Calcium hydroxide and other 5 folded papers had the name of Triple antibiotic paste. Patients were asked to pick one folded paper. The disinfectant written on that paper was then used for the treatment of that particular patient

Summary
Brief summary
E- faecalis is found more prevalent in old untreated pulp necrosis. Calcium hydroxide is not effective against E-faecalis. However, triple antibiotic paste is broad spectrum antibiotic effective against majority of bacteria including E-faecalis. The hypothesis of the study was that may be Triple antibiotic paste was more efficient as compared to Calcium hydroxide in treating Oral cutaneous sinus tract and external root resorption. The approval was taken from the ethical committee of Rawal Institute of health sciences. The patients were first presented to Out patient department (OPD) of Rawal Institute of health sciences. Doctors from OPD were well informed of the study. So, they referred those patients immediately to the members of the study group where they had a detailed history and extra and intra oral examination.
Studies have suggested that Calcium hydroxide (CaOH) is not effective against Enterococcus faecalis and Candida albicans. Alternative, Triple antibiotic paste(TAP) consists of a mixture of minocycline, metronidazole and ciprofloxacin which is considered to have an exceptional antimicrobial activity even with E. faecalis and C. albicans.
Extensive literature search showed that no study has been done on oral cutaneous sinus tract(OCST) and external root resorption(ERR), together. Authors of majority of case reports/ case series have used CaOH as a disinfectant for treating OCST. However, no study has been done till now, to identify the best disinfectant for treating OCST and ERR, both.
The objective of the current study was to compare the efficacy of CaOH and TAP for the treatment of OCST and ERR. This helps in identifying the best disinfectant for the management of OCST and ERR.
