Effect of a varnish containing chlorhexidine and thymol (Cervitec) on approximal caries in 13- to 16-year-old schoolchildren in a low caries area.

BACKGROUND: Previous studies on the effect of the chlorhexidine and thymol-containing varnish (Cervitec((R))) have consistently shown a reduction in STREPTOCOCCUS MUTANS, while the data on the caries-inhibiting effect are conflicting. AIM: To measure the effect of a chlorhexidine- and thymol-containing varnish (Cervitec) on approximal caries in a low caries population. MATERIAL: Eighty-five schoolchildren, 13 years of age, entered the study after being selected on the basis of bitewing radiographs. Children with at least one approximal lesion were included after informed consent. METHODS: The study was carried out as a double-blind, randomized controlled trial according to a split-mouth design using Cervitec on one side and a placebo varnish on the other side. All approximal surfaces between molars and premolars were treated every 3rd month. After 2 years new bitewing radiographs were taken. A total of 73 children completed the 2-year study. RESULTS: Neither the difference in number of new lesions between the Cervitec-treated and the placebo-treated side (d: -0.21; 95% CI: -0.57; 0.16) nor the mean difference in number of already existing lesions that progressed (d: -0.01; 95% CI: -0.33; 0.30) were statistically significant (paired t test; p > 0.05). CONCLUSION: The results of our study do not indicate an effect of Cervitec on initiation or progression of approximal caries in a population with a low DMFS.

The wand versus traditional injection for mandibular nerve block in children and adolescents: perceived pain and time of onset.

PURPOSE: The purpose of this study was to compare the perception of pain and time of onset in relation to mandibular alveolar nerve block administered by a computerized anesthesia delivery system (ie, The Wand) and a traditional anesthesia system (ie, the syringe). METHODS: This study was conducted according to a split-mouth design, with both types of injections being given to all patients. Subjects consisted of 33 patients between 7 and 18 years of age requiring local anesthesia for dental restorations in both sides of the mandible. All patients were blindfolded, and the sound from the Wand machine was activated during both types of administration. Topical analgesic was placed in the area of the injection site in all cases. Pain ratings were obtained using a 10-point visual analog scale (VAS). Time of onset was measured, from withdrawal of the needle to numbness of the lower lip was reported. RESULTS: The computerized anesthesia delivery system resulted in significantly lower pain ratings than the traditional syringe. No difference could be found in time of onset between the 2 methods. CONCLUSIONS: Mandibular alveolar block analgesia seems to be less painful when using The Wand than when using a traditional syringe.
